1. Which source of accidents is the principle cause

Falls

Using hand tools

Handling heavy equipment

Striking against material or equipment

Falls are the principal cause of accidents because they can result in serious injuries or even fatalities. When workers fall from heights, such as ladders or scaffolds, they are at risk of broken bones, head injuries, or spinal cord damage. Falls can also occur on the same level due to slippery surfaces or tripping hazards. These accidents can be prevented by implementing proper safety measures like providing fall protection equipment, maintaining clear walkways, and conducting regular inspections to identify and mitigate potential fall hazards.
