Glossary · Hazards and harm
Cutting hazard
In machine safety, a cutting hazard is a mechanical hazard created by a sharp edge, a blade or a cutting process that can cut or sever tissue.
- Machine safety
- Risk assessment
- Maintenance
In one sentence
A cutting hazard comes from blades, knives and sharp edges on tools, machine parts or workpieces, in operation and during blade changes.
Example
A band saw has a moving blade at the point of operation; an adjustable guard covers the blade except for the section needed for cutting, and the manual describes blade changes with the machine isolated.
How it applies
- Machine safety: Cutting hazards come from tools in motion (saws, knives, slitters), from stationary sharp edges (sheet-metal burrs, blade holders) and from the workpiece itself. Guard the point of operation where possible and remove sharp edges by design.
- Maintenance: Blade changes and cleaning expose people to blades that are stationary but still sharp. The maintenance manual should specify tools, blade covers and cut-resistant gloves.
- Technical documentation: Distinguish hazards during operation from hazards during setting and cleaning. They need different measures and warnings.
- Evidence: Record which edges remain accessible and why, so the residual risk is traceable.
Cutting hazard vs. shearing hazard
A cutting hazard needs only one sharp element. A shearing hazard arises between two parts passing each other.
