Under Cal/OSHA, what is the purpose of a lockout/tagout (LOTO) procedure?
a.To label refrigerant cylinders
b.To isolate and secure energy sources so equipment cannot start during service
c.To measure superheat
d.To size ductwork
Explanation
Lockout/tagout requires de-energizing and physically locking energy-isolating devices, then tagging them, so machinery cannot be energized while a technician services it. This protects workers from electrical shock and unexpected startup. Cal/OSHA Title 8 sets the specific requirements.
