' The intent is to vise manufacturers and fabricators, who use asbestos frictio n m aterials, of VJork Practices best suited to maintaining a working environment within the levels required by 1910.93a. of the OSHA Standards (copy attached). 1. Asbestos Friction M aterial Products covered, by this work practice recommendation: 1.1 Clutch Facings 1.2 Brake Lining Segments 1.3 Brake Slocks 1.1 Disc 3 rake Pads 1.5 Brake Band Materials 1.6 Automatic Transmission Discs 2. Operations to which the recommended work practices ray apply: 2.1 Clutch Assembly and P.ebuilding Operations 2.2 Brake Assembly and Relining Operations 2.3 Automatic Transmission Assembly ana Rebuilding-Operations3. Requirements of OSiiA 1910.93^. -3.1 The Asbestos Standard (1910.93a) applies to any manufacturing, fabrication or handling process or operations /involving articles or materials composed wholly or in part o f asbestos fib re. 3.2 I t is the employer' s responsibility to maintain "Exposure to airborne concen tration of asbestos fibres" at or below the levels described in 1910.93a.. 'Exposure levels may be controlled by isolation , enclosure, exhaust ventilation and dust co lle ctio n . Standard 1910.93a. does not lim it the means used to maintain compliance. 3.3 Particular tools - A ll hand or power operated tools which may cause the release of asbestos fibre to become airborne at levels in excess of the standard shall be provided with exhaust ventilation. 3.L V.'et Methods - 'When practicable asbestos products sh a ll be processed -wetted su fficien tly to prevent emission of dust to the atmosphere. (Limited cr not required where wetting would reduce end e ffic ie n c y o f the product.) 3.5 Protective Equipment and Clothing - Vih"never i t is necessary for employees to perform*their normal work in an environment where airborne concentration of asbestcs'fibre exceeds the allowable level of Standard 191C.93&, the employer must provide respiratory protection and clothing in compliance with the standard. The employer must also provide change rooms and separate lechers for work clothes and street cloth.es. 3.6 Air Sanding and Monitoring - The employer is responsible as described in 1910.932.. ^7 *. { J - W A ----- be stored in sealed containers. Handling or asoej ' shall be cone in a earner to minimize generation of airborne asbestos dust. 3 .c Caution Signs and Labels - The employer shall use caution signs and labels --^ in accordance with provision of Standard 1910.93a. U. Exhaust and Dust Collection Systems 1.1 V.nerever exhaust ar.d dust collection systems are used to attain concentrat ions c; airborne asbestos fibre belov/ the levels allowed in Standard 1910.93a, the systems shall be inspected and cleaned at least weekly. 1.2 lesiGn, in sta lla tio n and maintenance of exhaust and dust collection systems shall be in accordance with American National Standard Fundamentals Govern ing Design and Operation c f Local Exhaust Systems (ANSI 29.2) or equivalent 5"XcJIC2-I*Q. e Housekeeping in .'Manufacturing and Fabrication Areas: 5.1 All surfaces, machinery, equipment, etc. shall be kept free o f accumulation of asbestos dust, preferably by vacuum cleaning or other method that w ill prevent asbestos dust or fibre from becoming airborne. Vacuum cleaners should be equipped with a disposable collection bag ard a micro f ilt e r . 5.2 '/aste and scrap m aterial, such as dust, chips, o ff-cu ts, edge trimmings and broken pieces sh all be placed in sealed containers in preparation for disposal. 5.3 Containers used to store or dispose of asbestos-containing materials sh all be labeled in a manner to comply with Standard 1910.93s- i . Reco--ended Procedures for manufacturing and 'abrication Operations Involving Asbestos Friction Materials: 6.1 ' "nsrever fe a sib le , frictio n materials that are specially treated to reduce dust emission should be used. 6.: Materials should be removed from containers gently and handled.with care to avoid unnecessary generation o f airborne .dust. Care should be taken not to disturb dust remaining in containers and packaging m aterials. Ouch dust should be removed by vacuum cleaning wherever fe a sib le . t- n hr.srever fe a sib le , materials should be obtained from the manufacturer cut, machined and/or d rille d to suit fin al requirements to avoid necessity for additional fabrication operations. c.i. Cr. large volume operations with fixed working points or machines, lo c a l exhaust systems should be installed ir. accordance with American National Duancard A .'ll Z9-.2 or equivalent standard. *L*/z hr.er. cutting, d r illin g , grinding or machining operations are of short duration, portable dust exhaust units may be suitable. .Vacuum cleaning equipment, some times may be adapted for this purpose, provided the f ilt e r system is of cccuc.ic ci ficier, cy, t '6.6 the v.-ork . 1X1 suppress! 6.7 6. 3 I f surfac wising wi attaohner.
