Hazard statements

H317: May cause an allergic skin reaction. H370: Causes damage to organs. H372: Causes damage to organs through prolonged or repeated exposure. H: May form combustible dust concentrations in air.

2.3 Other hazards

Organic dust can form highly explosive mixtures when finely suspended in air. Avoid dust-laden atmospheres; minimize dust generation and accumulation. Eliminate sources of ignition, e.g. open flames, sparks or electrostatic discharge, or use explosion proof motors where needed.

Prevention

P241: Use explosion-proof electrical and ventilating equipment. P260: Do not breathe dust or vapors. P264: Wash hands and forearms thoroughly after handling. P270: Do not eat, drink or smoke when using this product. P272: Contaminated work clothing should not be allowed out of the workplace. P280: Wear protective gloves/protective clothing/eye protection/face protection. P281: Use personal protective equipment as required.

Response

P302+P352 IF ON SKIN Wash with plenty of water and soap P305+P351+P338 IF IN EYES Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. P308+P313 IF exposed or concerned Get medical advice/ attention P314: Get medical advice/attention if you feel unwell. P321 Specific treatment Wash affected areas immediately with plenty of water and soap P333+P313 If skin irritation or rash occurs Get medical advice/attention P362+P364: Take off contaminated clothing and wash it before reuse.

Storage

P405: Store locked up.

Disposal

P501: Dispose of contents and empty containers in accordance with local, regional and federal regulations. EMERGENCY OVERVIEW IMMEDIATE CONCERNS: HAZARD NOT OTHERWISE CLASSIFIED (HNOC) OR NOT COVERED BY GHS: Organic dust can form highly explosive mixtures when finely suspended in air. Avoid dust-laden atmospheres; minimize dust generation and accumulation. Routine housekeeping should be instituted to ensure that dust does not accumulate on surfaces. Dry powders can build up static electric charges when subjected to the friction of transfer and mixing operations. Implement adequate precautions, such as electrical grounding and bonding, or inert atmospheres. Eliminate all sources of ignition, e.g. open flames, sparks or electrostatic discharge, or use explosion proof motors where needed. Ensure that all areas where explosions could occur are designated appropriately. For recommendations to prevent such explosions and associated damage, consult applicable guidelines such as NFPA 68, "Standard on Explosion Protection by Deflagration Venting", NFPA 69, "Standard on Explosion Prevention Systems" and/ or NFPA 654, "Standard for the Prevention of Fire and Dust Explosions from the Manufacturing, Processing and Handling of Combustible Particulate Solids". For more information refer to Section #7 of this SDS.

Potential health effects

EYES: Contact may cause eye irritation. SKIN: Contact may cause allergic skin reactions. SKIN ABSORPTION: Skin absorption is unlikely to occur due to the physical form of the product. INGESTION: May be harmful if swallowed. INHALATION: Dust particles may cause respiratory tract irritation, coughing and wheezing. REPRODUCTIVE TOXICITY REPRODUCTIVE EFFECTS: Not known or believed to be a reproductive toxin.

Teratogenic Effects

Not known or believed to be teratogenic CARCINOGENICITY: No component of this product present at levels greater than or equal to 0.1% is identified as a carcinogen or potential carcinogen. MUTAGENICITY: Suspected of causing genetic defects.

Medical Conditions Generally Aggravated by Exposure

Asthma, Respiratory disorders, Skin Allergies, and Eczema

Principle Routes of Exposure

Inhalation, ingestion and through skin contact IRRITANCY: Dust particles have the potential to cause mechanical irritation of skin and eyes. SENSITIZATION: Contact may cause allergic skin reactions. COMMENTS: Refer to Section 11 for detailed information on health effects and symptoms. AS SOLD the product is a plastic molding compound: A plastic resin (polyester polymer) intimately mixed and reacted with one or more of a variety of organic and/or inorganic filling materials. The plastic resin is not believed or known to be hazardous. When fully “cured” or reacted, the plastic resin is insoluble, infusible and binds the well- dispersed, embedded filling materials. The great majority of filling materials are embedded within compound granules that are large enough not to constitute an inhalation hazard. Nevertheless, some particles of plastic resin and/or filling materials may be present in a size that constitutes a respirable dust (including, in some products, up to 1% inorganic filling material mixed in after compounding). This respirable dust may contain one or more of the following materials: crystalline silica, amorphous silica (diatomaceous earth), carbon black, fibrous glass, and/or wood flour (soft). Chronic inhalation of each of the above has been associated with fibrotic lung disease. For most or all, it has also been associated with increased risk of lung cancer, especially among smokers. Inhalation of dust should be avoidable with proper material handling procedures and good ventilation, but if not, Personal Protective Equipment (PPE) should be worn. The primary acute health risk from exposure to the product "As Sold" is irritation, especially from the dust. Ingestion, inhalation of dust, and contact with skin and eyes should be avoided. AS USED during polymerization (e.g., curing of the product during normal processing) no significant gaseous byproducts are expected. During decomposition (e.g., overheating or burning of the product) normal products of combustion would be expected. Grinding or machining of cured molded material may create a dust that poses a respiratory hazard if inhaled.
