Mr Chandy said that an emergency cabinet meeting will be held at Kollam on Sunday afternoon to decide on how to go about the investigation into the tragedy and related matters.
The chief minister tweeted that he had asked the chief secretary to write to the Election Commission seeking permission to help the victims as it is election time in the state.
Rahul Gandhi spoke to Mr Chandy and expressed grief over the tragedy.
Kerala's Home Minister Ramesh Chennithala told reporters at the accident site that the government is focussed on ensuring that all necessary help is provided to the victims who are suffering.
"On things like whether necessary permissions were obtained for the firework display and such issues will be dealt with when the cabinet meets later in the day at Kollam. Now our priority is to see all help is provided to the grieving," said Mr Chennithala.
The incident occurred a while after 3am on Sunday.
"I was watching the event unfold about 150 metres from the terrace of my friend's home. The firework display was about half an hour to finish when a spark of an already lit cracker landed in the concrete building that stored the high potency crackers. In few minutes, the building came crashing down and we felt the place shaking," said Pillai.
"Then it was absolute chaos and pieces of concrete were scattered all over the place and some of it were found about 500 metres away in a taxi stand," Pillai added.
Numerous homes within half a kilometre radius of the accident site have been damaged.
Thiruvananthapuram Medical College principal Thomas Mathew said about 100 people are being treated at the hospital.
"Forty five of them have been admitted and most of them are being treated for broken bones in their hands and legs. Eleven of them were brought dead, while another two died after reaching here," said Mr Mathew.
All the leading political parties have as a mark of respect cancelled all their election programmes for the day.
"We have asked our party workers to see that they provide all the help and solace to the victims," CPI-M state secretary Kodiyeri Balakrishnan told reporters after visiting the injured in the hospital in the capital city.
The BJP has cancelled all the programme of its national president Amit Shah, who was to launch his party's election campaign on Sunday at Pathanamthitta and is reaching the state capital to visit the injured.
The state Congress party president VM Sudheeran has asked his party workers to call off all election related work planned for Sunday.
