Shutters stop fire from spreading
IMM has automatic shutters - better known as the fire-rated shutters - that are activated to roll down in the event of a fire.
Ms Novia Yeo, marketing communications manager - IMM, CapitaMalls Asia, said the shutters are part of the Singapore Civil Defence Force (SCDF) requirement.
When asked about staff members guiding shoppers to safety after the shutters have rolled down, she declined to comment.
An SCDF spokesman said fire-rated shutters roll down when a fire alarm in the building goes off.
This is to create a segregation between two spaces so that the fire and the smoke can be prevented from spreading.
A metre-wide door is usually located at the side of the shutter, through which people can exit the area, and there are usually enough exits around the building to avoid people getting trapped.
