Section 11 - Toxicological Information
ROUTE OF EXPOSURE
Skin Contact: Causes skin irritation.
Skin Absorption: May be harmful if absorbed through the skin.
Eye Contact: Causes eye irritation.
Inhalation: Material is irritating to mucous membranes and upper
respiratory tract. May be harmful if inhaled.
Ingestion: Harmful if swallowed.
TARGET ORGAN(S) OR SYSTEM(S)
Target organ: heart because methylene chloride is converted to
carbon monoxide in the body. Target organ: central nervous
system because of possible dizziness, headache, loss of
consciousness and death at high concentrations. Liver. Pancreas.
SIGNS AND SYMPTOMS OF EXPOSURE
Dichloromethane is metabolized in the body producing carbon
monoxide which increases and sustains carboxyhemoglobin levels
in the blood, reducing the oxygen-carrying capacity of the
blood. A simple asphyxiant, exposure can cause anesthetic
action, difficulty in breathing, headache, and dizziness.
Prolonged or repeated contact with skin can cause defatting and
dermatitis. Contact with eyes can cause redness, tearing, and
blurred vision. Ingestion may cause gastrointestinal irritation.
CNS depression. Paresthesia. Somnolence. Convulsions.
Conjunctivitis. Pulmonary edema. Effects may be delayed.
Irregular breathing. Ingestion can cause gastrointestinal
ALDRICH - 270563 www.sigma-aldrich.com Page 4
disorders, nausea, and vomiting. Increased liver enzymes.
Weakness. Heavy or prolonged skin exposure may result in the
absorption of harmful amounts of material. Drowsiness.
CONDITIONS AGGRAVATED BY EXPOSURE
Existing data suggests that methylene chloride may be a weak
mutagen in mammalian systems.
