POLICY
It is the Policy of Western Oregon University to be in compliance with
Oregon Administrative Rule (OAR) 437-2/j-1910.146. All persons who
enter a confined space as identified by this policy, will be required to
follow safety and engineering controls to prevent accidental or hazard
exposure that may cause injury or death. It is also the policy of Western
Oregon University that NO EMPLOYEE OR CONTRACTUAL EMPLOYEE WILL ENTER OR WORK
IN ANY CONFINED SPACE WHERE A HAZARDOUS ATMOSPHERE, ENTRAPMENT, ENGULFMENT OR
OTHER SERIOUS SAFETY OR HEALTH HAZARD IS POSSIBLE.
PURPOSE
The purpose of this policy is intended to identify and evaluate potential
hazards of work in confined spaces, assure use of protective measures in
these spaces to prevent injuries and fatalities by developing and
implementing procedures, and defining methods to prevent injuries and/or
illness.
DEFINITIONS
1. Confined Space - There are two levels of confined space:
? Level One - Spaces having limited access or egress which
can be bodily entered, however, are not designed for occupancy.
? Level Two - A "permit required" confined space where a
hazardous atmosphere, engulfment or entrapment is
possible, including but not limited to:
a. The potential to contain a hazardous atmosphere such as
oxygen deficiency, toxic or flammable vapors;
b. Engulfing, entrapping or asphyxiating a person or material;
c. Potential to cause serious injury or death (heat stress, moving
equipment, electricity);
d. Has an internal configuration such that an entrant could be
trapped or asphyxiated by inwardly converging walls or by a
floor which slopes downward and tapers to a smaller cross-
section;
e. Contains any other recognized serious health or safety hazard;
f. All "permit required" confined spaces will be identified by a
painted stencil mark or label stating, "Confined Space - Permit
Required".
2. Permit - A document that is to be posted at the entrance of a confined
space prior to entry which includes the following:
? General Information;
? Permit Space Hazards;
? Entry Preparation;
? Emergency Service;
? Equipment Required for Entry and Work;
? Communication Procedures;
? Authorized Attendants;
? Testing Record;
? Authorization by Entry Supervisors;
3. Attendant - A trained person who monitors the entrance, hazards,
personnel, emergency service, communications and equipment at a
confined space.
4. Entrant - A trained person who passes through an opening into a
permit-required confined space to ensure work activities. The
entrant is considered to have entered as soon as any part of the
entrant's face breaks the plane of an opening into a space.
5. Hazardous Atmosphere - An atmosphere which exposes persons to a
risk of injury, acute illness, impairment of ability to escape
unaided from a permitted space, incapacitation or death, from one
or more of the following common causes:
? Flammable - Gas, vapor or mist in excess of 10% of its
lower flammable limit (LFL);
? Airborne Dusts - Airborne combustible dust at a
concentration that meets or exceeds the LFL (this
concentration may be approximated as a condition in which
the dust obscures vision at a distance of 5 feet);
? Oxygen Levels - Atmospheric oxygen concentration below
19.5% or above 23.5%;
? Atmospheric Conditions - Any atmospheric condition that
is immediately dangerous to life or health (MSDS can
provide assistance).
6. Physical Hazards - Physical hazards in confined space may include
moving parts, valves and pipes, noise, heat, live wires, engulfment
and falling.
7. "Permit Required" Identified Confined Spaces - The following
locations are identified as permit entry confined spaces at Western:
? Sawdust bin collector located on the north side of the Physical Plant;
? Inner fining chamber of all four boilers in the Physical Plant;
? Condensate return tank located in the Physical Plant Boiler Room;
? Steam vent vault located on the east side of the University Center;
? Irrigation vault located to the southeast corner of Valsetz Dining Hall;
? Three irrigation control vaults on the east side of the football
field when any type of activity is being conducted other than mechanical
adjustments to the control systems;
? All electrical vaults located in parking lots or city streets
within the campus geographic perimeter;
? All storm vaults located in parking lots or city streets within
the campus geographic perimeter;
? Any confined space as described in the permit entry confined space
definition that has not been identified in this section.
PROCEDURES
1. Permit - "Permit required" spaces will not be entered until all
hazards are eliminated. A permit (attached) is required to be
completed for all "Permit Required Confined Space Entry Work."
Issued permits are to include all work to be done in the space
during a shift and encompass all participants, including the
following:
? General Information;
? Permit Space Hazards;
? Entry Preparation;
? Emergency Service;
? Equipment required for entry and work;
? Communication procedures;
? Authorized person that may enter the confined space;
? Authorized attendants;
? Testing record;
? Authorization by entry supervisors.
2. Monitoring - Is to occur in all portions, top to bottom, corners,
spaces, pipes and duct work of the space before and during entry.
Results are to be recorded on the permit for each entry.
? Elements Monitored - The confined space is to be monitored at all
times for oxygen, lower explosive limit (LEL), and carbon monoxide.
? Monitor Calibration - The monitor is to be calibrated prior to each
day's use to the manufacturers standard of operation for carbon
monoxide, hydrogen sulfide and oxygen.
