Study Notes

Work Platforms

A platform is required to work above floor level, which can be a ladder, scaffolding, or a stool.
A safe platform must be strong, stable, and have a good solid base.
Additional attachments may be required to a more stable structure depending on the height of the platform.
Follow Occupational Health and Safety Acts and Regulations, as well as plant-specific safety rules and policies.

Preventing Falling Objects

When working above the floor, falling objects can injure workers below.
Platforms must have a raised edge or toe plate to prevent objects from rolling off.
Heavy objects and parts being dismantled should be secured with a rope or chain before dismantling.
Wrenches and other tools should also be secured when not in use.
Warn people below of the hazard by posting a safety person, using warning signs, lights, or complete isolation of the area.

Safety Check

Never enter an area that is flagged or roped off for overhead work.

Ladders

Ladders are the most common way to access elevated work locations.
All ladders must meet Workers' Compensation Board regulations and be CSA approved.
There are two main types of ladders: step and rung.
Safety checks for ladders include:
- Inspecting for missing or loose steps or rungs.
- Checking for non-slip feet that are damaged or worn.
- Ensuring the ladder is stable and not overloaded.

Step Ladders

Step ladders have a series of flat step-like surfaces.
They are self-supporting, made of wood, aluminum, or fibreglass, and come in various heights.
Step ladders are easily damaged, so care must be exercised in their use.
Always inspect a step ladder before using it and look for defects such as:
- Missing or loose steps or rungs.
- Non-slip feet that are damaged or worn.
- Loose nails, screws, bolts, or nuts.

Rung Ladders

Rung ladders are not self-supporting and must rest against a support structure.
They come in various types and sizes, including portable and permanently fixed ladders.
Rung ladders must meet Workers' Compensation Board regulations and be CSA approved.
Inspect rung ladders before using them and look for defects such as:
- Gravity locks that are loose, broken, or missing.
- Properly lubricated working parts.
- Cords, chains, and ropes that are defective.

Scaffolding

Scaffolds are temporary structures made of posts, planks, and boards.
They are used to perform work from an otherwise inaccessible height.
Scaffolds must be designed and erected to meet CSA Standard CAN/CSA S269.2.
Always follow the more stringent requirements of the company or jurisdiction.
Scaffolds come in various styles, including single pole, double pole, tube and coupler, and fabricated frame scaffolding.
Scaffolds must be erected plumb and level on stable ground, with all connections securely fastened.

Scaffold Terminology

Familiarize yourself with scaffold terminology, including:
- Scaffold planks (boards)
- Bearer (transom)
- Longitudinal (façade) bracing
- Post (standard)
- Runner (ledger)
- Base plate
- Sill (sole board)

Safety Check

Never use a scaffold that is un-inspected, needs re-inspection, or is red-tagged.
Always use a hoist or rope to move materials to upper levels of a scaffold.
Never carry materials when climbing scaffolding.
Never allow tools, materials, or debris to accumulate on the work platform.
Never overload the scaffolding with too many people or materials in any one area.
Always make sure there is a safe entrance to all working levels.
Always barricade areas below if there is a chance of items falling from the scaffolding.

Work Platforms

A platform is required to work above floor level, which can be a ladder, scaffolding, or a stool.
A safe platform must be strong, stable, and have a good solid base.
Additional attachments may be required to a more stable structure depending on the height of the platform.
Follow Occupational Health and Safety Acts and Regulations, as well as plant-specific safety rules and policies.
