Identification and classification of chemicals<\/h3>\n\n\n\n

Identification of chemicals begin with knowledge of basic chemistry.<\/p>\n\n\n\n

Chemicals are classified in different ways.<\/strong><\/p>\n\n\n\n

They are broadly classified as organic and inorganic chemicals.<\/p>\n\n\n\n

In organic are sub classified as metal and non metal.<\/p>\n\n\n\n

Out of 104 elements, 80 are metals and majority of them are solid.<\/p>\n\n\n\n

In non metal, more than half are gases.<\/p>\n\n\n\n

Metals: aluminium, arsenic, calcium, chromium, cobalt etc.<\/p>\n\n\n\n

Non metals: bromine, chlorine, flourine, iodine etc.<\/p>\n\n\n\n

Organic chemicals include carbon compound.<\/p>\n\n\n\n

They are sub classified as<\/strong>;<\/p>\n\n\n\n

Aliphatic compound (without benzene rings): hydrocarbon, alcohol , ethers, ketons, aldehydes etc.<\/p>\n\n\n\n

Aromatic: benzene, phenol, aromatic alcohol etc.<\/p>\n\n\n\n

Heterocyclic compound and polymers (with other compound): furan, pyridine, thiophene etc.<\/p>\n\n\n\n

Chemicals are also classified as under;<\/strong><\/p>\n\n\n\n

    \n
  1. According to physical state: solid, liquid or gas <\/li>\n<\/ol>\n\n\n\n

    2. Noxious gas:<\/p>\n\n\n\n

    Irritant gas: chlorine, ammonia, SO2<\/p>\n\n\n\n

    Systemic poison: benzene, nickel carbonyl etc.<\/p>\n\n\n\n

    Simple asphyxiate: nitrogen, methane, CO2<\/p>\n\n\n\n

    Chemical asphxiants: CO, hydrogen sulfide, HCN<\/p>\n\n\n\n

    3. Dust (P.M)<\/p>\n\n\n\n

    4. Biological agents and disease <\/p>\n\n\n\n

    Virus, bactaria, fugi, parasites etc.<\/p>\n\n\n\n

    The chemicals should be properly identified, classified and handled accordingly.<\/p>\n\n\n\n

    For this purpose some major divisions are given below;<\/p>\n\n\n\n

    Corrosive chemicals: bromine, caustic soda,flourine, sulfuric acid, sulfur chloride, hydrazine, phenol etc.<\/p>\n\n\n\n

    Oxidizing agent: aluminum nitrate, ammonium nitrate, perchlorate, zinc chlorate, zinc peroxide etc.<\/p>\n\n\n\n

    Carcinogens: asbestos, aniline, benzene, chloroform, carbon tetrachloride, styrene, phenol etc.<\/p>\n\n\n\n

    Poisonous chemicals: bromide, chloride, arsenic acid, cyclohexane, phenol, nickel cyanide, phosgene, DDT etc.<\/p>\n\n\n\n

    Pesticides- Insecticides: aldrine, acephate, BHC, cupric sulfate etc.<\/p>\n\n\n\n

    Explosive chemicals: carbon dust, aluminum dust, wood saw dust, potassium nitrate etc.<\/p>\n\n\n\n

    Solvents: methanol, ethanol, benzene, toluene etc.<\/p>\n\n\n\n

    Other flammable chemicals: LPG, ethylene, ethylene oxide, phosphorous, vinyl chloride etc.<\/p>\n\n\n\n

    Reactive chemicals: acetic acid, acetone, sodium, potassium, magnesium aluminium powder etc.<\/p>\n\n\n\n

    Alcohols: methyl, ethyl, amyl etc.<\/p>\n\n\n\n

    Refrigerant gases: ammonia, freon, carbon dioxide etc.<\/p>\n\n\n\n

    Esters: borate, benzoate, cynate<\/p>\n\n\n\n

    Ethers: thio ethers, vinyl ethers etc.<\/p>\n\n\n\n

    Enzymes: catalase, deaminase, lactose etc.<\/p>\n\n\n\n

    Resins: allyl, aminoplastic etc.<\/p>\n\n\n\n

    Acids:<\/p>\n\n\n\n

    In organic: hydorchloric, hydrobromic, hydrofloric etc.<\/p>\n\n\n\n

    Organic: acetic, acrylic, adipic, benzoic etc.<\/p>\n\n\n\n

    Compatible<\/strong>: means which can be stored or handled with that chemical to which it is compatible<\/p>\n\n\n\n

    Incompatible<\/strong>: means which should not be stored or handled with that chemicals to which it is incompatible.<\/p>\n\n\n\n

    Chemicals<\/td>Incompatible chemicals<\/td><\/tr>
    Ammonia<\/td>Mercury, chlorine, calcium hypochlorite, iodine, bromine and hydrogen floride<\/td><\/tr>
    Chlorine<\/td>Ammonia, acetylene, hydrogen, benzene<\/td><\/tr>
