Assessment of Drain Hazard
| Hazard | Sub-Factors | Description and Reason | Weighting/Score |
|---|---|---|---|
| Drain probability | Present | The presence of a drain in a cleanroom is a potential risk due to the likelihood of micro-organisms being present and of biofilm communities to grow. Drains should be sanitized routinely, which should minimize the contamination risk (and verified by swab monitoring). However, the presence of a drain will always be a relatively higher risk when compared to a room that does not have a drain. | 1 |
| Not present | Based on the above assessment, clean areas without a drain are a lower risk than clean areas that have a drain. Therefore no score is applicable. | 0 |
