1. WORKING AT HEIGHTS TRAINING

2. Opening & Background TRAINING RULE Phone on silent mode (if there is an urgent call take it outside ) If you need a break or explanation don’t hesitate to stop us Try to stay always focus on your safety and the safety of your buddy .

3. dbfd TRAINING GOALS I – Identify hazards of working at heights II – Learn about fall prevention and personal fall arrest system III – Know the dangers associated with suspension trauma IV – Learn the work at height requirements followed on the project

4. WORKING AT HEIGHTS TRAINING We therefore, request that you make yourself familiar with this guide and apply the principles and rules when you have to conduct a working at heights activities.

5. WORKING AT HEIGHT Working at height has always been a hazardous business. Work at height is a work in any place, including a place at above or below ground level, where a person could be injured if they fell from that place. Access and egress to a place of work can also be work at height.

6. WORKING AT HEIGHT Fall from heights are the most common cause of serious injuries and death in the construction industry. Before commencing work at height, the potential fall hazards in the workplace must be identified . Once identified the fall hazards have to be controlled

7. To improve upon the past… ….we must care about the future!

8. BUT REMEMBER A FALL FROM ANY HEIGHTS CAN KILL YOU!!!

9. Be trained and found competent in the correct use of fall protection equipment.

10. Several hazards may arise in working at heights, they are but not limited to: Fall from different levels Dropped object Collapse structure / working platform Suspension trauma Dizziness, fatigue / psycho-physical stress TYPICAL HAZARDS

11. FALL FROM DIFFERENT LEVELS

12. DROPPED OBJECT

13. COLLAPSE STRUCTURE / WORKING PLATFORM

14. SUSPENSION TRAUMA Prolong Effects of Suspension Trauma

15. DIZZINESS, FATIGUE / PSYCHO-PHYSICAL STRESS

16. IMPROPER ACCESS

17. DROPPED OBJECT PREVENTION Don’t leave tools or materials lying around Don’t throw items over the edge Toeboards was provided Barricades must be installed Falling object signages must be properly installed

18. DROPPED OBJECT PREVENTION Hand tools must be secured with tool lanyard Chin straps are mandatory while working at height Use the toolbags to hold your tools and keep objects from falling

19. FALL PREVENTION Sides and edges must be properly secured Top Rail Mid- Rail Toe-board

20. FALL PREVENTION Permit is required when removing of grating Opening must be secured with hard barricade with installed signage

21. WHY SCAFFOLD? The primary reason for erecting a scaffold is to provide a safe place of work with safe access suitable for the work being done. All scaffolding shall be erected by competent personnel. All scaffolding must be inspected weekly by a competent inspector and an updated green scafftag shall be put in place .

22. SCAFFOLD

23. SAFE WORKING AT HEIGHT Only trained and medically fit personnel to perform work at height Perform the task at ground level if possible Used fall restraint systems rather than fall arrest systems Risk assessment , PTW and Total Safety Task Instruction Set up barricades and warning signs Ensure effective supervision at all times Ensure housekeeping ( i.e risk of drop objects)

24. PERSONAL FALL PROTECTION What is fall protection? Fall Arrest System Fall Restrain System

25. FALL RESTRAINT vs FALL ARREST SYSTEM Fall Restraint System Prevent you from falling They use a body holding device connected to a reliable anchor, preventing you from reaching zones where the risk of fall exists. Compared to a f all arrest system, fall restraint does not required a rescue plan.

26. FALL RESTRAINT vs FALL ARREST SYSTEM Fall Arrest System Protect you after you fall; They stop the fall before you hit the surface. These system use a body holding device connected to a reliable anchor; They arrest and restrict a fall preventing you from colliding with the ground or structure; You are required to have a rescue plan in place.

27. PERSONAL FALL PROTECTION Anyone accessing an elevation equal or above 2 meters must be wearing a full body harness When near the edge (protected or not) 100% hook-up is required Full body harness + Two lanyards (used according to manufacturers recommendation)

28. LANYARDS Example of Twin Tail Lanyard Single absorber with twin lanyards Example of Double Lanyard Single absorber with twin lanyards Understanding how to clip these lanyard properly is a potentially life critical decision for the wearer. Note: Proper use of these lanyards requires training beyond the content of this slide.

29. IMPROPER USE OF TWIN TAIL LANYARD Never back hook the spare lanyard onto your self IT CAN BE FATAL  

30. CORRECT USE OF TWIN TAIL LANYARD ….instead of back hooking the spare lanyard to yourself…… Connect the spare lanyard directly to the other anchor point, or Connect both hooks to the same anchor point.

31. FULL BODY HARNESS The lanyard must be kept up in front. The loose lanyard creates entanglement risk. Do not walk and drag the line and hook behind you on the floor, you might damage it.

32. SHOCK ABSORBER In a free fall they help by absorbing or lessening the impact, having the power of reducing trauma suffered to the body. Connect the shock absorber to D-Ring located on upper back between the shoulder. Make sure that the self locking hook is secured.

33. ANCHORAGE SELECTION Select an anchor point with strong enough to withstand the impact / forces involved in arresting a fall Where there is the potential for a fall, the anchor point must comply with the three following factors: Minimum breaking force of about 15kN (approx. 1500kg) As high as possible, above the harness rear ‘D’ ring. Anchor points are to be as centrally located as possible, no more than 15 degrees vertically from your position.

34. ANCHORAGE SELECTION

35. ANCHORAGE SELECTION

36. CORRECT ANCHORING POINT Directly above D-ring to avoid swinging At least shoulder height and overhead if possible – reduces fall distance. Life lines must be installed, inspected and certified by competent personnel before use Scaffold tubes Life line

37. INADEQUATE ANCHORING POINTS

38. INSPECTION OF FULL BODY HARNESS Inspect before each use Inspect assembly for sever wear, cuts , burns, frayed edges, abrasion, UV damage , failed stitching or metal fittings damage If harness is used in fall, get a new one Damage harness and lanyard must be replace with new one

39. SUSPENSION TRAUMA Suspension Trauma is a potential hazard for all people working at heights in a harness It can result in unconsciousness, followed by death in less than 30 minutes (could been even within 10-15) Avoid suspension trauma by alternatively raising one leg and then the other to assist with improving the blood circulation from the lower limbs. The JOB HAZARD ANALYSIS MUST include a rescue plan IF a person falls. Ensure rescue equipment is immediately available and that rescue methods are practiced regularly

40. RESCUE Emergency services to be contacted immediately Must come rapidly to minimize the dangers of suspension trauma If possible and conscious, self rescue is most desirable Time is of the essence

41. RESCUE Rescue plan is mandatory in the JHA Training on the Height Rescue Training on suspension trauma

42. EXAMPLE OF RESCUE EQUIPMENT Mobile elevated platform or crane with man basket

43. Any Question?

44. NO JOB IS SO URGENT THAT WE CANNOT TAKE THE TIME TO DO IT SAFELY.
