According to OSHA, arc flash burns are one of the top three most common hazards when working with energized electrical equipment.
Every day in the U.S. there are up to 10 arc flash incidents, totaling more than 3,600 disabling electrical contact injuries each year. The violent nature of arc flash exposure, which can result in a fatality, even if a worker is 10 feet from the blast site.
OSHA cited ASARCO – a metal smelting company – for electrical hazards after an arc flash caused three workers to suffer severe burns at its facility in Hayden, Arizona. The company faces $278,456 in penalties for two willful violations and one serious violation.
Arc eye, or welder’s flash, is an inflammation of the cornea, caused by the UV rays from the arc during welding. The symptoms, which appear a few hours to several hours after exposure, can include mild to severe pain, red watery eyes, sensitivity to light and the feeling of a foreign object in the eye. Typically, arc eye is temporary, but repeated or prolonged exposure can lead to permanent eye injury.
“Welding fumes are a complex mixture of fine condensed metallic particulate and other solid particles. While welding fume is not a gas, some gases such as ozone, NOx and carbon monoxide are also generated during the welding process,” says Keith Daley, environmental systems manager at The Lincoln Electric Company of Canada.
Welding helmets protect you from UV radiation, particles, debris, hot slag and chemical burns. It’s important that you wear the right lens shade for the work you are carrying out. Follow the manufacturer’s guidelines and gradually adjust the lens filter until you have good visibility that does not irritate your eyes.
Welding fumes inhaled through the years may cause serious medical complications. Those noises that didn't seem so loud actually were, potentially destroying your ability to hear. The parts that didn't seem so heavy may trigger shoulder problems. The constant kneeling can lead to knee troubles.
Welding operators should always wear an approved respirator unless exposure assessments are below applicable exposure limits.
Report concerns to a supervisor so your exposure to substances of the welding fumes can be checked.
Electric shock is one of the most serious and immediate risks facing a welder. Electric shock occurs when welders touch two metal objects that have a voltage between them, inserting themselves into the electrical circuit.
The most common type of electric shock is secondary voltage shock from an arc welding circuit, which ranges from 20 to 100 volts.
In a unanimous decision, a three-judge panel of the U.S. Ninth Circuit Court of Appeals ruled Monday that Exxon Mobil Oil Corp. must produce information to the U.S. Chemical Safety Board (CSB) related to a tank filled with hydrofluoric acid at the site of a 2015 oil refinery explosion in Torrance, California.
The decision reverses a lower Court ruling that the information was not sufficiently relevant to the CSB’s investigation.
An initiative underway in Denver, Colorado may provide a blueprint for other U.S. cities who want to improve safety on their roadways for “vulnerable” road users - bicyclists, pedestrians, and motorcyclists. Denver Vision Zero is a five-year plan crafted by city agencies and State and community partners that includes improved street design, safe speeds, a culture of safety, and improved data.
