EMERGENCY OVERVIEW: WARNING! Injurious to eyes. When mixed with water, this
material hardens and then slowly becomes hot. DO NOT attempt to make a
cast enclosing any part of the body using this material. Failure to follow
these instructions may cause severe burns that may require surgical removal
of affected tissues. May cause eye and skin irritation. Avoid skin and eye
contact. Removal of this product after use will result in the generation of
dust. If dry-sanded, exposure to dust may result in build-up of material in
eyes, ears, nose, and mouth which may cause irritation.
EFFECTS OF OVEREXPOSURE - EYE CONTACT: May cause eye irritation.
EFFECTS OF OVEREXPOSURE - SKIN CONTACT: May dry skin. May develop
enough heat to cause burns if a large mass such as a cast of hand or arm,
is kept in contact with skin while hardening.
EFFECTS OF OVEREXPOSURE - INHALATION: Exposure to dust may cause
irritation to nose, throat, and respiratory system.
EFFECTS OF OVEREXPOSURE - INGESTION: : Irritating to mouth, throat, and
stomach. Ingestion may result in obstruction when wetted plaster hardens.
EFFECTS OF OVER EXPOSURE - CHRONIC HAZARDS
The International Agency for Research on Cancer (IARC)has determined that
crystalline silica in the form of quartz or cristobalite that is inhaled
from occupational sources is carcinogenic to humans (Group 1รป carcinogenic
to humans). Refer to IARC Monograph 68, Silica, Some Silicates and Organic
Fibres (published in June 1997) in conjunction with the use of these
materials. The National Toxicology Program (NTP) classifies respirable
crystalline silica as known to be a human carcinogen. Refer to the 9th
Report on Carcinogens (2000). The American Conference of Governmental
Industrial Hygienists (ACGIH) classifies crystalline silica, quartz, as a
suspected human carcinogen (A2).
Breathing dust containing respirable crystalline silica may not cause
noticeable injury or illness even though permanent lung damage may be
occurring. Inhalation of dust may have the following serious chronic health
effects: Excessive inhalation of respirable dust can cause pneumoconiosis,
a respiratory disease, which can result in delayed, progressive, disabling
and sometimes fatal lung injury. Symptoms include cough, shortness of
breath, wheezing, non-specific chest illness and reduced pulmonary
function. Smoking exacerbates this disease. Individuals with pneumoconiosis
are predisposed to develop tuberculosis. There is some evidence that
breathing respirable crystalline silica or the disease silicosis is
associated with an increased incidence of significant disease endpoints
such as scleroderma (an immune system disorder manifested by fibrosis of
