Examiner Tips

Expert advice for maximising your marks

💡When explaining procedures, structure your response in chronological order: pre-fumigation, fumigation, post-fumigation.
💡For documentation tasks, ensure all forms are correctly filled with dates, times, signatures, and any anomaly noted.
💡In practical assessments, verbalize your actions to demonstrate understanding of safety protocols.

Common Mistakes

Pitfalls to avoid in your exam answers

Underestimating the required dosage due to miscalculation of grain volume or ignoring temperature effects.
Failing to properly seal sheet edges, leading to gas leakage and reduced efficacy.
Neglecting to monitor phosphine concentration levels during exposure period, risking under-dosing or overexposure.
