Emergency Overview
PermaBase?BRAND Cement Board Products do not present an inhalation, ingestion, or contact health
hazard unless subjected to operations such as sawing, sanding or machining which result in the
generation of airborne particulate. Dust generated is alkaline, and could cause corrosive damage to skin,
tissues, and eyes. Wear eye and skin protection. This product also contains quartz (crystalline silica) as a
naturally occurring contaminant. It is recommended that a NIOSH approved particulate respirator be worn
whenever working with this product results in airborne dust exposure exceeding the prescribed limits.
(See Section 11 - Toxicological Information)
OSHA Regulatory Status
While this material is not considered hazardous by the OSHA Hazard Communication Standard (29CFR
1910.1200), this MSDS contains valuable information critical to the safe handling and proper use of the
product. This MSDS should be retained and available for employees and other users of this product.

2. HAZARDS IDENTIFICATION (CONTINUED)
Potential Health Effects
Primary Routes of Entry: Inhalation, Dermal contact
Target Organs: Respiratory system, skin, eyes.
Inhalation: Acute exposure to airborne dust concentrations in excess of the PEL/TLV may result in
coughing, dyspnea, wheezing, and a burning irritation of the nose, throat, and upper respiratory tract,
along with possible impaired pulmonary function. Chronic exposures may result in lung disease (silicosis
and/or lung cancer). (See Section 11 - Toxicological Information)
Exposures to respirable crystalline silica have not been documented during normal use of this product.
However, good housekeeping practices and industrial hygiene monitoring is recommended when the
potential for significant exposure exists.
Skin Contact: Contact with wet portland cement may cause severe irritation, redness, and possible burns.
Continued and prolonged contact may result in drying of the skin. Contact with dust or glass fibers may
produce itching, rash and/or redness. Repeated or prolonged exposure may result in dermatitis.
Eye Contact: Contact with dust may cause burns and/or mechanical irritation. Do not wear contact lenses
if dust will be generated.
Ingestion: Wet product is alkaline, and may cause chemical burns to the mouth, throat, esophagus and
stomach. Gastrointestinal irritation or bleeding may develop.

4. FIRST AID MEASURES
Inhalation: Remove exposed individual to fresh air immediately. If breathing difficulty persists, seek
medical attention.
Skin: Flush and wash skin with soap and water. Utilize lotions to alleviate dryness if present. Seek
medical attention if irritation persists.
Eye: Do not rub or scratch eyes. Immediately flush eyes with water for 15 minutes. Seek medical
attention to evaluate for burns or scratches.
Ingestion: Product is not intended to be ingested. Large amounts may cause abdominal discomfort
or possible obstruction of the digestive tract. Seek medical attention if problems persist.

6. ACCIDENTAL RELEASE MEASURES
Not applicable, as product is an article composite.
General recommendations:
Wear appropriate Personal Protective Equipment. (See Section 8)
Maintain proper ventilation.
Pick-up larger pieces to avoid a tripping hazard. Sweep or vacuum remaining material into a waste
container for disposal. Use a light water spray to minimize dust generation.
Waste material is not a hazardous waste. Dispose of in accordance with applicable federal, state,
and local regulations.
7. HANDLING AND STORAGE
Avoid contact with eyes, skin and clothing.
Wear recommended personal protective equipment when handling. (See Section 8)
Avoid breathing dust.
Minimize generation of dust.
Utilize proper lifting techniques when moving product and employ mechanical/ergonomic assistance
when possible (i.e. move with forklifts, hold in place with lifts) to minimize the risk of back injury.
Store material in a cool, dry, ventilated area, away from excessive heat or sunlight.
Store panels flat to minimize damage.
Do not stack panels too high when storing to minimize the risk of falling.

Engineering Controls
Work/Hygiene Practices: The score and snap method of cutting is recommended. Sawing, drilling or
machining will produce dust.
Ventilation: Provide local and general exhaust ventilation to maintain a dust level below the PEL/TLV.
Utilize wet methods, when appropriate, to reduce generation of dust.
Personal Protective Equipment
Respiratory Protection: A NIOSH approved particulate respirator is recommended in poorly ventilated
areas or if the PEL/TLV is exceeded. OSHA's 29 CFR 1910.134 (Respiratory Protection Standard)
must be followed whenever work conditions require respirator use.
Eye Protection: Safety glasses or goggles.
Skin: Gloves, protective clothing and/or barrier creams may be utilized if conditions warrant.

11. TOXICOLOGICAL INFORMATION
Human Data
There is no information on toxicokinetics, metabolism and distribution.
There have been reports of irritation and burns to mucus membranes of the eyes and respiratory tract
upon acute exposure to dusts in excess of the recommended limits.
Chronic exposure to crystalline silica (a naturally occurring contaminant) in the respirable size has been
shown to cause silicosis, a debilitating lung disease. In addition, the International Agency for Research on
Cancer (IARC) classifies crystalline silica inhaled in the form of quartz or cristobalite from occupational
sources as carcinogenic to humans, Group 1. The National Toxicology Program (NTP) classifies
respirable crystalline silica as a substance which may be reasonably anticipated to be a carcinogen.
OSHA does not regulate crystalline silica as a human carcinogen. Industrial hygiene monitoring to date
has not identified any detectable respirable crystalline silica in dust sampling conducted during gypsum
panel installation utilizing recommended procedures.
Animal Data
LD50 and LC50 data not available.
12. ECOLOGICAL INFORMATION
This product could be toxic to fish due to its high alkalinity from the portland cement. No studies are
available.
