Section III - Hazard Identification
Routes of Exposure: Desert Crete Base can affect the body if it is inhaled, ingested, or
comes in contact with the eyes and skin.
Summary of Acute Health Hazards
Inhalation: Crystalline silica can cause silicosis, a progressive and frequently
incapacitation pneumoconiosis evident on x-ray and in pulmonary function testing, as
well as in subjective respiratory complaints.
Skin: May cause skin irritation.
Eyes: May be slightly irritating to eyes, hold eyelids open and flush with plenty of water.
If irritation persists, GET MEDICAL ATTENTION.
Summary of Chronic Health Hazards: N/A
Signs and Symptoms of Exposure: Undue breathlessness, wheezing, cough, and sputum
Effects of Overexposure: Crystalline silica can cause silicosis, a progressive and
frequently incapacitating pneumoconiosis evident on x-ray and in pulmonary function
testing, as well as in subjective respiratory complaints.
Medical Conditions Generally Aggravated by Exposure: Pulmonary function may be
reduced by inhalation of respirable crystalline silica. Also lung scarring produced by such
inhalation may lead to a progressive massive fibrosis of the lung which may aggravate
other pulmonary conditions and diseases and which increases susceptibility to pulmonary

tuberculosis. Progressive massive fibrosis may be accompanied by right heart
enlargement, heart failure, and pulmonary failure. Smoking aggravates the effects of
Note to Physicians: N/A
Section IV - First Aid Measures
Inhalation: Remove victim to fresh air and administer artificial respiration if required.
GET MEDICAL ATTENTION, if needed.
Skin: Flush skin with plenty of water. If rash develops, get medical attention.
Eyes: Immediately flush with plenty of water for at least 15 minutes. GET MEDICAL
ATTENTION, if discomfort persists.
