Section 3 - Hazards Identification

Appearance: dark brown solid.
Danger! May be fatal if absorbed through the skin or swallowed. Causes eye burns. Causes skin irritation and possible burns. Harmful if inhaled. Causes respiratory tract irritation. May cause allergic skin reaction. May cause central nervous system effects. Light sensitive.
Target Organs: Central nervous system, respiratory system, eyes, skin.


Potential Health Effects
Eye: Causes eye burns.
Skin: Harmful if absorbed through the skin. May cause skin sensitization, an allergic reaction, which becomes evident upon re-exposure to this material. May cause blistering of the skin. Causes skin irritation and possible burns. Substance is readily absorbed through the skin. Life-threatening toxicity may result from adult skin exposure to very minute quantities (1 teaspoon), based on animal studies.
Ingestion: May be fatal if swallowed. Methemoglobinemia is characterized by dizziness, drowsiness, headache, shortness of breath, cyanosis (bluish discoloration of skin due to deficient oxygenation of the blood), rapid heart rate and chocolate-brown colored blood. May cause tremors and convulsions. May form methemoglobin which in sufficient concentration causes cyanosis (bluish discoloration of skin due to deficient oxygenation of the blood).
Inhalation: Dust is irritating to the respiratory tract. Harmful if inhaled. Inhalation of high concentrations of vapors has produced toxicity and death in experimental animals.
Chronic: Absorption into the body leads to the formation of methemoglobin which in sufficient concentrations causes cyanosis (bluish discoloration of skin due to deficient oxygenation of the blood). Laboratory experiments have resulted in mutagenic effects. Prolonged skin exposure may cause allergic dermatitis and possible hemorrhage.

Section 4 - First Aid Measures

Eyes: In case of contact, immediately flush eyes with plenty of water for a t least 15 minutes. Get medical aid immediately.
Skin: POISON material. In case of contact, get medical aid immediately. Immediately flush eyes or skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Destroy contaminated shoes.
Ingestion: POISON material. If swallowed, get medical aid immediately. Only induce vomiting if directed to do so by medical personnel. Never give anything by mouth to an unconscious person.
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: Treat symptomatically and supportively.

Section 5 - 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. This material in sufficient quantity and reduced particle size is capable of creating a dust explosion.
Extinguishing Media: Use carbon dioxide, water spray, or dry chemical.

Section 6 - Accidental Release Measures

General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks: Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, observing precautions in the Protective Equipment section. Avoid generating dusty conditions. Provide ventilation.

Section 7 - Handling and Storage

Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Minimize dust generation and accumulation. Do not breathe dust, mist, or vapor. Do not get in eyes, on skin, or on clothing. Keep container tightly closed. Do not ingest or inhale. Use only with adequate ventilation.
Storage: Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Store protected from light.

Section 8 - Exposure Controls, Personal Protection

Engineering Controls: Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use only under a chemical fume hood.

Section 12 - Ecological Information

Ecotoxicity: Bacteria: Phytobacterium phosphoreum: EC50 = 0.84-2.16 mg/L; 5,15,30 min; Microtox test at 15C If released to water, covalent bonding with humic materials in the water column and sediments may result in significant partitioning from the water column. N-N-dimethyl-p-phenylenediamine in the water column may be susceptible to significant photooxidation via hydroxyl and peroxy radicals and singlet molecular oxygen. Direct photolysis may also contribute to aquatic degradation. The lack of data makes statements regarding the degradation of N,N-dimethyl-p-benzenediamine impractical.
Environmental: If released to the atmosphere, N-N-dimethyl-p-phenylenediamine will degrade rapidly (estimated half-life of 1.368 hours) by reaction with photochemically produced hydroxyl radicals. If released to soil, N-N-dimethyl-p-phenylenediamine may be susceptible to high amounts of leaching in soil based on an estimated Koc range of 10.8 to 19.1. However, N-N-dimethyl-p-phenylenediamine may undergo a covalent chemical bonding with humic materials which can result in its chemical alteration to a latent form and prevent leaching. Readily biodegradable.
Physical: No information available.
Other: No information available.
