Study Notes

Wearing SCBA and "On Air"

SCBA must be used in hazardous environments, including elevated temperatures, toxic atmospheres, oxygen deficient atmospheres, confined spaces, biologically hazardous atmospheres, and areas where the Officer In Charge deems respiratory protection is required.
SCBA must be worn and "on air" at all times while inside any structure that has been on fire.
SCBA must be worn throughout overhaul and not removed, regardless of visibility or Carbon Monoxide (CO) readings.

SCBA Usage and Cylinders

60-minute (2491L) rated cylinders must be used with Level A suits, in subway stations, during decon procedures, and when deemed necessary by the Officer In Charge.
Chief Officers are not required to use SCBA while directing operations and maintaining radio communications outside the controlled area.
SCBA must be immediately returned to the apparatus after use.

SCBA Maintenance and Inspection

Persons required to wear SCBA must be free from hair interference where the facepiece seals to the skin.
SCBA may be doffed once outside the controlled area following gross decon to remove heavy contamination.
Each member of TFS must be familiar with TFS Training Note 103.2.10 – Post Use Care and Cleaning, which addresses cleaning and sanitizing of SCBA.

SCBA Cylinders and Storage

Four spare 45-minute (1868L) SCBA cylinders should be carried aboard each fire vehicle.
SCBA cylinders must be refitted with a full cylinder immediately after use, whether at an emergency scene or a training exercise.
A cylinder is considered full at a pressure of 4,050 psi (27,579 kPa) or approximately 90% of the 4,500 psi (31,026 kPa) rated capacity.
All empty air cylinders must be stored with the valve in the closed position with a minimum residual pressure of 690 kPa (100 psi) to prevent contamination.

Cylinder Maintenance and Inspection

Reusable dust caps must be in position on the cylinder when not connected to an air supply or breathing unit.
Dust caps protect cylinder valve couplings from moisture and dirt.
SCBA air cylinders that have not been used in 12 months must be slowly depressurized and refilled with compressed breathing air meeting CSA standards.
Dust caps shall be color-coded according to the year of filling (red for odd number years, blue for even number years).
MSA 3000 confined space escape cylinders shall only be refilled at the SCBA repair room. Spares are available on the North and South Air/Light.
