SECTION V
HEALTH HAZARD DATA
Nuisance dust can be released during dry sanding of this product. Eye, skin, nose, throat, and upper respiratory
irritation can occur with prolonged dust exposure.
EFFECTS OF OVEREXPOSURE:
ACUTE:
EYES: Direct contact can cause mechanical irritation of eyes. If burning, redness, itching, pain or other symptoms
persist or develop, consult physician.
SKIN: Direct, prolonged or repeated contact with the skin may cause irritation. May dry skin. Rubbing of this product
against the skin can result in abrasions. Rinse with water until free of material to avoid abrasions, then wash skin
thoroughly with mild soap and water. If irritation persists, consult physician.
INHALATION: Inhalation of dust from this product may irritate the nose, throat, lungs, and upper respiratory tract.
Persons subjected to large amounts of this dust will be forced to leave area because of nuisance conditions such as
coughing, sneezing and nasal irritation from dust. Labored breathing may occur after excessive inhalation. If
respiratory symptoms persist, consult physician.
INGESTION: No known effects.
CHRONIC:
EYES: None known.
SKIN: None known.
INHALATION: This product may contain small amounts of vinyl acetate monomer, vapors of which have been shown to
cause tumors in the respiratory tract of laboratory animals. Chronic overexposure to vinyl acetate is not expected to
occur during normal handling and use of this product. Vinyl acetate has been shown to cause irritation and cancer in
inhalation studies with laboratory animals. Test levels of 600ppm over a lifetime cause an increase in tumors in the
respiratory tract of the test animals. 200ppm caused irritation. No tumors were observed in the animals exposed at
50ppm or lower. There is no evidence of adverse effects to humans exposed to levels at or below the TLV.
Chronic overexposure to respirable crystalline silica may result in lung disease (i.e., silicosis) and/or lung cancer.
INGESTION: No Known effects.
EMERGENCY AND FIRST AID PROCEDURES:
EYES: Flush thoroughly with plenty of water for 15 minutes to remove particles. If irritation persists, consult physician.
SKIN: Rinse with water, then wash with mild soap and water. A commercially available hand lotion may be used to
treat dry skin areas. If skin has become cracked, take appropriate action to prevent infection and promote healing. If
irritation persists, consult physician.
INHALATION: Remove to fresh air. Leave the area of dust exposure and remain away until coughing and other
symptoms subside. Other measures are usually not necessary, however, if conditions warrant, contact physician.

INGESTION: No harmful effects expected. No specific recommendation. If gastric disturbance occurs, call physician.
TARGET ORGANS: Eyes, skin, and respiratory system.
MEDICAL CONDITIONS WHICH MAY BE AGGRAVATED: Pre-existing upper respiratory and lung diseases such as,
but not limited to, bronchitis, emphysema and asthma.
PRIMARY ROUTES OF ENTRY: Inhalation; Eye and/or Skin contact.
CARCINOGENICITY OF INGREDIENTS:
MATERIAL IARC NTP
Respirable Crystalline Silica Group 1 Known
Acetaldehyde 2B Anticipated
Vinyl Acetate Monomer 2B Not Listed
Vinyl acetate monomer and acetaldehyde, if present, are trace components of the vinyl acetate polymer. Quantities of
monomer have not been measured, but would be expected to be less than 0.1 Wt. %.
USG has measured exposure levels of respirable crystalline silica at jobsites during ready-mixed joint compound
applications and sanding for this product. Results of this industrial hygiene testing for USG joint compounds showed no
detection of respirable crystalline silica following NIOSH Method 7500. Industrial hygiene testing on this product for
formaldehyde exposure during mixing and application of ready-mixed joint compound showed no detection of
formaldehyde.
In June, 1997, the International Agency for Research on Cancer (IARC) classified crystalline silica (quartz and
cristobalite) as a human carcinogen. In making the overall evaluation, the IARC Working Group noted that
carcinogenicity in humans was not detected in all industrial circumstances studies. Carcinogenicity may be dependent
on inherent characteristics of the crystalline silica or on external factors affecting its biological activity or distribution of
its polymorphs.
IARC states that crystalline silica inhaled in the form of quartz or cristobalite from occupational sources in carcinogenic
to humans (Group 1).
SECTION VI
REACTIVITY DATA
Stable.
STABILITY:
None known.
INCOMPATIBILITY:
Will not occur.
HAZARDOUS POLYMERIZATION:
CO2 would be produced at high temperatures with the decomposition of
HAZARDOUS DECOMPOSITION:
limestone (~800潞C). Stable under normal temperature and pressure. Product
contains low level of organic volatiles which may be emitted or released in
application processes involving the use of heat. Vent all ovens and process
vessels to the outside atmosphere. Thermal decomposition will produce H2O,
CO2, CO, and acetic acid. Could produce vinyl acetate monomers when
temperature is above 175潞C.
SECTION VII
SPILL OR LEAK PROCEDURES
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED:
Use normal clean up procedure. Spilled material can produce slippery conditions, be cautious to avoid falling. Wear
appropriate protective equipment. Shovel material from spillage into a waste container for disposal.

WASTE DISPOSAL METHOD:
Dispose of material in accordance with federal, state, and local regulations.
SECTION VIII
SPECIAL PROTECTION INFORMATION
No TLV assigned to this mixture; see Ingredients Section. Minimize dust exposures in accordance with good hygiene
practice.
RESPIRATORY PROTECTION:
Not typically necessary under normal conditions of use. Provide general ventilation and local exhaust ventilation to
meet TLV requirements of individual ingredients and to control dusting conditions. Wear a NIOSH/MSHA-approved
respirator when dusty conditions exist, in poorly ventilated areas, and if TLV is exceeded.
VENTILATION:
Ventilate to keep exposures below TLV. General ventilation is expected to be satisfactory. Use local exhaust
ventilation if necessary to control dust.
PERSONAL PROTECTIVE EQUIPMENT:
Wear eye protection (safety glasses or goggles) to avoid particulate irritation of the eye. Gloves or protective clothing
are usually not necessary, but may be desirable in specific work situations. Wear adequate clothing to minimize
chafing or drying of skin.
SECTION IX
SPECIAL PRECAUTIONS
PRECAUTIONS TO BE TAKEN IN HANDLING AND STORAGE:
Normal precautions should be followed in handling, storage, and use. During handling and use wear the appropriate
respiratory, eye and skin protection of warranted per environmental conditions.
Use wet sanding technique to reduce dust exposure when finishing joints. See 鈥淔inishing and Decorating Gypsum
Panels 鈥? Wet Sanding, J-610/12-87鈥?.
Recommended Storage Methods: Store at room temperature in a dry location. Protect from freezing, extreme heat,
and exposure to direct sunlight. Keep tightly sealed.
鈭哤ARNING!
Dust generated from sanding product may cause eye, skin, nose, throat or respiratory irritation. Use wet-sanding to
avoid creating dust. Avoid inhalation of dust and eye contact. If dusty, wear a NIOSH/MSHA-approved respirator.
Provide good general ventilation and local exhaust ventilation to avoid excessive amounts of dust. Wear eye
protection. If eye contact occurs, flush thoroughly with water for 15 minutes. If irritation persists, call physician. Do not
ingest. If ingested, call physician. Do not use if material has spoiled, i.e., there is a moldy appearance or an
unpleasant odor. Close container and discard properly. Product safety information: (800) 507-8899.
KEEP OUT OF REACH OF CHILDREN.
