Advice on storage practices for flammable products without hazard pictograms

According to the UN Recommendations on the transport of dangerous goods (UN RTDG), there may be an exemption for flammable products with a flash point below 60°C and above 35°C, specifically those that pass the test in Part III, Section 32 (L.2). These products, often viscous substances, may not display the typical hazard pictograms for flammable materials because of this exemption. As a result, under regulations such as VLAREM in Flanders (Belgium), they can or must be stored outside the areas designated for substances bearing flammable pictograms.

This situation has two important consequences for storage management:

1) Space planning: facilities may find that they have allocated insufficient space to store these non-labelled flammable products safely. Effective space management must take these exemptions into account to ensure that all flammable products, regardless of whether they carry pictograms, are stored safely and in compliance with regulations.

2) Safety measures outside designated areas: depending on the results of the risk assessment, it may be necessary to implement fire and explosion safety measures outside the areas traditionally designated for storing flammable products with hazard pictograms.
