  • 2BP: Employees caused deadly blast - Oil company says employee failures led to deaths of 15 people at Texas City, Texas, refinery in March.

    May 18, 2005: 5:41 AM EDT

    TEXAS CITY, Texas (Dow Jones)-- BP PLC (BP) said Tuesday that failures by its employees were responsible for an explosion at its Texas City refinery on March 23, the deadliest industrial accident in 15 years.

    BP Products will take disciplinary action against supervisors and hourly employees who were directly responsible for operating the isomerization unit on March 22 and 23. These actions will range from warnings to termination of employment. As the investigation continues and new information is discovered, others may also be disciplined, the company said.

    "If ISOM unit management had properly supervised the startup, or if ISOM unit operators had followed procedures or taken corrective action earlier, the explosion would not have occurred", said Ross Pillari, president of BP Products North America.

  • 3Accident Summary

    On March 23, 2005, at 1:20 p.m., the BP Texas City Refinery suffered one of the worst industrial disasters in recent U.S. history. Explosions and fires killed 15 people and injured another 180, alarmed the community, and resulted in financial losses exceeding $1.5B. The incident occurred during startup of an isomerization1 (ISOM) unit when a raffinate splitter tower was overfilled; pressure relief devices opened, resulting in a flammable liquid geyser from a blowdownstack that was not equipped with a flare. The release of flammables led to an explosion and fire.

  • 4The Chemical Safety Board

    The U.S. Chemical Safety and Hazard Investigation Board (CSB) final report of the Texas City Explosion was released 3/26/2007- The CSB is an independent federal agency charged with investigating

    industrial chemical accidents- CSB Board members are appointed by the president and confirmed by the

    Senate- CSB investigations look at all aspects of chemical accidents, including physical

    causes such as equipment failure as well as inadequacies in regulations, industry standards, and safety management systems

    - The CSB does not issues citations or fines, but does make safetyrecommendations to plants, industry organizations, labor groups, and regulatory agencies such as OSHA and EPA

    - The CSB Accident Reports and video reconstruction are available on their website, www.csb.gov

  • 5The Baker Report

    Pursuant to an urgent recommendation from the CSB interim report, BP commissioned former Secretary of State James Baker to conduct a third party review of BP corporate practices leading up to the Texas City explosion

    Secretary Baker completed his review January 2007 The Baker Panel focused principally on Process Safety

    rather than personal safety

  • 6Baker Panel Findings

    Corporate Safety Culture- BP Board did not exercise good Process Safety leadership- At Texas City particularly, BP managers did not empower

    employees in the Corporate Safety Culture- BP corporate did not provide appropriate resources to assure

    adequate process safety- BP managers did not incorporate process safety into

    management decision making- BP corporate did not assure a common, unifying Process Safety

    culture among its US refineries

  • 7Baker Panel Findings (Cont.)

    Process Safety Management Systems- BP Process Risk Assessment and Analysis was flawed- BPs US refineries did not comply with its own internal process

    safety standards- BP refineries did not implement good engineering practices- Process safety knowledge and competence was not maintained

    at BP US refineries- BPs corporate process safety management system was

    ineffective and not measurable

  • 8Baker Panel Findings (Cont.)

    Performance Evaluation, Corrective Action, Corporate Oversight- BP measured safety performance through personal injury rate,

    rather than measuring process safety equipment performance- BPs causal analysis methods were inadequate and flawed- The process safety audit system was inadequate- BP managers did not provide timely correction of process safety

    deficiencies- BP corporate oversight of refinery specific process safety

    information was flawed

  • 9CSB Identified Root Causes

    BP Group Board did not provide effective oversight of the companys safety culture and major accident prevention programs.

    BP Senior Executives:- Inadequately addressed controlling major hazard risk, particularly

    process safety performance;- Did not provide effective safety culture leadership and oversight

    to prevent catastrophic accidents;- Ineffectively evaluated safety implications of major organizational

    changes; and- Did not provide adequate resources to its refineries

  • 10

    CSB Identified Root Causes (Cont.)

    BP Texas City Managers did not:- Create an effective reporting and learning culture; i.e. bad news

    was not welcomed (by inference a Just Culture was not achieved either);

    - Effectively investigate accidents;- Hold supervisors and managers accountable for process safety

    performance;- Incorporate good practice design in the operation of hazardous

    chemical systems;- Ensure that operators were supervised and supported during unit

    startup; and- Effectively incorporate human factor considerations in its training,

    staffing and work schedule for operations personnel

  • 11

    CSB Identified Contributing Causes

    BP Texas City Managers:- Lacked an effective mechanical integrity program to maintain

    instruments and process safety equipment;- Did not have an effective vehicle traffic policy to control traffic into

    hazardous process areas or to establish safe distances from process unit boundaries;

    - Ineffectively implemented Pre-Startup Safety Review policy; non-essential personnel were not removed from areas in and around process units during the hazardous unit startup; and

    - Located trailers in close proximity to hazardous operations.

  • 12

    Latent Organizational Weaknesses

    Work environment encouraged procedural noncompliance

    Ineffective communications for shift change and hazardous operations (such as unit startup)

    Malfunctioning instrumentation and alarms Poorly designed computerized control system Insufficient staffing Lack of human fatigue-prevention strategy Inadequate operator training for abnormal and startup

    conditions Failure to establish effective safe operating limits

  • 13

    Latent Organizational Weaknesses (Cont.)

    Ineffective incident investigation management system Ineffective Lessons Learned program No coordinates line management self-assessment process No flare on blowdown drum No automatic safety shutdown system Occupied trailers too close to hazardous operations Key operational indicators and alarms inoperative Ineffective response to serious safety problems and events Focus on injury and illness statistics, not process safety

    - This was an observed Latent Organizational Weakness for their OSHA regulator as well

  • 14

    Latent Organizational Weaknesses (Cont.)

    Poor implementation of Process Hazards Analyses (PHA) and Management of Change (MOC) processes (equivalent to USQ)

    Ineffective follow-up to audit reports Problem reporting not encouraged Inadequate implementation of OSHA Process Safety

    Management regulations Inadequate OSHA inspections and enforcement Gaps in applicable industry standards

    Lessons Learned to DOE Contractors

    Could this really apply to us?

    Do we have higher or lower consequence events?

    What is our relationship with our regulator(s)?

  • 19

    Areas of Similarity

    Aging facilities Safety Culture not well understood with revolving DOE

    contractors Budget limitations Causal Analysis weaknesses Equipment Reliability strategies Uneven quality of written operating and maintenance

    procedures Weak management self-assessment processes Focus on injury and illness statistics

  • 20

    Areas of Difference

    Regulator (DOE) embedded with the contractor organization

    Competent third party oversight (DNFSB) Standardized (and enforced) Process Safety

    Authorization Basis development Parent Organization Oversight Program now required

    in DOE contracts
