Study Notes

Building Construction Types

Type I Construction (Fire Resistive)
- Load bearing walls and principal structural members encased with fire resistive material.
- Provides a fire rating of two to three hours, ensuring structural elements do not contribute fuel to the fire.
Type II Construction (Noncombustible)
- Fire resistance is generally less than Type I.
- Type IIA may utilize spray-on protective products or drywall, while Type IIB typically has no fire-resistant materials, often assumed unless proven otherwise.
- Inspection areas include ceiling spaces, unfinished mechanical rooms, and roof decks to identify steel members.
Type III Construction (Ordinary)
- Features two-hour fire rated exterior load bearing masonry walls, which do not contribute fuel.
- Typically characterized by wood interior structural components.
- Commonly found in older city structures, identifiable by masonry walls and wood floors/roofs.
Type IV Construction (Heavy Timber)
- Exemplified by large exposed timber features, including rafter tails and arched roofs.
- Has two-hour fire resistance rated exterior load bearing walls but may appear similar to Type III.
- Provides additional structural mass for more extended firefighting efforts but poses risks with interior combustibles.

Utility Considerations in Emergencies

Water Meter Isolation
- Water meters have quarter turn valves to control water supply.
- An arrow indicates the on/off position; aligning holes in tabs switches to off.
- ISOLATE with caution to protect sprinkler systems.
Steam as a Utility
- Often overlooked but crucial in industrial applications for heat and power generation.
- Removal of the fuel source is vital to prevent hazardous conditions when isolating water supply.

Personal Protective Equipment (PPE) Maintenance

PPE Lifespan and Replacement
- Quartermaster will notify personnel when PPE reaches its lifespan and must be replaced.
- Outdated equipment must be returned and documented to ensure safety.
Four Components of PPE Care
- Daily inspections, cleaning, and routine or specialized maintenance.

Daily PPE Inspections

Conducted prior to duty by each firefighter for personal equipment, including SCBA.
Responsibility for completion lies with the individual firefighter and oversight from the Company Officer.

SCBA Operation Tests

PASS (Personal Alert Safety System) Testing
- Conduct tests by allowing SCBA control module to remain motionless for 20 seconds, listening for alarms.
- Verify buddy lights and LED indicators function correctly during tests and alarms.
Reset procedures include pressing the reset button and checking manual activation of the PASS alarm.

Appointments and Meetings

Customary to schedule appointments with supervisors for sensitive discussions.
Advanced notice is preferred for meetings to allow preparation.
Important to follow the chain of command unless it's the source of a problem.
Communication about meeting intentions can expedite issue resolution.

Open Door Policy

Officers and senior firefighters should foster an open-door policy.
Encourages members to approach officers with various concerns.
Helps identify and address minor issues before they escalate.

Suppression Company Style

Firefighting ensembles consist of a single piece without Velcro.
Two lettering panels required: upper panel curved, lower panel straight.
Shield, panel, and lettering colors must match department standards.
Each personal protective equipment (PPE) ensemble has an established lifespan.

PPE Maintenance Components

Daily inspection is the first component; each firefighter is responsible for their PPE and SCBA before duty.
Deficiencies must be noted and reported immediately.
Routine, advanced, and specialized cleaning are essential for PPE maintenance.
Regular maintenance and repair procedures must be followed.

Daily Inspections

Conducted individually before beginning duty shifts.
Company Officers must ensure that daily inspections are performed.
Proper functioning of SCBA involves checking the air flow and ensuring regulator safety features are locked.

PASS Operation Test

Conducted with SCBA pressurized; verifies proper operations of the warning system.
PASS pre-alarm sounds after 20 seconds of inactivity; confirms with buddy lights.
Full alarm test checks activation after 30 seconds; ensures functionality of emergency features.
Manual alarm activation and resetting procedures should be clearly understood and practiced.

SCBA Operational Checks

Low battery alerts and air supply indicators must be routinely monitored during checks.
Safe operation includes observing and responding to pressure drop warnings.
All equipment must be checked and declared ready for use before deployments.
Any operational failures require that the unit be taken out of service immediately.
