11/1/2006 - Peer reviewed journal articlesNIOSH researchers studied laser safety in potentially flammable environments. Researchers measured threshold igniting powers as a function of beam diameter for butane and propane-air mixtures by laser-heating targets placed on optical fiber tips.
-
9/1/2006 - Peer reviewed journal articlesResearchers conducted experiments to estimate the mean and standard deviation of laser powers needed to ignite 6% methane-air atmospheres using single-mode optical fiber tips covered by two types of iron oxide mixed with a ceramic adhesive.

8/1/2003 - Peer reviewed journal articlesLaser-based instruments are used in areas where coal dust ignition presents a safety hazard. This NIOSH study determines when an optical beam may be considered a potential ignition source in underground coal mines or coal storage facilities.
-
5/1/2000 - Peer reviewed journal articlesOptical technologies have progressed rapidly in the past 15 years. NIOSH is conducting a study to help provide a scientific basis for developing appropriate safety guidelines for optical equipment in underground coal mines.

12/1/2019 - Peer reviewed journal articlesThis paper discusses the implications of floor dust erosion on rock dusting and sampling procedures for explosion hazard assessment.
-
11/1/2014 - Peer reviewed journal articlesA study that continues research into the potential for lithium and lithium-ion battery thermal runaway from an internal short circuit in equipment for use in underground coal mines.
-
1/1/2012 - Peer reviewed journal articlesThis paper describes tests conducted to evaluate the effectiveness of the Barricade II Fire Blocking Gel.
-
1/1/2011 - Peer reviewed journal articlesThirteen coals of different rank were tested for ignition propensity in a 20-L explosion chamber simulating oxyfuel combustion gas conditions. The effects of coal type, coal concentration, O2 in CO2 atmospheres, and particle size were investigated.
-
8/1/2009 - Peer reviewed journal articlesNIOSH conducted a statistical study of available data regarding frictional ignitions in the United States from 1983 to 2005 to determine and define conditions controlling their occurrence.
-
7/1/2006 - Peer reviewed journal articlesA study of the ignition of non-fire-resistant hydraulic fluid sprays was conducted by NIOSH. Both an open flame and a hot steel surface were used as the external heat sources.
