In the new issue of NFPA Journal®, President Jim Shannon said the Association will focus on the leading causes of home fires, including cooking. "We also need to continue to push hard for home fire sprinklers. That's still a large priority for NFPA, and we plan to work very aggressively in 2014 on our residential sprinkler initiative," he said.

Almost every consulting engineer works with codes and standards on a daily basis, but do you know the difference between a code and a standard?
According to the National Institute of Standards and Technology (NIST) Circular No. A-119, Revised, a standard is "[t]he definition of terms; classification of components; delineation of procedures; specification of dimensions, materials, performance, designs, or operations; measurement of quality and quantity in describing materials, processes, products, systems, services, or practices; test methods and sampling procedures; or descriptions of fit and measurements of size or strength." In plain English, a standard consists of technical definitions, procedures, and/or guidelines that specify minimum requirements or instructions for manufacturers, installers, and users of equipment. This can be done by specifying either the methods or the results; the latter is known as "performance specifying." Most importantly, a standard provides standardization or agreement within the industry, which translates to a common reference among engineers, manufacturers, and bidders.
Since the 1989 Montreal Protocol and its successor agreements, the world of refrigerants has been marked by change. In the search for more environmentally-preferable refrigerants, technology has moved from chlorofluorocarbons to a host of alternative substances. Many of these substances are serving as interim measures, until the phase-out of ozone-depleting and global-warming refrigerants meets the targets set by the U.S. Clean Air Act. The journey toward compliance has caused the HVAC equipment and appliance industries to revisit the potential use of substances that have good environmental and thermodynamic properties as refrigerants, but which are also, unfortunately, flammable.
This recall involves Cree LED T8 lamps used indoors to replace traditional two pin T8 fluorescent tubes. The white lamps have a cylindrical shape and measure 48 inches long. The affected units are marked as “BT848 Series Lamp” with the product part number on the lamp itself or printed on a white label affixed to the lamp. A four digit date code is printed on the lamp under a statement that reads “Compatible with Instant Start, Rapid Start and Dimmable Electronic Ballasts.”

CCAI Member John DeHaan joined up with Instructors Chris Connealy and Kelly Kistner in presenting “Arson Convictions: Reviewing the Science – The Texas Experience”. Jamie and Cameron Novak were on hand to set things on fire in "Burn to Learn". Rounding out the week was Mike Bryant teaching "Investigative Interviewing for Fire Investigations. Many other instructors joined in the training and in all, four separate tracks of education were presented throughout the weeklong conference.
