Study Notes

Personal Protective Equipment (PPE)

Essential for firefighter safety: Provides full body coverage and protection from various hazards
Regular maintenance: Must be cleaned, maintained, and inspected regularly

Structural Firefighting Ensemble

Designed for high-temperature and toxic gas environments
Worn with Self-Contained Breathing Apparatus (SCBA)
Key components:
- Helmet: Meets NFPA 1971 Standard, provides impact protection, color-coded for rank and function
- Protective Hood: Covers exposed skin, flame-resistant material, worn under helmet
- Turnout Coat: Three layers: outer shell, moisture barrier, thermal barrier, secure double seal
- Bunker Pants: Match turnout coat, three-layer protection, large for quick donning and movement
- Boots: Rubber or leather, meet NFPA 1971, water-repellent, flame-resistant, thermal protection
- Gloves: Protect from heat, liquids, vapors, cuts, penetration, heat-resistant leather
- Personal Alert Safety System (PASS): Electronic device that sounds an alarm if the firefighter is motionless or activates it. Can be separate or integrated into the SCBA unit
- Additional PPE: Approved goggles, intercom system, earplugs, hand light, radio, reflective vest, drag rescue device

### Limitations of Structural Firefighting Ensemble

Requires energy and strength
Retains body heat and perspiration
Limits mobility and range of motion
Decreases normal sensory abilities

Work Uniforms

Nylon or polyester clothing may melt
Synthetic fibers are resistant to high temperatures

Donning and Doffing PPE

Done in a specific order for maximum protection
To doff PPE, reverse the donning procedure

Care of PPE

Regular condition checks are necessary
Repair worn or damaged PPE immediately
Clean PPE when necessary: bad soiling, chemical exposure, or hazardous material exposure
Follow the manufacturer’s instructions

Specialized Protective Clothing

Vehicle Extrication: Lighter and more flexible than structural firefighting PPE, latex gloves and eye protection are recommended for patient treatment
Wildland Fires: Meets NFPA 1977, fire-resistant materials, designed for comfort and maneuverability, helmet, eye protection, gloves and boots specifically designed for comfort and sure footing

Respiratory Protection

Interior atmosphere of a burning building is immediately dangerous to life and health (IDLH)
Firefighters must be proficient in using SCBA before engaging in interior fire-suppression activities

Respiratory Hazards of Fires: Smoke

Three major components:
- Smoke particles
- Smoke vapors
- Toxic gases: carbon monoxide, hydrogen cyanide, phosgene

Respiratory Hazards of Fires: Oxygen Deficiency

Occurs when fire consumes available oxygen or produces gases that displace oxygen
Can lead to disorientation, muscle control issues, and irrational thinking

Respiratory Hazards of Fires: Increased Temperature

Inhaling superheated gases can cause severe respiratory burns

Other Toxic Environments

Firefighters may encounter toxic gases or oxygen-deficient environments in:
- Hazardous materials releases
- Confined-space or below-grade structures

Conditions that Require Respiratory Protection

SCBA must be used:
- In enclosed areas with smoke
- During overhaul until air is tested
- Whenever toxic gases or oxygen-deficient atmospheres are possible
Golden rule: Always assume that the atmosphere is hazardous!

Types of Breathing Apparatus

Open-circuit SCBA: Used for structural firefighting, compressed air tank provides supply, exhaled air released into the atmosphere
Closed-circuit SCBA: Used for extended operations, air passes through a mechanism that removes carbon dioxide and adds oxygen within a closed system
Supplied-air respirator: Uses a hose line connected to a breathing-air compressor or compressed air cylinders, sometimes used for specialized operations

SCBA Standards and Regulations

NIOSH: Sets design, testing, and certification requirements for SCBA
OSHA and state agencies: Responsible for establishing and enforcing respiratory protection regulations
NFPA standards related to SCBA:
- NFPA 1500: Basic requirements
- NFPA 1404: Requirements for SCBA training
- NFPA 1981: Requirements for design, performance, testing, and certification of open-circuit SCBA

