The hazard analysis should result in a written report documenting the hazards found, and provide recommendations for controlling those hazards, along with a schedule for when controls will be implemented.
The report should include documentation of any actions that were taken, and how the changes will be communicated to various stakeholders such as the operations, maintenance, and safety departments.
OSHA has a list of hazard analysis methods they deem acceptable. The basic information this team is provided with includes:. Applying the principles of gemba the team goes to the field and walks down the process, and talks with the people who are involved in operating and maintaining the process equipment.
What if fluid viscosity should exceed the specification? What if the bearing cooling water pump fails? They look at the entire process from the receipt of raw materials through the delivery of the finished product to the customer.
The result is a list of possible hazard conditions along with recommended actions that can be taken to protect against undesirable outcomes. A checklist hazard analysis begins with an existing safety checklist. It may have been created by an individual, or be the result of a previous hazardous analysis. A typical checklist includes items such as:. The team goes through the checklist item by item, to stimulate questions about the process and possible hazards.
The final result is a set of questions about possible hazards. The team discusses these, reaching agreement on what is truly hazardous.
They develop a list of recommendations for eliminating or protecting against those hazards and may recommend extended research of some of the questions. A Hazard and Operability Study HAZOP systematically identifies all of the ways in which operating conditions can deviate from the intended design, with the result being a safety hazard or an operating problem.
A team of experienced people, who are familiar with the process brainstorm potentially hazardous situations. Home : Conference Presentations. Attention eLearning Users We are upgrading our learning platform! Checkout Checkout Do you already own this? April 3, Share This Post:. The purpose of Process Hazards Analysis PHA is to identify and understand the hazards associated with the process being reviewed, to understand the potential resultant hazardous events, and to prevent those events by identifying all the potential routes to those events and ensuring that adequate safeguards are in place to mitigate their risk.
We will explore two different installations and the effect on likelihood. First, consider this vessel configuration. Based on the configuration of the vessel and conversation with team members, we may conclude that the safeguards displayed below have been implemented at the facility.
If on the other hand, the vessel is configured with a solid glass tube, it would be much more susceptible to breakage due to a swinging ladder or other impact. Where unacceptably high risk rankings are assigned, recommendations should be made to reduce the danger associated with the event occurring. In order to focus attention, PHAs typically divide systems into subsystems or nodes. Once all questions for a single subsystem have been considered, the team will move on to the next subsystem.
This is repeated until all subsystems have been studied.
