SPI and 3M give you advice on the changes of the CSA standard about working at heights

As you probably know, the CSA Z259 standard for working at heights has recently been revised and through all these changes, it’s easy to get lost.

The newly updated standard is an addition to the existing information found in the previous version and will have an impact on the selection, the use and the lifespan of fall protection equipment, such as energy-absorbing lanyards and horizontal lifelines.

Here is a glimpse of what’s changing:

A table, chart or graphic will now be required in equipment manuals to specify the range of weights and distances allowed for the device. This range, indicated by the manufacturers, will be based on the user’s weight and on the free-fall distance.

The objective of this additional information is to reduce users’ potential risk by given them the tools to easily know the range of their devices. This will protect every user of various weights to experience the same deceleration, ensuring a consistently lower exposure to peak forces.

Did you know that the new improved 3M™ DBI-SALA® Nano-Lok™ Personal Self-Retracting Lifeline is compliant with the new weight classes and standards?

Our world is continuously changing, worksites and CSA standards are evolving to meet these new realities and 3M™ Fall Protection Products are always improving to help keep you and your workers safe, no matter the job or the working conditions.
