Section3. Hazard Identification
Emergency Overview
Appearance: Clear yellow liquid
Flash point: 78 deg C
Warning! Combustible liquid and vapor. May cause central nervous system effects. May cause eye and skin irritation. May cause liver and kidney damage. Harmful if swallowed, inhaled, or absorbed through the skin. May cause blood abnormalities. Target Organs:
Blood, kidneys, central nervous system, liver, lungs.
Potential Health Effects
Eye: May cause eye irritation
Skin: May cause skin irritation. Harmful if absorbed through the skin.
Ingestion:Harmful if swallowed. May cause gastrointestinal irritation with nausea, vomiting and diarrhea. Methemoglobinemia is characterized by dizziness, drowsiness, headache, breath shortness, cyanosis with bluish skin, rapid heart rate and chocolate-brown colored blood. Effects may be delayed.
Inhalation: Harmful if inhaled. Effects may be delayed. May cause respiratory tract irritation. May cause methemoglobinemia, cyanosis, convulsions, tachycardia, dyspnea (labored breathing ), and death,
Chronic: May cause liver and kidney damage. May cause methemoglobinemia, which is characterized by chocolate-brown colored blood, headache, weakness, dizziness, breath shortness, cyanosis ( bluish skin due to deficient oxygenation of blood), rapid heart rate, unconsciousness and possible death. May cause anemia and other blood cell abnormalities. Prolonged or repeated exposure may cause nausea, dizziness, and headache. Effects may be delayed.
Section4. First Aid Measures
Eyes:
In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Get medical aid.
Skin:
In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid immediately. Wash clothing before reuse.
Ingestion:
If swallowed, do not induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. Get medical aid. Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to physician:
For methemoglobinemia, administer oxygen alone or with Methylene blue depending on the methemoglobinemia concentration in the blood.
Section5. Fire Fighting Measures
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. Use water spray to keep fire-exposed containers cool. Combustible Liquid. Vapors are heavier than air and may travel to a source of ignition and flash back. Vapors can spread along the ground and collect in low or confined areas. Extinguishing Media:
Water may be ineffective. For small fires, use dry chemical, carbon dioxide, or water spray. For large fires, use dry chemical, carbon dioxide, alcohol-resistant foam, or water spray. Cool containers with flooding quantities of water until well after fire is out.
Autoignition Temperature: 500 deg C (932 deg F)
Flash point: 78 deg C (172.4 deg F)
Explosion Limits: N/A
NFPA Rating: (estimated) Health: 2; Flammability: 2; Instability: 0
Section6. Accidental Release Measures
General Information:
Use proper personal protective equipment as indicated in Section8.
Spills/ Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Avoid runoff into storm sewers and ditches with lead to waterways. Clean up spills immediately, observing precautions in the protective equipment section. Remove all sources of ignition. Use a spark-proof tool. Provide ventilation.
Section7. Handling and Storage
Handling:
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Avoid contact with heat, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames. Use only with adequate ventilation. Storage:
Keep away from heat, sparks, and flames. Keep away from sources of ignition. Keep container closed when not in use. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Isolate from oxidizing materials and acids.
Section8. Exposure Controls/ Personal Protection
Engineering Controls:
Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits.
Personal Protective Equipments
Eyes:
Wear chemical goggles.
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 29CRF 1910.134 or European Standard EN149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.
