All but one line at subsidiary Chemrez, Inc.’s plant in Quezon City are running, D&L Industries, Inc. said on Friday in its latest update, following the facility’s closure due to escaping fumes.
D&L, in a disclosure to the Philippine Stock Exchange, said it had determined that the fumes – which spread last November 22 – were caused by “exothermic reaction during polymerization.”
“In particular, we were unable to inhibit polymerization with fresh styrene monomer shipment held up over the APEC holidays,” the firm said.
“As temperature and pressure increased in the tank, the relief valve was triggered, which released the fumes,” it added.
D&L said it was the first incident of this nature in the plant’s 31-year history.
The non-operating line is undergoing maintenance, it added. Preventive measures will be undertaken, including a failsafe chilling system, to prevent a repeat.
“The company’s facilities operate under strict conditions in compliance with standards and requirements of our customers, which are mostly multinational companies,” the firm claimed.
“Further, the Company implements an Integrated Management System (IMS) to ensure highest standards for product quality and care of customers, employees, and the environment.”
The suspension of operations at the plant is not expected to have material impact on sales of D&L, the firm said.
