Shift handover: the one-page sheet that stops problems being passed on

At ten to six, the night in-charge is bleary and the day in-charge is still parking his scooter. The handover takes ninety seconds by the time office door. All fine, line two was slow, the rest is running. By nine, line two is scrapping pipe because a barrel temperature was nudged up in the small hours and nobody wrote it down.

Problems passed on at shift change are rarely dramatic. They are small facts lodged in one tired head that walk out of the gate at dawn. A one-page sheet, used properly, catches most of them.

In a live chemical process, a batch outlasts the shift, so the incoming panel operator inherits a reactor mid-cycle. Our page on chemical and specialty chemical plants calls handover the weak point of a live process. Forge lines and press lines rarely stop, so shift change happens with metal moving, as the forging and metal forming notes explain. Moulding and extrusion units see quality drift start at shift change, described for plastic manufacturing.

Food and pharma plants add their own items. A spice or snack unit starting before dawn needs to know whether cleaning-in-place finished. It also needs the metal detector test result and any allergen changeover due. The food processing notes treat these odd-hour starts as routine. A tablet line hands over line clearance status and any batch record entries still waiting for a second signature.

1. Date, line or section, outgoing shift, incoming shift. Outgoing in-charge and incoming in-charge names.
2. Running now: job, part or batch number, quantity done against plan, next changeover and its time.
3. Settings changed this shift: what, from and to, why, and who approved it.
4. Quality: first-off status, lots on hold and where they are kept, rejects segregated, pending inspection.
5. Machines: open breakdowns, maintenance jobs pending, temporary fixes or bypasses still in place.
6. Permits and isolations: open hot work or confined space permits, locks and tags still applied.
7. Safety: near misses, incidents, spills, guards removed for any reason.
8. People: absences, relief moved, trainees on stations, anyone staying on overtime, anyone unwell.
9. Materials: shortages, wrong or new lots loaded, expiry of compound, resin or dispensed material.
10. First three tasks for the incoming shift, in order.
11. Line walk done together: yes or no. Signatures and times of both in-charges.

Sections three, five and six matter most. A changed setting explains tomorrow's rejects. A temporary bypass or a jumper on an interlock can injure someone days later. An open permit or a lock left on an isolator can lead to a machine being started while someone is inside it. What belongs in section three changes with the trade.

• Moulding. Hopper dryer temperature, regrind ratio, cavities blocked off.
• Extrusion. Die gap, puller speed, vacuum tank level, screen pack last changed.
• Forging. Die temperature, lubricant mix, billet heater faults.
• Foundry. Furnace lining condition, ladle preheat, sand moisture, cores in stock.
• Chemicals. Reactor stage, samples awaiting the lab, scrubber and vent status.
• Food. Cleaning-in-place cycle, metal detector check, allergen clean-down.
• Pharma. Line clearance, pending second signatures, status labels on every room.

It should not become a blame file. Entries are facts, written plainly, and nobody is disciplined for honestly recording a problem. It should not grow past one page; a section that keeps overflowing is itself a sign of trouble. And it never replaces the batch record, the machine logbook or the permit register. It points to them.

1. 1

   Outgoing in-charge writes during the last hour

   Not in the last five minutes. Entries made through the shift, especially settings changes, make this quick.

2. 2

   Overlap of ten to fifteen minutes

   Build it into the roster for in-charges and for panel or setter roles. A handover with no overlap becomes a note on a table.

3. 3

   Walk the line together

   Stop at each machine or panel with an open item on the sheet. Look at the held pallet, the changed setting, the tagged isolator.

4. 4

   Incoming in-charge asks, then signs

   Signing means accepting the line as described. If something is unclear, the outgoing person stays until it is clear.

5. 5

   Operators hand over at their own station

   A short version for critical stations: what is running, anything odd, anything changed. The in-charge sheet does not replace it.

• Keep them per line in date order. A binder at the line or a simple digital form, whichever the floor will actually use.
• Plant head reads a sample every week. Five or six sheets picked at random from different shifts.
• Look for items that repeat. The same breakdown, the same shortage, the same bypass. These are the problems the plant has normalised.
• Check signatures and the walk box. Blank walk boxes on one shift point to a habit worth discussing with that in-charge.
• Feed safety items into the incident system. Every near miss on a handover sheet should also appear in the near-miss register.

A plain incident and near-miss reporting form makes the link from section seven easy. Our HR documentation process work sets how long sheets are kept and who can see them.

Start on the line with the most shift-change trouble. Trial the sheet for a month, read a bundle every week, and clear the repeat items you find. Then roll it out. For the wider question of how handover should be organised, read how should shift handover work. Handover sits beside rosters and the skill matrix in our approach to HR in plants.
