The technical package may specify a scope and frequency for periodic audits and performance criteria that could lead to changing the audit frequency. It may be a general safety and environmental performance audit or a special audit for items such as raw material storage and handling, quality control methods and documentation. The proprietary nature of a process or product or the complexity of the toll could be a reason to establish a more frequent audit schedule for certain tolls. Audits can also be conducted to follow-up on previously identified shortcomings to document that they were addressed properly. 

Similarly, hazardous raw material storage should also be minimized, with greater attention being given to just in time supply. Inventory reduction lowers inventory costs, while increasing inherent safety. In determining appropriate raw material inventories, the entire raw material supply chain must be considered. Will the supplying plant have to increase inventories to provide just in time service, and will...

Like raw material storage, the product storage must be large enough that it does not impede production. It is not very economical to shut a plant down because the...

Chemical manufacturing-from raw material storage through chemical processing to product storage. 

CSB searched over 40 data sources for incidents that met its definition of a reactive incident (Section 2.1). The data search focused on recent incidents (since 1980) where the primary cause was related to chemical reactivity however, the 1980 cutoff is not intended to diminish the important lessons learned from prior incidents. The search covered both chemical manufacturing (i.e., raw material storage, chemical processing, and product storage) and other industrial activities involving bulk chemicals, such as... 

Note The isopentane feed valve is designed to fail closed on a power failure to prevent reverse flow from the kettles to the raw material storage tanks. This is the appropriate failure position for this valve. 

The process hazards analysis for the raw material storage, catalyst preparation, catalyst storage areas was up for renewal this year. The prior PHA was not as thorough as expected by today s standards. The corporation has now established criteria for PHA leaders and has an approved list of resources. 

Conduct a thorough Process Hazards Analysis (PHA) for the following areas raw material storage, raw material feed systems, catalyst preparation, and catalyst storage. The PHA leader must he on the approved corporate list. Ensure the following scenarios are considered ...
