Procedure No.: WYN032.018 Page: 5 of 25 3. SCOPE This procedure applies to BASF Wyandotte Facility located in Wyandotte, MI. On the Wyandotte site all identified confined spaces are to be treated and classified as Permitrequired Confined Spaces, as referenced in the Federal and state plan standards (29 CFR 1910.146 and MIOSHA Part 90 and 490); regardless of the fact that the space may not meet the regulatory definition of a PRCS. In addition, the BASF Wyandotte site does not allow for Alternate Entry Procedures (c) (5) spaces and permit space reclassification (c) (7) which are not recognized by BASF Corporate policy. However under special circumstances and with approval from the Wyandotte EHS group and the owning group the Wyandotte site will consider alternate entry procedure outlined in MIOSHA Part 90/490. This Wyandotte Site Confined Space Entry procedure does not apply to: Construction related work activities regulated by 29 CFR 1926 subpart P Excavations or MIOSHA Construction Safety Part 9 Excavation, Trenching & Shoring. All elevator work at the Wyandotte site will require a confined space permit if the space meets the definition of a confined space and has one or more of the characteristics of a hazardous atmosphere as described under 2.12 of this procedure. 4. PROCEDURE 4.1. General Requirements/Information Each Operating/Owning Department at the Wyandotte site shall evaluate the workplace to determine if any spaces meet the definition of confined space as defined in Section 2 and Section 4.1.1. This assessment is not required to be documented. 4.1.1. Evaluation Each Confined Space must be evaluated to determine the potential for hazards according to the intended service or use, not after a given hazard(s) has been eliminated or controlled. If any of the following apply, these Confined Spaces may only be entered by the issuance of a Confined Space Entry Permit. Does the confined space contain or have the potential to contain a Hazardous Atmosphere (such as, previously contained flammable, combustible, acidic, caustic, or toxic materials) or where oxygen enriched or deficient atmospheres or noxious odors may exist. Does the confined space contain a material that has the potential for engulfing an entrant? Does the confined space have 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 crosssection? Does the confined space contain any other recognized serious safety or health hazards; such as ionizing radiation, electric shock, temperature, or moving parts
Procedure No.: WYN032.018 Page: 6 of 25 Each group on the Wyandotte site is encouraged to have a written confined space evaluation as part of their unit addendum to the Wyandotte site program that includes how and which spaces have been identified as confined spaces. Refer to WYN032.018B for an example of an evaluation tool. In addition each unit/group is required to maintain a list of confined spaces specific for their area. Any changes will require a review by the EHS group. 4.1.2. Confined Space Identification Each Operating/Owning Department shall inform exposed personnel, by posting danger signs or by other equally effective means, of the existence and location of the danger posed by the location s Permitted-required Confined Spaces. Other acceptable means of informing exposed employees of the existence and location of the dangers posed by the permit spaces, include but are not limited to; computer based training (CBT), unit safety meetings, or similar communication means. 4.1.3. Authorization Only properly trained and authorized personnel may enter confined spaces. Confined spaces will only be entered using an approved confined space permit which follows the following procedure: If the initial evaluation of the space was yes to any question in Section 4.1.1 of the evaluation, then a Confined Space Entry Permit is required. If the initial evaluation was no to ALL of the questions in the Section, 4.1.1 of the evaluation, then entry may be authorized through a Safe Work Permit process, provided that initial air monitoring of the space is conducted using properly calibrated and maintained direct-reading instruments or equipment. If it is necessary to enter the space to eliminate or determine a hazard via monitoring or inspection, a confined space entry permit and requirements of this procedure are required. 4.1.4. Permit System Each facility shall establish a written site program for confined space entry that includes: Identification, communication and training of Confined Spaces, Issuance, use, and cancellation of Confined Space permits. Authorization and cancellation for entry into Confined Spaces. And the other elements required by this standard. Other elements of a written program include, but are not limited to, the following; the roles and responsibilities for entry supervisors, entrants and attendants for the permitting process. Refer to the Roles and Responsibilities section of this procedure for specific duties of the various
