Proc 8047 Inhib Methanol Add

SECTION 2: Hazards identification

EMERGENCY OVERVIEW: Poison. May be fatal or cause blindness if swallowed. Causes severe skin and eye irritation. Vapours, mists or sprays are extremely irritating to eyes and respiratory tract. High vapour concentrations may cause drowsiness. May cause teratogenic/embryotoxic effects based on studies in laboratory animals. See "Other Health Effects" Section. Flammable liquid and vapour. May cause flash fire or explosion. Can decompose at high temperatures forming toxic gases. Contents may develop pressure on prolonged exposure to heat.

Potential health effects

Inhalation: Toxic! Contact with mist or spray may cause irritation of mucous membranes, coughing and difficulty in breathing. See "Other Health Effects" Section. Skin Contact: Toxic! Prolonged and repeated contact may lead to dermatitis. May cause defatting, drying and cracking of the skin. Skin contact can cause irritation, especially under the finger nails (and other confined spaces such as under rings or watch bands). Skin Absorption: May be absorbed through intact skin. Toxic by way of skin contact. Eye Contact: Splashes to the eye may cause irritation, redness and pain. Ingestion: This product causes irritation, a burning sensation of the mouth and throat and abdominal pain. This substance is toxic if swallowed. Ingestion is not a likely route of exposure.

Other Health Effects

May cause central nervous system (CNS) depression, pulmonary edema, visual disturbances, glaucopsia, blindness, photophobia, kidney damage, liver damage, metabolic acidosis, systemic poisoning or death. CNS depression is characterized by headache, dizziness, drowsiness, nausea, vomiting and incoordination. Severe overexposures may lead to coma and possible death due to respiratory failure. Pulmonary edema is the build-up of fluid in the lungs that might be fatal. Symptoms of pulmonary edema, such as shortness of breath, may not appear until several hours after exposure and are aggravated by physical exertion. (4) Methanol: Mild blurring of vision to complete blindness may occur, including changes in colour perception and photophobia. Symptoms usually develop 12-18 hours after exposure. Metabolic acidosis is a condition that describes a decreased pH and bicarbonate concentration in the body fluids. Abnormal sensitivity to light is termed photophobia. Liver damage is characterized by the loss of appetite, jaundice (yellowish skin colour), and occasional pain in the upper left-hand side of the abdomen. Signs and symptoms of kidney damage generally progress from oliguria, to blood in the urine, to total renal failure. Monoethanolamine: Exposure to the vapour may cause minor transient oedema of the corneal epithelium. This condition, referred to as glaucopsia, "blue haze", or "blue-gray haze" produces a blurring of vision against a general bluish haze and the appearance of halos around bright objects. The effect disappears spontaneously within a few hours of the end of an exposure, and leaves no permanent damage. Although not detrimental to the eye per se, glaucopsia predisposes an affected individual to physical accidents and reduces the ability to undertake skilled tasks such as driving a motorized vehicle.
