Implementing into everyday engineering procedures, a broad-based understanding of the complex interaction of chemical process technology, mechanical and process design, process control, and Process Safety Management Systems (PSMS) and by virtue of knowledge and experience, evaluate an integrated petrochemical process and:

Identify hazards:

  • Overpressure/underpressure hazards
  • Thermal expansion and brittle fracture hazards
  • Fire and explosion hazards
  • Dust explosion hazards
  • Static electricity hazards
  • Human factors hazards
  • Chemical and reactive chemistry hazards
  • Toxic exposure

Evaluate the risk from those hazards, both qualitatively and quantitatively:

  • Knowledge of previous incidents that have occurred in the company and industry
  • Failure mechanisms that could lead to risks being realized
  • Risk scenarios that should be evaluated
  • Sufficient and effective hazard controls in place or needed
  • Analyze the consequences and probabilities of those risk scenarios
  • Assess the significance of risk posed by those scenarios

Assist in the identification of and evaluation of cost-effective engineering solutions to reduce or mitigate those risks:

  • Remove or reduce the hazard through inherently safer solutions
  • Simplify the process
  • Substitute less hazardous materials for more hazardous materials
  • Operate at less hazardous operating conditions
  • Reduce inventories
  • Reduce the likelihood of risks by providing more or better layers of protection
  • Reduce the consequence of risks by employing mitigating systems
  • Apply Human Factors principles to reduce the error potential at the interfaces of people with equipment and Instrumentation
