2 2 This product can release nuisance dust in handling or during use. Eye, skin, nose, throat, and upper respiratory irritation may occur with prolonged dust exposures. Effects of Overexposure: Acute: Eyes Direct Contact can cause mechanical irritation of eyes. If burning, redness, itching, pain or other symptoms persist or develop, consult a physician. Chronic: Eyes: This material hardens and slowly becomes hot when mixed with water. Therefore, it SHOULD NOT be used to make a cast enclosing any part of the body. 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 and rubbing against the skin can result in abrasions. Rinse with water until free of material to avoid abrasions, then wash skin thoroughly with mild soap and water. May dry skin. Inhalation of dusts from this product may irritate the nose, throat, lungs, and upper respiratory tract. Persons subject 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. Unlikely to occur, but may cause gastric disturbances if swallowed. 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 Emergency and First Aid Ingestion below. Gypsum plaster displays no specific toxic properties. Prolonged and repeated exposure to respirable crystalline silica can result inlung disease (i.e. silicosis) and /or lung cancer. None known None known No known effects Carcinogenicity: Material IARC NTP Crystalline silica (Group 1) Anticipated In 1997, IARC classified inhaled crystalline silica as a carcinogenic to humans categorizing it as a Group 1 agent. In this evaluation, IARC noted that carcinogenicity was not detected in all industrial circumstances studied, and may be dependent on inherent characteristics of the crystalline silica or on external factors affecting its biological activity or distribution of its polymorphs. In 1992, NTP listed respirable crystalline silica among the substances reasonably anticipated to be carcinogens.

3 3 Emergency First-Aid Procedures: Eyes: Target Organs: Medical Conditions Aggravated: Primary Routes of Entry: Flush thoroughly with water for 15 minutes. If irritation persists, consult physician. Wash with mild soap and water. Dry skin may be treated with a commercially available hand lotion. If skin has become cracked, take appropriate action to prevent infection and promote healing. Leave the area of dust exposure and remain away until coughing and other symptoms subside. While other measures are usually not necessary, consult a physician if conditions warrant. No specific recommendations. If gastric disturbance occurs, consult physician. This product contains gypsum plaster. Plaster of Paris hardens when wetted and, if ingested may result in obstruction of the gut, especially the pyloric region. Eyes, skin and respiratory system Pre existing upper respiratory and lung diseases such as, but not limited to Which may be bronchitis, emphysema, and asthma. Inhalation, eyes and/ or skin contact. Precautionary Labeling: HMIS NFPA Health 0 0 Flammability 0 0 Reactivity 0 0 Other - N/A Rating Scale: 0=Minimal Hazard, 1=Slight Hazard, 3=Serious Hazard, 4=Extreme Hazard Precautionary Label Statements: Caution, may cause irritation during use. Avoid contact with eyes, skin, and clothing. Wash thoroughly after handling. When not in use, keep in tightly closed container. Section VI Reactivity Data Stability: Hazardous Polymerization: Conditions to Avoid: Incompatibles: Stable Will Not Occur None Acids

4 4 Decomposition Products: Above 1,450 C could produce CaO and SO 2 Section VII Spill and Disposal Procedures Steps to be taken in the event of a spill or discharge: Remove by dry-sweeping or vacuum. Avoid creating excessive dust. Do not wash down drains since it could plug drains. Wear protective equipment. Disposal Procedure: Dispose of material in accordance with all applicable federal, state and local regulations. Section VIII Special Protection Information No TLV assigned to this mixture, see Ingredients Section. Minimize exposures in accordance with good hygiene practice. Ventilation: Respiratory Protection: Personal Protection: Equipment: Ventilate to keep exposures below TLV requirements of the individual ingredients. General ventilation is expected to be satisfactory. Use local exhaust ventilation if necessary to control dust. None required where adequate ventilation conditions exist. In order to meet TLV requirements of individual ingredients and to control dusting conditions, provide general ventilation and local exhaust ventilation. Avoid creating dust. Wear a NIOSH/MSHAapproved dust respirator in poorly ventilated areas and/or if TLV requirements of the individual ingredients is exceeded. While not necessary, gloves and/ or protective clothing may be desireable in certain working conditions, such as repeated or prolonged skin contact. Wear eye protection (safety glasses Gloves are not required, but may be desirable under certain working conditions or to protect against drying of hands. Section IX Special Precautions Precautions to be taken in handling and storage: Wear appropriate protective equipment during handling and store in a dry area to minimize potential for clumping due to moisture absorption. Dew point conditions or other conditions causing presence of moisture will harden gypsum during storage.
