The Server Room That Smells Like Burning Plastic
You are a first-year technician at a small accounting firm, working under a supervisor who is off-site at a client meeting. At 10:40 am a receptionist tells you the comms cupboard (a converted storeroom, 2.1 m x 1.4 m, no windows, no dedicated air conditioning) smells like burning plastic and the office Wi-Fi has dropped out. You open the door and feel a wall of hot air. A rack-mounted UPS is beeping, three network switches show amber fault lights, and one power board on the floor is warm to the touch with a faint scorch mark near a plug. The office has 14 staff, all of whom are currently unable to process client invoices before a 2 pm deadline. Your supervisor's phone is going to voicemail.
1. Identify the immediate hazards and state, in order, the first four actions you would take in the next five minutes. Justify why each action comes before the next.

Hazards: heat build-up in an unventilated enclosed space; possible electrical fire or overheating component (scorch mark, warm power board, burning smell); UPS fault indication; risk of electric shock if anyone touches damaged cabling; smoke inhalation risk for staff nearby.
Ordered actions:
- Do not touch the equipment. Evacuate and isolate the area - close the cupboard door, move staff away, and keep people out. A burning smell plus a scorch mark is a credible fire risk, and the WHS hierarchy of control puts eliminating the hazard first. Life safety outranks the 2 pm deadline.
- Raise the alarm and notify - tell the office manager, call the supervisor (leave a voicemail if needed), and if there is any sign of flame or sustained smoke, call 000 and trigger the evacuation procedure. Document the time.
- De-energise only if it is safe to do so - if the main switch or circuit breaker for the cupboard is clearly identified, accessible and not hot, switch it off. Do not reach into the rack or pull individual plugs from a warm power board.
- Preserve the scene and record - photograph the scorch mark and fault lights from a safe distance, note the UPS alarm pattern, and log everything. This protects the firm's insurance position and the incident investigation.
Reasoning: each step reduces the chance of harm before the next is attempted. Restoring Wi-Fi is a recovery task, not an emergency task, and should only occur after the area is declared safe and the cause is identified.
2. The office manager says, 'Just move the power board and reset the UPS so we can hit the 2 pm deadline.' Write the response you would give, and explain the WHS and professional reasoning behind it.

Response: 'I can't do that. There's a scorch mark and a burning smell, which means something has already overheated. If I reset the UPS and re-energise the circuit, I could start a fire in a room with no windows and no ventilation, and there are 14 people in this office. I've isolated the cupboard and called [supervisor] and the office manager. I can help you contact clients about the deadline, but I won't restore power until an electrician has inspected it.'
Reasoning:
- Duty of care: under WHS law, workers must take reasonable care for their own and others' safety and must not wilfully place others at risk. Re-energising a circuit with a visible scorch mark is a foreseeable risk of serious harm.
- Hierarchy of control: elimination (isolate the circuit) beats administrative workarounds (reset and hope).
- Competence boundary: a first-year technician is not a licensed electrician and should not diagnose or repair fixed wiring.
- Escalation: the supervisor is unreachable, so the next most senior person and the emergency procedure take over; the voicemail and written log create a record.
- Commercial framing: a missed deadline costs a client relationship; a fire costs lives and the business. Frame the refusal as protecting the business, not obstructing it.
