iv. 
Permit-To-Work (PTW) system shall be put in place and strictly adhered to; 
and 
v. 
The risk assessment and SOPs shall be communicated to the WAH personnel 
prior to commencement of work and regularly while the work is ongoing. 
The evidence to show that WAH personnel have been briefed shall be made 
available on demand.  
2.4 Barricading Workspace 
The workspace which is the area where the WAH is taking place, shall be cordoned 
off or barricaded to prevent entry by unauthorized personnel. In addition, caution 
signs and other safety signs shall be placed around the workspace to alert personnel 
of the work activities taking place.     
2.5 Dropped Objects Prevention 
The management and prevention of dropped object hazards shall be in line with 
internationally recognised standards such as ANSI/ISEA 121-2018 standard or its 
equivalents. All tools used during WAH shall be secured to prevent injuries caused 
by tools falling on personnel working below the platform. At the minimum, the 
following shall apply: 
i. 
Tools shall be tethered using lanyards to anchorage points on the safety 
harness of the worker or on the structure. This should be the primary method 
to prevent dropped objects; 
ii. 
Secondary means such as perimeter netting, toe-boards etc shall be used to 
strengthen the dropped object prevention control; and 
iii. 
Where the tools are housed in a container/bucket/pouch, such housings shall 
be attached as in 3.5(i).  
Note: If the worker is the anchor point, the combined load of the tools shall not 
exceed 5lbs (2.3 kg).
