work" is defined as riveting, welding, burning or other fire- or
spark-producing operations. This section covers all hot work
operations except for those requirements found in Confined and
Enclosed Spaces and Other Dangerous Atmospheres in Shipyard
Employment. Sparks or molten metal from hot work, when combined
with oxygen and a fuel source, can start a fire. Hot work is
only allowed in areas that are free of fire hazards, or where
fire hazards have been controlled by physical isolation, fire
