Periodic examinations of urine should not exceed 0.5-1.0 mg arsenic/liter of urine
\ Preclude from exposure those individuals with diseases of blood, liver, kidney, and central nervous system
ASBESTOS
Synonyms: Amianthus - Amphibole Chrysotile Earth Flax Impure Magnesium-calcium Silicate Mountain Cork Serpen tine Stone Flax Many mineralogical names
Description: Flax-like fibers; fireproof Occupational Exposure:
Clutch facings and brake linings Roofing and insulating materials Asbestos cloth products, valve packings, gaskets, pipe cover
ing Auto undercoatings Threshold Limit Value: 5 million particles/cu ft of air Toxicity: Arsorption; Inhalation Pathology:
Asbestos warts, from fibers that penetrate epidermis Pulmonary interstitial fibrosis via mechanical action
of long fibers (20-50 microns) in terminal bron chioles
Grade I: Asbestos bodies in alveoli Grade II: Asbestos bodies * Thickening of alveolar
walls Perivascular fibrosis Grade III: Coarse honey-combing of lungs Scar
ring in upper portions * Thickening of Pleura Adhesions Benign asbestos pleurisy may occur without other significant pulmonary disease Signs and Symptoms: Anorexia Cough * Dyspnea Loss of weight Pallor Weakness - Cyanosis Clubbed fingers Decreased vital capacity

ASBESTOS
38
Diagnostic Tests:
,
Asbestos bodies in sputum
X-ray changes after 10 years or more of exposure:
Stage I: Increased density at both bases with an occasional superimposed granular pat
tern Apices dear Stage II: Decrease in clarity of cardiac silhouette Densities extend to the periphery of mid
dle and lower thirds of both lung fields
--"ground glass appearance" Accentuation of hilar markings Stage III: Shadowing of middle and lower thirds of
both lung fields Cardiac shadow obscured--"shaggy
heart"
Treatment:
Symptomatic and supportive
Disability: Disease ceases to progress on cessation of exposure
Question of cancer not yet answered
Preventive Measures: Adequate ventilation Wet methods * Mechanical filter
respirator Physical examinations of exposed personnel annually, in
cluding vital capacity measurements and chest x-rays
Preclude from exposure: Persons with pulmonary disease Persons under 40 when diagnosis of asbestosis is definite Persons in whom disease is progressing, regardless of age
