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. Dangerous fire hazard in the form of dust when exposed to heat or flame.
Extinguishing Media: Use water spray, dry chemical, carbon dioxide, or chemical foam. 
Handling: Avoid breathing dust, vapor, mist, or gas. Avoid contact with skin and eyes. Use only in a chemical fume hood.
Storage: Store (R)-3-Isopropyl-2,5-piperazinedione (CAS NO.143673-66-9) in a cool, dry place. Store in a tightly closed container.
