The amount of overload used should bein line with the manufacturer’s recommendation.8.3.3.7 A drop test should be carried out at the safe working load on everysuspended working platform to test that the automatic safety devices arecapable of stopping and holding the load at the slope of the workingplatform specified by the manufacturer.8.3.3.8 Proof load test, overload device function test and operational test shouldbe conducted at or near ground or landing level. Before conducting thetests, a thorough examination should be carried out by the competentexaminer to ensure that no defective parts, malfunction of devices orloose components are present in the suspended working platform.8.3.3.9 After the proof load test, drop test, overload device function test andoperational test, the suspended working platform should be thoroughlyexamined by the competent examiner to ensure the safe working orderof the suspended working platform.
