Risk Statements about 1H-Pyrimidine, 2,3-dihydro-2,2-dimethyl-6-((4-(phenylazo)-1-naphthalenyl)azo)- (CAS NO.4197-25-5): R11 Highly flammable.
R36/37/38: Irritating to eyes, respiratory system and skin.
Safety Statements about 1H-Pyrimidine, 2,3-dihydro-2,2-dimethyl-6-((4-(phenylazo)-1-naphthalenyl)azo)- (CAS NO.4197-25-5): S16 Keep away from sources of ignition.
S26 In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
S24/25: Avoid contact with skin and eyes.
S37/39: Wear suitable gloves and eye/face protection.
Specification
1. Storage: Keep away from sources of ignition. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Keep containers tightly closed.
2. Handling: Wash thoroughly after handling. Use with adequate ventilation. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation.
3. Personal Protection: Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
4. Fire Fighting: Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Dusts at sufficient concentrations can form explosive mixtures with air. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Extinguishing media: Use agent most appropriate to extinguish fire. In case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam.
