Collective restraint systems
Collective restraint systems are passive safety systems designed to stop personnel from falling when working from significant heights. Once collective restraint systems have been installed, they do not require workers to take proactive measures in order to be safe. This is why they are considered passive safety measures.
Unlike personal fall arrest or fall prevention systems, collective restraint systems protect numerous workers across a large area. To protect personnel working in high-risk areas, systems should be at least 1.2m high and placed around the perimeter of the area.
Systems can include:
- Guardrails. A guardrail is a longitudinal barrier that prevents people from falling or straying into a dangerous or restricted zone.
- Barriers or guardings. These are structures – either raised rails, parapets or walls – that deny access to unsafe areas
- Purlin trolleys. Purlin trolleys provide workers with a safety deck to walk on and protect them from exposure to edging. They are frequently used in roofing installations.
