TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Not combustible.		In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION

EXPOSURE		PREVENT DISPERSION OF DUST!
Inhalation		Avoid inhalation of fine dust and mist. Local exhaust or breathing protection.	Fresh air, rest.
Skin		Protective gloves.	Rinse and then wash skin with water and soap.
Eyes		Safety spectacles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Sweep spilled substance into covered containers; if appropriate, moisten first to prevent dusting. Personal protection: P1 filter respirator for inert particles.

EMERGENCY RESPONSE	SAFE STORAGE

IMPORTANT DATA

Physical State; Appearance
WHITE POWDER.

Occupational exposure limits
TLV: (Respirable fraction) 2 mg/m³ as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004).

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol.

Inhalation risk
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.

Effects of long-term or repeated exposure
Lungs may be affected by repeated or prolonged exposure to dust particles. The substance may have effects on the lungs, resulting in fibrosis (kaolinosis) and impaired functions.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Relative density (water = 1): 2.6 Solubility in water: none

NOTES

This card applies to kaolin containing <1% crystalline silica. If kaolin contains more than 1% crystalline silica,
fusion temperature 1785°C.
Depending on the degree of exposure, periodic medical examination is suggested.
Fitrol, Glomax, Kaophills-2 are trade names.

Card has been partly updated in April 2005. See section Occupational Exposure Limits.
