Safe Working Extreme Weather Flashcards
give example of extreme weather events
Low Temperature
High Temperature
Fog
Storm and Wind
What kind of damage/disruption can extreme weather events cause?
- Obstruction on the tracks
- Water on the rail
- Obstruction in the overhead and fouling tracks
- Broken rail
- Buckled rail
What issues can cold weather cause?
- Broken rails
- Low adhesion when braking and powering
- Excessive arcing from the pantograph
What could happen with broken rails?
- Lead to signal failures
- Major defects with track structure
- Derailment in extreme cases
If you encounter a suspected buckled rail, what should you do?
Slow the train down or attempt to stop the train prior to the location.
Report to Train Controller at Metrol immediately.
What issues can hot weather cause?
- Buckled rails
- Damaged or sagging overhead wires
- Trackside fires
What could cause a trackside fire?
- Vegetation igniting, sticking brakes causing excessing heat and potentially igniting trackside vegetation.
- Thrown rubbish like glass bottles can generate heat and ignite dry grass
If you’re unsure of the proximity of a fire, should you proceed?
NO
What kind of damage can storm and wind do?
Bring down trees Create flash flooding Lose overhead power Entangled debris in overhead wires Reduce visibility Affect signalling systems
What do you do if you see debris entangled in the overhead?
Stop prior using emergency if necessary.
If you can’t stop before the debris, lower all pantographs to avoid getting them entangled.
Who inspects the Broken Rails?
Track maintenance personnel
When can a driver be permitted over affected portion of track with water over the rail head?
Track Maintenance has inspected and certified the track fit for traffic;
Proceed at a maximum speed of 5km/h
The water level is not more than 75mm above the rail;
The water is not moving
Who inspects the rail when there’s floodwater over the rail or water below the rail?
Track Maintenance Representative
If the water is subsiding or below the rail head, what is the drivers duties?
If the water is NOT FLOWING:
- Proceed at max 15km/h
- Track Maintenance Representative must inspect the track before normal speed is resumed.
- If you’re the first person to go over the section of track with water subsiding, Train Control will advise and you need to report back after completing the section on the state of the track
Who do you advise if you see water over the rail head?
Train Control immediately
