Sixteen Trainees and a Guillotine Without a Guard
At a government ITI's book-craft unit, two batches of eight trainees work in a 6 × 4 m room. Equipment: a hand-lever guillotine whose blade has three nicks and a weak clamp spring, and whose foot-pedal guard was removed after it jammed; a nipping press with a hairline crack in the casting; a board shear and two corner rounders. Adhesive stock includes a 3 kg tin of spirit-based rubber cement, lid dented, decanted into an open tray on the bench. The room has one exhaust fan, and the window is sealed in winter.
About 4 kg of paper trimmings sits in a hessian sack beside a room heater. The 2 kg CO2 extinguisher was last inspected 20 months ago and its seal is broken. Last week a trainee needed four stitches when the guillotine blade fell while he reached in to remove a cut stack, holding the clamp up by hand. There is no accident register, tools sit on an open rack, and the instructor's view is that "we have always worked like this".
1. Rank the hazards by risk, identify the stop-work items, and give corrective actions with a timeline.

Risk is severity multiplied by likelihood, and one control must be the elimination of the hazard, not a warning.
- Guillotine: unguarded pedal, weak clamp spring, nicked blade. Severity major or fatal, likelihood high, and it has already injured someone. Stop work immediately: refit a guard with a hold-to-run or two-hand control, replace the clamp spring, regrind or replace the blade, and lock and tag the machine until an inspection is signed off.
- Nipping press with a cracked casting: sudden failure under load can throw fragments. Take out of service today; have it inspected and repaired by a competent welder or scrap it.
- Spirit-based adhesive in an open tray in a sealed room: fire and inhalation risk. Move to a metal flammable-liquids cabinet, decant only a day's use into a lidded container, extract at source, and ban heaters and flames.
- Paper trimmings beside the heater: remove the heater, use a lidded metal bin emptied daily.
- Discharged extinguisher: recharge or replace within 48 hours.
Also open an accident register the same day and report to the safety officer.
2. Write a maintenance and inspection schedule for the guillotine and the nipping press, saying what is checked and what is recorded.

Daily, before the first cut: guard and pedal return test; clamp test on a scrap stack; blade checked for nicks by drawing a tissue sheet along the edge; counterweight and lever action; area clear. Weekly: clean and oil guideways and pivot; check clamp pressure on a 50-sheet stack for creep; check back-gauge squareness with a try-square; inspect the blade with a straight edge - regrind at a 0.2 mm nick, because a nicked blade needs more force, creeps sideways and is a safety item, not only a quality item. Monthly: inspect the press casting and screw threads, lubricate, check the shear and corner rounders, and confirm the machine inspection certificate is displayed.
Record every check in a tool log: date, machine, fault found, action taken, who signed. Rules: blade changes by two people with gloves and a carrier, blade guard on whenever the machine is idle, hands never in the clamp zone, no removal of cut stacks while the clamp is held up by hand. A machine without a current log entry should not be used.
3. How should the rubber cement and workshop housekeeping be managed, and what documentation must follow the injury?
Read the worked answer
Rubber cement: keep the 3 kg tin in a locked metal flammable-liquids cabinet away from the heater and any ignition source. Decant at most a day's use into a small, labelled, lidded container; apply from a shallow tray with a brush, not from an open pot. Run the exhaust fan, open the window even in winter, and add a small bench extraction hood. Substitute where the job allows - wheat starch paste or PVA for paper-to-board work; spirit cement is only needed for temporary or self-sealing work. PPE: nitrile gloves, eye protection when decanting, no eating or drinking in the room. Waste: trimmings into a lidded metal bin emptied daily; solvent rags into a self-closing metal can.
Documentation after the injury: entry in the accident register (date, time, name, injury, cause, treatment, witnesses), an incident report with a short root-cause note (unguarded pedal plus a hand in the clamp zone), the corrective action taken, a briefing and re-training record signed by all 16 trainees, and retention of the file for inspection.
