1 School Of Medicine Biomedical Sciences COSHH Risk Assessment Form Before any experimental involving the use of chemicals or reagents is undertaken, potential hazards must be identified and an assessment made of the risks posed by these hazards in the work activity in which they are involved. This risk assessment is a legal requirement to comply with the Control of Substances Hazardous to Health (CoSHH) Act and is the responsibility of the research workers supervising the research projects. Before undertaking experimental s, all members of staff must read and sign the relevant CoSHH assessments Title of Procedure: Labs Involved: Brief Description: Analysis of compounds on LC-MS M147 Solvent extraction of pharmacological compounds and their metabolites from biological samples (urine, plasma, human liver microsomes and recombinant microsomes) and subsequent analysis by LC-MS. See CoSHH form no 174 for making up of solutions used in this. Please note: Known carcinogens, teratogens and mutagens should only be used in consultation with senior staff and the Departmental Safety Officer. All user must have read University supplementary Code of Practice for the use of such substances and comply with its recommendations. It is important to realise that the use of certain carcinogens is banned by law. Chemical/Reagent Hazard Stock Volume/ Quantity Emergency Action Risk level Precautions Disposal Methanol 5-70% Highly flammable, toxic by ingetsion, inhalation and skin. Chronic effect on eyes.

6 Good Laboratory Practice should be adhered at all times Common sense at all times! Never eat, drink or apply cosmetics in the laboratory. Wash your hands in the designated sinks whenever you have finished your lab work. Be familiar with the potential hazards involved in your work and take appropriate precautions. Wear protective clothing as needed, lab coats are a minimum. Keep your work area clean and tidy. Dispose of materials appropriately. Use appropriate care with electrical equipment. Use appropriate care with sharps Use appropriate care with substances of extreme temperatures (liquid nitrogen or hot liquids) Operate maintain and service all your equipment properly, if in doubt ask! Work in appropriate containment hoods where necessary. Precautions to be taken: SOPs for centrifuges, multi-tube vortexers, mass spec, vortex evaporators to be read before commencing. Solvent and Acid winchesters (2.5L) to be carried in winchester carriers when they are being moved between labs EMERGENCY PROCEDURES FIRST AID IF PERSONNEL ARE AFFECTED (fumes, contamination/contact) TREATMENT TO BE ADOPTED EYES Irrigate with eye wash for at least 10 minutes. Obtain medical attention. LUNGS Remove from exposure. Rest and keep warm. In severe cases obtain medical attention. SKIN Drench skin with Remove contaminated clothing. In severe cases seek medical attention. MOUTH Wash mouth out thoroughly and give very small SIPS of Do not induce vomiting. Obtain medical attention.
