Training Content

Element 1 – Testing in Confined Space

Give and explanation of:

• Confined space criteria
• Limited openings for entry and exit
• Unfavorable natural ventilation
• Not designed for continues worker occupancy
• The type of production operation being tested for flammable and toxic gases
• The potential cumulative hazards of operations within an oxygen deficient, toxic or flammable environment
• Carrying out a suitable and sufficient risk assessment before testing activities and confined space entry
• Using safe systems of work including
• Appointment of a supervisor

Entry permits

Ventilation

Testing and continuous monitoring of the air

using observers to raise the alarm and initiate emergency response

Element 2 – Relevant Legislative Controls

Give and explanation of:

• The implications of organizational and statutory requirements with respect to gas testing – to include HASAWA,Confined space regulations,COSHH and the relevant codes of practice and PFEER
• The fact that the owner is responsible to make the confined space safe for entry
• How to interpret operational requirements – to include policies, procedures, instructions, codes of practice nd standards
• How to select, use and care for PPE for different toxic and flammable gases through risk assessment
• Consideration of appropriate levels of respiratory protective equipment
• How to work both with and within the permit to work system

Element 3 – Atmosphere measuring and monitoring equipment

Give and explanation of:

• How to access and interpret the relevant operational instructions
• The operating principles of atmosphere monitoring and measuring equipment and frequently observed failure modes
• The strengths and weakness of the various types of atmospheric flammable and toxic gas detection equipment – to include transportable, portable and personal monitors
• How to correctly select between aspirating and non- aspirating detectors to obtain a representative sample of the atmosphere being tested
• Equipment required in inert atmosphere
• Gas detector pre – start checks
• Calibrating the instruments used in atmospheric testing

Element 4 – Gas testing in confined spaces

Give and explanation of:

• The hazards and properties of flammable and toxic gases including oxygen deficiency and enrichment, nitrogen and specialist materials appropriate to the location
• The behavior of different gases – to include heavier than air & lighter than air behavior and “neutral buoyancy” effect.
• The range and frequency of test
• Acceptable levels of flammable and toxic gases and the correct amount of oxygen
• The implication of WEL for toxic gases and LEL for flammable gases
• How to setup the relevant detector for each gas testing application, its potential failure modes and confirming its correct functioning
• Performing gas testes in sequence: a. oxygen deficient or enriched atmospheres – ensure that proper oxygen levels are present b. flammable atmospheres – ensure that combustible gases are not present c. toxic atmospheres – ensure that toxic gases are below the exposure limit
• How to correctly select between aspirating and non-aspirating detectors to obtain a representative sample of the atmosphere being tested
• How to obtain a representative atmosphere sample from a range of confined spaces
• Taking samples at the top, middle and bottom to locate varying concentrations of gases and vapors
• Sampling confined spaces at a distance from the opening because air intrusion near the entrance can give a false sense of adequate oxygen present
• Testing flammable gases in inert atmosphere
• Monitoring and retesting after the initial entry 4.14 – where to site ongoing monitoring equipment for vessel entry

Element 5 – Interpreting and documenting the results

Give and explanation of:

• How to interpret the results, to include both normal and abnormal
• how to document the results and advise relevant personnel