Procedure No.: WYN032.018 Page: 7 of 25 jobs associated with confined space entry, including entrant, attendant, entry supervisor, owning department and maintenance department. Multi-Employer Coordination BASF is responsible for ensuring that any confined space work done onsite is properly managed as part of the confined space entry work permit process. Prior to work being started, a pre-planning meeting will be held to evaluate the qualifications of all parties involved. In addition, BASF will require a Pre-Task Plan (PTP) prior to any confined space work being initiated. BASF personnel will issue confined space permits for all work performed by BASF owned facilities on the Wyandotte site. Note: A 3 rd party contractor may also issue their own permit to manage the confined space for their personnel. In those situations where a contractor issues their own permit then they are required to also conduct initial air monitoring on their permit. Prior to BASF personnel issuing a confined space permit, a Safe Work Permit will also be issued by the Process Owner; including, documentation of air monitoring results. Due to different work activities in the space, separate Safe Work Permits will be required for each work activity and/or company. The Process Owner is responsible for coordinating entry operations with the Contractor(s), when both BASF and/or multiple Contractor personnel will be working in or near Confined Spaces simultaneously as Authorized Entrants. This coordination is necessary so that employees of one employer do not endanger the employees of any other employer. 4.1.5. Employee Participation Within the BASF Wyandotte site, all Wyandotte s stakeholders and contractors will be involved in the development and implementation of the Confined Space standard. Where contractors are performing work on the Wyandotte site, they will follow both the BASF Wyandotte Site procedure, as well as, the BASF Corporate Confined Space Standards without exception. Information and input on the Wyandotte standard may include any of the following information, including but not limited to, the following: Safety meetings Rescue service drill critiques Employee suggestion programs Accident/incident report investigation follow-up and Training sessions.
Procedure No.: WYN032.018 Page: 8 of 25 4.2 Confined Space Preparation 4.2.1 Cleaning and Decontamination Prior to entry, all Confined Spaces that may have contained a hazardous material or hazardous atmosphere should be cleaned of prior contents by washing, steaming, neutralizing, purging or other effective means to eliminate or minimize the hazard within the space. Work within Confined Spaces that contain contaminated equipment shall be decontaminated in accordance with the Wyandotte Contaminated Equipment procedure in WYN032.046. If product or other material remains in the vessel after cleaning, careful review of the situation by the Owning/Operations department and the maintenance group is required to identify special provisions (e.g., re-cleaning, increased/improved monitoring, additional ventilation, upgrades to or additional PPE requirements). Air monitoring can also be conducted by Operations/Owning personnel who have received training in the following areas: span gas checking, calibration, testing equipment use and data interpretation. 4.2.1 Isolation Techniques The Confined Space shall be completely protected against the release of hazardous energy and material into the space. Every effort should be made to isolate the confined space as close to the vessel as reasonably possible. In the event this cannot be achieved, adjoining piping and equipment must be controlled by using techniques defined in the Wyandotte Control of Hazardous Energy procedure, WYN032.010, including the need to verify that all spaces are free of hazards to the same degree as the space being entered. A line shall be deemed isolated if one or more of the following steps are taken to isolate the Confined Space from potential sources of hazardous materials: A blank or blind has been inserted in the line. Blanks must be of construction and thickness to sustain the maximum line pressure. The line has a double block and bleed where the two block valves are closed, the bleed, in between, is opened and locks/ tags are applied. Lines are disconnected and misaligned from the Confined Space. The block valves in a line to the jackets, coils, reboilers and similar items which in themselves are not open to the confined space in which work is to be performed are closed and tag out applied. The only exception, to not isolate the block valves, would be the use of external cooling water on vessel jackets or coils during hot weather. Lines going to jackets, coils, re-boilers are closed or locked and tagged. Given the fact that the jackets and coils will not leak into the space. At the Wyandotte site all adjoining piping and hazardous energy sources shall be de-energized and isolated in accordance with the Corporate Control of Hazardous Energy Procedure, BC032.014 and the Wyandotte Control of Hazardous Energy Procedure contained in WYN032.010.
