Section 5-13. Containers and pipes

Containers that are used at the workplace for chemical substances or mixtures classified as hazardous pursuant to the Regulations of 16 June 2012 No. 622 relating to the classification, labelling and packaging of chemical substances and mixtures (CLP), containers used to store such substances or mixtures and visible pipes that contain or transport such substances or mixtures, shall be marked with the relevant hazard pictogram in accordance with the said regulations, cf. Regulation (EC) No. 1272/2008 Annex V.
The marking shall be placed on the visible side(s) and be in the form of signs, self-adhesive labels or painted symbols.
Pipelines shall be marked with an arrow to indicate the direction of flow and with a warning sign to show what substances or mixtures the pipeline is carrying. Pipelines shall also be marked with colour codes.
The marking used on pipelines shall be in an easily visible position near the most dangerous points such as valves, flanges or couplings, and at appropriate intervals.
The first paragraph does not apply to containers used at the workplace during short periods or containers with frequently replaced content, on the condition that satisfactory alternative action is taken, particularly in terms of information and/or training, that ensures the same level of protection. The marking in the said first paragraph may be:
  • -
    replaced by warning signs laid down in Section 5-7 (2), using the same pictograms or symbols. If there is no suitable safety sign in Section 5-7 (2) the relevant hazard pictogram must be used, as stipulated in the Regulations of 16 June 2012 No. 622 relating to the classification, labelling and packaging of chemical substances and mixtures (CLP), cf. Regulation (EF) no. 1272/2008 Annex V.
  • -
    complemented with additional information, such as the name of and/or formula for the hazardous substance or mixture and information about risks.
  • -
    for transport or moving of containers in the workplace, complemented or replaced by signs used throughout the EEA for transport of hazardous chemicals or mixtures.
