Sparks, Thinner and a Seeping Jack: A 5S Walk-Through in Bay 2
At a four-bay car and two-wheeler service outlet in Nashik, the supervisor walks into bay 2 at 11:20 a.m. and finds a first-year apprentice cutting a rusted exhaust clamp with a 100 mm angle grinder whose guard has been removed. The apprentice wears cotton gloves and safety glasses, not the face shield kept in the store. Sparks fall within 1.5 m of an open 5-litre can of thinner and a heap of oily cotton waste. Under the car in bay 3, a hydraulic trolley jack is seeping oil, and a 40 cm slick crosses the walkway. A second technician is blowing brake dust off a drum with the compressed-air gun at 6 bar. The 5S board still shows last week's red tags, three torque wrenches lie on the floor beside the ramp, and the fire extinguisher near bay 2 carries a service tag dated 14 months ago. Nobody has been hurt. The apprentice says, 'We always work like this before an audit.'
1. Rank the hazards you can see and state the control you would apply to the two most serious, justifying each control against the hierarchy of controls.

Ranking (highest risk first): (1) grinder with the guard removed, sparks near open thinner - fire, flash and amputation risk; (2) oily jack plus a 40 cm slick on the walkway - slip, fall and jack collapse; (3) dry blowing of brake dust at 6 bar - inhalation and eye injury; (4) extinguisher 14 months past service; (5) 5S breakdown on the floor.
Grinder and thinner. Elimination and substitution come first: stop the job, move it out of the bay and use a cold method such as a hacksaw or bolt cutter, or a shear. If cutting is genuinely unavoidable, move the thinner and waste to a flammable store, refit the guard, use a hot-work permit, a fire blanket and a 30-minute fire watch after the cut. PPE - face shield, leather apron - is the last layer, not the first defence.
Jack and slick. Eliminate at source: take the jack out of service, replace the seal, and put a drip tray under it. Then clean the spill with absorbent and barrier tape the area before work restarts. Cleaning only, without fixing the leak, just moves the hazard to tomorrow.
Brake dust must be wet-cleaned or vacuumed with a HEPA unit, never blown into the breathing zone.
2. Apply 5S to what you saw and describe the follow-up you would run over the next two weeks, with owners and checks.

Sort (Seiri): red-tag the unguarded grinder, the leaking jack, the compressed-air gun used for dust and the expired extinguisher, and move them to a locked quarantine area. The thinner belongs in the flammable cabinet, not on the floor.
Set in order (Seiton): torque wrenches go back to the shadow board with their calibration labels visible; each bay gets a marked cutting area with a fire blanket point; the extinguisher gets a floor marking so it cannot be blocked.
Shine (Seiso): clean the slick, degrease the ramp, and add a daily 10-minute end-of-shift clean-up with a signed checklist.
Standardise (Seiketsu): write a one-page bay-start checklist covering guard fitted, PPE worn, no flammables in the bay, extinguisher access clear, spill kit stocked, and display it at each bay.
Sustain (Shitsuke): a weekly 5S audit with a simple score sheet, red-tag review every Friday, and a named owner per zone - for example, the bay supervisor for cutting, the storekeeper for flammables. Review the score at the tool-box talk so the fix is visible, not just filed. The extinguisher needs a monthly visual check recorded on the tag and an annual service by an authorised agency.
3. Nothing happened this time. What should the workshop do with this near miss, and how should the apprentice's remark be handled?
Read the worked answer
Treat it as a near miss, not as a non-event. A near miss is free information about a control that has already failed; the injury is simply the next step in the same chain.
Immediate: record it on a near-miss form the same day - time, bay, people involved, what failed, what could have happened, and the immediate correction. Photograph the area before it is cleaned. Inform the workshop manager.
Short term: hold a tool-box talk the next morning using this event, not a generic video, and re-brief the hot-work and spill rules. Check whether other bays have the same pattern - guard removal and a leaking jack are rarely one-off.
Long term: review the job safety analysis for cutting, add a permit, and add a check item to the supervisor's opening round. Track whether reports rise and injuries fall; a rise in near-miss reports is usually a good sign of trust.
The remark should not be punished as a confession. 'We always work like this before an audit' says the audit is the real driver, so the supervisor should answer with the standard, not with blame: the standard applies on every shift, and the person who reports a problem will not be penalised. Publish the fix so the apprentice sees that reporting changed something.
