Hazard analysis personnel

The book does not focus on occupational safety and health issues, although improved process safety can benefit these areas. Detailed engineering designs are outside the scope of this work. This book intends to identify issues and concerns in batch reaction systems and provide potential solutions to address these concerns. This should be of value to process design engineers, operators, maintenance personnel, as well as members of process hazards analysis teams. While this book offers potential solutions to specific issues/concerns, ultimately the user needs to make the case for the solutions that provide a balance between risk... 

The what if/checklist is a broadly based hazard assessment technique that combines the creative thinking of a selected team of specialists with the methodical focus of a prepared checklist. The result is a comprehensive hazard analysis that is useful in training operating personnel on the hazards of the particular operation. 

The employer establishes a system to promptly address the team s results, timely resolve recommendations, schedule completion, and communicate the activities to affected personnel, livery five years after the completion of the initial process hazard analysis, it is equivalently updated and revalidated. Employers retain the required process hazards analyses for the life of the nmei-v -.. 

To develop a safe design, it is necessary to first design and specify all equipment and systems in accordance with applicable codes and standards. Once the system is designed, a process safety shutdown system is specified to assure that potential hazards that can be detected by measuring process upsets are detected, and that appropriate safety actions (normally an automatic shutdown) are initiated. A hazards analysis is then normally undertaken to identify and mitigate potential hazards that could lead to fire, explosion, pollution, or injury to personnel and that cannot be detected as process upsets. Finally, a system of safety management is implemented to assure the system is operated and maintained in a safe manner by personnel who have received adequate training. 

While RP14C provides guidance on the need for process safety devices, it is desirable to perform a complete hazards analysis of tlie facility to identify hazards that are not necessarily detected or contained by process sLifety devices and that could lead to loss of containment of hydrocarbons or otherwise lead to fire, explosion, pollution, or injury to personnel. The industry consensus standard, American Petroleum Institute Recommended Practice 14J, Design and Hazards Analysis for Offshore Facilities (RP14J), provides guidance as to the use of various hazards analysis techniques. 

A designer, as part of his facility design analysis, should perform a hazards analysis or risk assessment of the various processes which will be conducted within the facility in order to determine what potential thermal dangers or threats exist to personnel and equipment. A hazards analysis or risk assessment will provide for the identification of potential hazards and of the necessary corrective actions/measures to prevent or control the hazard. Early in the design of a facility, the processes and equipment may be conceptual and at this stage, a preliminary hazards analysis can be performed. It is early in the design that a preliminary hazards analysis can be most helpful because its... 

Fire hazard analysis (FHA) is the process to determine the size, severity, and duration of a scenario and its impact on personnel, equipment, operations, and the environment. Chapter 5 provided details of performing an FHA. The following paragraphs provide an overview of the FHA process. For example, one scenario could be a seal failure where the material being released is ignited and afire results. In assessing consequences, several questions must be considered ...

Good communications are critical. If there are special situations, such as hot tapping, or unique conditions in which hazardous materials cannot be easily removed (such as the accumulation of solids that cannot be dissolved away), or if the clearing procedures cannot be followed or do not exist, then key professional personnel must perform a hazards analysis and re-evaluate the situation. Personnel must not continue scheduled maintenance until safety can be guaranteed. [30]... 

As with most of a company s information where proprietary, trade secrets, or a facilities security may be involved, process hazard analysis reports may be considered confidential information. Release outside the company should be discussed with the legal staff or by the contractor agreements made with outside personnel participating in the study. A suitable distinction should be applied to the cover of any review produced documents whenever the confidentiality requirement is required. 

A detailed safety assessment including personnel hazard analysis (PHA), hazardous operations (HAZOP) and failure mode and effects analysis (FMEA) has been performed. The assessment will be expanded to ensure that the system is compliant with all applicable building, fire and electrical codes. 

What are the qualifications of personnel performing chemical hazard analysis Are "hands-on" employees involved in all chemical hazard analyses conducted by SMEs Do environment, safety and health (ES H) professionals conduct walk-downs of feciUties in which chemicals are to be used... 

Lots of recommendations for changes could be generated from this part of the analysis, such as providing rigorous procedures for hazard analysis when a hazardous condition is detected and training and assigning personnel to do such an analysis. Better communication channels are also indicated, particularly problem reporting channels. 

Setting up a safety information system for a single project or product may be easier. The effort starts in the development process and then is passed on for use in operations. The information accumulated during the safety-driven design process provides the baseline for operations, as described in chapter 12. For example, the identification of critical items in the hazard analysis can be used as input to the maintenance process for prioritization. Another example is the use of the assumptions underlying the hazard analysis to guide the audit and performance assessment process. But first the information needs to be recorded and easily located and used by operations personnel.
