2 WHAT HAPPENED WITH THESE PEOPLE? Fell from the height of his body (6 feet) 5 hour surgery Vertebrae disc removed Steel plates and screws in the neck and upper back Limited up & down movement for rest of life. Very active family man skiing, basket ball, etc. Fell & injured lower body skeletal structure Can trun,can tjump,can t even tie his shoe laces Hard on the family Husband and a father fell & hospitalized Bythetimefamilyreached died (brain hemorrhage). Son traumatized due to fathers death Had a happy family but it wasn t going to be the same forever

3 LADDER FALL FACTS Falls are the leading cause of unintentional injury mortality nationwide and ladder falls amounts to 43% of them. Ladder falls are the no.1 cause in construction & second leading cause of work related fatalities Increase in number of accidents is proportional to the increase in age of the worker Repeated handling of heavy, traditional equipment over reaching and improper set up use of the wrong type of ladder progressively add up to the chances of a ladder fall Ladder fall can result in minor bruises to severe injuries like impalement, spinal and cranial fractures as well. Workers Compensation never gets close to 50% of the actual financial security

6 WHAT IS LADDER SAFETY? Determining what type of ladder is APPROPRIATE for your current work environment Confirming that the ladder is the appropriate LENGTH for the task Checking that the ladder has proper DUTY RATING Thorough INSPECTION of the ladder to ensure it is in good working condition CLEAN the soles of your shoes to maximize traction and avoid slipping Confirm that the ground where ladder is set up is FIRM & LEVELED Confirm that surrounding DOORS & WINDOWS are blocked open, locked or properly guarded Ensure that the WEATHER is sufficiently safe for using the ladder Use NON CONDUCTIVE material like wood or fibreglass ladder for work around electricity or power tools Always maintain a 3 POINTcontact with the ladder while climbing NEVER CLIMB up to the extreme top of the ladder.

7 RATINGS FOR LADDERS RATING Type I-AA MAXIMUM LOAD 375 lbs USES Special duty industrial use, such as CATV, utilities, contractors, and higher capacity needs Although there are many different types of portable ladders, they all receive a rating based on the maximum intended or working load the total weight that they can safely support. This includes the weight of the worker, tools and material. Type I-A Type I 300 lbs. 250 lbs Extra-heavy-duty industrial use, such as utilities and contractors Heavy-duty industrial use, such as utilities and contractors These ratings must meet certain American National Standards Institute (ANSI) standards and they must be indicated on the duty rating sticker or manufacturer s label. Type II 225 lbs Medium-duty work, such as painting, offices for building maintenance, and light industrial use Type III 200 lbs Light duty work, such as household use ANSI requires that every ladder be labeled with this information so users can determine if they have the correct type of ladder for the task/job.

8 LADDER COMPOSITION LADDER COMPOSITION Property Stability Durability Strength-toweight ratio Weatherresistance Conductivity WOOD Better (heavier) Less Good Not as good Non-conductive when clean and dry FIBERGLASS Less (lighter) Better High Better Non-conductive when clean and dry (preferred) ALUMINUM/METAL Less (lightest) Better High Better Conductive do not use near exposed electrical sources Besides having different ratings or load capacities, ladders may be constructed of various kinds of materials usually wood, fibreglass or metal. Each material has specific care, maintenance and storage requirements and may be preferred for specific uses or under certain conditions. WOOD FIBRE GLASS METAL

9 Rules for Ladders Maintain ladders free of oil, grease and other slipping hazards Do not load ladders beyond their intended or rated load capacity Use ladders for their designated purpose only Use ladders only on stable and level surfaces Secure ladders placed in passageways, doorways or driveways Do not move, shift or extend ladders while in use Use ladders with non conductive side rails Face the ladder when moving up or down Do not carry objects or loads that could cause loss of balance and falling Use at least one hand to grasp the ladder when climbing (3 point contact) Keep areas clear around the top and bottom of ladders OSHA R Defective Ladders Portable ladders with structural defects such as broken or missing rungs, cleats or steps, broken or split rails, corroded components or other defective faulty components MUST immediately be marked defective or tagged DO NOT USE Ladder repairs must restore the ladder to a condition meeting its original design criteria before the ladder is returned to use.

11 POINT OF INFORMATION (FIBRE GLASS LADDERS) INCIDENT Two roofing technicians were going on to a flat roof toperformaninspectionandrepair.thefirst technician set up a 30 foot extension ladder to access the roof. The ladder was a Type IA Fiberglass ladder rated for a load capacity of 300 pounds. The technician weighed approximately 160 pounds. The ladder had been inspected and was less than 2 months old. The ladder had not been damaged or subjected to any harsh conditions. As the technician was climbing the ladder he felt the ladder start to give from underneath him. He was able to reach and hold on to the roof edge as the ladder collapsed. The second technician was able to get another ladder from their service truck, set the ladder up and get the first technician down safely without incident. Step Ladder Extension Ladder INVESTIGATION All fiberglass ladders were immediately brought in from the field and closely examined for any possible defects or damage. The company found that on approximately 20% of their fiberglass extension ladders there were very small cracks in the fiberglass on the side rails immediately next to the rungs of some ladders. In addition to the small cracks in the fiberglass in some areas the fiberglass material had split. FOLLOW UP The small cracks found in the side rails of the extension ladders were not noted to be in any pattern along the side rail. The cracks and splits in the fiberglass were found to be immediately next to the rungs on the outside portion of the side rail. It is believed the fiberglass may have been damaged or fatigued during the manufacturing process when the rungs were crimped into the side rail of the ladder.
