An Indispensable tool in building-ladder

by: zhongxinladder   Keywords: ladders

The following rules apply to all ladders:
 Maintain ladders free of oil, grease and other slipping hazards.
 Do not load ladders beyond their maximum intended load nor beyond their manufacturer’s rated capacity.
 Use ladders only for their designed purpose.
 Use ladders only on stable and level surfaces unless secured to prevent accidental movement.
 Do not use ladders on slippery surfaces unless secured or provided with slip-resistant feet to prevent accidental movement. Do not use slipresistant feet as a substitute for exercising care when placing, lashing or holding a ladder upon slippery surfaces.
 Secure ladders placed in areas such as passageways, doorways or driveways, or where they can be displaced by workplace activities or traffic to prevent accidental movement. Or use a barricade to keep traffic or activity away from the ladder.


 Keep areas clear around the top and bottom of ladders .
 Do not move, shift or extend ladders while in use.
 Use ladders equipped with nonconductive side rails if the worker or the ladder could contact exposed energized electrical equipment.
 Face the ladder when moving up or down.
 Use at least one hand to grasp the ladder when climbing.

 

 

 

 

 Do not carry objects or loads that could cause loss of balance and falling. In addition, the following general requirements apply to all ladders, including ladders built at the jobsite:


Double-cleated ladders or two or more ladders must be provided when ladders are the only way to enter or exit a work area where 25 or more employees work or when a ladder serves simultaneous two-way traffic.
 Ladder rungs, cleats and steps must be parallel, level and uniformly spaced when the ladder is in position for use.
 Rungs, cleats and steps of portable and fixed ladders (except as provided below) must not be spaced less than 10 inches (25 cm) apart, nor more than 14 inches (36 cm) apart, along the ladder’s side rails.


 Rungs, cleats and steps of step stools must not be less than 8 inches (20 cm) apart, nor more than 12 inches (31 cm) apart, between center lines of the rungs, cleats and steps.
 Rungs, cleats and steps at the base section of extension trestle ladders must not be less than 8 inches (20 cm) nor more than 18 inches (46 cm) apart, between center lines of the rungs, cleats and steps. The rung spacing on the extension section must not be less than 6 inches (15 cm) nor more than 12 inches (31 cm).


 Ladders must not be tied orfastened together to create longer sections unless they are specifically designed for such use.
 When splicing side rails, the resulting side rail must be equivalent in strength to a one-piece side rail made of the same material.
 Two or more separate ladders used to reach an elevated work area must be offset with a platform or landing between the ladders, except when portable ladders are used to gain access to fixed ladders.
 Ladder components must be surfaced to prevent snagging of clothing and injury from punctures or lacerations.
