Police: Finding out cause of Tradebe explosion in Bridgeport will take a few weeks

There is still no word on what caused a chemical explosion in Bridgeport.
State police say it is going to take weeks to have an answer.
The blast happened last Friday at a business called Tradebe on the East Side of town.
A total of three people were hurt during the incident.
City officials says they will form a committee to better inform residents about companies like Tradebe that operate in their neighborhoods since it was a chemical explosion at a hazardous waste management plant. 
The air was deemed safe, but officials still want people to hold off on fishing until results come in from water samples.
Initial reports from the fire department show there was a delivery of oxidizer, and it appears the driver opened a valve and that's when the explosion happened.
