Market: US/CanadaUSG Fiberock Aqua-Tough Tile Backerboard is a unique, fiber-reinforced gypsum product that represents a new era in substrate performance for wet or dry areas, as recognized within the TCNA Handbook and International Residential Code. This durable panel offers superior performance and tile bond in addition to an integral water-resistant core. Unlike traditional water-resistant gypsum board, FIBEROCK Aqua-Tough tile backerboard derives both strength and water-resistance from its uniform composition. Made of a uniquely engineered gypsum/cellulose-fiber combination, it is strong, water resistant, and mold resistant, scoring a 10, the highest possible rating on ASTM D 3273. With no paper face to delaminate, tear, or scratch, it maintains its integrity, even when wet.
Purpose of product.
Usage: Cementboard underlayment for tilesStructure such as solid, liquid, aerosol etc.

Chemical Composition/Ingredients
The GHS is an acronym for The Globally Harmonized System of Classification and Labelling of Chemicals. The GHS is a system for standardizing and harmonizing the classification and labelling of chemicals. Chemicals are associated with codes that define their health, physical and environmental hazards.This universal hazard communication system was developed to ensure that employers, employees and consumers are provided with adequate, practical, reliable and comprehensible information on the hazards of chemicals, so that they can take effective preventive and protective measure for their own health and safety.

The GHS classifications for chemicals associated with products in this database may be viewed by selecting the "Advanced" button on the Chemical Ingredients tables. Since this is a work in progress, GHS classifications may not be shown for all chemical ingredients.-
Primary Chemical Name is the standard name assigned to a chemical substance.
ChemicalChemical Abstracts Service Registry Number is a unique identifier for a chemical and its synonyms. CAS numbers identify the chemical, but not its concentration or specific mixture. CAS Registry Numbers are assigned by the Chemical Abstracts Service, a division of the American Chemical Society. For more information: www.cas.org

Warnings
Dust can be corrosive to eyes, skin, and respiratory tract. Contact can cause severe chemical burns. Avoid breathing dust. Dust can contain silica. Prolonged and repeated breathing of silica dust can cause lung damage and/or cancer. Wear eye, skin and respiratory protection as necessary per working conditions. If eye contact occurs flush immediately with water for 30 minutes. Do not ingest. If ingested, call physician. If cutting board with a power tool, use a wet or vacuum saw to reduce the amount of dust generated. Panels are heavy and can fall over, causing serious injury or death. Avoid creating a tripping hazard and do not exceed floor limit loads. Dust can contain silica. Prolonged and repeated breathing of silica dust can cause lung damage and/or cancer.

Acute health effects
From MSDS:
Hazard Identification
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. This product does 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. This product contains quartz (crystalline silica) as a naturally occurring contaminant.
Potential Health Effects
Primary Routes of Entry: Inhalation, eyes and skin contact.
Inhalation: Exposure to dust generated during the handling or use of the product may cause temporary irritation to 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.
Eye contact: Dust can cause temporary mechanical irritation of eyes. If burning, redness, itching, pain or other symptoms persist or develop, consult physician.
Skin: None known.
Ingestion: None known.
Medical conditions that 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.

Chronic health effects
From MSDS:
Inhalation: The concentration of respirable crystalline silica measured in bulk samples of USG gypsum was less than 0.1 Wt.%. Industrial hygiene testing, following the NIOSH Method 7500, did not detect respirable crystalline silica in dust created during the cutting of USG gypsum wallboard panels by both the recommended score and snap technique and with the use of a power saw in a 10ft by 10ft room.
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.
Eye contact: None known.
Skin contact: None known.
Ingestion: None known.

Handling information
Handling: Avoid dust contact with eyes and skin. Wear the appropriate eye and skin protection against dust. Minimize dust generation and accumulation. Avoid breathing dust. Wear the appropriate respiratory protection against dust in poorly ventilated areas and if TLV is exceeded. 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’ extends beyond the supports on either end.
Follow traditional building practices; such as management of water away from 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.
Gypsum panels are very heavy awkward loads posing the risk of severe back injury. Use proper lifting techniques.
Store in a cool, dry, ventilated area away from sources of heat, moisture and incompatibilities. Protect product from physical damage. Protect from weather and prevent exposure to sustained moisture.
Gypsum Association literature recommends storing board flat to avoid damaging edges, warping the board and 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. If stacking board vertically, leave at least 4 inches from the wall to decrease the risk of falling board and no more than 6 inches to avoid too much lateral weight against the wall.

First Aid
Inhalation: Remove to fresh air. Leave the area of exposure and remain away until coughing and other symptoms subside. Other measures are usually not necessary, however if conditions warrant, contact physician.
Eye contact: In case of contact, do not rub or scratch your eyes. To prevent mechanical irritation, flush thoroughly with water for 15 minutes. If irritation persists, consult physician.
Skin
Wash with mild soap and water. If irritation persists, consult physician.
Ingestion: This product is not intended to be ingested or eaten. If gastric disturbance occurs, call physician.
Notes to Physician: Treatment should be directed at the control of symptoms and the clinical condition.
