Arc Flash Hazard Study
The purpose of an Arc Flash Hazard Study is to analyze the electrical distribution system and implement procedures that will minimize the risk of injury to a worker in the case of an arc flash incident.
Britton Electric is one of the very few electrical contractors who is capable of performing this vital service that includes analyses, equipment labelling and training.
Arc Flash Hazard Calculations
Before any testing and analysis can be done, a full inventory of the entire electrical distribution system is taken.
Depending on the different types of equipment that may be installed, decisions are made to determine the necessary processes to be followed.
Britton has the experience and expertise to adapt the Arc Flash Hazard Study to all types of electrical installations.
Protection Relay Coordination Analysis
Review current-time curve and single-line diagrams
Determine if the system conforms to health and safety regulations
Adjustment and calibration of protection relays
System Modelling and Analyses
To determine the level of risk the entire electrical system is first modelled, then short-circuit and incidental energy analyses are conducted. This is done to see how the system behaves and how much energy will be released in an arc flash event.
Calculations are made to determine the incident energy level, the arc flash hazard boundary and type and level of the Personal Protection Equipment (PPE) that must be worn at each location and corresponding to the specific hazard risk category.
Arc Flash Hazard Mitigation
Based on the analyses and calculation, each component of the electrical distribution system is labelled indicating the levels of risk, voltage and detailed safety information.
Training and Education
Explanation of all the different sections on the label
Instruction provided to workers on how to work safely and adhere to the required levels of protection
Reports, Recommendations and Corrective Measures
Reports and recommendations are prepared and presented
Implementation of corrective measures and required improvements are made to minimize risk of exposure to arc flash hazards
Findings are integrated into the client’s Health and Safety program
Compliance with: CNESST, CSA C22.10-18, CSA Z462-18, CSA Z463-18, IEEE 1584-2018, NFPA 70E-2018.
