This risk assessment document evaluates risks associated with edge protection during construction work. It identifies six key steps: 1) edge protection design and erection, 2) installing edge protection to leading edges, 3) installing hole protection to risers and penetrations, 4) installing protection to lift shafts, 5) dismantling edge protection, and 6) maintaining edge protection. For each step, potential hazards, consequences, initial risks, control measures, and residual risks are outlined. Control measures include fall protection equipment, inspection requirements, permitting systems, and ensuring only trained personnel undertake the work. The overall goal is to implement fall prevention measures and manage risks to protect workers during construction tasks involving heights.

i. Safety harness and lanyard are to be used by those installing protection
and hooked off to a secure anchor point behind them to restrictaccess to
open edge;
ii. No shock lanyard to be used on fall arrest below 6m in height;
iii. Edge protection to be between 900mm and 1150mm high,complete with
mid rails and kick boards on hand rails and securelyfitted to openings.
Where possible,rails shall protrude inside ofleading edges atleast
500mm to ensure full support;
iv. Edge protection shall never be made from scrap wood or other materials
not designed for the purpose,only proprietary materials and fittings;
v. Posts to be correctly anchored down with proprietary fittings of suitable
length,nails shall never be used for this purpose;
vi. All hand tools to be tied off when working at height;
vii. Correct manual lifting techniques ofmaterials communicated to workers;
viii. Signage in multi-language shall be fitted to edge protection,not paper
signs as this can easilybe damaged or fly off;
ix. Area below to be clear of workers during installation,barriers and
signage to be implemented below;
x. Edge protection to be inspected dailybefore work by designated
TemporaryWorks Co-ordinator or supervisor;
xi. Edge protection inspected after damage or incidentlikelyto affect
structural stabilitysuch as high winds,heavy rain or electrical storm;
