What does OSHA require employers to do about airborne hazards?

While requirements vary by contaminant and industry, OSHA generally requires employers to provide a workplace free from recognized hazards and maintain exposures below established permissible exposure limits (PELs) for certain substances. Managing dust, fumes and mist can support OSHA compliance, reduce liability and improve worker health and safety. Employers should also consider ventilation, engineering controls and housekeeping practices to reduce risk.
