The document discusses different types of safety signs used in engineering environments. Hazard signs warn of potential hazards and have a triangular shape with black border and pictogram. Mandatory signs tell people what safety precautions must be taken and are blue with white text and pictogram. Prohibition signs tell people what must not be done and show a pictogram in a red circle with line through it. Fire signs show the location of fire equipment and are red with white text and pictograms. Safe condition signs point out how to make an area safe or reach safety in an emergency and have a green background with white text and pictograms.

safety precautions they need to take
● Examples include need for eye or
ear protection, need to wash hands,
need to wear hard hat, need to use

● Examples include fire extinguisher,
fire hose, fire blanket, fire alarm
call point.
● They are red with white text and
pictograms.

making safe or getting to safety in the event of
an emergency
● Examples include emergency stop, First Aid
box, fire exit, evacuation point, eye wash
station.
● They have a green background with white
pictograms and text.
