Title: Process Safety Management

Process SafetyManagement
. and its Impact on the Professional
Engineering Community

  • Process Safety Management is a comprehensive
    framework of activities for managing the
    integrity of a hazardous (chemical) operation.
    Its goal is to eliminate (prevent and mitigate)
    loss of containment incidents.

Loss of containment events can lead to fire,
explosion or toxic effects and may result in
large numbers of casualties.
Occupational Health and Safety
Process Safety
  • Workplace rules
  • Worker training
  • Supervision
  • Individual behaviors
  • Safety equipment
  • Focus on individual well being
  • Collective commitment
  • Addresses events over which the individual worker
    has little or no control
  • Focus on systems
  • Broader impact events that could affect groups
    of workers or general public

Early Development
  • Process Safety concepts were first adopted by
    companies that specialized in the production of
    highly hazardous chemicals (DUPONT, ICI).
  • 1984 Bhopal, India chemical plant incident
    released toxic gas into local community causing
    the deaths of 3000 people.
  • Analysis indicated the accident was preventable
    through formal management systems.
  • Industrialized nations formally adopted Process
    Safety Management.

PSM Protocols
  • Several PSM protocols exist worldwide.
  • OSHA 1910.119 (US) is legislated and requires
    designated operations to comply with provisions
    of 14 element framework.
  • Center for Chemical Process Safety (industry
    alliance) recently developed a 20 element risk
    based framework that better addresses people,
    process and equipment issues.
  • PSM element framework should be tailored to type
    of operation.

Canadian Requirements
  • No formal PSM regulation per se.
  • CEPA 1999, section 200 (Environment Canada)
    mandates the development and implementation of
    emergency response plans for environmental
    emergencies in designated high hazard industries.
  • Bill C-45 (Westray bill) includes amendments to
    the criminal code of Canada.
  • Legal duty for all persons directing work to take
    reasonable steps to ensure the safety of
    workers and the public.
  • Severe penalties for failing to ensure safety and
    integrity of operating facilities.

PSM Structure
  • Each of the 20 elements of Risk Based Process
    Safety is fully described in the CCPS Guidelines
    book Guidelines for Risk Based Process Safety,
    Wiley, 2007, ISBN 978-0-470-16569-0.
  • A better understanding of process safety may be
    acquired through a participative workshop with
    other professionals.

Engineering Discipline Involvement
  • Process selection
  • Operating conditions
  • Safe operating envelope
  • Process design
  • Process control
  • Safeguards
  • Monitoring

Why Process Safety Management?
  • PSM framework is essential to avoidance of loss
    of containment incidents these can put a
    company out of business
  • PSM drives rigor and discipline into an operating
  • An effective PSM framework will also address
    smaller incidents including those not associated
    with loss of containment
  • PSM will improve the bottom line

Executive Support
Executive support is required in the following
areas to ensure PSM success
  1. Financial additional resources (people and
    money) required for PSI, PHAs, training,
    maintenance etc.
  2. Production penalty may need to suspend
    production if warranted by serious process safety
  3. Hold organization accountable engage in
    discussions with operations personnel about
    process safety issues. Ask questions
