g) 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.

operating adequately and are not obstructed; if an indirect refrigerating circuit
is being used, the secondary circuit shall be checked for the presence of
refrigerant; marking to the equipment continues to be visible and legible.
markings and signs that are illegible shall be corrected; refrigeration pipe or
components are installed in a position where they are unlikely to be exposed to
any substance which may corrode refrigerant containing components, unless
the components are constructed of materials which are inherently resistant to
being corroded or are suitably protected against being so corroded.
