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.

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 NIOSHapproved 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.
