This UK-focused course covers the prescribed general training elements: chemistry and products; labels and safety data sheets; health effects and sensitisation; exposure factors; prevention and engineering controls; hygiene; PPE/RPE use and limitations; leaks, first aid, waste, supervision and renewal records.
Course structure: seven lessons followed by a separate course-level 12-question final assessment. The pass mark is 80% and retakes are allowed.
