PPE Flashcards
What does HPS stand for in Level A suits?
HPS stands for Hazard Protection Suit, offering high chemical and vapor protection for hazardous environments.
What does VPS stand for in Level A suits?
VPS stands for Vapor Protective Suit, designed for flash fire protection and chemical resistance.
What is the MT94 Multi-Threat suit?
A Level A suit that protects against chemical, biological, and thermal hazards.
What is the ONESUIT?
A fully encapsulating, lightweight chemical protection suit designed for maximum safety.
What are the steps to properly don PPE?
- Inspect all PPE for damage (suit, gloves, boots, SCBA).
- Put on inner protective garments (e.g., base layers).
- Step into the suit and pull it up to your waist.
- Put on boots and secure the suit legs over the boots.
- Don gloves and secure them under or over the suit (based on design).
- Put on SCBA, ensure proper fit, and check air supply.
- Pull the suit fully over shoulders, seal zippers, and check facepiece fit.
- Have a buddy check all seals and connections.
What are the steps to properly doff PPE?
- Decontaminate suit and gloves thoroughly.
- Remove gloves without touching the outside.
- Remove SCBA while keeping the mask on.
- Unzip the suit and step out carefully to avoid contact with outer surfaces.
- Remove inner gloves last.
- Dispose of or clean PPE per protocol.
What does breakthrough time mean in PPE?
The time it takes for a chemical to pass through PPE material, indicating its protective limits.
What are Butyl Rubber gloves used for?
Protection against gases, acids, alcohols, and highly corrosive substances.
Gloves for Protection against oils, fuels, solvents, and some chemicals.
Nitrile
Gloves for Protection against acids, oils, and greases in chemical exposure
Neoprene
What are PVC gloves used for?
Protection against water-based chemicals and low-hazard substances
Also grease, oils, some caustics
What is an APR, and when is it used?
An Air-Purifying Respirator filters harmful particles and gases but does not supply oxygen. Used when contaminants are known and oxygen is sufficient.
What is a PAPR, and when is it used?
A Powered Air-Purifying Respirator uses a battery-powered blower to filter air, suitable for extended use in low-to-moderate hazard environments.
What is an SCBA, and when is it used?
A Self-Contained Breathing Apparatus supplies its own air, used in oxygen-deficient or high-toxicity environments.
What should be included in a Level A entry checklist?
• Verify suit and SCBA functionality.
• Inspect PPE for damage.
• Review chemical compatibility of suit and gloves.
• Confirm emergency exit plan.
• Perform buddy check.
What are the responsibilities of an attendant?
• Monitor responders for safety and time limits.
• Maintain communication with the entry team.
• Manage decontamination process.
• Be prepared for emergency assistance or rescue.
What does Level A PPE protect against?
Vapors, gases, mists, and particles with full respiratory and skin protection.
What does Level B PPE protect against?
High respiratory risks with splash protection; less skin protection than Level A.
What does Level C PPE protect against?
Known chemical hazards with limited toxicity, requiring APRs and sufficient oxygen.
What is a buddy check, and why is it important?
A final verification of PPE seals, connections, and equipment by a partner to ensure safety before entry.
How do temperature extremes affect CBRNE canister performance?
High temps lower adsorption capacity; low temps condense chemicals, reducing effectiveness.
Why is SCBA duration often shorter than its rated time in hazmat environments?
Stress, exertion, and air resistance reduce usable air time.
What is the assigned protection factor APF of PAPRs compared to SCBAs?
PAPRs: 25-1000; SCBAs: 10,000 (better for IDLH).
How do Level A suits increase heat stress, and how is it mitigated?
Trapped heat and airflow restriction; mitigated with pre-cooling vests, vital checks, and time limits.
