Introduction: In our first Volume of the Forensic Exchanger, we discussed some of the all too many reasons why HVAC systems fail. If you missed that edition and are interested in that topic e-mail us and we will gladly send it to you. We will follow up with more discussion of that important topic in later editions
Facilities which utilize hazardous liquids and gases represent a significant potential liability to the owner, operator, and general public in terms of personnel safety and preservation of assets. It is obvious that a catastrophic incident or loss of property or personnel is to be avoided at all costs. This book was conceived to give the reader a guide to understanding the requirements of the various codes and regulations that apply to the design, construction, and operation of facilities utilizing hazardous materials in their processes.

Schools, campuses, houses of worship, recreational sites, transportation hubs, retail facilities, those thoughts ring out day after day. Replay in your mind’s eye the horrific images of Columbine High School, Virginia Tech, Northern Illinois University (Valentine’s Day), Aurora Colorado movie theater, Sandy Hook Elementary School
At schools, campuses, sporting events, and retail facilities, those thoughts ring out day after day. We have watched with horror the increasingly more frequent news of violence at establishments we once thought "safe" from wanton violence. One has to just scan the news to see that no place is immune from any type of random act that injures or kills innocent civilians, be it a movie theater, retail mall, sporting event, school, or church. In this column, let's take a look at a few basic elements.
Emergency managers and officials have seen a tremendous increase in the planning responsibilities placed on their shoulders over the last decade. Crisis Management and Emergency Planning: Preparing for Today's Challenges supplies time-tested insights to help communities and organizations become better prepared to cope with natural and manmade disasters and their impacts on the areas they serve.
This book offers preparedness and mitigation recommendations for advanced emergency planning. Because disasters are so unpredictable, advance planning is needed to effectively respond to and mitigate against the potential effects of such events. More than a dozen contributors offer their professional expertise on a wide variety of topics.
This book provides a clear and up-to-date understanding of how an EOC should operate within the guidance of various federal and national programs. It discusses the processes and systems that must be considered in emergency planning and preparedness efforts, and provides time-tested tips for those developing and revising emergency preparedness plans.

We have observed a trend in personal injuries and the litigation-support business regarding elevator noncontact, infrared door detectors, aka "door detectors." These devices were introduced in the early 1990s and instantly recognized by owners and contractors as valuable and important upgrades to passenger elevators. These passenger-safety door protection devices project a 2D array of infrared sensor beams across the full width and height of the elevator door entrance threshold and pathway.
The demise of the hydraulic elevator was forecast with the introduction of the MRL traction elevator about 20 years ago; In spite of this new design conveyance, the hydraulic elevator is again beginning to thrive in the US market. The threat of replacement by the MRL traction elevator is now waning. Hydraulic elevators are still viewed by many within the industry as the best selection for many buildings, in most applications for travel of 50 feet and less, the hydraulic elevator will perform as well as a traction elevator. However, speed and travel is a limiting factor.
