Overview

The training program outlined below will assist the delegates to meet the stated training outcomes. The order in which elements of the training program are delivered may vary. To make efficient us of time and ensure effective learning there should. Wherever practicable, be an integration of the three phase of explanation, demonstration and practicable. Full use should be made of visual/audio visual aids and course handout material.

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
