WARNING PANELS Alongside the Hazard Diamond, an orange Warning Panel is required showing the UN Number and the Emergency Action Code. Further Transport Marking Requirements
Transport Index (TI)
The Transport Index is determined by taking the maximum radiation level one meter from an undamaged package. The TI can be calculated by determining the maximum radiation level at one metre from all the external surfaces of the package as measured in millisieverts per hour and multiplying this figure by 100. For example, a TI of 0.2 would indicate that, at 1 meter from the labelled package, the radiation dose rate should be no more than 0.002 mSv/hr.
UN NUMBER Dangerous goods are given a four-digit UN number which identifies the substances and helps the emergency services obtain information quickly. The four-digit UN number is required to be displayed at the bottom of an orange-coloured panel (sometimes called and ADR Plate) on tanks, tank containers and vehicles carrying dangerous goods in bulk. Some hazardous substances have their own UN numbers while in other cases groups of chemicals or products with similar properties receive a common UN number.
EMERGENCY ACTION CODE The three-character code on the top of the panel is the Emergency Action Code (EAC). This must be used on all GB registered road and rail vehicles that carry dangerous goods on domestic journeys within the UK rather than a two-digit International ADR marking, which uses Hazard Identification Numbers (HIN), also known as the Kemler Code. It quickly tells the Emergency Services how to deal with a spill. The EAC is interpreted by the Emergency Action Code pocket cards - shown below. The first character in an EAC represents the firefighting extinguishing media which will best control a chemical fire. The second character denotes hazard controls for people and the environment to keep the situation as safe as possible (BA stands for Breathing Apparatus and LTS refers to a Liquid Tight Suit). The 3rd character, if there is one, will always be āEā ā this means that it is a Public Safety Hazard.
