Q: The internal fibres (core yarns) of a Polyester Roundsling may be repaired with knots if they were to become cut.

False. Knots are prohibited in any part of the sling. If a Polyester Roundsling were to become damaged or the core yarns cut, the sling must be immediately removed from service. Refer to the ASME Standard B30.9 – Chapter 6.9 Polyester Roundslings for more detailed information on inspection, removal and repair criteria for Polyester Roundslings.

Q: The rated load capacity of a Polyester Roundsling may be reduced if used around small diameters.

True. When used around a small diameter or edge radius, the sling is forced into a sharp bend which increases tension and stress on the internal fibres. This is called “point loading” and may cause the sling to fail. Refer to the ASME Standard B30.9 chapter 6.10 Polyester Roundslings for more information on operating practices and sling selection.  

Referenced

Q: It is acceptable to use a Polyester Roundsling that has holes in its cover as long as the holes are small.

These conditions cause uneven loading across the width of the sling which would significantly reduce the slings rated capacity. Refer to the ASME Standard B30.9 – Chapter 10.4 Rigging Practices for Polyester Roundslings for more detailed information.

Referenced

Q: A Polyester Roundsling can be shortened by tying knots in it.

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.

Find an assortment of rigging related toolbox talks ready to be used below.

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.

riggingresource.com is a comprehensive online resource developed for new and experienced workers with the operation of cranes and rigging equipment. Industry leaders, employers, workers, and students now have a wealth of information available at their fingertips.

This site can provide knowledge that will help to ensure the proper use of rigging equipment during rigging procedures, and help to identify and avoid workplace hazards.

Using the simple search and navigation features of the website, fun quizzes, and informational pop-ups, you will become informed about proper operational and workplace regulations and standards that comply with Alberta Occupational Health & Safety (OH&S) and the American Society of Mechanical Engineers (ASME).
