Specification

Ingestion: Expected to be practically non-toxic. Ingestion of large amounts may cause gastrointestinal irritation
and blockage.
Inhalation: Dusts may irritate the nose, throat, and respiratory tract by mechanical abrasion. Coughing,
sneezing, and shortness of breath may occur following exposures in excess of appropriate exposure limits. Use
of natural sand and gravel for construction purposes is not believed to cause additional acute toxic effects.
However, repeated overexposure to very high levels of respirable crystalline silica (quartz, cristobalite, tridymite)
for periods as short as six months have caused acute silicosis. Acute silicosis is a rapidly progressive, incurable
lung disease that is typically fatal. Symptoms include (but are not limited to); shortness of breath, cough, fever,
weight loss, and chest pain.
FIRST AID:
Eyes: Immediately flush eye(s) with plenty of clean water for at least 15 minutes, while holding the eyelid(s)
open. Occasionally lift the eyelid(s) to ensure thorough rinsing. Beyond flushing, do no attempt to remove
material from the eye(s). Contact a physician if irritation persists or later develops.
Skin: Wash with soap and water. Contact a physician if irritation persists or later develops.
Ingestion: If person is conscious, give large quantity of water and induce vomiting; however, never attempt to
make an unconscious person drink or vomit. Get immediate medical attention.
Inhalation: Remove to fresh air. Dust in throat and nasal passages should clear spontaneously. Contact a
physician if irritation persists or later develops.

SECTION VII - PERSONAL PROTECTION AND CONTROL MEASURES
RESPIRATORY PROTECTION: To minimize exposure to dust and/or crystalline silica, NIOSH/MSHA approved
respirators must be worn in accordance with a respiratory protection program which meets OSHA requirements
as set forth at 29 CFR 1910.134 and ANSI Z88.2-1080 “Practices for Respiratory Protection.”
SKIN PROTECTION: Use gloves and/or protective clothing if abrasion or allergic reactions are experienced.
EYE PROTECTION: Use safety glasses with side shields. Dust goggles should be worn when excessively
