SECTION 2: Hazards identification

OSHA Clear, colorless, liquid with an ethereal odor.

Potential health effects

Dichlorofluoroethane SKIN: Repeated and/or prolonged exposure may cause irritation (defatting) of the skin. EYE: Irritant. Liquid will irritate and may cause conjunctivitis. INHALATION: Overexposure to vapor may cause dizziness, loss of concentration and irritation. With high exposure levels, effects can include central nervous system (CNS) depression (intoxication) and cardiac arrhythmia. Product vapors displace air and can cause suffocation especially in confined areas. INGESTION: Discomfort due to volatility would be expected. Some of the inhalation effects could be expected. Methanol INHALATION: Inhalation may cause irritation of the nose and throat with sneezing, sore throat or runny nose. SKIN: Skin contact may cause irritation with itching, burning, redness, swelling or rash. Skin permeation may occur in amounts capable of producing the effects of systemic toxicity. EYE: Eye contact may cause eye irritation with tearing, pain or blurred vision. INGESTION: Ingestion may cause irritation of the digestive tract with stomach pain, heartburn, nausea, vomiting, or diarrhea; however there may be no symptoms at all. INHALATION, INGESTION, OR SKIN: Temporary mild depression of the central nervous system with dizziness, confusion, incoordination or drowsiness followed by an asymptomatic period usually ranging from 12 to 24 hours. Metabolic acidosis develops followed by ocular toxicity (visual disturbance including blindness). Other effects include non-specific effects such as headache, nausea and weakness. Gross overexposure may cause pathological changes in the liver and kidneys; nerve damage with numbness, weakness or muscle rigidity; tremors; convulsions; and fatality. Increased susceptibility to the effects of Methanol may be observed in persons with pre-existing disease of the CNS, visual system, liver, kidneys and cardiovascular system. Nitromethane INHALATION Short-term overexposure may cause irritation of the nose and throat with sneezing, sore throat or runny nose. Based on animal data repeated and/or prolonged exposure may cause irritation of the nose, throat, and lungs with cough, difficulty breathing or shortness of breath, pathological changes in the liver, central nervous system depression with dizziness, confusion, incoordination, drowsiness or unconsciousness, peripheral nervous system effects with tingling, pain, or loss of sensation in extremities which may by accompanied by weakness or loss of muscle control, altered blood cell counts, impaired functioning of the blood-forming system with alterations in blood cell counts and/or anemia, effects on the nervous tissue, and clinical pathological changes of the thyroid. SKIN: May cause skin irritation with itching, burning, redness, swelling or rash. EYE: May cause eye irritation with tearing, pain or blurred vision. INGESTION: Based on animal data, may cause abnormal liver function with altered enzyme levels in blood, or abnormal kidney function with altered results on blood tests.
