NFPA 1971

Standard on Protective Ensembles for structural fire fighting
Must have label with manufactuers name, ID
Manufatured ID #, Lot # or Serial #
Address, country made in, materials used, foot size and cleaning precations

2

Helmet

Shed water not to protect from heat, cold or impact
Brim protects from hot water and embers reaching ears & neck

New Helmets do same, except they protect from impact, heat, cold & face shield

3

Saftey glasses & googles

Protect against approximately 85%of all eye hazards

4

Firefighter Portective coat components

Outer shell
Moisture barrier
Thermal barrier

5

Gloves

Most important protection against heat, cold, cuts, punchers & liquid absorption

6

NFPA 1977

Standard on Protective clothing & Euipment for wildland firefighting

Boots 8"-10" high

7

NFPA 1975

Standard on Station/Work uniforms for firefighters
- main part of standard garmets will not ignite, melt, drip or seperate when exposed to heat @ 500 degrees for 5 minutes

8

Care for PPE

manufactures specifications
-Helmet- Remove dirt from shell, it absorbs heat. remove chemicals, oil may soften shell
- Coats & Pants- Atleast once every 6 months

9

4 common hazardous atmosphers associated with fiers or other emergencys

- Oxygen Deficiency
- Elevated Temperatures
- Smoke
- Toxic atmospheres ( with and without fire)

10

Oxygen deficiency

-Below 18%, body increaes respitory rate
-21% normal,
-17% muscular cordination, RR increases
-12% Dizzy, H/A, rapid fatigue
-9% unconsciousness
- 6% Death within a few minutes respitory failure

11

Particular toxic gases given off at a fire very according to 4 factors

- Nature of combustibles
- Rate of heating
- Temperature of the evolved gases
- Oxygen Concentration

12

IDLH

Immediately dangerous to life and Health
(that poses a threat of exposure to airborne contaminants when that exposure is likely to cause death or immediate or delayed from such an environment)

13

(CO)

Carbon Monoxide

- Bloods hemoglobin combines with and carries oxygen in a loose chemical combinations called oxyhemoglobin
.
- (CO) combines with bloods hemoglobin & oxygen is excluded.

-More death occurs from (CO), Darker the smoke more (CO) from incomplete combustion

*S&S- H/A, Dizzy, N/V, cherry red skin
(0.05%) 500 parts per million can be dangerous
1% loss of con and death can occur

14

SCBA Limitations

Physical, medical & mental
- Limited air supply

15

SCBA TYPES

-Open circuit, Compressed air (Most Common)

- Closed Circuit (rebreather) Compressed or liquid oxygen, exhaled air stays in system for reuse.

16

4 Basic SCBA componets

- Backpack and Harness assembly
- Air Cylinder assembly
- Regulator assembly
- Face piece assembly

17

Air Cylinder sizes

-30 min 2,216 psi
-30 min 4500 psi
-45 min 3000 psi
-45min 4500psi
-60 min 4500 psi

Pressure should read within 100psi of cylinder gage

Audible alarm goes of @ 1/4 tank, FF leave immediately

18

SCBA Inspection

- After each use, weekly, monthly & annually
- Steel and Aluminum bottles must be tested every 5 years.
- Composite cylinders tested every 3 years
- Gear and SCBA has been weighed at 47lbs
- Air varys with, FF condtioning, Task Performed, Level of Training, operational enviroments, Degree of excitment

19

Emergency situation. which way do you follow hose to get out of house

- Male coupling is closet to exit
- Female is closet to fire

20

Skip Breathing

Inhale, hold breath as long as it would take to exhale, then inhale once again before exhaling.
