Temperature limit of structure gear

Answer 6

400 degrees fahrenheit (200 degrees celcius)

Question 7

Fahrenheit to Celsius conversion

Answer 7

°F =°C * 1.8000+ 32.00

Question 8

PASS

Answer 8

personal alert safety system

emit a loud alarm to alert other personnel that a FF is in danger

Question 9

PASS activates

Answer 9

when a FF is motionless for more than 30 seconds or when a FF presses the emergency button

Question 10

PASS devices assist rescuers

Answer 10

trying to locate trapped, unconscious or incapacitated FF, they are useful in:

total darkness
dense smoke
confined space

Question 11

PASS devices have at least three settings

Answer 11

off
alarming
sensing

Question 12

Must wear hearing protection when operating

Answer 12

power tools
apparatus pump
generators
PASS device test

Question 13

in some situations hearing protection is impractical and may prevent you from

Answer 13

communicating with other FF
hearing changes in fire behaviour
hearing radio transmissions
hearing calls from a trapped victim

Question 14

best protection with roadway operations

Answer 14

being visible to motorists ad working behind a barrier formed by your apparatus

Question 15

NFPA 1851 Defines four types of cleaning for PPE

Answer 15

Routine cleaning
advanced cleaning
specialized cleaning
contract cleaning

Question 16

Routine cleaning

Answer 16

does not require that the clothing be removed from service

Question 17

at an incident scene, the process for routine cleaning includes:

Answer 17

brushing off loose debris with a broom or soft bristle brush

using a gentle spray of water to rinse off debris and soil

Question 18

advance cleaning

Answer 18

those personnel should use a washing machine dedicated to cleaning protective clothing that is designed to handle heavy loads

Question 19

specialized cleaning

Answer 19

is required when clothing is contaminated with hazardous materials or body fluid that cannot be removed by routine or advance cleaning

Question 20

contract cleaning

Answer 20

typically removes accumulated grime or contaminants

Question 21

two types of respiratory protection equipment

Answer 21

atmospheric-supplying respirators (ASRs)
Air-Purifying respirators (APRs)

Question 22

respiratory hazards

Answer 22

oxygen deficiency
elevated temperatures
particulate contaminates
gases and vapors
airborne pathogens

Question 23

oxygen deficiency

Answer 23

atmosphere containing less than 19.5% oxygen

combustion is the most common cause of oxygen-deficiency atmospheres
- it consumes oxygen and produces toxic gases, which typically displaces oxygen or dilute its concentration

Question 24

elevated temperatures

Answer 24

excessive heat inhaled quickly into the lungs can cause serious decrease in BP and failure of the circulatory system inhaling heated gases can cause pulmonary edema which can cause asphyxiation

Question 25

Particulate Contaminants

Answer 25

small particles that may be suspended in the air and are harmful to the respiratory system sources of these particulates include - vehicle exhaust - chemical reactions - heated metals or metal compounds - combustion

Question 26

gases and vapors

Answer 26

gases exist at standard temperatures and pressure vapors result from temperature or pressure changes that affect a solid or liquid

Question 27

Airborne pathogens

Answer 27

are disease-causing micro-organisms suspended in the air, cause infection through inhalation or direct contact

Question 28

open-circuit SCBA

Answer 28

uses compressed air Exhaled air is vented to the outside atmosphere

Question 29

qualitative fit test (QLFT) + Quantitative fit test (QNFT)

Answer 29

provide an adequate assessment of a facepiece ability to maintain a complete seal to the face

Question 30

closed-circuit SCBA

Answer 30

uses compressed oxygen exhaled air stays within the system for reuse

Question 31

End-of-service-time-indicator (EOSTI)

Answer 31

require two alarms must be installed on all SCBAs alarm warns the user that the system is reaching the end of its air supply, typically when it reaches 33 percent of the cylinders capacity

Question 32

SCBA Wearer limitations

Answer 32

lack of physical condition lack of agility impaired balance inadequate pulmonary capacity weakened cardiovascular ability psychological limitations unique facial features

Question 33

SCBA equipment limitations

Answer 33

limited visibility decreased ability to communicate decreased endurance decreased mobility poor condition of apparatus low air cylinder pressure

Question 34

SCBA donning methods

Answer 34

over-the-head coat method donning from a seat donning from side/rear external mount

Question 35

your SCBA requires ongoing inspections and maintenance to protect you properly, you mist clean and inspect it:

Answer 35

after each use at the start of every duty shift every week

Question 36

three breathing air sources to refill depleted SCBA cylinders

Answer 36

stationary fill stations mobile fill stations firefighting breathing air replenishment system (FBARS) - system installed in high-rise buildings

Question 37

stationary fill stations

Answer 37

cascade system auto-cascade system

Question 38

storing respiratory protection equipment

Answer 38

stored for quick and easy donning protect from contamination, temperature changes and ultraviolet light

Question 39

Exit indicators

Answer 39

situations or events that signal the need to exit

Question 40

Permissible Exposure Limit (PEL)

Answer 40

the IC issues orders to change the required level of respiratory protection or withdraw from the area completely

Question 41

buddy system

Answer 41

each team member is responsible for the safety of the other member the only time a member may work alone is in a confined space where two members cannot fit (second team member remains outside monitoring the search line, ready to enter the space if need be)

Question 42

Controlled breathing

Answer 42

inhale naturally through the nose then forcefully exhale through the mouth, reducing air consumption

Question 43

Reilly emergency breathing method

Answer 43

involves inhaling deeply through the nostrils, fill lungs fully then hum while exhaling

Question 44

egress paths

Answer 44

when you exit an IDLH area, it is important to use the same path that you used to enter you should also be aware of other means of egress in case your entry route is blocked
