The Oil and Gas facilities, Refineries, Chemical/ Petrochemical Plants, Manufacturing Facilities, etc., do keep a disciplined framework for managing the integrity of the operating systems and processes that handle hazardous substances that when released, impact safety, environmental damage and business losses; this is Process Safety.
From OSHA, "Process Safety Management"; "Unexpected releases of toxic, reactive, or flammable liquids and gases in processes involving highly hazardous chemicals have been reported for many years, in various industries using chemicals with such properties. Regardless of the industry that uses these highly hazardous chemicals, there is a potential for an accidental release any time they are not properly controlled, creating the possibility of disaster".
Process Safety deals with the prevention and control of events that have the potential to release hazardous materials and energy. Most major incidents that happened in the industry were initiated by hazardous release; accidental or as a result of structural failure.
Vestiro works with specialized partners to conduct appropriate studies to identify all potential sources of hazardous materials and energy release; and then recommend the appropriate mitigation for each source.
Vestiro Consultants are available to independently review your engineering design; or as part of an engineering task force, to help identify all SID issues, and recommend the appropriate mitigation for them.
Process Hazard Analysis: A PHA is directed toward analyzing potential causes and consequences of fires, explosions, releases of toxic or flammable chemicals and major spills of hazardous chemicals, and it focuses on equipment, instrumentation, utilities, human actions, and external factors that might impact the process
Hazard Identification - a qualitative technique for the early identification of potential hazards and threats effecting people, the environment, assets or reputation.
Hazards and Operability - as a form of PHA, is a structured and systematic examination of a complex planned or existing process or operation in order to identify and evaluate problems that may represent risks to personnel or equipment.
Layers Of Protection - as extension of HAZOP studies: allows the safety review team an opportunity to discover weaknesses and strengths in the safety systems used to protect employees, the plant, and the public. LOPA is a means to identify the scenarios that present the most significant risk and determine if the consequences could be reduced by the application of inherently safer design principles. LOPA can also be used to identify the need for Safety Instrumented Systems (SIS) or other protection layers to improve process safety, and to meet the requirements of standards such as ANSI/ISA-84.00.01. Safety Objective Analysis (SOA) is also covered.
Safety in Design (SID) is about integrating hazard identification and risk assessment methods early in the design process, to eliminate or minimise risks of injury throughout the life of a facility; operability, maintainability, accessibility, and emergency evacuation are all covered.
Job Safety Analysis (JSA) is a safety procedure that can be used to define and control hazards associated with a certain process, job, or procedure. It is a systematic examination and documentation of every task within each job family to identify health and safety hazards, and the steps to mitigate the occurrence of the hazard.
