City & Guilds have developed the 2078-02 Ammonia Refrigerant Handling with the Refrigeration Industry Board (RIB) to reflect the standards of BSEN 378 (Safety Aspects in Design, Construction and Installation of Refrigerating Appliances).
With the increasing number of plants turning to ammonia refrigerant, and it’s potentially fatal consequences, the correct training in safe handling is essential.
This course is currently always held on site with access to suitable ammonia plant required Up to 6 engineers can be assessed per course.
This course is not suitable for inexperienced engineers. Knowledge of the use of a charging manifold and gauge lines is implicit.
For inexperienced personnel, this 2-day course can be taken in conjunction with the 1 day Introduction to Ammonia
Objective
To achieve the City & Guilds 2078 02 qualification.
Methodology
Candidates for the refrigerant handling assessment must demonstrate that they are competent to handle refrigerants, including both charging and recovery. They must also show their awareness of the hazards of using such refrigerants to themselves, to other people and to the environment. No formal qualification needs to be held by the candidate, All underpinning knowledge will be provided be a brief presentation and the comprehensive notes supplied.
A presentation / discussion session will be followed by one-to-one assessments. Theory will be tested by means of verbal questions.
Practical skills will be tested by means of a practical demonstration by the candidate. Candidates must demonstrate that they are competent to handle refrigerants, including both charging and recovery. They must also show their awareness of the hazards of using such refrigerants to themselves, to other people and to the environment.
Synopsis
The course will include the following topics:
- Use of safety equipment and the implications of safety standards and legislation.
- Identification of type, state and condition of refrigerant.
- Storage and movement of refrigerant cylinders.
- Decanting of refrigerant.
- Processing of systems before refrigerant is charged.
- Charging liquid and vapour refrigerant into new and existing systems.
- Recovery of refrigerant from systems.
Additional topics required for Ammonia
- Breaking into a system
- Purging lines / system
- Risk Assessment
- Work Permits
- Emergency Procedures / Equipment
All the above processes must be carried out with the minimum emission of refrigerant to the atmosphere and without danger to the candidate or others.
