CARCINOGENICITY
*: The composition of SiO 2 may be up to 100% crystalline silica. (R): Respirable (T): Total §: Crystalline silica is
normally measured as respirable dust. The OSHA standard also presents a formula for calculation of the PEL
based on total dust: 30 mg/m 3 / (% SiO 2 + 2). #: Particulate matter containing no asbestos and <1% crystalline
silica.

SECTION 4: FIRST AID MEASURES
Respiratory, hand and eye protection may be needed to prevent excess exposure to airborne particulates if dust is produced by
cutting or if dust is produced by any other operations, including removal.
EYES: Do not rub eyes in order to avoid possible cornea damage as a result of mechanical stress. Check for and remove any
contact lenses. Rinse out with water with eyelid held wide open. Do not attempt to remove any material from the eye. Get
medical attention if irritation persists.
SKIN: Wash off immediately with soap and plenty of water. Remove contaminated clothing and was work clothes after each use.
Get medical attention if irritation persists.
INGESTION: Rinse out mouth and make victim drink plenty of water. Never give anything by mouth to an unconscious
person. Do NOT induce vomiting unless directed to do so by medical personnel; call for medical help.
INHALATION: Remove from exposure. Keep warm and at rest and provide fresh air. Dust in throuat and nasal passages
should clear spontaneously. Get medical attention if irritation persists.
