Transport of hazardous
goods - regulations and requirements
The transport of hazardous goods must be carried out with specialised vehicles and must comply with a number of regulations.
Hazardous goods are governed by a specific set of regulations because there is a risk associated with them. It is possible to transport hazardous goods, but only by companies that specialise in these activities and have the necessary certifications. Failure to do so entails the possibility of heavy penalties, in addition to the risk involved.
Only a company that offers domestic and international transport specialising in hazardous goods can carry out this activity with guarantees.
What is the transport of hazardous goods?
The transport of hazardous goods encompasses those carriage activities that can only be carried out under specific authorisation and in compliance with international regulations.
The main definition is provided by the United Nations (UN) in its Transport of Hazardous Goods Regulations 1996, updated in 2023. This organisation indicates which are the main hazardous goods, classifying them by type. Hazardous goods are goods which, by their nature, may cause risk to persons or property.
Obviously, in order to carry out this transport safely, it is mandatory to use a specialised company that offers a range of suitable transport solutions and guarantees compliance with each of the regulations.
Classification of hazardous goods
The classification of hazardous goods consists of 9 classes, which are further subdivided into subcategories. Each of these is listed below:
Explosive goods
Explosive goods are solid or liquid materials which, when mixed, can cause explosions, noise or harm to the environment. This includes explosive substances, pyrotechnics and explosive items.
Gases
Gases may be pure or a mixture; flammable or non-flammable; toxic or non-toxic. Examples are butane gas, nitrogen, propane, acetylene or oxygen. To be considered hazardous, they must be at 20°C in a gaseous state or, at over 50°C, at a pressure of 3 bar.
Flammable liquids
Flammable liquids can cause explosions due to heat or flame effects. These are chemicals, such as paint, fuels, solvents or alcohol.
Flammable solids
Flammable solids are materials or articles which, above a certain temperature or on contact with a flame or abrasion, can burn. Examples are cellulose, rubber, sulphur, phosphorus or coal.
Oxidising substances
Oxidising substances are of two types: oxidisers or organic peroxides. In the first case, this includes nitrates, sodium chlorate and lead dioxide. Organic peroxides are thermally unstable, which, in some cases, leads to problems and potential explosions.
Toxic and infectious substances
Toxic and infectious substances are of various types. A toxic substance such as a pesticide or cyanide, through contact, inhalation or ingestion, can harm human health. Infectious substances, which are common in the health sector (clinical waste), can cause diseases in humans or animals.
Radioactive materials
Radioactive materials, whether linked to the nuclear industry or to certain clinical waste, can cause harm to humans by releasing particles or radiation. Materials frequently transported include plutonium, uranium or medical radioisotopes.
Corrosives
Corrosive substances are those which, on contact, produce chemical reactions that cause damage to people (skin) or to goods or objects in contact with them. Examples of corrosive substances are certain acids, such as hydrochloric acid or sulphuric acid, which can cause severe burns and damage materials such as metals, plastics and fabrics
Other substances and articles
Class 9 covers other hazardous substances and materials which are not included in other categories. The best-known example is asbestos, but there are also lithium batteries and self-flammable liquids.
Rules and regulations on the transport
of hazardous goods
National regulations on the transport of hazardous goods are regulated by Royal Decree 97/2014, of 14 February, regulating the transport of hazardous goods, which transposes international regulations (ADR and UN Regulation).
The ADR agreement on the transport of hazardous goods is the main EU-wide regulation for land transport. Signed in 1957, it is updated periodically (most recently in 2023). Today, it is applied in more than 50 European, Asian and African countries. The ADR follows the recommendations of the UN Hazardous Goods Regulations.
The current legislation specifies which type of vehicles carry each class of hazardous goods, the packaging, containers, the numerical identification of each class (UN number), the pictographic symbols and the training required for drivers. The transport of hazardous goods without ADR is unfeasible, because the authorities will be able to stop vehicles that do not comply with the rules and above all because of the risk to which the load, the vehicle, the driver and the population would be exposed.
There are also other regulations for the transport of hazardous goods. For maritime transport, the International Maritime Hazardous Goods Code. By air, the Hazardous goods Regulations of the International Air Transport Association. And finally, the International Regulations for the Transport of Hazardous goods by Rail.
Finally, all companies operating with hazardous goods must have a Safety Advisor to check that the regulations are complied with. The person who holds this position must be proactive and not only supervisory but also propose strategies and plans for implementation.
Transport safety requirements
The transport of hazardous goods entails basic safety requirements. The following aspects should be emphasised:
Goods
The labelling and packaging of goods must be in accordance with ADR regulations. This will certify the identification and avoid problems with customs, refunds or withholding.
Vehicles
Vehicles must comply with a number of safety conditions. For example, in the case of lorries, the trailer must be marked as carrying hazardous goods with a front and rear panel measuring 40 x 30 centimetres and with a black border measuring 15 millimetres. The panel shall also show the hazard identification number at the top and the UN number (category being carried) at the bottom. This signage provides information and ensures safety in transit.
Driver
Driver training is another safety requirement that must be met. In addition to the driving licence and the Certificate of Personal Aptitude (CAP), the ADR Training Certificate provided by the Spanish Department of Transportation - Dirección General de Tráfico (DGT) is required.
Documentation
Obviously, the carriage of hazardous goods requires that the documentation be in order during the journey. The ADR consignment note and instructions must be included in each consignment. The haulier must have liability insurance.
Functions of the Security Advisor
The Safety Advisor of the haulage company, as mentioned above, is a key role. To ensure transport safety, it has the following duties and responsibilities:
● Check that the legislation and regulations for the carriage of hazardous goods are being complied with. To this end, it has to prepare annual reports and report any and all types of incidents, as well as check that staff have the necessary documentation and equipment.
● Advise the haulage company on the implementation of compliance measures. One concrete policy is to establish protocols for company personnel. It should also propose actions for the improvement of procedures.
● Train staff and raise awareness in the company to comply with regulations. This can be done individually, collectively or both.
In short, this professional performs an essential function for companies involved in the transport of hazardous goods to reduce risks.
Risks and precautions
Transporting hazardous goods involves potential risks, for which precautions must be taken. The main threats are fires, explosions and contamination, not only of the goods, but also of the person handling or receiving them. To this end, in addition to applying the Law on Occupational Risk Prevention in general by training staff, protocols are implemented for each class, periodically checking vehicles to ensure that they are in perfect condition.
