Hot Work

1% of Non-roadway Fatalities*

Hot work activities are typically defined as those that create flames, heat and/or sparks. The most notable examples are welding, cutting, soldering, brazing and grinding. “Hot work,” however, also can include drilling, which creates heat due to friction, or the thawing of pipes. Hot work typically requires special work permits, especially when activities are being performed in areas where flammable atmospheres may exist. **
