Afterwards, he was sent to hospital for proper examination. So far, there was no serious or permanent injury sustained during the incident.
Q: Why did the battery explode?
A: It was revealed that the battery cell caps were not remove during the charging process, which resulted in a build up of gas causing an "explosion".
Below Photo shown of the battery after explosion:

- Only competent persons are allowed to enter the battery charging room/area.
- Ensure that all risk assessments are regularly checked and updated.
- Always wear proper PPE (e.g eye and face protection) while entering the battery charging room/area.
"Battery charging room/area must be designed for the purpose. Correct ventilation, warning signs, NO smoking signs, eye wash station, spill kit, fire equipment and emergency plan MUST be all in place. Shelving where the batteries are charged and surface should be non-porous in order to prevent it becoming sodden and enable correct clean up of spills.
