Potential Health Effects
Relevant Routes of Exposure:
Eye contact, skin contact, inhalation, and ingestion.
Effects Resulting from Eye Contact:
Exposure to airborne dust may cause immediate or delayed irritationor inflammation. Eyecontact by large amounts of dry powder
or splashes of wet limestone dust may cause effects ranging from moderate eye irritation to chemical burns or blindness. Such
exposures may require immediate first aid (see Section 4) and medical attention to prevent damage to the eye.
Effects Resulting from Skin Contact:
Direct contact may cause irritation by mechanical abrasion.
Effects Resulting from Inhalation:
Limestone may contain trace amounts of free crystalline silica. Prolonged exposure to respirable free silica can aggravate other
lung conditions and cause silicosis, a disabling and potentially fatal lung disease.
Exposure to limestone dust may causeirritation to the moist mucous membranes of the nose, throat, and upper respiratorysystem.
It may also leave unpleasant deposits in the nose.
Effects Resulting from Ingestion:
Although small quantities of dust are not known to be harmful, ill effects are possible if larger quantities are consumed.
Carcinogenic potential:
Limestone is not listed as a carcinogen by NTP, OSHA, or IARC. It may however, contain trace amounts of substances listed as
carcinogens by these organizations.
