HAZARD IDENTIFICATION
EMERGENCY OVERVIEW:
螖WARNING!
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.
POTENTIAL HEALTH EFFECTS (See Section 11 for more information)
ACUTE :
Exposure to dust generated during the handling or use 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
Inhalation 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.
Dust can cause mechanical irritation of eyes. If burning, redness, itching, pain or other symptoms
Eyes
persist or develop, consult physician.

ACCIDENTAL RELEASE MEASURES
CONTAINMENT: Collect panels from spillage and if not damaged or contaminated by foreign material, panels may be
reclaimed.
CLEAN-UP: Use normal clean up procedures. No special precautions.
DISPOSAL: Follow all local, state, provincial and federal regulations. Never discharge large releases directly into
sewers or surface waters.
SECTION 7
HANDLING AND STORAGE
MATERIAL SAFETY DATA SHEET MSDS #14-CGC-DUR
Page 4 of 9
DUROCK庐 Brand Cement Boards
HANDLING: Avoid dust contact with eyes. Wear the appropriate eye protection against dust (See Section 8).
Minimize dust generation and accumulation. Avoid breathing dust. Wear the appropriate respiratory protection
against dust in poorly ventilated areas and if TLV is exceeded (see Sections 2 and 8). 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.
Cement panels are very heavy awkward loads posing the risk of severe back injury. Use proper lifting techniques.
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.
Storing board flat will prevent 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.

*ACGIH: 1 fiber/cubic centimeter air for fibers longer than 5 micrometers and thinner than 3 micrometers.
ENGINEERING CONTROLS: Provide ventilation sufficient to control airborne dust levels. If user operations generate
airborne dust, use ventilation to keep dust concentrations below permissible exposure limits. Where general
ventilation is inadequate, use process enclosures, local exhaust ventilation, or other engineering controls to control
dust levels below permissible exposure limits.
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. If
engineering controls are not possible, wear a properly fitted NIOSH/MSHA-approved particulate respirator.
OTHER PERSONAL PROTECTIVE EQUIPMENT:

CHRONIC EFFECTS / CARCINOGENICITY:
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 may not have 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).

OTHER INFORMATION
Label Information
螖 WARNING!
Portland cement is strongly alkaline. Direct contact can be corrosive and cause severe damage or chemical burns to
the eyes and wet or moist skin. Avoid contact with eyes and skin. Wear eye protection, alkali-resistant protective
gloves, long-sleeved shirts and pants to prevent direct contact. If eye contact occurs, immediately flush thoroughly
with water for 30 minutes and seek medical advice. Inhalation of dust may be corrosive or cause chemical burns or
irritation to nose, throat and respiratory tract. Avoid breathing dust. Use in a well-ventilated area or provide sufficient
local ventilation. If dusty, wear a NIOSH/MSHA-approved dust respirator. Wash thoroughly with soap and water after
use. Do not ingest. If ingested, call physician. Panels are heavy and can fall over, causing serious injury or death.
Avoid creating a tripping hazard and do not exceed floor limit loads. Long-term breathing of respirable crystalline
silica dust can cause permanent lung damage and/or cancer. If cutting board with a power tool, use a wet or vacuum
saw to reduce the amount of dust generated. Product safety information: (800) 507-8899 or www.cgcinc.com.
