Building owners, designers and persons in control of similar workplaces and work activities such as occupiers and employers are advised to mitigate all WSH hazards and implement risk control measures to prevent similar accidents:
• Conduct thorough inspections to all areas to identify WSH hazards and assess
WSH risks. WSH hazards include risk of falling from or falling through fragile
surfaces. These risks are further aggravated if proper guard rails are not installed
or there is inadequate lighting.
• Communicate the hazards and risks to contractors who will carry out maintenance
work within the restricted/enclosed/concealed areas. Communication should be
thorough and location-specific.
• Implement control measures to address all hazards identified, with consideration
of prevailing regulations, standards and acceptable code of practices.
– Provision of perimeter guard-railing or guard rail with intermediate guard rail
Note: The above requirements have been stipulated in regulation 9 of the Workplace Safety and Health (Work at Heights) Regulations 2013 and ACOP SS 567:2011 – Code of Practice for Factory Layout – Safety, Health and Welfare Consideration. For reference of temporary edge protection, refer to SS EN 13374.
| – If there are areas of fragile surface, warning signs must be displayed at all
access points and on the guard rails at suitable intervals to warn persons
from accidentally stepping onto them.
| – For poorly lit areas, additional permanent lightings must be provided so
that hazard(s) can be easily identified along with their corresponding risk
• Conduct site-specific risk assessment to the work area for any safety lapses and
ensure that precautions have been taken before commencing work.
• Provide standing supervision when carrying out works near false ceiling or
• Brief workers on on-site hazards, risk controls that are in place and the
necessary precautions to take while at work, including proper use of equipment
and materials for the work.
• Ensure that workers have undergone and passed the relevant training for work
where there is a risk of falling.
• When designing access walkway, services (e.g. Mechanical and Electrical) or
supporting structures (e.g. trusses) for restricted or enclosed areas, always
pay attention to provision for safe access and egress, adequate lighting and
provision of fall protection to future work to be carried out in these areas, such
as maintenance work by building contractors, inspection work by Qualified
Persons or installation of telecommunication devices by specialist contractors.
As a good practice, designers should engage with downstream stakeholders
(e.g. Facilities Management practitioners and contractors) to appreciate the
way maintenance would be undertaken and account for this at planning and
• The WSH (Design for Safety) Regulation stipulated that during the design of a
building, regardless of whether it is a new-build construction or an Addition and
Alteration project, developers / building owners and designers must always
remember that their design decisions can affect the health and safety of workers
and others who construct, maintain, repair, clean, refurbish and eventually
demolish or remove the building or structure. Taking into account risks arising
from the design can have a positive impact on the project and make it easier for
these risks to be managed by contractors who construct and those who maintain
• The WSH Guidelines on Design for Safety helps designers to understand and be
aware of significant risks that workers can be exposed to, and how these can
arise from their design decisions. Through a maintenance strategy report,
designers must capture and provide their clients with health and safety
information that might affect them or downstream stakeholders during and
after construction, for example, details on how to clean, access or maintain
parts of their design.
