![]() Environmental Protection Agency's Title III Consolidated List of CAUTION: When in contact with refrigerated/cryogenic liquids, many materials become brittle and are likely to break without warning. Prevent spreading of vapors through sewers, ventilation systems and confined areas. Use a high-expansion foam if available to reduce vapors. CAUTION: For LNG - Liquefied natural gas ( UN1972), DO NOT apply water, regular or alcohol-resistant foam directly on spill. Do not direct water at spill or source of leak. Avoid allowing water runoff to contact spilled material. Use water spray to reduce vapors or divert vapor cloud drift. If possible, turn leaking containers so that gas escapes rather than liquid. Do not touch or walk through spilled material. All equipment used when handling the product must be grounded. (ERG, 2020)ĮLIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. For massive fire, use unmanned master stream devices or monitor nozzles if this is impossible, withdraw from area and let fire burn. ALWAYS stay away from tanks engulfed in fire. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. Do not direct water at source of leak or safety devices icing may occur. Cool containers with flooding quantities of water until well after fire is out. Use dry chemical or high-expansion foam.įIRE INVOLVING TANKS: Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles. CAUTION: For LNG - Liquefied natural gas ( UN1972) pool fires, DO NOT USE water. ![]() If it can be done safely, move undamaged containers away from the area around the fire. Use an alternate method of detection (thermal camera, broom handle, etc.). CAUTION: Hydrogen ( UN1049), Deuterium ( UN1957), Hydrogen, refrigerated liquid ( UN1966) and Hydrogen and Methane mixture, compressed ( UN2034) will burn with an invisible flame. Anthony Ranchou-Peyruse is a member of IPREM (CNRS/UPPA).Īs part of his research activity, he is interested in understanding the functioning of deep continental microbial ecosystems and has been collaborating for more than 10 years with industrialists exploiting geological resources.Excerpt from ERG Guide 115 :ĭO NOT EXTINGUISH A LEAKING GAS FIRE UNLESS LEAK CAN BE STOPPED. to provide technical guidance for its exploration and production.ĭr.to new tools and methodologies to reduce the risks associated with geological storage.to a better understanding of the processes controlling H 2 migration and retention in geological formations.Although quantities remain to be determined, H 2 is also produced as a geological resource from natural emissions. It can be transported and stored in large amounts into underground natural reservoirs, such as aquifers. Hydrogen (H 2) is a very promising resource but it is mainly obtained by hydrocarbon reforming, though it can also be generated by water electrolysis using the excess of energy produced by renewables. This project, in line with the partner activities, will focus on H 2 mobility and bio-chemical reactivity in natural porous media, from deep environments to surface. The ORHYON industrial chair, funded by the ANR and Engie, is based on the complementary strengths of Engie, UPPA and IFPEN.
