First Aid Measures

Ingestion
Get medical aid immediately. Wash mouth out with water.
Inhalation
Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Skin
Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
Eyes
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.

Handling and Storage

Storage
Keep away from sources of ignition. Store in a cool, dry place. Store in a tightly closed container.
Handling
Do not breathe dust, vapor, mist, or gas. Do not get in eyes, on skin, or on clothing. Use only in a chemical fume hood.

Hazards Identification

Inhalation
Toxic if inhaled.
Skin
Causes moderate skin irritation. Absorption into the body may cause cyanosis. Toxic in contact with skin.
Eyes
Causes moderate eye irritation.
Ingestion
Poison by ingestion.
Hazards
When heated to decomposition, it emits toxic fumes of nitrogen oxides. Avoid decomposing heat.

Exposure Controls/Personal Protection

Personal Protection
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
May cause methemoglobinemia, which is characterized by chocolate-brown colored blood, headache, weakness, dizziness, breath shortness, cyanosis, rapid heart rate, unconsciousness and possible death. Absorption into the body leads to the formation of methemoglobin which in sufficient concentrations causes cyanosis.

Fire Fighting Measures

Flash Point
96
Fire Fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Will burn if involved in a fire. To extinguish fire use water spray, dry chemical, carbon dioxide, or chemical foam.

Accidental Release Measures

Small spills/leaks
Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container.
