Waste Management and Premises Design
This domain tests how premises and waste flows are designed to stop contamination, and the legal duties attached to waste. Questions often ask you to identify a design fault in a described layout or to state what must accompany waste when it leaves the site.
Premises requirements
- Linear workflow - delivery, storage, preparation, cooking, service, with no crossing back from dirty to clean. The principle is "no cross-flow" of food, equipment, waste or people.
- Surfaces must be smooth, impervious, washable, non-toxic and light coloured so dirt shows. Floors should be non-slip, with coving at wall junctions and drainage where needed.
- Ventilation and lighting - adequate extraction to control heat, steam and condensation; shatterproof covers on lights above food.
- Handwash basins - dedicated, with hot and cold running water, soap and drying, and never used for equipment or food washing.
- Separate areas for raw and ready-to-eat preparation, or separation by time with cleaning between.
- Toilets must not open directly into food rooms, and must have their own handwash basin.
Waste management
- Segregate waste at the point of production: food waste, packaging, glass, waste cooking oil.
- Use lidded bins, ideally foot-operated, emptied frequently and never allowed to overflow.
- Keep bins away from food preparation and store external bins on a hard, washable area away from doors and vents.
- Waste contractors must be registered and authorised; a waste transfer note or duty-of-care record must accompany each transfer and be kept for at least two years.
- Never put waste into a sink or drain if it can be avoided; grease traps must be maintained.
- Sharps and glass must be disposed of safely and separately.
Worked example
A bakery lays out its new unit with a doorway where staff carry raw dough waste past open trays of finished pastries to reach the external bin. Reasoning: this is a classic cross-flow fault. Waste and people carrying it should never pass through or next to exposed ready-to-eat food. The remedy is to reroute the waste stream, relocate the bin, or install a separate exit, and to schedule bin runs outside production times.
Traps that cost marks
- Describing premises as "clean" rather than naming impervious, washable surfaces and a linear flow.
- Forgetting the dedicated handwash basin requirement.
- Ignoring the waste transfer note and duty-of-care duty.
- Allowing external bins immediately outside a food room door.
- Missing glass and sharps as separate waste streams.
