Working at Heights Refresher
(Ontario CPO Approved)


Program Description

Ontario's CPO-approved Working at Heights Refresher training program is a comprehensive safety training course designed to prevent falls from heights in the workplace. The program is intended for workers, supervisors, and employers who are responsible for the safety of those who work at heights in construction.

Construction Regulation 213/91 requires anyone working at heights to have received training from a CPO-approved training provider. The regulation applies to all construction projects, including new construction, renovation, and demolition projects.

The course covers the following topics:

  1. Barriers and Other Fixed Equipment: Participants will learn about fixed barriers and other equipment used to prevent falls from heights. This may include guardrails, safety nets, floor covers, and other engineering controls designed to provide a physical barrier between workers and hazards.

  2. Personal Fall Protection Equipment: Personal fall protection equipment is a key component of the Working at Heights program. Participants will learn about different types of personal fall protection equipment, including harnesses, lanyards, and self-retracting lifelines. They will learn how to select and use the appropriate equipment for the job, as well as how to properly inspect and maintain this equipment. The importance of maintaining 100% tie off is also thoroughly reviewed.

  3. Anchor Points: Anchor points are critical to the effective use of personal fall protection equipment. Participants will learn about the different types of anchor points, including fixed and temporary anchor points. They will also learn how to select and use the appropriate anchor point for the job, as well as how to properly inspect and maintain anchor points.

  4. Work Access Equipment and Platforms: Work access equipment and platforms are often used to provide safe access to elevated work areas. Participants will learn about the different types of work access equipment and platforms, with a primary focus on aerial work platforms such as scissor lifts and boom lifts. They will learn how to select and use the appropriate equipment for the job, as well as how to properly tie off.

  5. Rescue Planning: Participants will learn about the importance of having a rescue plan in place in the event of a fall from heights. This includes identifying the appropriate rescue equipment and personnel, establishing communication protocols, and developing emergency response procedures. Participants will learn how to assess the risks associated with falls and how to develop a rescue plan that ensures a timely and effective response.


Throughout the course, participants will have the opportunity to practice and demonstrate their understanding of the material through hands-on exercises, case studies and assessments. Upon completion of the course, participants will receive a certificate of completion and will be equipped with the knowledge and skills needed to work safely at heights.
