SECTION 3 HAZARD IDENTIFICATION (continued)
EMERGENCY OVERVIEW
This product is not expected to produce any unusual hazards during normal use. Exposure to high dust levels may
irritate the skin, eyes, nose, throat, or upper respiratory tract.
ACUTE:
Eyes: Airborne dust or direct contact can cause mechanical irritation of eyes. If burning, redness, itching, pain or other
symptoms persist or develop, consult physician.
Skin: No toxic effects from powdered gypsum are noticed where air contains contaminate to excess. This material
exhibits some affinity for moisture, and frequent exposures may have a drying effect on the skin. Possible itching and
irritation may be experienced. This may lead to dermatitis. No penetration of intact skin.
Inhalation: Inhalation of dust 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: Unlikely to occur, but may cause gastric disturbances if swallowed. Gypsum is non-toxic; however, ingestion
of a sufficient quantity could lead to mechanical obstruction of the gut, especially the pyloric region. See First Aid
Measures - Ingestion (Section 4).
CHRONIC:
Inhalation: The concentration of respirable crystalline silica measured in bulk samples of USG gypsum was less than
0.1 Wt.%. Industrial hygiene testing, following the NIOSH Method 7500, did not detect respirable crystalline silica in dust
created during the cutting of USG gypsum wallboard panels by both the recommended score and snap technique and
with the use of a power saw in a 10ft by 10ft room.
Gypsum wallboard panels do not release respirable dust in their installed state and therefore do not present any known
health hazards when installed and properly maintained.
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. 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.
Eyes: None known.
Skin: Prolonged and repeated exposure may dry skin and possibly lead to dermatitis.
Ingestion: No known effects.
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: 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: No harmful effects expected. No specific recommendations. Calcium sulfate is nontoxic; however, ingestion
of a sufficient quantity could lead to mechanical obstruction of the gut, especially the pyloric region. If gastric disturbance
occurs, call physician. Drinking gelatin solutions or large volumes of water may delay setting.
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.

ACCIDENTAL RELEASE MEASURES
CONTAINMENT:
No special precautions. Wear appropriate personal protection (See Section 8). Collect the material from spillage and if
not damaged or containated by foreign material, gypsum panels may be reclaimed. Contain the spill by keeping it dry
and away from incompatibles (See Section 10).
CLEAN-UP:
Use normal clean up procedures. Wear appropriate protective equipment. If dry, shovel or sweep up material from
spillage and place collected material into a container for recovery or waste disposal. Avoid dust generation. Avoid
inhalation of dust and contact with eyes and skin. Maintain proper ventilation. If vacuum is used to collect dust, use an
industrial vacuum cleaner with a high efficiency air filter. If sweeping is necessary, use dust suppressant. Do not use
compressed air for clean up. These procedures will help minimize potential exposures. If washed down, may plug
drains.
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:
Avoid dust contact with eyes. Wear the appropriate eye protection against dust (See Section 8).
Avoid breathing dust. Wear the appropriate respiratory protection against dust in poorly ventilated areas and if TLV is
exceeded (see Sections 2 and 8).
Minimize dust generation and accumulation. Use good safety and industrial hygiene practices.
When moving board with a forklift or similar equipment, it is essential that the equipment be rated capable of handling
the loads. The forks should always be long enough to extend completely through the width of the load. Fork spacing
between supports should be one half the length of the panels or base being handled so that a maximum of 4鈥? extends
beyond the supports on either end.
Follow traditional building practices; such as management of water away form the interior of the structure to avoid the
growth of mold, mildew and fungus. Remove any building products suspected of being exposed to sustained moisture
and considered conducive to mold growth from the jobsite.
Gypsum panels are very heavy awkward loads posing the risk of severe back injury. Use proper lifting techniques.

SECTION 7 HANDLING AND STORAGE (continued)
STORAGE:
Store in a cool, dry, ventilated area away from sources of heat, moisture and incompatibilities (see Section 10).
Protect product from physical damage.
Protect from weather and prevent exposure to sustained moisture.
Gypsum Association literature recommends storing board flat to avoid damaging edges, warping the board and the
potential safety hazards of the board falling over. However, in other situations, storing the board flat may cause a
tripping hazard or exceed floor limit loads. If stacking board vertically, leave at least 4 inches from the wall to decrease
the risk of falling board and no more than 6 inches to avoid too much lateral weight against the wall.
SECTION 8
EXPOSURE CONTROLS / PERSONAL PROTECTION
ENGINEERING CONTROLS:
Good general ventilation should be sufficient to control airborne dust levels.
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).
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 [chemical gloves are
not necessary, there is no chemical irritation hazard] 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:
Gypsum paste applied experimentally to the eyes of rabbits was not an irritant.
Gypsum dust particulate has shown an irritant action on mucous membranes of the respiratory tract and eyes.
There have been anecdotal reports of conjunctivitis, chronic rhinitis, laryngitis, pharyngitis, impaired sense of smell and
taste, bleeding from the nose, and reactions of tracheal and bronchial membranes in exposed workers.
The sulfate ion has caused gastro-intestinal disturbance in humans following large oral doses.
Limited studies involving the repeated inhalation of an (unspecified) calcium sulfate failed to identify any particular target
organs in monkeys, rats and hamsters.
No evidence of mutagenicity was found in Ames bacterial tests.
LD50: Not Available for product.
LC50: Not Available for product.
CHRONIC EFFECTS / CARCINOGENICITY:
Crystalline silica: The concentration of respirable crystalline silica measured in bulk samples of USG gypsum was less
than 0.1 Wt.%. Industrial hygiene testing, following the NIOSH Method 7500, did not detect respirable crystalline silica in
dust created during the cutting of USG gypsum wallboard panels by both the recommended score and snap technique
and with the use of a power saw in a 10ft by 10ft room.
Gypsum wallboard panels do not release respirable dust in their installed state and therefore do not present any known
health hazards when installed and properly maintained.
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. 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.
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).
