To protect against electrocution, the most relevant procedure among the options you provided is:
c. Lockout/Tagout
Lockout/Tagout (LOTO) is a safety procedure that ensures that machinery or equipment is properly shut off and not able to be started up again until maintenance or servicing is completed. This helps prevent accidental energization that could lead to electrocution.
While isolation (which generally refers to isolating electrical power) is a valuable procedure, it's often included within lockout/tagout practices. Handwashing, on the other hand, is not directly related to electrical safety or protection against electrocution.
In addition to LOTO, here are some other important practices for protecting against electrocution:
- Use of Personal Protective Equipment (PPE): Wear appropriate gear, such as rubber gloves and insulated tools.
- Maintain safe distances: Keep a safe distance from energized equipment.
- Regular inspections: Check equipment and tools for any signs of wear or damage.
- Training: Educate all personnel on electrical safety practices.
Remember, safety first!
