Some of the main causes were overturn,
falling/jumping off, collision with another
vehicle, struck by moving buggy.
Out of all these, falling/jumping off the buggy
was the most common cause of injury. Fatal cases

Accident Advisory: Worker fell from moving vehicle
1. Safe Vehicle
On 11 April 2018, a worker was travelling in a buggy cart within a park to get to her work
area. As the driver of the buggy cart drove along a bend, the worker fell off the buggy
cart and hit her head on the footpath. The injured worker was conveyed to the hospital
but subsequently succumbed to her injury.

Recommendations
Persons in control of similar workplaces and work activities such as occupiers and
employers are advised to consider the following risk control measures to prevent similar
accidents:
Safe vehicle
• Consider implementing speed limit for buggy cart operation using speed limiting
devices. Design the speed limiting device to be tamper-proof and accessible
only by authorised personnel.
• Provide seat belts for every seat in the buggy cart and perform regular checks
to ensure that they are fit for use. Seat belts should be worn by the driver and all
the passengers.
• Put up warning notices inside the buggy cart to alert passengers of the possible
dangers and the correct safety practice to be followed.
Safe driver
• Allow only trained and authorised personnel to drive a buggy cart.
• Insert into the safe work procedure that drivers are to carry out daily vehicle
inspection at the start of each work day before operating the buggy cart.
