    Study Notes

    SCBA Inspections and Maintenance

    • Annual SCBA inspections should be performed by specially trained, factory-qualified technicians.
    • Firefighters can ensure equipment reliability through frequent inspections and maintenance.

    Usage of SCBA

    • Respiratory protection is necessary in oxygen-deficient environments, such as sewer rescues.
    • Airborne pathogens may be inhaled or spread through direct contact.

    Protective Gear

    • Structural firefighting protective coats must always be worn with the outer shell, moisture barrier, and thermal barrier together.
    • Helmet faceshields provide secondary eye protection alongside SCBA facepieces.

    SCBA Features

    • The heads-up display on an SCBA facepiece indicates the amount of air remaining in the cylinder.
    • The bypass valve controls airflow if the regulator fails.

    PPE Inspections and Management

    • Following each use, PPE should be inspected for damages such as rips or tears.
    • Advanced repairs to PPE should be reported to a supervisor; damaged items should be removed from service and destroyed.

    Emergency Procedures

    • Exit indicators signal the need to evacuate from hazardous areas immediately, such as SCBA failure.
    • Firefighters must keep SCBA activated until leaving Immediately Dangerous to Life or Health (IDLH) environments.

    Fire Scene Operations

    • High-visibility vests must be worn during roadway incidents for increased visibility.
    • Mobile fill stations refill air cylinders during emergency incidents, enhancing operational efficiency.

    Cleaning and Maintenance of Gear

    • Routine cleaning of PPE can be done on-site by brushing off debris and rinsing.
    • SCBA should be stored properly to allow for easy donning without removing seat belts.

    Training and Performance

    • Regular training with SCBA helps firefighters manage psychological limitations like fear and claustrophobia.
    • Physiological factors like lung capacity are critical for SCBA performance and fireground effectiveness.

    Environmental Hazards

    • SCBA is necessary in hazardous gas events until air monitoring confirms safety.
    • Vehicle exhaust emissions are significant particulate contaminants contributing to health risks like cancer.

    General Guidelines

    • PPE inspections are mandatory before every shift and after each use.
    • Firefighting boots must adequately protect the lower leg from hazards encountered during operations.

    After-Operation Procedures

    • The SCBA cylinder valve should be closed after doffing SCBA.
    • Use the same path for exit as taken for entry when emerging from an IDLH area.

    Key Safety Considerations

    • Personal Alert Safety System (PASS) alarms activate if a firefighter is motionless for over 30 seconds.
    • Firefighters must wear PPE that conforms to NFPA standards, specifically NFPA 1971 for structural gear.### SCBA Safety Precautions
    • Check the hydrostatic test date of SCBA cylinders before refilling to ensure safe operation.
    • Rapid intervention crew universal air coupling (RIC UAC) enables air cylinder transfill from another cylinder during emergencies.

    PPE and Firefighting Equipment

    • Protective hood protects neck, ears, and face from heat, embers, and debris during firefighting.
    • Face/neck shroud is a piece of flame-resistant fabric worn under the helmet.
    • End-of-service-time indicator (EOSTI) warns users when SCBA air supply is low using an audible alarm and visual signals.

    Eye and Face Protection

    • SCBA facepiece provides primary eye protection in structural firefighting.
    • After each use, the SCBA facepiece should be cleaned with warm water and mild disinfectant.

    Respiratory Protection Guidelines

    • Surgical masks provide insufficient protection against airborne pathogens compared to SCBA.
    • Air cylinder is a SCBA component featuring a control valve and high-pressure hose.
    • Controlled breathing techniques can extend the duration of air in SCBA cylinders by slowing breathing rates.

    PPE Maintenance and Safety

    • Proper cleaning of PPE is crucial as chemicals or oils can ignite in fire conditions.
    • Always wear properly fitting protective clothing to ensure safety during firefighting operations.

    Health and Safety Considerations

    • SCBA protects against asphyxiation, a risk from inhaling heated gases.
    • Wearing respiratory protection is essential to mitigate health hazards from smoke and combustion products.
    • If experiencing symptoms of oxygen deficiency, report and evacuate the area immediately for safety.

    Types of Respiratory Protection

    • Atmosphere-supplying respirator (ASR) is the primary type of respiratory protection used in fire service.
