This document discusses occupational health and safety requirements for working with electrical equipment in hazardous locations. It outlines the legal responsibilities under the Occupational Health and Safety Act of 1993, including requirements for inspections, training, and certifications. The document proposes a competency and training framework with multiple levels to ensure workers have the proper qualifications and experience before working with electrical equipment in explosive atmospheres. It emphasizes the importance of both theoretical training and practical experience, as well as continuing education, for maintaining safety.

6. ALARMING FACTS
 Millions are spend on optimizing plants, BUT very little is
spend on training staff operating and maintaining these
technical advanced plants.
 Emphasis on qualification, but competence, practical
assessment, and refresher training is neglected.
 Pool of “Ex” experts shrinking due to the lack of formal
qualification structures for the competent ‘old hands’ and
youngsters entering this field…

7. WHY REFRESHER TRAINING ??
 Legal requirement
 Continuous staff competence improvement
 Changes to standards/codes occur frequently and needs to be
understood and interpret by staff
 Training is a constant and on-going process that will never end
 Changes in technology to plant processes and maintenance
activities, needs to update current practices

DIPLOMA

25.  Practical experience is crucial, but the application there-off
is more important.
 Lack of skilled, competent workforce is everyone's problem
 Youngsters must know the risks involved in hazardous
locations, only achievable by proper training, and practical
exposure
 Don’t forget the ‘CURRENT XPERTS’ they also need
proper training
 How do you validate saving cost in lea of safety and
training

27.  Ensure all training attended to be fully
accredited.
 Ensure training covers both practical and
theoretical applications
 Have a training programme for each employee
(PDP)
 Managers also needs to attend technical training
 Include the ‘CURRENT XPERTS’ !!!!!!!!!!
 Have non technical staff also attend training
(buyer, secretaries, operators, etc..)
