t HANDLING MEW FRICTION MATERIALS Handling new disc brake assemblies, lined brake shoes, clutch facings and brake blocks purchased in individual boxed seta is unlikely to create significant airborne concentrations of asbestos dust.

RECOMMENDED WORK PRACTICES FOR HANDLING ASBESTOS-CONTAINING FRICTION MATERIALS PRODUCED JM - 83 DRAFT - MARCH 13, 1978 INTRODUCTION The purpose of this booklet is to provide practical guidelines for brake and clutch service mechanics in the handling and processing of asbestos containing friction materials and in the maintenance and repair of brake and clutch assemblies on which the materials are.installed.

Two principles are important in designing dust control systems for particular operations: Duct sizes should be a minimum of 4 to 5 indies in diameter with air duct velocities of 4,000 to 4,500 feet per minute; and face velocities across the work station should be 200 to 250 feet per minute.
