5. HAZARD IDENTIFICATION
POTENTIAL HEALTH EFFECTS:
NOTE: Potential health effects may vary depending upon the
duration and degree of exposure. To reduce or eliminate health
hazards associated with this product, use exposure controls or
personal protection methods as described in Section 12.
EYE CONTACT:
(Acute/Chronic) Exposure to airborne dust may cause immediate
or delayed irritation or inflammation of the cornea. Eye contact by
larger amounts of dry powder or splashes of wet Concrete Mix
may cause effects ranging from moderate eye irritation to chemical
burns and blindness.
SKIN CONTACT:
(Acute) Exposure to dry Concrete Mix may cause drying of the
skin with consequent mild irritation or more significant effects
attributable to aggravation of other conditions. Discomfort or pain
cannot be relied upon to alert a person to a hazardous skin
exposure.
(Chronic) Dry Concrete Mix coming in contact with wet skin or
exposure to wet Concrete Mix may cause more severe skin effects,
including thickening, cracking or fissuring of the skin. Prolonged
exposure can cause severe skin damage in the form of chemical
(caustic) burns.
(Acute/Chronic) Some individuals may exhibit an allergic response
upon exposure to Concrete Mix. The response may appear in a
variety of forms ranging from a mild rash to severe skin ulcers.
INHALATION:
(Acute) Exposure to Concrete Mix may cause irritation to the
moist mucous membranes of the nose, throat and upper respiratory
system. Pre-existing upper respiratory and lung diseases may be
aggravated by inhalation.
(Chronic) Inhalation exposure to free crystalline silica may cause
delayed lung injury including silicosis, a disabling and potentially
fatal lung disease, and/or cause or aggravate other lung diseases or
conditions.
INGESTION:
(Acute/Chronic) Internal discomfort or ill effects are possible if
large quantities are swallowed.
CARCINOGENIC POTENTIAL:
Concrete Mix is not recognized as a carcinogen by NTP, OSHA, or
IARC. However, it may contain trace amounts of heavy metals
recognized as carcinogens by these organizations. In addition, it
also contains crystalline silica which IARC classifies as a known
human carcinogen (Group I). The NTP, in it’s ninth Annual Report
on Carcinogens, classified “silica, crystalline (respirable)” as a
known carcinogen. (See also Sections 4 and 12.)
