IS 8769:1978 is the Indian Standard (BIS) for safety nets for construction work - specification. 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.
