However, the possibility still remains that at tlmas whan meincanance or repair work la performed on Instruments containing asbestos soma exposure could occur. Abrasive action to the insulation block such aa craping or brushing could causa airborne generation of fiber*. For thl* reason, it ia racooaanded that ell unit* containing esbeatoa be adequately aealed.
