SECTION 1 - Bloodborne pathogens

Learning objectives: The learner will be able to

The Occupational Safety and Health Administration (OSHA)1 requires that anyone who can potentially be exposed to bloodborne pathogens in a workplace must receive training to stay protected. In addition, each employer must have a site-specific exposure control plan (see template) that deals with bloodborne pathogens in the workplace. This course meets the OSHA requirements for education in the workplace when used in conjunction with an orientation on your site-specific exposure control plan.

Bloodborne pathogens

What are bloodborne pathogens? They are disease-causing microorganisms that are carried through infected blood. There are many known examples, but the most notorious are the hepatitis B virus (HBV), the hepatitis C virus (HCV), and the human immunodeficiency virus (HIV).3 Moreover, there is always the possibility of discovering a new bloodborne pathogen that causes a disease with which we are not yet familiar.3

Both hepatitis B and hepatitis C affect the liver. For this reason, it is important to understand what this organ does for the body. Why is your liver so important? Your liver is located in the right upper quadrant of your abdomen below the diaphragm and is essential for many bodily functions. It is so important that you cannot live without it. Let’s take a look at some of the chief roles of the liver.

First and foremost, it acts as a filter. Deoxygenated blood carrying nutrients, toxic substances, and medications are delivered to the liver via the hepatic portal vein. This blood then flows through the liver tissue to specialized capillaries known as sinusoids. Within the sinusoids, blood is filtered through the hepatic cells (hepatocytes) to process or store nutrients and to remove waste materials and by-products from the bloodstream before they affect the rest of the body. The liver also assists with the removal or release of sugar within the blood depending upon its level. Using chemical enzymes that are stored there, it converts sugar into glycogen which is utilized by the body to create energy. When the body’s blood glucose level is too low, the liver breaks down glycogen and releases sugar into the bloodstream for use by the body.

The liver also stores minerals, proteins, and vitamins until they are needed by the body at which time they are released back into the bloodstream. These include vitamins A, D, and B-complex. One of the most important vitamins stored in the liver is B12 which is used to make red blood cells. Hemoglobin—the complex protein that carries oxygen and causes blood to be red—is also stored in the liver.

Last, but not least, the liver can manufacture blood proteins such as fibrinogen. Fibrinogen is necessary for the body to form blood clots. Without fibrinogen, a person could bleed to death from a minute injury. The liver also manufactures albumin. Albumin is a protein that contributes to the body’s ability to maintain fluid balance. A small amount of disease-resisting globulin is also manufactured here.

Hepatitis and other diseases that attack the liver can prevent the liver from performing any or all of the above functions. The seriousness of the disease process depends on the amount of damage done and how much of the liver’s function is prevented or decreased.

Bodily fluids

Many bodily fluids present a risk for the transmission of infectious diseases, but blood is the most common. Blood is responsible for most transmissions of disease within the healthcare setting.

Other potentially infectious materials (OPIM) include the following body fluids: semen, vaginal secretions, cerebrospinal fluid, synovial fluid, pleural fluid, pericardial fluid, peritoneal fluid, amniotic fluid, saliva in dental procedures, any body fluid that is visibly contaminated with blood, and all body fluids in situations where it is difficult or impossible to differentiate between body fluids. Note that urine is not explicitly included in this list — this is because urine does not present a risk for the transmission of bloodborne pathogens unless it contains blood.5

Universal precautions were developed by the Center for Disease Control (CDC) in the late 1980s in response to the HIV outbreak. The effective guideline defines that all bodily fluid is treated as if they were known to be infectious. Even though every patient is treated as if they carry an infectious disease, communication of an infectious disease remains imperative amongst healthcare providers.

