Tank markings for hazardous substances
Process identification is an important part of safety signage. If hazardous substances are present, the emergency services must be able to identify them immediately. Tanks and pipes must be marked in accordance with European directives and Dutch occupational health legislation. Information such as tank capacity, tank number, GHS (Globally Harmonized System of Classification and Labelling of Chemicals) symbols and the NFPA (National Fire Protection Agency) hazard diamond are valuable information for operators, maintenance departments and emergency services; these must be included in the marking of a tank.
NFPA diamond, GHS symbols in accordance with CLP legislation
At onshore locations, Blomsma Signs & Safety often uses the NFPA diamond for communication purposes. In the event of a fire, the NFPA diamond informs emergency services about the properties of the substance being stored or transported. We also use the mandatory GHS safety symbols in accordance with the CLP (Classification, Labelling and Packaging) legislation and in most cases the UN substance identification number and the hazard identification number known as the Kemler code.
Location, design and size of the markings
Determining the location of the markings is particularly important for onshore locations. In accordance with legislation, it should be on the tank itself or at another dominant location if marking on the tank is impossible or if legibility is affected by the position of the tank in a tank pit. Visibility and readability are the primary factors on deciding the placement of a marking. Because Blomsma Signs & Safety has its own facilities for manufacturing the signs, specific layouts are available for production within a short amount of time.
Individual or overview markers
Individual tank markings on the tank are legally required. Individual markings can also be applied combined with the techniques that we use for overview signs. We then make a three-dimensional overview of a tank pit and add the tank numbers and hazard symbols. Which substances are present at which locations can then be seen from a single place. Overview signs provide additional safety. They are essential in situations where it is impossible to read the installed markings on a tank from a safe position.
