The arc flash hazard analysis takes into account where in the system the fault occurs and how long the current exists before a protective device clears the fault. Therefore the protective device coordination needs to be investigated.

The amount of energy liberated during a fault can then be determined. All of these factors result in a specific calories-per-square-centimeter (cal/cm2) value of incident energy that is calculated for each point in the system.

This value indicates the level of personal protective equipment (PPE) that a worker must wear to safely perform any exposed energized work on the equipment.

This Electrical Safety Audit is comprised of a review of any existing Electrical Safety Program documentation (or other supporting documents), onsite interviews (Electrician’s interview typically takes 1.5 hours and Manager/Supervisor interview takes 1 hour), and observations (both facility inspections and work task (if the opportunity is available).

The context of the Electrical Safety Audit will be to assess the status of existing use of Electrical Specific PPE, Electrical Safe Work Procedures and Electrical Safety & Technical Training as it pertains to managing electrical hazards and minimizing exposure to workers when they must complete exposed energized electrical work.

Consistency with NFPA 70E, Standard for Electrical Safety in the Workplace and industry accepted best practices will be measured.

The review and audit services provided will include the provision of an Audit Team, combined with support from appropriate Company staff in a supporting role.

Most companies now realize that it is not sufficient to implement a generic, “one size fits all” energy plan. For an effective response, with respect to maintaining the energy management system, such a plan must be customized to fit to a company.

A more difficult task is the compilation of an implementation plan that balances the requirements of the standard, the business needs and the certification deadline  

"The goal for any organization should be to reduce energy consumption and spend through methods of improved energy efficiency and energy management. Through the process of thorough Investigative Data Analysis, companies are quickly able to identify where cost savings can be made and energy saved. Sometimes the outcome of IDA is astonishing, revealing energy saving opportunities not previously prominent on the radar”

“Using energy efficiently helps organizations save money as well as helping to conserve resources and tackle climate change”

Very high system currents are developed in the system due to resistance drop in the event of a short circuit fault and cloud discharge in the event of a lightning strike respectively.

It can cause irreversible damages to an installation, facility or life.

Appropriate interconnected Earthing System in coordination with lightning design must be in place to allow clearing path for these fault or unwanted currents.

It is seen that in the design of new installations these two aspects are considered but with the aging and loading effects the designs of past either don’t hold to the rated requirements and latest regulations,

Or unwarranted maintenance of lightning rods, earth pits, down conductors, earthing rods etc. as well as change in soil properties over time leads to an unsure and unsafe situation to Utility Services Manager, Operation Heads and workers. However it’s recommended that checking on Earthing and Lightning design at facilities should be the regular activity in the standard operating procedures for a better workplace safety and efficient operations.
