Facilities often face uncertainty when working with plastics, particularly when determining whether explosion protection is necessary. While some materials are clearly combustible, others are not, and many exhibit unpredictable behaviors based on factors such as particle size, processing methods, or the presence of additives. To complicate matters further, NFPA and ATEX standards provide limited guidance on how plastics should be evaluated, leaving many facilities uncertain about whether to implement zoning, protection measures or additional testing. In this session, we will address:
● The reasons behind the inconsistent behavior of plastics and the factors that influence ignition characteristics
● How to interpret lab test results that are borderline or conflicting
● The limitations of current ATEX and NFPA guidelines
● Strategies for determining zoning and protection measures when data is inconclusive
