When you see unsafe work practices, correct the situation immediately and discuss the unsafe act with the worker. Additional training and follow-up can ensure that employees follow safe procedures.
Correct unsafe conditions as soon as you discover them. If that's not possible, lock away highly hazardous equipment and tag it so others will know it poses a threat. Document less serious conditions and follow up with the maintenance department to confirm it takes corrective action.

Use Checklists
Checklists serve as reminders of what to inspect. They also direct the inspections and allow for immediate recording of all findings and recommendations.
In larger organizations, it's often wise to develop a separate checklist for each department. Each plant, department or crew can create its own list specific to its area. Simply checking off items on the list will not suffice. Use the checklist as an inspection tool. Record any and all hazards you see during the inspection, even if they don't appear on your checklist.
