POTENTIAL HEALTH EFFECTS
ACUTE:
Eyes: Airborne dust during sanding or 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.
Inhalation: Inhalation of dust during sanding can irritate the nose, throat, and the 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. Labored breathing may occur after excessive inhalation. If respiratory symptoms persist,
consult physician.
Ingestion: If ingested may cause temporary irritation to the gastrointestinal tract, especially the stomach. No known
effects.
CHRONIC:
Eyes: None known.
Skin: None known.
Ingestion: No known effects.
Inhalation: Industrial hygiene atmospheric respirable crystalline silica testing during the use and application of USG joint
compounds did not detect any concentration of respirable crystalline silica exposure. Exposures to respirable crystalline
silica are not expected during the normal use of this product; however, actual levels must be determined by workplace
hygiene testing.
Prolonged and repeated exposure to airborne free respirable crystalline silica can result in lung disease (i.e., silicosis)
and/or lung cancer. The development of silicosis may increase the risks of additional health effects. The risk of
developing silicosis is dependent upon the exposure intensity and duration.
TARGET ORGANS: Eyes, skin and respiratory system.
PRIMARY ROUTES OF ENTRY: Inhalation, eyes and skin contact.
SECTION 4
FIRST AID MEASURES
FIRST AID PROCEDURES
Eyes: In case of contact, do not rub or scratch your eyes. Flush thoroughly with water for 15 minutes to remove
particles. If irritation persists, consult physician.
Skin: 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: This product is not intended to be ingested or eaten. No harmful effects expected. No specific
recommendations. If gastric disturbance occurs, call physician.
MEDICAL CONDITIONS WHICH MAY BE AGGRAVATED: Pre-existing upper respiratory and lung diseases such as,
but not limited to, bronchitis, emphysema and asthma. Pre-existing skin diseases such as, but not limited to, rashes and
dermatitis.

CLEAN-UP:
Use normal clean up procedures. Wear appropriate protective equipment. Ventilate area. Floor may be slippery; use
care to avoid falling. Shovel or scoop up material from spillage into a waste container for disposal.
DISPOSAL:
Follow all local, state, provincial and federal regulations. Never discharge large releases directly into sewers or surface
waters. Trace amounts of residue can be flushed to a drain, using plenty of water.
SECTION 7
HANDLING AND STORAGE
HANDLING:
When sanding, minimize dust generation and accumulation. Avoid breathing dust. Wear the appropriate respiratory
protection against dust in poorly ventilated areas and if TLV is exceeded (see Sections 2 and 8). Avoid dust contact with
eyes. Wear the appropriate eye protection against dust (See Section 8).
Use good safety and industrial hygiene practices.
STORAGE:
Store at room temperature in a dry location.
Protect from freezing, extreme heat, and exposure to direct sunlight.
Do not use if material has spoiled, i.e., there is a moldy appearance or an unpleasant odor. Close container and discard
properly.
Keep tightly sealed following use.

SECTION 8
EXPOSURE CONTROLS / PERSONAL PROTECTION
ENGINEERING CONTROLS:
Provide ventilation sufficient to control airborne dust levels especially respirable crystalline silica.
If user operations generate airborne dust, use ventilation to keep dust concentrations below permissible exposure limits
(See Section 2).
Where general ventilation is inadequate, use process enclosures, local exhaust ventilation, or other engineering controls
to control dust levels below permissible exposure limits (see Section 2). If engineering controls are not possible, wear a
properly fitted NIOSH/MSHA-approved particulate respirator.
RESPIRATORY PROTECTION:
Wear a NIOSH/MSHA-approved respirator equipped with particulate cartridges when dusty in poorly ventilated areas,
and if TLV is exceeded. A respiratory program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements
must be followed whenever workplace conditions warrant a respirator's use.
OTHER PERSONAL PROTECTIVE EQUIPMENT:
Eye/Face: Wear eye protection (safety glasses or goggles) to avoid particulate irritation of the eye.
Skin: Gloves or protective clothing are usually not necessary but may be desirable in specific work situations. For brief
contact, no precautions other than clean body-covering clothing should be needed. Wear gloves and protective clothing
to prevent repeated or prolonged skin contact. Barrier creams or skin lotion may be applied to face, neck, wrist and
hands when skin is exposed to help prevent drying of skin.
General: Selection of Personal Protective Equipment will depend on environmental working conditions and operations.

TOXICOLOGICAL INFORMATION
ACUTE EFFECTS:
Direct contact may cause eye, skin and/or respiratory irritation.
LD50: Not Available for product.
LC50: Not Available for product.
CHRONIC EFFECTS / CARCINOGENICITY:
Crystalline silica: Industrial hygiene atmospheric respirable crystalline silica testing during the use and application of
USG joint compounds did not detect any concentration of respirable crystalline silica exposure. Exposures to respirable
crystalline silica are not expected during the normal use of this product; however, actual levels must be determined by
workplace hygiene testing.
Prolonged and repeated exposure to airborne free respirable crystalline silica can result in lung disease (i.e., silicosis)
and/or lung cancer. The development of silicosis may increase the risks of additional health effects. The risk of
developing silicosis is dependent upon the exposure intensity and duration.
In June, 1997, 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 studied. 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 is carcinogenic to
humans (Group 1).
Vinyl acetate/acetaldehyde/formaldehyde: A component of this product is a common emulsion polymer most familiar
as the component of ordinary white glue which exhibits the 鈥渟ticky鈥? characteristic. The emulsion polymer is not classified
as a carcinogen by IARC, NTP or ACGIH. However, trace amounts of residual vinyl acetate monomers, acetaldehyde
and formaldehyde may be associated with the production of the emulsion polymer.
Any exposure to vinyl acetate monomer, acetaldehyde, or formaldehyde is expected to remain well below OSHA
regulatory and ACGIH recommended limits during normal handling and use of this product.
Industrial hygiene atmospheric formaldehyde testing during the use and application of USG joint compounds did not
detect any concentration of formaldehyde exposure.

ECOLOGICAL INFORMATION
ENVIRONMENTAL TOXICITY: This product has no known adverse effect on the ecology. A large discharge directly
into waterways would not be expected to kill aquatic life.
Ecotoxicity value: Not determined.
SECTION 13
DISPOSAL CONSIDERATIONS
WASTE DISPOSAL METHOD:
Dispose of material in accordance with Federal, State, Provincial, and Local regulations. Consult with environmental
regulatory agencies for guidance on acceptable disposal practices. Never discharge directly into sewers or surface
waters.
