Fire Protection
Maintenance
Any shutdown due to maintenance should be notified to fire authority in advance. This is especially applicable if the automatic sprinklers are under maintenance. Such shutdown should be scheduled during normal working hours and finished in shortest possible time. If required, special precautions such as fire petrol, temporary water connection etc should be employed.
