Risk Assessment: Works. Electricity Lines
RISK
30/40/50 Objects falling due to collapsing or landslide
when being handled or due to coming loose.
RISK FACTORS
- When carrying out work on higher levels.
- When using mechanical means for elevating loads (cranes, truck-mounted cranes, the client’s overhead cranes, etc.) and auxiliary equipment (slings, straps, etc.).
- Equipment and packaging (due to poor procedures).
- Failure of cables or securing elements slipping (conductor self-gripping clamps, sleeves, tensors, etc.).
- Falling objects that have come loose or landslides during work inside trenches or pits.
PREVENTIVE MEASURES
Rules for acting
- Hand tools tied or in a tool bag.
- Signpost the work area.
- Respect safety distances.
- Plan in advance operations in which mechanical means for elevating loads and auxiliary equipment is going to be used. Manoeuvres are to be directed by one single person.
- Check CE auxiliary equipment previously (slings, straps, ropes, chains, etc.) .
- Guiding loads manually is forbidden, as is the transit of personnel below suspended loads.
- Always follow the manufacturer’s instructions.
- Materials or tools are never to be thrown up or down. They are to be raised using a rope or other auxiliary means (jib, poles) with the load properly secured
- Employ double retention and securing of conductors (double conductor self-gripping clamp).
- Clamps are to be the appropriate ones so that the conductor does not fall.
- Use tensing tables to regulate conductors.
- Trench and pit works:
- Unless the inclination of the cut coincides with the natural slope of the ground, it will be necessary to adopt protection measures (shoring, continued examination of the conditions of the ground, etc.)
- Do not enter into trenches with a depth > 1.30 metres without shoring.
- Equipment and materials are generally to be stockpiled at a reasonable distance from the top of slopes depending on the depth of the trench or pit.
- Trenches are to be provided with metal ladders that stick out 1 m above the upper level of the cut, unless there are safe access ramps (with a suitable slope).
- Pit mouths with a dangerous slope are to be protected with solid handrails with an intermediate rail and skirting that impede materials and personnel from falling into the pit.
- One or more workers are to remain outside the trench, pit or gallery to help in the case of an emergency and evacuation.
- In deep pits and trenches, workers are to use harness-type safety belts joined to a fall and rescue device
