A safety routine fails when it lives only on a poster. It works when each check has a name beside it, a time against it and a place to write the result. That is as true for a laminator-bay as for a wind-blade lay-up shed.
This guide lays out who checks what, and when, for plants making modules, mounting rails, inverters, junction boxes, battery packs, blades and storage containers. It describes practice, not a rulebook. For the sector overview, open the solar and wind hardware hub, and our safety and wellbeing work covers the people side.
Know which hazard lives where
A module line and a pack hall do not share the same risks. Write them down area by area before you assign any check.
- Module line: hot laminator plates, glass edges, heavy sheet lifts, cell-string breakage, forklift traffic near the frame-fitting station.
- Pack and storage hall: shorted cell terminals, metal tools on live strings, dropped cells, unattended chargers, cycler-hall alarms at night.
- Inverter bench: soldering fume, hipot test cage, capacitor discharge, heavy heat-sink handling.
- Mounting-rail shop: roll-forming pinch points, sharp zinc-coated edges, welding fume, crane slings.
- Blade and tower shop: resin and gelcoat handling, grinding dust, work at height on moulds, flange bolt-torque rigs.
- Junction-box and connector plant: moulding press hot parts, crimp dies, trimming blades, potting compound skin contact.
Who checks what, and when
- 1
Shift-start walk (shift-lead, ten minutes)
Walk the bay. Look at guards, floor, aisles, escape routes and extinguisher access. Confirm the glove stock, eyewear and hearing protection are at the bench. Initial the shift-start card.
- 2
Machine-side check (operator, before first run)
Each operator confirms the guard, emergency stop and light curtain on their own machine before the first cycle, then marks the card. No tick, no start.
- 3
Mid-shift touch (shift-lead)
One look at the cycler-hall, the charging store or the test cage. Note any alarm that rang and who attended it. Night shifts do this twice.
- 4
Weekly sweep (safety-nominee from the floor)
A rotating operator, not a manager, walks the plant with a checklist and photographs one thing worth fixing. This builds ownership and catches what supervisors stop seeing.
- 5
Monthly review (works manager and HR lead)
Read the shift cards, the near-miss slips and any injury entries. Pick one pattern and one fix. Tell the floor at the next toolbox talk.
The near-miss slip
Near misses are cheap warnings. Give every bay a pad of slips and a box. The slip needs only four lines: what happened, where, when and what nearly followed. Do not ask for names. Count the slips each month, not the blame.
A pack hall that records a dropped cell and a spanner left on a busbar has two lessons before anyone is hurt. A module line that records three glass-edge cuts at the same station has a layout problem. The slips are the evidence.
Induction before first solo
A new hand should not touch a stringer, spot welder, resin table or test cage until a short induction is done. Cover the area hazards above, the emergency routes, the protective kit and who to shout for. Then pair the joiner with a buddy for the first shifts. See safety notes for cell and pack assemblers lay out one structure, and the container storage builders page does likewise for cabinet builds.
When output pressure bends the routine
Routines slip at month end, when a dispatch truck waits at the gate. The stringer-room supervisor skips the shift-start walk. A spot-welder keeps working with a loose guard because the pack order is behind. Decide in advance that the card is never skipped, however late the truck is. Say it at a toolbox talk. Then back it, by letting a shift-lead stop a line without asking anyone first.
Watch for the quieter slip too: the glove shelf that stays empty, the eyewash bottle past its refill day, the extinguisher blocked by pallets of backsheet rolls. These are cheap to fix and tell the crew whether the plant means it.
What a night shift needs extra
- A named on-call engineer whose mobile number is chalked on the shift board.
- A rule that nobody works a rack or test cage alone for a full shift without a check-in call.
- Tea breaks actually taken, on a bench well away from the machine.
- Lighting checked at shift start, since a dim aisle hides a coiled hose.
Records that tell you something
- Shift-start cards, filed by bay, for the last three months.
- Near-miss slip counts by area and month.
- Induction sign-offs, showing who ran each one and on which day.
- Training dates for first aid and fire response, with the names trained.
- Open actions from the monthly review, each with a holder and a due day.
Keep them plain. A ring file hung at the bay beats a database nobody opens. If you later want these in one place, an HR reporting set-up can hold them.
Start with one bay
Choose the bay with the highest consequence, usually the cycler-hall or the lamination bay. Run the shift-start card there for a month. Add the weekly sweep in month two. Spread to other bays once the habit holds. For help with drafting the cards and the induction, send the plant's particulars via the requirements wizard.
