NFPA NFPA 42 Handbook 2002 Free Download: Storage of Pyroxylin Plastic

Let's delve into the key differences between the current version of NFPA 42 (Code for the Storage of Pyroxylin Plastic) and the previous version (from 2002): Scope and Purpose: Current Version: NFPA 42 continues to provide requirements for the safe storage of pyroxylin plastic in storage buildings and manufacturing plants. Previous Version (2002): The 2002 edition had a similar scope but did not cover cellulose nitrate flat or motion picture film. Definition of Pyroxylin Plastic: Current Version: Defines pyroxylin plastic as any plastic substance, material, or compound (other than cellulose nitrate film) that has soluble cotton or similar cellulose nitrate as a base. This includes blocks, slabs, sheets, tubes, or fabricated shapes. Previous Version (2002): Likely had a similar definition, but specific details may have varied. Updates and Revisions: Current Version: Reflects any changes, advancements, or clarifications made since 2002. Previous Version (2002): May not have incorporated the latest industry knowledge or addressed emerging concerns. Withdrawal: Current Version: Remains in effect. Previous Version (2002): Was withdrawn at the Annual 2008 meeting. In summary, the current NFPA 42 maintains its focus on pyroxylin plastic safety, while the 2002 version lacked coverage of certain materials and may not have been as up-to-date.