Universal precautions protect against the pathogens that we don’t know about. For example, if we had practiced universal precautions before the HIV or hepatitis outbreaks, the impact of outbreaks would have been much smaller. The Healthcare Infection Control Practices Advisory Committee (HICPAC) updated universal precautions to standard precautions and defined in greater detail the guidelines. The entire position paper is available here: https://www.cdc.gov/infectioncontrol/guidelines/isolation/index.html

Standard Precaution recommendations from the CDC contain the following ten subdivisions of recommendations:

  1. Hand hygiene
  2. Personal protective equipment (PPE)
  3. Respiratory hygiene/cough etiquette
  4. Patient placement
  5. Patient care equipment and instruments/devices
  6. Care of the environment
  7. Textiles and laundry
  8. Safe injection practices
  9. Infection control practices for special lumbar puncture procedures
  10. Worker safety

All recommendations are based on the premise that each patient or piece of equipment is considered contaminated and treated as such.

Hepatitis B

The virus that causes hepatitis B is HBV (hepatitis B virus). It is most commonly transmitted through blood, semen, or OPIM. Anyone who is at risk of exposure should be vaccinated against hepatitis B. The vaccination is available through your primary care physician and most local health department offices. It is a three-shot series—the second injection is received about a month after the initial dose is given, and the third injection is received six months after the initial dose. Once the vaccination series is completed, it is effective in preventing hepatitis B in 95% of exposures.

In the United States, there are approximately 2 million people who have chronic hepatitis B. The majority of them are unaware of their infection. However, they remain infectious to others, making this a dangerous situation.

There are 257 million who are infected worldwide. Appropriate screening and education regarding hepatitis B are imperative to stopping the spread of this virus. The US Preventive Services Task Force (USPSTF) and CDC recommend that all patients be screened for hepatitis B using a surface antigen blood test.

When someone is first diagnosed with hepatitis it is considered an acute infection. After the patient has it for 6 months or longer it is deemed to be chronic. Even though most patients are unaware of their infection they continue to infect others and may already have severe liver damage before they are aware of their symptoms. It can cause inflammation of the liver, fibrosis (scarring), cirrhosis (severe scarring that decreases function), and can cause liver cancer.

The only way to contract the virus is through contact with infected blood or bodily fluid. It is not transmissible by touching, kissing, or casual contact. The most common infection occurs when it is transmitted from an infected mother to the child during birth. Infected blood after an injury or scratch or exchanging bodily fluid during sex can also transmit the disease. Sharing unsterile needles have become a particularly large problem given the current opioid addiction problem in the United States. Additional behaviors that place a person at high risk of hepatitis B include:

Most symptoms appear approximately three months following exposure but can appear as early as six weeks and as late as six months. The symptoms usually last for several weeks but can last for six months. Most adults fully recover. Some people remain with the HBV virus (chronic hepatitis B). Most people remain symptom-free for 20–30 years. Although symptom-free, once diagnosed, you must have your liver enzymes checked regularly to monitor for liver damage from chronic infection.

Symptoms of hepatitis B include:

Hepatitis C

Hepatitis C is caused by the hepatitis C virus (HCV). It is spread when blood from a person infected with the virus touches the blood of someone who is not infected. It does not spread by casual contact, such as drinking glasses, food, or toilet seats. There are certain groups of people that are at a higher than average risk for contracting hepatitis C. They include:

The CDC recommends that all baby boomers (born 1945–1967) be tested for hepatitis C. They were infected in the 70s and 80s when infection control standards were not as effective as today. The virus was not discovered until 1989. Donated blood was not screened until 1992. Many of these patients have had chronic hepatitis C that did not cause symptoms for decades and are only now starting to show signs of liver damage from the disease. Hepatitis is curable and new treatments are being tested every day.

