SAFE WORK PERMIT GUIDELINES
1.0
PURPOSE
This guideline defines minimum permit requirements, procedures, limitations and provides
forms for the issuance of safe work permits within the facility.
2.0
SCOPE
This guideline applies to all persons including Valero and contractor personnel and defines
permit requirements, procedures, limitations and forms used in the issuance of safe work
permits, including cold work, hot work, vehicle entry, excavation and confined space entry
permits to assure consistent safe work permitting within the facility. A safe work permit is
required for any Maintenance, repair or construction work within the facility. Permits are
generally not required for work performed in office buildings and Maintenance shops except for
confined space entry and hot work on equipment that has been in service. Cold work
performed by owning area personnel does not require a safe work permit.
3.0
DEFINITIONS

Acceptable Entry Conditions - The atmospheric, access/ egress, and work area
conditions that must exist in a confined space before entry is allowed.

Authorized Entrant - A person who is authorized under the terms of the confined space
entry permit to enter and exit the space.

Blanket Safe Work Permit - A cold work permit issued within a defined section (see
Section 5.1 - Permitting for Cold Work and Line Break) to allow work on a grouping of
closely interrelated or similar pieces of equipment (e.g., groups of exchangers, pumps,
vessels and connecting piping, etc.).

Cold Work - Any work activity which does not supply sufficient heat or spark energy to
provide a potential ignition source for a flammable mixture. This includes general work,
scaffolding, cleanup, etc. Hot work, vehicle entry, excavation or confined space entry
are not classified as cold work.

Competent Person - For the purposes of excavations, an authorized person who is
trained in and is capable of identifying existing and predictable hazards in the
surroundings, or working conditions which are unsanitary, hazardous or dangerous to
employees, and who has authorization to take prompt corrective action to eliminate
them.

Revised: 10/6/03
Confined Space - A space that is:
•
Sufficiently large and so configured that an individual can bodily enter and
perform assigned work;
•
Has limited or restricted means of entry or exit;
•
Is not designed for continuous occupancy; and
•
May contain one of the following:
·
Contains or has the potential to contain a hazardous atmosphere;
·
Contains a material that has the potential of engulfing an individual;
·
Has an internal configuration such that an entrant could be trapped or
asphyxiated by inwardly converging walls or by floors which slope
downward and taper to a smaller cross-section; or
·
Contains any other recognized serious safety and health hazard.
•
•
Examples of confined spaces include but are not limited to: (a) tanks, (b)
reactors, (c) vessels, (d) towers, (e) drums, (f) sumps, (g) external floating roofs
greater than 12 inches below the maximum fill level, (h) excavations greater than
4 feet deep, and (I) tower skirts.
In addition, temporary shelters used for welding, inspections, etc., where there is
a potential for build-up of toxic materials or oxygen depletion may be considered
a confined space. These must be evaluated on a case by case bases by the
owning department.

Designated Attendant – A qualified individual ("hole watch") stationed outside a
confined space as required by the confined space entry procedure.

Entry - The action by which an individual passes through an opening into a confined
space. Entry is considered to have occurred as soon as any part of the entrant's body
breaks the plane of an opening into the space.

Entry Supervisor - The individual (Superintendent, Shift Supervisor, Lead Technician)
responsible for confined space entry activities. This function cannot be delegated.

Fire Watch - A qualified person designated to monitor the area of hot work involving
welding or cutting, take appropriate action to reduce risk of fire and if necessary
extinguish an incipient stage fire.

Hazardous Atmosphere - An atmosphere that may expose entrants to the risk
of death, impairment of ability to exit, injury or acute illness from one or more of the
following causes:
•
Flammable gas, vapor or mist in excess of 10 percent of the lower explosive limit
(LEL)
•
Atmospheric oxygen concentrations below 19.5% or in excess of 23.5%
•
Atmospheric concentration of any substance which could result in employee
exposure in excess of its permissible exposure limits (PEL)
•
Any other atmospheric condition that is Immediately Dangerous to Life or Health
(IDLH)
VALERO – KROTZ SPRINGS
SHG #3
Page 5 of 40
Revised: 10/6/03

Hot Work- Work that causes or requires the use of open flames, arcs, sparks, or other
forms of high temperature ignition sources that could initiate a fire or explosion.
Examples of hot work include welding, burning, soldering, hot tapping/stoppling, drilling,
grinding, abrasive blasting, chipping, the operation of impact wrenches, the operation of
electronic or electrical equipment that is not intrinsically safe, opening explosion proof
electrical enclosures and any other work that may generate sufficient heat that it would
pose a possible ignition source.

