EXPOSURE
PREVENT DISPERSION OF DUST!

  • INHALATION

    		• Local exhaust or breathing protection.
    		Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
  • SKIN

    		• Protective gloves. Protective clothing.
    		Remove contaminated clothes. Rinse and then wash skin with water and soap.
  • EYES

    		• Safety goggles.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION



    • SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place (extra personal protection: P2 filter respirator for harmful particles).
    		Store in covered containers.

    PHYSICAL STATE; APPEARANCE:
     PALE YELLOW TO AMBER, FRAGMENTS OR POWDER.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     On combustion, forms irritating and toxic gases including formaldehyde.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: (Core solder thermal decomposition products as resin acids): Sensitizer; reduce exposure as low as possible ppm; mg/m3 (ACGIH 1993-1994).
    PDK not established.
    MAK not established.


    		ROUTES OF EXPOSURE:
     The substance can be absorbed into the body by inhalation of fumes.

    INHALATION RISK:

    EFFECTS OF SHORT-TERM EXPOSURE:
     Inhalation of dusts or fumes may cause asthmatic reactions (see Notes). Inhalation of fumes may cause eyes and respiratory tract irritation.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation exposure may cause asthma.
    PHYSICAL
    PROPERTIES
    Melting point: 100-150░C
    Relative density (water = 1): 1.1
    		 Solubility in water: none
    Relative vapour density (air = 1): 1.07-1.09
    ENVIRONMENTAL
    DATA
    N O T E S
    Rosin is obtained from pine trees. Rosin is available as wood rosin, gum rosin or tall oil rosin. Anyone who has shown symptoms of asthma due to this substance should avoid all further contact with this substance. Workers who are exposed to rosin fumes should wear protective clothing.
