HAZOP is a structured and systematic examination of complex, planned, or existing processes or operations used to identify and evaluate problems that may represent risks to personnel equipment.
HAZOP (Hazard and Operability Study) systematically identifies possible hazards in a system, identifying operability problems likely to lead to nonconforming products.
HAZOP is designed from the theory that risk events are caused by deviation from design or operating intentions.
The process is broken down into its constituent steps, and every variation of system elements is considered, to see what could go wrong.
As the old proverb goes:
"An ounce of prevention is worth a pound of cure"
When thinking about hazards in the workplace, this statement rings true. According to the International Labour Organization, we are in an occupational safety and health crisis, costing the global economy $1.25 trillion.
Who pays for hazard and risk assessment neglect?
By following this checklist, you will implement a thorough, orderly, and systematic approach to identify, evaluate, and control the hazards of workplace processes.
Deviations from operating intentions are identified by using a set of guide words as a systematic list of deviation perspectives. This is a unique feature of the HAZOP assessment.
How to use this checklist
At the beginning of this checklist, you will be presented with a set of specialized questions given as form fields. You are required to populate each form field with your data.
A Hazard and Operability Study systematically investigates each element in a process, with the goal of finding potential situations that would cause that element to pose a hazard or limit the operability of the process as a whole.
The process of HAZOP is split into four basic steps:
- HAZOP team formation
- Identification of elements in the system
- Consideration of possible variations in operating parameters
- Identification of hazards or failure points
At the end of each stage, your supervisor/manager will review your work using Process Street's approvals feature. The resulting information is then used to make system improvements. The best way to apply the results will depend on the nature of the system.
Features used in this template include:
- Stop tasks - To ensure task order.
- Dynamic due dates - To make sure your initiative is reviewed on time.
- Role assignment - To delegate tasks within your team ensuring your supervisors are appropriately assigned to the review tasks.
- Approvals - Tasks can be accepted, rejected, and rejected with comments.
