Study Notes
CO Meter Issuance and Responsibility
- Every suppression, rescue, and battalion unit will receive a Carbon Monoxide (CO) meter.
- Unit Officers-in-Charge (OIC) are responsible for the meter's presence and calibration.
- The CO meter has a fixed operational life of five years and is issued activated, requiring no battery replacement.
Situations for CO Meter Usage
- Meter is used in the apparatus, during non-fire emergencies (e.g., EMS responses, public assists), and post-fire to assess CO levels.
- The CO meter should not be employed during active fire suppression or investigation operations.
Meter Storage Guidelines
- Suppression and rescue unit meters are kept attached to the EPCR tablet's strap.
- Battalion chief unit meters are stored in the passenger cab, secured to the Mobile Computer Unit handle.
Calibration and CO Properties
- Calibration involves testing sensor accuracy by exposing the meter to a test gas.
- Carbon Monoxide (CO) is colorless, odorless, tasteless, and highly toxic, produced from incomplete combustion of fuels.
- CO binds with hemoglobin in blood, hindering oxygen transport and potentially causing tissue hypoxia.
Signs and Symptoms of CO Poisoning
- Common symptoms include headache, nausea, vomiting, dizziness, fatigue, and weakness.
General Guidelines for CO Detection
- If CO is detected:
- In apparatus: Shut down the unit, evacuate personnel, notify relevant officials, and call a HazMat unit.
- During non-fire calls: Evacuate occupants from affected areas, notify the Fire Alarm Office, and secure the scene.
- Post-fire: Use the meter to determine CO presence; readings must be documented, and occupancy warnings issued.
Maintenance of the CO Meter
- After high alarm activation, the meter should be placed in an open environment until readings return to zero, avoiding exposure to exhaust.
- Keep meter cover clean with a damp cloth; do not use solvents or cleaners.
- Avoid storing the meter near silicone lubricants or chemicals to prevent sensor saturation.
Alarm Notification Procedures
- Alarms activate when gas concentrations exceed pre-set limits, remaining on until acceptable levels are achieved.
- Low Alarm: One beep, flash, and vibration per second at 25 parts per million (ppm).
- High Alarm: Two beeps, flashes, and vibrations per second at 100 ppm.
Replacement Procedures
- For meter replacement, complete an online HazMat Service Request.
- If the meter is lost, damaged, or stolen, submit a Lost or Damaged Property Form and obtain a police report and investigative memorandum from the Battalion Chief.
