Chapter 8 Flashcards
True or False: Much of the chemical protective equipment today is intended for single-use/disposable
True
When using single-use PPE, how much decon is done?
Enough for it to be safely removed, but not completely free of contamination
How often are reusable garments required to be tested?
On regular intervals and after each use
What does the acronym, meant to show potential types of harm a responder may face, TRACEMP stand for?
- T- Thermal
- R - Radiological
- A - Asphyxiating
- C - Chemical
- E - Etiological/biological
- M - Mechanical
- P - Psychogenic
What are some of the levels of protection in a hazmat emergency?
- Street clothing and normal work uniforms is the lowest level
- Firefighter turnout gear is the next level; not considered chemical protection b/c it may breakdown when exposed
- High-temperature protective equipment - best addresses unusually high thermal hazards, during short term exposures.
What makes chemical protective clothing unique?
- Designed to prevent chemicals from coming in contact with the body
- Manufacturers supply charts to assist you in choosing right clothing for incident
What are some factors that affect the chemical resistance of materials?
- Storage conditions
- Temperature
- Resistance to cuts, tears and abrasions
What are chemical-resistant materials?
Designed to inhibit or resist the passage of chemicals into and through the material by the process of penetration, permeation, or degredation
What is penetration?
The flow of a hazardous chemical through closures, such as zippers or seams
What is permeation?
Process by which a hazardous chemical moves through a material on the molecular level, occurs through material itself instead of openings in material
What is degredation?
Physical decomposition of a clothing material b/c of chemical exposure, general use, or ambient conditions.
What is vapor-protective clothing(fully encapsalating protective clothing)?
- Offers full body protection from highly toxic environments and requires wearer to use an air supplied respiratory device such as SCBA
- No skin is accessible to outside
- NFPA 1991 sets performance standards for vapor-protective garments
What is liquid splash-protective clothing?
- Designed to protect wearer from chemical splashes
- NFPA 1992 governs liquid splash-protective clothing
True or False: A safety briefing should always include a review of hand signals
True
What is the NFPA 1994: S**tandard on Protective Ensembles for First Responders to CBRN Terrorism Incidents
Developed to address the performance of protective ensembles and garments specific to WMDs
