1. WHAT IS FIRE GAS MAPPING?
  • Fire-gas mapping is a solution that assists in the evaluation of flame and gas risks within a process facility and in the reduction of these risks towards an acceptable risk profile.
  • This includes placing of detectors in appropriate locations to achieve best possible detection coverage.
  • It is designed and installed to protect large and complex areas filled with process equipment from risks of combustible or toxic gas leaks, explosions and flames.
  • It offers high likelihood of detecting the presence of any flame and gas hazards within monitored process areas.
  1. HOW DOES IT WORK?
  • It uses a number of assumptions in order to make it possible to assess sites.
  • It is assumed that all gas detectors are either point or open path gas detectors, and that gas is detected if the accumulation envelopes a detector or intersects the track of an open path detector.
  • Each area assessed is represented as a regular orthogonal volume specified in terms of its length, width and height (or Cartesian coordinates, X, Y and Z dimensions).
  • The results of the assessment are available both as a numerical summary and as a series of horizontal ‘slices’ through the volume in readable and measurable form.
  1. WHAT ARE THE BENEFITS?
  • Increase plant safety by improving the likelihood of detecting flame and gas hazards. For new installations, mapping can help improve the design of new fire & gas systems to mitigate risks from accidental gas releases. For existing installations, mapping provides a method for assessing the risk reduction performance of existing fire & gas detector systems and recommends ways to improve coverage.
  • Optimize resource allocations and minimize system costs. Through mapping, the appropriate types and quantities of flame and gas detectors that provide the desired detection coverage can be objectively determined. Mapping also equips the engineer with the means to measure detection improvements when small incremental design changes are made. Mapping can therefore help minimize overall system costs.
  • Improve design accuracy and engineering efficiency. With mapping, deciding detector layouts becomes a lot easier because mapping provides a methodical and systematic approach for determining the areas with the highest likelihood of flame and gas risks. Understanding the locations and likelihood of risks will help remove guesswork and inefficiencies from engineering.
