What are electrical hazards, mechanical hazards, gravity, residual motion, in-going nip points, shear points, crush points, the release of hazardous materials, and temperature extremes?
This is what you must do after you've deenergized the machine/equipment, applied your lock and tag, and released any potential/stored energy.
What is verify that the equipment is in a safe state?
This is what must be completed and signed by a lead, supervisor, or designee before hot work can be done outside a designated area and the work cannot be done 35'+ from all combustibles.
