ABC of Safety in the Biological Sciences




None known.
Keep away from heat, sparks or a naked flame.
Use with adequate ventilation.
Avoid contact with eyes, skin and clothing.
Avoid inhalation of the vapour.
Combustible, colourless liquid.
Combustible liquid ­ do not handle close to heat or a naked flame. An eye and skin irritant and the fumes can be harmful if inhaled. Mildly toxic if ingested.
Skin ­ remove contaminated clothing and shoes and immediately wash the affected area with large amounts of water until all evidence of the chemical has been removed (approximately 15 minutes). If irritation persists seek medical advice. Wash contaminated clothing before re­use.
Eyes ­ immediately wash the affected eye with large amounts of water until all evidence of the chemical has been removed (approximately 15 minutes). Seek medical advice.
Inhalation ­ remove from the patient to fresh air, rest and keep warm. Seek immediate medical advice.
Ingestion ­ give two to four glasses of water to drink and seek immediate medical advice.
Methyl trisulphide is incompatible with oxidising agents. Heating produces toxic fumes of sulphur and carbon.
Store in a cool, dry atmosphere away from heat or naked flames. Store away from oxidising agents.
Although toxicity levels have not been established this substance is known to be harmful if inhaled. Therefore use a fume hood and wear protective clothing. A long sleeved laboratory coat or gown, rubber gloves, safety goggles and a face mask as a minimum standard. If exposure is likely to be excessive wear a respirator or self­contained breathing apparatus.
Remove all sources of ignition. Absorb the material in vermiculite or other suitable absorbent and place into an impervious container. Package appropriately for safe feeding into an incinerator or dissolve in a compatible solvent prior to incineration. Use an incinerator equipped with an after­burner and scrubber or contact with a licensed waste disposal operator for removal. Discharge, treatment or disposal may be subject to particular local by­laws and regulations.
