Subject: [DCHAS-L] Roof top exhaust fan maintenance Policy


In general, maintenance staff working on rooftop fume hood exhaust equipment have indicated their concern s about being on a roof, and possibly being exposed to whatever is being vented. 


In a more specific laboratory situation, involving MOCVD (metal organic chemical vapor deposition), we ha ve a lock-out tag-out policy, due to the severity of the toxic gases involved.




1.  ;     Does anyone else have MOCVD labs, and to what ext ent are controls in place for protection of workers on roof tops?

2.  ;     Does anyone else employ a LOTO policy?   

3.  ;     Are roof tops key-accessible only?< /p>


Thanks for the feedback.
