Fire tenders from Couva and Wrightson Road responded and confined the blaze to the top floor.
Acting Chief Fire Officer Roosevelt Bruce said they were alerted around 3:15pm and upon arrival, they had a water supply challenge.
"Initially we had issues with water. The hydrant wasn't supplying enough water. WASA boosted the pressure in the area and we had a slight assistance there. However, we called for tankers. We have tankers now from Water and Sewerage Authority, we have tankers from the Central Regional Corporation and that has helped us a great deal."
Initial reports said the fire started in the kitchen but employee Kara Jagan believes it started somewhere in the warehouse section.
"We take our bags and we come down the stairs because the roof already started to fall and we just run down the escalator and came out fast."
Some 40 plus employees were said to be on the compound at the time of the fire which occurred around the time for the changing of shifts.
