 ATEX and DSEAR: Liquified petroleum gas (LPG) issues

Q1     Are bulk LPG storage, LPG cylinder filling and outdoor cylinder storage areas exempt from DSEAR? 

A1      No. DSEAR applies to all the situations described; the Regulations apply wherever a dangerous substance is, or is liable to be, present in a workplace.

Q2     I have an outdoor LPG cylinder storage area. Do I need to zone it?

A2      Damage to cylinders can occur during mechanical handling operations. The issue has been discussed with the LP Gas Association, and they have published a Code of Practice 7 - The Storage of Full and Empty LPG Cylinders and Cartridges. Provided that the outdoor storage area is designed, constructed and maintained fully in accordance with the Code of Practice, HSE has accepted that it is not essential to designate the LPG outdoor storage area as zone 2, and so ATEX compliant vehicles are not needed. Where these conditions cannot be complied a zone 2 area may exist.

Q3     I have an indoor LPG cylinder storage area. Do I need to zone it?

A3      Damage to cylinders can occur during mechanical handling operations. The issue has been discussed with the LP Gas Association, and they have published a Code of Practice 7 - The Storage of Full and Empty LPG Cylinders and Cartridges.  This guidance requires a site specific risk assessment to be carried out for internal storage of cylinders as the zone would depend on a number of factors including ventilation provision. Where an area has been zoned then suitable ATEX equipment would be required.
