Stop and escalate
Smoke, rapid heating, swelling, hissing, electrolyte leakage, arcing or a damaged battery requires immediate isolation of the area and activation of the site emergency plan.
Design the charging area
- Dedicate and mark the area; protect chargers and batteries from vehicle impact.
- Provide ventilation, electrical protection, lighting and emergency arrangements suited to the battery chemistry and charging rate.
- Keep combustibles and incompatible activities away according to the approved assessment.
- Make isolation points, alarms, exits and emergency contacts visible and accessible.
Control each charging event
- Authorise operators and use the correct charger, connector, voltage and charging profile.
- Inspect cables, plugs, housings, battery condition and equipment before connection.
- Park securely, switch off, apply the site isolation steps and route leads to prevent damage or trips.
- Do not improvise repairs, adapters, extension leads or charging settings.
Respond to abnormal conditions
- Stop charging and isolate only when safe if there is heat, swelling, odour, smoke, arcing, leakage, impact damage or repeated charger faults.
- Keep people away and follow the site emergency plan; battery incidents may re-ignite and need specialist advice.
- Use spill response appropriate to the electrolyte and only with trained personnel and correct PPE.
- Quarantine damaged batteries in the approved location and obtain competent assessment before reuse or disposal.
Records and review
- Battery and charger identification, inspection result and reported defects.
- Charging faults, temperature alarms, impacts, spills and emergency actions.
- Maintenance, repairs, disposal documents and manufacturer bulletins.
- Trend repeated faults by truck, battery, charger, shift and location.
Questions for the supervisor review
- Is every charger matched to the approved battery and vehicle?
- Can an operator recognise and escalate heat, swelling, leakage or damaged connectors?
- Are damaged batteries prevented from returning to service?
- Has the emergency plan been tested for the battery chemistry actually present?
Useful measures
Use your own verified history and risk profile rather than a generic target. Review these measures together:
- Pre-use and connector defects
- Charging interruptions and fault codes
- Battery heat, damage, spill or fire events
- Overdue charger and battery maintenance
Turn the review into action
Record the exact location, observation, immediate control, risk, accountable owner, due date and closure evidence. Review repeated or overdue issues with management and the competent specialist for the subject.

Work the problem from evidence to closure
Practice situation
Charging is taking place beside general storage with damaged leads and no controlled exclusion area. The useful response is not a generic target or a tick-box answer. Start by defining the exact event, location, item, time period and decision owner so that another reviewer can reproduce what happened.
Decision path
Stop charging, isolate the defective equipment and have the location assessed for ventilation, ignition and emergency controls. Record assumptions before changing the process. Compare the proposed control with the current condition, test it on a limited scope where appropriate, and define the condition that would require work to stop or management to escalate.
Evidence pack
Charger inspection, battery identification, defect record, authorised repair, area inspection and training. Keep the source record with the action rather than copying only a summary into a presentation. A complete pack should show who reviewed the information, what was excluded, the date of the decision and proof that the action was later checked.
Supervisor walkthrough
- Observe the work at the location and ask the operator to explain the normal sequence.
- Compare the observed sequence with the written standard and system record.
- Separate an isolated exception from a repeated condition by checking recent history.
- Agree one immediate control and one corrective action with a named owner and realistic date.
- Return after implementation and verify the result with evidence, not verbal confirmation.
Common failure to avoid
Do not close the review with “team advised” or “monitor closely.” Those statements do not identify a changed control, accountable owner or effectiveness check. A useful closure states what changed, where it changed, when it was checked and what result would reopen the issue.
