1,2-BUTANEDIOL Specification

1、Fire Fighting Measures of 1,2-BUTANEDIOL
General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. 
Extinguishing Media: In case of fire, use water, dry chemical, chemical foam, or alcohol-resistant foam. 
2、Handling and Storage of 1,2-BUTANEDIOL 
Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Avoid contact with eyes, skin, and clothing. Avoid ingestion and inhalation. 
Storage: Store in a cool, dry place. Keep container closed when not in use.
