C. RECOMMENDED CONTROL PRO-
CEDURES To prevents exposure to high concentrations of amorphous amorphous silica dust process ventilation and enclosure are the best means of control For some operations dust respirator
approved by the U. Bureau of Mines jay be satisfactory IV Spectic Procedures
A. FIRST AID None
B. SPECIAL MEDICAL PROCEDURES
1 Preplacement Clinical and chest radiographic examinations should be made on all persons prior to job nssignment
2 ) Periodie Since there is only lim
ited information about the harmful
effects of amorphous silica in industry exposed personnel should have careful periodic medical ex-
aminations including chest ray Pulmonary function testing may be
useful
3 Treatment No satisfactory treat-
ment other than removal from ex-
posure and therapy for any complicating infection
