Safe Use of Harnesses : Safe Use of Harnesses Fit – Harnesses have maximum weight allowance Are operatives wearing them correctly What can they anchor too? Need secure anchor point Choking – bad practice Lanyard Type – Traditionally sold with fall arrest lanyard Have operatives enough room to fall? Can they be rescued? Slide 13: ScaffoldingGeneral Requirements Must be capable of supporting four times the maximum intended load Do not alter or move while in use Protect workers on scaffolds from overhead hazards If higher than 10 ft., use guardrails, mid rails and toe boards Use wire mesh between the toe board and guardrail if people work or pass underneath Must be equipped with access ladder or equivalent Slide 16: All excavations deeper than 1.25meters MUST be shored or battered.
