Arc Flash Risk Assessment

 

THOMPSON KNOWS ARC FLASH

Under the Occupational Safety and Health Act of 1970, employers are responsible for providing safe workplaces for their employees and onsite contractors. In April 2014 OSHA added new rules covering electrical hazards and safety.  OSHA specifically added new requirements to protect workers from electric arcs.  Beginning in April 2014 all employers were required to label their electrical equipment so as to identify the incident energy potential, the proper NFPA PPE to be worn, and approach-distance requirements to better ensure that unprotected workers do not get dangerously close to energized equipment. 


“What is an Arc Flash?”  is often one of the first questions asked so let’s start there. An Arc Flash is a dangerous condition associated with an electrical explosion or the release of energy caused by an electrical arc.  The flash causes an explosion with temperatures up to 35,000-degrees F, dangerous pressure and sound waves, thermal radiation, and shrapnel. This can cause serious damage to your personnel and facility, lengthy downtime, and expensive regulatory fines.  An Arc Flash Risk Assessment is required by OSHA and can be used to determine:  

  • Flash Protection Boundaries 
  • Incident Energy Value 
  • Proper Hazard Categorization of equipment 
  • Appropriate Personal Protective Equipment NFPA PPE
  • Arc Flash Risk Mitigation

WHY SHOULD I HAVE AN ARC FLASH RISK ASSESSMENT?
  1. OSHA General Duty Clause which states: Each employer shall furnish to each of his employees employment and  a place of employment which are free from recognized hazards that are  causing or are likely to cause death or serious physical harm.  
  2. OSHA 29 CFR 1926.960(g) 
    1. Hazard assessment. The employer shall assess the workplace to identify employees exposed to hazards from flames or from electric arcs.  
    2. Estimate of available heat energy. For each employee exposed to hazards from electric arcs, the employer shall make a reasonable estimate of the incident heat energy to which the employee would be exposed.
  3. OSHA 29 CFR 1910.335 Employees working in areas where potential electrical hazards exist shall be provided with and shall use personal protective equipment. 
  4. NFPA 70e 110.  A The employer shall implement and document an overall electrical safety program that directs activity appropriate to the risk associated with electric hazards. The electrical safety program shall be implemented as apart of the employer’s overall occupational health and safety  management system, when one exists.
