SECTION IV - FIRE AND EXPLOSION HAZARD DATA

Flash Point, Method: N/A / UEL: N/A / LEL: N/A
Extinguishing Media: / Use media appropriate for surrounding fire.
Special Fire Fighting Procedures: / Fire fighters should wear full protective clothing and self contained breathing apparatus.
Unusual Fire and Explosion Hazards: / Not combustible. Excessive dust generation creates a potential explosion hazard.

SECTION V - REACTIVITY DATA

Stability: Stable / Conditions to Avoid: N/A
Incompatibilities (Materials to avoid): / Acids, Chlorinated Phenols + Potassium Nitrate, Moler Anhydride, Nitroparaffins and Phosphorus.
Hazardous Decomposition Products: / None expected
Hazardous Polymerization: / Will not occur.

SECTION VI - HEALTH HAZARD DATA

Carcinogenicity: / Not listed as a carcinogen by NTP, IARC, or OSHA.
Routes of Entry: / Inhalation, Skin and Eye Contact (if handled in such a manner that dust is generated.)
Effects of Overexposure: / This material is a mildly caustic irritant. Overexposure may cause irritation of the eyes, skin, mucous membranes and respiratory system. Contact with skin may cause dermatitis.
Excessive long term exposure to crystalline silica via the respiratory route has been associated with a fibrotic lung disease called silicosis. Silicosis may be disabling and is sometimes fatal. Signs and symptoms of silicosis include coughing, wheezing, shortness of breath, impairment of pulmonary function, and chest pain. Amorphous silica does not cause silicosis, and may be treated as nuisance dust.
Limestone is not listed on the NTP, IARC, or OSHA lists of carcinogens. Crystalline silica, a component of this product, is listed by IARC but not by NTP or OSHA. IARC has determined that there is sufficient evidence for carcinogenicity to experimental animals exposed to crystalline silica and limited evidence for carcinogenicity to humans. “Limited evidence” means that a causal relationship is possible, however, other explanations such as chance, bias or confounding factors cannot adequately be excluded. NTP has proposed (1989) to list crystalline silica based on the IARC determination.
Medical Conditions Aggravated by Exposure: / Chronic disease and disorders of the respiratory system and skin.

SECTION VII - FIRST AID AND MEDICAL EMERGENCY PROCEDURES

Eye Contact: / Flush with large amounts of water for at least 15 minutes, while rolling eyeball and lifting eyelid. Get medical attention.
Skin Contact: / Wash affected area with mild soap and water. Get medical attention.
Inhalation: / Remove from exposure. Restore (artificial respiration) and support (administer oxygen) breathing as necessary. Get medical attention.
Ingestion: / Give milk, egg whites or water to drink. DO NOT induce vomiting. Get medical attention.

SECTION VIII - OCCUPATIONAL EXPOSURE CONTROL MEASURES

Engineering Controls (Ventilation, etc.): / Ventilation should be sufficient to maintain dust levels below the applicable exposure limit for nuisance dust and calcium hydroxide.
Eye Protection: / Safety glasses or goggles are recommended when eye contact is possible. Eyewash stations are also recommended if eye contact is possible.
Skin Protection: / Gloves and long-sleeve clothing are recommended when dust levels are excessive.
Respiratory Protection: / When engineering controls are not sufficient to lower dust levels below the applicable exposure limit, use a NIOSH-approved half-mask respirator equipped with a dust filter within the use limits of the respirator.
Work Practices (Handling and Storage, etc.): / Use good housekeeping. Avoid creating airborne dust by wetting or other dust suppression methods. Avoid inhalation of dust. Avoid eye and skin contact. Wash after contact, before smoking, eating, and drinking.

SECTION IX - SPILL, LEAK AND DISPOSAL INFORMATION

Procedures to Follow if Material is Released or Spilled: / Don protective equipment. Scoop up, with sweep or vacuum. Material should be placed into a DOT approved container.
Waste Disposal Method(s): / Any excess product can be recycled for further use or disposed by methods which are in accordance with local, state and federal regulations.
