What are some of the chemicals from the technology area that must be used with caution and what are their associated risks?

0

A full list of hazardous chemicals can be found at the Department’s intranet. Some examples and associated risks are shown here: • Acetylene – forms highly explosive mixtures with air. • Bleach/Bleaching powder – evolves chlorine gas which is highly irritant to the lungs. • Hydrochloric acid – releases hydrogen gas when open to the atmosphere. This gas is highly irritant to the lungs. • Iron filings/powder – hazardous when mixed with sulphur, chlorine or bromine. • Methylated spirits – highly flammable, and burns with nearly colourless flame. • Nitric acid – powerful oxidising agent. Produces severe burns and can explode when mixed with many combustible materials. • Sulphuric acid (concentrated) – reacts violently with water. • Zinc powder – is flammable, and hazardous when mixed with sulphur.
