- 2. Why do we need to understand the risks? • In 2008/09 there were 35 fatalities, 4654 major injuries and a further 7065 injuries that caused the injured person to be off work for over 3 days or more, due to a fall from height (Source HSE) • In the blink of an eye we can hit the ground hard. • Consequences of ignoring fall protection is obvious • Falls from height remain the most common cause of workplace fatality.
- 3. What is working at height? Work at height means work in any place where, if precautions were not taken, a person could fall down and injure themselves. If you do any of the following then you will be working at height, because you can fall from one level to another. • Work above ground level. • Could fall from an edge, through an opening or fragile surface. • Could fall from ground level into an opening in a floor or hole in the ground.
- 4. • Using working platforms such as scaffolds, tower. • Scaffolds, cherry pickers, scissor lifts and podium steps. • Work on a roof, piece of plant or equipment. • Using ladders or stepladders. Examples of working at height
- 5. What precautions do you need to take? • Remember, work at height may be a one off, or routine. • You need more than a head for heights! • We need to protect ourselves and others (including the public from). • You will need to make sure you identify all tasks, which require work at height, so you can make sure they are carried out safely. • The key to preventing injury from work at height is to carry out a risk assessment, so you can choose the right precautions. • This is a simple process, answering the questions on the following slides will help you do this.
- 6. Can you avoid the need to work at height in the first place? • Long-handled tools or other equipment can sometimes be used to safely carry out a task from ground level, e.g. a longhandled brush or roller for painting and water-fed poles with brushes for window cleaning. • Think about whether it is possible to design out the need to work at height, e.g. could new or replacement services, such as pipes or cables, be put at ground level? • If you can’t avoid the need to work at height, you must try to make sure the risk of a fall is prevented.
- 7. Can you prevent a fall? • You can do this by: • Using an existing place of work. • This is a place that is already safe, e.g. a roof with permanent guard rails or a parapet around the edges. • Use a piece of plant or equipment that has fixed, permanent guard rails around it.
- 8. Using work equipment • If you cannot use an existing place of work, consider whether you can use work equipment to prevent people falling. • Tower scaffolds, podium steps, cherry pickers and scissor lifts are some common examples of work equipment, which will do this because the working platforms have guard rails. • If regular access is required, it may be reasonable to create a safe place of work by installing permanent guard rails to and around the work area. • If you cannot put measures in place to prevent a fall, you must try to limit the risk by minimising the distance and/or consequences of a fall.
- 9. Can you minimise the consequences of a fall? • You must first try to avoid and then prevent a fall before using measures that will only minimise or limit the consequences. • Airbags and safety nets are examples of such measures, because they should minimise the risk of injury if someone falls. • Fall arrest equipment will also minimise injury if someone falls, providing the equipment is set up correctly, users know how to look after it and they understand its limitations. • REMEMBER Equipment being used at height may fall, safety nets or drop protection should be used to avoid exposing others to harm – should this happen. • While helmets, gloves and footwear are extremely important personal protective equipment in fall prevention and safety, complete fall protection must include at least one of the following components: Guard Rails, Safety Nets or Personal Fall Arrest Systems.
- 10. What else? • Installing guard rails is an extremely effective fall prevention system. When installing a guard rail it can be temporary or permanent but the following must be adhered to – rails must be able to support 200lbs, stand 39-45 inches high, include a mid-rail, and be inspected in regularly scheduled intervals. • Sometimes guard rails cannot be installed and when this is the case, safety-nets and debris-nets are common. – Safety nets can be designed to catch falling workers – Debris nets can be designed to catch falling tools. – They should be inspected at least every week and after a human or tool falls. – Tools and other debris should be removed immediately from nets. • Sometimes, guard rails and nets are not enough and the serious danger of falling still occurs. In these cases a “personal fall arrest system” should be used. They are comprised of a full body harness, a connecting device and an anchor point. • Body harnesses distribute weight evenly over the shoulders, buttocks and thighs.
- 11. What other additional measures do you need to take to reduce the risk of a fall? When using any equipment for work at height, you also need to make sure: • The people using it are trained to use it safely. • It is regularly inspected and well maintained. • The work is supervised to check people are working safely. • The normal use of ladders or step ladders does not provide measures which either prevent falls or minimise the consequences. So you must be able to show that it was not reasonable to select alternative equipment because the task is low risk and short duration.
- 12. Have you identified whether there are any Fragile surfaces? • You need to be particularly aware of fragile materials when working at height as their presence in, or near the working area, increases the risk. A fragile surface is one, which would be liable to break if a person worked on it or fell onto it. • Common examples include, fibre and asbestos cement roof sheets and many skylights, but could also include bridged materials in silos. • You should make sure you: • Avoid the need to work on or near or pass across them by, e.g. repairing a skylight from underneath using a tower scaffold or from above using a cherry picker; • Prevent a fall by using fixed walkways with guard rails to get across a fragile asbestos cement roof or use suitable working platforms with guard rails during work on or near a fragile surface; • Minimise the consequences of a fall by using nets, airbags or fall arrest.
- 13. What did we learn? • When working off the ground in any capacity you need the right mindset. • Always think about safety and the safest way to accomplish the task at hand. • Never work above the ground if you are overly tired. • Even working under emotional stress should be avoided. • You need your reflexes and mind to be at 100% when working above the ground. • We have mandated training for anyone who works off the ground. • Personal protective equipment is a big part of fall prevention and knowing when and how to use the equipment is critical.
