Hidden Fire Risk: lithium-ion batteries in vaping devices

Mark Littlejohns

Vaping devices, like many modern electronic products, contain rechargeable lithium-ion batteries, which can present a significant fire risk if damaged, poorly stored, incorrectly charged, or involved in thermal runaway.

A reminder for fire risk assessors:

It is important for fire risk assessors to ensure that lithium-ion battery hazards should be clearly identified and recorded within fire risk assessments.

Particular attention should be given to:

  • Storage and charging arrangements for lithium-ion batteries
  • Quantity and type of battery-powered devices on site
  • Separation from combustible materials
  • Ventilation and fire detection in storage areas
  • Staff awareness of safe charging practices

Retail premises such as vape shops, e-bike retailers, electronics stores, and repair workshops may hold significant quantities of lithium-ion batteries and associated charging equipment. These should always be considered as a specific ignition and fire-load hazard during the assessment process.

As lithium-ion powered devices become more common in both commercial and domestic settings, recognising and documenting these risks is essential to ensure appropriate control measures are in place and to reduce the likelihood of similar incidents in the future.
