A systematic method used to identify hazards and operability issues in industrial processes.
HAZOP is a structured and systematic examination of a planned or existing process or operation in order to identify and evaluate problems that may represent risks to personnel or equipment. It helps in recognizing potential safety issues by breaking down complex processes into manageable nodes for detailed analysis. It is commonly used during the design phase but can also be applied to ongoing operations to ensure safety and efficiency.
A HAZOP study was conducted on the chemical reactor process at a manufacturing plant to identify potential hazards such as overpressure, which could exceed the maximum allowable pressure of 1.5 MPa (217 psi).
Commonly used in the chemical manufacturing industry, particularly during the design phase of new plants or processes to ensure all potential hazards are assessed before construction begins.
In the petrochemical sector, HAZOP studies are used to assess the potential risks associated with the transportation of hazardous materials like liquefied natural gas, ensuring that all transfer systems adhere to the regulatory specifications of API RP 752.
Regularly applied in petrochemical industries to maintain safety standards in ongoing operations and to evaluate new transportation methods.