Immediately Dangerous to Life and Health (IDLH) - Any condition that (a) poses an
immediate or delayed threat to life; or (b) would cause an irreversible adverse health
effect; or (c) would interfere with an individual's ability to escape unaided from a
confined space. The level of contaminant that would pose an IDLH atmosphere is
substance specific.

Inerting - The displacement of an atmosphere in a confined space by a noncombustible
gas such as nitrogen, to such an extent that the resulting atmosphere will not support
combustion or life.
NOTE - This condition results in an IDLH (oxygen deficient) atmosphere. Inert confined
space entries are not normally done by company personnel.

In-Service Welding - The practice of welding on equipment (e.g., tank, pipe, vessel,
exchanger, etc.) which has not been purged (gas free) and has not been removed from
service through conventional methods. This includes but is not limited to grinding,
burning or welding.

Joint Job Site Visit - A visit to the job area by an Operations person and the person to
do the work (or a representative of the person(s) to do the work) to ensure the safety of
the workers and the operation by identifying the hazards associated with the job and the
measures and equipment to be used to mitigate or eliminate the hazards. Safety
Department personnel may be included in the visit for higher risk or more unusual jobs.
The hazards listed and referred to in sections B – E of the permit form should be
considered, as well as all other potential hazards. When a job extends beyond the valid
date of the first permit, the extent of the Joint Job Site Visit evaluation may be reduced
(as compared to the first permit Joint Job Site Visit) if appropriate in the judgment of the
joint visitors.

Line Break - The intentional opening of a process system that may contain flammable,
corrosive, or toxic material, or a material under pressure or temperature such that an
unplanned opening of the system may result in injury to workers. Examples include
spreading flanges, opening exchangers, pulling pumps, cold cutting pipe, etc. Line
break, depending on equipment used, could be cold work or hot work.

Non-Hazardous Confined Space - A confined space which normally exists without
IDLH conditions. Entry into such spaces requires the issuance of a confined space
entry permit. No blinding is required by the Owning Department as part of the permit
issuance. Non-hazardous confined spaces are floating roof tank tops, tower skirts,
sunken valve and pump manifold areas, cooling tower cells, and fin fans.

Revised: 10/6/03

Owning Department - The unit/area/department that is responsible for the location in
which the work is performed.

Owning Department Representative - Individuals who have received training and a
certification of competency in the issuance of permits and associated gas testing.
Certification of competency requires passing a standardized written examination.

Retrieval System - The equipment used for non-entry rescue of persons from confined
spaces such as a safety harness and life line.

Testing - The process by which the hazards that may confront personnel performing hot
work, vehicle entry, or authorized entrants of a confined space are identified and
evaluated.

Vehicle Entry - The entry of any motorized vehicle into the battery limits of a process
unit, inside tank farm diked areas, or other restricted areas except for trucks loading or
unloading at racks.

Mounted Enclosure – small enough to prevent complete physical entry (e.g., cabinet,
junction box, analyzer enclosure, etc.).

Walk-in Enclosure – similar to mounted enclosure, but large enough to allow complete
physical entry (e.g., walk-in compressor control equipment).

Non-Pressurized Building Containing Enclosure(s) – building containing purged or
pressurized equipment (e.g., analyzer building, blend building, etc.)

Pressurized Building Containing Pneumatic Controls – pressurized building
containing control equipment that has the potential to release purged air (e.g.,
pressurized control room)

guideline.

Prior to beginning the excavation and as part of permit preparation, the
Maintenance Department will contact if appropriate local or state
authorities, companies or utilities. Contractors must contact the
Maintenance Department before any excavation work is done.
Upon receipt of a Maintenance work order or request, the Owning
Department will prepare an Excavation Permit based on:
∙ Understanding the nature and extent of the work to be done.
∙ A review of the impact of the work on the operability/ safety of the
process or general area by conducting a job site visit before the permit
is issued. Typically, this will require a visit made jointly with the
company work crew or contractor representative BEFORE THE WORK
IS ALLOWED TO BEGIN (see Appendix 1, Section B). Drawings of
underground tanks, lines and utilities will be reviewed as needed.
∙ Perform gas testing of the area as needed.
∙ Ensure that the results of any gas tests taken are included on the
permit, including the serial number and date of last calibration of the
instrument used.
∙ Communicate to the persons who will perform the work, the personal
protective equipment and other precautions that need to be taken to
perform the work safely.
∙ Ensure that the immediate and surrounding area to be involved is
appropriately prepared, i.e., sewers covered, perimeter barricaded,
equipment drained and cleaned, combustibles removed, a spoil area or
container established, etc.
∙ Ensure that all personnel who may be impacted by the work are aware
that the work is commencing.

