Puncture hazard
Also known as: stabbing hazard
In machine safety, a puncture hazard is a mechanical hazard from pointed tools, projections or materials that can penetrate the body.
- Machine safety
- Risk assessment
In one sentence
A puncture hazard comes from needles, nails, drill bits, wire ends and sharp projections that can pierce the body.
Example
A nailing station on a pallet assembly line can drive a nail through a hand; a two-hand control device keeps both hands away from the nailing head during the stroke.
How it applies
- Machine safety: Sources include needles, nailing and stapling heads, drill bits, wire ends, gripper spikes and sharp projections on workpieces. Guards, two-hand control devices and removing projections by design are typical measures.
- Injection: High-pressure fluid from a hydraulic leak can penetrate the skin with barely a visible wound. ISO 12100 lists injection as a separate consequence; cover it wherever hydraulics are present and describe it in the maintenance manual.
- Technical documentation: Describe the response where it is not obvious, for example that a hydraulic injection injury needs immediate medical attention even if it looks minor.
- Evidence: Record which pointed elements remain accessible and why.
Puncture hazard vs. cutting hazard
A cutting hazard involves an edge moving along or across tissue. A puncture involves a point penetrating it.
