1. OSHA Process Safety Management Program
Chemical and Refinery
National Emphasis Programs

2. Emphasis Programs
OSHA Emphasis Program (NEP) address hazardous industries or operations for targeted inspections.
Programmed inspections will take place in all Regions in facilities that are known to OSHA.
Un-programmed inspections will also be conducted in all OSHA Regions.

3. CHEMICAL PSM NEP
Purpose: Prevention or minimization of the consequences of catastrophic releases of toxic, reactive, flammable, or explosive chemicals

4. PSM STANDARD (1910.119) Application
A process which involves a chemical at or above the specified threshold quantities listed in Appendix A (136)
A process which involves a flammable liquid or gas (defined in (c)) on site in one location, in a quantity of 10,000 pounds ( kg) or more (with some exceptions).

5. PSM NATIONAL EMPHASIS PROGRAM
PSM Refinery NEP
OSHA initiated the Refinery NEP in 2007 to address catastrophic releases of highly hazardous chemicals at refineries (SIC 2911)
Region VI conducted approximately 32 refinery NEP inspections over the next three years.
The large number of fatal or catastrophic incidents in the petroleum refining industry dictated the need for a national emphasis program.
Included 52 employee deaths and 250 employee injuries, 98 of these injuries required hospitalization.
OSHA promulgated the PSM standard in 1992 in response to a number of catastrophic incidents that occurred worldwide (see Process Safety Management of Highly Hazardous Chemicals; 29 CFR ).
These incidents spurred broad recognition that handling highly hazardous chemicals could lead to incidents that may occur relatively infrequently, but, due to their catastrophic nature, often result in multiple injuries and fatalities.

6. NEP Targeting Sources OSHA will use four sources for targeting
U.S. EPA Chemical Accident Prevention Provisions, RMP 3
Explosives manufacturing NAICS codes
OSHA’s IMIS database
OSHA Area Office knowledge of local facilities.

7. Site Selection 3-5 inspections per Area Office per year.
In Region VI we will also performing 6 refineries.
OSHA will also use the Chem NEP inspection framework to conduct incident investigations (fires/explosions fatalities and catastrophes)
Based on their familiarity with local facilities, ROs and AOs shall add or delete facilities as necessary.
Random Selection

8. Selection of Unit
A PSM-covered process or processes shall be selected for evaluation for compliance with the standard. For large continuous processes, a portion of the covered process may be selected, for example, a unit operation within the covered process.
More than one unit may be selected if it is deemed necessary to get a representative sample of the facility’s covered processes based on the size and complexity of the facility.
Often the most hazardous process is selected; however, discretion can be used in choosing the Selected Unit.

9. Ammonia One of the Categories will include
Category 1 –Facilities likely to have ammonia used for refrigeration
Category 2 – Facilities likely to have chlorine used for water treatment as the only HHC;
Category 3 – Facilities likely to have both ammonia and chlorine, ammonia or chlorine used for other than refrigeration or water treatment, or HHCs other than ammonia
or chlorine.

10. PSM STANDARD Process Safety Information (PSI)
Process Hazard Analysis (PHA)
Operating Procedures
Pre-startup Safety Review
Mechanical integrity
The compilation of written process safety information used by the employer/employees to identify and understand the hazards posed by those processes involving HHCs. PSI shall include information pertaining to the hazards of the process, the technology and equipment in the process. The PHA hazard analysis (hazard evaluation) shall identify, evaluate, and control the hazards involved in the process.

11. PSM STANDARD Contractor Evaluation/Performance Management of change
Incident investigation
Emergency planning and response
Compliance Audits
Contractors:
Safety performance evaluation
Inform the contractor of the potential hazards
The emergency action plan
Entrance and exit of contract employees
Contractor illness and injury log
Pre-start-up Review
Construction and equipment is in accordance with design specifications
Safe operating procedures, emergency procedures are in place and adequate
Mechanical Integrity
Pressure vessels and some storage tanks, piping system, relief/vent system, emergency shutdown system, controls, pumps
Training
Inspection and testing
Equipment deficiencies
Quality assurance
Management of change -except for in-kind changes
Incident investigation -The employer shall investigate each incident which resulted in, or could reasonably have resulted in a catastrophic release of highly hazardous chemical in the workplace.
Compliance Audits -certification every three years

12. Chemical NEP Inspection Plan
OSHA to inspect host and contract employers
Contractors (including subcontractors) working on or adjacent to the Selected Unit
OSHA will use the applicable questions in the dynamic list to evaluate contractor compliance
Includes construction contractors working on or adjacent to the Selected Unit(s)
Inspection emphasis on implementation over documentation.