Procedure No.: WYN032.018 Page: 9 of 25 Note: If the confined space contains internal power driven mechanisms, such as agitators, all switch gear and other power sources shall be locked, tagged, tried and verified. Look for stored inertial energy of rotating equipment, as well as, hydraulic and pneumatic energy sources. 4.2.3 Preparation and Isolation Requirements Site or Unit spaces that do not meet the definition of a confined spaces, as defined in Section 2.7, are exempt from the Program requirements. Confined Spaces which do not contain a hazard or potential hazard capable of causing physical harm or for which adherence to a requirement would increase the hazard (e.g., blowing air in a dusty environment) may be also be exempted from one or more of the Program requirements. Exemptions must be documented in writing. 1. Exemptions must be reviewed and signed off by the following individuals or groups :Process Owner (or Staff-level designee), 2. Maintenance Team Leader (or designee), and 3. EHS Safety Coordinator (or designee). Note: Standing Confined Space exemptions must be identified and a list maintained by Operations/Owning Unit. 4.2.4 Atmospheric Conditions A. Oxygen Where the level of oxygen is between 19.5% and 21% and the integrity of the atmosphere cannot be guaranteed, an air-line respirator or self-contained breathing apparatus ("SCBA") shall be used. Where the level of oxygen is found to be below 19.5% and corrective actions do not alleviate the situation, a SCBA or pressure-demand air-line respirator with an emergency egress bottle shall be used. Except for rescue, entry into inert atmospheres or atmospheres less than 16% oxygen requires authorization of facility manager or designee and EHS hub representative or designee. B. Enriched Oxygen Atmospheres found to have enriched oxygen supplies (greater than 21%) require appropriate action to reduce the level to 21%. Note: Excess oxygen can extend the flammable range of gases and vapors and can also make combustible materials ignite and burn rapidly.
Procedure No.: WYN032.018 Page: 10 of 25 C. Flammable Gases/Vapors Confined Spaces containing detectable flammable gases/vapors using a properly calibrated and maintained combustible gas indicator operating in the percent range of sensitivity shall not be entered. D. Generation of Flammable Gases/Vapors If work activities to be performed in a Confined Space are expected to generate flammable gases/vapors, continuous ventilation and representative continuous Monitoring are required. If flammable gases/vapors are detected, immediate corrective action must be taken to reduce their concentrations (e.g., increased ventilation and reduced rate of vapor generation). If the combustible gas readings reach 5% of the Lower Explosive Limit (LEL), work must cease and the Authorized Entrants must exit the Confined Space immediately. E. IDLH When entry is made into an IDLH atmosphere or into a space that could quickly develop an IDLH atmosphere (if ventilation fails or for other reasons), the Rescue Service shall stand by at the Confined Space. F. Toxic Substances The level of a toxic substance in the Confined Space should be maintained below the applicable Occupational Exposure Limit (OEL) at all times during the Entry. In those situations where the concentration cannot be maintained below the applicable OEL, appropriate respiratory personal protective equipment shall be used by all Authorized Entrants according to the site/unit Respiratory Protection Program requirements. Note: Concentrations of contaminants may be toxic at levels much lower than flammable gas detection; therefore, the requirements for appropriate PPE for these conditions must also be evaluated and implemented. G. Combustible Dust Confined Spaces containing airborne combustible dust at a concentration that meet or exceed the Lower Flammable Limit (LFL) or obscures vision at a distance of five feet or less shall not be entered. If work activities performed in a Confined Space generate combustible dust at a concentration that obscures vision at a distance of five feet, work activities must cease and immediate
