    Course Objective

    • The purpose of this program is to identify the causes of hazardous atmospheres and
    • reasons to carry out the gas testing.
    • Learners can identify the procedures and processes associated with gas testing.
    • Learners recognize the properties and characteristics of flammable, explosive, and
    • toxic gases.
    • The expected outcome of the program is to know all the applications and types of
    • portable gas detectors and operation.
    • Explain the roles and responsibilities of the personnel involved (Gas Tester).
    The learner can:
    • Explain the purpose of Gas Testing
    • Explain the hazards associated with flammable and toxic gases and oxygen-deficient environments.
    • Explain various aspects of flammable Gases.
    • Explain the roles and responsibilities of the personnel involved (Gas Tester).
    • Explain the meaning of Upper and Low explosive limits (LEL & UEL).
    • Explain the behavior of different flammable and toxic gases including H2S, SO2, CO, and CO2, and their acceptable levels
    • Explain hazards of operation within an Oxygen-deficient & enriched environment.
    • Be able to identify different measurement units for atmospheric contamination
    • Explain the importance of selecting the correct equipment for the environmental conditions
    • Explain why a pre-use check should be carried out before each gas test
    • Explain how to correctly calibrate atmosphere monitoring and measuring equipment
