    ECHEMI Editorial Reference
    Naphthalene is a crystalline, white, flammable, polycyclic aromatic hydrocarbon consisting of two fused benzene rings. It has a pungent odor and sublimes readily above its melting point; it has been traditionally used in moth balls and is responsible for the moth balls characteristic odor. Naphthalene is a natural component of fossil fuels and is the single most abundant component of coal tar, accounting for approximately 11% of dry coal tar. Naphthalene is a colorless to brown crystalline soli

    Handling and Storage

    Precautions for safe handling

    NO open flames. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.

    Conditions for safe storage, including any incompatibilities

    Separated from strong oxidants and food and feedstuffs. Store in an area without drain or sewer access. Provision to contain effluent from fire extinguishing.Without inert-gas blanketing and at the temperature normally used for the storage of molten naphthalene, i.e., 90 deg C, the vapors above the liquid are within the flammability limits. Thus, storage tanks containing molten naphthalene have a combustible mixture in the vapor space and care must be taken to eliminate all sources of ignition around such systems. Naphthalene dust can form explosive mixtures with air which necessitates the design and operation of solid handling systems.
