Machine Safety
Use lockout/tagout procedures to de-energize conveyors and other machinery before attempting to free any jams.
Secure chutes and hatches to reduce injuries from swinging parts.
Make sure guards are in place to protect you from moving parts of machinery and tools before you operate the equipment.
Overhead Hazards
Be sure that form work, casting and stressing operations are adequately braced and chocked to avoid sudden release of materials.
Make certain that rigging is in place to protect against falling objects and materials during hoisting and stacking procedures.
Do not walk or work under overhead loads.
