What are Guardrails?
Guardrails are a stationary (or "fixed") system used to protect workers from falls when working at heights. Guardrails are a preferred means of protecting workers because the system does not rely on the worker to be trained to use, inspect, and wear a fall protection system.
Well built guardrails are a reliable and convenient means of fall protection because they act as a visible and physical barrier to help prevent falls from heights or between levels including falls from roofs, balconies, stairwells or falls into open holes. Guardrails are used where covers, floors or walls cannot be installed or are not practical.
Guardrails are used in every industry and can be seen in:
- Retail shops.
- Industrial settings.
- Construction sites.
- Warehouses.
- Shipping facilities.
- Landscaping and work areas in natural settings.
- Any workplace with an accessible rooftop.
