Identify the hazard
Start with what is in the air, how much is present, how long the work lasts, and whether oxygen may be limited. The hazard determines which type of protection is appropriate.

Workplace respiratory protection
Fit is part of protection
Filtration matters, but it is not the whole decision. The respirator must match the hazard, fit the individual wearer, seal correctly, and be used as part of the employer's respiratory protection program.
The complete protection decision
Four checks come before the claim.
A respirator can only help when the product, the hazard, the wearer, and the way it is used all line up. These four checks create a clear place to begin.
Select the right respirator
Match the respirator, filter, cartridge, and current approval status to the actual workplace need. A particulate filter does not protect against every gas, vapor, or unknown atmosphere.
Confirm the individual fit
When a tight fitting respirator is required, the wearer must be fit tested with the same make, model, style, and size that will be used on the job.
Check the seal every time
A user seal check is a quick check performed each time the respirator is put on. It helps the wearer confirm that the facepiece is seated correctly before entering the work area.
Two checks with different jobs
A fit test and a seal check are not the same thing.
Both matter for tight fitting workplace respirators, but they happen at different times and answer different questions.
Does this exact respirator fit this person?
A fit test evaluates the seal between the wearer and a specific make, model, style, and size. OSHA requires it before initial use, when a different facepiece is used, and at least annually for required tight fitting respirators.
Is the respirator seated correctly right now?
The wearer performs this quick check every time the respirator is put on. It can identify a seating problem, but it does not replace the formal fit test.
Where protection can break down
A filter is only one part of the system.
OSHA guidance makes the larger point clear. Selection, fit, use, training, care, and program oversight work together.
Wrong protection for the hazard
A strong filtration claim does not make one respirator appropriate for every atmosphere. Selection begins with the workplace hazard.
No confirmed fit for the wearer
Faces differ. One tight fitting model or size will not provide an acceptable fit for every person.
Something interferes with the seal
Facial hair, eyewear, hair, or other items can interfere with the sealing surface and allow contaminated air to leak around it.
The respirator is used incorrectly
Training, putting the respirator on correctly, checking the seal, maintenance, cleaning, and storage all affect protection.
