Acetic Acid – to adjust pH Ethylene Glycol – Constituant for running buffer Bromophenol blue – colour marker to determine location of saccahrides Phenol red – colour marker to determine location of saccharides 6 RISKS to HEALTH and SAFETY from INTENDED USE From personal exposure or hazardous reactions. Refer to OELs, flash points, etc., as appropriate. Are pregnant women, breast-feeding mothers especially at risk? Acrylamide/bis-Acrylanmide – Risk of harm due to splashes of liquid reagent to unprotected eyes and skin. Small risk of inhalation. User may become sensitised with use. Ammonium persulfate – Small risk of harm by inhalation. Risk of harm due to splashes to the unprotected skin and eyes. User may become sensitised with use. Temed – Corrosive – causes burns. Small risk of harm from inhalation. Risk of harm from splashes to unprotected skin and eyes Flammable – vapour may trail towards sources of ignition. Ethylene Glycol – Small risk of inhalation. Risk of harm from splashes to skin and eyes. Acetic Acid – Corrosive risk by inhalation. Risk of burns due to splashes to unprotected skin and eyes. Flammable – refrain from use by ignition sources. Phenol red – Small risk of irritation by inhalation. Risk of harm due to splashes to unprotected skin and eyes. 7 CONCLUSIONS ABOUT RISKS Is level of risk acceptable? Can risk be prevented or reduced by change of substance/procedure? Are control measures necessary? Due to the nature of some of the chemicals listed in this assessment there is a small risk . But due to the small amounts used and as long as measures laid out in section 8 are followed then the level of risk is acceptable. Non of the chemicals used can be replaced with other “ less hazardous” reagents. 8 CONTROL MEASURES Additional to Good Chemical Practice Laminar flow hood recommended for manipulation of acrylamide powders. Wear labcoat, safety glasses and chemical resistant gloves. Be aware of and avoid sources of ignition. 9 INSTRUCTION/TRAINING Specify course(s) and/or special arrangements. One to one initial instruction 10 MONITORING Performance of control measures, Users of Respiratory sensitisers need to be registered with the HSU and Occupational Health PRIOR to commencement of work, to enable assessment, monitoring of exposure and possible subsequent sensitisation. Instruction given as to importance and application of control measures. Training given to aid recognition of initial symptoms of sensitisation. Personal exposure Health Surveillance Exposure to sensitisers - Lung function tests and health review as instructed by Occupational Health. Records kept of outcome courtesy of Occupational Health. Exposure to sensitisers - Lung function tests and health review as instructed by Occupational Health. Records kept of outcome courtesy of Occupational Health. 11 WASTE DISPOSAL PROCEDURE See School Server for Approved Procedure Document on specific Chemical Waste Disposal. Unused acrylamide solutions should be polymerised with APS and TEMED prior to disposal by incineration. Used polymerised acrylamide gels should be disposed of by incineration. Other reagents, ammounts listed within the protocol can be disposed of down the sink with copious amounts of water. 12 REVIEW Enter the date or circumstances for review of assessment (maximum review interval 5 years) 19/06/07 13 EMERGENCY ACTION TO CONTROL HAZARDS To stabilize situation eg spread absorbant on liquid spill; eliminate sources of ignition, etc. Small amounts of reagents listed within this protocol can be mopped up with absorbant material ( tissue ) . Large spills of Acrylamide should be treated/mopped up with an adsorbant material, TO PROTECT PERSONNEL Evacuation, protection for personnel involved in clean-up, Special First Aid Personal contact with listed reagents should be treated immediately by flushing with copious amounts of water before seeking medical advice. Respiratory difficulty should be treated immediately by moving to area of well ventilated clean air and seeking medical advice if deemed necessary due to unresolvement of symptoms. Contaminated clothing should be immediately removed. Clean-up/decontamination TO RENDER SITE OF EMERGENCY SAFE Areas of spillage should be cleaned with a diltue decon solution Acrylamide : Large spills warrant evacuation. Use of self-contained breathing apparatus, rubber boots and heavy duty chemical resistant rubber gloves. Spill should be mopped up with absorbant material, swept up into a bag, held for specialist waste disposal by Departmental Stores. Ventilate area and wash spill with diltue decon solution after material pick up is complete. Small spllls od acrylamide should be mopped up immediately, placed in a bag for specialist waste disposal. Area cleaned with diulute decon solution. CONTACT Dr.J.E.Turnbull PHONE 47527 10.10.00 * ** *** Prefix T is used for Teaching Assessment Number. Please include amount of chemicals used and how.
