Testing Your Knowledge

Comprehensive training is a continuous process that extends beyond initial orientation. To assist in the ongoing education of workers, we have developed a series of short, product-specific quizzes designed to reinforce key safety principles and technical standards. These quizzes serve as an effective self-assessment tool or as a supplementary training resource to ensure that personnel maintain a high level of proficiency when handling rigging equipment. By validating theoretical knowledge alongside practical application, employers can better support a safe, competent, and compliant worksite.

Test your understanding of rigging standards and best practices with our product quizzes below.

Fulfilling Your Responsibility

A toolbox talk (or toolbox meeting) is a short, focused safety discussion held on the worksite to reinforce key hazards, review safe work practices, and address issues relevant to the tasks at hand. It is considered a supplementary form of training because it supports, but does not replace, the formal education and instruction required under Alberta’s Occupational Health and Safety Act, Regulation, and Code.

Alberta legislation requires employers to ensure that workers are competent to perform their jobs safely and are provided with the training, supervision, and information needed to protect their health and safety. Toolbox talks help employers meet these responsibilities by keeping safety knowledge fresh and encouraging regular communication.

They also support workers’ legislated rights to know about hazards, participate in health and safety discussions, and express concerns about unsafe conditions. By involving workers directly in these brief, practical conversations, toolbox talks strengthen shared responsibility and help maintain a safe and informed worksite.

Quick Reference: Verified Competence

Workers conducting tasks related to rigging must have the knowledge, training, experience, skills and physical ability to conduct the work safely and as required by their employer..  For more information on personal competence, refer to the applicable ASME B30 Standard. 

Per the Alberta OHS Code, a competent person is someone who is trained, qualified and has experience completing rigging tasks safely on their own, without supervision. 

  • Qualified means: someone who has earned their qualifications through a formal education program or acquired them through a combination of education and practical experience.
  • Trained means: training was received that was appropriate to the tasks, equipment and environment in which they will be performed or used.
  • Experienced means: a person has sufficient and adequate knowledge to perform the task with little or no supervision. 

While these are essential components of competence, a worker’s qualifications, training, and experience alone do not guarantee that work will be performed safely each time. It is the employer’s responsibility to conduct training and competency assessments at periodic intervals.

Below are competency evaluation forms that can be used by an employer or supervisor to assess a worker’s competency when conducting tasks involving rigging and rigging equipment.
