- Neglecting to clean weighing surfaces between different products, risking cross-contamination and inaccurate tare weights
- Not documenting results immediately or in the prescribed format, resulting in missing or illegible records
- Ignoring minor deviations as insignificant rather than investigating and correcting root causes
- Failing to verify scale calibration or ignoring drift, leading to inaccurate measurements and potential non-compliance.
- Mistaking tare weight for net weight, resulting in incorrect product weight declarations and packaging errors.
- Not allowing sufficient time for the scale to stabilize before recording, causing inconsistent readings.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A batch of apples is received at a packing facility. The batch weighs 500 kg. After sorting, 350 kg are Class I, 100 kg are Class II, and the rest is rejected. Calculate the percentage of rejected apples and explain the likely reasons for rejection.
- 1.Step 1: Identify the total weight and the weights of each class. Total = 500 kg, Class I = 350 kg, Class II = 100 kg.
- 2.Step 2: Calculate the rejected weight: 500 - 350 - 100 = 50 kg.
- 3.Step 3: Calculate the percentage rejected: (50 / 500) × 100 = 10%.
- 4.Step 4: Explain reasons: Rejected apples may have severe blemishes, rot, pest damage, or fail to meet minimum size or quality standards.
Question: Describe the correct procedure for taking a temperature reading of a pallet of leafy greens in a cold store. (6 marks)
- 1.Step 1: Calibrate the temperature probe before use (e.g., using iced water or a certified thermometer).
- 2.Step 2: Insert the probe into the centre of the pallet, between leaves, to get the core temperature, not just the surface.
- 3.Step 3: Wait for the reading to stabilise (usually 30 seconds to 1 minute).
- 4.Step 4: Record the temperature and the time, and compare it to the required storage temperature (1-4°C).
- 5.Step 5: If the temperature is out of range, report it to a supervisor and take corrective action, such as adjusting the store thermostat or moving the pallet.
