EMERGENCY OVERVIEW
Appearance: Dark greenish-purple
Caution! May cause eye and skin irritation. May be absorbed through the skin.
Target Organs: None known.
Potential Health Effects
Eye:
May cause eye irritation.
Material Safety Data Sheet
Methyl purple indicator solution
Skin:
May cause mild skin irritation. May be absorbed through the skin. If absorbed, may cause central nervous system
depression.
Ingestion:
Abdominal pain, nausea, vomiting, hemorrhage; central nervous system depressant, may lead to coma and death from
respiratory paralysis.
Inhalation:
Central nervous system depression, respiratory irritation, dizziness, nausea, vomiting, headache, incoordination,
refractory narcosis, areflexia, flushing; severe exposure may result in coma, death from respiratory arrest.
Chronic:
Dermatitis, conjunctivitis with corneal damage may occur.
Section 4 - First Aid Measures
Eyes:
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower lids until no evidence
of chemical remains. Get medical aid at once.
Skin:
Get medical aid. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing
contaminated clothing and shoes. Remove contaminated clothing and shoes.
Ingestion:
Get medical aid at once. Give oxygen if respiration is depressed. Induce vomiting (touch finger to back of throat)
keeping head lower than hips (prevent aspiration into lungs).
Inhalation:
Give artificial respiration if necessary. Get medical aid. Keep victim warm, at rest. Move victim to fresh air.
Notes to Physician:
Treat symptomatically and supportively.
Section 5 - Fire Fighting Measures
General Information:
Negligible fire and explosion hazard when exposed to heat or flame. Avoid breathing vapors, use approved respirator if
necessary. Vapors heavier than air, may travel considerable distance and flash back from source of ignition. Move
container if possible, avoid breathing vapors or dust.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or alcohol-resistant foam.
Autoignition Temperature:
N/A
