The 'six-pack' is the name given to the half-dozen most widely quoted sets of health and safety regulations. They came into effect in Britain after six European directives, collectively known as the 'six-pack', were issued by the European Commission.
The main set of regulations is the Management of Health and Safety at Work Regulations 1999, also known as the 'Management Regs'. They place a legal duty on employers to carry out a risk assessment as a first step in ensuring a safe workplace, and lie at the heart of the modern approach to health and safety at work.
Other 'six-pack' regulations cover heating, lighting and ventilation at work, the safe use of computer screens and keyboards, handling heavy or awkward loads, rest breaks, and personal protective equipment.
