ArcPro Software

ArcPro software was developed by Ontario Hydro to calculate the thermal parameters of electrical arcs. The program is designed to aid in the selection of protective clothing by defining the potential arc hazard for workers who may be accidentally exposed to electrical arcs. The user can then specify clothing that will withstand the level of predicted arc hazards. The system has a colorful, user-friendly interface and an extensive clothing database including various weights and fabrics. The software allows you to save different scenarios and also lets you use your own ignition data. ArcPro software is available in the US from HD Electric at (847)473-4980.

Brooklawn National Lab Fire Hazard Analysis

Comprehensively and qualitatively assess the risk from fire within the National Synchrotron Light Source (NSL) to ensure Department of Energy (DOE) fire safety objectives are met.

Cooper-Bussman's Arc Flash Calculator

The values returned by the online ArcFlash Calculator can help in determining the appropriate level of Personal Protective Equipment (PPE) and where the arcflash protection boundary lies. These are areas of major concern when analyzing electrical safety for personnel and the ArcFlash Calculator can aid in determining necessary precautions.

Duke Power's Heat Flux Calculator

This freeware is offered with no claims from ArcWear.com, Hoagland Consulting or Duke Power to help you assess your potential for electrical arc. This DOS program will give you the predicted incident energy in cal/cm. You can then get assistance from OSHA or a company offering arc thermal performance value (ATPV) data on their clothing in choosing your clothing

You will need to enter the following data once you have downloaded the program:

  • amps of ground fault available,
  • expected duration of the arc in cycles,
  • expected length of the arc,
  • distance of the worker from the arc and system voltage

National Institute of Standards & Technology Fire Hazard Analysis Techniques

The goal of fire hazards analysis (FHA) is to determine the expected outcome of specific set of conditions called a fire scenario. The scenario includes details of the room dimensions, contents and materials of construction; arrangement of rooms in the building; air; position of doors and other details that have an effect on the outcome of interest.
