Collective means of protection for work at height are systems such as guardrails, walkways or another type of work platform, serving to prevent falls and which, in short, avoid the use of PPE specifically intended to protect against falls from height.
Why mount collective means of protection?
As established in the regulations and standards, the use of collective means of protection take priority over personal means of protective.

ISO 14.122-3 is the applicable industrial standard followed at Elytra.
This standard establishes that:
These are the different types of guardrails available at Elytra:
This is the most popular type installed by Elytra.

So, based on the application and the place of installation, walkways could be one of two types. Classes.
