Section III. Hazards Identification
Not an acute hazard. Contains quartz. May cause mechanical eye or skin irritation in high concentrations.
Emergency Overview
As with all mineral spills, minimize dusting during clean-up. Do not breathe dust. Prolonged inhalation may
cause lung injury. Product can become slippery when wet.
Pulmonary System (chronic risk).
Target Organs
Section IV. First Aid Measures
Flush with plenty of flowing water. Get medical attention if irritation persists.
Eye Contact
Wash off with water.
Skin Contact
Allow the victim to rest in a well ventilated area if high concentration is inhaled and mechanical irritation or
Inhalation
discomfort occurs. Seek medical attention if irritation persists.
Unlikely to be toxic by ingestion.

Hazards
Section VI. Accidental Release Measures
Put spilled solid in a waste disposal container. Finish cleaning by spreading water on the contaminated
Small Spill
surface and dispose of according to local and state regulations.
Use a shovel to put the material into a proper waste disposal container. Finish cleaning by spreading water
Large Spill
on the contaminated surface and dispose of according to local and state regulations. Be careful that the
product is not present at a concentration level above TLV. Check Section XIII for disposal information.
Section VII. Handling and Storage
No special storage considerations. Handle in ways which minimize dust generation.
Handling and Storage
Procedures
Section VIII. Exposure Controls, Personal Protection
Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below
Engineering Controls
recommended exposure limits. If user operations generate dust, use ventilation to keep exposure to airborne
contaminants below the exposure limit.
If local exhaust ventilation is used, a capture velocity of 150-200 fpm is recommended.
Safety glasses. Any NIOSH approved filter dust respirator. No special skin protection is required. Wash skin

PYROPHYLLITE: In the absence of crystalline silica, pyrophyllite can cause a low category pneumoconiosis
Remarks
(with little respiratory disability) in prolonged, high dust concentrations.
KAOLIN: Published literature suggests that extremely high exposures to kaolin dust over a prolonged period
of time can lead to a low category pneumoconiosis (with little respiratory disability) in a small number of
workers.
CRYSTALLINE SILICA: Overexposure to respirable crystalline silica dust can cause silicosis, a form of
progressive pulmonary fibrosis. "Inhalable" crystalline silica (quartz) is listed by IARC as a Group I
carcinogen (lung) based on "sufficient evidence" in occupationally exposed humans and sufficient evidence in
animals. Crystalline silica is also listed by the NTP as a known human carcinogen. Some studies have not
demonstrated a cancer association and considerable controversy exists concerning the IARC and NTP
classification.
Excessive exposure to any dust may aggravate pre-existing respiratory conditions. Repeated or prolonged
exposure can produce damage to the lungs.
