Potential Health Effects
----------------------------------
Inhalation: May cause irritation to the respiratory tract. Symptoms may include coughing and shortness of
breath. Inhalation can cause a flu-like illness (metal fume fever). This 24- to 48-hour illness is characterized by
chills, fever, aching muscles, dryness in the mouth and throat and headache.
REAGENTS, INC.--MSDS鈥擹INC OXIDE PAGE 2 OF 5
Ingestion: Large oral doses may cause irritation to the gastrointestinal tract.
Skin Contact: Not expected to be a health hazard from skin exposure.
Eye Contact: Not expected to be a health hazard.
Chronic Exposure: No information found.
Aggravation of Pre-existing Conditions: Persons with a pre-existing heart condition or impaired respiratory
function may be more susceptible to the effects of this substance.
4. First Aid Measures
Inhalation: Remove to fresh air. Get medical attention for any breathing difficulty.
Ingestion: Not expected to require first aid measures. If large amounts were swallowed, give water to drink and
get medical advice.
Skin Contact: Not expected to require first aid measures. Wash exposed area with soap and water. Get medical
advice if irritation develops.
Eye Contact: Not expected to require first aid measures. Wash thoroughly with running water. Get medical
advice if irritation develops.
5. Fire Fighting Measures
Fire: Not considered to be a fire hazard.
Explosion: Finely divided powder presents an explosion hazard.
Fire Extinguishing Media: Use any means suitable for extinguishing surrounding fire.
Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained
breathing apparatus with full-facepiece operated in the pressure demand or other positive pressure mode. Zinc
oxide fume may be released when heated.
6. Accidental Release Measures
Clean-up personnel require protective clothing and respiratory protection from dust. 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 sweeping may be used to avoid dust dispersal.
7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage.
Isolate from incompatible substances. 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: Zinc oxide:
-OSHA Permissible Exposure Limit (PEL): fume: 5 mg/m3 (TWA) respirable fraction: 5 mg/m3 (TWA) total
dusts: 15 mg/m3 (TWA)
-ACGIH Threshold Limit Value (TLV):2 mg/m3 (TWA), 10 mg/m3 (STEL), respirable fraction
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
REAGENTS, INC.--MSDS鈥擹INC OXIDE PAGE 3 OF 5
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, a half-face dust/mist respirator
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-facepiece dust/mist respirator
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. 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.
9. Physical and Chemical Properties
Appearance: White to yellowish-white amorphous powder.
Odor: Odorless.
Solubility: Insoluble in water, alcohol; soluble in dilute acids.
Specific Gravity: 5.67
pH: No information found.
% Volatiles by volume @ 21C (70F): 0
Boiling Point: Sublimes.
Melting Point: 1975C (3587F)
Vapor Density (Air=1): No information found.
Vapor Pressure (mm Hg): No information found.
Evaporation Rate (BuAc=1): No information found.
10. Stability and Reactivity
Stability: Stable under ordinary conditions of use and storage. Absorbs carbon dioxide from air.
Hazardous Decomposition Products: When heated to very high temperatures, zinc oxide sublimes to produce
toxic fumes.
Hazardous Polymerization: Will not occur.
Incompatibilities: Has exploded when mixed with chlorinated rubber. Reacts violently with magnesium, linseed
oil. Zinc oxide and magnesium can react explosively when heated.
Conditions to Avoid: Heat, incompatibles.
