To protect against electrocution, the correct procedures to follow are:
a. Isolation - This involves ensuring that electrical equipment is turned off and disconnected from power sources before working on it.
c. Lockout/Tagout - This is a safety procedure used to ensure that dangerous machines are properly shut off and not able to be started up again until the maintenance work is finished.
While handwashing and safe driving are important safety practices in their own right, they are not specific to preventing electrocution.
So, the best answers are a. Isolation and c. Lockout/Tagout.
