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 toxic gases and vapors while performing work in the
Isomax, Alkylation, and
Unifiner control rooms.
The employer did not provide a ventilation system that met the
requirements of National Fire
Protection Association Standard for Purged and Pressurized Enclosures,
NPFA
496.
Among other methods, a feasible and acceptable abatement to correct this
problem is:
1)Provide a backup ventilation system with a manifolded compressed air
system that will
maintain positive pressure during a hazardous gas or vapor release.
2)Provide detectors with alarms and/or interlocks in the control room
ventilation system
to monitor for entry of flammable and hazardous substances such as
hydrogen sulfide,
hydrofluoric acid, and flammable hydrocarbon.
3)Provide ventilation ducting away from the building to a location where
the presence of
flammable/hazardous gases will be minimal.
4)Provide SCBA's in sufficient quantity to allow personnel to work in
unknown
concentration of flammable or toxic gases.
5)Provide positive pressure indicator to verify the control room's degree
of pressurization.
6)Provide the Isomax control room with a readable panel indicator if
positive pressure is
lost.
7)Provide the HF-Alky operators with portable detectors for hydrofluoric
acid.

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 being struck by falling debris and hit  by flying objects
due to controls rooms
that were not capable of resisting an unconfined vapor cloud explosion or
located within the
critical radius of such an explosion:
a)Isomax control room.
b)HF-Alky control room.
c)Unifiner control room.
Among others, one feasible method of abatement to correct this hazard
includes, but is not
limited to:
1)Following guidelines for plant layout and spacing.  Such guidelines may
include:
a.The Dow Chemical Company "Fire and Explosion Index Hazard Classification
Guide."
b.Factory Mutual Loss Prevention Data Sheet, "Spacing of Facilities in
Outdoor
Chemical Plants."
2)If adequate spacing cannot be achieved, alternative methods of
protection must be
implemented such as explosion resistant construction or adequate
barricading.

%%
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 unknown concentrations of toxic
hydrofluoric acid vapors upon release from pressure vessels and piping in

Among feasible methods of abatement would be to install fixed HF detectors
in the
unit similiar to that of the Claus Unit for hydrogen sulfide.

Feasible abatement would be to label valves identified in emergency
shutdown
procedures with
tags or other identifiers and to include the valve identification on
future piping and

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:
hydrocarbon fire and or explosion hazards from the rupture or failure of
pressure
vessels, exchangers, and/or piping due to inadvertent closure of a block
valve(s)
upstream and/downstream of a safety relief valve.
Safety relief valves with block valves located as described above include,
but not
limited to the following:
(a) The pilot relief valve located at the Isomax vessel 12v3, Stage I
Separator.
(b) The pilot relief valve located at the Isomax vessel 12v7, Stage II
Separator.
Among others, a feasible and useful method to correct these hazards is set
forth
below:
Install "car seals" or use locks and chains to prevent valves from being
inadvertently operated as specified in API Recommended Practice 520 or
Section VIII,
Appendix M, of the ASME Code.

recognized hazards that
were causing or likely to cause death or serious physical harm to
employees in that employees

Association, NFPA
85A, Standard for Prevention of Furnace Explosions in Fuel Oil- and
Natural Gas-Fired Single
Burner Boiler-Furnaces.
1)Provide a convenient observation port on the control side that will
allow the fireman to
visual inspect the main burner flame or other applicable procedures, such
as, utilizing
2 employees during boiler start-up.
2)Provide a reliable control to shut off main flame fuel if ignition has
not occurred within
10 seconds.
3)Provide a control that will verify that the supervisor gas cock is
closed before starting
the purge system.
4)Provide a control that will initiate a safety shutdown upon detection of
low gas pressure.
