Technical reference
Maintenance is a prerequisite programme. It lets other controls work: a cool room can't hold food at temperature if its seal has failed, and a cleaning schedule can't clean a surface that is flaking. It also brings its own physical and chemical when work is done in a food area.
Refrigeration failures are often gradual. A worn seal or a dirty condenser may raise a unit's temperature slowly enough that nobody notices, so service schedules and temperature records work together.
Parts left after a repair are a foreign-body , and cooking won't remove them. Screws and swarf are usually found only by counting, inspection or a where one is used.
Parameters
| Hazard | Physical and chemical contamination from premises and work, and loss of temperature control from failed equipment |
|---|---|
| Legal duty (Australia) | Good state of repair and working order, including vehicle parts carrying food ( cl. 21) |
| Everyone on site (Australia) | All practicable measures so people don't contaminate food ( cl. 18) |
| Equipment | Adequate and fit for its intended use (Standard 3.2.3 cl. 12) |
| Visitors and maintenance workers | Briefed, supervised, gowned and asked to report illness ( §12) |
| After repairs | Clean and before use. New Zealand's template plan also asks for pipes to be flushed |
Records that prove it
- Preventive maintenance schedule
- Fault log: found, nature, planned repair, due and closed dates
- Temporary repairs, with a permanent fix date
- Signed contractor and visitor rules
- Handover after work in a food area
- Audit review of the log
CCP or prerequisite?
That depends on the for your process. The number, if it has one, belongs to your plan.
