If You Work in an Area Where These Are Present:
Then Use This Type of Forklift.
Hazard Classification

Class II

  • Combustible dust is present
Division I Explosive or conductive mixture may be present under normal conditions or where equipment failure can lead to both this condition and arcing or sparking. Division II Explosive mixture not normally present but where deposits of dust may cause heat rise in electrical equipment
