Conference & Expo

Hot work accidents occur throughout many industries in
the United States, including food processing, pulp and
paper manufacturing, oil production, fuel storage, and
waste treatment. Most hot work incidents occur due to
the ignition of combustible materials (e.g., a roofing fire)
or the ignition of structures or debris near the hot work
activity. Although the hazards associated with hot work
are well documented, the frequency and severity of hot

CONSEQUENCES
Hot work was blamed for a
2014 fire in Boston that killed
two firefighters. The event
helped spur a hot work safety
training program developed by
NFPA (see facing page).

work-related incidents have been overwhelming in the
last two decades. In order to fully benefit from the lessons
learned from these incidents, it is important that industry
and safety organizations adopt more stringent health and
safety standards to ensure that hot work activity is conducted safely, that workers are aware of the hazards, and
that they are fully protected.
The U.S. Chemical Safety and Hazard Investigation Board
(CSB) has found that hot work is
one of the most common causes
of worker deaths among incidents
investigated by the agency. The CSB
continues to see hot work incidents
and has found a significant subset
of occurrences-those involving
piping, tanks, or containers where
flammables are present-to be particularly dangerous. In addition,
the CSB repeatedly observes hot
work incidents involving tanks or
containers at high-hazard facilities
such as refineries and chemical
plants that typically result in injuries and fatalities and have the
potential to result in major catastrophic accidents.
Since 2001, the CSB has
deployed to and investigated 14
hot work-related incidents that
have resulted in 25 fatalities and
21 injuries to employees and
members of the public. The CSB
continues to monitor hot work
incidents where continuous monitoring could have alerted workers
to the changing conditions in areas
where hot work activity was conducted. In an education session at
the upcoming NFPA Conference &
Expo, a CSB investigator will present a case study of an investigation
into a 2016 hot work-related flash
fire at an oil terminal in Texas.

The CSB began investigating hot
work hazards following a July
17, 2001, explosion at the Motiva
Enterprises refinery in Delaware
City, Delaware. A work crew was
repairing a catwalk above a sulfuric acid storage tank farm when a
spark from their hot work ignited
flammable vapors in one of the
tanks. Corrosion had caused holes
in the roof and shell of the tank,
allowing sulfuric acid to leak. The
