Maple Valley Fire Department
1. All Fire Department Personnel shall wear SCBA when operating in any of the following atmospheres.
a. Any IDLH atmosphere.
b. An oxygen rich or deficient atmosphere.
(Under 19.5%, Over 23.5% oxygen)
c. An atmosphere of particulate, gas or vapor contaminants. ie: asbestos, CO, HCN
d. In any permit-required confined space that has not been tested and monitored to establish respiratory safety.
e. Any possible signs of WMD event.
Gross Deconshall be performed
prior to removal of face piece.
2. SCBA shall be used by all personnel who enter into hazardous atmospheres during structural firefighting activities or other IDLH or potential IDLH atmospheres, including:
a. In an active fire area.
b. Directly above a fire area.
c. Directly under the active area.
d. In potential explosive or fire area, including gas leaks or fuel spills.
e. Where products of combustion are visible in an atmosphere, including vehicle fires and dumpster fires.
f. Where invisible contaminants are present or suspected. This includes the overhaul stage of a fire.
g. Where toxic products are present, suspected of being present, or may be released without prior warning.
h. In an active chemical spill area where the chemical presents an inhalation hazard.
SCBA use is mandatory if you are working in atmospheres where CO, HCN and other toxic gasses are suspected to be above safe levels.
Fiberglass dust and other particles in the air, or suspected in the air, require SCBA use.
Employees shall wear respiratory protection when transporting an individual with suspected or confirmed infectious tuberculosis or meningococcal bacterium or other infectious air borne illness, (H5N1, H1N1) even if individual is masked.
Neither P100 nor N95 may be used for overhaul.
WAC 296-842-22020 states: Prior to each use the unit must be checked to ensure that a proper seal is achieved. A 10 second negative pressure seal check is required.
The best way to do this is with your 2nd stage regulator.
New for Maple Valley
Hazardous atmospheres members may be exposed to during Routine and Emergency Operations:
Physical condition– maximize work effort
Agility– restrictive movements
Facial Features– seal issues
Contact Lenses– otherwise glasses inserts are provided
Respiratory– any smokers?
Mental– training, confidence, “cool”
Limited visibility– peripheral vision is reduced, fogging
Communication– failures of lapel mics, amplifiers not turned on.
Weight– 25-35 extra pounds
Mobility– backpack and straps reduce ability to move freely
Equipment malfunction– Know what to do if your equipment suddenly malfunctions
Cold Weather– water spray from fire fighting activities can cause SCBA to freeze up and not function properly.
Chemicals– while the SCBA protects your respiratory system, many chemicals are absorbed through your skin. DECON.
Extreme Heat– Elevated temperatures such as flashover may damage SCBA beyond use.

Nobody wants to accept liability!
We’re talking about IMPROPERLY functioning SCBAs!
ALMOST ALL PACK FAILURES WILL OCCUR AS THE BOTTLE IS TURNED ON! Don’t let this happen at the front door!
That’s EMERGENCY OPS!
**NOTE** Vibralert will not function if this happens
If the MMR regulator won’t control it, USE THE BOTTLE VALVE! DON’T WASTE AIR!
**Remember, if the regulators do not provide air, the quick fill option will not do any good**
GET OUT FAST!! And Get Out ALIVE!!
