Working Areas and Surfaces
Slips, trips, and falls on walking and working surface cause 15 percent of all accidental deaths in the construction industry.

Such accidents can be avoided if workers are aware of their surroundings and follow the rules on the site.

It is your responsibility to keep all walking and working surfaces clean and dry.


Floors can be hazardous in a number of ways:

• Ice, grease, oil, or wet processes can make them slippery.

• Tools, equipment, materials, or litter can clutter them.

• Unguarded opening in the floor or ground can cause fatal falls.


Wall openings are dangerous when they are not protected by guardrails or fences.


Platforms are work areas elevated above the floor or ground. These platforms, called open-sided platforms, are hazardous because they do not protect workers from falling over the edge.

To help prevent accidents, make sure platforms are dry and clear of materials and debris before stepping onto them.

Ramp and Runways:
The hazards of ramps and runways are similar to those of floors. Workers can trip on tools and equipment or slip on wet or icy surface.

There are some general guidelines that will help to avoid slips, trips, and falls on ramps and runway. Click on each number to know more:

Make sure the ramp is clear of tools, equipment, materials, or debris.

Check the surface before using it. If the ramp or runway is icy or wet, don’t use it until it is dry and free of ice. If ice cannot be removed wear shoes with skid-resistant cleats.

Make sure any tools or equipment you are carrying are turned off and secured. This will help prevent injuries if you fall.

The greatest hazard of using a ladder is falling. The following safe practices can help prevent slips and falls from ladders:

• Use appropriate fall protection.

• Wear safe, strong work boots that are in good condition.

• Watch where you step. Be sure your footing is secure.

• Maintain clean, smooth walking and working surfaces. Fill holes, ruts, and cracks.

• When climbing ladders, always face the ladder and use both hands.

• Clean up slippery material.

• Pick up any litter around a ladder.

• If you must climb to reach something, use a ladder that has been safely set up and properly secured at the top and the bottom.

• Always maintain a three-point contact with the ladder: one hand and two feet or two hands and one foot.

• Don’t overreach from a ladder. Climb down and move the ladder to the desired position.

Scaffolding supports workers and materials on elevated platforms. It is generally used on multi-storey buildings or structures.

Weather conditions, poor housekeeping, and carelessness can make working on scaffolding very dangerous.

Walking and working on roofs present two different kinds of risks: falling through an opening such as skylight or vent, and falling off the roof.

Weather hazards, poor housekeeping, or carelessness can cause these accidents.

The next slide presents the guidelines that should be followed to ensure your safety when working on a roof.

Working Areas and Surfaces
Click on each button to know the guidelines that will help ensure your safety when working on a roof:

Wear appropriate fall protection, even on shallow-pitch roofs.

Wear boots or shoes with rubber or crepe soles that are in good condition.

Rain, frost, and snow are all dangerous because they make a roof slippery. If possible, wait until the roof is dry. Otherwise, wear special roof shoes with skid-resistant cleats in addition to wearing fall protection.

Brush or sweep the roof periodically to remove any accumulated dirt or debris.

On pitched roofs, install the necessary roof brackets and toe boards as soon as possible. These brackets and toe boards can be removed and repositioned when shingle-type roofing is installed.

Remove any unused tools, cords, and other loose items from the roof. They can be a serious hazard.

Be alert to any other potential hazards, such as live power lines.

Use common sense. Taking chances can lead to injury or death.
