Abstract: I have a few questions regarding the OSHA silica dust regulations:

  1. What is the proper disposal procedure for concrete dust we have collected in a vacuum cleaner (dust extractor)? Should full dust collection bags be placed in a special container, separate from a regular dumpster?
  2. What should be used to collect dust generated in constricted work areas where a dust suction attachment will not fit?
  3. If dust is coming into a work area from surrounding areas, how can it be distinguished from the dust generated by cutting or grinding operations?
  4. Can dust collection attachments from one manufacturer be used with tools from a different manufacturer?
  5. Is there a limit on length of a vacuum hose?
