Degradation is the physical destruction or decomposition of a clothing material owing to _______, _______ or _________.

Chemical exposure. General use. Ambient conditions.

Degradation | Evidenced by visible signs such as ______, ______, ______, ________ or _________.

``` Charring. Shrinking. Swelling. Color changes. Dissolving. ```

Fabric degradation is possible:

Chemicals are so aggressive. | When suit fabric is a poor match for the suspect substance

Chemical-protective clothing can be CONSTRUCTED as a _______ or _________ garment. Level A protection is ALMOST always built as an __________. Multi-piece garments are found as ____________.

Single. Multi-piece. Encapsulated one-piece (not "single-piece"). Level B and C.

CPC - both single- and multi-piece- are classified into two major categories: __________ and ___________ clothing.

Vapor-protective. | Liquid splash-protective

Fully encapsulating clothing OFFERS full body protection from highly toxic environments and requires wearer to use an air-supplied respiratory device such as SCBA.

Vapor-protective clothing

Reusable garments are required to be tested __________ and ___________.

Regular intervals. | After each use

Fully encapsulating garment that completely ENVELOPS both the wearer and the respiratory protection, gloves, boots, and communications equipment. SCBA OR SAR

Level A ensemble

Number of tests against vapor-protective and liquid splash-protective clothing

VP - **permeation** 21 standard chemicals, "several" toxic industrial chemicals and 2 chemical weapons. LSP - **penetration** 5 chemicals (no gases)

Everyone should know the basic communication "_________" position to ensure that in the event of an emergency (loss of breathing air, SCBA cylinder failure or acute illness and injury) anyone having visual contact with the responders will quickly understand that a problem is occurring.

NFPA 1994 covers 3 classes of equipment: Class 2, 3 and 4. HAZWOPER classify ensemble levels as A, B, C and D. The main difference between their system and NFPA 1994 classification is that NFPA 1994 covers __________________ and _____________________.

The performance of the garment AND factors in the performance of the respiratory system

1994 covers class 2, 3 and 4. They are?

2-liquid splash with SCBA. 3-liquid splash with APR. 4-particles and liquid-borne viral.

HAZWOPER states all employees engaged in emergency response who are exposed to HAZARDOUS SUBSTANCES shall wear __________.

A positive pressure SCBA

_____ protection, when worn in accordance with NFPA 1991, will protect the wearer against a "transient episode of flash fire".

Level A

Best level of protection is the one that is the most appropriate for _______ and _______.

The hazard. | The mission

Last piece of equipment taken off when doffing level A and B? Last piece for C?

Inner gloves. | Helmet.

Worn when the type and atmospheric concentration of identified substances require a high level of respiratory protection BUT less skin protection.

Level B

_______ is minimum level of protection to be worn when operating in an unknown environment.

Level B

The workhorse of hazardous material response

Level B

Level B ensemble provides little or no flash fire protection, thus it should be viewed in the same manner as ________ equipment when it comes to THERMAL protection.

Level A

_______ is minimum level of protection to be worn when operating in an unknown environment.

Level B

____________ is appropriate when significant skin and eye exposure is unlikely.

Level C

Level C is appropriate when the type of __________ is known, __________ is measured, and _______________ are met.

Airborne contamination. Concentration. Criteria for using an APR.

Many law enforcement agencies have provided their officers with _________ ensembles to be carried in the trunk of their patrol car.

Level C

Primary role of medical monitoring station is to evaluate the medical status of: (3)

Entry. Backup. Decon.

Cooling technologies not limited to: (4)

Air, ice and water cooled vests. | Phase-change cooling technologies

Typical chemical-protective equipment performance requirements include tests for: (4)

Durability. Barrier integrity after flex and abrasion challenges. Cold-temperature flex. Flammability

User of any garment that meets NFPA standard can rest assured that the garment will withstand:

Reasonable insults from MOST mechanical-type hazards

Working in PPE is a hazardous proposition on two different levels:

Simply by wearing PPE, responder acknowledges some degree of danger exists. Wearing PPE puts an inherent stress on the responder, separate from stress from environment

Primary role of medical monitoring station is to evaluate the medical status of: (3)

Entry. Backup. Decon.

Cooling technologies not limited to: (4)

Air, ice and water cooled vests. | Phase-change cooling technologies

First level of cooling the BODY would NATURALLY employ. Heat is drawn away - by convection. Systems lightweight and provide LONG-TERM cooling benefits. Mobility is limited

Forced-air cooling

COMMONLY USED due to low COST, UMLIMITED portability and unlimited "recharging". Vest-like in design, worn around torso. Vest absorbs heat. BULKIER and heavier. May cause discomfort. May actually fool the body into thinking it's cold

Ice-cooled or gel-packed vests

Pumping ice-chilled liquids from a RESREVOIR, through a series of TUBES within a vest-like garment. Mobility may be limited. Some systems incorporate BATTERY-operated unit. Add'l weight may increase workload

Fluid-chilled systems

Similar fashion to ice- or gel-packed vests Main difference is that temperature of material is chilled to approx. 60F Fabric of vest is designed to wick perspiration away Packs typically recharge more quickly than others

Phase-change cooling

Approximately _____ of all body heat is generated by the organs and muscles located in your torso.

90%

______ is a common problem when wearing chemical-protective equipment, especially encapsulated suits.

Claustrophobia | *TRACEMP-Psychogenic*
