SYMPTOMS 		PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Combustible.
NO open flames.
Powder, carbon dioxide.
EXPLOSION Finely dispersed particles form explosive mixtures in air. Risk of fire and explosion as a result of polymerization reactions.
Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.
In case of fire: cool drums, etc., by spraying with water but avoid contact of the substance with water.
EXPOSURE
STRICT HYGIENE!

  • INHALATION
    		• Burning sensation. Cough. Sore throat.
    		Local exhaust or breathing protection.
    		Fresh air, rest. Refer for medical attention.
  • SKIN
    		• Redness.
    		Protective gloves. Protective clothing.
    		Remove contaminated clothes. Rinse skin with plenty of water or shower.
  • EYES
    		• Redness. Pain.
    		Safety goggles, or eye protection in combination with breathing protection.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
    		• Abdominal pain. Nausea. Sore throat. Vomiting.
    		Do not eat, drink, or smoke during work.
    		Rinse mouth. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Collect leaking and spilled liquid in sealable containers as far as possible. Sweep spilled substance into containers. Do NOT absorb in saw-dust or other combustible absorbents (extra personal protection: A/P2 filter respirator for organic vapour and harmful dust).
    		Separated from strong oxidants, bases. Cool. Dry. Store only if stabilized.
    		Airtight.

    PHYSICAL STATE; APPEARANCE:
     PALE YELLOW LIQUID OR YELLOW CRYSTALS.

    PHYSICAL DANGERS:
     The vapour is heavier than air. Dust explosion possible if in powder or granular form, mixed with air.

    CHEMICAL DANGERS:
     The substance may polymerize quickly on standing or under the influence of water, base(s) and temperatures above 50░C with fire or explosion hazard. The substance is a strong reducing agent and reacts violently with oxidants. The solution in water is a weak acid.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV not established.
    MAK not established.


    		ROUTES OF EXPOSURE:
     The substance can be absorbed into the body by inhalation of its vapour or its aerosol, and by ingestion.

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

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

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     Repeated or prolonged contact may cause skin sensitization. May cause genetic damage in humans.

    ENVIRONMENTAL
    DATA
    N O T E S
    The substance is commercially available as a crystalline dihydrate (80% glyoxal), or as a 40% aqueous solution which may contain polymerization inhibitors. An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert. Daicel GY 60, Glyfix CS 50, Gohsezal P, Permafresh 114 are trade names.
