FAQ
Frequently Asked
What is a Safety-Net?
A Safety-Net is a fall protection system that sits beneath manhole covers. When the cover is removed for access, the net prevents workers, pedestrians, or equipment from accidentally falling into the open chamber.
What load can Safety-Nets support?
Safety-Nets are independently tested to 150kg without failure. This provides reliable fall protection for workers accessing manholes and chambers.
Are Safety-Nets required by law?
While specific requirements depend on the work situation, NZ health and safety regulations require hazard management at open excavations and chambers. Safety-Nets provide an effective control measure for fall hazards.
How do Safety-Nets attach?
Safety-Nets use a four-point snap-clip attachment system that connects to the Wunder-Cover frame. Installation takes seconds and requires no tools.
Can Safety-Nets be used with non-Wunder-Cover manholes?
Safety-Nets are designed for Wunder-Covers but may be adaptable to other manhole types. Contact us to discuss compatibility with your specific application.
Are Safety-Nets reusable?
Yes. Safety-Nets are designed for repeated installation and removal. The durable polyester netting and stainless steel fixings withstand regular use.
What happens if someone falls on the net?
The net is tested to 150kg and will catch the person, preventing them from falling into the chamber. The snap-clip system and frame support distribute the load safely.
Can the net be secured against tampering?
Yes. The anti-tamper bolt down systems are available POA
ABOUT ATS SAFETY-NETS
Open manholes and inspection chambers are high-risk hazards on work sites. Falls into chambers cause serious injuries and fatalities. When covers are removed for maintenance or inspection, immediate fall protection is essential.
THE RISK
Workers, pedestrians, or equipment can fall into open chambers. Even experienced workers can lose footing or misjudge the opening, particularly on busy sites or in poor visibility. The consequences are severe – falls of 2+ meters into confined spaces often result in serious injury.
APPLICATIONS
Essential for council maintenance crews, contractors, utility companies, and facilities managers who regularly access manholes and chambers. Particularly important in high-traffic areas, pedestrian zones, or sites with multiple workers.
COMPLIANCE
NZ health and safety regulations require hazard management at open excavations and chambers. Safety-Nets provide a practical, cost-effective control measure that demonstrates proactive safety management.
