Vehicle Isolation Quiz

Study Notes

Every mine must maintain a mine rescue team to ensure the safety of workers and property on mine sites.
The mine rescue team must be trained to respond to incidents at surface and underground mining operations.

Upon arriving at the incident scene, stage response vehicles at a safe distance to avoid exposure to electrical hazards.
Isolate the vehicle for a period of time at a safe distance to avoid injury.
Eliminate the hazard before digging.

Firefighters are responsible for their safety and the safety of their team, and may also need to tend to casualties in need of assistance.
Fire safety equipment includes:
- Pressure gauge
- Carrying handle
- Discharge lever with pin/tamper seal
- Hose
- Extinguishing agents (water, AFFF, dry powder, dry chemical, etc.)

Water:
- Non-toxic, plentiful, and efficient
- Converts from liquid to steam, absorbing heat in the process
- Good range and penetration
- Absorbs more heat per volume than any other agent
AFFF:
- Does not leave a residue
- Non-freezing
- Limited range
- Affected by wind
Dry Powder:
- Can be hazardous if used in a confined or unventilated space
- Cold shock to electrical equipment
Dry Chemical:
- Limited cooling effect
- Leaves a residue
- Can be corrosive
Multi-Purpose Dry Chemical:
- Leaves a residue
- Limited range
- Limited cooling effect
Class A Foam:
- Leaves a residue
- Will freeze
- Requires selection of correct foam for the fire application
