When electrical hazards began to present themselves as one of the greatest threats to mining safety, the U.S. National Institute for Occupational Safety and Health (NIOSH), Office of Mine Safety and Health Research (OMSHR) conducted a study between 2000-2009. The study included three tasks:
The U.S. Bureau of Labor Statistics reported that 1,573 workplace fatalities between 2003 and 2009 had an electrical cause, and an estimated 18,260 nonfatal electrical injuries, resulting in days away from work, occurred over the same period.
The NIOSH, OMSHR study concluded that “There were 125,594 mining injuries reported to MSHA for 2000 through 2009, and Electrical was the 10th most frequently listed cause, with 853 injuries. Of the 853 mining electrical injuries for that period (those with the cause listed as Electrical), 39 were fatal, making electrical injuries the 6th most prevalent cause of death in mining.”
Of these injuries, 42% among them were electricians and mechanics. Contractor employees had a much greater chance of an electrical injury being fatal than did mine operator employees due to their unfamiliarity with the equipment and/or industry. Routine electrical and machine maintenance/repair activities were involved in 69% of electrical injuries. The investigators identified the top three root causes for fatal electrical injuries as:
In 2019, 3 electrical-related fatalities occurred that prompted Mine Safety and Health Administration (MSHA) to issue an alert on electrical hazards. According to MSHA, these fatalities occurred when:
As part of the alert issued by MSHA, the administration offered electrical safety best practices consisting of the following:
The MSHA alert’s best practices, while necessary to raise alarm, offered nothing new in terms of an employer’s and a qualified electrician’s responsibility when it comes to The Control of Hazardous Energy (OSHA 29 CFR 1910.147). This faithful reminder is simply a condensed and informal outline of the steps for performing LOTO. When LOTO is performed correctly, electrical hazards that may result in injuries or fatalities should be mitigated.
