Transport rules for gases and dry ice
On the road
The campaign is being led by the European Industrial Gases Association (EIGA). It says that every year incidents occur when under-prepared businesses and individuals transport gas cylinders, cryogenic receptacles and dry ice (solid carbon dioxide). The problems it cites include:
- insufficient ventilation of the vehicle
- cylinders not properly secured
- valves of cylinders unprotected or not closed properly before departure
- regulators or other equipment left connected during transit; and
- cylinders and dry ice packages left in the vehicle for extended periods after arrival at the destination.
Note. The release of gas into an enclosed vehicle is likely to alter the composition of the air and make it unbreathable. In some cases there may also be a fire or explosion hazard.
Transport of dry ice
Dry ice is used in a number of industries including healthcare, scientific research, food and the performing arts. When exposed to ambient temperature it releases carbon dioxide; this causes a problem in an enclosed space because the atmosphere can become hazardous.
Tip 1. Dry ice should only be transported in specially designed thermal storage containers which must be kept closed, upright and secure. Gas-tight containers should not be used. The EIGA has issued a leaflet Safe transport of dry ice to assist you (see The next step ).
Tip 2. The driver’s cab should be separate from where the dry ice is located, i.e. it shouldn’t be carried in a car.
Tip 3. On arrival at the final destination the transport compartment of the vehicle must be opened up and allowed to ventilate before entry. The dry ice should then be unloaded swiftly and moved to a suitable storage location.
Transport of gases
The transport of compressed gases is regulated by the Carriage of Dangerous Goods and Use of Transportable Pressure Equipment Regulations 2009 , and whilst the EIGA leaflet provides helpful advice, firstly look to the HSE.
Tip 1. The HSE has provided simple guidance for those carrying one or two gas cylinders which suggests that you: (1) use a well-ventilated vehicle; (2) secure the cylinder so it can’t be thrown about; and (3) make sure the valve is fully closed (see The next step ).
Tip 2. Common sense measures to apply, as outlined by the EIGA, include ensuring good ventilation, having a safety data sheet for the substance in the vehicle and unloading promptly on arrival.
Tip 3. Provide instructions to drivers regarding the precautions required and what do in the event of a leak.
