Guidelines
  • OSHA recommends maintaining gas concentrations below the Lower Explosive Limit to prevent explosion hazards and ensure proper ventilation in the workspace. Regularly monitor gas levels using detectors to avoid risks associated with explosive concentrations.
Health Effects
  • LEL is a measure of explosivity, not directly toxic. Exposure to gases near LEL can lead to explosion hazards, and in confined spaces, it could cause asphyxiation or injury if ignited.
