Ventilated area
Ensure that the area is in the open or that it is adequately ventilated before breaking into the system or
conducting any hot work. A degree of ventilation shall continue during the period that the work is carried out. The
ventilation should safely disperse any released refrigerant and preferably expel it externally into the atmosphere.

Repairs to sealed components
During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being
worked upon prior to any removal of sealed covers, etc. If it is absolutely necessary to have an electrical supply to
equipment during servicing, then a permanently operating form of leak detection shall be located at the most critical
point to warn of a potentially hazardous situation. Replacement parts shall be in accordance with the manufacturer