Permitting for "Non-Hazardous" Confined Space Entry
Certain spaces meeting the OSHA definition of "confined space" exist within the refinery
by virtue of equipment of process design or layout. They are "confined spaces" either
due to their limited access or egress and are "not designed for continuous occupancy."
These spaces are identified by warning signs. Non-Hazardous confined spaces are:
∙
∙
∙
∙
∙
External Floating Roof Tank Tops (Refer to SHG #16 for special requirements)
Tower Skirts
Equipment Installed more than 4 Feet Below Grade Within Concrete Containment
Basins (e.g., Valve and Pump Manifold Areas and Some Tanks)
Cooling Tower Cells
Fin Fans (may not have warning signs)

Entry into such spaces requires the issuance of a confined space entry permit. However,
no blinding or area preparation is typically required by the Owning Department personnel as
part of the permit issuance.

HS&E personnel do not need to sign the Confined Space Permit for "non-hazardous"
confined space entry. All other signatures and requirements typical of the
preparation and issuance of these and the subsequent confined space entry permits
issued to each work group entering the confined space remain the same.

“C”, “D”, and “E”.
Check all boxes that apply.
A joint job site visit, i.e., a collective visit to the work site by an Owning Department
representative and a work crew representative, is REQUIRED for hot work, hot tap/stopple
work, confined space entries, excavations, opening lines or equipment, and work requiring
the use of supplied breathing air. The person issuing the permit must determine, by the
nature of the hazards involved, the requirement of a joint job site visit in regards to work not
listed. The purpose of the collective visit is to identify and discuss the work to be done,
procedures to be used, and precautions to be taken. Information generated by this
discussion, in conjunction with the green copy of the permit, is used to prepare the safe
work permit.
Check JSA Completed box if a Formal (written) Job Safety Analysis is done.
The Owning Department representative will review the area for potential or actual hazards
and bring the green copy of the permit into the field for reference as part of the permit
preparation. The Maintenance representative will visit the site of the work to ensure that the
area has been made ready for work activities.
Even for repetitive or continuing type work, the Owning Department representative should
revisit the area each time the permit is reissued or renewed to assure that conditions have
not changed and that adequate housekeeping is being maintained, even during construction
activities. Some examples of repetitive type work are general clean-up or housekeeping
tasks, general preparatory work (i.e., scaffold building, creation of lay down areas, and
multiple day new construction, such as tank/unit construction, etc).

F.
ATMOSPHERIC TESTING

This section is to be completed by the Operations Lead Process Tech and/or qualified
Owning Department representative.
The Operations Lead Process Tech or qualified Owning Department representative will
perform all necessary atmospheric testing for hot work. The results of the testing will be
recorded on the permit along with the time the test was taken and the serial number(s) and
type of the gas testing equipment used. The name of the individual performing the testing
will also be printed on the permit in the blank indicated "Tested By:".
Gas tests must be taken as part of a hot work permit issuance where the work will be done
in an area that is electrically classified as a Division 1 or 2 area, which includes the following
types of areas:


(1)
(2)
(3)


ISBL (Inside Battery Limits) within any process operating unit;
Within the confines of any tank farm dike or retaining wall;
Within active hydrocarbon tank truck, rail car, or barge/ship loading/unloading areas;
In the area of gaseous hydrogen storage;
Within 30 feet of active open process sewers and/or separators;
Within 25 feet of active hydrocarbon conveying pipelines; or
Within any excavation.
Neither hot work permits nor gas tests are normally needed for hot work within plant shops.
Permits and/or gas testing may be needed when process equipment, vessels, drums, and
containers are moved into shop areas for work.
VALERO – KROTZ SPRINGS




Hot work permits are needed, but gas tests are not normally needed, for hot work
performed within office buildings, labs or control rooms.
The Serial Number and Calibration Date of the gas testing device(s) used will be recorded
on the permit along with the brand or type of equipment.
During the preparation of the hot work permit, it should be determined whether periodic
follow up or continuous testing will be required due to the nature of the work. This decision
is based on whether the work activities themselves or conditions within the work area may
change the atmospheric quality during the work. Questions regarding uncertainties will be
referred to the Safety Department for resolution.
When the qualified Owning Department representative is performing the atmospheric
testing for HOT WORK, the following conditions must be met prior to issuing the permit:
Oxygen
Combustible Gas (LEL)

