Respirators are PPE that protect against this:

WHAT IS... Hazards in the air. 

100

A hood or helmet that covers the head completely is also referred to as:

WHAT IS... Loose-fitting

100

True or False: Assigned Protection Factor (APF) is a numerical scale used to rate how much protection a respirator gives.

WHAT IS... True.

100

True or False: N or R filters are changed every week.

WHAT IS... False.

-They are changed every shift.

100

It is important to NOT use a respirator that has:

WHAT IS... Damage, excessive wear, has not passed a fit test, damaged cartridges, repaired with non-manufactured parts.  


200

What are the two types of respirators?

WHAT IS... 

1.Air purifying

2. Air supplying 


-Air-purifying includes one or more filters and filters out hazardous materials

-Air-supplying provides clean oxygen 

200

This creates a seal between the respirator and the face and is referred to as:

WHAT IS... Tight-fitting 

-Tight fitting masks are classified by the pressure inside the mask, negative pressure and positive pressure 

200

True or False: Respirators should be the first line of defense to offer protection.

WHAT IS... False.

-As the Hierarchy of Control suggests, respirators are the LAST line of defense that offers protection. 

200

Name three things that must be inspected before use of a respirator.

WHAT IS... 

1. Straps

2. Valves

3. Face Piece 

200

When employers are training on respirator use, what things should they include?

WHAT IS... Why it's necessary, types of hazards at workplace, reasons for various respirators, capabilities and limitations of respirators.

300

True or False: There are several different types of respirators.

WHAT IS... True. 

-There are tight-fitting, loose-fitting, air-purifying, air-supplying, negative-pressure, and positive-pressure respirators.

300

Hierarchy of Control refers to:

WHAT IS... The best way to protect a worker from hazards.

300

Choosing the right respirator depends on what three factors?

WHAT IS... 

1. Type of hazard(s)

2. Work conditions

3. How the respirator fits user 

300

How should you clean a respirator?

WHAT IS... With soap and water or antiseptic rub.

300

When storing your respirator, what should you remember to do?

WHAT IS... Protect it from high temperatures, protect from direct sunlight, put into sealed bag. 

400

True or False: All respirators provide equal protection against all types of hazards.

WHAT IS... False.

-Be aware of your respirators Assigned Protection Factor (APF) and what type of hazards you will be in contact with.

400

What is the difference between a control and a hazard?

WHAT IS... A control is intended to protect a worker from a hazard; a hazard can cause harm.

400

Tight fitting respirators are classified by what sizes?

WHAT IS... Quarter masks, half masks, full masks 

-The name suggests the amount of coverage on the face. 

400

Who created the standard of safe use of respirators?

WHO IS... American National Standard Institute (ANSI) 

-This requires that your company established a maintenance program that ensures you have a clean and well-maintained respirator.

400

The term "Breakthrough" in reference to a respirator means what?

WHAT IS... Failure of the respirator. 


-The respirator has failed, and the user is now exposed to the outside contaminated air. This can be characterized by the ability to smell contaminates. 

500

Respirators offer protection in what kind of environments?

WHAT IS... No oxygen, low oxygen, harmful particles/dust, hazardous fumes, vapors, gases, or smoke. 

500

The 4 levels of the Hierarchy of Control are:

WHAT IS... Elimination, engineering control, work practice control, PPE 


-Elimination: Getting rid of the source of the airborne particles

-Engineering control: If elimination does not work, employer will consider putting ventilation to remove particles

-Work Practice Control: Limiting the amount of time a person works in an area with hazards

-PPE: Respirators (The last line of defense) 

500

There are three types of respiratory hazards, what are they?

WHAT IS... 

1. Oxygen deficiency 

2. Toxic contaminants 

3. Biological agents 

500

What type of respirator filter can be used for multiple shifts?

WHAT IS... P-type filters 


-Change P-type filters when it becomes difficult to breathe through, becomes damaged, or soiled.

500

Assigned Protection Factor (APF) of 100 would be a higher or lower protection?

WHAT IS... Higher. 


-APF depends on the type of respirator (air-purifying or air-supplying), type of mask (loose-fitting or tight-fitting), and the type of filtering device used.
