EMERGENCY OVERVIEW: Portland cement is a nuisance dust. However, portland cement is strongly alkaline and can
cause severe injury. If user operations generate dust, contact with eyes or skin can cause irritation and possible
irreversible tissue damage, corrosion damage, chemical burning and corneal damage. Wear eye and skin protection.
Particulate will also cause mechanical irritation. Inhalation of dust can cause severe upper respiratory irritation. If user
operations generate dust, contact lenses should not be worn.

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. If user
operations generate dust, contact lenses should not be worn.
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. Avoid dust exposures generated during when cutting dried product.
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.
CHRONIC:
Eyes: None known.
Skin: None known.
Ingestion: No known effects.
Inhalation: Panels do not release respirable dust in their installed state and therefore do not present any known health
hazards when installed and properly maintained.
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.
Bronchitis and emphysema may occur from prolonged portland cement dust inhalation.
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. Immediately flush thoroughly with lots of water including
flushing under upper and lower eyelids for at least 15 minutes. Get medical attention. An eye examination should be
performed. It may take 48 to 72 hours after the exposure to adequately assess extent of damage..
Skin: Flush exposed skin with copious amounts of water for at least 15 minutes depending on concentration, amount
and duration of exposure. Wash with mild soap and water. Immediately remove all contaminated clothing, including
footwear. Launder clothing before reuse. If irritation or pain persists get medical attention immediately. A commercially
available hand lotion may be used to treat dry skin areas. If skin is cracked, take appropriate action to prevent infection
and promote healing. If irritation persists, consult physician. 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.
Inhalation: Remove to fresh air. Leave the area of dust exposure and remain away until coughing and other symptoms
subside. If conditions warrant, contact physician.
Ingestion: This product is not intended to be ingested or eaten. 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. 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.

SECTION 7
HANDLING AND STORAGE
HANDLING:
When cutting or installing board, minimize the generation and accumulation of dust. 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).
Cement panels are very heavy awkward loads posing the risk of severe back injury. Use proper lifting techniques.
If user operations generate dust, contact lenses should not be worn.
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.
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). 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. If user operations generate dust, contact lenses should not be worn.
Skin: Wear gloves, long-sleeved shirts and pants to prevent repeated or prolonged skin contact. 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.

CHRONIC EFFECTS / CARCINOGENICITY:
Crystalline silica: Panels do not release respirable dust in their installed state and therefore do not present any known
health hazards when installed and properly maintained.
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).
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).
