Q

What conditions warrant atmospheric monitoring?

A
  • When SCBA removal is requested at fire post ventilation
  • Personnel found working inside w/o SCBA

Q

How should PPE for Haz-Mats be determined?

A

By the IC based on info available and at his discretion

20
Q

What should all confine space operations begin with?

A

Air monitoring

21
Q

When should monitor readings be recorded on CS?

A

Before vent, after the start of vent, and during rescue operation.

22
Q

Any rise or change in the readings for any alarm from the air monitor shall be immediately reported to the ?

A

IC

23
Q

What should be used to allow access to multiple levels of confined space?

A

A 4 gas monitor with a pump and pick up tube

24
Q

Where shall proper PPE be worn on confined space?

A

In immediate area of entrance and ventilation exit port

25
Q

What is the action level in order to operate without SCBA in an environment where HCN is present?

A

4.7 ppm

26
Q

What is the Short Term Exposure Limit (STEL) for HCN as recommended by NIOSH?

A

4.7 ppm

27
Q

What is the definition of short term exposure limit (STEL) as defined by NIOSH?

A

a 15-minute time weighted average (TWA) exposure that should not be exceeded at any time during a workday

28
Q

What is the action level for CO?

A

35 ppm

29
Q

What should personnel do prior to drinking and eating in rehab or back at station?

A

Wash your hands/practice good hygiene

30
Q

Who is responsible for reporting an significant exposures during a structure fire?

A

Reporting officer

31
Q

What information should be provided in the narrative when reporting a significant exposure?

A 
HCN and CO levels during the time of operation
Areas monitored
How long personnel operated
Those personnel that operated
Specifics concerning the call
32
Q

What should be done anytime personnel are operating outside the safe range without SCBA?

A

A notation is to be made in the report under the Fire personnel Casualty section

33
Q

Who calibrates and when should the monitors be calibrated?

A

The engineer (or acting engineer) assigned to the unit on the 15th of every month.

34
Q

What should the engineer check during calibration?

A

the battery state, span and/or calibrate the devices

35
Q

Whos responsibility is it that calibration is taken care of?

A

The Lieutenant

36
Q

How are meters to be calibrated?

A

Bump tested according to manufacturer recommendations

37
Q

What will need to happen to meters if they are exposed to high concentration and register “out of range”?

A

The meter will need to be bump tested at a minimum to insure proper operation

38
Q

How do we keep track of all spanning and calibration?

A

Control log that is to be completed monthly

39
Q

What three indicators are to be used to determine if a person has been exposed to HCN?

A

Exposed to fire or smoke in an enclosed area
Soot found around the mouth and nose
Altered mental status

40
Q

How long is the half life of HCN

A

One hour

41
Q

What medical attention should be included due to HCN short half life?

A

Blood work and HCN testing

42
Q

What should destitnation hospital be advised of when transporting a FF with possible HCN?

A

That the FF was operating in a known hazardous environment containing hydrogen cyanide

43
Q

What are some acute exposure symptoms of HCN?

A

weakness, headache, confusion, vertigo, fatigue, anxiety, dyspnea, and occasionally nausea and vomiting

44
Q

What happens to the respiratory rate when exposed to HCN?

A

Usually increased initially and at later stages becomes slow and gasping.

45
Q

What does cyanosis in HCN usually indicate?

A

That respiration has either ceased or has been inadequate for a few minutes.

46
Q

What happens if large amounts of cyanide are absorbed?

A

collapse almost instantaneous, unconsciousness: often with convulsions, is followed almost immediately by death