? Alarms - Monitor alarms are to be set at 20.4% (lower limit)
and 21.4% (high limit) for oxygen, 10% of LEL for methane,
13 PPM (one-half of the ACGIH time-weighted average
exposure limit) for carbon monoxide.
? Maintenance on the monitor is to occur based on manufacturer's
recommendation.
3. Training - The Physical Plant Facilities Maintenance Supervisor
will provide confined space training to all employees assigned to
work as entry or standby personnel. Annual training by the
Physical Plant Facilities Supervisor will consist of the following:
? Hazard Communication;
? Confined Space Entry Equipment - Including lifeline, monitoring
instruments and methods, hoisting equipment, non-sparking tools,
ventilation equipment and communication methods;
? Emergency Rescue - Polk County Fire District Number One is designated
as the rescue agency for confined space rescue. Polk One is to be
notified prior to any confined space entry;
? Protective Equipment - Consists of eye, skin, and respiratory equipment
and their maintenance;
? Confined Space Entry - Review of entry to include ventilation,
isolation, communication, posting, barricading procedures and
protection from external hazards;
? Permits - Procedural and permit elements;
? Hazardous Atmosphere - Instructions including development, prevention,
control and working in hazardous atmospheres;
? Hazard Recognition - Identification of the types of hazards which can be
encountered, signs/symptoms of exposure, first aid procedures;
? Fall protection;
? Lock Out/Tag Out - Energy control procedures.
4. Confined Space Work Procedures
? Confined Space Entry Permit - The Physical Plant Facilities Supervisor
or his designee is the person responsible to authorize entries and have
oversight of the monitoring section of the permit.
? Unauthorized Entry - Work will not be performed in unauthorized confined
spaces by Western employees or contractors.
? Hazardous Free Spaces - Spaces are to be cleaned and purged prior to
entry to include being free of hazardous atmospheres. Oxygen content
of 20.4-21.4%, toxic content less than 1/2 of the exposure limits and
flammability levels at less than 10% of LEL for specific gas/vapor for
the entire entry period.
? Lock Out/Tag Out - Energy control procedures for all energy sources are
to be followed.
? Monitored Spaces - Spaces are to be monitored before entry and
continuously through the work process. Entry persons are to be
evacuated whenever a monitor alarm sounds, and reassessment of the
space performed.
? Ventilation will occur throughout the work if initial monitor results
indicate the atmosphere is not acceptable.
? Non-Sparking Tools - Only non-sparking tools may be used whenever
flammable or combustible atmospheres are capable of being created.
? Work Review is to occur prior to entry to determine of the work itself
will contribute to an unacceptable atmosphere, including welding and
gluing.
? Hot Work Permit - If equipment that generates a hazardous atmosphere by
consuming oxygen or creating a harmful vapor or gas is used in a
confined space, additional precautions are to take place to eliminate
the hazard and protect the entrant person. A second permit is required
detailing additional precautions required.
? Standby Person will be at the point of entry in constant communication
with the entry person(s). The standby person can order an evacuation
when a hazard or ill effect of an entrant is noted. The standby person
must summon Polk One for rescue.
? Rescue - Polk One will respond and rescue the entrant. If the person
has a lifeline the standby person is to call Public Safety for initial
response until Polk One arrives. If the person can be retrieved
through a pre-existing lifeline the standby person and Public Safety
may attempt to retrieve the person if it can be determined that no
urther serious harm will occur.
? Heat Stress and Disorders - Heat stress may cause a person to process
information poorly, disregard danger warnings, make poor choices, have
slower reaction time, have impaired coordination, or misjudge istances.
Persons who begin to experience heat cramps, heat exhaustion or heat
stroke are to remove themselves from the space.
5. Permit Entry Procedures - Persons who determine a need to enter a "permit
required" confined space are to comply with the following procedures:
? Inform supervisor.
? Determine Hazards - Determine the potential hazards in the confined
space (e.g., oxygen deficiency, internal configurations, or depths
impairing the ability to escape unaided should an injury or acute
illness occur).
? Test Atmosphere - Test upper and lower levels using the gas monitor
which may include using plastic tubing on the lower levels.
Ventilation is to occur if a hazard is identified or possible.
? Personal Protective Equipment - Wear protective equipment based on
potential hazardous atmosphere which may include, but not be limited
to, gloves, respirator, boots, etc. (This will include a lifeline,
shoulder harness, and retrieval system.)
? Complete Permit - Complete the entire permit and have it signed by the
Physical Plant Facilities Maintenance Supervisor.
? Standby Person - Is to be located at the entry point in constant
communication.
? Rescue Notification - Polk One is to be notified prior to entering a
confined space.
6. Contractors - When contracted work is to occur in a "permit required"
confined space the Physical Plant Facilities Supervisor is to be notified.
He will provide the contractor with Western's Confined Space Program, MSDS
and hazard information. It will be the responsibility of the contractor to
evaluate, monitor, and enter the space at their own assumption of risk.
7. Shared Work - In the event a contractor and Western work together in a
confined space, Western's confined space procedures will be followed.
AUTHORITY
Oregon Administrative Rule (OAR) 437-2/J-1910,146.
APPROVAL
Before entering a confined space, authorization must be received from the