Procedure No.: WYN032.018 Page: 11 of 25 corrective action must be taken to reduce their concentration (e.g., increase ventilation and/or reduce rate of dust generation). H. Physical Hazards Heat, humidity, and cold stress hazards during Confined Space entry shall be controlled to prevent adverse health effects to authorized entrants. I. Radiation Hazards Radioactive devices must be mechanically locked out in the closed/off position by a qualified nuclear gauge operator and checked/verified by a Radiation Safety Officer (RSO) or authorized designee prior to entry into the vessel. J. Other Introduced Hazards When hazardous energy sources are introduced into a Confined Space, the hazardous source shall be controlled or eliminated before entering the confined space (i.e., Hyrdoblasting equipment, heat treating activities, or introduced atmospheric hazards during cleaning). 4.3 Monitoring Requirements 4.3.1 Before Permit Issuance Each confined space shall be initially monitored for oxygen content prior to entry; in addition monitoring for Lower Explosion Limit (LEL) and or toxics is required for spaces that contained a Hazardous Atmosphere. Monitoring shall be performed reflective of entry conditions. Monitoring for atmospheric conditions shall be conducted as close to Entry time as possible and at no time shall it exceed two hours prior to entry. If the space is unoccupied due to work breaks or delays, Monitoring shall be performed as close to re-entry time as possible and at no time shall it exceed two hours prior to re-entry. Various levels or sections of the Confined Space shall be checked to account for oxygen displacement by gases heavier or lighter than air. 4.3.2 Periodic and Continuous Monitoring The atmosphere in the Confined Space shall be monitored continuously during the Entry activities for oxygen when a confined space has had an Atmospheric Hazard or if one may be introduced into the space. The atmosphere in the Confined Space that had an Atmospheric Hazard or if one could be introduced into the space shall be monitored continuously during the Entry activities for flammable gases/vapors
Procedure No.: WYN032.018 Page: 12 of 25 when work activities to be performed in a Confined Space are expected to generate flammable gases/vapors or when the Confined Space has contained flammable gases/vapors. In situations where continuous Monitoring is technically infeasible, pre-determined periodic Monitoring shall be conducted as appropriate. Personal direct-reading monitoring shall be conducted for workers inside the confined space, including BASF and contractor employees. Monitoring parameters should be determined by the Confined Space Entry Supervisor in collaboration with an EHS representative as necessary. Confined Spaces that contain toxic gases/vapors/mists shall be evaluated to determine the appropriate sampling frequency that will accurately assess the atmospheric exposure. 4.3.3 Sequence The atmosphere of all Confined Spaces shall be tested in the following order: a. oxygen content, b. flammable gases/vapors, c. toxic gases/vapors/mists and observation for combustible dusts. 4.3.4 Maintenance and Calibration Monitoring instruments are to be maintained properly and performance tested ( Bump Test or Function Test ) before each day s use, at a minimum. Performance testing shall include verification of proper instrument response against a known concentration of test gas for each oxygen gas, flammable gas/vapor and toxic gas/vapor/mist of concern. Periodic instrument calibration should be performed according to manufacturer s recommendation. 4.3.5 Instrument Tolerances Acceptable instrument performance testing and subsequent Monitoring results may allow for normal acceptable instrument deviations as determined by the instrument manufacturer. 4.4 Confined Space Permit Content The Confined Space Entry permit system shall, at a minimum, include the following information: Identification of the Confined Space and purpose of Entry, Date and authorized duration of Entry, List of Authorized Entrants and Attendants, Name of individual currently serving as Entry Supervisor, Signature/initials of Entry Supervisor who originally authorized Entry, Communication method between attendant and entrants Name or initial of tester
