Revalidating process hazard analyses (eBook, ) [globicate.com]
In specific cases, vulnerable groups of the population, e. Addressing your PHA revalidation and update procedure, we noted the following: The use of a preliminary hazard analysis will assist an employer in determining which process should be of the highest priority for hazard analysis resulting in the greatest improvement in safety at the facility occurring first.
The monitoring procedures must be able to detect loss of control at the CCP. Maintain a working inventory of liquid RM which is supplied by tank rail cars from outside suppliers. During hazard identification, evaluation, and subsequent operations in designing and applying HACCP systems, consideration must be given to the impact of raw materials, ingredients, food manufacturing practices, role of manufacturing processes to control hazards, likely end-use of the product, categories of consumers of concern, and epidemiological evidence relative to food safety.
Even though OSHA does not specify other requirements for this standard, Considering the complexity of today's chemical processes, the challenges involved in facilitating a PHA study, and the potential liabilities from an incident, your best option for completing PHAs may be to seek the assistance of expert specialists.
It is good engineering practice. Initiating cause frequency Loss event impact Safeguards effectiveness If the scenario risk is found to be too high, safeguards are considered inadequate Risk based on: The operator noticed and responded to the alarm right away, stopping the unloading operation.
What is the consequence? The HACCP application should be reviewed and necessary changes made when any modification is made in the product, process, or any step. Data derived from monitoring must be evaluated by a designated person with knowledge and authority to carry out corrective actions when indicated.
Performance of revalidation PHAs. Most monitoring procedures for CCPs will need to be done rapidly because they relate to on-line processes and there will not be time for lengthy analytical testing.

The pressure reducing valve vent becomes stuck in the open position? Protecting lives, assets, and the environment depends on the quality of PHA studies and studies must be performed properly. A chlorine main cylinder valve develops a leak while the cylinder is in operation?
The only requirements OSHA specifies in the subject standard is that the PHA update and revalidation be conducted at least every five years by a team which meets the requirements of In conducting the hazard analysis, wherever possible the following should be included: Studies are performed at the design stage to improve safety before a process is built.
OSHA does not intend that the requirement to update and revalidate PHAs at least every five years mean that an employer must conduct all new and complete PHAs on processes which have received initial PHAs as required by the standard. Actions taken must also include proper disposition of the affected product.
Where possible, process adjustments should be made when monitoring results indicate a trend towards loss of control at a CCP.

A PHA, or evaluation, is one of the most important elements of the process safety management program. The checklist may miss the most recent changes and consequently they would not be evaluated. If monitoring is not continuous, then the amount or frequency of monitoring must be sufficient to guarantee the CCP is in control.
Other approaches may be used. Performance of design-stage PHAs. Is it a new process or one that has been changed frequently by the inclusion of innovation features? All records and documents associated with monitoring CCPs must be signed by the person s doing the monitoring and by a responsible reviewing official s of the company.
Wherever a process parameter changes At end of line vessel interface Line may include pump, valves, filter, etc. Companies that handle or process highly hazardous chemicals have a responsibility to protect employees, the public and the environment from exposure to accidental releases.
Revalidating Process Hazard Analyses
They help companies identify hazard scenarios for a process that could adversely affect people, property, or the environment. The employer must perform an initial process hazard analysis hazard evaluation on all processes covered by the PSM standard. What is the initiating cause? The financial cost of catastrophic accidents is exceptionally high and PHA can be considered an inexpensive form of insurance.
Commonly a period of 5 years is used.
