Chapter 5 - PPE

Question 1

Standards for PPE NFPA

Answer 1

1971 - PPE design and construction
1851 - PPE care and maintenance
1977 - Wildland fire fighting protective clothing
1975 - Station/work uniforms
1981 - SCBA
1982 - PASS devices

Question 2

Usual PPE temperature limit

Answer 2

400F (200C)

Question 3

Helmet face shield

Answer 3

Face shields alone do not provide adequate protection from flying particles or splashes and should be used in conjunction with a primary form of eye protection. NFPA 1500 requires use of goggles or other eye protection.

Question 4

Protective coat

Answer 4

Outer shell, moisture barrier and thermal barrier.

Question 5

DRD

Answer 5

Drag rescue device. Harness and hand loop at the back of the neck that enables a rescuer to grab and drag a downed FF

Question 6

PASS

Answer 6

Alarm must be at least 95 decibels (dBA) and must go off continuously for at least 1 hour.

Question 7

Wildland PPE

Answer 7

Not designed, certified or intended for interior structural fire fighting.

Question 8

Roadway incidents

Answer 8

Required to wear high visibility vests.

Question 9

Overlap of coat and trousers

Answer 9

Minimum of 2 inches (50mm) at the waist when you bend over at 90 degrees.

Question 10

Thermal burns

Answer 10

May occur at compression points where the garment layers are pressed together, such as under the SCBA shoulder harness, along sleeves in contact with hose lines, and on knees when kneeling on hot debris and embers. Thermal environment will heat exterior PPE resulting in thermal saturation that can cause contact burns.

Question 11

Cleaning PPE

Answer 11

Routine cleaning
Advanced cleaning
Specialized cleaning
Contract cleaning

Question 12

Atmosphere supplying respirators (ASRs)

Answer 12

SCBA. Breathable air when working in oxygen deficient, toxic, or gas filled atmospheres.

Question 13

Air purifying respirators (APRs)

Answer 13

Only filter particulates out of the surrounding air.

Question 14

Oxygen deficient atmosphere

Answer 14

Containing less than 19.5%. If it falls below 18%, human body increases respiratory rate. Combustion is most common cause of oxygen deficient atmospheres.

Question 15

Breathing heated air

Answer 15

Damage respiratory tract. Can be worse if air is moist. Inhaling heated gases can cause pulmonary edema which can cause asphyxiation.

Question 16

Fire gases and vapours

Answer 16

CO
CO2
Hydrogen cyanide (HCN)
Hydrogen sulfide
Hydrogen chloride
Phosgene
Ammonia
Nitrous gases
Sulfure dioxide
Formaldehyde

Question 17

Common nonfire gas and vapour

Answer 17

Ammonia - AC units and cooling systems, chilling systems for hockey rinks, agricultural applications
Chlorine - water treatment facilities, water parks and swimming pools
Pesticides - commercial outlets, farms, nurseries, and residences.

Question 18

HEPA filters

Answer 18

High efficiency particulate aire filters. Protection against airborne pathogens.

Question 19

SCBA

Answer 19

Open circuit operation

Question 20

Breathing air cylinder capacities

Answer 20

45 minute - 4500 psi - 1870L
60 minute - 4500 psi - 2460L

Question 21

EOSTI

Answer 21

End of service time indicator. Alarms that warn the user that the system is reaching the end of its air supply.

Question 22

Donning from a backup mount

Answer 22

Provides quick access to the SCBA.

Question 23

SCBA inspection and care

Answer 23

Clean and inspect; after each use, at the start of every duty shift, and every week.

Question 24

Refilling SCBA cylinders

Answer 24

Stationary fill systems, mobile systems, and FBARS (firefighter breathing air replenishment systems, systems installed in high rise buildings).

Question 25

Stationary fill systems

Answer 25

Breathing air cascade fill system - Compressor unit with air line to cascade air cylinders with air line to fill station.
Air compressor fill system - Compressor unit air line to fill station.
