Hazards Identification
· Health Hazard
TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Bromoacetates and chloroacetates are extremely irritating/lachrymators. Reaction with water or moist air will release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
· Fire Hazard
Flammable
· Explosion Hazard
Above 20°C explosive vapour/air mixtures may be formed
· Skin Hazard
Redness. Pain.
· Inhalation Hazard
Burning sensation. Cough. Shortness of breath. Sore throat. Symptoms may be delayed. See Notes.
· Eye Hazard
Redness. Pain. Loss of vision.
· Ingestion Hazard
Abdominal pain.
· Fire Potential
Corrosive and flammable liquid.
· Skin, Eye, and Respiratory Irritations
Methyl silicate can affect you when breathed in. Severely irritates and burns the eyes and skin. Exposure to the vapor can cause severe eye damage and cause permanent blindness. This can occur up to 12 hours after exposure has ceased, even if no irritation is noticed at the time. Inhalation irritates the respiratory tract. Higher exposures can cause pulmonary edema, a medical emergency, that can be delayed for several hours. This can cause death. Exposure to high levels can damage the lungs and kidneys.
Manufacturer of oxalic acid, diethyl oxalate and tetramethyl guadinine. With technical data.
Distributor of methyl mromide and amino acids for agricultural applications. At temperatures below 39ºC (102ºF), methyl isocyanate is a very flammable liquid that readily evaporates when exposed to air. Gaseous methyl isocyanate is approximately 1.4 times heavier than air. Methyl isocyanate liquid is colorless with a pungent odor. Manufacturer of cimetidine intermediates series, 4-methyl imidazole, pyruvaldehyde (methyl glyoxal), and pyruvate.
