Exposure of eyes to wet stucco mix may cause chemical burns and blindness.
Exposure to airborne dust can cause immediate or delayed irritation or
inflammation.

through ingestion
May be harmful if ingested.
through inhalation
Dust generated during handling this stucco concentrate may cause irritation to
the respiratory tract.
Exposure of skin to wet stucco mix may cause chemical burns. Symptoms of
exposure may take several hours to manifest.
on the skin
on the eye
Dangerous decomposition products:
Will not spontaneously occur. Addition of water will produce caustic calcium hydroxide, which can cause chemical burns.

None known
Some items mentioned in Section 8 are considered mineral dusts by OSHA and a
correctly fitted, NIOSH approved respirator is required when working with this
product.
mineral dusts
A single, short term exposure to the dry form of these two items, which are
present in this stucco concentrate mix, are not likely to cause serious harm.
However, exposure of sufficient duration to wet stucco can cause serious,
potentially irreversible tissue destruction of the skin or eye from caustic
chemical burns, including third degree burns. The same type of tissue
destruction can occur if wet or moist areas of the body are exposed for
sufficient duration to dry stucco concentrate. Wet stucco is causstic and
personal protectove equipment, and proper work hygiene, must be employed
for protection against personal injury.
portland cement and calcium hydroxide

crystalline silica (quartz, christobalite)
Primary irritant effect:
Stability and reactivity
Considered a known human carcinogen by Federal (OSHA) and advising health
agencies (IARC, NIOSH, and NTP). Additionally, crystalline silica can cause a lung
condition known as silicosis after long term exposure to dusts containing
crystalline silica. Exposure of workers to crystalline silica containing dusts is
specifically regulated by OSHA. The use of a correctly fitted, NIOSH approved
respirator suitable for use against crystalline silica inhalation is essential for
minimizing exposure to this danger.
Acute toxicity:
None known
