    Title: Inspection Procedures

    • Employee exposure monitoring, including the collection of bulk samples
    • Engineering and work practice controls
    • Respiratory protection
    • Hazard communication
    • Symptoms of silicosis in workplace
    • Housekeeping and hygiene
    • Employee exposure and medical records
    • Abrasive blasting
    [Includes illustration of a man with a clipboard and the OSHA logo]

    Speaker Notes:

    --The minimum respiratory protection for workers exposed to crystalline silica during operations other than abrasive blasting is an N95 NIOSH-approved respirator for exposures that do not exceed the assigned protection factor.

    --Information regarding carcinogenicity must be included on labels and MSDSs

    --Bricks and crushed stone are covered by the Hazard Communication Standard (NOTE: some crushed stone operations fall under MSHA rather than OSHA.)

    --Other inspection issues for abrasive blasting operations include:
       Heavy metal exposure (lead, chromium, others)
       Exposure of other employees working in area
       Adequacy of ventilation systems
       Manual operation of blast cleaning nozzles
       Breathing air quality and use
       Electrical grounding
       Pressure controls
       Other adequate PPE
       Hazards of alternative abrasive materials
