31 Ammonia Treatment 15 th Annual OSC Readiness Training Program 30

32 Ammonia & Chlorine Treatment 8NH3 + 3Cl2 6NH4Cl + N2 (when ammonia is in excess) 2NH3 + 3Cl2 6HCl + N2 NH3 + 3Cl2 NCl3 + 3HCl (when chlorine is in excess) Nitrogen trichloride (NCl3) is a dangerous explosive, being sensitive to light, heat, and organic compounds. Nitrogen trichloride can form in small amounts in public water supplies and in swimming pools between disinfecting chlorine and urea in urine from bathers(twa of 0.5 mg/m 3 ). 15 th Annual OSC Readiness Training Program 31

33 Ammonia Treatment NH 3 + HCl or Cl 2 NH 4 Cl 15 th Annual OSC Readiness Training Program

34 Cylinder Content Treatment Acetylene Flammable range: 2.5 to 81% Although acetylene will not undergo combustion at concentrations above the UFL, it can undergo an explosive decomposition reaction, even at concentrations of 100%. This is dependent on pressure container size, shape and presence of an ignition source. Acetone or Dimethyl-formamide (DMF). To minimize the withdrawal of the solvent, acetylene should be withdrawn at a rate of 1/7 of the cylinder s rated capacity when full. Cylinder capacity divided by 7. Above 15 psi acetylene becomes unstable 15 th Annual OSC Readiness Training Program 33