Symptoms of the disease can range from acute and very bothersome to somewhat vague and hard to recognize. These include:

Hepatitis A

Hepatitis A is not a bloodborne pathogen, but nonetheless is an infectious disease that needs to be discussed in the environment of Tattoo Parlors and medical facilities as well. Hepatitis A is also a disease causing inflammation of the liver, but is transmitted via a different method than hepatitis B and C. This virus is transmitted from person to person via fecal material. This can occur with direct contact with feces, or more commonly with contact with contaminated water (sewage contaminated water) or food contaminated with fecal material. This occurs most commonly with produce that has been contaminated with the feces of animals from the farm on which it is grown. It is then consumed without proper cleansing and the virus is spread to people. This can also occur by person to person contaminated food. An individual’s hands are contaminated with fecal material from failure to wash after using a bathroom. That same individual then prepares food that is then contaminated with the virus and consumed by another individual who then becomes hepatitis A positive.

Hepatitis A, unlike B or C does not result in a chronic liver infection. It is however a serious and long-lasting disease. Symptoms can last up to two months and include

It is unusual, if not impossible to be infected with hepatitis A more than once in a lifetime because the antibodies that respond to the infection last a lifetime and prevent the patient from acquiring the disease a second time. There is a vaccination for hepatitis A but can be expensive. For this reason it is normally reserved for those at high risk, such as people working in 3rd world countries, workers exposed to high risk environments such as sewage facilities and other people who would be expected to come in contact with the virus on a regular basis.

Staph infections – methicillin resistant Staphylococcus aureus (MRSA)

Staph is a bacteria that is present on skin in many people. Healthy people carry on their skin or in their noses but are not infected by it and unless tested do not know of its existence. It is not a problem unless it enters your body, usually through an opening in your skin, such as an injury or commonly when obtaining a tattoo. Another variety of staph infection is methicillin resistant Staphylococcus aureus. This is an infection that can attack any area of your body but most commonly causes skin infections. It is difficult to treat because it is resistant to the most common antibiotics used to treat staph infections. Usually the person gets no more than a rash, irritations that look like blisters or other skin presentations. It is usually self-limiting. MRSA can be introduced into more systemic areas such as lungs, the urinary tract and other internal organs. This most commonly occurs at the site of a surgical wound. For this reason tattoo parlors are a high risk area for MRSA.

MRSA or other staph infections can also be transmitted by touching surfaces or people that have the bacteria on them. Regular handwashing and careful cleaning of surfaces in areas that may be contaminated are the best ways to prevent the transmission of all staph infections.

Staph infections, because they are bacterial, respond to antibiotic treatment. MRSA requires the use of much stronger antibiotics. As its name implies, it is resistant to the most common antibiotics used to treat staph infections.

IMPETIGO is caused by staph infections as well. It is usually an issue for small children from age 2–5 but is not unheard of in older children and adults. It presents much the same way with rash. The rash of impetigo usually shows up on the face, arms and legs. It is almost always self-limiting but in bad cases can require antibiotics. The best prevention is general cleanliness including hand washing, limiting touching of the face, eyes and mouth and keeping surfaces cleaned and disinfected.

Tuberculous (TB)

TB is a serious infection that affects the respiratory system (lungs). It was extremely rare until its resurgence in the mid to late 1980’s when the HIV virus made its debut. TB is most common in people who have depressed immune systems. TB is present in many situations but for the most part, individuals’ immune systems are able to fight it off and they do not contract the virus. However, for people who may have a depressed immune system including the elderly, the ill, people with chronic infections or those taking immunosuppressive medications such as chemotherapy, TB can be a major issue.

TB is transmitted through droplets such as those that are spewed through the air with sneezing and/or coughing. Droplets can be spread within 6 feet of those coughing or sneezing. Covering coughs or sneezes with the arm or a tissue is the best way to avoid contamination. Washing hands frequently and avoiding touching the face and eyes is helpful. Symptoms of TB infection are sometimes overlooked because they mimic the signs and symptoms of other much more common diseases. They include:

TB that goes untreated or is resistant to treatment can affect other organs in the body such as kidneys or even the brain. It is important to recognize the signs and symptoms of TB and begin treatment. Although there are some vaccines available in third world countries where TB is much more common, they are not recommended or used in the United States.

