Safety rules for the use of R290 refrigerant


First, in the storage process stored in a cool, ventilated warehouse. Away from fire, heat. The temperature is not more than 30 ℃. Should be stored separately with the oxidant, halogen, avoid mixed storage. Explosion-proof lighting, ventilation. Prohibit the use of mechanical equipment and tools that are prone to sparks. Storage area should be equipped with venting emergency treatment equipment. 


Second, the process of transport in the shaft 

1, only the day of the amount of R290 refrigerant is allowed to load a licensed pressure vessel, allowing the vehicle to be transported. 

2, in the transport process, installed R290 refrigerant containers must be tight in the vehicle. 

3, in the transport of R290 refrigerant vehicles must be equipped with gas alarm device. 

4, in the transport of R290 refrigerant vehicles do not prohibit smoking. 


Third, in the production process

 l, all staff will not prohibit smoking. 

2, operating personnel are not allowed to wear clothes that produce static electricity. 

3, to avoid working in a limited space, should be in large space in the production of production. 

4, prohibit all use the work of open flame. All piping connections should be connected using a locking ring. 

5, not allowed to use vacuum cleaners, hair dryer and other electric appliances.

6, when discharged from the refrigeration system R290 refrigerant, the hose should be used to enter the outdoor atmosphere.

7, all substation must be suitable for flammable and explosive gases. 


Fourth, [filling R290 refrigerant safety issues] 

l, in order to avoid combustible gas accumulation, the need to install a strong ventilation device. 

2, in addition to ventilation and safety systems, the need to configure the standard explosion-proof electrical equipment. 

3, with the gas sensor components to continuously monitor the possible leakage area: when the concentration exceeds the minimum explosion limit of 15% -20%, that is, alarm and double ventilation; when the minimum explosion limit of 30% -35%, cut off Monitor the area of all non-explosion-proof electrical connection, leaving only full-speed rotation of the explosion-proof fan. 

4, in the equipment charge R290 refrigerant before the equipment must be revealed to pick up.
