MANAGING SIGNIFICANT SPILLS [306-3] Being a leading chemical specialist, we are constantly dealing with huge amounts and various types of chemicals which pose a risk to the environment in the event of spillage. Potential contaminated areas and sources of spill can come from our warehouses, production lines and lab testing. In order to prevent any incidents of a spill and to minimise the negative impacts in the event of a spill, we have been setting multiple control measures in place and continuously improving these measures. Within CCM Polymers’ operations, we have implemented control measures and have specified how we can improve each mitigation step so that we have a fool- proof process as listed below. Current control Improvement Gate valve system at strategic location covering point of discharge into external drain. Improvement of chemical storage such as stacking system, bund wall and racking system. Bund wall near internal drain to control direct discharge during spillage. Enhance forklift driver competency through training and awareness to ensure spillage incident are minimised. Awareness to workers including forklift drivers on spillage prevention such as chemical transfer, loading and unloading of chemicals. • Evaluate chemical handling with high risk of spillage incident. • Evaluate existing HIRARC on each process. Spill kit for spillage emergency response. Evaluate operations’ processes which have potential spillage incident. Within CCM Chemicals’ operations, the risk of chemical spills or leaks may stem from our PGW and Shah Alam plants. The spill or leak could come from liquid products, fumes or chlorine gases. To this end, mitigation plans are in place at the design stage for the fabrication of all the relevant plants. At PGW, the emergency absorption tower and scrubber system are the two main features that will absorb any gas and fumes released via a pressure difference. These gasses and fumes are then treated by the same before being released into the atmosphere. There is also the risk of liquid products such as hydrochloric acid, caustic soda and nitric acid spilling out of their containers. As such, all storage tanks are located within a secured bund wall to contain any spillage. Should any spillage occur, the spillage is directed to the effluent treatment system. All online processes and operations are controlled and monitored via the Distributed Control System to enable operations personnel to identify and respond immediately to any unexpected events. | Our Commitment to Environmental Economic Practices | 42 CHEMICAL COMPANY OF MALAYSIA BERHAD
