NFPA has published their much anticipated guide on Confined Spaces, NFPA 350: Best Practices Guide for Safe Confined Space Entry and Work, 2016 Edition. It became effective on December 4, 2015. This first edition of NFPA 350, Guide for Safe Confined Space Entry and Work, establishes best practices and “how to” for confined space entry and work, translating what is required in regulations into practical approaches to implement those requirements. Whereas existing regulatory standards provide minimum requirements, NFPA 350 strives to establish work practices that achieve a higher level of safety.
