04 · Handling and storage
Storing and handling Strontium Chromate
Storage conditions
Store in a secure poison location. ... Strontium chromate must be stored to avoid contact with strong oxidizers (such as chlorine, bromine, and fluorine), since violent reactions occur. A regulated, marked area should be established where this chemical is handled, used, or stored in compliance with OSHA Standard 1910.1045.
Source: Hazardous Substances Data Bank (HSDB)
Incompatible materials
Violent reaction with strong oxidizers, hydrazine. Incompatible with combustible, organic, or other readily oxidizable meterials, such as paper, wood, or other aluminum powder. Attacks plastics and coatings.
