How to Know If You Need a FIT Test for Work
A respirator can only protect you when it seals correctly against your face. That is why many employees must complete a respirator FIT test before working around dust, fumes, chemicals, infectious particles, or other airborne hazards. The test confirms that a specific make, model, style, and size of tight-fitting respirator fits the person who will wear it.
If your employer has mentioned respiratory protection, you are starting a new position, or your job duties have changed, it is worth finding out whether FIT testing is part of your workplace requirements.
What Does a Respirator FIT Test Check?
A FIT test evaluates the seal between a tight-fitting respirator and your face. It is different from simply trying on a mask or performing a quick user seal check before a shift.
Testing may be qualitative or quantitative. A qualitative test produces a pass-or-fail result based on whether you can detect a test substance while wearing the respirator. A quantitative test uses specialized equipment to measure leakage and generate a numerical result. The appropriate method depends on the respirator and the level of protection required. OSHA recognizes both testing methods.
Which Jobs Commonly Require FIT Testing?
FIT testing is generally based on workplace exposure rather than job title. It may be required for:
- Healthcare workers exposed to airborne illnesses
- Construction workers handling silica or asbestos
- Painters working around chemical vapors
- Welders exposed to hazardous fumes
- Industrial and manufacturing employees
- Emergency responders
- Laboratory personnel
- Oil and gas workers
Requirements can vary even within the same industry. If your job requires a tight-fitting disposable mask, half-mask respirator, or full-face respirator, you will likely need a FIT test. Under OSHA guidelines, employees must also receive a medical evaluation before testing or using the required respirator.
When Do You Need Another FIT Test?
Passing once does not provide permanent clearance. OSHA requires FIT testing at least annually for employees who must wear tight-fitting respirators. You also need to be tested again before using a different respirator facepiece, including a change in its make, model, style, or size.
Additional testing may be necessary when a physical change could affect the seal. Examples include a significant change in weight, major dental work, facial surgery, or scarring near the sealing surface. You should also speak up if the respirator suddenly feels uncomfortable or no longer seems to fit as it did during your test.
How Should You Prepare for Your Appointment?
Bring the respirator information supplied by your employer, along with any paperwork or authorization you were given. Because facial hair that crosses the sealing area can prevent a tight fit, you may need to be clean-shaven where the respirator contacts your face. Ask your employer or testing provider for specific preparation instructions before arriving.
During the appointment, you may be asked to perform several simple movements while wearing the respirator. These can include turning your head, speaking, and breathing normally. The goal is to make sure the seal remains effective during motions similar to those you may make at work.