Additional information on vapors or gases that may be present within a confined space may
also be available on Material Safety Data Sheets for materials that have occupied the
confined space.
Determine if these initial conditions could change over time due to the type of work to be
done, a change in confined space conditions, etc.
If the atmosphere quality could change over time, then the atmosphere within the space will
either be periodically or continuously monitored to assure that personnel in the area are not
endangered.
When testing for atmospheric hazards, oxygen will be tested first, then combustible gases
and vapors, and then toxic gases and vapors. (NOTE - The MSA Passport and similar
instruments test all of these parameters simultaneously.)
At a minimum, retesting of the atmosphere is required at the beginning of each
Maintenance work shift. If work does not begin within two hours of a gas test, the area or
space must again be retested.
When checking for combustible gases, the reading may not be accurate if there is
insufficient oxygen. There must be at least 10% oxygen in the atmosphere for the LEL
reading to be correct.
Gas testing in the presence of excessive steam will cause the gas-testing instrument to
provide inaccurate readings and may damage the meter.
If temperatures are in excess of 150o F, readings will not be accurate.
Check the meter to ensure that it responds properly prior to each use. If the meter does not
respond properly, tag it and return it to the designated location within the refinery for
recalibration and/or repairs.
Combustible liquids may be present which do not vaporize and register on the meter.
These hazards must be visually identified.

If the work was performed as a result of a MOCA and a PSSR is required, the Owning
Department Representative shall ensure the necessary tag(s) is placed and note this on the
permit.
If the permit was a Confined Space Entry Permit, the Owning Department representative
should promptly sign the bottom line of the permit indicating that the permit is canceled.

APPENDIX 2 - CONFINED SPACE PERMIT
(Permits Issued to the Space or Vessel)
GENERAL INSTRUCTIONS ON COMPLETING PERMIT
Note: The following sections refer to the corresponding letter on the permit form.
A.
WORK SCOPE

When filling out the Permit, identify the specific location of the confined space (i.e., refinery
area, the specific equipment to be worked on, and describe the work to be done. A
complete understanding of this information is important to the permit writer since it will often
influence the type of gas testing to be done as well as the decision regarding whether
periodic retest or continuous monitoring of the confined space atmosphere is needed.
Unless special provisions are made, a new permit is required at the beginning of each new
work shift for the Owning Department. This should be reflected in the VALID UNTIL time
frame box provided.

B.
CHECKLIST

The considerations necessary for proper preparation of a confined space for entry are listed
under three headings: vessel draining/purging, vessel isolation, and potential hazards.
Each item under these heading should be considered as to whether this action is necessary
for preparation of the space. A check mark or "x" should appear in one of the three boxes
next to each consideration.
If a consideration does not apply to a particular confined space, the box marked "N/A" (Not
Applicable) should be marked.
If a confined space permit is being written for an excavated hole, most, if not all of the items
under Vessel Draining/Purging and Vessel Isolation will be marked as N/A except for
Access/Egress To/From Space Okay.
IT IS IMPERATIVE THAT FREE ACCESS TO and EGRESS FROM CONFINED SPACES
BE MAINTAINED AT ALL TIMES WHEN ENTRY IS UNDERWAY.
Any potential hazards that may still be present in the space after preparation should be
identified as a reference when preparing the confined space entry permit for a particular
craft or Maintenance group.
BEFORE opening a vessel, owning area and Maintenance personnel should also consider
whether pyrophoric iron sulfide or other deposits may be present. If pyrophoric materials
may be present, personnel should follow the refinery pyrophoric hazard safety instructions
as part of preparing the vessel for entry.
The Entry Supervisor and Qualified Owning Area Representative must field evaluate for the
initial confined space entry and review the Confined Space Permit. The entry supervisor
may delegate to a qualified representative, the field evaluation for non-hazardous confined
spaces and renewed confined space entries. The field evaluation and permit review help
assure that all appropriate precautions and restrictions are considered such as:
All lines entering the confined space are disconnected or blinded (any exception to this must
be approved by the affected Department Manager).
The vessel must be cleaned as thoroughly as possible by draining, water washing,
steaming, forced ventilation or other suitable means before any employee enters the
confined space for additional cleaning or other work.
Irritating fumes, dust and mist, if present or may be generated, will warrant either additional
cleaning, local exhaust ventilation or personal protective equipment.

