Respiratory Protection Quiz: Masks, Filters, and Safe Use

Question 1

What should be considered before relying on a respirator to control exposure?

Accepted Answer

Whether the hazard can be eliminated or controlled effectively at source

Answer

Only whether a mask is available nearby

Answer

Only the colour of the filter

Answer

Whether a worker can tolerate the smell

Question 2

Which information is essential for selecting respiratory protection?

Accepted Answer

The contaminant, its form and concentration, oxygen conditions, task and wearer

Answer

Only the product's trade name

Answer

Only the worker's job title

Answer

Only how dusty the room looks

Question 3

What does a particulate filter protect against when correctly selected?

Accepted Answer

Specified airborne particles, rather than gases or vapours

Answer

A shortage of oxygen

Answer

Every chemical regardless of form

Answer

Every gas present in the workplace

Question 4

Can a filtering facepiece alone protect against an oxygen-deficient atmosphere?

Accepted Answer

No; it does not supply oxygen

Answer

Only if the worker takes shallow breaths

Answer

Yes, if it fits tightly

Answer

Yes, if two masks are worn

Question 5

An atmosphere's hazards and exposure cannot be identified. What should a worker do?

Accepted Answer

Avoid entry and obtain competent assessment and appropriate arrangements

Answer

Try a short entry while wearing a dust mask

Answer

Identify gases by smell

Answer

Use the highest-numbered filter without assessment

Question 6

What is the purpose of a fit test for a tight-fitting respirator?

Accepted Answer

Check whether the selected make, model and size fits the individual adequately

Answer

Measure the contaminant concentration throughout the workplace

Answer

Prove the filter removes every chemical

Answer

Replace the need for a seal check

Question 7

When should a user seal check be performed?

Accepted Answer

Each time a tight-fitting respirator is put on

Answer

Only after an exposure incident

Answer

Only when the facepiece is new

Answer

Only at the annual fit test

Question 8

Is a user seal check a substitute for a required fit test?

Accepted Answer

No; they serve different purposes

Answer

Only if a supervisor watches

Answer

Yes, if it is done carefully

Answer

Yes, for every half-mask

Question 9

Why can beard growth in the sealing area be unacceptable?

Accepted Answer

It can interfere with the face seal and allow contaminated air to leak in

Answer

It always increases filter efficiency

Answer

It makes the straps unnecessary

Answer

It affects only appearance

Question 10

A worker cannot use a tight-fitting facepiece because of facial hair. What is appropriate?

Accepted Answer

Assess suitable alternative RPE, such as an appropriate loose-fitting hood system

Answer

Tighten the straps until the face hurts

Answer

Cover the beard with ordinary tape

Answer

Assume any hood protects against all atmospheres

Question 11

Why check respirator compatibility with goggles and other PPE?

Accepted Answer

Other equipment can interfere with the face seal or function

Answer

Goggles automatically replace a facepiece

Answer

Compatibility matters only for appearance

Answer

Matching brand names guarantee compatibility

Question 12

Under US OSHA 1910.134, when is an initial medical evaluation required for required respirator use?

Accepted Answer

Before fit testing or required workplace use

Answer

Only if the respirator has powered airflow

Answer

Only after one year of use

Answer

Only after a failed fit test

Question 13

Under US OSHA 1910.134, how often is fit testing required for a tight-fitting facepiece after initial testing?

Accepted Answer

At least annually, and when specified changes require it

Answer

Only when the employee changes employer

Answer

Every five years regardless of changes

Answer

Only when the respirator visibly breaks

Question 14

A different make or size of tight-fitting respirator is issued. What should happen?

Accepted Answer

Confirm suitable fit through the required fit-testing process before use

Answer

Assume the previous fit test covers every model

Answer

Use the old straps on the new facepiece

Answer

Skip testing if the packaging looks similar

Question 15

How should gas or vapour cartridges be selected?

Accepted Answer

For the specific contaminants and assessed operating conditions

Answer

By selecting a particle filter only

Answer

By the strength of the chemical smell alone

Answer

By choosing any cartridge with a bright label

Question 16

Why is smell alone an unreliable cartridge-change method?

Accepted Answer

Some contaminants have poor warning properties and breakthrough may occur before a useful warning

Answer

Smell directly measures all exposure limits

Answer

Every harmful gas has a strong smell

Answer

A cartridge lasts indefinitely if no odour is noticed

Question 17

If a filter becomes damaged or breathing resistance increases, what should the wearer do?

Accepted Answer

Leave the hazardous area safely and follow the replacement and reporting procedure

Answer

Remove the facepiece while remaining exposed

Answer

Cut an extra hole in the filter

Answer

Continue until the shift ends

Question 18

What should happen if a wearer notices leakage or dizziness during use?

Accepted Answer

Exit safely under the emergency procedure and report the problem for assessment

Answer

Tighten the mask while continuing the hazardous task indefinitely

Answer

Remove the mask inside the exposure area

Answer

Assume symptoms prove the respirator is working

Question 19

How should a reusable respirator be cleaned?

Accepted Answer

Using the approved cleaning procedure and manufacturer-compatible methods

Answer

By spraying perfume inside it

Answer

Only by wiping the outside if the wearer changes

Answer

With any strong solvent available

Question 20

Where should a clean respirator be stored?

Accepted Answer

Protected from contamination, damage and deformation under the instructions

Answer

Inside the chemical container it protects against

Answer

Loose in a dusty toolbox

Answer

Hanging by distorted straps in direct sunlight

Question 21

Why inspect valves, straps and the facepiece before use?

Accepted Answer

Damage or missing parts can compromise fit and operation

Answer

The filter alone determines all protection

Answer

Inspection can replace all maintenance

Answer

Only the outside colour changes performance

Question 22

May filters from unrelated systems be mixed if their connectors seem to fit?

Accepted Answer

Only components approved for the specific respirator configuration should be used

Answer

Yes, connector fit proves approval

Answer

Yes, if the filters are larger

Answer

Yes, if the worker has passed a fit test

Question 23

What should training enable the wearer to do?

Accepted Answer

Understand limitations, don and check the device, use it correctly and respond to problems

Answer

Only sign the issue register

Answer

Replace all workplace assessment with personal preference

Answer

Only identify the purchase price

Question 24

What should happen when a process introduces a new airborne contaminant?

Accepted Answer

Review the exposure assessment and respiratory protection before relying on the old selection

Answer

Assume a tighter strap compensates for the change

Answer

Keep using the old filters because the task has the same name

Answer

Wait until the next scheduled stock order

Question 25

What does passing this quiz establish?

Accepted Answer

An independent knowledge check, not respirator authorisation or practical competence

Answer

Medical fitness for every respirator

Answer

A valid fit test for every facepiece

Answer

Permission to enter an unknown atmosphere
