when not to use ladder
where 2 hands needed for task where equipment / materials are large excessive height long duration ladder cannot be secured cannot be protected from vehicles adverse weather
ladder safety
pre-use check safe position firm level base 75 degree angle (1 out 4 up) tied / footed use both hands to grip when ascend / descend don't overload only one person at a time use toolbag / holster don't over reach
trestles
use where scaffold impracticable low level edge protection firm level surface trestle every 1.5 metres do not exceed SWL
erection / dismantling scaffolding
competent persons
minimise risk of items falling
intermediate platform with guard rails / toeboards before build next level
scaffold inspections
before first use
after alteration
after event likely to affect stability
regularly not exceeding 7 days
falsework
temp structure to support permanent structure
risk assess & SSW
inspect & certify for use
periodic inspection
factors ref falling materials
poor housekeeping no toeboards / edge protection incorrect slinging incorrect stacking gaps in platforms
roof work controls
edge protection
safety harnesses and lanyards
marked areas where not possible to fall from
safety nets for leading edges where roof materials laid / removed
staging platforms
access cradles
installed by competent persons thorough exam report safe area fenced off not used in poor weather trained users switch off and make dead at end of use secure so not accessible to others
boatswains chairs
light short duration work rigid seat person hoisted or lowered use where cannot provide practicable platform install by competent person pre-use check test / exam certs safe area below secure after use to prevent swinging dry off ropes
rope access
