2 WHAT IS A CHEMICAL RISK ASSESSMENT?? A RISK ASSESSMENT IS SIMPLY A CAREFUL EXAMINATION OF WHAT, IN YOUR WORK, COULD CAUSE HARM TO PEOPLE, SO THAT YOU CAN WEIGHT UP WHETHER YOU HAVE TAKEN ENOUGH PRECAUTIONS OR SHOULD DO MORE TO PREVENT HARM (HSE) CHEMICAL RISK ASSESSMENT IS AN ASSESSMENT OF THE RISK FROM CHEMICALS IN THE WORKPLACE TO THE HEALTH AND SAFETY OF PERSONS AND THE AIM IS TO IDENTIFY CONTROL MEASURES WHICH WILL REDUCE THE RISK TO AS LOW A LEVEL AS POSSIBLE RESULT: WRITTEN DOCUMENT WHICH DETAILS THE HAZARDS EXPOSURE LIMITS, CONTROL MEASURES FOR EACH PROCEDURE WHICH INVOLVES THE STORAGE, USE OF TRANSPORT OF HAZARDOUS SUBSTANCES/CHEMICAL AGENTS

3 CHEMICAL RISK ASSESSMENTS- WHAT TO DO??? 1: CHECK CHEMICAL INVENTORY IN THE LAB 2: IF CHEMICAL IS NOT ON INVENTORY, PLEASE PUT IT ON 3: PLEASE DOWNLOAD MSDS SHEET FOR CHEMICAL 4: CHECK MSDS SHEET TO SEE IF CHEMICAL IS HAZARDOUS 5: IF CHEMICAL IS HAZARDOUS, A CHEMICAL RISK ASSESSMENT MUST BE DONE

R46 May cause heritable genetic damage. R60 May impair fertility. R61 May cause harm to the unborn child. R21 Also harmful in contact with skin. R25 Also toxic if swallowed. R26 Also very toxic by inhalation. R48/23 Also toxic: danger of serious damage to health by prolonged exposure through inhalation. R 8 Contact with combustible material may cause fire. R34 Causes burns. R42/43 May cause sensitization by inhalation and skin contact. R50/53 Very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. High Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Avoid contact with skin and eyes. Avoid formation of dust and aerosols.Avoid exposure - obtain special. instructions before use. Provide appropriate exhaust ventilation at places where dust is formed.Keep away from sources of ignition. - No smoking.Keep away from heat and sources of ignition.Normal measures for preventive fire protection Product Burn in a chemical incinerator equipped with an afterburner and scrubber but exert extra care in igniting as this material is highly flammable. Offer surplus and non-recyclable solutions to a licensed disposal. company. Contact a licensed professional waste disposal service to dispose of this material. Contaminated packaging Dispose of as unused product. Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide. Special hazards arising from the substance or mixture Potassium oxides, Chromium oxides Wear self contained breathing apparatus for fire fighting if necessary. Use water spray to cool unopened containers. FIRST AID MEASURES aid measures General advice Consult a physician. Show this safety data sheet to the doctor in attendance. If inhaled If breathed in, move person into fresh air. If not breathing, give artificial respiration. Consult a physician. In case of skin contact. Take off contaminated clothing and shoes immediately. Wash off with soap and plenty of water. Take victim immediately to hospital. Consult a physician. In case of eye contact Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician. If swallowed Do NOT induce vomiting. Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician. 4.2 Most important symptoms and effects, both acute and delayed Ulceration, Material is extremely destructive to tissue of the mucous membranes and upper respiratorytract, eyes, and skin.
