‘Cave in’or a collapse, is the main hazard of an excavational site. The employees and other people at the excavation site are at risk of being buried and injured from excavational collapses, while working in the the excavated area. They are susceptible to fall into one too. Labors also get injured from being hit by the fall of the heavy machineries at the site and their malfunctioning.
The hazards can be categorized in four broad categories;
We shall now mention the hazards and the control measures for them:

Injuries due to fall from height: harness, scaffolding, safety lines, edge protection and other safety gears, can prevents fall from great heights.

Hand tools: Periodic inspection, maintenance.Repairs and replacement when required should not be overlooked.
Machines: The machines need to be inspected regularly. Supervision and training is required for efficient operation and avoiding any accidents.
Moving vehicles: A good control of vehicular movement, proper road layout, signs, vehicle maintenance, is essential.
