Where severe injuries happen.
WHAT THE HAZARDS ARE
Entanglement in moving parts Crushing and trapping Cutting Ejected material Stored energy released unexpectedly
WHY MACHINERY DOMINATES SERIOUS INJURY
Moving parts cause amputations in an instant and irreversibly.
WHAT GUARDS DO
Prevent contact with dangerous parts.
WHAT TO REQUIRE
That guards are fitted, in place and functional.
WHAT TO NEVER ACCEPT
Guards removed for speed Interlocks defeated Reaching into machines while running
WHY THOSE HAPPEN
They make work faster, and nobody is hurt the first hundred times.
WHAT TO ESTABLISH
That defeating a guard is treated as a serious matter.
WHAT ISOLATION MEANS
Disconnecting energy and securing it so it cannot be restored while someone is working.
WHAT ENERGY INCLUDES
Electrical Mechanical, including stored motion Hydraulic and pneumatic pressure
Gravity: raised parts that can fall
WHY STORED ENERGY MATTERS
Machines that are switched off can still move.
WHAT THE PROCEDURE SHOULD REQUIRE
Shut down Isolate every energy source Secure the isolation Verify it is dead Release stored energy
WHY VERIFY
Assumed isolation kills people.
WHAT TO ESTABLISH
That only the person working may remove the isolation.
WHAT MAINTENANCE REQUIRES
Machines maintained so they are safe Guards repaired rather than removed Records
WHAT TRAINING REQUIRES
Nobody operates equipment they have not been trained and assessed on.
WHAT TO RECORD
Training, by person and machine.
