6. RISK 6  RISK is the likelihood and severity of a hazard affecting people, the environment, premises and equipment

7. HAZARD and RISK  Risk assessment requires you to know hazard & risk  HAZARD is something with the potential to cause harm  RISK is the likelihood that harm with occur  RISK = HAZARD x EXPOSURE 7

8. THE NEED TO ASSESS HAZARD AND RISK  Potassium dichromate and flour examples in notes  Can a high hazard substance like potassium dichromate pose a low risk?  Can a low hazard substance like flour pose a high risk? 8

19. ORGANISATIONAL 19 https://psychosocialhazard.files.wordpress.com/2011/04/ist2_1935044_angry_boss_employee1.jpg?w=604 Anything in the workplace that may cause harm by putting people under stress

20. How many hazards can you find? 20

21. HAZARDS IN THE LAB  Look around and identify any hazards in the lab 21

22. RISK CONTROL  Aim – to minimise risk by:  Removing known hazards  Avoiding known hazard  Putting in place workplace precautions E.g. guard around moving machinery parts, respirator, gloves etc. 22

23. 5 STEPS TO RISK ASSESSMENT 1. LOOK AT HAZARDS 2. DECIDE WHO MAY BE HARMED AND HOW 3. EVALUATE RISKS - are existing precautions adequate? 4. RECORD YOUR FINDINGS 5. REVIEW from time to time & revise if necessary 23

24. HIERARCHY OF CONTROL 1. Remove the hazard  Choose a safer alternative if possible  If not, change process, change hazardous chemical, use safer form of chemical etc. 2. Minimise exposure to hazard  e.g. use fume hood, enclose system/equipment, reduce number of people exposed/time of exposure 3. Provide training 4. Use PPE if hazard cannot be removed  This should be a last resort, chosen appropriately and maintained/serviced 5. Use safety signs if hazard cannot be removed 24

25. PPE 25

26. RISK ASSESSMENT  Must be done by law  Does not have to be perfect but be ‘suitable and sufficient’.  Employers must be able to show Proper checks for hazard were made  People who may be harmed identified  Significant hazards dealt with  Reasonable precautions put in place  Remaining risk low  Employees involved in the process 26

27.  The law says employers must do all that is ‘reasonably practicable’ to make the workplace safe. 27

28. 28 Case Study 2 In your groups identify steps in making a risk assessment
