ABC of Safety in the Biological Sciences




Avoid skin and eye contact.
Avoid inhalation.
Avoid ingestion.
Keep away from heat or naked flames.
Keep the container tightly sealed.
Store in the dark.
Wash hands thoroughly after handling.
White crystalline powder.
This substance is a skin and eye irritant which may cause sensitisation of the skin. It is toxic if inhaled or ingested.
Skin ­ immediately wash the affected area with soap or mild detergent and large amounts of water until all evidence of the chemical has been removed (approximately 15 minutes). If irritation persists or an allergic reaction begins seek medical attention.
Eyes ­ immediately wash the affected eye with large amounts of water until all evidence of the chemical has been removed (approximately 15 minutes). If irritation persists seek medical attention.
Inhalation ­ remove from the area of exposure to fresh air. If respiration has ceased apply artificial respiration. Keep warm and allow to rest. If respiratory distress persists seek medical advice.
Ingestion ­ wash the mouth with water then give water to drink. Seek immediate medical attention.
Heating produces toxic fumes of sulphur and nitrogen compounds. Discolours in the Presence of light or air.
Store in the dark, in a tightly sealed container, in a cool, dry atmosphere away from heat.
Wear protective clothing to avoid skin or eye contact, inhalation or ingestion. A long sleeved laboratory coat or gown, rubber gloves, safety goggles and a face mask as a minimum standard.
Rubber gloves, face shield and laboratory coat. Have an all purpose canister respirator available.
A gas leak: keep the concentration of the gas below the explosive mixture range by forced ventilation. Remove the tank to an open area and allow dissipation to the atmosphere. Attempt to cap the valve outlet and return the tank to the supplier.
A liquid: absorb on paper. Evaporate in an iron pan in a flame proof fume hood then burn the paper.
A solid: sweep on to paper and place in an iron pan in a fume hood. Burn the paper and compound.
A gas leak: pipe the gas into an incinerator or lower into a pit and allow to burn.
A liquid: atomise into an incinerator. Combustion may be improved by mixing with a more flammable solvent.
A solid: make up packages in paper or other flammable material. Burn in the incinerator. Or the solid may be dissolved in a flammable solvent and sprayed into a fire chamber.