There are no specific preventions recommended in the tattoo environment because it is impossible to identify those who are TB positive. Good hygiene practices including regular washing of hands and disinfecting of surfaces within the parlor are the best preventative measures available.

Scabies

Scabies is not an infection, but rather an infestation. It is however contagious. The most common people to contract scabies are those living among large numbers of people such as prisons, institutions and even children who are in child care facilities. It is literally mites called sarcoptes scabiei that live and reproduce in the outer layers of the skin. They can be present for months before they cause symptoms. They will present with:

Although they can live anywhere dark, moist areas are best suited to them. So folds of the skin, between fingers, at the waistline or in the navel are common. Scabies are spread with skin to skin contact. Literally the mites climb from one person to another so casual contact is not enough time for this to happen. Scabies can cause other bacterial infections such as impetigo because of damage to the skin surface.

Scabies is NOT self-limiting. They must be killed with prescription creams that kill the mites. Leaving scabies to “see if they go away” will just give the infestation time to increase. Early treatment is essential in controlling scabies. In addition to the treatment of the “ground zero” patient, people in close contact such as spouses or cellmates should be treated as well to kill the mites before infestation can take hold.

Ringworm

Ringworm is not a worm. It is a fungal infection of the skin. It is most common in the scalp, feet, nails, groin. It will appear as red patchy rash. It is the cause of what is commonly known as “jock itch” and “athlete’s foot.” Depending upon the severity of the presentation, it can be treated with over the counter creams and/or prescription strength creams or in extreme cases oral prescription medications. Because it is fungal, it likes warm, wet areas. Prevention is aimed at not providing those areas. Drying completely following bathing, wearing loose clothing, washing bedding and clothing regularly during outbreaks are just a few ways of containing spread.

Molluscum contagiosum

It is a viral infection of the skin that presents with flesh colored, dome shaped lesions that almost always have a small dimple in the middle. They are caused by the poxvirus. It is spread by direct contact or sharing of objects such as towels. It can also be spread during sexual intercourse. It is considered highly contagious. Prevention is the same as most contagious diseases; frequent hand and surface washing and disinfecting.

Herpes zoster

Herpes zoster is a reactivation of the chickenpox virus that has laid dormant for a period of time. It usually begins with pain along a nerve route with the eruption of a red rash within 2–3 days. There is a vaccination available for its prevention. Older patients are at particular risk of this infection. It is treated with anti-viral prescription medications like acyclovir, famciclovir and valacyclovir.

Sometimes wet compresses can help the pain, but most often it is severe enough to require system pain control. The only time that herpes zoster is contagious is when there are active blisters on the person. In the environment of a tattoo parlor, clients with active blisters should be refused.

Herpes simplex

There are two types of herpes simplex presentations. Both are caused by viruses, (either type 1 or type 2). Type 1 causes sores around the mouth (cold sores) and type 2 causes sores and blistering around the genitals. Type one is usually spread by oral secretions such as during kissing or sharing toothbrushes. It can be spread with oral sexual contact and result in type 1 virus being present as genital sores. Type 2 is spread during sexual contact or during childbirth. Both forms of Herpes can remain dormant for long periods of time and then resurface from time to time. They are only contagious when there are active sores present. There is no cure, but treatment is aimed at reducing the amount of time of an outbreak or lengthening the time between outbreaks. Because it can be spread with contact, those with visible active sores should not receive tattoos during active periods.

General reduction of transmission

You probably noticed that the prevention of many of the above bacterial and viral diseases are similar. Good hygiene is essential, especially in an establishment such as a tattoo parlor where skin integrity is interrupted for the procedure. Handwashing is the single largest defense against the spread of any disease. In addition, cleaning and disinfection of surfaces within the environment is extremely important. Policies should be in place for the routine disinfection of all surfaces that come in contact with clients and or artists.

