• Use a self-retracting safety knife as your standard cutting tool on site.
• Cut away from your body and keep your free hand behind the cutting line.
• Replace blunt blades promptly — a sharp blade requires less force and pressure.
• Wear cut-resistant gloves rated EN 388 Level 5 when using bladed tools.
• Store knives in a holster or pouch when not in use — never in your pocket.
• Dispose of used blades in a designated sharps container, not in general waste.
• Select the correct knife type for the material — use hook blades for sheet goods.
• Place the material on a stable surface before cutting — never cut freehand.
• Retract or sheath the blade immediately after completing each cut.
• Attend first aid immediately for any blade cut — even minor cuts can need stitches.

• DON'T use a fixed-blade knife if a retractable or safety knife can do the job.
• DON'T cut towards your body, legs, or any part of yourself at any time.
• DON'T carry an open blade while walking or climbing between work areas.
• DON'T use a knife blade as a screwdriver, pry bar, or lever on site.
• DON'T snap blades off knives without using the built-in snapping mechanism safely.
• DON'T put used blades loose in your pocket, toolbox, or general waste bins.
• DON'T lend your knife to someone without checking they know how to use it.
• DON'T continue cutting with a blunt blade — change it before applying more force.
• DON'T use excessive downward pressure — let the blade do the cutting work.
• DON'T ignore a minor cut — clean it, apply a dressing, and report it.
