H an d ling 4.5.2 DECONTAMINATION Personnel that have been exposed to smoke must change all clothing immediately after the response has concluded. A shower should be taken as soon as possible. Cleaning of personal protective equipment and other equipment used must be carried out in accordance with routines for contaminated equipment. The odour from LIB fires can be intense. After the fire in Ytterøyningen, the odour in firefighter clothing and chemical suits could not be removed by washing, and the clothing had to be destroyed. Consider setting up an agreement with, for example, an incident response company for cleaning of clothing and equipment. 4.5.3 HIGH RISK OBJECTS SECTION 13 Based on what we have of known problem issues associated with LIB, large battery systems (BESS) should be something that the fire services are familiar with. It is recommended that the fire services register larger battery storage installations in accordance with the Fire and Explosion Prevention Act Section 13. The prevention department in the fire services must increase their level of expertise in relation to BESS, so that they can offer good follow-up after any inspections. Some installations will be registered via Planning and Building Services; however, it is known that energy storage facilities are set up without them being registered in a planning application. Many businesses also handle large quantities and volumes of batteries. Car accessory shops, sports shops handling the sale and repair of electric vehicles, contractors, network companies, waste handling companies, scrapyards and similar. The inspection section should be proactive in finding and registering information regarding capacity, safety measures and individual businesses’ internal control routines. Standards can be imposed for certification and control of personnel – however, also in this respect regulations are at present somewhat lacking. Used batteries are a high-risk sport! The authorities are working on establishing control of the entire value chain, i.e. batteries from cradle to grave. Battery modules will be disassembled for resale by both serious, and some less serious, operators. These must be tested according to national standards for control and documentation, but this is unlikely to be done by all companies. A quick search for used batteries online will convince everyone in the fire services of the possible risk factors from used LIB. Firefighting personnel must be aware of the risk object in their area. Registration as a Section 13 object can provide the initiative for drawing up an action plan for the object. Documentation of procedures should be drawn up to comply with regulations in the Working Environment Act. 4.6 ENVIRONMENTAL CONSEQUENCES Contamination to air, water and ground. Contamination to air takes place during all fires; smoke is spread over a large area, but it is diluted significantly. In high temperatures, combustion will also reduce emissions and possibly reduce environmental consequences. It is therefore not always the best course of action, in terms of the environment, to extinguish a fire. More concentrated contamination to water and ground occurs primarily due to extinguishant water. If contamination can be reduced or prevented due to accumulation of extinguishant water, this should be done. What we know about the extinguishant water from battery fires is that it has a raised pH level and contains electrolyte and metals from electrodes, wired networks and circuit boards – but it is unlikely to be any more than in other fires involving modern materials. Smaller batteries should most likely be extinguished to reduce negative environmental consequences. In the case of larger systems, it may be necessary to allow them to burn out, provided the spread of fire can be prevented. Delivery and disposal of burnt out batteries must only via authorised sites. There are only a few companies in the country with this type of authorisation. The fire service will generally not be responsible for delivery to these. See also the section on transport/ADR. 36 DSB THEME / RISK ASSESSMENT AND HANDLING OF FIRE IN LITHIUM-ION BATTERIES
