Adhesive Vapour, a Failed Fan and a Frayed Extension Cord
On a Tuesday morning, 14 operators are pressing fused interlining onto 800 jacket fronts using a solvent-based spray adhesive at an open pressing table. The local exhaust fan has not worked since the previous shift; the supervisor says it is 'only a small job' and asks the team to finish before lunch. By 10:30, three operators report headache and dizziness, and one has spilled adhesive near a daisy-chained extension board with six plugs; its cable is frayed and lying in a puddle of machine oil. Rolls of fabric block the side exit, and the first-aid box is empty. Production pressure is high because the export container leaves tomorrow. The line has no written safety data sheet for the adhesive on the floor.
1. List the hazards in this scene and the immediate actions you would take before production continues.

Hazards:
- Solvent adhesive vapour with failed local exhaust. Headache and dizziness are acute exposure symptoms, not normal tiredness.
- Electrical danger: six plugs on a daisy-chained extension, frayed cable, oil and water on the floor. This is a shock and fire risk.
- Blocked side exit and empty first-aid box: delayed evacuation and no treatment.
- No safety data sheet on the floor: exposure controls and first aid for the adhesive are unknown.
Immediate actions: stop the spray operation and move workers to fresh air; send the three symptomatic workers for medical assessment; isolate the extension board at the mains and tag it out; do not touch the frayed cable; clean the spill with suitable absorbent; clear the exit and fabric rolls; restock first aid; inform the safety officer and manager.
Do not restart until ventilation is restored and the electrical defect is repaired. The container date does not make an unsafe condition acceptable.
2. Apply the hierarchy of controls to the adhesive vapour and the electrical risk, giving specific examples.

For the adhesive vapour:
- Elimination: stop spray adhesive if the interlining can be bonded by heat press or applied as a film.
- Substitution: replace the solvent adhesive with a water-based or low-solvent product after checking the safety data sheet and bond performance.
- Engineering: restore local exhaust at the table, enclose the spray area, or use a spray booth.
- Administrative: limit exposure time, rotate operators, train on the data sheet, housekeeping and spill response.
- PPE: respirator and gloves only as a last line, not instead of ventilation.
For the electrical risk: remove the daisy chain; use one appliance per socket or a proper distribution board; repair or replace the cable; keep oil and water away; use an RCD-protected circuit. PPE is last because it depends on fit and correct use, and the dizziness shows earlier controls have already failed.
3. What should be recorded and reported, and how should the operator respond to the supervisor's instruction to finish before lunch?
Read the worked answer
Record the date and time, area, ventilation failure, symptoms and names for confidential medical follow-up, electrical defect, blocked exit, missing first-aid stock, missing safety data sheet and the production lot affected. Report to the safety officer, factory manager and safety committee; report the electrical danger and occupational illness through the factory's required channels.
The operator should refuse to continue the spray task in the unsafe condition and state the specific reasons: exhaust failure, symptomatic workers, live electrical hazard and blocked exit. Ask for the job to be moved to a ventilated area or rescheduled. If the instruction is repeated, escalate to the safety officer or manager. 'Finish before lunch' cannot override immediate danger; production can restart after controls are in place.
