Carbon monoxide is a product of incomplete combustion of organic matter due to insufficient oxygen supply. Signs & Symptoms include light headedness, confusion, headaches, vertigo, and flu-like effects; larger exposures can lead to significant toxicity of the central nervous system and cardiovascular system and death. Carbon monoxide can also have severe adverse effects on the foetus of a pregnant woman. Hydrogen Chloride is a colourless to slightly, yellow gas with an irritating, pungent odour (product of burning PVC).Hydrogen chloride is irritating and corrosive to the eyes, skin, airways and mucous membranes. Signs & Symptoms include constant coughing, breathing difficulties and stress. Exposure to high concentrations can cause laryngitis, bronchitis, and pulmonary oedema.Hydrogen Cyanide (the gaseous form of cyanide), is generated by the combustion of nitrogen and carbon-containing substances, including wool, silk, cotton and paper, as well as synthetic substances, such as plastics and other polymers. Signs & Symptoms include faintness, flushing, anxiety, excitement, perspiration, vertigo, headache, drowsiness, breathing difficulties, tachycardia, convulsions. Burns and Scalds 125'
