Occupational safety and health
Occupational Safety and Health is a set of laws that have been made to protect the health and the safety of people when they are working.  Health and safety rules will vary a lot from one country to another.  Some countries have very strict rules.  Rules about Health and Safety have been made since 1950 when the International Labour Organization (ILO) and the World Health Organization (WHO) agreed about standards of health in the workplace.
