✓ Correct answer: A. Prevent its use until the required information is reviewed and controls are agreed COSHH requires assessment of hazardous substances before use. Without safety data and agreed controls, the product must not be used. Why the other options are incorrect: • Allow use if operatives have used similar products before: Similarity to other products does not remove the need for assessment. • Proceed with additional PPE as a precaution: PPE alone may not adequately control exposure. • Store the product away from other materials and continue work: Storage does not address the risks of use. • Ask the supplier for information after work has started: Controls must be established before exposure occurs.
