Ingredient	CAS No	Percent	Hazardous
———————	————	————	———
Silica Gel	7631-86-9	99 – 100%	Yes

4. First Aid Measures
Inhalation:
Remove to fresh air. Get medical attention for any breathing difficulty.
Ingestion:
Give several glasses of water to drink to dilute. If large amounts were swallowed, get medical
advice.
Skin Contact:
Immediately flush skin with plenty of soap and water for at least 15 minutes. Remove contaminated
clothing and shoes. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical
attention if irritation develops.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes, lifting upper and lower
eyelids occasionally. Get medical attention if irritation persists.
5. Fire Fighting Measures
Fire:
Not considered to be a fire hazard.
Explosion:
Not considered to be an explosion hazard.
Fire Extinguishing Media:
Use any means suitable for extinguishing surrounding fire.
Special Information:
Use protective clothing and breathing equipment appropriate for the surrounding fire.
6. Accidental Release Measures
Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified
in Section 8. Spills: Sweep up and containerize for reclamation or disposal. Vacuuming or wet

7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against
physical damage. When pouring into a container of flammable liquid, ground both containers
electrically to prevent a static electric spark. Containers of this material may be hazardous
when empty since they retain product residues (dust, solids); observe all warnings and precautions
listed for the product.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
Silica (synthetic, amorphous):
– OSHA Permissible Exposure Limit (PEL) –
80/(%SiO2) mg/m3 (TWA) for amorphous silica, including natural diatomaceous earth.
– ACGIH Threshold Limit Value (TLV) –
10 mg/m3 (TWA) for amorphous precipitated silica and amorphous silica gel.

Ventilation System:
A system of local and/or general exhaust is recommended to keep employee exposures below the
Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it can control
the emissions of the contaminant at its source, preventing dispersion of it into the general
work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended
Practices, most recent edition, for details.

Personal Respirators (NIOSH Approved):
If the exposure limit is exceeded and engineering controls are not feasible, a half facepiece
particulate respirator (NIOSH type N95 or better filters) may be worn for up to ten times the
exposure limit or the maximum use concentration specified by the appropriate regulatory agency
or respirator supplier, whichever is lowest.. A full-face piece particulate respirator (NIOSH
type N100 filters) may be worn up to 50 times the exposure limit, or the maximum use concentration
specified by the appropriate regulatory agency, or respirator supplier, whichever is lowest.
If oil particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present, use a NIOSH
type R or P filter. For emergencies or instances where the exposure levels are not known, use
a full-facepiece positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators
do not protect workers in oxygen-deficient atmospheres.

Skin Protection:
Wear protective gloves and clean body-covering clothing.
Eye Protection:
Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in work area.
