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.
