Hazard Alert: Working Safely with Scissor Lifts

1 Working Safely with Scissor Lifts Scissor Lifts provide a safe and reliable platform for workers to perform job tasks when used according to the manufacturer's instructions. When not used properly, Scissor Lifts can present a serious Hazard to workers. employers are responsible for keeping workers safe. This Hazard Alert highlights specific hazards present in workplaces where Scissor Lifts are used and controls employers must implement to prevent injuries or fatalities. Mid Rail Introduction Scissor Lifts , and Top Rail Scissor Lifts are work platforms used to Safely employers should move workers vertically and to different locations make sure that Work Platform in a variety of industries including construction, those workers show retail, entertainment and manufacturing.

2 Scissor that they can use a Lifts are different from aerial Lifts because the lifting Scissor lift properly. mechanism moves the work platform straight up and Safe Scissor lift use down using crossed beams functioning in a Scissor - includes properly like fashion. Although Scissor Lifts present hazards maintaining the similar to scaffolding when extended and stationary, equipment, following using Scissor Lifts Safely depends on considering the manufacturer's equipment capabilities, limitations and safe practices. instructions, providing workers Over a one-year period, OSHA investigated ten training and needed preventable fatalities and more than 20 preventable personal protective injuries resulting from a variety of incidents involving equipment (PPE), and Scissor Lifts .

3 OSHA's investigations found that most implementing safe injuries and fatalities involving Scissor Lifts were the work practices. An example of a Scissor lift. result of employers not addressing: Fall Protection Stabilization Positioning Fall Protection Scissor Lifts must have guardrails installed to prevent How to Safely Use Scissor Lifts workers from falling (see 29 CFR (g) or 29. employers need to assess the worksite to identify all CFR (a)(3)(vii)). possible hazards in order to select the appropriate employers should train workers to: equipment for the task.

4 employers who use Scissor Check to see that a guardrail system is in place Lifts need to evaluate and before Working on the Scissor lift. implement effective controls Only stand on the work platform; never stand on that address fall protection, the guardrails. stabilization and positioning. Keep work within easy reach to avoid leaning away Only trained workers from the Scissor lift. should be allowed to use 1-800-321-OSHA (6742) 1. Stabilization employers should ensure that Scissor Lifts are stable Caution: Wind Can Make Extended and will not tip over or collapse.

5 Some safe work Scissor Lifts Unstable practices to ensure safe, stable conditions for Scissor lift use include: During the Fall 2010 college football season, a student who was also an employee of the Follow the manufacturer's instructions for safe University of Notre Dame was killed while movement this usually rules out moving the lift in filming the school's football team practice from an elevated position. a Scissor lift. Reportedly, the untrained worker Isolate the Scissor lift or implement traffic control raised the lift over 39 feet to film the practice.

6 Measures to ensure that other equipment cannot The wind gusts that day were more than 50. contact the Scissor lift. miles per hour. The high winds blew the lift Select work locations with firm, level surfaces away over, killing the worker. from hazards that can cause instability ( , drop- offs, holes, slopes, bumps, ground obstructions, or debris). Positioning Use the Scissor lift outside only when weather Positioning the Scissor lift to avoid crushing or conditions are good. Scissor Lifts rated for outdoor electrocution hazards is important for safe use.

7 Use are generally limited to wind speeds below 28. miles per hour. Crushing hazards are present in workplaces using Scissor Lifts and may expose workers nearby, even those not Working on the Scissor lift. Scissor Lifts present crushing hazards similar to vehicles and other mobile equipment at worksites. employers should train workers to be watchful when: A moving Scissor lift is near a fixed object. A moving vehicle and the Scissor lift are operating Although rare, the collapse of Scissor Lifts can be closely. prevented if employers : The Scissor lift passes under a fixed object, Ensure that safety systems designed to stop such as a door frame or collapsing are maintained and not bypassed.

8 A support beam. Never allow the weight on the work platform to exceed the manufacturer's load rating. Positioning the Scissor lift to Never allow equipment avoid electrocution, arc flash, other than the Scissor and thermal burns is important mechanism to be used to for Safely using Scissor Lifts raise the work platform near energized power lines. ( , using a forklift to lift Since electricity can arc or the work platform). jump from the power line Keep the lift from being to the Scissor lift or worker, struck by other moving electrocution can occur even if neither the Scissor lift equipment on the nor the worker touches the power line.

9 Worksite. employers should use the following work practices to ensure that Scissor Lifts are Safely positioned: 1-800-321-OSHA (6742) 2. Implement traffic control measures around the General Industry Scissor lift to prevent other workers or vehicles from Guarding Floor and Wall Openings getting too close. and Holes Use ground guides when operating or moving the Safety Requirements for Scaffolding Scissor lift around the workplace. Manually Propelled Mobile Ladder Select work locations that do not approach Stands and Scaffolds (Towers). electrical power sources ( , power lines, Selection and Use of Work Practices transformers) by at least 10 feet and that do not pose other overhead hazards ( , other utilities, Shipyards branches, overhangs, etc.)

10 Scaffolds or Staging If the job task requires work near an electrical source, ensure that the worker is qualified and has Construction received the required electrical training. (29 CFR Safety Training and Education ; 29 CFR ; 29 CFR 1926 General Requirements Subpart V). Additional Requirements to Specific Types of Scaffolds Maintaining Scissor Lifts Training Requirements employers must regularly maintain Scissor Lifts to ensure that they are safe to use ( , prevent the Additional Information lifting mechanism from collapsing).
