PROCEDURAL TESTING

Three test strips with

Bacillus atrophaeus

Procedures chosen to

validate sanitizing effectiveness

Strips exposed in

chamber on stand to test maximum distance

PROCEDURAL TESTING

First Test

○ Exposure to UV without H2O2 vapor ○ Five minute process

Second Test

○ Chamber filled with H2O2 vapor for one second ○ Exposed to UV for five minutes ○ Compare results to first test

Third Test

○ Chamber filled with H2O2 vapor for five seconds ○ Exposed to UV for five minutes ○ Compare to first and second test

SAFETY ASSESSMENT

Fog machine gets hot during the operating

○ Add proper labels ○ Add heat shield to fog machine for safety

Tube starts ‘melting’ as the temperature gets too hot

○ Find tube material with higher melting temperature ○ Or move fogger inside chamber

There is a gap in the door seal

○ Softer sealing material ○ Tighten/eliminate spring on door latch

CONTROL SYSTEM

Arduino Uno

microcontroller

Will run code and logic

for automated process and user interface

Expect to have:

○ Indicator lights ○ Time display ○ Door lock

Conclusion

With the chamber complete,

extensive testing on procedure validity can commence

Focus can now be geared towards

addressing and complying with design requirements
