When hazardous substances (such as condensate, odorant, waste products) are being transported and an accident happens, these substances may be released unintentionally. This may be harmful to health and to the environment. Hence the transport of hazardous substances must always comply with strict regulations. There are agreements in place with regard to the way in which the transport of hazardous substances must take place by or on the instructions of Gasunie.
VLG (Regeling Vervoer over Land van Gevaarlijke Stoffen (Regulation on the land transport of dangerous substances)) which incorporates the ADR (Accord européen relatif au transport international des marchandises Dangereuses par Route (European Agreement concerning the International Carriage of Dangerous Goods by Road)) is applicable to the usual transport of hazardous substances by or on the instructions of Gasunie.
The operator of a location (office, installation, station) is responsible for ensuring that the transport of hazardous substances is carried out to the correct spot and that the users are instructed in relation to the regulations associated with the transport of hazardous substances. The transporter is obliged to use identification marks so that everyone sees that he is transporting hazardous substances and which category of substances is involved.
The Safety Department must be consulted if there are any questions or if there are cases for which no provision has been made.
