Plant Shutdown Procedure and Action in the Event of a Refrigerant Leak

In the Event of a Malfunction or Emergency 

Emergency devices installed will stop the plant via the control system in the event of amalfunction or high level ammonia leak in the plantroom.

Should any item of plant sound abnormally noisy or be vibrating, press a local "emergency stoplock".

IF IN ANY DOUBT BEFORE RESTARTING THE PLANT, CONTACT THE SERVICEPROVIDER. 

In the Event of a Carbon Dioxide Leak 

In the event of an emergency such as a CO2 leak, the main priority is to EVACUATE THE AREAURGENTLY and prevent others from entering until an experienced Refrigeration Engineerarrives.

DO NOT ATTEMPT TO ISOLATE THE LEAK YOURSELF. Refer to COSHH informat ioncontained within this manual. 

CO2 in the liquid or solid state can cause cold burns to exposed skin. In the gaseous state, CO2is heavier than air so a leakage can result in the production of ‘pools’ of inert atmosphere in low,

unventilated areas. Although there is a small percentage of CO2 in the air we breath, and it isessential in regulating breathing, prolonged exposure to higher concentrations of the gas canlead to headaches, exhaustion, asphyxiation, paralysis, loss of consciousness and ultimatelydeath.
