OSHA stands for the Occupational Safety and Health Administration, a government organization created in 1970 as part of the Occupational Safety and Health Act. Its job is to ensure safe working conditions across all types of industries, including healthcare, making it another organization, on top of CLIA and CAP that has authority over safety regulations in your laboratory. For example, OSHA has a section on formaldehyde, which provides guidelines for proper training, PPE, and disposal of formaldehyde contaminated clothing.


Several of the OSHA formaldehyde regulations specify training requirements, such as only those who are properly trained may remove contaminated material for cleaning or disposal (1910.1048(h)(2)(III) and only people who are properly trained to recognize hazards of formaldehyde may enter regulated areas 1910.1048(e)(2).

These regulated areas are those defined in the previous sections as areas “where the concentration of airborne formaldehyde exceeds either the TWA or the STEL”. These regulated areas must have signs posted at entrances notifying that there is potential danger from formaldehyde, that it may cause cancer, skin, eye and respiratory irritation, and the area is available to authorized personnel only.

To be in compliance with OSHA your lab should have a training program for anyone exposed to formaldehyde at or above 0.1 ppm. Training must be completed when they are initially assigned to the area of formaldehyde exposure, whenever there are new conditions impacting the formaldehyde exposure, and at least once annually. OSHA also specifies what must be included in the training, which includes items such as, symptoms of formaldehyde exposure, how to limit exposure through safety, proper use of PPE (personal protective equipment), emergency clean up, and how to report symptoms to your employer.

Personal Protective Equipment (PPE)

PPE refers to personal protective equipment. PPE is essential for protecting your skin, as well as your clothing from formaldehyde contamination. OSHA requirements specify that PPE that has become contaminated must be cleaned or laundered before reuse, and this contaminated equipment or clothing, should NOT be taken home once contaminated. Any clothing that is contaminated is required to be treated as, and disposed of as, hazardous waste. If proper PPE is in place you shouldn’t be getting formaldehyde on your clothing. If you are finding contamination to be a regular problem, you will want to look at your lab’s policies for safety in general, as you may be violating other OSHA requirements for hazard communication, ​chemical hygiene, etc.
