INTRODUCTION: Here, we shall explain the regulations which are directly or indirectly concerned with laboratory work. These regulations have legal validity. As compared to laboratories in educational institutions, laws about laboratories in industrial unit are more prominent. Factories Act, for example, covers almost all aspects of industrial units. The reason may be that accidents and health hazards are more possible and serious in industrial situations rather than in educational institutions. Still much of legislation regarding design of buildings, electricity, fire and storage of hazardous materials etc. are applicable to both types of situations. The educational institutions should also take particular care to follow Excise Rules (applicable to purchase of alcohol) and regulations regarding experiments on animals. While we explain regulatory aspects regarding health, safety etc. in laboratory situations, we shall indicate their applications to both the types of laboratories.
