Respiratory protection quiz: OSHA respirator rules

A respirator only protects if it is the right type, fits the face and is worn correctly every time. OSHA's respiratory protection standard builds a whole program around that: medical evaluation, fit testing, seal checks, maintenance and yearly training. This quiz reviews the rules workers and supervisors get asked about most.

Respiratory protection quiz: OSHA respirator rules (14 questions)

OSHA respiratory protection (29 CFR 1910.134): the written program, medical evaluation, fit testing, facial hair and user seal checks, NIOSH respirators, IDLH atmospheres, inspection, voluntary use and annual training. Free practice quiz with instant feedback; every explanation cites the 29 CFR paragraph it is based on. Independent review material: not affiliated with or endorsed by OSHA, not an OSHA Outreach (10/30-hour) exam, and it does not replace the training and evaluation your employer must provide.

When a written program is required

Wherever respirators are necessary to protect health, or whenever the employer requires them, the employer has a written respiratory protection program with worksite-specific procedures, run by a qualified program administrator (29 CFR 1910.134(c)). It covers selection, medical evaluation, fit testing, use, maintenance, breathing air quality and training. Respirators, training and medical evaluations are provided at no cost to employees (1910.134(c)(4)).

Voluntary use is different: when an employer allows it, employees get the information in Appendix D, and those who only use filtering facepieces (dust masks) voluntarily need not be in the written program (1910.134(c)(2)). Respirators must be NIOSH-certified (1910.134(d)(1)(ii)).

Medical evaluation and fit testing

A medical evaluation comes before the fit test and before required use (1910.134(e)(1)).
Tight-fitting respirators are fit tested before first use, with any different facepiece, and at least annually, plus whenever facial scarring, dental changes, cosmetic surgery or weight change could affect fit (1910.134(f)(2)–(3)). A quantitative test is passed with a fit factor of at least 100 for half masks and 500 for full facepieces (f)(7).
Facial hair between the face and the sealing surface is not allowed with tight-fitting facepieces, and a user seal check is done every time the respirator is put on (1910.134(g)(1)).

Use, maintenance and training

Routine-use respirators are inspected before each use and during cleaning; emergency respirators at least monthly (1910.134(h)(3)). Employees leave the area to wash, when they notice breakthrough or more breathing resistance, or to change filters or cartridges (g)(2)(ii). Training comes before required use and is repeated annually; each employee must be able to show they know why the respirator is needed, its limits, how to put it on, check the seal, inspect and store it, and the medical signs that may prevent its use (1910.134(k)).

Using the quiz

Play the quiz before the annual fit test: answers come up on screen with their paragraph of 1910.134, and the seal check question is a good moment to have everyone do one. Quizhat is an independent tool, not affiliated with or endorsed by OSHA.

Frequently asked questions

How often is respirator fit testing required?

Before first use, whenever a different facepiece is used, and at least annually for tight-fitting respirators, plus after physical changes that could affect fit (29 CFR 1910.134(f)).

How often is respirator training required?

Before the employee is required to use a respirator, then annually, and sooner when changes or gaps in knowledge make it necessary (29 CFR 1910.134(k)).

Can workers with beards wear tight-fitting respirators?

Not when facial hair comes between the sealing surface and the face or interferes with valve function (29 CFR 1910.134(g)(1)(i)(A)). Loose-fitting respirators are a different case.

Do dust masks worn voluntarily need a written program?

Employees whose only use is the voluntary use of filtering facepieces (dust masks) need not be in a written program, but they must get the information in Appendix D of 1910.134.

Is this the OSHA respirator test?

No. It is an independent practice quiz written from the text of 29 CFR 1910.134; the employer provides the required training and fit testing.
