According to the Dow U.S. Area Consolidated Audit Program Guidelines and the OSHA Process Safety Management (PSM) standard 1910.119, you must develop an implementation plan as a response to the recommendations. The plan must include the name(s) of the employee(s) assigned to each action item along with an expected and actual completion date for each item. Please note that efforts have been made by the Functional Audit Teams to help prioritize each recommendation. They will be identified as: M = Must Do, (based on compliance issues, government regulations, Dow policies or S&LP) and HR = Highly Recommended, (necessary to mitigate an anticipated or potential hazard). It is the responsibility of the plant/department supervision to communicate the results of the consolidated audit to all employees. Communication must include the results of the Process Hazard Analysis. PHA's include the Reactive Chemicals, Chemical Exposure Index (CEI), Process Safety and Loss Prevention/Fire/Burner Management audit This must be completed within 90 days after the audit report date and documented. Please send your approved implementation plans to Connie Kalencki, Bldg. 3502W by November 7,1997. We will forward a copy to members of the Core Audit Team and the appropriate section to the Functional Team Leaders. Enclosed Audit Recommendations: 1. Process Hazard Analysis 3. Laboratory Audit 5.

Communicate results of the Consolidated Audit to plant personnel within 90 days after the audit report date and document Guidelines For Communicating Process Hazard Analysis (PHA's) To Employees The OSHA Process Safety Management (PSM) Standard (29CFR 1910.119) requires that facilities covered by this standard perform a formal process hazard analysis, communicate the results of this analysis to plant employees whose work assignments are in the process and who may be affected by the recommendations or actions. Currently the LAO Consolidated Audit Process include PHA's (reactive chemical reviews, hazardous materials transportation reviews, chemical exposure index audits, fire & explosive index reviews). The following guidelines can be used to communicate the Process Hazard Analysis (PHA's) to plant employees. Communication to employees may be done in a regular scheduled safety meeting or during a safety training day and documented. REACTIVE CHEMICAL REVIEW: A. Review all worst case scenarios identified by the plant and LAO Reactive Chemicals Committee. Make sure that plant personnel have a thorough knowledge of the reactive chemicals potential. Discuss the safe operating limits and consequences of deviation. Discuss the reactive chemical control systems including hardware, software and procedures. Discuss all other safeguards or action plans that are aimed at avoiding and mitigating the consequences of each scenario. B. Review the recommendations from the LAO Reactive Chemicals Committee and the plant action plans to correct the recommendations. C. Review the results of the employee interviews which are done by the LAO Reactive Chemicals Committee during the Consolidated Audit and the plant follow-up actions to address any deficiencies.

Absolute measures of risk are very difficult to determine, but the CEI system will provide a method of ranking one hazard relative to another. A. Review the list of plant hazardous chemicals that were evaluated by the plant B. Review the worst case scenarios and calculated CEI value. This shall include dispersion data and charts that were developed from the plant CEI review. C. Review all actions required to prevent the worst case. It may be a simple case of reviewing employee job responsibilities from an existing plant emergency drill. Any preventive maintenance, thickness checks. Technology Center recommendations, visual inspections and recommendations from the consolidated audit team should be reviewed also. Action Taken/To Be Taken: Responsibility Richard Rolke Expected Completion Date Actual Completion Date 1/31/98 FIRE & EXPLOSION INDEX: The Fire & Explosion Risk Analysis System is a step-by-step objective evaluation of the realistic fire, explosion and reactivity potential of process equipment and its contents. The purpose of the F&EI system is to: 1) Quantify the expected damage of potential fire, explosion and reactivity incidents in realistic terms. 2) Identify equipment that would be likely to contribute to the creation or escalation of an incident, and 3) Communicate the F&EI risk potential to management. A. Review the plant F&EI process units and classified hazard levels ("heavy", "moderate" etc.). See Table 6, pg. 38 - F&EI Guide, 7th edition. B. Review the list of process units in your plant that were reviewed. C. Review the evaluation of realistic fire, explosion and reactivity potential of the process unit and its contents. (Depending on the level of hazard, certain process equipment spacing, process equipment/piping standards and loss prevention principles are applied to the process to minimize the hazard level).

This is in response to the newly developed audit protocol for conducting Process Hazard Analysis reviews. It involved the use of a new questionnaire which is quite different from the previous one. We appreciate the plant's cooperation in the transition to this new format OPERATING DISCIPLINE Recommendations: M 1. A revision of Section V of the Operating Discipline process, requires the compilation of a package of PHA information to be kept in a permanent plant file.

The recent new superintendent reactive chemical review fulfilled that requirement All concerns that were identified at the new superintendent review have been adequately addressed. The combination Reactive Chemicals/Process Hazard Analysis questionnaire was filled out by Richard Rolke and reviewed by the review team. There are no outstanding issues from the questionnaire. During the "walk-through" inspection, a spot check of the plant's procedures and IPT modules was done. Also, random interviews of the operations personnel were done to check the deployment of reactive chemical knowledge. Recommendations: M 1. The scores from the random interviews of plant employees indicate that the level of deployment of reactive chemical knowledge needs be enhanced. (The testing results are available from Joe Schell).

If a lubricant is necessary to use on a piece of equipment, instrument, or valve component that is in a chlorin containing process str am, what lubricant should be used? Correct SOS Fluorolube, a non-hydrocarbon containing lubricant. 2/2 2/2 2. What is the reactive chemical concern regarding why Vinyl 2 acid is not taken in the P r/Tet plant? Correct Vinyl 2 acid contains acetylene (a hydrocarbon) that will react with chlorine. os aoa 1/2 0/2 3. Why is D-42B rinsed out after burning oil? Hydrocarbons, such as oil, react violently with chlorine. The flushing of D-42B is done to eliminate the risk of chlorine containing feed being introduced into D-42B that would mix with oil left in the tank causing a reactive chemical incident. 4. Why should C-510 be shutdown upon high temperature? To prevent chlorine from getting into the K-520 system, and this in turn resulting in a chlorine-iron fire. 5. What happens when liquid chlorine gets into the Per/Tet reactor? Potential violent reactions. 6. Why are there low pressure trips on D-220? To ensure that there is no back flow of reactor contents into D-220. The reactor runs with an excess amount of chlorine. If the reactor contents were backed up into D-220, the hydrocarbon feeds in D-220 would react with the excess chlorine coming from the reactor. Correct Q SOS 2/2 2/2 Correct SOS 1/2 0/2 Correct SOS 2/2 2/2 Correct OS SOS 2/2 2/2 7 What gas is generated as a result of corrosion on an aqueous HCI tank when there is a leak in the rubber lining?

Why is there a high temperature shutdown on the EDC vent compressors (K-5's)? High temperatures from heat of compression can precipitate a reaction between the ethylene and oxygen in the vents that will result in higher temperatures and fire. Corr ct QS aos 1/2 1/2 10. Why is there a low level trip on the EDC reactors? ' So that there is always enough product to absorb the heat generated by the EDC reactions, and enough liquid height in the reactor bed to keep the reaction from occurring in the vapor space of the reactor. Corr ct Q SOS 1/2 2/2 11. While soda ash can be used on the ground to neutralize acid spills, what happens if soda ash is used to neutralize material in a drum or enclosed container? A reaction in the container that will lead to over pressuring problems. Correct SOS 2/2 2/2 The OS's averaged 78% correct The SOS's averaged 69% correct.
