Ground gas protection measures - getting it right

Standard details

CITB has developed this standard in discussion with industry

Duration

Minimum 1 day of 6 learning hours

Purpose/scope

The purpose of training delivered against this standard is to provide candidates with the knowledge of general ground gas protection.

The scope of this standard covers:

• hazard of ground gases
• principles of ground gases
• guidance and regulation
• principles of gas protection: design, ventilation, and membranes
• verification
• project sign-off role
• implications and requirements of CIRIA C735
• common issues
• verification engineers and installation competency
• damage by follow-on trades
• good practice gas membrane installation
• jointing membranes, detailing, corners, and retrofitting
• installation practices (NOS QCF units 612 and 613).

Occupational relevance

Training delivered against this standard would be relevant to the following occupational groups:

• operative and craft
• supervision
• management and leadership.

Candidate pre-requisites

There are no candidate pre-requisites as part of this standard. However, candidates should have some technical or practical experience of working in a related environment.

Instruction/supervision

As a minimum, course instructors must be able to demonstrate that, in relation to this standard, they have:

• A train the trainer or instructional techniques course certificate
• Successfully completed training to this standard 
• At least 2 years relevant industrial experience
• A verifiable CV.

Delivery

The following method may be used in the delivery of this standard:

• classroom
• e-learning
• blend of classroom and e-learning

All materials and equipment must be of a suitable quality and quantity for candidates to achieve learning outcomes, and must comply with relevant legislation.

The class size and candidate/instructor ratio must allow training to be delivered in a safe manner and enable candidates to achieve the learning outcomes.

This standard is considered to contain 51 per cent or more theoretical learning.

Assessment

For the successful completion of training, the trainer will be required to make a declaration of the learner’s contribution during the course and that they are confident the learner has understood the content of the course.

Quality assurance

Quality assurance against this standard will require initial approval of the training organisation and their content mapped to the standard. 

CITB will also conduct an approval intervention, either desk-based or centre visit, to ensure the training organisation can meet the requirements of the Training Standard. 

Approved training organisations (ATOs) will be required to present information on records of training and assessment upon request to CITB for desk-based analysis. They will also be visited annually by the CITB quality assurance team.

Renewal/refresher

There are no mandatory renewal or recommended refreshment requirements for this standard.

Approval date

November 2018

Review cycle

Either on request or in 3 years from approval date.
