2 OVERVIEW CONGRESSIONAL HEARINGS CRITICIZING OSHA OSHA S RESPONSE TO CRITICISM TWO NEP S WEST FERTILIZER REFINING NEP ENFORCEMENT STATISTICS CHEMICAL NEP Overview Chemical NEP Enforcement Statistics LESSONS LEARNED FROM PSM CITATION PATTERNS INDUSTRY STANDARDS CITED MOST FREQUENTLY OSHA INTERPRETATION LETTER ON THRESHOLD QUANTITIES RECOMMENDATIONS 2

3 CONGRESSIONAL HEARINGS ON BP DISASTER MARCH 22, 2007 Chairman Miller Is OSHA doing its job? OSHA has failed to protect workers BP is the story of the failure of OSHA OSHA s penalty structure is ineffective Congressman Holt OSHA is the lap dog of the industry 3

4 KEY WITNESS AT THE CONGRESSIONAL HEARINGS Carolyn Meritt Chairperson of CSB OSHA s regulatory oversight was ineffective Rigorous enforcement of PSM would have prevented this incident OSHA has few trained inspectors. All witnesses agreed Chemical Industry and Refining Industry have similar safety issues. 4

5 OSHA S RESPONSE TO THE CRITICISM Two National Emphasis Programs Released in June 2007 Refining NEP Released in July 2009 Pilot Chemical NEP Released in November 2011 Chemical NEP Interpretation letters pulled from OSHA s website New interpretation letters and aggressive enforcement to expand PSM coverage More PSM trained compliance officers 5

6 CRITICISM SURROUNDING THE WEST FERTILIZER Numerous New Articles OSHA does not have the resources. OSHA and state plans have 2,000 inspectors for 8 million workplaces or once every 131 years. OSHA s penalties are too low. Congressional hearings Potential legislation Increased enforcement by OSHA 6

29 Summary of OSHA s Chemical NEP Pilot Program has ended. National Program started in November Applies to chemical plants subject to PSM. Applies nationwide to all OSHA regions and state plans. State plans must implement the chemical NEP within 6 months or develop one that is at least as effective. 29

30 Chemical NEP Programmed and Unprogrammed Inspections Programmed inspections under this NEP shall be randomly selected sites from the Region s revised lists 3-5 programmed inspections per Area Office per year (52 Area Offices) Unprogrammed inspections: other triggers for a Chemical NEP inspection: Accident Catastrophe Complaint Referral Site-specific targeting plan 30

31 Chemical NEP Dynamic Lists CSHO s should verify the implementation of PSM elements to ensure that the employer s actual program is consistent with their written program. Three OSHA inspection protocols called Dynamic Lists : PSM General Ammonia Refrigeration Chemical Processing These lists will be periodically updated and are not available for public review 31

32 Chemical NEP Prior PSM Citations: Abatement Requirement During the course of the inspection, the CSHO shall review abatement for all PSM citations issued within the previous 6 years to determine whether the hazard still exists. If a hazard exists, the CSHO shall determine whether there has been a failure to abate in accordance with CPL FOM, and issue a notice for failure to abate as appropriate. FTA penalties can be up to $7,000 per day per violation. 32

33 Chemical NEP Staffing and Duration of Inspection Usually 1-2 compliance officers Inspectors must take specialized PSM training classes 134 man hours for Chemical NEP inspection (includes preparation, opening, site work and drafting citations and reports) 25 man hours for average OSHA inspection 1000 man hours for Refining NEP inspection 33

57 LESSONS LEARNED FROM PSM CITATION PATTERNS OSHA s aggressive interpretations of PSM standard OSHA s selective interpretations of RAGAGEP OSHA demands documentation for PHA, audit and incident investigation findings. Citation patterns show OSHA s PSM priorities 57

58 OSHA S AGGRESSIVE INTERPRETATIONS Piping and Instrumentation drawings Applying steam constitutes a change Covering mixtures of less than 10,000 lbs of flammables under the PSM standard. Facility siting: Determining that 1 in 100 million years risk basis for a willful citation. Required to keep PHA documentation from 1994 and

