First Aid Measures

Ingestion
If victim is conscious and alert, give 2-4 cupfuls of milk or water. Get medical aid immediately. Induce vomiting by giving one teaspoon of Syrup of Ipecac.
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
Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if symptoms occur.
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
Poison room locked.
Handling
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Avoid contact with skin and eyes. Do not ingest or inhale.

Hazards Identification

Inhalation
May cause respiratory tract irritation. May cause effects similar to those described for ingestion.
Skin
Causes skin irritation. May be absorbed through the skin in harmful amounts. Produces acneiform eruptions.
Eyes
Causes eye irritation.
Ingestion
May cause irritation of the digestive tract. 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 skin eruptions and/or acne.
Hazards
Containers may explode when heated.
