SINGAPORE: A misting machine, in-built storage ponds and weather monitoring devices – these are some measures a construction firm in Singapore is taking to protect their workers from the elements. 

The misting system helps to cool the worksite, providing some relief to those toiling under the sun. The ponds hold rainwater to prevent flooding, before the water is treated to remove silt and released into public drains.

Both measures are used in tandem with devices that track changes in weather. These gadgets give early warnings of strong winds and thunderstorms – conditions that are particularly dangerous for those working at height.

“I always reminded my fellow workers … that safety is not just a priority for a company, but it is a core value for us and we expect the same from our partners,” said Mr Qian Liangzhong, chairman of China Construction (South Pacific) Development Co Pte Ltd.

GUIDELINES TO BE RELEASED SOON

Such companies often affected by extreme weather conditions will soon be able to rely on a set of workplace safety and health guidelines, which are being developed by the Ministry of Manpower (MOM) and the Workplace Safety and Health (WSH) Council.

A ministry spokesperson told CNA that they will finalise and release the guidelines after consultations with the industry and public. It did not specify a timeline.

This comes about three weeks after MOM and the WSH Council advised companies to prepare for erratic and sudden changes in weather conditions. 

The country had recently been hit by strong winds and heavy rain that toppled trees, snarled traffic and caused damage to property.

“With climate change, Singapore can expect unexpected weather conditions that would impact workplace safety and health,” said the MOM spokesperson.

“Hence, the guidelines aim to raise awareness on the likelihood of an extreme weather event and its consequences on workplaces.”

Companies will be able to seek guidance on how to prepare and respond to such events, as well as how to minimise injuries and property damage.

Experts told CNA that a high level of preparation is necessary, given how Singapore and its surrounding region have become prone to more frequent episodes of extreme weather.

Assistant Professor Gianmarco Mengaldo from the National University of Singapore’s College of Design and Engineering was among researchers who recently published a study on new or emerging patterns in the tropical Indo-Pacific.

Using historical data from the 1940s until present day, they identified that these patterns are due to long-term trends over the past 80 years.

“These emerging patterns are actually aggravating the frequency of extreme weather events, in particular heatwaves and extreme rainfall in this region,” said Dr Mengaldo, who is also director of the Mathematical and Computational Engineering Laboratory.

“Some possible culprits of these newer patterns that are driving more extreme weather events are global warming, possibly aerosol forcing, among others.” 

Aerosol forcing refers to the contributions aerosol particles – the seeds on which clouds form – make towards the heating and cooling of the earth, including the scattering and absorption of sunlight and the distribution of clouds.
