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
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.
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
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.
