FIRE FIGHTING
FIRE Combustible.
NO open flames.
Water spray, powder, AFFF, foam, carbon dioxide.
EXPLOSION Finely dispersed particles form explosive mixtures in air.
Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding).

EXPOSURE
PREVENT DISPERSION OF DUST!

  • INHALATION
    		• Cough. Nausea. Vomiting.
    		Avoid inhalation of fine dust and mist. Local exhaust or breathing protection.
    		Fresh air, rest. Refer for medical attention.
  • SKIN

    		• Protective gloves.
    		Remove contaminated clothes. Rinse and then wash skin with water and soap.
  • EYES
    		• Redness. Pain.
    		Safety goggles, or eye protection in combination with breathing protection if powder.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
    		• (further see Inhalation).
    		Do not eat, drink, or smoke during work. Wash hands before eating.
    		Rinse mouth. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place (extra personal protection: A/P2 filter respirator for organic vapour and harmful dust).
    		Separated from food and feedstuffs and oxidants.
    		Do not transport with food and feedstuffs.

    PHYSICAL STATE; APPEARANCE:
     WHITE CRYSTALS OR FLAKES , WITH CHARACTERISTIC ODOUR.

    PHYSICAL DANGERS:
     Dust explosion possible if in powder or granular form, mixed with air.

    CHEMICAL DANGERS:
     Reacts with oxidants.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: 0.2 ppm; 1.3 mg/m3 (ACGIH 1993-1994).
    OSHA PEL: TWA 1 mg/m3 (0.2 ppm)
    NIOSH REL: TWA 1 mg/m3 (0.2 ppm)
    NIOSH IDLH: 100 mg/m3


    		ROUTES OF EXPOSURE:
     The substance can be absorbed into the body by inhalation and by ingestion.

    INHALATION RISK:
     A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C.

    EFFECTS OF SHORT-TERM EXPOSURE:
     The substance irritates the eyes and the respiratory tract.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     The substance may have effects on the liver and nervous system , resulting in impaired functions.

    ENVIRONMENTAL
    DATA
         		This substance may be hazardous to the environment; special attention should be given to water. In the food chain important to humans, bioaccumulation takes place, specifically in plants. It is strongly advised not to let the chemical enter into the environment because it persists in the environment.
    N O T E S
    Do NOT take working clothes home. Dowtherm A is a trade name.
