General-duty citation text

Section 5(a)(1) of the Occupational Safety and Health Act of 1970:  The
employer did not furnish employment
and a place of employment which were free from recognized hazards that
were causing or likely to cause
death or serious physical harm to employees in that employees were exposed
to wood dust explosion,
deflagration, or other fire hazards:
a.On or before June 4, 2009, in the mill, surfaces were not cleaned in a
manner that minimized the
generation of wood dust clouds due to the employer permitting the use of
compressed air (tested at 75
psi) for the removal of wood dust and not taking the necessary precautions
such as vacuuming prior to
blowdown and using non-sparking shovels and hoes.
ABATEMENT NOTE:  Among other methods, one feasible and acceptable
abatement method to
correct this hazard includes following NFPA 664, Standard for the
Prevention of Fires and Explosions
in Wood Processing and Woodworking Facilities (2007 Edition), including,
but not limited to:
discontinuing the use of compressed air or reducing the compressed air to
15
psi and taking additional
precautions such as vacuuming prior to blowdown, shutting down electrical
power and other sources of
ignition, removing open flames, spark-producing equipment or hot surfaces,
and ensuring that all fire
equipment is in service.
b.On or about May 28, 2009, large sections of ductwork used to
pneumatically convey wood dust from
the various wood processing machines in the dimensions shop to the dry
dust building were not
metallic and were nonconductive in construction such as the use of PVC
pipes.
ABATEMENT NOTE:  Among other methods, one feasible and acceptable
abatement method to
correct this hazard includes following NFPA 664, Standard for the
Prevention of Fires and Explosions
in Wood Processing and Woodworking Facilities (2007 Edition), including,
but not limited to:
removing all plastic/PVC pipes and using only metallic ductwork which is
conductive.
c.On or about May 28, 2009, in the mill, foreign metallic material was not
removed from the process
material feed into the Morbark chipper.
ABATEMENT NOTE:  Among other methods, one feasible and acceptable
abatement method to
correct this hazard includes following NFPA 664, Standard for the
Prevention of Fires and Explosions
in Wood Processing and Woodworking Facilities (2007 Edition), including,
but not limited to:
installing a metal detector interlocked to shut down the flow of material
or a magnetic separator
upstream of the chipper.
d.On or about May 28, 2009, in the mill, an enclosed dust
collector/baghouse located inside for the trim
saw was constructed partially of combustible material, was not equipped
with a deflagration
suppression system or deflagration relief vents, and for the recycled
exhaust air inside the building was
not equipped with a spark detection system connected directly to a spark
extinguishing system or
equivalent.
ABATEMENT NOTE:  Among other methods, one feasible and acceptable
abatement method to
correct this hazard includes following NFPA 664, Standard for the
Prevention of Fires and Explosions
in Wood Processing and Woodworking Facilities (2007 Edition), including,
but not limited to:
removing the dust collector from inside the mill, redesigning and
constructing the dust collector of
welded steel or other noncombustible material of sufficient strength to
withstand the maximum
unvented deflagration pressure of the material being collected, or
equipping the dust collector with a
listed deflagration suppression system or deflagration relief vents with
the proper venting; and for the
recycled exhaust air, exhausting air outside of the building or equipping
the dust collector with a spark
detection system connected directly to a spark extinguishing system or
high-speed abort gate.
e.On or about May 28, 2009, in the dry dust building where wood dust was
pneumatically conveyed
from the dimensions shop, the structure was not designed, constructed, and
maintained
to prevent
deflagrations from causing failure of load-bearing structural members and
propagating into adjacentwork areas, the two cyclones located inside the
building had no explosion protection system, and the
ducts entering the dry dust building from the material entry points were
not equipped with a spark
detection and extinguishing system or equivalent.
ABATEMENT NOTE:  Among other methods, one feasible and acceptable
abatement method to
correct this hazard includes following NFPA 664, Standard for the
Prevention of Fires and Explosions
in Wood Processing and Woodworking Facilities (2007 Edition), including,
but not limited to:
designing the fire and deflagration safety provisions of the dry dust
building collection process based
upon an analysis of the process and the fire and deflagration hazards
encompassed by the process;
locating, designing, constructing, equipping, and maintaining the
structure to prevent deflagrations
from causing failure of structural members and propagating into adjacent
areas; and designing
pneumatic conveying systems in accordance with NFPA 654, Standard for the
Prevention
of Fire and
Dust Explosions from the Manufacturing, Processing, and Handling of
Combustible Particulate Solids.late
