3.6.5 Fire Extinguishing System (CE)

● Semi-annual maintenance of the fire extinguishing system involves system
commissioning. Before the maintenance, inform the related administrative
departments that the fire extinguishing system will be maintained and stop
working.
● Before maintaining the fire extinguishing system, remove the electrical actuator
from the container valve of the fire cylinder. This prevents the extinguishant
release due to misoperations, and prevents accidental damage.
● After the maintenance, reconnect the electrical actuator, and inform the
administrative departments that the fire extinguishing system has become
operational.
