The proposed changes to the 2016 edition of NFPA 13, Standard for the Installation of Sprinkler Systems, were published after the Tech Session at the 2015 NFPA Conference & Expo at the McCormick Place in Chicago. Major changes adopted included extensive revisions to the commodity classification tables, the first in two decades. For the first time in NFPA 13’s history protection schemes for Group A exposed expanded plastics stored in racks were added. Read more
Since the publication of our article on hazards of polyurethane foam fires, the investigation was extended to gather additional insights into PUF’s combustion behavior and associated combustion processes. As it is known, polyurethane foam under fire decomposes into TDI and Polyol. Specifically Polyol combustion processes are investigated in more detail, because Polyol combustion is responsible for the extremely high heat release rates observed during polyurethane foam fires.

In-rack sprinklers are used when ceiling sprinkler only protection is no longer adequate to protect the rack stored commodities. Well known disadvantages of current in-rack sprinkler designs are (1) additional costs and (2) additional risks of damage of the sprinkler heads during loading and unloading of the racks. Next generation in-rack sprinklers have been UL-tested that are expected to improve on conditions on both fronts. Read more
NFPA made available the education session presentations on their website. These free, downloadable presentation decks (in PDF format) offer an excellent opportunity for anyone looking to continue their education, or who could not attend this year’s NFPA Conference & Expo in Chicago. Audio recordings of the sessions are also available (for a nominal fee), which will help you follow along the presentation slides. Read more
There is a better in good chance that the Globally Harmonized System (GHS) will impact your business. Current fire and building codes are based on NFPA standards, which – in some cases – differ from GHS regulations. With the start of key implementation deadlines already behind us, businesses must be aware of the differences and key requirements between these two sets of regulations in order to successfully adapt to this change.

According to OSHA and the U.S. Chemical Safety Board1 over the last 35 years more than 450 accidents involving dust have killed nearly 130 workers and injured more than 800. Between the years of 2008 and 2012 alone, a total of 50 combustible dust accidents2 occurred resulting in 29 fatalities and 161 injuries. Given these grim statistics, a lot of attention and effort has been spent over recent years on highlighting the risks of combustible dust, educating the public, and developing non-disruptive, cost-effective solutions that ensure life safety in the workplace Read more
NFPA’s Fire Protection Research Foundation hosted this year’s conference on suppression and detection in Orlando, Florida. Presented were the latest research and developments in the fire protection industry that included a diverse cross-section of subjects, such as the effect of ceiling fans on smoke alarm performance, corrosion inhibition of dry and pre-action fire suppression systems, effect of obstructions on ESFR sprinklers, fire suppression in Li-Ion based electric vehicles, and many more.

ESFR protection of exposed expanded Group A plastics is currently outside the scope of NFPA 13. Attempting to fill this gap, NFPA’s Fire Protection Research Foundation set out to develop experience with these types of commodities and gather data by initiating large-scale fire tests. The goal of these tests was to evaluate the necessary level of protection when ESFR sprinklers in rack storage configurations with no in-rack sprinkler protection are applied. Read more
The risk of asphyxiation, a condition of insufficient supply of oxygen to the body, is difficult to assess because of many factors that can contribute to an oxygen deficiency. However, these factors can be measured and used to calculate the risks that can lead to the hazardous conditions that would result in potential asphyxiation. The results can be used to make decisions about the installation, storage, and use of compressed gases as prescribed by state and local fire and building codes. Read more
The International Code Council is offering free access to their I-Codes, books and Standards. Previously these documents were only available in internet (html) format. Now the International Code Council has expanded this great service of offering free access to their resources by making many of these documents available in downloadable PDF versions, that are fully searchable and have only a few limitations, such that there is no print capability.
