OSHA Respiratory Protection Regulations Quiz
What medical condition may prevent respirator use?
Can a worker's supervisor be present during the administration of the medical evaluation?
Yes, if provided for in published company policy
No, if worker feels uncomfortable in presence of supervisor
On a medical evaluation questionnaire can an employer include only those questions it prefers?
Yes, provided that employer has posted questions in a public area, such as a break room
No, only certain OSHA-specified questions can be used
No, certain OSHA-mandated questions must be included
When should a worker be referred for a follow-up evaluation based upon a questionnaire?
When the worker responds positively to one or more questions
When the worker refuses to include her height, weight or age
When the worker responds positively to one or more of the questions in 29 CFR 1910.134 Appendix C, Part A, Section 2
When the worker does not understand one or more questions
When the worker responds negatively to any OSHA-mandated question
When must an employee be fit tested?
Whenever a different faceplate is used
Whenever the employee coughs or vomits after direct exposure to a pathogen
Every 3 years
Whenever unforeseen exposure to an IDLH environment results in the employee's expiration
When his or her BMI exceeds 30
How much beard growth is permissible beneath the respirator seal?
Standard five o'clock shadow
Bradley Cooper's five o'clock shadow
1-8mm, provided no greasing agent was applied
Can an employee wear glasses or goggles when using a respirator?
Yes, if permitted by company policy
Yes, but only glasses, not goggles
No, under no circumstances
No, if wearing glasses or goggles does not provide a corrective function of at least 3.8 DVm
Yes, if they do not interfere with the respirator seal
What is the difference between supplied-air respirators (SARs) and self-contained breathing apparatuses (SCBAs)?
Supplied-air respirators have only one air tank whereas SCBAs have two or more
Self-contained apparatuses have air sources carried by the wearer; supplied-air ones do not
There is no technical difference, just different names used by competing manufacturers
Supplied-air respirators use a nitrogen-oxygen mix, whereas SCBAs use pure oxygen
What is the range of permissible oxygen percentage in compressed air for breathing?
2.5 - 5.5%
19.5 - 23.5%
50.0 - 60.0%
80.0 - 85.5%
99.5% or higher
What does IDLH stand for?
Internal Damage to Liver or Heart
Internal Department of Life and Health
Information Department for Livability and Health
Immediately Dangerous to Life or Health
Incendiary Damage to Lapidaries and Haberdashers
What does "Maximum Use Concentration" mean?
Maximum atmospheric concentration of a hazardous substance that a worker can be expected to be protected from when wearing a respirator
Maximum number of times a respirator cartridge can be used over a designated time unit as specified in 29 CFR 1910.134
The largest amount of particulate or vapor that an employee may be exposed to as averaged over an eight hour period
The concentration of a particular substance that defines its action level.
Given an ambient contamination concentration of 115ppm and a exposure limit of 2ppm, is a respirator of a suitable type with an APF of 50 acceptable?
There isn't enough data to determine that
Yes, but only in Alabama and Oregon
Yes, except in IDLH conditions
What are some of the exercises that must be included in a fit test?
Normal breathing, talking, kneeling
Normal breathing, bending over, jumping
Coughing, moving head side to side, looking up
Grimacing, moving head up and down, bending over
Jumping jacks, squats, burpies
What is fit factor?
The multiplier for a specific respirator type when computing its filtering effectiveness
The degree of plasticity, as specified in Appendix D of the regulation, one must include in calculations of respirator conformance
An estimate of the concentration of ambient substance vs. the amount inside a respirator
The number of testing exercises a worker must undertake to achieve an average degree of fitness as adjusted for gender and age
What is the difference between a qualitative fit test and a quantitative fit test?
A qualitative test relies on subjective detection of a test substance, whereas a quantitative fit test objectively determines the ratio of ambient testing substance to that inside the respirator
A qualitative fit test is a test with a passing result, whereas a quantitative test indicates neither pass nor fail
A quantitative test is only used on groups of 10 or more, whereas a qualitative test is used for smaller groups or individuals
A quantitative test requires the use of vacuum chamber, whereas a qualitative test uses ambient conditions
