A Broken Needle, No Guard and a Compliance Audit in Six Weeks
A stitching unit with 24 single-needle lockstitch machines runs two shifts. During a shift change a trainee was threading her machine, which had had its needle guard removed three weeks earlier because the guard 'slowed threading down'. The needle broke: one fragment lodged in the feed dog, another struck her cheek below the eye. She was wearing no eye protection and the unit does not issue any. The same day the supervisor found a 1.5 m long oil patch near the pressing table, a loose V-belt guard on the motor of machine no. 7, an unlabelled bottle of kerosene beside the thread trimmers, and a compressor in the corner generating 92 dB(A) at the operator's ear position. The first-aid box has no contents list, there is no incident register, and there is no PPE budget. The owner says the unit is 'small' and that the trainee 'should have been more careful'. A buyer's social-compliance audit is due in six weeks.
1. Rank the hazards found by risk and justify the ranking. Which one do you fix before the shift ends today?
Read the worked answer
Rank by severity × likelihood, not by how visible the hazard is.
| Rank | Hazard | Why |
|---|---|---|
| 1 | Missing needle guard + no eye protection | Severity: eye/face injury, possible permanent loss of sight. Likelihood: needle breakage is routine, several times a week per machine. Highest combination in the unit. |
| 2 | Loose V-belt guard on machine no. 7 | Severity: entanglement of fingers or hair, amputation risk. Likelihood: moderate but constant while the motor runs. |
| 3 | Oil patch near pressing table | Severity: slip and fall against hot press or hard floor; also a fire load. Likelihood: high - 1.5 m is a whole walking line. |
| 4 | Unlabelled kerosene bottle | Severity: poisoning if mistaken for a drink, fire if near sparks. Likelihood: lower, but cheap to fix. |
| 5 | 92 dB(A) compressor | Severity: hearing loss, but chronic, not acute. Likelihood: certain for the nearest operator, so it still needs action - just not the same day. |
| 6 | Paperwork gaps (first aid, register, PPE budget) | These cause no injury by themselves, but they are what the audit will score, and they prove you have no system. |
Fix before the shift ends: machine no. 7 is locked out until the belt guard is refitted, and every machine is checked for a needle guard. Any machine without one is tagged out. That is a matter of hours, not a project.
2. The owner wants to 'just issue goggles' to the operators. Why is that the wrong first move, and what control package would you actually apply?
Read the worked answer
Because PPE is the weakest control in the hierarchy and is being used to paper over an engineering failure. The eye injury was caused by a missing guard, not by missing goggles. If you issue goggles and leave the guard off:
- the guard also prevents fingers and hair being drawn into the needle area, which goggles do nothing about;
- operators will remove goggles because they fog, scratch and slow threading - so compliance will be 50% at best, and you will have spent money for nothing;
- a compliance auditor will treat PPE-only as evidence that you could not eliminate the hazard, and will ask why the guard was removed.
The control package, in order:
- Eliminate / engineer: refit needle guards on all 24 machines (a ₹250 part), fit a fixed or interlocked belt guard, fit the compressor with an acoustic enclosure or move it outside the workroom, replace the kerosene bottle with a labelled, lidded solvent container in a metal cabinet.
- Substitute: switch to pre-threaded or self-threading needles and a needle-threader tool so operators are not putting fingers near the eye of a needle at all.
- Administrative: a written broken-needle procedure - stop, find and account for every fragment (use a magnet), record machine number, operator, time, and confirm all pieces are collected before restarting. This one procedure is asked for in nearly every compliance audit and costs nothing.
- PPE, last: polycarbonate goggles for threading and trimming tasks, ear plugs for the compressor area, and a signed issue record. PPE protects against what the engineering has not yet removed.
Also deal with the owner's framing. 'She should have been careful' is a blame response; the trainee was using a machine that had been deliberately made unsafe by someone senior. Record that in the incident report, because hiding it is what turns a small injury into a legal problem.
3. The audit is in six weeks. What documented systems would you put in place, and where would you spend a limited budget first?
Read the worked answer
Documents the auditor will look for:
- Incident register (date, machine, injury, action taken, signature) - start it from this incident, not from a blank page.
- First-aid box with an itemised contents list, an expiry check date, and at least two trained first-aiders per shift named in writing.
- Hazard and PPE matrix: task → hazard → control → PPE.
- Machine maintenance log showing guard checks, needle changes, and lubrication.
- Training records with the trainee's signature and the trainer's name - evidence, not a claim.
- Chemical register and labelled containers.
- Waste and housekeeping schedule with named responsibility.
Budget order - spend on the things that remove injury, not on files:
- Needle and belt guards for 24 machines (highest risk, lowest cost, huge audit weight).
- Lockable chemical cabinet and labels.
- Goggles and ear plugs with an issue register.
- First-aid supplies and a bookkeeping system.
- Printer, files and signage last - the auditor will notice a spotless file folder and a missing guard.
Time plan: weeks 1–2 engineering, week 3 procedures written with the operators (so they are actually used), weeks 4–5 training and records, week 6 internal mock audit, and correct every finding before the buyer arrives. Tell the owner the honest thing: an auditor is not looking for a perfect unit, but for a unit that finds and fixes its own faults. That story is much easier to defend than 'the trainee should have been careful'.
