WORK POSITIONING / SIT HARNESSES

HARNESSES (OR ADDITIONAL ATTACHMENTS ON A FULL BODY HARNESS)

INTENDED FOR USE WHERE FREE-FALL IS NOT USED – IN PARTICULAR, WORK POSITIONING / RESTRAINT AND FOR USE IN ABSEILING OR ROPE ACCESS.

Work positioning and sit / abseil harnesses, like full body harnesses, are subjected to a drop test to create a shock load on the harness. However, because the likelihood of a period of free-fall is greatly reduced in usage, a lesser force is given to the harness in proportion to the end use. Work positioning attachments are dropped 1 metre with a 1 metre length of rope, whereas sit harnesses are dropped over a 2-metre distance with a 1 metre length of rope. The harness is only required in both circumstances to effectively suppress the test dummy's descent after the drop.

Tensile testing is performed on the entire product. A 15kN tensile force is applied to belts, harnesses, and lanyards. To ensure that the product's breaking strength exceeds the force prescribed by the standard, tensile pressures are applied and held for at least 3 minutes.

A neutral salt-spray test is performed on metallic components used in fall prevention devices to demonstrate a minimum resistance to environmental corrosion (specifically rust). Products are kept in a sealed chamber that is filled with a salt-water mist that might cause rust on exposed metals. After 24- or 48-hours of exposure, the products are tested for corrosion and functionality.
