    See Chlorine-releasing compounds and Antiseptics and disinfectants, Part two.

    Precautions

    • Prepare solutions with cold water, in non metallic containers.
    • NaDCC can corrode metal. The risk is limited for good quality stainless steel instruments if concentration, contact time (20 minutes maximum) and thorough rinsing recommendations are respected.
    • For disinfection of linen: use only for white cotton or linen (risk of discolouration).
    • Do not expose the product to flames. Do not incinerate.
    • DO NOT SWALLOW. Do not store NaDCC tablets near oral tablets.
    • Avoid inhaling vapours and dust when opening or handling the containers.
    • Do not mix with acid solutions such as urine, etc. (release of toxic chlorine gas) and detergents.

    Remarks

    • NaDCC may be used for wound antisepsis but only if the formulation is intended for this purpose: 0.1% active chlorine solution (1000 ppm): 1 tablet of 1 g active chlorine per litre. For prolonged use, protect the healthy skin around the wound with vaseline.

    Caution: some formulations used for disinfecting floors contain additives (detergents, colouring, etc.) and cannot be used on wounds. Check label or leaflet.

    • Some formulations can be used for the disinfection of drinking water (Aquatabs®, etc.). Follow manufacturer's instructions.
    • NaDCC is also called sodium troclosene, sodium dichloro-s-triazinetrione.
