Requirement for Building Owners and MCSTs with EV Charging Stations to Implement Additional Fire Prevention and Mitigation Measures
Ministry of Home AffairsSpeakers
Summary
This question concerns Mr Melvin Yong Yik Chye’s inquiry on whether building owners and MCSTs must implement additional fire safety measures for electric vehicle (EV) charging stations. Minister for Home Affairs Mr K Shanmugam replied that these stations have low fire risk due to Land Transport Authority safety standards under Technical Reference 25, which mandate regular maintenance and inspections. He highlighted that stations include automatic electricity cut-offs and require an emergency shut-off switch within 15 metres to facilitate firefighting. Additionally, the existing Fire Code provides for car park compartmentation, ventilation, and sprinklers in high-risk areas to mitigate fire spread. Minister for Home Affairs Mr K Shanmugam concluded that these current provisions effectively address fire risks involving EVs and their charging infrastructure.

6 Mr Melvin Yong Yik Chye asked the Minister for Home Affairs whether there are plans to require all building owners and MCSTs that have electric vehicle (EV) charging stations installed within their buildings to implement additional fire prevention and mitigation measures, in light of the increase in the number of EVs and EV charging stations.
Mr K Shanmugam: Electric vehicle (EV) charging stations are assessed to be of a low fire risk due to the high safety standards imposed by the Land Transport Authority. These standards are stipulated under Technical Reference 25, which takes reference from international safety standards, and also mandates regular maintenance, electrical safety inspection and testing of EV charging stations.
Permitted EV charging stations are designed with automatic internal electricity cut-off should there be a malfunction during the charging process. In addition, the Singapore Civil Defence Force’s Fire Code requires at least one emergency main isolation shut-off switch to be provided within 15 metres of an EV charging station. This can be used to fully shut off the main electrical supply to the charging station in the case of a fire, to facilitate firefighting operations.
Within buildings, EV charging stations are usually installed in car parks. There are existing fire safety provisions in the Fire Code to address the fire risk of car parks, such as fire compartmentation of the car parks from other areas, to prevent fire spread and ensure adequate ventilation for smoke dispersal. Sprinklers are required in basement car parks and car parks of large shopping malls and high-rise buildings. Should there be a fire involving an EV or a charging station, these provisions will reduce the impact of the fire before the arrival of first responders.
