Arc Flash Injures 2 in FL, Shuts Down Cogen Facility

Indiantown, FL – Two workers have been injured in an electrical arc flash accident and fire at the Indiantown Cogeneration Facility in Martin County, Florida. The incident occurred in a motor control center around 8:40 a.m. Both workers were hospelectrical arc flashitalized for injuries incurred during the arc flash and resulting fire.

The facility is out of service while officials investigate the equipment to determine the cause of the electrical arc flash.

An Arc Flash is an electrical explosion due to a fault condition or short circuit when either a phase to ground or phase to phase conductor is connected and current flows through the air. Arc flashes cause electrical equipment to explode, resulting in injury or death to workers and destruction of electrical equipment.

Temperatures may exceed 35,000° F (the surface of the sun is 9000° F). These high temperatures cause rapid heating of surrounding air and extreme pressures, resulting in an arc blast. The arc flash / blast will likely vaporize all solid copper conductors which will expand up to 67,000 times its original volume when it is vaporized. The arc flash / blast produces fire, intense light, pressure waves and produces flying shrapnel.

There are a variety of reasons why an Arc Flash can occur, but most of them are human error and preventable. Many arc flashes occur when maintenance workers are manipulating live equipment for testing or repair and accidentally cause a fault or short circuit. Improper tools, improper electrical equipment, corrosion of equipment, improper work techniques and lack of electrical safety training are just some of the events that can lead to a devastating arc flash or arc blast.

When an arc flash happens, it does so without warning and is lightning quick. The result of this violent event is usually destruction of the equipment involved, fire, and severe injury or death to any nearby people. Proper safety and protection measures must be taken to limit the damage from an arc flash which include conducting an arc flash study, short circuit study, and NFPA 70E electrical safety training.

Understanding arc flash compliance is often complicated. OSHA mandates that employers identify electrical hazards, warn employees about the hazards and provide them proper protection and training regarding the hazards. While OSHA tells you “what to do” for arc flash, they don’t tell you “how” to do it. The role of NFPA 70E, IEEE 1584 and NEC is to provide guidance on “how” to properly implement the OSHA regulations.

After Electrical Fire in England, Business Owner says: “We’ve Lost Everything.”

Cotgrave, Nottinghamshire, England – An electrical fire in an industrial building in the East Midlands of England has devastated at least three area businesses. Investigators have found the blaze which tore through an industrial estate last week was caused by an electrical fire.

The fire severely damaged the large two-story building which housed six separate units. There were no reports of any injuries. Businesses on the estate included a dry cleaner, steeplejack, and a plastics firm.

Nottinghamshire Fire and Rescue Service station manager Tom Clark stated: “We can now conclude that the fire was an electrical fire caused by one of the manufacturing processes in the building.” “There were also a couple of gas cylinders involved and there was a kerosene tank of 400 litres which needed protecting in the next building,” a fire spokesman said. Although no one could predict this fire from happening, it could have been prevented if the appropriate electric checks were carried out. Businesses should regularly have all of their electrical appliances and outlets checked and can opt to Learn more about their electrics from their electrician. That way, they can spot any faults and call out an electrician immediately to resolve the issue.

Many Cotgrave residents were out on the streets following the explosion, which sent a black smoke ring into the sky as smoke billowed from the buildings. Fire crews spent several hours tackling the inferno, which destroyed six units at the site.

Ray Hallam, owner of TVR Steeplejacks, saw his livelihood ruined as he surveyed the devastating scene – and said he had lost “literally everything.” The office where the renovations and repairs company was based has been completely gutted by the fire, destroying equipment, files and computers. The 65-year-old, who has run the family business for 15 years, said: “I’ve had to lay people off this morning because of this. I’ve had to contact customers because we’ve lost all our equipment, which was between £50,000 and £100,000-worth. It’s very upsetting.”

Other businesses affected by the blaze include Impressive Ironing and Cleaning Services and taxi firm DJM. Kirsty MacDonald, who set up Impressive four years ago and moved into the industrial site a year ago, said she was heartbroken. The 32-year-old, of Cotgrave, said: “That’s my livelihood gone, people’s jobs gone. We’ve lost everything. I was just in shock. After four years of effort to get it to where it was, for it to come to this was devastating…Everything’s just been blown apart.”

NY Paper Worker Fatally Burned, International Paper on Severe Violators List

Essex County, New York – An employee of a Ticonderoga (NY) area paper mill was fatally burned in January 2015. Jorg Borowski, 57 years old, was caught in a flash fire while servicing air pollution equipment and died of his burns a day later. Owners of the International Paper Company have been faulted for numerous serious safety violations and face up to $210,000 in fines.

International Paper has been added to a special OSHA’s Severe Violator Enforcement Program, aimed at companies that “have demonstrated indifference to (safety regulations) by willful, repeated, or failure-to-abate violations.” OSHA linked the company’s failure to conduct annual safety inspections of the “fly ash bag house” where Borowski was working to identical violations at its plants in Chicago and Newark, Ohio, in 2011.

In citations filed by OSHA this week, the IP mill in Ticonderoga was faulted for not providing Borowski with fire-resistant protective clothing, for improper maintenance of fly ash pollution control equipment so that it introduced oxygen needed for the fire to ignite and for not having an automatic fire control system where Borowski was working to remove and replace burned, smoldering filter bags of combustible fly ash.

The system for collecting fly ash also failed to meet National Fire Protection Association standards and had been inadequately maintained, according to OSHA.

“This worker’s death was preventable. International Paper knew of these hazards and deficiencies and did not address them,” said Kim Castillon, OSHA’s area director in Albany. “While nothing can return this man to his daughter and co-workers, the company can and must take prompt and effective steps to ensure that this never happens again.”
