SECTION 3 HAZARD IDENTIFICATION (continued)
POTENTIAL HEALTH EFFECTS
ACUTE:
Eyes: Airborne dust or direct contact can irritate or burn eyes. The extent of damage depends on duration of contact.
Rapid response is very important to prevent significant damage to the eye (See Section 4, First Aid Measures).
Portland cement can cause burns and cornea damage that may result in permanent damage with risk of blindness.
Contact lenses should not be worn when working with portland cement.
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.
Contact with wet portland cement can cause severe irritation, redness, rash, and/or chemical burns, including third
degree burns. Burns may occur 12 or 48 hours after exposure. Burns may occur without obvious pain at the time of
exposure.
Exposure to dry portland cement may cause drying of the skin with consequent mild irritation or more significant
effects attributable to aggravation of other conditions. Dry portland cement contacting wet skin or exposure to moist or
wet portland cement may cause more severe skin effects including thickening, cracking or fissuring of the skin.
Prolonged exposure can cause severe skin damage in the form of (caustic) chemical burns.
Discomfort or pain cannot be relied upon to alert a person to a hazardous skin exposure. Consequently, the only
effective means of avoiding skin injury or illness involves minimizing skin contact, particularly contact with wet cement.
Exposed individuals may not feel discomfort until hours after the exposure has ended and significant injury has
occurred.
Some individuals may exhibit an allergic response upon exposure to portland cement, possibly due to trace amounts
of chromium. The response may manifest in different forms ranging from a mild rash to severe skin ulcers. Individuals
already sensitized may react to the first contact with the product. Other individuals may experience a response after
years of contact with portland cement products.
Inhalation: Inhalation of portland cement dust can irritate or burn the nose, throat, and mucous membrane of the
upper respiratory tract. Signs of excessive exposure to this dust include shortness of breath and reduced pulmonary
function. If respiratory symptoms persist, consult physician.
Ingestion: Portland cement can cause chemical burns to the mouth, throat, esophagus and stomach. Can cause a
burning sensation in mouth and stomach. Pain and nausea can occur if a sufficient amount is ingested. In severe
cases gastrointestinal bleeding or perforation of the esophageal or stomach lining may develop. The effects due to
ingestion can be delayed and occur days later. 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.
Bronchitis and emphysema may occur from prolonged portland cement dust inhalation.
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 may be aggravated by dust exposures. Pre-existing skin
diseases such as, but not limited to, rashes, dermatitis. Unusual hypersensitivity to hexavalent chromium
(chromium+6) salts. Some individuals may exhibit an allergic response to portland cement, possibly due to trace
amounts of chromium. The response may appear in a variety of forms ranging from a mild rash to severe skin ulcers.
Sensitized individuals may react immediately upon contact and others may first experience this effect after years of
contact with portland cement products.
Notes to Physician: Treatment should be directed at the control of symptoms and the clinical condition. Treatment
should be directed at the control of symptoms and the clinical condition. Skin irritation may occur hours or days after
the time of portland cement exposure. The main types of skin reactions seen are dermatitis of the hands, forearms,
and feet seborrheic eczema, stasis dermatitis, and, occasionally exfoliative dermatitis.

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.

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 safety glasses with side shields or goggles for eye protection to avoid irritation and severe chemical
burns of the eye.
Contact lenses should not be worn when working with portland cement.
Skin: Wear gloves, long-sleeved shirts and pants to prevent skin contact. Wear eye protection. Barrier creams may
be applied to face, neck, wrist and hands when skin is exposed to help prevent drying of skin. Do not rely on barrier
creams for the only skin protection or use in place of gloves.
General: Selection of Personal Protective Equipment will depend on environmental working conditions and
operations.

SECTION 11 TOXICOLOGICAL INFORMATION (continued)
CHRONIC EFFECTS / CARCINOGENICITY (continued):
Crystalline silica (continued): 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).
Portland cement: NIOSH conducted a portland cement worker study, 鈥淭he Mortality of U.S. Portland Cement and
Quarry Workers鈥?, March 1985, which found 鈥淭here is no excess mortality from all causes of death, lung cancer, non-
malignant respiratory disease, or ischemic heart disease鈥? among the workers studied.
SECTION 12
ECOLOGICAL INFORMATION
ENVIRONMENTAL TOXICITY: Portland cement is expected to be toxic to fish due to its high alkalinity (pH > 12).
