Where discharge from the system discharge devices would create a hazardous condition or conflict with local requirements, an approved alternate method to achieve full flow conditions shall be permitted.
The dry testing method has many benefits:
- Testing is safer and less expensive
- The testing can be performed without interrupting production
- The preparation for dry deluge testing is less than wet tests
- Any leaking flow pipes are easier to identify
- Residual water from former tests will be blown out of the deluge system
- The process equipment is protected from any water contact during testing maintaining plant integrity
- Reduced internal corrosion in flow pipes, leading to less solids in the system and thus, resulting in fewer blockages
- No new organisms like shells can grow in flow pipes, reducing blockages