PRECAUTIONS

When opening confined spaces for entry, danger signs will be posted at the entry portal
indicating " Enter by Permit Only" (or equivalent wording). These signs must be posted as
soon as the confined space is opened and will be removed when closed.
When entrance covers/manways are removed, the opening will be promptly guarded by a
railing, temporary cover, or temporary barrier that will prevent an accidental fall through the
opening and that will protect employees in the confined space from foreign objects entering
the space.
Equipment that is always open to the atmosphere such as tower skirts, tanks with open top
floating roofs, etc., and is identified as a confined space will be identified with the wording
"Enter by Permit Only."
During confined space entry, communications between designated attendants and
authorized entrants must be maintained throughout the entry. Methods of communication
that may be used include visual, air horns, voice, radio, rapping or tapping codes, signaling
tugs on a rope, etc., all of which may be used by the attendant to ascertain that work
activities are continuing normally.
In the event the designated attendant recognizes the need to evacuate the confined space,
an air horn (or any agreed to signal) will be sounded to notify the authorized entrants.
At least one trained designated attendant will remain outside the confined space and be in
constant communication with the authorized entrant inside the confined space and have a
means to summon rescue personnel and/or the Entry Supervisor. If the designated
attendant must leave for any reason, he/she must be properly relieved or the entrant(s)
must exit the confined space. The individual relieving the designated attendant must record
their name on the field copy of the Confined Space Permit.
Forced ventilation (e.g., air horn, air mover, or blower) is recommended for all (except inert
or IDLH) confined space entry, and when used, MUST BE GROUNDED.
Plant air valves used for ventilation equipment must be identified and the attendant must be
aware of its location.
Any mixer or other such device inside a confined space must be mechanically or electrically
disconnected. (See Lock, Tag, & Try, SHG #11)
Any radiation sources affixed to the space must have their shutters closed and locked.
Tanks/vessels that have been in leaded gasoline service must be considered a lead hazard
and all precautions taken until cleaned and a lead in air analysis completed.
As part of the initial entry permit for desalters, crude oil and cat feed tanks, a radiation
exposure measurement should be taken to assure significant levels of NORM (Naturally
Occurring Radioactive Material) are not present. These measurements can be arranged by
contacting the Environmental or Safety staff.
Artificial lighting should consist of equipment suitable for use in a confined space, (e.g.,
sealed flashlights, low voltage lighting with bulb protectors, ground fault circuit interrupters,
etc.).
Prior to IDLH entry, a Safety Department representative or Rescue Team member must be
notified.

ATMOSPHERIC TESTING


Gas testing devices will be bump-tested prior to each shift and results logged.
The Owning Area Supervisor or qualified Owning Department representative will perform all
necessary atmospheric testing for confined space entry work. The results of the testing will
be recorded on the permit along with the time the test was taken and the serial number(s)
and type of the gas testing equipment used. The individual performing the testing will also
sign the permit in the blank indicated "Tested By:"
The Serial Number and Calibration Date of the gas testing device(s) used will be recorded
on the permit along with the brand or model number of the device(s).
Initial testing performed in preparation of the Confined Space Permit must be reviewed with
a representative of the Safety Department who will also sign the permit.

Entry into a confined space may be allowed at concentrations higher than the above if
additional precautions such as respiratory protection is used. Questions concerning
appropriate respirators for confined space entry should be referred to Safety.
Additional information on vapors or gases that may be present within a confined space may
also be available on Material Safety Data Sheets for materials that have occupied the
confined space.
In NO case will a confined space be permitted for entry with >10% LEL.
The Owning Area Superintendent, Lead Process Tech or trained equivalent as the Entry
Supervisor must evaluate all confined space conditions as follows:
Test the conditions in the permit space to determine if acceptable entry conditions exist
before entry is authorized.
Determine if these initial conditions could change over time due to the type of work to be
done, a change in confined space conditions, etc.
When testing for atmospheric hazards, oxygen will be tested first, then combustible gases
and vapors, and then toxic gases and vapors. (NOTE - The MSA Passport and similar
instruments test all of these parameters simultaneously.)
When checking for combustible gases, the reading may not be accurate if there is
insufficient oxygen. There must be at least 10% oxygen in the atmosphere for the LEL
reading to be approximately correct.
Gas testing in the presence of excessive steam will cause the gas-testing instrument to
provide inaccurate readings and may damage the meter.
If temperatures are in excess of 150o F, readings will not be accurate. Snapshot readings
taken in ambient temperatures colder than 50o F. may not be accurate.
The meter should be checked with calibration gas to ensure that it responds properly prior
to each shift's use. If the meter does not respond properly, it should be tagged and
returned to the designated location within the refinery for recalibration and/or repairs.
Combustible liquids may be present which do not vaporize and register on the meter.
These hazards must be visually identified.

personal protective equipment specified to help assure that it is appropriate for the tasks
indicated and the expected conditions within the space.
All confined space permits must be canceled. If the signature line is not signed by the
qualified Owning Department representative or the Unit/Area Supervisor, then the permit is
canceled as of the time indicated in the VALID UNTIL blank at the top of the page.
Once the permit has been completed or canceled, it should be returned to the refinery
Safety Department for retention and subsequent review.
