The use of chemical cleaning agents to improve the flow through the drain from a sink and remove stains from the sink itself; many use strong acids or alkalis, others contain enzymes or hypochlorite.

This guide covers the handling of chemical spills in D&T, food and art. The majority of chemicals used in these areas, are considered hazardous but, because they are used in small quantities only, do not represent the same level of risks as chemicals in science.

This guide identifies the areas that should be considered prior to embarking on practical work in a general teaching room, rather than a workshop, food room or art studio.

This is a set of diagrams and other information to support those carrying out audits in D&T or Art and Design.
