Dam and Reservoir Safety Awareness
Construction work on dams and reservoirs involves working near or within large bodies of stored water. The consequences of a dam failure during construction are catastrophic, with the potential for loss of life downstream. Workers face drowning risks, unstable ground conditions, and the challenge of working in remote locations with limited emergency access. The Reservoirs Act places specific legal duties on reservoir construction and any work must be supervised by a qualified civil engineer.
- Wear personal flotation devices at all times when working within two metres of reservoir water.
- Ensure a qualified civil engineer supervises all work affecting the structural integrity of the dam.
- Install edge protection and barriers around all open water within the construction area.
- Provide rescue equipment including throw lines and lifebuoys at accessible points around the reservoir.
- Monitor water levels, rainfall, and inflow conditions continuously throughout the construction period.
- Establish emergency procedures covering dam breach, flooding, and site evacuation scenarios.
- Maintain safe access routes that allow emergency vehicles to reach the site at all times.
- Brief all workers on the specific hazards of the reservoir environment during site induction.
- Ensure communication systems are reliable in the remote location including mobile phone coverage or radios.
If water levels rise unexpectedly or dam movement is detected, evacuate the site immediately via the designated escape routes. Sound the downstream warning system if installed. Call 999 and the reservoir panel engineer.
- Dam construction failures can cause catastrophic flooding with the potential for mass casualties.
- A qualified civil engineer must supervise all work affecting the structural integrity of the dam.
- Personal flotation devices are mandatory for everyone working near reservoir water.
- Remote locations mean longer emergency response times, making on-site preparedness essential.
- Monitor water levels and weather continuously because conditions can change rapidly.
- The Reservoirs Act imposes strict legal duties on anyone carrying out work on large raised reservoirs.
