ACUTE EFFECTS
SKIN CONTACT: May cause skin and eye irritation. Absorption into the body may lead to formation of methemoglobin, which in sufficient concentration causes cyanosis. Possible delayed onset=2 to 4 hrs. Exposure can cause stomach pains, vomiting, diarrhea, nausea, dizziness and headache.
CHRONIC EFFECTS: Laboratory experiments have shown mutagenic effects. Target organ: blood.
4. FIRST AID
EYE CONTACT: Flush with copious amounts of water for 15 minutes while holding eyelids open.
SKIN CONTACT: Remove contaminated clothing. Wash with soap and copious amounts of water for 15 minutes.
INHALATION: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