In addition, policies should be in place to refuse service to anyone with active sores of any kind on the skin and/or active respiratory illnesses. Common sense precautions like these go a long way in preventing the spread of infectious diseases.

The Skin

The skin is the largest organ in the human body. The skin of the average adult has an area of 20 square feet. It has several functions. It protects the underlying organs and systems from infection and injury. It houses many sensory nerves that provide communication to and from the brain. The deeper the layer of skin, the more vascular (blood vessels) it is. Dermatology is the study and treatment of the skin and the disorders that occur there. Before we can understand what can go wrong, we need to take a look at the skin and how it is supposed to work.

The skin is composed of three main layers. Picture two pieces of Saran wrap, moist laying on top of each other. The upper level is the one we see and deal with daily. It is called the EPIDERMIS. It is the outermost layer and is composed of four or five layers of epithelial cells. The epidermis provides a waterproof barrier and is responsible for our skin tone. Skin is classified as “thick” or “thin” skin. This depends upon the number of layers present. Most of the skin is classified as thin. Thick skin is found only on the palms of the hands and the soles of the feet. The epidermis does not contain blood vessels or other structures such as lymph vessels or sweat glands. The color of the skin is created by melanocytes that produce pigment. They are located in this layer as well.

The DERMIS is the main layer of skin and contains blood and lymph vessels. Also contained in the dermis are the hair follicles and sweat glands. It is made of tough connective tissue. Its job is to be a cushion against stress. It is the part of the skin that provides the sense of touch and heat by housing the nerve endings that experience those sensations. It is responsible for the elasticity of the skin.

The HYPODERMIS is the layer just beneath the dermis. It is composed of fat and connective tissue. It is a well-vascularized (many blood vessels) layer that also contains connective tissue and fat. It is the place in the skin that stores fat to work as insulation. It is the hypodermis that stores the fat that everyone tries to lose while dieting.

Disease and conditions of the skin

Most common diseases of the skin present with a rash. Although some rashes are due to disease, most are secondary to an irritation or an exposure to something that has contacted the skin. A general term for these rashes or inflamed areas is DERMATITIS. It literally means “inflammation of the skin.” Contact dermatitis occurs when the skin is exposed to something that causes an inflamed reaction. This can be from environmental sensitivities or direct contact such as a new laundry soap. It is treated with ointments, or in particularly large cases, steroids.

ECZEMA is a skin condition that is caused by an overactive immune system. The immune system works to attack the skin and causes an itchy rash. It can be limited to a small area, or in some cases can be systemic. It can be quite debilitating to patients with large outbreaks. Treatment for smaller areas involves moisturizers and lotions that can be purchased over the counter. For larger areas, there are prescription medications available for treatment.

PSORIASIS is an autoimmune skin condition that causes silver, scaly plaques on the body. Most appear on the limbs but can be on any body part. The skin thickens and can look like severe burns. Psoriasis can cover large portions of the body. This condition usually is found in infants and young children but can continue through adulthood. In adults rashes tend to be larger and are permanently itchy. As with eczema, over the counter creams and ointments are used for small cases. Larger cases require the use of prescription medication.

VITILIGO results from the loss of pigmentation in the skin. White patches appear on the skin in sharp contrast to the normal skin tone of the patient, especially in areas commonly exposed to the sun. It can spread across large body areas over a period of years. There are no known cures for this condition.

ACNE is the most common skin condition, particularly in adolescents and young adults, although it can continue throughout life. It appears with pustules that appear as red pimples that can have pus at the tips. They can also present as painful lumps that are just underneath the surface of the skin. They are treated with creams that can be purchased over the counter. Rarely do they require prescription medications for treatment, although they do exist.

CELLULITIS is inflammation of the dermis and subcutaneous tissues that is secondary to an infection. It is red, warm to the touch and quite painful. If large, it can become a systemic infection. It is treated with antibiotics.

