Saraswathy said she had just entered the kitchen to prepare lunch when she heard a loud explosion that shook her two-storey corner lot house about 10am.
"I came into the living room to check and was shocked to see a huge truck there. I screamed and cried," said the former school teacher.
"I am lucky to be alive. If I had been watching television, I would have lost my life," said Saraswathy, who was still shaken over the incident.
Balakrishnan was also thankful that he had gone for a Rakan IJN Association meeting at the the National Heart Institute.
"If not for the meeting, I will be doing my daily routine of reading the newspaper in the living room," said Balakrishnan, who is the secretary of the association.
Balakrishan, City Hall’s former senior public health assistant, said he was unsure what to do now.
"My 35-year-old son stays with us. We have so many important things here and cannot leave the house," he said.
Alam Flora garbage truck driver R. Arumugam, 49, who witnessed the incident, said the truck may have developed brake failure.
"I had stopped at the traffic lights when I heard a loud screeching sound from behind and saw the truck coming fast from the Bangsar Shopping Centre direction.
"It avoided us by just a few metres and swerved into the road on our left before it rammed the house’s brick wall."
