The Meeting:

indoor air qualityBefore the meeting we all met in the lounge for an excellent rib dinner, our gracious host (C&R Mechanical Company) provided. Frank Kastl, our Chapter President started out the meeting reporting on the AFE Regional meeting he attended in New Orleans. We all voted unanimously to donate all funds from cover charges to the AFE Relief fund. Don Fitchett gave a quick review of what the June meeting will have in store for us. (Don will be speaking on "The true cost of equipment downtime in a manufacturing facility".)

hazardsWe had a PowerPoint presentation set up on a lap top that Joel Leonard (AFE National Membership Chairman) had sent us. The presentation was a biography with pictures, of the World Trade Center Facility victims and families we are supporting with the donations. Don passed around his boy's toy fire hat for donations, and we collected $???.

Protecting Buildings and Their Occupants From Airborne Hazards

Arnold Appel, Director of Health Care Planning for C&R was our speaker this month. Arnold started out giving us a refresher on Bio Terrorism, adding his own insight and knowledge on the topic. He explained the importance of maintaining a positive pressure in your buildings.

 Tip: If you suspect a substance to be hazardous, do not touch or move it. Stay where you are and let help come to you.

 Arnold stressed the most important and first step in protecting your building occupants is to develop a plan. Arnold presented to us the resources to start planning with over 85 pages of handouts and internet resources too. Then he reviewed the resources with us.

Pertinent facts about airborne hazards was presented with a handout on Anthrax and Smallpox. The most notable source of information was a 22 page report by the U. S. Army Corps of Engineers. The American Hospital Association Chemical and Bio-terrorism Preparedness Checklist was of particular value to assessing where we are at and developing a plan.

Some highlights of designing your building to protect it's occupants where...

 Elevating air intakes is the best method of security. Use a fence, cameras and motion detectors when on ground level air intakes. You should isolate entry areas into the building, such as the lobby, mail room, and delivery area. A separate air unit should be used for lobby, with a slight negative pressure differential to the rest of the building. Arnold points out with today's building automation, it will take very little to come up with a a single-switch control for sheltering and purging. But these countermeasures must be planed, in place and communicated before disaster strikes.

 A reminder of what we learned meeting with the FBI:

“We have to become a hard target for terrorism, especially when it comes to the air in our buildings being contaminated by bio-terrorism.”  

We also had an open discussion about filtration techniques and decontamination with UV lights. Both methods have their inadequacies and need development. We had the good fortune of having a guest who's company has done extensive UV testing. Her insight was very helpful, and educated us on some misconceptions of UV contamination. She pointed out that UV rays must contact surface directly to be effective. This is a problem in air handling coils as they cast shadows, and UV rays will not contact back surface of coils at all. Sounds like the best method of protection and decontamination is to use a combination of all the technologies presented here tonight. :>)

In closing, some advice from our speaker, Arnold Appel ...

 Thanks you so much Arnold Appel and C&R Mechanical Company for the valuable information, food and drink.

 Thanks to those who attended, hope to see more of you in our engineering ranks at our next meeting.
