In some laboratories, the use of Personal Protective Equipment (PPE) may be confusing to staff. However, a look at OSHA’s Bloodborne Pathogens and Chemical Hygiene Standards should make clear the requirements for proper PPE selection and use.
Both standards speak clearly to the necessity of PPE when working in the laboratory. Different PPE is needed for different tasks. Lab coats are always necessary in the lab for protection against blood and body fluid splashes or chemical splashes. Plastic aprons may also be used as extra protection in areas where gross tissue work is performed. Lab coats should be buttoned, the sleeves should not be rolled up, and they should be knee-length.
Gloves are needed when handling blood, body fluids, or chemicals, but different gloves may be used for different tasks. Many labs are turning away from using latex gloves because of allergic reactions by staff. Nitrile gloves have become the norm in recent years. However, make sure you have the correct gloves for the duties being performed. Some manufacturers make nitrile gloves that act as a barrier against blood and body fluids, but they do not provide protection against chemicals. While these will be fine while running a CBC in hematology, they won’t provide enough protection when changing the stainer. Be sure to use chemical-resistant gloves for this and other tasks (gram stains, handling chemistry reagents, pouring acids, etc.). Check the package if you are not sure about the proper use of gloves.
Goggles or face protection is important PPE that is widely under-utilized. Do you carry open specimens in the lab? What about carrying a rack of specimen tubes to or from an analyzer? That is a task that creates a risk for exposure, and face protection should be used. Are you pouring a chemical? Protection is necessary. Help your staff avoid all exposures to the eyes or mucous membranes.
The OSHA standards mentioned above also require that PPE is removed before leaving the laboratory. Do not wear lab coats or gloves to another location outside the laboratory. Does a procedure need to be performed in another area that requires PPE? If so, bring fresh PPE with you for use in the treatment area and dispose of it before returning to the lab.
In a laboratory, all areas should be considered hazardous, bio-hazardous, or contaminated. Do you have a desk area in the lab where only paperwork is done? I have always said that if there is an area in the lab where there are no patient specimens or chemicals, then one could consider the area “clean.” However, that does not mean that food or drink can be consumed there or that no PPE is needed. Remember, you are still in the walls of a laboratory, and accidents may occur. It is acceptable to label the area as “clean” so that gloves are not needed for the computer or phone, but a lab coat would still be required.
Remember, if an OSHA inspector arrives, he will be looking to see that all aspects of safety regulations are being followed. Keep your employees safe and keep your facility from unnecessary fines by using PPE where and whenever needed.