Procedure No.: WYN032.018 Page: 13 of 25 List of the hazards and the isolation and control methods, Acceptable Entry conditions, Identification of Rescue Service and method of communication, Entry equipment required, Monitoring documentation (documented on Wyandotte Safe Work Permit) stated in Section 4.5. of this standard, Other permits required, and An area for additional information/comments 4.5 Documentation Results of air monitoring that indicate the atmosphere the Authorized Entrants actually entered, including oxygen concentration below 19.5% and flammable gases/vapors and toxic materials above zero ppm are considered IH exposure records subject to recordkeeping requirements. Refer to BASF Records Retention Policy BC037 and BASF Exposure Assessment Work Process BWP-008 in Section 6 related documents. Any Confined Space Entry Permit which indicates that personnel actually entered a contaminated atmosphere, must be kept for 30 years as a record of exposure in accordance with the OSHA 29 CFR 1910.1020 (MIOSHA Part 470, Employee Medical Records and Trade Secrets standard). This includes initial entries made by person(s) performing the atmospheric testing. These permits must be kept even if PPE was worn to prevent actual exposure to personnel. Examples of contaminated atmospheres include: Atmospheres containing less than 19.5% oxygen: Atmospheres with a flammable gas/vapor reading greater than zero (0); and Atmospheres with a toxic substance (s) reading greater than zero (0). The Equipment Owner is responsible for reviewing the permits to determine if any should be kept as exposure records per the above described criteria. Applicable permits should be forwarded to the Wyandotte EHS Department for retention. Results and corrections from the annual program review shall be documented and retained until the next review. Results and corrective actions shall be documented from the debriefing at permit close out. The following must be documented on the Confined Space Entry permit: Monitoring instrument calibration verification and equipment identification. Verification of daily performance testing ( Bump Test ). Confined Space atmosphere monitoring results, including the time of the tests and the tester's initials.

Any personnel changes concerning Attendants and Authorized Entrants shall be documented on the permit by an Entry Supervisor. Communications (visual, audio, verbal or signal line) shall be maintained between all individuals involved in the Entry and the Attendant. Where exists, any requirement for special procedures or instructions, shall be noted on the Confined Space Entry permit. These instructions must be compiled prior to the issuance of the Confined Space Entry permit. Any deviations or exceptions to the requirements defined in both the Wyandotte Site Confined or the BASF Corporate Confined Space Standard must be agreed upon by the Process Owner (Operations/Owning group), the Maintenance Team Leader (or designee) and the EHS Safety Coordinator (or designee). If the Confined Space contains internal power driven mechanisms such as agitators, all switch gear and other power sources shall be "locked, tagged and tried" in conformity with the Wyandotte Control of Hazardous Energy Procedure, WYN032.010. Radioactive devices such as level detectors shall be secured to prevent exposure during the Entry in conformity with the Wyandotte Radiation Safety Procedure, WYN032.047. When a portable ladder or stairs are required to enter a Confined Space, the equipment shall be inspected, suitable for the type of space, and, readily available for exit to anyone in the space. All electrical equipment used inside a Confined Space shall be consistent with the Wyandotte Site Hot Work Procedure, WYN032.011 for the area classification in a safe condition and grounded or double insulated. Lighting shall be "approved" low voltage units or extension cords equipped with a functional ground fault circuit interrupter. All temporary lighting shall be equipped with guards to prevent contact with the bulb. 4.7 Confined Space Permit Revalidation If a change in Entry supervision occurs, the on-coming Entry Supervisor must revalidate or reissue the Confined Space Entry permit and inform representative personnel involved in the Entry of the change in supervision. Permit Revalidation includes the review, agreement of permit conditions and signatures of the permit acceptor and Entry Supervisor. Permit Revalidation is not allowed under the following situations: There has been an isolation modification Changes in work scope
