2 7.1 REFINERY EVACUATION PROCEDURE Factor EVACUATION FACTORS Description Spill Flow Direction: Refer to SECTION Emergency Personnel Arrival Route: Water Currents, Tides, or Wave Conditions: Injured Personnel Transportation / Directions to the Nearest Hospital: Facility Shelter Location: Route will vary depending on location of Spill. Refer to SECTION N/A Leaving the refinery Main Gate, head west on Stinson Ave. Take Stinson Ave. to Hill Ave., Turn right (north) on Hill Ave. and go to 28 th Street, Turn left (west) on 28 th Street and go to Hammond Ave., Turn left (south) on Hammond Ave. to 34 th St., Turn right (west) on 34 th St. to the Emergency Room entrance of St. Mary s Hospital of Superior Facility is not intended for shelter in place emergencies such as fires, explosions, vapor clouds, etc. When an evacuation is signaled, personnel must recognize and avoid locations downwind of the emergency. Even after the initial evacuation perimeter has been established, it will be necessary to continuously monitor and reassess conditions since changes in the rate and volume of leakage, wind direction, speed, temperature, etc. could drastically alter the perimeter of the safe zone. There are no areas within the refinery that are an adequate distance from process equipment or tanks to be considered Safe Haven Areas, including existing buildings and control rooms. Therefore, all persons except those who are immediately involved in mitigating the incident will evacuate the facility when the evacuation signal is sounded. The prescribed evacuation routes are shown in FIGURE 7.1. Plant personnel have been instructed to take the following steps: Shut off all machinery and be sure equipment is out of the aisles to allow safe passage for other employees. Keep all aisles to exits and to fire fighting equipment free from obstructions at ALL times. Proceed quietly and orderly to the proper fire exit, unless otherwise instructed. REMEMBER, there is always time for an orderly and safe evacuation. Do not return for personal belongings. April 2010 Page 7-2 Technical Response Planning Corporation 2010

3 Upon exiting the facility, MOUSA personnel and contractors are to proceed to the nearest designated Assembly Area via the safest route, depending upon wind direction. Orange wind socks are strategically placed throughout the refinery to identify wind direction. If there is a vapor release, exit the refinery upwind out of the vapor cloud. Assembly Areas are indicated on FIGURE 7.1. Upon arrival at the Assembly Area, report to your supervisor so he/she can account for all his/her employees. Supervisor's will report to the MOUSA supervisory staff upon accounting for all employees. Egress from the Plant should be along main roadways, when possible, and not through process areas. Employees are not to leave the refinery assembly areas until given permission by their supervisor. All employees not assigned a task should remain in the assembly areas until given specific instructions for an assigned task. Upon completion of the assigned task, the employee will return to the staging area or assembly area to await further instructions. The employee will check in with the Staging Area Manager when he/she returns to the staging area. If in a vehicle, park off the roadway, turn off the engine, and leave the keys in the vehicle. Then proceed on foot to the nearest Assembly Area. Contractor and MOUSA supervisors will report to the Supervisor of Administrative Services and will check the head count with the security access system log-in. Supervisors will also provide additional instructions and specify initial isolation and protective action distances, depending on the emergency Procedures for Operating Critical Equipment Prior to Evacuation During an emergency incident, depending on the incident, shut down of certain critical plant operations may be delayed or not shut down at all. Shutdown of any unit or portion of the Refinery requires that the operator of that unit follow the proper procedures to ensure a safe shutdown, or a more severe emergency may develop as the result of an improper shutdown. Procedures are in place for those personnel who remain in the Refinery during an evacuation to monitor these selected plant operations until their evacuation becomes completely necessary. These procedures are included in the individual unit=s operating manuals. March 2006 Page 7-3

4 7.2 SULFUR RECOVERY UNIT EVACUATION PROCEDURE The Sulfur Recovery Unit (SRU) utilizes air monitors to detect the presence of hydrogen sulfide. Detection of hydrogen sulfide causes activation of red flashing lights and a continuous horn. All personnel working in the SRU must evacuate cross wind, then upwind to a safe area until the emergency subsides. 7.3 HF ALKYLATION UNIT EVACUATION PROCEDURE The HF Alkylation Unit utilizes red flashing warning lights to communicate the presence of hydrogen fluoride. These warning lights are manually activated if there is a suspected release. All personnel working in the HF Alkylation Unit must evacuate cross wind, then upwind to a safe area until the emergency subsides. 7.4 SURROUNDING COMMUNITY EVACUATION PROCEDURE The Incident Commander (most senior company official present at the site of the emergency) will assess the impact of the emergency on the community and will direct the main guard gate to notify local fire, police and hospitals if community evacuation is warranted. Initial isolation and protective action distances in all directions and downwind have been developed by the U.S. Department of Transportation (DOT) on the basis of a Gaussian dispersion model. These distances are only evacuation guidelines and protective action distances may be increased depending on circumstances. The Environmental Unit Leader will coordinate downwind air monitoring with the local authorities until the emergency has subsided, and protective action distances will be adjusted, accordingly. If community evacuation is warranted, it will be implemented in accordance with the Community Evacuation Plan developed by Douglas County Emergency Management. Additional procedures related to the alarm/notification system: Portable radios and telephones may also be used during an emergency. During an alarm, visitors will report to their respective MOUSA contact for instructions. 7.5 POST EVACUATION PERSONNEL ACCOUNTING PROCEDURE All personnel should be familiar with the procedures to account for employees after an emergency evacuation has been completed. These procedures are: The Supervisor of Administrative Services is responsible for accounting for all employees after an emergency. March 2006 Page 7-4

5 A written report of the head count will be given to the Incident Commander. The Incident Commander and appropriate agencies will be informed if any person is believed missing. Various personnel may try to account for a missing person. However, an employee will not place himself/herself or someone else at risk through his/her actions. 7.6 EVACUATION TRAINING AND DRILLS Evacuation Wardens All Maintenance Foremen will be trained as Evacuation Wardens to assist in the safe and orderly evacuation of personnel at the Refinery during regular hours. During off hours, Shift Foremen will act as Evacuation Wardens. Evacuation Wardens are trained in the Refinery layout and in the various escape routes available. The responsibility of the Evacuation Wardens are to assist in directing employees from danger locations to safe areas. Evacuation Wardens must also check rooms and other enclosed spaces in the refinery for employees who may be trapped or otherwise unable to evacuate the area. After the desired degree of evacuation is completed, the Wardens are to account for all employees in the safe area. In addition, Evacuation Wardens are made aware of handicapped personnel who may need additional assistance Refinery Personnel All personnel are briefed on evacuation procedures during periodic Emergency Response Plan review sessions.
