Fire and Explosion Data Flash Point: Not flammable Flammable Limits in Air: Not flammable Extinguishing Agents: None required Unusual Fire and Explosion Hazards: Bentonite is not explosive, will not support combustion 5. Reactivity Data Stability: Stable Incompatibility with other substances: N/A 6. Toxicity and First Aid Unless specified otherwise, limits are expressed as eight-hour time-weighted averages (TWA) Respirable Crystalline Silica (quartz): MSHA-Proposed and OSHA-Proposed PEL = 0.1 mg/m3 Total Dust: MSHA = 30 mg/m3 divided by (%SiO2 + 3) MSHA, ACGEH, and OSHA have determined that adverse effects are not likely to occur in the workplace provided exposure levels do not exceed the appropriate TLVs/PELs. However, because of the wide variation in individual susceptibility, lower exposure limits may be appropriate for some individuals including persons with pre-existing medical conditions such as those listed below. Medical Conditions Aggravated by Exposure Inhaling respirable dust and/or crystalline silica may aggravate existing respiratory system disease(s) and /or dysfunctions. Exposure to dust may aggravate existing skin and/or eye conditions. Primary Routes(s) of Exposure Inhalation Skin Ingestion Acute Toxicity Eye Contact: Direct contact with dust may cause irritation by mechanical abrasion. Skin Contact: Direct contact may cause irritation by mechanical abrasion Skin Absorption: Not expected to be a significant exposure route. Ingestion: Expected to be practically non-toxic. Inhalation: Dusts may irritate the nose, throat, and respiratory tract by mechanical abrasion. First Aid Eyes: Immediately flush eye(s) with plenty of clean water for at least 15 minutes, while holding the eyelids open. Skin: Wash with soap and water Ingestion: N/A Inhalation: Remove to fresh air. Dust in throat and nasal passages should clear spontaneously. Contact physician if irritation persists. 7. Personal Protection and Controls Respiratory Protection: Use a NIOSH approved respirator Skin Protection: Wash dust-exposed skin with soap and water before eating and drinking. Wash work clothes after each use. Eye protection: Safety glasses with side shields should be worn as minimum protection. Dust goggles should be worn when excessively dusty conditions are present.
