Storing R290

Regulations

Regulations for storing R290 need to be followed from:

Approval needed by Health and Safety Executive (HSE), Environment Agency (EA) and Fire Authority

PPE

• While the workers are handling R290 refrigerant you need to use a portable gas detector. (including when transport and storage)

• Detector can be clipped to clothing or placed on the floor within the working area.

• It should be switched on for the duration of the work and set to alarm at 25% of the LFL, to alert staff members of imminent flammable concentration.

• Technicians can be alerted whenever an inadvertent release of flammable refrigerant occurs.

• Technicians are then capable of immediately acting on the relevant emergency procedures

VOLUME OF THE UNIT

When storing machines containing R290, you need to know the internal volume of the refrigerant circuit.

This is important because knowing the internal volume of refrigerant determines how the flammable machines are stored.
