Damaged Racking, Unlicensed Forklifts and a New Mezzanine
A third-party logistics warehouse in Port Klang stores palletised chemicals on five levels of adjustable pallet racking. The site's HIRARC is a two-page table rating every task as 'medium' using likelihood 3 × severity 4; controls listed are 'provide gloves, safety shoes and toolbox talk'. Last month a 1.2-tonne pallet of bagged calcium hypochlorite fell from level 4 after a forklift clipped an upright; the racking has visible deformation at the base plate and no load signs. The warehouse handles 180 container movements a day with 22 forklifts, some operated by agency staff with no licence. The operations manager wants to add a mezzanine picking level to increase capacity by 30% before the peak season. You are the SHO asked to sign off the change.
1. Critique the HIRARC and the 'medium' rating. What hazards are missing?
Read the worked answer
Critique. A two-page HIRARC that rates every task 'medium' is not a risk assessment; it is a label. The matrix has no defined severity or likelihood criteria, so 3 × 4 = 12 is meaningless. A 1.2-tonne pallet falling from level 4 can kill, so severity should be at the top of the scale, not a middling 4. Frequency is also understated: 180 container movements a day and 22 forklifts create repeated pedestrian–vehicle interactions. The controls listed are all PPE and awareness, the weakest controls.
Missing hazards. Racking impact and collapse; incompatible chemical storage (calcium hypochlorite is an oxidiser and can react with acids, organics and other chemicals, with fire or chlorine release); damaged racking and missing load signs; unlicensed agency forklift operators; pedestrian segregation; loading dock falls; manual handling; fire and emergency egress; spill response; mezzanine structural loading.
Required. Redo the HIRARC task by task, covering normal, abnormal and emergency situations, with defined severity and likelihood, exposed groups and existing controls. Then apply the hierarchy: eliminate or separate vehicle and pedestrian routes, engineer rack protection and load signage, control storage segregation, and only then rely on PPE and training.
2. What controls would you require before the mezzanine is approved? Explain management of change.

Before approval. The mezzanine is a management-of-change issue, not a fit-out decision. Require: a structural design and load calculation by a professional engineer; verification of racking and floor capacity; fire safety review (sprinkler coverage, smoke venting, egress travel distance, extinguisher access); building and fire authority approval where required; traffic and emergency plans; and an updated HIRARC covering the new level.
Operations. Segregate forklift and pedestrian routes, fit rack end protectors and column guards, display load capacity signs, restrict storage height below sprinkler deflectors, and train agency staff. Verify forklift licences and authorisations; unlicensed operators must not operate. Provide fall protection and edge protection on the mezzanine, and control manual handling.
Chemical storage. Separate calcium hypochlorite from incompatible materials, provide spill containment and emergency eyewash/shower, and check fire water runoff. The change should not be signed off until these controls are installed and verified. I would record my advice in writing and escalate if commercial pressure overrides safety.
3. Prioritise immediate actions in the next 48 hours and explain how you would verify effectiveness.
Read the worked answer
First 48 hours. Barricade and unload the damaged racking; isolate the bay; inspect all racking for deformation, missing beams, base plate damage and load signs; remove unlicensed forklift operators from service; impose a temporary speed limit and pedestrian exclusion zone; brief the workforce.
Next week. Repair or replace damaged racking to the manufacturer's specification; install rack protectors; mark walkways; verify licences and training; start a rack inspection regime by a competent person; review chemical segregation and spill kits.
Verification. Keep the rack inspection report, licence matrix, training records, photographs and a near-miss log. Track leading indicators: rack damage reports, forklift–pedestrian near misses, speed-limit compliance and housekeeping audits. Report results to the safety and health committee. If the operations manager resists, escalate in writing because the hazard is fatal and the change would increase exposure.
