1 PURPOSE
The purpose of this document is to ensure that chemicals are handled and stored safely in the work area,
and in compliance with national and international regulations, standards, and guidelines.
Safe chemical storage is an essential step in the safe management of hazardous chemicals. Proper storage
involves assessing, determining basic storage requirements, establishing optimum compatible groupings,
dating items with a shelf-life, and making routine assessments of chemicals in storage, removing
chemicals that are no longer needed. To define associated risks and controls for the hazardous materials
storage, handling, usage and disposal, which may cause temporary or permanent harm to health and
environment. This procedure has been developed to ensure proper effectiveness of the hazardous
materials storage at the SOCAR Polymer PP and HDPE plants.
2 SCOPE
This procedure applies to all hazardous chemicals stored at SOCAR Polymer and all Company employees,
including visitors and contractors, who work with hazardous chemicals.
