2WHAT 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 POSSIBLERESULT: 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
3CHEMICAL RISK ASSESSMENTS-WHAT TO DO??? 1: CHECK CHEMICAL INVENTORY IN THE LAB2: IF CHEMICAL IS NOT ON INVENTORY, PLEASE PUT IT ON3: PLEASE DOWNLOAD MSDS SHEET FOR CHEMICAL4: CHECK MSDS SHEET TO SEE IF CHEMICAL IS HAZARDOUS5: IF CHEMICAL IS HAZARDOUS, A CHEMICAL RISK ASSESSMENT MUST BE DONE

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. Takevictim immediately to hospital. Consult a physician.In case of eye contactRinse thoroughly with plenty of water for at least 15 minutes and consult a physician.If swallowedDo NOT induce vomiting. Never give anything by mouth to an unconscious person. Rinse mouth withwater. 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 andupper respiratorytract, eyes, and skin.
