Health, safety and wellbeing for Battery Pack Makers: fire risk in cell storage, charging and testing
One careless act with cells, a metal tool or a charger can start a fire. Safety in a pack shop is built from small, repeated habits at the store, the welding bench and the overnight test area.

The danger in this work is quiet. A loose metal tool lies near open cell terminals. A damaged cell goes back on the shelf instead of to a marked bin. Spot welding is done with long sleeves of dust and without eye protection because the shift is behind. The charging area runs overnight with one person responsible for several racks, and nobody has told him what to do if a pack heats. A fire in this setting spreads fast and hurts the person nearest to it.
Good looks like a small set of rules that everyone, including the owner, follows. Cells are stored and moved by a fixed method, damaged cells have a marked bin, tools near open terminals are controlled, and the charging area has a defined layout and an overnight check list. Everyone knows the first three actions if a pack heats up, and the drill is practised, not read.
How to set it up
1. Walk the cell journey from store to dispatch
Follow a cell through receiving, grading, welding, assembly, charging and test with a supervisor. Mark each point where a short circuit, a dropped cell or heat could occur.
2. Write short rules for each point
For the store, welding bench, charging racks and test area, write the rules on one card each. Cover tools near terminals, gear, damaged cells, rack spacing and who may be present.
3. Set up the damaged cell and heat response
Provide a marked bin, a clear route and equipment for the first response. Agree the three first actions and who makes them. Our health and safety support can help turn this into a drill.
4. Practise the response on every shift
Walk each shift through the plan, including the overnight crew. Ask each person what he would do first and where the exit is.
5. Check the rules daily and record near-misses
Give each supervisor a short check list, and record any heat, drop or spark the same day. Read the record at the weekly meeting.
Check these first
Before changing anything, find out what is true today. These take an afternoon and use your own records.
- Walk the store and charging area and count loose metal tools near open cells.
- Read the last month's incident or near-miss notes and see whether any involved heat or a dropped cell.
- Ask three overnight staff what they would do first if a pack heated up.
- Check whether damaged cells have a marked place and whether it is used.

Questions owners ask
Pick one supervisor per shift who holds the daily checks, and keep the owner as the person who reviews the record each week. This keeps safety from depending on one person's memory.
Define who is present, what they check and when, and what they do if a rack shows heat. Do not leave a single new hire alone with several racks.
Yes, briefly. Anyone who enters the production area should know the rules and the exit route, and visitors should be briefed at the gate.