61 CHEMICAL NEP MOST FREQUENTLY CITED NON-PSM CITATIONS Electrical Safety Respirators Lockout/Tagout Subpart D - Walking/Working Surfaces Machine Guarding 61

62 CHEMICAL NEP MOST FREQUENTLY CITED NON-PSM CITATIONS Electrical Working space around equipment was not kept clear Covers for electrical installations were not secured/all unused openings were not effectively closed Improper grounding Flexible cords and cables were used as a substitute for fixed wiring Unclassified electrical equipment was used in a classified area Defective electrical equipment was not removed from service Proper electrical protective equipment was not provided where necessary (FR clothing, face shields, NFPA 70E considerations for arc flash) 62

63 CHEMICAL NEP MOST FREQUENTLY CITED NON-PSM CITATIONS Respirators Employer failed to determine a reasonable estimate of employee exposure to respiratory hazards Written respiratory protection program was not in place when respirators were necessary Medical evaluations were not provided before employees were fit-tested or required to use respirators Fit-testing was not provided prior to initial use of the respirator Employees did not receive training before being allowed to use tight-fitting respirators Respirators were not cleaned and disinfected as often as necessary to be maintained in a sanitary condition 63

64 CHEMICAL NEP MOST FREQUENTLY CITED NON-PSM CITATIONS Lockout/Tagout Failure to develop, document, and utilize written lockout procedures for specifically identified equipment Lockout/tagout devices did not meet the requirements of (c)(5) identify employee, tagouts must be nonreusable, etc. Periodic inspections of the lockout/tagout procedures were not completed Lockout/tagout training was deficient where each employee had his own way of locking out Lockout/tagout procedures were not implemented as required employees failed to follow the procedures In group lockout scenarios, each employee failed to affix his own lockout device 64

65 CHEMICAL NEP MOST FREQUENTLY CITED NON-PSM CITATIONS Subpart D Walking/Working Surfaces Ladderways and platforms were not adequately guarded Wall openings over 4 feet from the level below were not adequately guarded Open-sided floors and platforms over 4 feet from the level below were not adequately guarded 65

66 CHEMICAL NEP MOST FREQUENTLY CITED NON-PSM CITATIONS Machine Guarding Inadequate guarding for: Drill presses Fans Augers Saws Conveyors Grinders Lathes Shafts and shaft ends Milling machines Chains and belts 66

67 Regulatory Update: May 21, 2009 Kaster Letter PSM - Calculating TQ s Question: Is the total mass of a mixture consisting of a fine, non-soluble, non-combustible solid combined with a flammable liquid considered when determining if a threshold quantity (TQ) is present in a process? Rationale: If the mixture as a whole meets the 29 CFR (c)(iii) definition of a flammable liquid, then the total amount of flammable liquid is 10,000 pounds, even if some components(s) of the mixture alone would not meet the required flash point. Answer: Because the mixture in question meets the definition of a liquid and has a flashpoint of less than 100 F, it is a flammable liquid. A process containing 10,000 pounds or more of the mixture would be covered under the PSM standard. 67

68 RECOMMENDATIONS First Recommendation Use of the Citation Data Auditing Preparing for inspections Settlements and potential repeat citations Due diligence 68

69 RECOMMENDATIONS Second Recommendation Review prior citations for PSM violations Go to osha.gov Check OSHA s records on citations for PSM violations Gather documents to show abated Audit to ensure not recurring Third Recommendation Do the Unit selection analysis for the most hazardous process 69

70 RECOMMENDATIONS (cont d) Fourth Recommendation Conduct an Audit of Selected Unit 70

71 RECOMMENDATIONS (cont d) Traditional Safety Focus include in Unit audit Electrical LOTO PPE Guarding Respirators Walking/Working Surfaces Consider whether you want to do audit under privilege. See case where we successfully defended a claim of attorney privilege for a gap analysis under Refining NEP. 71

72 RECOMMENDATIONS (cont d) Fifth recommendation: Train a team to manage the inspection Sixth recommendation: Interview disgruntled employees 72
