introduction
Introduction
  • High risk
  • Need to reduce risks

We will cover two areas:

  • Fire
  • Design of the blending system
fire triangle
Fire Triangle
  • To create fire need 3 elements:

OXYGEN

FUEL HEAT

oxygen
Oxygen
  • Supports combustion
  • Not fuel
  • Removal prevents fire
  • 100% oxygen for blending
  • Other precautions necessary
  • Safety data sheets
slide5
Fuel
  • Identify potential fuels
  • Hydrocarbons
  • Easily combust at low temperatures
  • Compressors
  • Contaminants
  • Use compatible components
    • Higher heat tolerance
    • Reduce risk
heat ignition
Heat (ignition)
  • Control heat production
  • Friction of compressing gas
  • Opening valves
  • Adiabatic compression
  • Avoid excessive heat generation
fire prevention
Fire Prevention
  • Cannot remove oxygen!
  • Cannot remove 100% of fuel
  • Can control heat production
    • Open fill cylinder first

FILL SLOWLY

5 –7 bar / minute

design of system
Design of System
  • Seek advice
  • Decide blending method
  • Identify dangers
  • List required equipment
  • Manufacturers recommendations
  • Choose suitable components
  • Siting
  • Inspection / Cleaning
use of the system
Use of the System
  • Trained
  • Familiar
  • Keep up to date
  • Attitude
  • Technique
  • NOT A SOCIAL OCCASION
cleaning the system
Cleaning the system
  • > 40 % in oxygen service
  • Contaminant free
  • Compatible parts
    • Metals: copper based allo
    • Non-metals: Viton, Teflon or Kel-F
    • Lubricants: non-petroleum
  • Manufacturer’s recommendations
summary
Summary
  • We covered :
    • Fire
    • Design of the blending system
