Assessment of Processing Hazard
| Hazard | Sub-Factors | Description and Reason | Weighting/Score |
|---|---|---|---|
| Processing severity | Open processing | This factor considers processing where the product is exposed for x amount of time to be a greater risk where processing is taking place, but the product remains sealed for the duration of the activity (for example, a sealed vessel wheeled into a temperature-controlled for processing and then wheeled out again). | 2 |
| Closed processing | Based on the above assessment, closed processing is a lower risk activity than an open processing activity. | 1 | |
| Nonprocessing rooms | Rooms that are not used for processing but are captive to the process area, and therefore have cleanroom status through being connected to a particular air-handling system. However, these rooms have no direct impact to the process although the risk of possible carry-through of any surface contamination from a non-process room to a process area remains. This risk is considered to be relatively small, therefore a low weighting is given. | 0 |
