*WORK AT HEIGHT

*WHAT IS WORK AT HEIGHT?How do we define Work at Heights?

*Working at Heights or Elevated Works is considered when any work is carried out at 1.8 meters (6ft.) and higher or working on one or more of the following:

High Steel StructuresRoof TopsScaffoldsLaddersFloor Openings

* moving from one surface to another at heights; uncovered holes and openings; open ledges not barricaded; uneven surfaces; moving surfaces; poor lighting; unsuitable foot wear; slippery surfaces; wind, rain and ice; being struck by falling objects; incorrectly using a ladder; and incorrectly using fall arresting equipment.

FACTORS AND SITUATIONS THAT COULD CAUSE A FALL:

*Supervisors are responsible to ensure that employees receive training on:proper use; care; inspection; and limitations; of all

Fall Protection Equipment. Supervisors are responsible to ensure that the proper equipment is available for employee use.

Supervisors are responsible to monitor employee use of Fall Protection devices to ensure that all requirements of this procedure are maintained.SUPERVISORS RESPONSIBILITIES

*INSPECT THE JOB FIRST !Before each task is started, visit where you will be working.

Check for drop hazards, overhangs.

Check to make sure that no welding takes place above while you are working below a walkway.

*PORTABLE LADDERS The most commonly used and abused equipment for working at heights is the Portable ladder.

The main types of Portable Ladders commonly used are the:

1. Single ladder;

2. Extension Ladder; &

3. Step Ladder.

*POSITIONING PORTABLE LADDERS Ladders should be positioned on a firm, level surface at an angle of 75 degrees.

You should never position a ladder:

in front of outward opening doors;against a window pane;on top of boxes, loose bricks or concrete blocks to gain extra height.

*PORTABLE LADDERS The end of the ladder extends at least 1 meter (3 Ft.) past the landing platform or step off point.

The ladder must have secure footing on level ground / surface.

Secure the ladder at the top to prevent slipping & falling.1 meter

*PORTABLE LADDERS Use both hands when climbing the ladder.

Always maintain a minimum three point contact with the ladder;

Use a hand-rope to haul tools up to your work platform.

*Twisted or deformed ladder partsLoose or missing screws and rivetsSharp edges and burrsMetal fatigue and cracksCorrosion due to contact with acids or caustic sodaCHECKING METAL LADDERS

*CHECKING SINGLE TYPE LADDERS

*PERSONAL FALL ARREST SYSTEMBODY BELTNOT ALLOWED

(Use it only as restraint device to limit the movement at dangerous places)

*PERSONAL FALL ARREST SYSTEM Destroy any equipment which has received a shock load.Never use equipment for other than personal fall protection.To protect from accidental disconnection ("roll out") only use lanyards with double locking snap hooks.Do not interconnect snap hooks for doubling the length of the lanyard.Connect the lanyard to a solid anchor point and do not expose yourself to a fall on the lanyard greater than 6 feet.Inspect you fall protection equipment prior to use daily.Lanyards must be equipped with shock absorber.

* SCAFFOLD FATALITIES FALLS PRIMARY CAUSE

*GENERAL SCAFFOLD REQUIREMENTS

*Weight Capacity - all scaffolds must be capable of supporting 4 times the intended load.A scaffold expected to hold a 200 lb man and 20 lbs of tools and materials must be designed to support 880 lbs without failure.A scaffold must never be loaded beyond its maximum capacity.GENERAL SCAFFOLD REQUIREMENTS

*Top-RailMid-RailSpare PipeToe-Board

*Platforms - rest platforms every 12 feetBuilt in access rungs must:be specially designed by the manufacturer as a ladder runghave rung length of at least 12be uniformly spacedhave maximum vertical spacing of 12 GENERAL SCAFFOLD REQUIREMENTS

*ERECTION AND USE

*GENERAL SAFETY GUIDELINES DURING ERECTIONScaffolds shall be erected under the supervision of a competent person, and performed by a trained crew selected by the competent person.Personal Protective EquipmentSoil TypesBase PlatesPlumb, level, and square scaffold at base

*GENERAL SAFETY GUIDELINES DURING ERECTIONRAISING AND LOWERING SCAFFOLD MATERIALSShould be done using an approved hoisting appliance (e.g. - gin wheel)Throwing is strictly prohibited.The area on the ground level beneath the material being raised shall be barricaded and a sign displayed prominently.All timber planks intended to be raised or lowered by rope shall be secured by a timber hitch or clove hitch with a half hitch on the main hauling part.

*RAISING AND LOWERING SCAFFOLD MATERIALS

*SCAFFOLD TAGGINGAll scaffold shall be tagged COMPLETE, INCOMPLETE, DANGER - DO NOT USE.

What makes an INCOMPLETE scaffold?Missing guardrailsIncomplete decking

What makes a DANGER - DO NOT USE scaffold?Cracks in frameExcessive rustScaffold not plumbScaffold has missing parts

*UNIVERSAL SCAFFOLD TAGS

*SCAFFOLD USEScaffold users must comply with all federal, state, and local regulations when using a scaffold. User must inspect scaffold before use.Always use the safe means of access provided.Do not work from scaffold if you feel dizzy or weak.Do not climb or use as access bracing or frame.Climb carefully.Do not alter or move the scaffold while it is in use, except by a trained crew under the supervision of a competent person.

*Use special precautions to protect the scaffold members when working with a heat producing tool. Maintain scaffold in a safe condition.Do not use scaffold as a material hoist.Clean up spills immediately.Use tag line to hoist materials onto a scaffold.Do not allow tools, materials, or debris to accumulate. Ensure thorough housekeeping.SCAFFOLD USE

*Maintain clearance from power lines as follows:Insulated lines: less than 300 volts - 3 feet300 volts to 50 KV - 10 feetMore than 50 KV - 10 feet plus 4 inches for each 1 KV over 50 KVSCAFFOLD USE
