HAZARD IDENTIFICATION
Material Safety Data Sheet MSDS No. 114
HASA DIATOMACEOUS EARTH (D.E.)
Summary: This product contains Crystalline Silica (CS), which is considered a hazard by inhalation. IARC
has classified inhalation of CS as carcinogenic for humans (group 1). CS is listed by NTP as known human
carcinogen. Inhalation of CS is also a known cause of silicosis, a noncancerous lung disease.
Medical conditions which Pre-existing upper respiratory and lung disease such as but not limited to
may be aggravated: bronchitis, emphysema and asthma.
Target Organ(s): Lungs, Eyes
Acute Health Effects: Transitory upper respiratory or eye irritation.
Chronic Health Effects: Inhalation of Crystalline Silica has been classified by IARC as carcinogenic
for humans (group 1). Inhalation of Crystalline Silica is also a known cause of
silicosis, a noncancerous lung disease caused by excessive exposure to
Crystalline Silica.
Primary Entry Route(s): Inhalation. Dust contact with eyes.
FIRST AID MEASURES
Inhalation: Remove to fresh air. Drink water to clear throat and blow nose to evacuate dust.
Eyes: Flush eyes with large quantities of water. If irritation persists consult a physician.
Skin Contact: NA
Skin Absorption: NA
Ingestion: Not hazardous when ingested.
FIRE FIGHTING MEASURES
Flash Point (Method): Nonflammable
NFPA Flammable/Combustible Liquid Classification: NA
Flammable Limits: LEL: NA UEL: NA
Auto-ignition Temperature: NA
Extinguishing Media: NA
Unusual Fire or Explosion Hazards: None
Special Fire-Fighting Procedures: None
ACCIDENTAL RELEASE MEASURES
Procedure for Spill/Leak: Vacuum clean dust with equipment fitted with HEPA filter. Use a Dust
Suppressant such as water if sweeping is necessary.
HANDLING AND STORAGE
Minimize dust generation and accumulation. Avoid breathing dust. Avoid contact with eyes. Seal broken
bags immediately. Continue to follow all MSDS/LABEL warnings when handling empty containers.
EXPOSURE CONTROLS/PERSONAL PROTECTION
Goggles: Goggles or Safety Glasses with Sideshields are recommended.
Gloves: Not normally required.
Respirator: < 10X PEL, Use an N95 Quarter or Half Mask Respirator;
< 50X PEL, Use a full face Respirator equipped with N95 Filters;
< 200X PEL, Use a powered air purifying Respirator (positive pressure) with N95 Filters;
< 200X PEL, Use a full face, Type C supplied air Respirator (continuous flow mode).
Ventilation: Use sufficient natural or mechanical ventilation to keep dust level below PEL.
Other: Special Considerations for repair/maintenance of contaminated equipment:
Insure proper respiratory protection.
