Transport Matters

Driving can be hazardous at the best of times, but the safe carriage of dangerous goods requires compliance with complex regulations, an absolute commitment to best practice and professional levels of driver training and skill.

BCGA member companies actively promote safety during any transport journey to ensure their goods are delivered safely, the safety of vehicle crews and the safety of the general public. Within BCGA, transport matters are the responsibility of Technical Sub-Committee (TSC) 4. Members can access information on TSC4 via the ‘Members‘ area.

Any goods that pose a risk to people, property and the environment are classified as dangerous goods. For transport, these goods need to be packaged correctly to ensure that they are safe for carriage. Gases are classified as dangerous goods. The transport of dangerous goods is regulated in order to prevent, as far as possible, accidents involving people or property, damage to the environment, to the means of transport employed or to other goods being transported. Each mode of transport, (air, sea, road, rail and inland waterway) has its own regulations but they are now largely harmonized with the United Nations Economic Commission for Europe (UNECE). Recommendations on the transport of dangerous goods – Model Regulations.

The UN Model Regulations use a classification system in which each dangerous substance or article is assigned to a CLASS, depending on the nature of the danger it presents. Gases are assigned to Class 2, and are further sub-divided into three divisions:

Division 2.1
Flammable gas
Division 2.2
Non-flammable non toxic gas
Division 2.3
Toxic gas

Transport

Air

Dangerous goods which are transported by air have to follow the International Civil Aviation Organization (ICAO) Regulations. The International Air Transport Association (IATA) publish their IATA Dangerous Goods Regulations which includes national and individual airline requirements. The Civil Aviation Authority (CAA) is the UK’s aviation regulator.

Sea

Dangerous Goods which are transported by sea have to follow the International Maritime Organization (IMORegulations, which are implemented via the International Maritime Dangerous Goods (IMDG) Code. The Maritime and Coastguard Agency (MCA) regulates transport by sea.

Road & Rail

Dangerous goods which are transported by road or rail within Great Britain have to comply with the requirements of The Carriage of Dangerous Goods and Use of Transportable Pressure Equipment Regulations, as amended. These Regulations implement the Agreement concerning the International Carriage of Dangerous Goods by Road (ADR) and the Regulation concerning the International carriage of Dangerous Goods By Rail (RID). The Secretary of State for Transport, within the Department for Transport (DfT), is the competent authority for Great Britain.

Everyone transporting gas cylinders in the course of their work is required to comply with ADR and has to meet certain basic minimum legal safety requirements. A threshold level is set based on a quantity of transport units,  if below the threshold  you are exempt from some requirements of ADR but if you exceed the threshold level you are required to comply with the full ADR regulations. Refer to BCGA GN 27, Guidance for the carriage of gas cylinders on vehicles.

It is recommended that gas cylinders are transported in open vehicles, open containers or trailers. If it is necessary to transport gas cylinders inside a vehicle then good ventilation is required. In all spaces, the use of roof ventilators along with side vents will increase the quantity of ventilated air in the vehicle. Once the journey is completed gas cylinders should be removed from the vehicle. If there is any possibility of gas accumulating within a vehicle space then appropriate warning signs are to be displayed. Common hazards come from the use of dry ice, i.e. asphyxiant gas, and also the careless handling and use of welding gas cylinders and equipment leading to a build-up of flammable and oxidant gases. Refer to BCGA CP 31 and BCGA GN 27.

An empty, or partially filled, gas container that has contained a dangerous substance is to be treated the same as a full container and is therefore subject to all the relevant transport dangerous goods regulations. Only if adequate measures have been taken to nullify any hazard may the container be treated as non-hazardous.

Requirements

When dangerous goods are being transported, the driver of the vehicle is required to carry certain documents, these include:

All personnel involved in the carriage of dangerous goods require training and instruction, this includes administration staff, site security staff as well as drivers and vehicle attendants. Additionally, certain drivers of road vehicles carrying dangerous goods may need to hold a vocational training certificate (VTC, or “ADR certificate”). In the UK the VTC is obtained after a driver has attended a training course and successfully completed an examination, approved by the DfT. The examination has to be appropriate to the class or classes of goods which are to be carried on the vehicle. Refer to the DfT Website and  Refer to BCGA GN 35.

Dangerous goods can be attractive to thieves and terrorists.  Everybody involved in the storage and distribution of dangerous goods should take appropriate security measures and precautions to minimise their theft or misuse.  ADR, Chapter 1.10, has specific requirements.  BCGA CP 40 provides guidance. DfT provide guidance on security requirements for moving dangerous goods by road and rail, including a training film on the security of high consequence dangerous goods, titled ‘Lockdown’. The film is available on request from DfT or it can be downloaded from the original makers.

DGSA. Businesses that handle (including the transport related activities of loading and unloading), process or transport dangerous goods need to appoint a dangerous goods safety adviser(s) (DGSA). DGSAs need to have obtained a vocational training certificate (VTC) after undergoing training and successfully completing a written examination approved by the DfT. DGSA VTCs are valid for 5 years. Refer to BCGA GN 35

The role and duties of a DGSA are laid out in ADR, Chapter 1.8. As part of these duties the DGSA is required to produce an Annual Report. EIGA provide a template for an annual report for Class 2 dangerous goods (gases), refer to EIGA 156.   Further  information on the roles and activities of DGSA’s is available through the British Association of Dangerous Goods Professionals (BADGP).

Additional requirements and standards regarding transportation.

There are specific requirements for vehicles driving through tunnels, further information is available from:

Vehicles used for freight transportation have to meet certain standards. Useful information can be found at:

There is also increasing use of various gases providing the fuel for vehicles. Gas powered vehicles have many advantages including low, or zero, emissions from exhausts and a reduced carbon footprint. More information is available on our Alternative Fuels for Vehicles webpage.