Limitations of SCBA

Air cylinder capacity: Use is limited by the amount of air, factors to consider:
- Time and effort to reach destination
- Available air upon reaching destination
- Time to complete task
- Time to reach a safe area
Added weight and bulk: Decreases flexibility and mobility
Face piece: Limits visibility
Communication and hearing: Face piece may affect communication and hearing abilities

Physical Limitations of the User

Moving with the extra weight of SCBA and PPE requires additional energy, increasing air consumption and body temperature

Psychological Limitations of the User

Breathing through an SCBA can be stressful due to foreign environment
Firefighters must adapt to these stressful conditions

Components of SCBA

Backpack: Frame for mounting other SCBA parts
Harness: Straps and fasteners to attach the SCBA to the firefighter
Air cylinder: Holds breathing air, equipped with a hand-operated shut-off valve, pressure gauge indicates cylinder pressure
Regulator assembly: Controls air flow, some have dual-path pressure reducer, needs cylinder valve opening, SCBA donning, and face piece attachment, contains a pressure gauge (second heads-up display required), includes end-of-service-time-indicator (EOSTI) or low-air alarm (NFPA requirement), some include PASS device, equipped with rapid intervention crew/company universal air connection (RIC UAC)
Face piece assembly: Delivers breathing air, consists of face mask, exhalation valve, regulator, covers entire face, requires annual fit test

Pathway of Air Through an SCBA

Air passes through the cylinder shut-off valve into the high-pressure hose to the regulator.
The regulator sends air to the face piece and the user.
Exhaled air returns to the face piece and is exhausted through the exhalation valve.

Skip-Breathing Technique

Conserves air: take a short breath, hold, take another short breath, relax and exhale fully.
Each breath should take 5 seconds.

Mounting Breathing Apparatus

SCBA should be located for quick donning:
- Seat-mounted brackets
- Compartment-mounted brackets
- Exterior-mounted SCBA

Donning SCBA

Before donning:
- Air cylinder at 90% pressure
- Donning/doffing switch activated
- Open the cylinder and listen for alarm
- Check pressure gauges
- Check harness straps for full extension
- Check valve positions

Donning SCBA From an Apparatus Seat Mount

Don all protective clothing
Place arms through shoulder straps

Inspection of SCBA

Identify damaged or needing repair parts
Operational testing: checks SCBA functioning after each use, beginning of shift, or on schedule
Annual inspection: required for every SCBA, performed by a certified manufacturer's representative or trained and certified personnel

Servicing SCBA Cylinders

Cylinders are visually inspected during daily and monthly inspections
Federal law requires periodic hydrostatic testing and limits the number of years a cylinder can be used.

Replacing SCBA Cylinders

One firefighter can doff the SCBA to replace the air cylinder.
Two firefighters can change cylinders without removing the SCBA.
Firefighters should be able to change cylinders in the dark while wearing gloves.

Refilling SCBA Cylinders

Compressors and cascade systems are used to refill SCBA cylinders.
Proper training is required to fill SCBA cylinders.

Cleaning and Sanitizing SCBA

Follow the manufacturer’s instructions.
Rinse the unit with clean water.
Clean the harness assembly and cylinder with mild soap and water.
Clean the face pieces and regulators with mild soap and water or a disinfectant solution.

Summary

Personal protective equipment is crucial for firefighters.
Structural firefighting PPE enables firefighters to operate in burning buildings, high temperatures, and toxic gas environments.
PPE includes a bunker coat, pants, helmet, protective hood, boots, SCBA, PASS, and additional equipment.
Structural PPE adds weight.
Firefighters should be able to don PPE within 1 minute.
PPE needs regular checks and cleanliness.
Gloves and coveralls or jumpsuits are used during vehicle extraction.
PPE for wildland fires incorporates a fire-resistant jacket and pants, helmet, eye protection, and pigskin or leather gloves.
The two main types of SCBA are open-circuit and closed-circuit devices.
SCBA limits the air supply in the cylinder.
Breathing through an SCBA is different from normal breathing and can be stressful.
SCBA consists of a backpack, harness, air cylinder assembly, regulator assembly, and face piece assembly.
Air flow through SCBA follows a specific pathway.
Skip-breathing conserves air.
SCBA requires regular checks.
