Hazardous Area Classification

EngWorks specializes in the hazardous area classification design of facilities handling flammable gases, liquids and facilities handling combustible dusts.  Our goal is to ensure that the area classification design is appropriate for the hazard that may exist.  This allows you to determine the appropriate operating procedures and level of equipment protection required to achieve  a safe working environment.

All our designs are fully documented, allowing you to easily maintain the area classification design over the life of the facility.  Each area classification design will include the following:

• Hazardous Area Classification design drawings
• Area Classification details
• Summary report incorporating:
  • Flammable gas/vapour/liquids mixture analysis
  • Combustible dust analysis
  • Source of release worksheets
  • Fugitive emission analysis
  • Adequate ventilation design calculations
  • HVAC design parameters
  • Purged and pressurized building design
  • Design requirements for vapor barrier systems separating classified from unclassified areas
  • Infrared sensing and gas quantification analysis
  • Criteria for locating LFL gas detectors
    
    

We are experienced in both the Division and the Zone methods of area classification and can help you determine what approach provides the maximum benefit to your facility.
