Preparation and running carbon dioxide extinguishing system

• The temperature in the carbon dioxide quench at the station must not exceed 40 ° C.
• All system valves and other devices must be marked to indicate the room for which they are intended: the station premises must have a system diagram with the specified triggers, brief instructions for starting and servicing the system.
• The collectors of the carbon dioxide quenching station must be equipped with manometers with an upper measurement limit exceeding the pressure of the hydraulic carbon dioxide cylinders by at least 980 kPa; the scale interval of the manometer must not exceed 490 kPa.
• Carbon dioxide cylinders must be placed vertically upside down at the station and securely fastened. It must be possible to inspect the cylinders and check the carbon dioxide content. There must be a gasket under each cylinder. Cylinders must be numbered.
• When the cylinders are filled and replaced, the cylinder valves or valve opening actuators are sealed.
• The supply and exhaust ventilation of the station must be in order and ready for operation.
  

In order to keep the carbon dioxide extinguishing system permanently in place, it is necessary to:

• Check the cleanliness of the tubes and syringes once a month by purging them with compressed air;
• check the clearance of the start and transfer valves;
• check the carbon dioxide content of the cylinders once a year, the condition of the rubber parts of the cylinder valves and auxiliaries, the condition of the starting system, pneumatic switches, safety valve.
• When storing compressed carbon dioxide in cylinders, devices must be provided for weighing the cylinders or measuring the gas level in the cylinders.
• The station premises must always be locked. Keep the keys in a box attached to the station room and sealed.
