When released into the atmosphere, flammable gases, vapors from flammable liquids, and combustible dusts may be ignited if an ignition source is present. A Hazardous Area Classification (HAC) study is the required analysis for minimizing the likelihood of ignition of flammable material while considering gas/vapor/combustible dust sources and ignition design controls. Refinery, chemical, and related industries depend on accurate HAC documentation and drawings to determine the proper type of electrical equipment permitted in their facilities.
We combine the knowledge and experience of world class experts in HAC with our patented HACTool© program to apply the applicable HAC methodologies addressed by NFPA, API, CSA, and the IEC to produce an evergreen 3-D model for hazardous area classification. Our unique approach to HAC goes beyond the industry standard for unit boundary limit area classifications to address important details in boundary extents and ignition source gaps.
BakerRisk’s methodology to HAC is more than the typical “check box” study performed to meet regulatory requirements. HACTool© output provides an evergreen product that continues to generate value and cost savings in capital expenditures over the life of a facility. While HAC drawings are often created as part of the facility design package, many of the details are not well-documented. To save money on analysis, plant designers often choose to use conservative assumptions such as drawing the boundaries at the battery limits of the unit and not considering the height component of classified areas. This conservative approach often requires higher rated equipment than what would otherwise be prescribed by the appropriate standards, and results in increased capital expenditures during construction as well as continuous additional operational expenditures over the life of the facility.
BakerRisk’s HAC methodology provides the following key advantages:
- Structured semi-automated process
- Easy verification of criteria
- Easy to update
- HAC plan view and 3D views
- HAC contours match equipment
- Consistent application of HAC standards
- GAP reporting well defined
- HACTool© provides detailed study documentation
- Facilitates MOC work with details on gaps