While there are thousands of diseases that affect the skin, we have tried to touch on the most common. It is important to the tattoo artist that he/she recognizes that disorders of the skin do exist and that they can have serious consequences. Before placing a tattoo on what appears to be damaged or diseased skin, one should ensure that the client has been seen by their physician and have been cleared to have the tattoo performed.

In addition to diseases and conditions of the skin, there are complications resulting from tattoos that may occur. The tattoo must be aware of them and educate their client to be alert to watch for them. We will touch on the most common ones here.

INFECTION is by far the most common. It can also be the most dangerous because if left untreated can become systemic and cause major health issues to the client. It can occur immediately after getting a tattoo or can be delayed by days or even months. Most infections begin as a redness that becomes darker and spreads instead of the normal irritation of tattooing that diminishes and disappears. It can be itchy and painful. The client may develop a fever or chills. The client should be directed to seek attention from their physician if any of the above occurs.

RASH BECAUSE OF ALLERGY Some clients may exhibit signs of an allergic reaction to the ink used in tattooing. They can be immediate or even delayed by years. Some clients may exhibit no signs of an allergy and then following another medical procedure, like a joint replacement or the start of treatment for certain diseases, experience an allergic reaction to the ink. Normally it presents with redness and swelling around the area of the tattoo. The skin can crust and flake, or watery fluid may leak from the site. You may observe small pimply bumps on the skin around the tattoo.

Serious reactions may occur (most often immediately after or during tattooing). They include racing heart, trouble breathing, difficulty swallowing, chest tightness, dizziness, serious pain, flushing or hives. If any of these occur, this is a true medical emergency. 9-1-1 should be called immediately.

A mild reaction will present with a noticeable change within the skin that has been inked. It can be thickened or red, itchy, or painful. If this lasts more than 1–2 weeks the client should be directed to see their physician or dermatologist.

HIV and AIDS

HIV (human immunodeficiency virus) is a virus that is present within the same bodily fluids as those discussed with hepatitis. It attacks the body’s immune system, specifically white blood cells called T cells. After a while, the virus can destroy the T cells to the point that the body has a difficult time fighting off infections. These are referred to as opportunistic infections. They are the most common cause of death in patients with HIV. Certain cancers can also occur because of the impacted immune system. When an HIV patient acquires an opportunistic infection or cancer they are said to have AIDS (acquired immunodeficiency syndrome). This is the final stage of infection with HIV. Not everyone with HIV develops AIDS.4

Treatment for HIV has moved ahead leaps and bounds and is now very successful. We will discuss treatment options later in this section. Before the introduction of ART (a common treatment for HIV positive patients), that occurred in the 1990s, people who were HIV positive would rapidly progress to AIDS with an extremely high mortality rate.

HIV is only transmitted via HIV positive blood or OPIM. It is not transmitted by casual contact such as kissing, sweating, or tears. You cannot contract HIV from pets or sharing toilets or food sources. HIV is most commonly transmitted through sexual behaviors or the sharing of needles. HIV can be spread by the following:

There is no vaccine available for HIV and there is no cure. There are, however, many treatments available for HIV positive people that can substantially prolong life.

It can take weeks to months after exposure for a person to test positive for HIV. It can take even longer for symptoms to occur. Symptoms of HIV can include any or all of the following:

Title 29 of the Code of Federal Regulations: https://www.osha.gov/pls/oshaweb/owadisp.show_document?p_id=10051&p_table=STANDARDS

Bloodborne pathogens can be scary! People who do not understand the risks and how to protect themselves can be very anxious about blood and OPIM. The possibility of exposure in the work environment can be a considerable stressor.

This regulation is the standard requirement for bloodborne pathogen programs and safety in all workplaces that have employees who may be directly exposed to blood. Tattoo artists, healthcare providers, dentists, and hygienists are a small example of those at risk.

States may have standards that go beyond those set forth by the Federal Government under Title 29. The standard for each state is accessible by accessing the website for their Department of Health Regulations and then searching for “Bloodborne Pathogens Standard.”

