Helium, an odourless and colourless gas, is a substance utilised for varying applications; from weather balloons and welding gases, to a carrier gas in industrial operations. Helium tends to rise away from the working area due to its low density. As a liquid, helium can be utilised as a closed system cooling agent. Helium, as a balloon gas, is stored in high pressure cylinders, therefore consideration needs to be given to safe storage and the way it is handled, so as to avoid accidents and personal harm.
When helium comes into contact with the skin, individuals again should immerse the relevant area of the body with warm water and seek medical attention.
When helium is inhaled, knowingly or unknowingly, it displaces the air.
Can cause dizziness, nausea, light-headedness and/or a temporary loss of consciousness.
