Fire breaks out at NUS; 4 sent to hospital

A huge fire broke out at the National University of Singapore's Engineering Faculty this afternoon. 

A security guard working in the building was sent to the National University Hospital for smoke inhalation. 

The Singapore Civil Defence Force, or S-C-D-F, said three of its firefighters were also sent to NUH for heat exhaustion. 

No other injuries have been reported. 

As a safety precaution, all occupants in the building and the surrounding buildings were evacuated. 

The affected building and its surrounding areas have been cordoned off. 

NUS said smoke was first detected on the roof of Block E3A at the Kent Ridge Campus at 2.25pm. 

The SCDF deployed nine water jets to contain the fire. 

It said its firefighters had to break the windows on the first two floors for ventilation. 

It is believed that the incident happened at the solar energy research labs.

The University is investigating the incident.
