Industry applications

Flammable liquids

Containers should be stored in the open air where practical, but if stored inside, five air changes per hour is considered a sufficient ventilation rate.

• Standard 205 litre metal drums should be stacked no more than three high and preferably on pallets or racking.
• The maximum stack size should be 300,000 litres with at least 4 metres between stacks.
• Storage should be on an impervious surface such as concrete and be bunded with drainage towards a sump or other suitable handling system.

LPG cylinders

Cylinders should be stored preferably in the open air on a concrete or load-bearing surface.

• Flammable liquids, combustible, corrosive, oxidising materials, toxic materials or compressed gas cylinders should, in general, be kept separate from LPG containers.
• Containers should be stored with their valves uppermost.
• The maximum size of any stack should not exceed 30,000kg.
• For storage indoors, no more than 5000kg may be stored in each purpose designed building compartment and a maximum of five compartments may exist in a single building.

Chlorine cylinders

• The vast majority of chlorine cylinder and drum stores are located indoors and should be solely used for storing chlorine.
• Access doors should fit closely to help contain any leak.
• These stores should be protected from any nearby radiant heat hazards.
• The store should be at least 5 m from any roadway.
• A cylinder store should be at least 20m from the site boundary and a drum store 60m.
• Chlorine gas detectors / alarms should normally be provided.
• Risk assessments should be carried out to consider hazards arising from mishandling (dropping of containers in transport/handling), incorrect operation of valves and failure to connect correctly, maintenance errors and damage by external sources (domino, vehicle impacts, etc.)
