Identification of materials for heritage masonry introduction

Duration

12 hours

Purpose/ scope

The purpose of this standard is to provide the learner with the knowledge and skills to support the following:

Scope:

• examples and definitions of confined spaces
• specialist personal protective equipment (PPE) including practice in the use of masks, harnesses, winches, gas monitors, Escape Breathing Apparatus (EBA)
• paperwork and documentation
• safe systems of work
• monitors, bump test, peak readings, gas hazards and alarm levels
• fall arrest equipment, winches tripod and harness
• duties and responsibilities of personnel (e.g. winchman, top man, bottom man duties)
• theory and practical exercises and assessments
• emergency procedures
• the importance of reporting accidents, ill health and other incidents (RIDDOR)

Learner pre-requisites

Learners need to be in good health and physically fit

Instruction/ supervision

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

• an accredited award in education and training at level 3 or higher (or equivalent, as per requirements for approved training organisations)
• TAQA L3 Award in Assessing Vocationally Related Achievement (Assessment Only)
• at least 2 years industrial experience relevant to the scope of the standard
• a verifiable CV

Delivery

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

The learning environment, class size and learner/trainer ratio must allow training to be delivered in a safe manner and enable learners to achieve the learning outcomes, recommended maximum 1:10 for theory and 1:6 for practical.

Delivery may be in an on or off the job environment and will include opportunities to practice using specialist PPE in confined spaces, though it is recommended that this training facility should not be subject to ‘live’ unknown risks, but simulated, mitigating risk of harm.

Live site should only be used as a last resort where specific requirements need to be met, i.e. a bespoke training requirement. This will only happen if the ATO has seen and agreed to the site-specific risk assessment prepared by the site owner.

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

• face to face learning environment only (such as classroom/workshop etc.)

This standard is approximately 55/45 theory/practical training

This standard is considered to be set at an entry level

Assessment

Formally Assessed

For the successful completion of training, learners must complete an end of course practical assessment and knowledge test that measures all learning outcomes and has a pass criteria

Methods of assessment considered appropriate for training delivered against this standard are:

• multiple choice questions
• short answer questions
• practical assessment

Practical assessment pass criteria for this standard:

• as outlined in the individual learning outcomes

Where this training is assessed using multiple-choice questions, all learning outcomes must be covered over [15] questions and learners are required to achieve an overall pass mark of at least 75%.

and

Where this training is assessed using short answer questions, all learning outcomes must be covered over [15] questions and learners are required to achieve an overall pass mark of at least 70%

Quality Assurance

Assured

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

Renewal every 3 years

Classification

Mandatory Renewal
