Q

Vapor protective ensembles are components of ensembles to be used at chemical and biological hazmat/wmd incidents.

A

Vapor protective ensembles

23
Q

Vapor protective clothing - Gas tight chemical protective clothing designed to meet NFPA 1991.

A

Vapor protective clothing

24
Q

All emergency response organizations that routinely use CPC must establish a written Chemical protective clothing program and respiratory protection management program.

A

respiratory protection management program

25
Q

CPC’s effectiveness can be reduced by three actions: permeation, degradation, and penetration

A

permeation,

26
Q

Permeation - Is a process that occurs when a chemical passes through a fabric on a molecular level.

A

Permeation

27
Q

Chemical degradation - Occurs when the characteristics of a material are altered through contact with chemical substances.

A

Chemical degradation

28
Q

Penetration - Is a process that occurs when a hazardous material enters an opening or a puncture in a protective material.

A

Penetration

29
Q

Decontamination will not stop permeation from occurring.

A

permeation

30
Q

Once the IAP is developed, the site safety plan will spell out ppe requirements for tasks performed at the incident.

A

site safety plan

31
Q

Agencies responsible for responding to CBR incidents should select equipment in accordance with regulatory standard for response to such incidents, such as NIOSH standards and NFPA 1994.

A

1994

32
Q

The ensemble worn at an incident will vary depending on the mission of the responder.

A

mission of the responder

33
Q

medical monitoring is required when environmental factors put you at risk

A

medical monitoring

34
Q

Heat stroke occurs when the body’s system of temp regulation fails and body temp rises to critical levels.

A

Heat stroke

35
Q

The elevated metabolic temps caused by a combination of workload and environmental heat load, both which contribute to heat stroke, are also highly variable and difficult to predict.

A

workload , heat load

36
Q

Drinking 7 ounces of fluid every 15 to 20 minutes is better than drinking large quantities once an hour.

A

7 , 15 to 20

37
Q

Wind chill, a combination of temperature and velocity, is a crucial factor to evaluate when working outside.

A

temperature and velocity

38
Q

For example, when the actual air temp of the wind is 40F and its velocity is 35 mph, the exposed skin experiences conditions equivalent to the still air temp of 11 F.

A

11*F

39
Q

Responders should operate within their accountability systems, and know their evacuation and escape procedures.

A

accountability systems

40
Q

A safety briefing will be conducted before responders enter the hot zone.

A

safety briefing

41
Q

After using ppe at an incident, fill out any associated reports or documentation as required by the AHJ.

A

AHJ

42
Q

A cylinder’s service pressure and rating are not a true indication of the overall work time.

A

work time

43
Q

Contamination can be defined as a condition of impurity resulting from contact or mixture with a foreign substance.

A

Contamination

44
Q

Communication capabilities are required for all levels of personal protection.

A

Communication capabilities

45
Q

Should responders lose radio communication or operate in an atmosphere not allowing radio communications, a backup system must be part of the operational plan.

A

operational plan

46
Q

In addition to entry team signals, include an emergency evacuation signal for all responders in the incident action plan.

A

incident action plan

47
Q

Conduct a mission briefing before the donning process to ensure that all members are attentive and there are no distractions.

A

mission briefing

48
Q

The mission briefing should include the specifics of the mission such as the IAP and site safety plan.

A

site safety plan

49
Q

Once the donning process has begun, the donning supervisor should prepare both the entry team and the backup team at the same rate.

A

donning supervisor

50
Q

The safety officer should perform a final check of all equipment and closures before the teams are allowed to enter the hazard area.

A

safety officer

51
Q

The personnel assisting in the doffing procedures should watch for signs and symptoms of heat stress.

A

heat stress

52
Q

The last item removed from the entry personnel should be the respirator facepiece.

A

respirator facepiece

53
Q

Operational inspections of respiratory protection equipment occur after each use, daily or weekly, monthly, and annually.
