It is recommended that a graded approach be used in meeting this requirement.

Restrictions and requirements for welding and cutting activities at locations where chemicals are used and stored

are based on specific conditions. Consult your local facility welding and cutting program to determine what

requirements are applicable to specific activities and conditions at your site.

This requirement is intended to keep chemicals safe during routine storage and during an upset condition such as a

fire. Therefore, chemicals that are only incompatible at elevated temperatures are still considered incompatible

during routine storage conditions due to the possibility of fire or other upset condition. This document does not
