What are the tasks involved?
Falling more than two metres. • Delivery and removal of formwork material. • Erecting falsework and timbers above two metres. • Laying out ply sheets to the top of joists. • Cutting in penetrations for columns/service risers. • Installation of walls and columns. • Stripping formwork and false work
What are the hazards and risks?
Material and/or person/s falling from truck (dogman/driver). Driver releasing straps from load. Workers falling during falsework and timber bearer and joist installations. Workers falling during ply sheet installation. Workers fall through column penetrations/service risers. Workers fall from height installing walls and columns.
Workers falling during formwork and falsework stripping.
What are the control measures?
Prior to releasing straps driver to ensure load has not shifted during transport. • Loads to be placed on pallets, stillage or pre slung prior to arriving on site. • Platform/ladder to be available to release straps caught on load. • False work and formwork will be installed by competent workers in accordance with manufactures design or engineered recommendations. • Where the is a potential to fall more than two metres, whilst erecting frames or timbers an intermediate work platform may be used that is at least 450 mm wide. • Intermediate working platforms for installation of falsework and timber bearer and joist will be a minimum of 450 mm wide. • Handrails (no less than 900 mm in height), mid rails and kick boards will be installed on formwork decks to prevent workers and objects falling. Handrails are to be robust construction and installed in accordance with the specific design. • Timber joist will be installed on top of bearers from below and be spaced at 400 mm centres. • Ply sheets will be laid progressively in front of the worker, and a minimum of 1800 mm will be maintained if no edge protection is in place. • Catch decks will be installed directly beneath column penetrations whilst being cut in. • All penetrations will be fully covered with ply mechanically fixed (screwed or nailed) and marked with ‘Penetration below’. • Intermediate working platforms for installation of walls and columns will have handrails (900–1000 mm) mid-rails and be a minimum of 450 mm wide. • False work and formwork will be dismantled by competent workers in accordance to the manufactures or engineered design. • Fall control measures for stripping will be as installation methods in reverse sequence.
