Potential Health Effects
Eye: Contact may cause burns.
Skin: This product may be absorbed by the skin. May cause burns.
Ingestion: This product may cause severe gastroenteritis that can be fatal.
Harmful if swallowed.
Inhalation: This product may cause severe damage of mucous membranes
or upper respiratory tract. Harmful if inhaled.
Chronic: Exposure may lead to the formation of methemoglobin, which can
cause cyanosis. May cause argyria, burning sensations, coughing, wheezing,
laryngitis, headache, shortness of breath, nausea, or vomiting. Chronic inhalation
may lead to spasms, inflammation/edema of larynx and bronchi, chemical pneumonitis,
or pulmonary edema. This product is extremely harmful to tissue, mucous membranes,
upper respiratory tract, skin, and eyes.
Eyes: Immediately flush with running water for at least 15 minutes while holding eyes open. Check for and remove contact lenses. Seek medical attention. Skin: Flush with water for at least 15 minutes. Remove contaminated clothing and launder before reuse. Seek medical attention. Ingestion: If conscious, administer 2-4 glasses of water.
