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.
