ABC of Safety in the Biological Sciences
SPRAYS
Most of the sprays used in laboratories contain a propellant which is highly flammable. Sprays should not be used near naked flames or stored at temperatures of above 50°C or below 6°C.
Some cans contain Freon as propellant although the use of chlorofluorocarbons is declining for environmental reasons. Contact with the skin may cause severe low temperature burns (ie. frost bite). Inhalation can cause severe respiratory problems. If discomfort develops and persists seek immediate medical advice.
