2 1 BLRs Safety Training Presentations Process Safety Management of Highly Hazardous Chemicals 29 CFR (PSM)

3 2 Disasters That Led to Process Safety Management n Bhopal, India (1984) 2,000 deaths Isocyanate release n Pasadena, Tex. (1989) 23 deaths, 132 injuries Petroleum explosion n Cincinnati, Ohio (1990) 2 deaths Explosion n Sterlington, La. (1991) 8 deaths, 128 injuries Chemical release

4 3 Clean Air Act Amendments1990 n Required secretary of labor to promulgate a PSM standard n PSM standard must include a list of highly hazardous chemicals n Highly hazardous chemicals list must include: toxics, flammables, highly reactive and explosive materials n Required EPA to establish RMP standard

5 4 Minimum Program Requirements n Written safety information n Workplace hazard assessment n Consult with employees n Establish a system to respond to findings n Periodic review of assessments and response n Written operating procedures n Safety training and operating information

6 5 Minimum Program Requirements (cont.) n Appropriate information and training for contractors n Train and educate employees in emergency response n Establish a quality assurance program n Establish maintenance systems n Prestart-up safety reviews n Management of change n Incident investigation

7 6 Application of PSM n Companies that process highly hazardous materials n Flammable liquids and gases in quantities in excess of 10,000 pounds

8 7 Initial Process Hazard Analysis Deadlines n 25% complete by May 26, 1994 n 50% complete by May 26, 1995 n 75% complete by May 26, 1996 n 100% complete by May 26, 1997

9 8 Process Safety Information n Toxicity n Permissible Exposure Limits n Physical Data n Reactivity Data n Corrosivity Data n Thermal and Chemical Stability Data

10 9 Process Technology n Block flow diagram or process flow diagram n Process chemistry n Maximum intended inventory n Upper and lower limits n Consequences of deviations

11 10 Information on Process Equipment n Materials of construction n Piping and instrument diagrams (PIDs) n Electrical classification n Relief system design n Ventilation system design n Design codes n Material and energy balances n Safety systems

12 11 Items the PHA Must Address n Hazards of the process n Identification of previous incidents n Engineering and administrative controls n Consequences of failure n Facility siting n Human factors n Qualitative evaluation of safety and health effects

13 12 Operating Phases n Initial start-up n Normal operations n Temporary operations n Emergency shutdown n Emergency operations n Normal shutdown n Start-up following turnaround

14 13 Operating Limits n Consequences of deviation n Steps required to correct or avoid deviation

15 14 Safety and Health Considerations n Properties and hazards of the chemicals n Precautions to prevent exposures n Control measures to be taken n Quality control for raw materials/control of inventory n Special or unique hazards n Safety systems and their functions

16 15 Management of Change n Technical basis for the proposed change n Impact of the change on safety and health n Modifications of the operating procedures n Necessary time period for the change n Authorization requirements for the change

17 16 Training Requirements n Initial training Prior to work assignment Waved for those already in a process n Refresher training Every three years n Training documentation

18 17 Contractor Requirements n PSM applies to contractors in or adjacent to a process performing Maintenance Repair Turnaround Major renovation Specialty work n PSM does not apply to incidental contractors Food service Laundry Delivery, etc.

19 18 Incident Investigation Reports n Date of incident n Date investigation began n Description of the incident n Factors contributing to the incident n Recommendations resulting from the investigation
