This will include any arrangements to deal with accidents, incidents or emergencies, such as those resulting from serious spillages. The assessment must also include the health and safety risks arising from storage, handling or disposal of any of the substances
- prevent, or if this is not reasonably practicable, control exposure to such substances
- provide staff with information, instruction and training about the risks, steps and precautions the employer has taken to control these risks, eg provision of appropriate rubber gloves or appropriate eye protection
