| Hazards Identification | Back to Contents | 【Inhalation】
May cause respiratory tract irritation. Methemoglobinemia is characterized by dizziness, drowsiness, headache, breath shortness, cyanosis with bluish skin, rapid heart rate and chocolate-brown blood. This product contains nitrite which may cause methemoglobinemia. | 【Skin】
Causes skin irritation. | 【Eyes】
Causes eye irritation. | 【Ingestion】
Harmful if swallowed. Causes gastrointestinal irritation with nausea, vomiting and diarrhea. May cause methemoglobinemia, cyanosis, convulsions, and death. Methemoglobinemia is characterized by dizziness, drowsiness, headache, breath shortness, cyanosis with bluish skin, rapid heart rate and chocolate-brown colored blood. May cause allergic reaction. | 【Hazards】

| Exposure Controls/Personal Protection | Back to Contents | 【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. | 【Respirators】
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary. | 【Exposure Effects】
Respiratory depression secondary to hypoxia may occur. CNS depression is secondary to hypoxia from methemoglobinemia. DNT was NOT teratogenic in rats, and had no effects in a 3- generation study in rats. Testicular effects have been seen in laboratory animals, but not in exposed workers. | 【Exposure limit(s)】
TLV: ppm; 1.5 mg/m3 (as TWA) (skin) (ACGIH 1996). |
| Fire Fighting Measures | Back to Contents | 【Flash Point】
131 | 【Fire Fighting】
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. To extinguish fire, use water fog, dry chemical, carbon dioxide, or regular foam. | 【Upper exp. limit】
8.2 | 【Lower exp. limit】
1.4 | 【Fire Potential】
Dinitrotoluenes may burn but do not ignite readily. Combustible: moderate fire hazard. |
