What material should safety nets be made of?

High-tenacity synthetic fibres like polyamide (nylon) or polypropylene, which are resistant to rot and mildew (Clause 4.1).

What is the maximum allowed mesh size for a personnel safety net?

The mesh size shall not exceed 100 mm x 100 mm (Clause 5.1.1).

How is the strength of a safety net tested?

A sample net must withstand the impact of a 100 kg mass dropped from a height of 6 m without breaking (Clause 8.3).

What information should be marked on a safety net?

The net must be marked with the manufacturer's name, date of manufacture, material type, and the number of this standard (Clause 10.1).

This standard specifies the material, construction, performance, and testing requirements for safety nets made from synthetic fibres. These nets are intended for use in construction and other works to protect workers from falling from heights.

Specifies requirements for safety nets used to prevent or mitigate injuries from falls in construction areas.

Quick Reference Values

Maximum mesh size100 mm

Minimum breaking strength of mesh rope2.0 kN

Minimum breaking strength of border rope30.0 kN

Test mass for dynamic load test100 kg

Drop height for dynamic load test6 m

Minimum overlap between adjacent nets300 mm

Practical Notes

Nets should be installed as close as practicable under the working surface, with a maximum fall height of 6m.

Regularly inspect nets for damage from UV radiation, abrasion, cuts, or chemical exposure. Damaged nets must not be used.

Ensure nets are supported by structures capable of withstanding the impact load from a falling person.
