Haz Mat #4 & Add #1 - Carbon Monoxide & GasAlert Extreme Carbon Monoxide (CO) Monitor

Question 1

If the CO in the atmosphere EXCEEDS 35 PPM, how does the monitor react?

Answer 1

1. 2 A visual and low audible warning with a SLOW vibration is given if the concentration of CO in the atmosphere EXCEEDS 35 PPM (36,37,38,etc.).
   * a SLOW modulating tone every 1 second
   * w/ SLOW flashing red lights every 1 second
   * a SLOW vibration every 1 second

Question 2

If the CO in the atmosphere EXCEEDS 100 PPM, how does the monitor react?

Answer 2

1. 3 A visual and low audible warning with a FAST vibration is given if the concentration of CO in the atmosphere EXCEEDS 100 PPM (101,102,103,etc.).
   * a FAST modulating tone every 1/2 second
   * w/ FAST flashing red lights every 1/2 second
   * a FAST vibration every 1/2 second
   * *When the CO concentration falls below 100 PPM (99,98,97,etc.) the monitor will go into low alarm.

Question 3

If the CO Monitor does not operate for any reason, who does the OOD notify?

Answer 3

3.4 If the monitor does not operate for any reason (low battery, malfunction, etc.) the OOD shall notify their Battalion and arrange for an exchange (PREPARE RT-2).

Question 4

The CO Monitor low battery alarm consists of what?

Answer 4

3. 5 The LOW battery alarm consists of
   * 1 beep (every 5 seconds)
   * 1 flash (every 5 seconds)
   * 1 quick vibration (every 1 minute)
   * a low battery icon will appear on the display

Question 5

How shall a company mark the CO Monitor for identification purposes?

Answer 5

3.6 If marking the monitor with company I/D, DO NOT etch or use marker! (sticker/tape are acceptable).

Question 6

Describe the properties of Carbon Monoxide.

Answer 6

2. 4
   * It is a flammable gas
   * It has an auto ignition temperature of 1128 degrees F.
   * LEL - 12.5%
   * UEL - 74%
   * Slightly lighter than air (.968)

Question 7

Who has been issued CO meters?

Answer 7

2.6 All ladder companies have been issued CO Meters.

Question 8

T or F - CO is about 210 more times attracted to hemoglobin than O2.

Answer 8

True - CO is about 210 more times attracted to hemoglobin than O2.

Question 9

T or F - To reverse the buildup of COHb in the body, OVER 200 parts of oxygen are required to replace one part of CO.

Answer 9

True - OVER 200 parts of O2 are required to replace one part of CO.

Question 10

Describe the symptoms of CO poisoning.

Answer 10

LOW level - Can mimic flu symptoms, headache (mild/severe), fatigue, nausea,dizziness, confusion, irritability.

• MEDIUM level - vomiting, drowsiness, loss of consciousness
• HIGH level - seizure, coma, permanent brain damage, death.

Question 11

When using the CO Meter where is the INITIAL reading taken?

Answer 11

4.1.3 - Using a CO Meter, take an INITIAL reading at the FRONT DOOR of premises, then continue investigation to find source of CO in premises.

Question 12

T or F - If no one exhibits any symptoms of CO poisoning, evacuation is not necessary, UNLESS a level of OVER 9 PPM (10,11,12,etc.) is recorded by the meter.

Answer 12

4.1.4 - True

Question 13

Define a CO Incident

Answer 13

4. 2.1 - No occupants are symptomatic and meter readings of 9 PPM or less.
   * No evacuation required at an incident.

Question 14

Define a CO Emergency

Answer 14

4. 2.2 - Occupants are symptomatic or meter readings GREATER THAN 9 PPM (10,11,12,etc.).
5. 4 - Readings greater than 9 PPM but LESS than 100 PPM (99,98,97,etc.)
   * RECOMMEND that all persons leave the affected area and begin ventilation.
6. 5 - Readings of 100 PPM and GREATER (100,101,102,etc.)
   * BEGIN evacuation

Question 15

T or F - SCBA shall be WORN at all CO investigations and USED at all CO emergencies.

Answer 15

4.2.5 - True

Question 16

Carbon Monoxide radio code

Answer 16

5.1.1
10-38 - Carbon Monoxide Response
*Any type of carbon monoxide response
CODE 1 - Detector activation: Carbon monoxide investigation (low battery, defective detector, unwarranted alarm, etc.)
Code 2 - Detector Activation - CO INCIDENT (reading of 1-9 PPM)
CODE 3 - Detector Activation - CO EMERGENCY (reading of GREATER THAN 9 PPM)
CODE 4 - No detector activation: CO Incident or Emergency (specify) e.g.; No detector present in affected area, detector PRESENT in affected area, but DID NOT activate.