Procedure No.: WYN032.018 Page: 15 of 25 A new hazardous energy source is introduced Change in Company performing work Significant time gap as defined by site At the Wyandotte site the permit shall not be valid for longer than one shift of personnel performing the Entry activities (maximum 16 hours). Upon assignment of a new (different shift) Entry Supervisor the permit must be re-validated or reissued and the Permit Acceptor must be informed of the changes. 4.8 Confined Space Permit Closeout and Debrief Upon completion or discontinuation of the Entry, the Confined Space Entry permit shall be returned to an Entry Supervisor for debriefing and closeout. Any issues affecting safe entry conditions identified, including hazards encountered during an Entry will be noted on the debriefing section at the bottom of the Confined Space permit, so that appropriate revisions to the site program can be made as soon as feasible. Authorized Entrants, Entry Supervisor, and Authorized Attendant shall be debriefed concerning the program and any hazards created or confronted during Entry at the end of any Entry operation. The debriefing activities shall be documented on the confined space permit. Completed Confined Space Entry permits shall be retained for the period necessary to facilitate the program review stated in Section 4.13, but should not be kept no longer than one year. Permits do not have to be retained after the review but documentation of the review results and corrective measures is required. 4.9 Duties and Responsibilities 4.9.1 Entrant The Authorized Entrant Responsibilities include but are not limited to: Knowing the hazards that may be faced during entry, including information on the mode, signs or symptoms, and consequences of the exposure; Properly use equipment as required by this procedure, such as, PPE, lighting, and ventilation; Communicate with the attendant as necessary to enable the attendant to monitor entrant status and to enable the Attendant to alert Entrants of the need to evacuate the space; Alert the Attendant whenever: (1) the Authorized Entrant recognizes any warning sign or symptom of exposure to a dangerous situation, or (2) the entrant detects a prohibited condition; Exit from the Confined Space as quickly as possible whenever: (1) an order to evacuate is given by the attendant or the entry supervisor, or (2) the entrant recognizes any warning sign or symptom of exposure to a dangerous situation or (3) the

Rescue Services personnel shall be trained and certified in first aid/cpr and at least one member shall be available at the facility during the Entry with direct means of communication (e.g., radio and telephone) to facilitate a quick response to the Entry location. Non-Entry rescue shall be used whenever possible. When non-entry rescue is not possible due to the space configuration or obstructions, all rescue equipment which would be used in an Entry rescue shall be readily available, at or near the Confined Space Entry area, to reduce the response time. Any Entry into an atmosphere which may be hazardous to retrieve a downed person shall require the use of a supplied-air respirator (SAR) with an emergency egress bottle or a SCBA. 4.11.3 Rescue Team Organization The site rescue team may be comprised of maintenance, production and site services personnel. The Rescue Team Roster is posted on the Wyandotte site Intranet and should also be posted within each respective unit at a location that is accessible by personnel who issue Confined Space Entry permits 4.11.4 Rescue Team Notification Members of the rescue team must be notified that a Confined Space entry is taking place before the entry permit is authorized. A minimum of two rescue team members must be on-site and available for timely response for all Confined Space entries. Any member of the rescue team may be contacted. Solicitation of rescue team members for planned off-shift entries must be performed during the day-shift prior to the off-shift entry. The contracted rescue team member is responsible for advising the Entry Supervisor (Permit Issuer) if more than two members are needed for that entry.
Procedure No.: WYN032.018 Page: 21 of 25 Requests for additional rescue team members may be made by Operations/Owning or maintenance performing the entry. The Entry Supervisor (Permit Issuer) is responsible for contacting all necessary rescue team members to establish a rescue team for that entry. 4.11.5 Rescue Team Communication A method of summoning rescue (i.e., radios, pagers, cell phones, etc.) must be established prior to commencement of entry operations and noted on the Rescue section of the confined space permit. The Confined Space entry attendant will contact the rescue team via the established method in the event that a rescue may be necessary. Drills to practice summoning Confined Space rescue services and also to evaluate response time shall be conducted annually or more frequently to ensure adequate response time is maintained. 4.11.7 Rescue Team Equipment Rescue equipment is contained in the Rescue Team trailer.
