Course Introduction

Welding, cutting, and brazing are hazardous activities which pose a unique combination of both chemical and physical hazards to more than 560,000 workers in a wide variety of industries. The risk from fatal injuries alone is more than four deaths per thousand workers throughout a working lifetime.

There are numerous health hazards associated with exposure to fumes, gases, and ionizing radiation generated during welding, cutting, and brazing. These hazards include heavy metal poisoning, lung cancer, metal fume fever, flash burns, and many others. The risks associated with these hazards vary depending upon the type of welding materials and welding surfaces.

Real-Life Accident

In 2008, a welder installed a flow regulator on a cylinder of carbon dioxide, which was the shielding gas for the metal inert gas (MIG) welder he was using to prevent exposure of the molten weld pool to oxygen, nitrogen and hydrogen contained in the air atmosphere. The welder felt a shock from the MIG welder and asked a coworker to see if he could feel it. The coworker refused and went back to his work area. Shortly thereafter, the coworker heard a yell from the welder and saw him holding the ground clamp in one hand and the electrode holder in the other hand. Another coworker unplugged the welder. Once the MIG welder was unplugged, the welder fell to the floor. A co-worker performed CPR on the welder until rescue personnel arrived. The welder was transported by ambulance to Buchanan County General Hospital, where he was pronounced dead from electrocution.

This course introduces the student to the hazards and safety precautions related to welding, cutting, brazing, and soldering. The course discusses general welding operations, applicable OSHA standards, and suggestions for protecting welders and coworkers from exposures to the many hazards inherent in those operations.

The course discusses the various types of welding operations, as well as exposure to thermal and chemical hazards and precautions including the personal protective equipment required to mitigate those hazards.
