Compex Hazardous Areas Refresher – Gas

COMPEX HAZARDOUS AREA REFRESHER

AIM
To update and refresh knowledge and skills of electrical and instrument apparatus within potentially explosive gas atmospheres.

Pre-Requisite
Candidates must hold a valid CompEx certificate of core competency.

Please note: Should a certificate state the reference RNC or a company’s name, eligibility to attend a refresher must be checked with the Sales Team before booking.

If in any doubt whatsoever that your qualifications do not satisfy the pre requisite criteria please place a query with the sales team on enquiry if possible. By booking you are stating that you meet the pre-requisites.

Course Duration
2 days.

Maximum Number
6 persons.

Training Aids
Lecture notes, audio-visual presentation, demonstrations and practical exercises.

Assessment
A multi-choice paper and practical assessment on an installation simulator.

Certification
On successful completion of the refresher and update course, and competence validation tests, delegates will be awarded a renewal certificate of competency from JT Ltd. In the instance of failure of any component of the competence validation tests, a letter of failure will be issued and a refresher re-sit will need to be booked. All results are issued by JTL, and are not available to NETA. Waiting time for certification/results is dependent on JTL workloads.

Please note: The CompEx Certificate of Core Competence is valid for 5 years from the date of issue and must be refreshed before expiry. JTL recommend that delegates attend the refresher at least 3 months prior to expiry to avoid a gap in certification and the risk of having to sit the full 5 day course to gain certification.
