Water chiller lockout procedure

A water chiller holds electrical, water and chemical energy. Here is where it hurts people, and the procedure for yours: the placard for the machine and the written procedure for the binder.

E1W1C13 energy sources on a typical water chiller

Where a water chiller hurts people

  • Refrigerant stays under pressure with the power off; only a certified technician opens the circuit.
  • Drives hold a charge; wait the time on the label.

Write the procedure for your water chiller

List every source of energy that can move, power or hurt. The placard builds as you go, and the checks run on every change.
