Section 4. First Aid Measures
Inhalation
Acute effects – Dust may cause irritation of the nose, throat and
airways, resulting in coughing and sneezing. Certain susceptible
individuals may experience wheezing (spasms of the bronchial
airways) upon inhaling dust during cutting, rebating, drilling, routing,
sawing, crushing or otherwise abrading fiber cement, and when
cleaning up, disposing of or moving the dust.
Chronic effects – Repeated or prolonged over exposures to
crystalline silica can cause silicosis (scarring of the lung) and
increases the risk of bronchitis, tuberculosis, lung cancer, renal
disease, and scleroderma (a disease affecting the connective tissue
of the skin, joints, blood vessels, and internal organs.) Some studies
suggest that cigarette smoking increases the risk of silicosis,
bronchitis and lung cancer in persons also exposed to crystalline
silica.
Acute silicosis – A sub-chronic disease associated with acute,
massive silica exposure, is a rapidly progressive, incurable lung
disease that is typically fatal. Symptoms include, but are not limited
to, shortness of breath, cough, fever, weight loss and chest pain.
Such exposure may cause pneumoconiosis and pulmonary fibrosis.
Required treatment – If inhalation of dust occurs, remove to fresh
air. If shortness of breath or wheezing develops, seek medical
attention.
Skin
Dust may cause irritation of the skin from friction but cannot be
absorbed through intact skin.
If skin contact occurs, wash with mild soap and water. Contact
physician if irritation persists or later develops.
Eyes
Dust may irritate the eyes from mechanical abrasion causing
watering or redness.
If eye contact occurs, remove contact lenses (if applicable). Flush
with running water or saline for at least 15 minutes. Seek medical
attention if redness persists or if visual changes occur.
Ingestion
Ingestion is unlikely under normal conditions of use, but swallowing
the dust from the product may result in irritation or damage to the
mouth and gastrointestinal tract due to alkalinity of dust.
If ingestion occurs, dilute by drinking large amounts of water. Do
