Dear Valued ASPRI Members,

Accident Notification: Worker fell through roof insulation


On 19 October 2018 around 3.30pm, a worker was working on the roof of a workshop under construction when he stepped onto the insulation layer and fell through it. The distance of fall to the ground was about 13.9 metres. Preliminary investigation shows that the worker’s safety harness was not anchored. The worker was pronounced dead at the scene by attending paramedics.
The Ministry of Manpower has commenced investigations into the accident.
Contractors and workers performing similar work activities are advised to take the necessary precautions and measures to protect themselves when working at heights. Workers must be informed of the possible hazards commonly encountered when working on roofs, such as fragile roof surfaces and unguarded openings. Risk assessment must contain site-specific safe work procedures for working on roofs e.g. installation of roof sheets. Workers must also be provided with and instructed on the proper use of the personal fall arrest system, including where to tie off (anchor) the fall protection equipment. Responsible persons must also ensure that workers maintain 100 percent tie-off (using a twin-tailed lanyard) to a horizontal lifeline or to secure anchorage points at all times while working at heights.

Accident Notification: Worker died and another injured at excavation worksite

On 20 October 2018 around 11.15am, two workers were assisting with the installation of shoring for an excavation when one of its walls collapsed, trapping both workers with soil up to their waists. Both workers were extricated and sent to hospital, where one of them subsequently passed away. The other worker was treated for minor injuries at the hospital.
The Ministry of Manpower has commenced investigations into the accident.
The industry is reminded to conduct a comprehensive and thorough risk assessment on all excavation work activities. Excavation wall collapse can be prevented through proper shoring. Shoring refers to the provision of supports to the sides of the excavation, to protect workers from being buried or trapped during excavation work. An appropriate and safe method for shoring installation must be determined during the work pre-planning phase based on soil classification and site conditions. A shield may also be placed between the sides of the excavation and the work area to prevent collapsing materials from falling onto workers. Supervisors must ensure that workers adhere strictly to the method statement for safe installation of shoring such that the integrity of the excavation will not be compromised during the installation process.
