Q

Process Safety Information

A
  • Must be compiled and made available to all employees
  • Includes toxicity, permissible exposure levels, process chemistry, safe operating limits
  • detailed process design information
  • consequences of deviations are also required

Q

Process Hazards Analysis (PHA)

A
  • Evaluation of potential causes and consequences of a safety incident
  • Evaluation by a team of experts
  • Uses generally accepted methodologies such as HAZOP, What-if, fault trees etc.
  • PHA updated at least every 5 years
17
Q

Operating Procedures

A
  • written procedures developed, implemented, and maintained
  • Covers startup, normal, temporary, and emergency operations, normal and emergency shutdown, precautions, quality specifications, control systems and functions
  • safe work practices (hot work, lockout/tagout, confined space work)
18
Q

Training

A
  • Programs to train employees about hazards
  • Refresher training every 3 years
19
Q

Contractors

A
  • Must have skills necessary to perform work safely
  • They must be informed of all hazards related to the work and the emergency action plan
20
Q

Pre-startup Safety Review

A
  • Special safety review after modification to the process or operating conditions (before startup) to ensure equipment meets design specifications, procedures and training has been implemented, and hazard analysis recommendations have been addressed.
21
Q

Mechanical Integrity

A
  • ensure equipment, piping, relief systems, controls, and alarms are mechanically sound and operational
  • written procedures for maintenance
  • preventative maintenance training
  • periodic inspections and testing
  • procedure for corrections
  • process for evaluating equipment and spares are sufficient
22
Q

Hot Work

A
  • hot work activities include: welding, grinding, using spark-producing equipment
  • requires authorization dates, equipment involved, hazard analysis, signatures, etc.
23
Q

Management of change (MOC)

A
  • manage changes in process chemistry, raw material, process equipment, and operating procedures
  • ensure that changes to processes are properly analyzed, documented, and communicated to employees
  • ensures that changes to a process do not introduce new hazards or increase existing hazards
24
Q

Incident investigation

A
  • Each incident that resulted in, or could reasonably have resulted in, a catastrophic release of a highly hazardous chemical must be investigated
  • This investigation must begin no later than 48 hours following the incident
25
Q

Emergency planning and response

A

Required employee plan to respond effectively to the release of highly hazardous chemicals

26
Q

Compliance audits

A
  • certification of compliance required every 3 years
  • address all areas of PSM
27
Q

Trade secrets

A

Secrets must be made known to employees if this information is needed to meet PSM responsibilities, but may be protected under confidentiality agreements

28
Q

Tesoro Anacortes Refinery Disaster

A

A heat exchanger shell failed catastrophically which resulted in 7 fatalities

29
Q

EPA

A

Environmental Protection Agency

30
Q

What does the EPA do?

A
  • published the risk management program (RMP) in 1996, also in response to Bhopal
  • designed to decrease number and magnitude of accidental releases of toxic and flammable substances
  • documentation is shared with regulatory agencies and local community
31
Q

What are the 3 components of EPA RMP?

A

Hazard assessment, prevention program, emergency response program

32
Q

What is the difference in the OSHA PSM and the EPA RMP

A

Process safety management is designed to protect on-site individuals, whereas the risk management plan is designed to protect off-site individuals and the environment

33
Q

EPA RMP: Hazard Assessment

A
  • consequence analysis for potential releases
  • includes “worst-case” scenario and more likely but significant accident scenario
  • typically a risk matrix
  • worst-case scenario based on releasing the entire contents of a vessel or piping system in a 10-minute period under worst-case meteorological conditions
  • only consequence, not probability
34
Q

EPA RMP: Prevention Program

A
  • 12 elements
  • Substantial overlap with PSM’s 14 elements
35
Q

EPA RMP: Emergency Response Program

A
  • steps to be taken by employees in response to accidental release
  • procedures for notifying the community and emergency response agencies
  • emergency drills required
36
Q

Chemical Facility Anti-Terrorism Standards (CFATS)

A
  • US department of Homeland Security also has regulations and standards
  • Chemical facility anti-terrorism standards
37
Q

What is the purpose of the CFATS?

A

Identify all chemical facilities of high-risk with respect to terrorism and ensure these facilities have an effective security risk management plan
- Security concerns: intentional loss of containment, theft of chemicals, contamination of product/process, degradation of the assets, acquisition of chemicals under false pretense
