SECTION 2: Hazards identification
Physical hazards
Not classified The hazards below apply to dust generated from handling or processing. Inhalation: Acute (immediate) - Dusts may irritate the nose, throat and respiratory tract by mechanical abrasion and drying. Coughing, sneezing, shortness of breath may occur. Inhalation: Chronic - Long term exposure to crystalline silica may cause a chronic lung disease, silicosis. Respirable Crystalline Silica (RCS) may cause cancer. Limestone is a naturally occurring mineral complex that contains varying quantities of quartz (crystalline silica). In its natural bulk state, limestone is not a known
Health hazards
Limestone may be subjected to various natural or mechanical forces that produce small particles (dust) which may contain RCS (Respirable crystalline silica particles less than 10 micrometers in aerodynamic diameter). Repeated inhalation of RCS (quartz) may cause lung cancer according to IARC and NTP; ACGIH® states that it is a suspected cause of cancer. Other forms of RCS (e.g., tridymite and cristobalite) may also be present or formed under certain industrial processes. Continued Eye contact: Acute - Dust particles can scratch the eye causing tearing, redness, a stinging or burning feeling, or swelling of the eyes with blurred vision. Chronic – no known effects. Skin contact: Acute - Dust particles can scratch and irritate the skin with redness, and itching or burning feeling, swelling or the skin, and / or rash. Chronic – no known effects. Ingestion: Expected to be practically non-toxic. Acute - Ingestion of large amounts may cause gastrointestinal irritation including nausea, vomiting, diarrhea, and blockage. Chronic – no known effects.

Precautionary statements
Do not handle until all safety precautions have been read and understood ▪ Respiration protection: NIOSH-MSHA approved dust respirators for conditions where dust levels may exceed exposure limits. Ventilation: As required to maintain exposures below PEL’s, REL’s and TLV®’s. Vent dust to collector. Eye protection: Dust goggles should be worn when visibly dusty conditions exist.
Storage
Restrict or control access to stockpile areas. Engulfment hazard To prevent burial or suffocation, do not enter a confined space, such as a silo, bulk truck or other storage container or vessel that stores or contains aggregates without an effective procedure for assuring safety.
Disposal
Dispose of contents/container in accordance with any and all applicable federal, state, and local laws, regulations, and practices.
