INTRODUCTION and COURSE DESCRIPTION The international oil and gas industry recognises that a major objective is to prevent incidents occurring, and if they do occur, to control them and minimise their effect. It is important therefore to set common standards of training and to ensure they are maintained. The specific purpose of this document is to set out the basic training, validation and certification requirements for Authorised Gas Testers (Levels 1, 2 & 3) conducted at OPITO approved training centres. The gas tester role is critical to ensure safe working conditions in permit controlled confined space or for hot work. Even sentries should be trained in gas testing skills as they play the lead in maintaining a safe working environment. It will be for the duty holder or nominated representative to decide which personnel will undergo this training according to the requirements of the employing organisation. Operating companies and employers should also recognise that site specific training is integral to the training of a gas tester. Where there is a need to have competence formally confirmed this will be done at the workplace through a company’s competence management system against the National Occupational Standard for The Testing for Oxygen, Toxic and Flammable Gases , which is included in Section E . An OPITO certificate is not awarded for an assessment of competence.
These standards have been developed using the UK legislative framework. Where this regime does not apply, training providers may substitute national requirements and demonstrate to OPITO their equivalence. Where no suitable equivalence exists the training provider should use the UK framework as an exemplar.

FOR THE PURPOSE OF THIS STANDARD Validate means to look at a “snapshot” of a delegate’s knowledge or performance at a particular point in time; for example, watching the delegate demonstrating initial training activities or the fact that he/she has passed a written examination. Assess, and its associated nouns assessment and assessor, refer to the more in-depth analysis of a candidate’s performance during a formal competence assessment. Occasionally, qualified assessors are required to validate that the training outcomes have been achieved by delegates in a training course; individual OPITO standards specifically outline this requirement in Section C.1, if applicable.
SECTION A
INITIAL TRAINING PROGRAMME
Delegates attending this training programme will be given either: (a) (b)
a series of presentations or a computer based training programme (see Appendix 1)
Irrespective of the method used, the programme will explain to the delegates what they are expected to know and do when testing for oxygen and toxic and flammable gases. The role of Authorised Gas Tester has three levels. Each level requires a different degree of knowledge as listed in A.4 Training Programme. The various levels do not represent a progression, but are unique training courses in their own right. Because there is some overlap it is up to the operators and training providers to decide how best to deliver the training levels, i.e. as three separate programmes or amalgamated into one or two single programmes.

A.1
Target Groups
These programmes are designed to meet the initial onshore training and validation requirements for personnel preparing to work as Authorised Gas Testers for a variety of products and work environments. AGT Level 1 is required for those involved with performing a test for oxygen, flammable and toxic gases up to and including working in confined spaces. NOTE: Persons undertaking Safety Watch duties at the entrance to a confined space shall be an AGT Level 1 Gas Tester. AGT Level 2 is required for those involved with testing for flammable gas in preparation for hot work. AGT Level 3 is required for those who provide safety watch duties by the ongoing monitoring of a hot work site.
A.2
Delegate Prior Achievement
There are no delegate pre-requisites for attendance on each of these courses.
A.3
Physical & Stressful Demands of the Courses
All personnel who participate in gas testing training should be medically fit and capable of participating fully. The responsibility for the individual completing the course, without any adverse effects to their present state of health, lies with the delegate and/or the company sponsoring the delegate. Where doubt exists regarding the medical fitness of any delegate the training establishment should seek the advice of a medical officer.

A.4
Performance Validation
Delegates attending these training and validation programmes will be given a series of explanations and demonstrations which will identify what they are expected to know and do. Validation of the delegates' performance will be against the stated training outcomes in A.5 Training Outcomes regardless of the delivery methodology used. A multiple choice written test with a minimum of 20 questions and a pass mark of 80%, should be used to gauge the delegates’ understanding of the topics. Delegates successfully completing the course validation will be judged to have been given the underpinning knowledge for Authorised Gas Tester Level 1, 2 or 3 to proceed to the workplace for site specific assessment under direct supervision of a competent person’. If required, further time and opportunity for coaching will be given to delegates to enable them to reach the standard leading to the award of a certificate. However, the time available for this during a programme is limited and it should be recognised there may be occasions where other arrangements need to be made.
A.5

SECTION E E.1
OPITO APPROVED COMPETENCE STATEMENTS
Development of Competence Statements
To develop a training course, an assessment of workplace competence is required. In other words, what does an employee have to know and do if he/she is an Authorised Gas Tester? The competence statements from the National Occupational Standard for The Testing for Oxygen, Toxic and Flammable Gases are included in this section. Using a competence-based approach the following were identified and developed for this role: (a)
What personnel are expected to do
(b)
The underpinning knowledge and skills they would require to enable them to do what was expected
(c)
How they could demonstrate what was expected of them
(d)
How their performance would be assessed
Using the identified knowledge and skills, the content of a training programme was developed and is outlined in Section A of this standard.
E.2
Competence Outcomes
Three levels of persons are involved with testing for oxygen, flammable and toxic gases. AGT Level 1 is required for those involved with performing a test for oxygen, flammable and toxic gases up to and including working in confined spaces. Personnel undertaking this role will be assessed against Units 1, 2 & 3 (which are outlined in E.3 Competence Units). NOTE: Persons undertaking Standby/Safety Watch duties at the entrance to a confined space shall be an AGT Level 1 Gas Tester. AGT Level 2 is required for those involved with testing for flammable gas in preparation for hot work. Personnel undertaking this role will be assessed against Units 2 & 3. AGT Level 3 is required for those who provide safety watch duties by the ongoing monitoring of a hot work site. Personnel undertaking this role will be assessed against Unit 3.

Appendix 1 COMPUTER BASED LEARNING PACKAGES This section sets out the principle criteria for the design and presentation of the Computer Based Learning packages. Programme Design The design of the programme should ensure the package is interactive and engaging for the learner. There must be a clear navigation system which ensures that the delegate is at ease with the learning technology and the programme should assume the learner has little or no computer experience. Screen text should be limited to summarising and for bullet points. Prompts should be included in the programme to alert the learner to the need for regular breaks about every 20 minutes. The design media used should be ‘just behind’ cutting edge IT technology but take account of the local circumstances of the client. CBT Equipment Trained facilitators should be available at remote locations to correct simple faults with the learning package and the hardware. On site learning should take place on dedicated equipment in a location suitable for the purpose.
