A worker was using a hand-held 5-inch angle grinder while
working on a wrought iron gate when the abrasive wheel broke
and pieces flew off. One piece cut into the worker's thigh,
severing a large artery. The worker collapsed from the blood
loss and later died.
The accident investigation found that the abrasive wheel that broke was
rated for a maximum of 6,110 rpm but the angle grinder was rated at 10,000 rpm.
As well, the abrasive wheel was larger than 5 inches in diameter, preventing the
installation of the guard provided with the grinder.
Safe work practices:
- Use only abrasive wheels that match the diameter and speed (rpm) rating
of the grinder.
- Before using a grinder, always make sure the guard is installed.
- Ensure that workers are adequately trained in the safe use of grinders and
that they know about rpm limitations.
- Always wear adequate eye and face protection when using a grinder. Hearing protection
and flame-resistant clothing must also be worn.
