12/1/2008 - Peer reviewed journal articlesThis paper discusses methods of preventing CO migration, lessening migrated CO, and detecting CO in underground enclosed spaces and may help reduce exposure of area residents to CO and help prevent unnecessary regulations and blasting limitations.
-
1/1/2006 - Conference papersToxic fumes generated by explosives have been a concern for blasters, explosive manufacturers, and mining companies. In this study, 10 lb. charges of confined blasting agent were detonated in a closed chamber, and then detonation gases were analyzed.
-
2/1/2005 - Conference papersDescribes a small-scale field study to identify key factors that may contribute to the migration of CO through the ground.
-
4/12/2020 - Research projectsA project to demonstrate the suitability and efficiency of monitoring and control solutions which will help to lower the respirable dust exposure of metal/nonmetal miners.
-
11/1/2007 - Peer reviewed journal articlesThis paper describes a study in which a field colorimetric method for extracting and measuring manganese in welding fume was developed.
-
1/1/2007 - Conference papersThis paper reviews the potential hazards from toxic fumes produced by detonating explosives in surface mining and construction operations. Techniques to protect workers and the public from the hazards of explosive-related toxic fumes are discussed.

2/1/2003 - Conference papersReport on NIOSH studies using a 12-foot diameter sphere to identify key factors that may enhance the levels of CO associated with the detonation of several commercial trenching explosives.
-
2/1/2002 - Conference papersReport on a NIOSH study to identify factors that may contribute to nitrogen oxides (NOx) production associated with non-ideal detonation of blasting agents.
-
5/1/2001 - Technology NewsNIOSH tech news report on an incident where CO generated from blasting at a strip mine migrated through the ground into a nearby home, poisoning the occupants.