13. Selection of Unit OSHA shall select a PSM-covered process
For large continuous process, OSHA may select a portion of the covered process (the Selected Unit(s))
Selection will be based on factors such as:
Risk of releasing flammables and toxic substances
Operating pressures/temperatures
Quantity of chemicals present
Incident reports and other history
Age of the process unit
Employee representative input

14. Chemical NEP Outreach
OSHA will develop chemical plant PSM information and training materials.
OSHA has performed outreach activities that will support the enforcement efforts.
Outreach products and activities include: letters and news releases, seminars on chemical plant process safety topics, coordination with OSHA’s cooperative program participants, including VPP, Strategic Partnerships, and Alliances.

15. Process Safety Management Accident Investigation Scenario

16. XXX Incorporated
Gas Plant-vessel overpressure gas release ignited by an undetermined source initiating large fire
Plant operators attempted to shut down the plant by activating the emergency shutdown system; but without success
Emergency shutdown device (one button) did not work
Plant operator and contractors evacuated the plant
Fire continues for several hours; but fire extinguishing is not proposed due to explosion hazard and risk involved

17. XXX Incorporated
Small Volunteer Fire Department and local sheriff responded to fire
Plant staff and first responders monitor the event from a safe distance; from the Incident Command Center
Plant manager requests volunteers and four plant staff volunteer to enter the facility and close manual activated valves controlling the inlet pipe line entering the plant
Firefighters recommend that personnel not enter the plant due to the hazardous conditions and possibility of an explosion
However, employees enter anyway without help from the fire dept.

18. HAZWOPER REQUIREMENTS
(q)(1) An emergency response plan shall be developed and implemented to handle anticipated emergencies prior to the commencement of emergency response operations. The plan shall be in writing.
Employers who will evacuate their employees from the danger area when an emergency occurs, and who do not permit any of their employees to assist in handling the emergency, are exempt from the requirements of this paragraph if they provide an emergency action plan in accordance with 29 CFR
(q)(2)(i) The employer shall develop an emergency response plan for emergencies which includes pre-emergency planning and coordination with outside parties.
, decontamination, distribution, deployment sites, and vessels of opportunity (VOOs).

19. YYY incorporated
Food Manufacturer-maintenance employee working on valve on a vessel breaks valve resulting in the release of carbon dioxide in Room-6 within a building.
Maintenance employee goes to control room to inform operator that there is a CO2 leak in Room-6
CO2 alarm alarms indicating a CO2 level of at least 3.0 %
Operator informed shift supervisor who then told the operator he was headed to the room and to have someone bring him an SCBA-respirator
Plant evacuation was issued by the facility-plant manager
3.0 % equals 30,000 ppm
PEL is 5,000 ppm
IDLH 40,000 ppm
CO2 alarm does not register levels above 3.0 percent

20. YYY Incorporated
Maintenance personnel brought the SCBA to the room but could not find the shift supervisor.
Unit manager instructed employees to assemble fire brigade for search and rescue and to notify fire department.
Fire Department finds shift supervisor motionless on sixth floor; removes him from the area and attempts to revive him without success.
With assistance of plant employee, fire department enters an area adjacent to Room 6 and shuts off valve stopping release of CO2.
OSHA personnel made over 4,200 site visits, covering staging areas, decontamination, distribution, deployment sites, and vessels of opportunity (VOOs).

21. HAZWOPER REQUIREMENTS
(q)(3)(iv) Employees engaged in emergency response and exposed to hazardous substances presenting an inhalation hazard or potential inhalation hazard shall wear positive pressure self-contained breathing apparatus while engaged in emergency response, until such time that the individual in charge of the ICS determines through the use of air monitoring that a decreased level of respiratory protection will not result in hazardous exposures to employees.
(q)(3)(v) The individual in charge of the ICS shall limit the number of emergency response personnel at the emergency site, in those areas of potential or actual exposure to incident or site hazards, to those who are actively performing emergency operations. However, operations in hazardous areas shall be performed using the buddy system in groups of two or more.
