Thanks to all who have shared on this topic-  as with many safety issues in research institutions, there is no “one size fits all”  SOP for this.

We do have a LOTO procedure in place- including locking out a computer keyboard which runs the MOCVD.  We include a flow chart for the decision making process.  The problem was that facilities workers were trying to circumvent the SOP buy requesting the key for the roof top, and then keeping the key so they would not have to go through the  process every time.  Or, using a scissor-jack mechanism on the outside of the building to gain access.      We ha ve both extremes -  those workers who are unduly concerned with whatever goes up a fume hood, and those who will try to get around The System.  Training, and enforcement are the key to any successful SOP.< /p>

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

 

In general, maintenance staff working on rooftop fume ho od exhaust equipment have indicated their concerns 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 have a lock-out tag-out polic y, due to the severity of the toxic gases involved.

 

Questions:

 

  1. Does anyone else have MOCVD labs, and to what exten t 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?

 

Thanks for the feedback.
