Impetus for DfS

Can such risks posed to maintenance personnel be avoided?

Example of DfS in projects

• Save cost and time to erect scaffolding during maintenance

• Enhanced safety with no need to work at height• Effective long term maintenance

• Permanent maintenance unit

• Mitigate risk of being hit by passing vehicles

dImpetus to Mandate DfS

Shifting the WSH Intervention Upstream

“We cannot rely solely on downstream regulation and enforcement activities to achieve a

breakthrough in WSH performance. We have to do more upstream rather than only deal with the

risks that materialise downstream.

Presently, developers and designers tend to leave the identification of WSH risks in building

construction and maintenance to the builders and building operators. Performing RM upstream

would mean they have to make a conscious effort to collaborate with relevant experts toidentify WSH risks in their designs and incorporate the necessary risk control solutionsinto them upfront. Builders and facility operators will then have significantly fewer risks to

manage downstream.”

To achieve widespread adoption of DfS

and enable significant progress in

workplace safety, the Government has

decided to mandate DfS, and require

developers to ensure designs are safe to

build.

DEVELOPERS

� as far as it is reasonably practicable, ensure all

foreseeable design risks are eliminated

� if not reasonably practicable to eliminate, then ensurethat the design risk must be reduced to as low as reasonably practicable

6) DfS Register


“design risk” - anything that is provided or omitted in the design of a structure that increases the likelihood of a person being injured when constructing, working at or demolishing

the structure;

Example (ommission)

Part of the structure where maintenance need to be carried out have open sides and no barrier,

wall or guard-rail is designed for to prevent person from falling when it is reasonably practicable

to do so.

What is “Reasonably Practicable”?

• It means that the degree of risk in a particular situation can be balanced

against the time, trouble, cost and physical difficulty of taking measures to

avoid the risk.

• An action is considered to be practicable when it is capable of being done.

• Whether it is also reasonable usually takes into account:

– the severity of any injury or harm to health that may occur;

– the degree of risk (or likelihood) of that injury or harm occurring;

– how much is known about the hazard and the ways of eliminating, reducing or

controlling it;

– the availability, suitability and cost of the safeguards.
