Environmental protection and sustainable working practices
This domain tests how you prevent pollution and manage waste and resources lawfully during plant operations - the difference between a minor spill that is contained and a prosecution.
Core rules
- Duty of Care (Environmental Protection Act 1990 s.34) - waste is stored safely, transferred only to a registered carrier, described accurately on a transfer or consignment note, and recorded. Keep waste transfer notes for 2 years and hazardous waste consignment notes for 3 years.
- Waste hierarchy: prevent, reuse, recycle, recover, dispose. Segregate skips (inert, wood, metal, general, hazardous) to keep material recoverable and avoid contaminating loads.
- Oil storage - tanks over 200 litres are bunded to 110 per cent of capacity with the fill point inside the bund and no drain connection. Refuel over a drip tray at a designated point, at least 10 m from a watercourse and 50 m from a well or borehole.
- Spill response: stop the source, contain with granules or a drain seal, protect drains and watercourses first, never hose a spill away, and report it immediately.
- Dust, noise and emissions - suppression on cutting and loading, correct engine mode, no unnecessary idling, DPF regeneration only where permitted, and considerate working hours near receptors.
- Protect what is fixed: tree root protection zones, watercourses, protected species and archaeology - stop and report sightings rather than working around them.
Worked example
A 20-litre diesel spill occurs at the refuelling point beside a surface water drain. You stop the pump, deploy the spill kit, cover the drain inlet, use granules on the fuel and contain the contaminated absorbent as hazardous waste. Reasoning: fuel reaching a surface water drain is a reportable pollution incident, so protecting the drain takes priority over clearing the fuel on the surface.
Traps that cost marks
- Describing any oil as "biodegradable" and treating it as harmless.
- Washing out buckets or mixers into drains or watercourses.
- Burying or burning waste on site - both are offences, not shortcuts.
