Two-Post Hoist and Corroded Brake Line Under Time Pressure
A 2013 van weighing 2.9 t is on a 3.2 t two-post hoist for a rear brake inspection. The technician has raised it about 1.6 m. One rear hoist arm is under the sill, but the sill is crushed and corroded around the pad, and the arm is not seated flat. The hoist hydraulic hose has a damp patch near the crimp, and there is a 0.5 m oil patch on the floor beside the vehicle. The workshop is busy, the customer is waiting, and an apprentice has brought an angle grinder to cut a seized brake line near the fuel tank. The service manager says to finish it quickly and move it out. No wheel chocks or secondary stands are in place. The van’s brake fluid reservoir is low and the rear brake line is visibly wet.
1. Identify the hazards and immediate actions, and explain how the hierarchy of controls applies.
Read the worked answer
Hazards: Crush or collapse from an unseated hoist arm on a corroded sill; hydraulic hose failure; slip on the oil patch; fire or explosion from grinding near the fuel tank; brake failure from a wet, leaking brake line; and working under a raised vehicle without secondary support.
Immediate actions: Stop the job. Lower the hoist to the ground or to a safe locked height before anyone goes under it. Do not use the angle grinder near the fuel tank. Isolate the hoist if the hose is leaking, barricade the oil patch and contain the spill with absorbent. Report the defect to the supervisor and record it.
Hierarchy of controls: Elimination is best: lower the vehicle and do not work under it. Substitution/engineering controls include using correct lift points, secondary stands and chocks, and repairing the hoist hose. Administrative controls include a stop-work procedure and inspection. PPE is last, not a substitute for a stable lift. The unsafe lift and brake leak must be corrected before work resumes.
2. How would you manage the customer and the service manager's instruction, and what would you document?
Read the worked answer
Managing the instruction: I would refuse to continue under the vehicle and explain the specific risks: the hoist arm is not seated, the sill is crushed, the hoist hose is leaking, and the brake line is wet. The service manager’s urgency does not override the duty to work safely. I would ask for the vehicle to be lowered and moved to a safe bay or for the hoist to be isolated and repaired.
Managing the customer: Explain that the van cannot be driven safely with a leaking brake line and low fluid, and that the lift-point corrosion must be assessed before repairs. Give a clear quote and time estimate rather than promising an unsafe quick fix. Do not release the vehicle as roadworthy without repairing the brake fault.
Documentation: Record the hazard report, photos of the sill and hoist arm, the leaking hose and brake line, the oil spill, the stop-work decision, the supervisor’s instruction and the customer advice. Note corrective actions and who was notified. This protects the customer, the business and the technician.
