When using the forge pupils should be aware of
the following Hazards
- Care should be taken when carrying hot metals
(particularly metals at black heat that may not
appear hot) - Clay bricks should not be heated as they can
disintegrate violently. - Ceramic chips remain hot for a considerable time
after the heat source has been removed. - Foreign materials present in the forge can cause
fumes. Stones can explode. - Quenching of hot materials, particularly tubular
components can cause risk of scalding.
