Safety Profile
Hazard Codes: 
Xi
Risk Statements: 36/37/38
R36/37/38: 2,3,6-Trichloroquinoxaline (CAS NO.2958-87-4) is irritating to eyes, respiratory system and skin.
Safety Statements: 37/39-26
S26: In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
S37/39: Wear suitable gloves and eye/face protection.
A poison by intravenous route. When heated to decomposition it emits toxic vapors of NOx and Cl−.
Specification
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.
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.
