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. When mixed with water, this material hardens and
becomes very hot 鈥? sometimes quickly. DO NOT attempt to make a cost enclosing any part of the body using this
material.

SECTION 3 HAZARD IDENTIFICATION (continued)
POTENTIAL HEALTH EFFECTS
ACUTE:
Eyes: Direct contact can cause mechanical irritation of eyes. If burning, redness, itching, pain or other symptoms
persist or develop, consult physician.
Skin: When mixed with water, this material hardens and becomes very hot 鈥? sometimes quickly. DO NOT attempt to
make a cost enclosing any part of the body using this material. Failure to follow these instructions can cause severe
burns that may require surgical removal of affected tissue or amputation of limb. Direct, prolonged or repeated contact
with the skin may cause irritation. Rinse with water until skin is free of material to avoid irritation, then wash skin
thoroughly with mild soap and water. Repeated exposure may dry skin.
Inhalation: Dust exposures generated during the handling of the product may irritate eyes, skin, nose, throat, 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. Labored breathing may occur after excessive
inhalation. If respiratory symptoms persist, consult physician.
Ingestion: Unlikely to occur, but if ingested may cause gastric disturbances if swallowed. Plaster of paris 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: Testing of dust from USG plaster of paris has not detected respirable crystalline silica. 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. The weight percent of respirable crystalline silica has not been measured in
this product.
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.
Skin: Repeated contact may dry the skin, causing cracking or dermatitis. Sensitive individuals may develop an allergic
dermatitis.
Eyes: No known effects.
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. 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. If gastric disturbance occurs, call physician. This
product contains gypsum plaster. Plaster of paris hardens and, if ingested, may result in obstruction of the gut,
especially the pyloric region. 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.
Notes to Physician: Treatment should be directed at the control of symptoms and the clinical condition.

ACCIDENTAL RELEASE MEASURES
CONTAINMENT:
No special precautions. Wear appropriate personal protection (See Section 8).
CLEAN-UP:
Use normal clean up procedures. 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. Wear appropriate protective equipment. 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. If already mixed with water, scrape up and place in container.
DISPOSAL:
Follow all local, state, provincial and federal regulations. Never discharge large releases directly into sewers or
surface waters. Slurry may plug drains. 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.
STORAGE:
Store in a cool, dry, ventilated area away from sources of heat, moisture and incompatibilities (see Section 10).
Dew point conditions or other conditions causing presence of liquid will harden this material during storage.
Protect product bags or containers from physical damage and weather.
Keep bags or other containers tightly closed to prevent moisture contact.

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 possible eye irritation.
Skin: 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.

CHRONIC EFFECTS / CARCINOGENICITY:
Crystalline silica: Testing of dust from USG plaster of paris has not detected respirable crystalline silica. 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. The weight percent of respirable crystalline silica has not been measured in
this product.
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).