Although unusual, some local jurisdictions have elected to enact regulations in addition to those provided at the federal and state level. The most common of these are written to regulate tattoo artists who are functioning within their jurisdiction.

https://www.osha.gov/SLTC/etools/hospital/hazards/hazards.html is a comprehensive review of the Bloodborne Pathogens Standard with potential hazards and possible solutions to each section. This is an excellent reference if you are writing your company’s bloodborne pathogen policies and procedures.

How does exposure occur?

To protect ourselves from exposure, we have to first understand how it happens. Although we are dealing with bloodborne pathogens, you need to keep in mind that other body fluids may be infectious as well. Saliva, vomit, or even droplets from sneezing may contain blood, so all of these fluids are treated as if they are contaminated.

The following is a list of bodily fluids that may carry bloodborne pathogens.

The microorganisms that cause diseases such as HBV, HCV and HIV are present in the blood of patients who are already infected. Exposure occurs when these pathogens gain entry into your bloodstream in amounts significant enough to cause disease. The amount needed to contract the disease differs depending upon the type of pathogen involved and how well your body can fight it off.6

Infected blood can enter the body in several different ways. You can be splashed with it, or you can be stuck with a needle or other sharp object that has been contaminated with blood or body fluid.7 It can also enter your body via your eyes, nose, mouth, or opening in your skin such as a cut or large scratch.

Being exposed to contaminated blood does not necessarily mean that you will become infected. Whether or not you contract the disease will depend on the concentration of germs/viruses in the contaminated blood, the amount of blood that enters your body, and how effective your body is at fighting off diseases (your immune system). Vaccinations play a significant role in preventing the development of diseases that we may be exposed to in many different environments.

The best way to deal with exposure is to prevent it in the first place!

Several factors need to be present for a successful exposure to occur.

Prevention of exposure

There are two ways to prevent exposure. First, to minimize the chances of accidental exposure in the workplace, make sure that proper practices are in place. This can be achieved by educating workers on the safe handling of blood and body fluids. The second is to protect individuals from exposure by providing them with personal protective equipment (PPE).

The guidelines that are followed to minimize exposure to bloodborne pathogens are called universal precautions.8 Universal precautions not only protect against diseases that we are aware of such as hepatitis or AIDS but even against those that may not have been discovered yet. Universal precautions assume that all blood and body fluids are contaminated. Universal precautions require that all blood and OPIM be treated as if they are infectious. This means that you should be as careful with EVERY client/patient as you would be with a client/patient whom you know carries an infectious disease.

Sanitation

The work environment must be maintained, clean, and sanitized at all times. Surfaces that do not require sterilization will be decontaminated after each use using a hospital-grade disinfectant solution. The solution can be an EPA-registered tuberculocidal disinfectant or sodium hypochlorite 0.5% concentration, by volume (household bleach is 10% concentration in water). The sodium hypochlorite solution, once correctly mixed, should be dated—do not use if it is more than 24 hours old.

All work surfaces must:

All surfaces in the work environment will be cleaned and sanitized between patients and clients and after any contamination or exposure to blood or OPIM.

Liquid waste, such as sanitizer, towels, and liquid used for cleaning will be placed in bags and containers that are

Biohazard containers and bags should be stored in a locked area that is not open to the public. The room should have a biohazard symbol prominently displayed on the door.

There must be two separate sinks—one for cleaning equipment and one for handwashing. The handwashing sink must have single-use soap and disposable towels or a hand dryer readily available. No reusable towels are permitted.

Choices of Disinfectants:

Both of the above disinfectants meet the requirements for use when disinfecting surfaces within a tattoo facility.

Disinfectants for Instruments:

Remember that Safety Data Sheets (SDS—formerly known as Material Safety Data Sheets, or MSDS) must be placed in an area that provides the employees with easy access. Each chemical that is present in the facility must have an SDS sheet available at all times.
