Working at Height WELCOME • Introduction • Emergency Exit • Timings : 2:30PM – 3:00 PM • Training Norms • Mobile Phones • Smoking 3/08/2023 2 What Is Work At Height ? Work at height is 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. Examples of work activities that are classified as working at height include : WORKING ON A FLATROOF WORKING FROM A LADDER WORKING AT GROUND LEVEL ADJACENT TO AN OPEN EXCAVATION WORKING NEAR OR ADJACENT TO FRAGILE MATERIALS. Why do we need to understand the risks • That's one person hurt while working every minute. Globally, the International Labour Organisation estimates that one worker dies and a further 153 have accidents at work every 15 minutes. That equates to 2.3 million deaths and 313 million accidents every year. (Apr 28, 2015) • 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. Fall Protection No job is so important that it cannot be done safely UNDER NO CIRCUMSTANCES ARE PERSONS WORKING ON THIS SITE TO PUT THEMSELVES IN DANGER BEST - BE Safe Today Use of Ladders:- Always make 3 point contact Always Face the ladder When using the ladders, avoid overloading them. Do not rest a ladder on a weak surface. The ladder may topple from this action.. Lethal Ladder Hazards of Ladders: Don’t stand ladder on drum, box or other unstable bas Never attempt to repair broken ladders Ladder rungs must not be used as improvised ramps When using metal or metal- reinforced ladders, make sure there are no electrical hazards in the near vicinity Lethal Ladder “No matter how quickly a job can be done, there is always time to fall” Roof a risk place: If you can fall more than 2 meters, guardrails and toe boards must be erected Hazards resulting from adverse weather conditions must be anticipated, and suitable precautions taken Wet windy or Icy weather can seriously affect safety Scaffolding Using ladders or scaffolding without proper fixing is not safe. Never use incomplete scaffolding always inspect before use by competent person. Make sure there is safe access, hand rails and toe boards at all edges Things could fall on sites, wear your helmet Mobile Scaffold Tower Before Use: Ensure the tower is vertical and square Towers must not be used unless the wheels are locked Check that outriggers are set correctly and secured Ensure the platform is fully boarded out and guardrails and toe boards are fitted if working platform is over 2 meters Mobile Elevated work platform Mobile Elevated work platform Do not operate without pre-use inspection and unless you are trained Check condition of tyres, toe boards and guardrails, look for leaking hydraulic fluids Look out for overhead obstructions such as power cables, unstable ground, other equipment or personnel near-by Only use on firm level ground, make sure outriggers are properly extended and chocked before raising the platform Mobile Elevated work platform Always wear a safety harness secured to the platform by lanyard. Safety means staying in the basket and not climbing on the guardrails Place barricades and warning signs around the planned working radius Know what to do if machine fails with platform in raised position Fall Protection Fall Arrest: Limits free fall to within 2 vertical metres of the initiation point which reduces force by decreasing fall distance Consists of a(n) Lanyard Anchorage Point Full Body Harness Attachment Strap Fall Protection Lanyard A device made of rope, wire or nylon strap used to connect the individual to an anchorage point and stop the individual in the event of a fall Lanyards should: Be inspected prior to use Be protected against being cut or abraded Have a minimum breaking strength of 2270kg Be the appropriate length Be attached to an anchorage not to itself Fall Protection Full body harness: The attachment point of a body harness is located in the center of the wearer’s back near shoulder level Body belts are not allowed on sites Snap hooks shall be a double locking-type Fall Hazard Controls Hierarchy of Fall Hazard Control: • First line of defense • Eliminate the fall hazard • Second line of defense • Prevent the fall • Third and last resort • Control the fall Fall Hazard Controls Eliminate fall hazards – hole covers/grates • Very effective way to eliminate a fall hazard. • Designed to withstand intended load. • Secured-bolted, hinged, latched, locked Source: WVU Fall Hazard Controls Prevent the fall – guardrails • Standard railing • Top rail, mid rail, and posts • Height from upper surface of top railto floor level is 42” (+/− 3”) • Mid-rail height is 21” • Standard toeboard Source: OSHA • 3.5” high • Not more than ¼” clearance above the floo r Fall Hazard Controls Know the A, B, Cs of Personal Fall Arrest Systems • Anchorages • Body harness • Components (connectors like snaphooks or Deerings, connection points, lanyards, deceleration devices, lifelines, etc.) . Installed, used, and maintained according to the manufacturer Fall Hazard Controls PFAS – temporary anchorage PFAS- permanent A personal fall arrest system (PFAS) anchorage point must be capable of handling 5000 pounds. (2268 Kg) Fall Hazard Controls PFAS – connecting components Fall Hazard Controls Control the fall – safety net systems • Consists of specially designed mesh nets, panels, and connecting components • Must be designed, installed and maintained properly Source: OSHA Height safety Requirements • Your employer must inspect the: • workplace for existing and potential fall hazards • fall hazard controls used; such as guardrails, covers, grates, and anchorage points • You must inspect your PFAS, Positioning and Fall Restraint hardware before each use. Work At Height safety Requirements Rescue • Personal Fall Arrest Systems require a rescue plan • Employer must develop and communicate the rescue plan to all involved Source: OSHA Hazard Recognition Source of photo: OSHA Hazard Recognition Source of photo: OSHA THANK YOU 187/31/2023 54
