The first three sections of this Health and Safety Guide present essential technical information and the hazard evaluation. Section 4 includes advice on preventive and protective measures and emergency action; health workers ...

Trichlorfon is a colourless crystalline powder that is stable at room temperature. It is slowly hydrolysed in acid media; the half-life is 526 days at pH 1-5 and 20°C. In alkaline media, at pH 8 and 37.5 °C, it hydrolyses ...

Nickel is a naturally occurring, shiny, light-coloured metal with high electrical and thermal conductivities. It is resistant to corrosion by air, water, and alkalis, but reacts with dilute oxidizing agents.

Aldicarb has a slight sulfur smell. It has a melting point of 100 °C and a specific gravity of 1.195 at 25 °C. it is soluble in water, sensitive to heat, and relatively unstable. Analytical methods for aldicarb include ...

Hydroquinone is a white crystalline substance when pure and is highly soluble in water. Hydroquinone is combustible when preheated. It is a reducing agent that is reversibly oxidized to semiquinone and quinone.

Carbon tetrachioride is a volatile, colourless, clear, heavy liquid with a characteristic sweet, non-irritant odour. The odour threshold in water is 0.52 mg/litre, and in air it is >64.1 mg/m3 (10 ppm). Carbon tetrachioride ...

Trimellitic anhydride is a white solid in the firm of flakes. It is readily hydrolysed in water to trimellitic acid, which is moderately soluble in water. Trimellitic anhydride is readily soluble in acetone, cyclohexanone, ...

Anhydrous hydrazine, and aqueous solutions, are colourless liquids. Anhydrous hydrazine is a caustic, fuming, hygroscopic liquid at normal temperature and pressure. It has an ammoniacal, fishy, and pungent odour. The odour ...

Methanol is a colourless, polar, volatile, flammable liquid with a mild alcoholic odour when pure. It decomposes on heating producing carbon monoxide and formaldehyde. Methanol reacts violently with oxidizing materials ...

At ambient temperature, HCB is a white crystalline solid. Technical grade HCB is available as a wettable powder, liquid or dust. It is virtually insoluble in water, but is soluble in ether, benzene, chloroform and hot ...
