Nebosh Igc Questions and Answers 1998-2005 free essay sample
Most candidates coped reasonably well with part (ii) by describing circumstances such as insecure and unstable loads, manoeuvring with the load elevated, colliding with kerbs and other obstructions, cornering at speed, braking harshly, driving on uneven or soft ground, and mechanical failure.
