  • Care and Use of Ladders.

    • Maintenance programs are very important.

    • Inspect frequently and those which have developed defects shall be withdrawn from service for repair or destruction and tagged or marked as "Dangerous, Do Not Use."

    • Ladders shall be maintained in good usable condition at all times

    • Hardware fittings and accessories shall be checked prior to use and kept in good working condition.

    • When ladders are to be subjected to deteriorating agents, a protective coating shall be applied to the equipment.

    • The joint between the steps and side rails shall be tight, all hardware and fittings securely attached, and the movable parts shall operate freely without binding or undue play.

    • Metal bearings of locks, wheels, pulleys, etc., shall be frequently lubricated.

    • Frayed or badly worn rope shall be replaced.

Ladders

  • Safety feet and other auxiliary equipment shall be kept in good condition to insure proper performance.

  • Rungs shall be kept free of grease and oil.

  • Portable ladders shall be so placed that the side rails have a secure footing. The top rest for portable rung and cleat ladders shall be reasonably rigid and shall have ample strength to support the applied load.

  • Ladders shall not be placed in front of doors opening toward the ladder unless the door is blocked open, locked, or guarded.

  • Ladders shall not be placed on boxes, barrels, or other unstable bases to obtain additional height.

  • Ladders with broken or missing steps, rungs, or cleats, broken side rails, or other faulty equipment shall not be used.


Ladders2
Ladders

  • On two-section extension ladders the minimum overlap for the two sections in use shall be as follows:

    Size of Ladder (Feet) Overlap (Feet)

    Up to and including 36............................... 3

    Over 36 up to and including 48................... 4

    Over 48 up to and including 60....................5

  • Roof access: the top of the ladder extends at least 3 feet above the point of support at eave, gutter, or roof line.

  • Non-slip bases when there is a hazard of slipping. Non-slip bases are not intended as a substitute for care in safely placing, lashing, or holding a ladder that is being used upon oily metal, concrete, or slippery surfaces.


Ladders3
Ladders

  • Ladders shall not be used as a brace, skid, guy or gin pole, gangway, or for other uses than that for which they were intended, unless specifically recommended for use by the manufacturer.

  • Electrical Hazards. Portable metal ladders shall not be used in the vicinity of electrical circuits in places where they may come in contact with them. Portable metal ladders shall be legibly marked with signs reading “CAUTION--Do Not Use Around Electrical Equipment,” or equivalent wording.

  • Articulating Boom - An aerial device with two or more hinged boom sections.

  • Elevating Work Platform - A device designed to elevate a platform in a substantially vertical axis. (Vertical Tower, Scissor Lift, Mast-Climbing Work Platform)


Other ways to elevate employees1
Other Ways To Elevate Employees safety codes apply. The ANSI codes are as follows

  • Equipment Instructions & Markings

    • Each unit shall have a manual containing instructions for maintenance and operations in a weather resistant storage location on the elevating work platform or aerial device.

    • Each aerial device or elevating work platform placed in service prior to December 23, 1999 shall have a conspicuously displayed legible plate or other legible marking verifying the aerial device or elevating work platform is designed and manufactured in accordance with applicable specifications.


Other ways to elevate employees2
Other Ways To Elevate Employees safety codes apply. The ANSI codes are as follows

  • Operating Instructions For Elevating Work Platforms

    • Can we ride in them???? Maybe.

      • The travel speed at Maximum Travel Height limited to 3 feet (0.9m) per second.

      • Self-propelled units shall be equipped with electrical or other interlock means which will prevent driving them with the platform height greater than the Maximum Travel Height or at speeds greater than permitted at Maximum Travel Height.

      • The surface upon which the unit is being operated is level with no hazardous irregularities or accumulation of debris which might cause a moving platform to overturn.

      • (Exception: TV and Movie Camera Booms.)


Other ways to elevate employees3
Other Ways To Elevate Employees safety codes apply. The ANSI codes are as follows

  • Other operating safety rules:

    • Employees shall not sit, stand or climb on the guardrails of an elevating work platform or use planks, ladders, or other devices to gain greater working height or reach.

    • Where moving vehicles are present, the work area shall be marked with warnings such as flags, roped off areas or other effective means of traffic control shall be provided.

    • In operations involving production of small debris, chips, etc., and the use of small tools and materials, and where persons are required to work or pass under the equipment, screens shall be required between toeboards and guardrails.
