A Singaporean worker at an SP Group worksite in Kranji Loop died yesterday after he was injured while carrying out cable works.

The Singapore Civil Defence Force said it received a call at around 11.30am about the incident, and the worker was subsequently taken to hospital.

The Straits Times understands that he died in hospital later in the day.

In a media statement last night, electricity grid operator SP Group said the worker was injured while carrying out cable jointing at the worksite.

Cable jointing is the joining of cables to each other.

"We are saddened that the worker died and extend our deepest condolences to his family," SP Group said. "The Singaporean worker was a sub-contractor of James Contractor - the construction company that SP Group appointed to carry out cable works there. We are working closely with James Contractor to assist the family of the worker."

SP Group has halted work at the site and is investigating the cause of the incident.

The incident comes even as the number of workplace injuries and deaths has fallen.

In the first half of this year, there were 6,151 workplace injuries, of which 19 were fatal, figures from the Ministry of Manpower and Workplace Safety and Health Institute show.

Seven, or more than one-third, of the 19 deaths took place in manufacturing (five deaths) and construction (two deaths).

The top two causes of workplace death in Singapore were accidents involving vehicles on public roads or at worksites, and falls from height.

In contrast, there were 6,245 injuries in the first half of last year, 42 of which were fatal.
