Not dangerous for supply.
8. ACUTE HEALTH HAZARDS & ADVICE:
Dantex Jointseal N1® presents no acute health hazard at ambient temperature. However, as these materials are normally handled at elevated temperatures when their physical state changes to a liquid, the bitumens present in these products give of fumes which are undesirable to inhale as very small quantities of HYDROGEN SULPHIDE may be present in the bitumen.
RECOMMENDED PROTECTIVE CLOTHING
Overalls, Goggles / Visor and Closed Safety Boots when handling hot product.
Inhalation of the vapours should be avoided.
INHALATION FIRST AID
Remove the affected person to fresh air. If breathing has stopped administer artificial respiration. Give cardiac massage if necessary. If the person is breathing but unconscious place in the recovery position. Obtain medical assistance immediately.
SKIN CONTACT FIRST AID
Bituminous products present no acute health hazards to the skin other than burning when handling at elevated temperatures.
Flush the contaminated skin with cold water. DO NOT ATTEMPT TO REMOVE THE BITUMEN. Cover the burn with a sterile dressing. Do not apply any medication to the affected part. Obtain medical attention immediately.
Contact with fumes may cause irritation and redness.
Irrigate with copious amounts of water for 10 / 20 minutes and seek medical advice immediately.
Avoid contact with the skin by use of suitable protective clothing.
Not classified as dangerous for transportation
