Acceptable entry conditions: the conditions that must exist in a confined space to allow entry and to ensure that employees involved with a confined space entry can safely enter into and work within the space.
Attendant: an individual stationed outside one or more Confined spaces who monitors the authorized entrants and who performs all Attendant's duties assigned in the VLakewoodEnergy Confined Spaces Program. Attendants must have sufficiently completed and fully understands the Confined Space training and are approved by the HSE Manager to work in a confined space as an Attendant.
Authorized Entrant: an individual who is authorized by the Company to enter a confined space. Entrants must have sufficiently completed and fully understands the Confined Space training and are approved by the HSE Manager to work in a confined space as an Authorized Entrant.
Blanking or Blinding: the absolute closure of a pipe, line, or duct by the fastening of a solid plate (such as a spectacle blind or a skillet blind) that completely covers the bore and that is capable of withstanding the maximum pressure of the pipe, line, or duct with no leakage beyond the plate.
Confined Space: A space that is large enough and so configured that an employee can bodily enter and perform assigned work; Has limited or restricted means for entry or exit (for example, tanks, vessels, coolers, storage bins, hoppers, vaults, and pits are spaces that may have limited means of entry); and Is not designed for continuous occupancy.
Double block and bleed: the closure of a line, duct, or pipe by closing and locking or tagging two in-line valves and by opening and locking or tagging a drain or vent valve in the line between the two closed valves.
Emergency: any occurrence (including any failure of hazard control or monitoring equipment) or an event internal or external to the confined space that could endanger Entrants.
Engulfment: the surrounding and effective capture of a person by a liquid or finely divided (flowable) solid substance that can be aspirated to cause death by filling or plugging the respiratory system or that can exert enough force on the body to cause death by strangulation, constriction, or crushing.
Entry: the action by which a person passes through an opening into a confined space. Entry includes ensuing work activities in that space and is considered to have occurred as soon as any part of the Entrant's body breaks the plane of an opening into a confined space.
Entry permit: means the written or printed document that is provided by the Company to allow and control entry into a confined space that contains the information specified in this program.
Entry Supervisor: the person responsible for determining if acceptable entry conditions are present at a confined space where entry is planned, for authorizing entry and overseeing entry operations, and for terminating entry as required by this section; Entry Supervisors must have sufficiently completed and fully understands the Confined Space training and is approved by the HSE Manager to work in a confined space; An Entry Supervisor also may serve as an Attendant or as an authorized entrant, as long as that person is trained and equipped as required by this section for each role he or she fills. Also, the duties of Entry Supervisor may be passed from one individual to another during the course of an entry operation; The Entry Supervisor is responsible to test and monitor the atmospheric conditions.
Hazardous atmosphere: an atmosphere that may expose employees to the risk of death, incapacitation, and impairment of ability to self-rescue (that is, escape unaided from a confined space), injury, or acute illness from one or more of the following causes: Flammable gas, vapor, or mist in excess of 10 percent of its lower flammable limit (LFL), (0% is normal); Atmospheric oxygen concentration below 19.5 percent or above 23.5 percent, (20.9 % is normal); Any other atmospheric condition that is immediately dangerous to life or health. (Ex.-H2S 10%, 0% is normal). Note: For air contaminants for which OSHA has not determined a dose or permissible exposure limit, other sources of information, such as Safety Data Sheets that comply with the Hazard Communication Standard, published information, and internal documents can provide guidance in establishing acceptable atmospheric conditions.
Hot work permit: the written authorization to perform operations (for example, riveting, welding, cutting, burning, and heating) capable of providing a source of ignition.
Immediately dangerous to life or health (IDLH): any condition that poses an immediate or delayed threat to life or that would cause irreversible adverse health effects or that would interfere with an individual's ability to escape unaided from a confined space. Note: Some materials -- hydrogen fluoride gas and cadmium vapor, for example -- may produce immediate transient effects that, even if severe, may pass without medical attention, but are followed by sudden, possibly fatal collapse 12-72 hours after exposure. The victim "feels normal" from recovery from transient effects until collapse. Such materials in hazardous quantities are considered to be “immediately dangerous to life or health”.
Inerting: the displacement of the atmosphere in a permit space by a non-combustible gas (such as nitrogen) to such an extent that the resulting atmosphere is non-combustible. This procedure produces an IDLH oxygen-deficient atmosphere.
Isolation: the process by which a confined space is removed from service and completely protected against the release of energy and material into the space by such means as blanking or blinding, misaligning or removing sections of lines, pipes, or ducts; a double block and bleed system, lockout or tagout of all sources of energy, or blocking or disconnecting all mechanical linkages.
Line Breaking: the intentional opening of a pipe, line, or duct that is or has been carrying flammable, corrosive, or toxic material, an inert gas, or any fluid at a volume, pressure, or temperature capable of causing injury.
Non-Permit Confined Space: A confined space that does not contain or, with respect to atmospheric hazards, have the potential to contain any hazard capable of causing death or serious physical harm.
Oxygen deficient atmosphere: an atmosphere containing less than 19.5 percent oxygen by volume.
Oxygen enriched atmosphere: an atmosphere containing more than 23.5 percent oxygen by volume.
Permit-Required Confined Space: a confined space that has one or more of the following characteristics: Contains or has a potential to contain a hazardous atmosphere; Contains a material that has the potential for engulfing an entrant; 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; Contains any other recognized serious safety or health hazard.
Permit system: the employer's written procedure for preparing and issuing permits for entry and for returning the confined space to service following termination of entry.
Prohibited condition: any condition in a confined space that is not allowed by the permit during the period when the entry is authorized.
Rescue service: the personnel designated to rescue employees from Permit-Required Confined Spaces.
Retrieval system: the equipment (including a retrieval line, chest or full-body harness, wristlets, if appropriate, and a lifting device or anchor) used for non-entry rescue of persons from confined spaces.
Testing: the process by which the hazards that may confront Entrants of a confined space are identified and evaluated. Testing includes specifying the tests that are to be performed in the permit space.
