HEIGHT

A place is at height, if a person could be injured falling from it, even if it is at or below ground level.Falls from height are responsible for many serious and fatal injuries every year in different industries.If a person fall from height above two meters there is a likelihood of sustaining injury. Many work activities involve working at height. Working from ladders, scaffolds and platforms are some of the examples.


HAZARD ASSOCIATED WITH WORKING AT HEIGHT
The main hazard associated with working at height are people falling and objects falling onto people below. These may occur as a result of adequate edge protection, or from objects being poorly secured.

RISK ASSOCIATED WITH WORKING AT HEIGHT
If working at height cannot be avoided, hazards associated with working at height shall be identified and mitigated prior to beginning work.

STEP1
Look for hazard associated with falls from height around the workplace. Where are people required to work at height? Do they carry out work from ladders, platforms, scaffolds, or unprotected or fragile roofs.

STEP2
Decide who might be harmed and how. Who comes into the workplace? Are they at risk?

STEP3
Consider the risk. Are there ready measures in place to deal with the risk? If measures are not in place, develop an action plan to address the risk.

STEP4
Assign responsibility for the action plan.

GOOD PRACTICES WHEN WORKING AT HEIGHT
Ladders are acceptable only for access or work of short duration.They should be:

Erect a ladder at an angle of 75 degrees with the floor or the horizontal distance from the wall to the

foot of the ladder should be one –fourth the working length.

Secure (preferably at the top) or footed.

Positioned close to the job to avoid over-reaching .

Sufficiently protected at the base of the ladder or access equipment to prevent pedestrian or vehicles bumping into them.

USE OF STEP LADDERS
When using a step ladder the following precaution should be considered.

Always spread them to their full extent and lock them off.

Do not work on the top platform

Do not use the top tread, tool shelf or rear part of the steps as a foot support.

Only one person should be on the ladder at any one time.

The ladder must be appropriate and of the correct grade for the intended use.

MOBILE ELEVATED WORK PLATFORM

Use the platform only on level ground.

Work with a trained operator at ground level

Safety harnesses must be worn while on the platform.

Keep the platform within safe working linits and radius, taking account of wind speeds.

SCAFFOLD TOWERS
Scaffold towers should:

Be erected by competent persons.

Have stabilizers deployed as necessary to meet the correct height to base ratio.

Have all casters firmly locked before use.

Have ladders access to working platform

Never be moved while the tower is occupied.

Be regularly inspected and maintained.

FALL ARREST SYSTEMS

Designed to support and hold a person in the event of  a fall.

Not designed to support a person while working.

Must always be used as a last resort.

Put in a place emergency rescue procedure before use.

Ensure anchorage point is above the head of worker where practical.

SLIP, TRIP AND FALLS
A slip occurs when there is little traction or friction between the shoe and walking surface.

A trip occurs when a person’s foot contacts an object in their way or drops to a lower level unexpectedly, causing them to be thrown off-balance.

A trip most often results in a person falling forward.

A fall occurs when you are too far off balance.

CAUSES OF SLIP TRIP AND FALL

Wet or slippery surface: Wet or slippery surfaces are major causes of slip. Highly polished floors such as marble, terrazzo, or ceramic tile can be extremely slippery even when dry.

Insufficient lightening

Insufficient light can make it difficult to see obstacles and notice changes in the walking surface.

Move slowly where slowly where light is dim and pay increased attention to your path of travel.
Changes in Elevation

Changes in elevation are a major source of trip incidents. A change in walking surface of ¼ -1/2 “ or greater will be sufficient to cause a trip.

Climbing or Descending Stairways

Keeping stairs in good shape is essential to preventing incidents. Make sure that stairways have

secure handrails and guardrails, even surfaces, even tread heights and are free of deteriorating
coverings such as a frayed carpet.

HOW TO PREVENT SLIP, TRIP AND FALL

Ensure every floor, working place, and  passageway  are kept free from protruding nails, splinters, holes, loose boards.

Wear slip resistance footware to maximize traction.

Provide warnings where slip/fall hazard has been identified.

Keep passageways, storerooms, and service rooms clean, orderly and free of obstructions that could create hazard.

Use mats and runners in areas where individuals may encounter slippery contaminants or foreign materials on the floor surface.
