Abstract

Specifies requirements, recommendations and guidelines to promote safety in laboratories where chemicals are handled.

Scope

This Standard sets out requirements and recommended procedures for safe working practices in the chemical laboratory. It includes procedures for handling flammable, toxic, corrosive, unstable and highly reactive chemicals and makes reference to the handling of compressed and liquefied gases. The Standard also includes information on hazards associated with working in the chemical laboratory.
