The correct answer is: Insisting that machines are switched off when not in use. This limits the risk of accidents caused by the machines to those who don't use them and should not be costly.

Not all the staff who work on the premises will be subject to health and safety risks that can be limited by protective clothing (office and security staff for example), so insisting that they wear protective clothing is unnecessary. The 15 minute safety talk should be a useful (though limited) introduction to health and safety procedures, but will need to be followed up with further training and information. Recording accidents is part of risk reporting rather than risk management.
