Fossil fuels have been the premiere resource for energy use for over a century. Whether it be powering our household car, fighter jets for the US air force, or a simple lawn mower, fossil fuels are prevalent everywhere. However, a new form of energy, Bio-alcohols, are new and considered a "sustainable" option due to the lack of fossil fuels we have left on our Earth. Bio-alcohols fall under the new class of fuel energy called Biofuels. Biofuels are a type of fuel energy that comes...

Hydrogen or deuterium gas when mixed with air or oxygen forms a highly flammable mixture over a wide range of proportions; they also form flammable mixtures with chlorine and the oxides of nitrogen, further, they will also react spontaneously with fluorine and chlorine trifluoride. Because it is impossible to guarantee that any system will be completely leak free every effort should be made to exclude all sources of ignition. The designer and the user should give careful consideration to the...
Occupational risk in kitchens whether restaurants or cafeterias. Grease fires are the major common hazards that required for extinction wet chemicals. These fires do pose hazards to workers. For the extinction of grease fires there are wet chemical systems since 1994 this according to Gagnon, Robert. These work best with vegetable oil since is lower temperature reducing probabilities of auto ignition. Also it is required for the commercial kitchens to have the extinguishment system replace the...
