LADDER FALL FACTS

Falls are the leading cause of unintentional injurymortality nationwide and ladder falls amounts to43% 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 theincrease in age of the worker

Repeated handling of heavy, traditional equipment –over‐reaching and improper set up – use of the wrongtype of ladder progressively add up to the chances ofa ladder fall

Ladder fall can result in minor bruises to severeinjuries like impalement, spinal and cranial fracturesas well.

Workers’ Compensation never gets close to 50% ofthe actual financial security

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‐CONDUCTIVEmaterial like wood or fibreglass ladder for work around electricity or power tools Always maintain a 3 – POINT contact with the ladder while climbing NEVER CLIMB up to the extreme top of the ladder. 

WHAT IS LADDER SAFETY?

RATINGS FOR LADDERS

RATING MAXIMUMLOAD USES

Type I-AA 375 lbs Special duty industrial use, such as CATV, utilities, contractors, and higher capacity needs

Type I-A 300 lbs. Extra-heavy-duty industrial use, such as utilities and contractors

Type I 250 lbs Heavy-duty industrial use, such as utilities and contractors

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

Although there are many different types of portableladders, they all receive a rating based on the maximumintended or working load – the total weight that theycan safely support. This includes the weight of theworker, tools and material.

These ratings must meet certain American NationalStandards Institute (ANSI) standards and they must beindicated on the duty rating sticker or manufacturer’slabel.

ANSI requires that every ladder be labeled with thisinformation so users can determine if they have thecorrect type of ladder for the task/job.

LADDER COMPOSITION

LADDER COMPOSITION

Property Stability Durability Strength-to-weight ratio

Weather-resistance 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, laddersmay be constructed of various kinds of materials – usuallywood, fibreglass or metal. Each material has specific care,maintenance and storage requirements and may bepreferred for specific uses or under certain conditions.

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

Defective Ladders – Portable ladders with structural defects – such as

broken or missing rungs, cleats or steps, broken orsplit rails, corroded components or other defectivefaulty components – MUST immediately bemarked defective or tagged “DO NOT USE”

Ladder repairs must restore the ladder to acondition meeting its original design criteriabefore the ladder is returned to use.

Extension Ladder

Step Ladder

INCIDENT –Two roofing technicians were going on to a flat roof to perform an inspection and repair. The firsttechnician set up a 30 foot extension ladder to access the roof. The ladder was a Type IA Fiberglass ladderrated for a load capacity of 300 pounds. The technician weighed approximately 160 pounds. The ladderhad been inspected and was less than 2 months old. The ladder had not been damaged or subjected to anyharsh conditions. As the technician was climbing the ladder he felt the ladder start to give fromunderneath him. He was able to reach and hold on to the roof edge as the ladder collapsed. The secondtechnician was able to get another ladder from their service truck, set the ladder up and get the firsttechnician down safely without incident.

INVESTIGATION –All fiberglass ladders were immediately brought in from the field and closely examined for any possibledefects or damage. The company found that on approximately 20% of their fiberglass extension laddersthere were very small cracks in the fiberglass on the side rails immediately next to the rungs of someladders. 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 alongthe side rail. The cracks and splits in the fiberglass were found to be immediately next to the rungs on theoutside portion of the side rail. It is believed the fiberglass may have been damaged orfatigued during the manufacturing process when the rungs were crimped into theside rail of the ladder.
