Assessment of Explosion Hazards of Unstable Substances
Means are required to assess hazards by small-scale experiments. Those commonly used are based upon the science of conventional explosives with important modifications. Several types of explosion may occur: a detonation, propagating supersonically; a deflagration, propagating subsonically; so-called homogeneous explosion in which reaction occurs almost simultaneously throughout the mass. The ev...
متن کاملFire and explosion hazards in operating theatres.
A high degree of safety from fires and explosions exists in operating theatres in the U.K. and this is reflected in the extremely low number of fatal and non-fatal accidents which occur. This has been achieved by safety precautions which in some respects have been over-careful and overexpensive. Antistatic precautions applied to the breathing circuit seem to have been the crucial factor in achi...
متن کاملDeliquescence, Efflorescence, and Water Activity in Ammonium Nitrate and Mixed Ammonium Nitrate/Succinic Acid Microparticles
We have investigated the thermodynamics and kinetics of ammonium nitrate/water and mixed ammonium nitrate/succinic acid/water microparticles. The water activity of ammonium nitrate microparticles is determined as a function of composition down to 12% relative humidity by accounting for the rapid evaporation of ammonia and nitric acid. Both the observed deliquescence and water activities for amm...
متن کامل[Quaternary ammonium compounds--new occupational hazards].
Quaternary ammonium compounds (QACs, quats) belong to organic ionic chemical agents which display unique properties of both surfactants and disinfectants. Their wide distribution in the work environment and also in private households brings about new occupational hazards. This paper reviews reports about the health effects of QACs. QACs could play a role of sensitizers and irritants to the skin...
متن کاملBis(pyridin-2-ylmethyl)ammonium nitrate
In the title compound, C12H14N3 (+)·NO3 (-), the mononitrate of protonated bis-(pyridin-2-ylmeth-yl)amine, the least-squares planes defined by the non-H atoms of the two aromatic moieties inter-sect at an angle of 7.91 (6)°. In the crystal, N-H⋯N, N-H⋯O and C-H⋯N hydrogen bonds, as well as C-H⋯O contacts, connect the entities into a three-dimensional network. The shortest centroid-centroid dist...
