    Study Notes

    Introduction to Elevating Work Platforms in Construction

    • The Elevating Work Platforms in Construction program includes a Trainer's Guide, User's Guide, and Proof-of-training card.
    • The program is designed to provide training for operators of elevating work platforms.

    Training Requirements

    • Basic training in Elevating Work Platforms in Construction must be supplemented with specific training on the class of platform being used.
    • In addition to basic training, operators must also receive training on the specific platform they will be using.
    • Operators must receive training before operating an elevating work platform for the first time.

    Proof-of-training Card

    • The Proof-of-training card is a document that proves an operator has received training on elevating work platforms.

    Elevating Work Platforms in Construction Program

    • The program consists of two components: basic training and platform-specific training.
    • The User's Guide outlines how to conduct effective training.

    Elevating Work Platforms

    • CSA B354.2 covers several types of elevating work platforms, including scissor lifts and boom lifts.
    • Scissor lifts are raised and lowered by hydraulic pistons and an expanding scissor mechanism.
    • O1-slab models are typically used on smooth surfaces.
    • Rough-terrain units are designed to handle rugged off-slab challenges.
    • On-slab units typically have solid tires, while rough-terrain units have pneumatic tires.
    • Some rough-terrain units have additional features for extra stability.

    Safe Operation

    • Before operating a scissor machine, operators must ensure the surrounding area is clear and the platform is leveled.
    • Operators must stay within the platform's rated capacity.
    • Operators must be careful when handling materials on the platform.
    • Machine tipping or overturning can be caused by overloading or uneven surfaces.

    Hazards

    • Common hazards related to elevating work platforms include overloading, uneven surfaces, and accidental contact.
    • Operators should not disarm safety features, such as the tilt or level warning or the deadman switch.
    • Accidental contact can be caused by poor visibility or lack of attention.

    Maintenance and Inspection

    • Elevating work platforms must be regularly inspected and maintained to ensure safety.
    • The maintenance and inspection tag should be attached to the platform and include information on inspections, tests, repairs, and maintenance.
    • The owner or supplier is responsible for keeping a log of inspections, tests, repairs, and maintenance.

    Regulations

    • Ontario's Occupational Health and Safety Act outlines the requirements for operating elevating work platforms.
    • The construction regulation includes standards for elevating work platforms, such as CSA B354.2.
    • The owner or supplier is responsible for ensuring the platform is marked with its rated capacity.

    Safety Precautions

    • Operators must wear a body harness while the platform is being moved.
    • The work area should be properly marked and cordoned off.
    • Operators must be aware of their surroundings and stay within the platform's rated capacity.

    Stability

    • Stability is critical when operating elevating work platforms.
    • The centre of gravity is the point where the platform's weight is concentrated.
    • The tipping axis is the point where the platform can tip over.
    • Tipping can be caused by overloading, uneven surfaces, or sudden movements.

    Operator's Responsibilities

    • Operators must ensure the platform is properly inspected and maintained before use.
    • Operators must follow the operator's manual and Proof-of-training card guidelines.
    • Operators must be aware of their surroundings and stay within the platform's rated capacity.
