UEEHA0027 — Manage continuous supervision inspection of electrical installations for hazardous areas

Elements & performance criteria

Performance evidence

• Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria on at least two separate occasions and include: - determining the viability of the continuous supervision inspection for a given hazardous area including: - assessing the availability of experienced personnel in relation to the particular hazardous area electrical installation - evaluating the scope of equipment to be considered under continuous supervision based on factors that can affect explosion-protection integrity, frequency of attendance, specialist knowledge, workflow and location of equipment - determining the frequency and grade of inspection and the content of reporting to enable meaningful analysis of equipment performance
• Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria on at least two separate occasions and include: - developing a continuous supervision inspection process for a given hazardous area including: - making available updated documentation necessary for inspection (and maintenance) in the continuous process including: - zone classification and, where included, equipment protection levels - equipment group and temperature class or maximum surface temperature - equipment characteristics - records to enable the explosion-protected equipment to be maintained in accordance with its type of protection - copies of previous inspection records - selecting skilled personnel to carry out inspection in the continuous supervision process based on job and regulatory requirements to undertake the extent of inspection work and the candidate’s: - understanding of the concept of continuous supervision and the need for any reporting or analysis function - knowledge of the explosion-protected equipment within their area of responsibility - previous experience in hazardous area inspection and maintenance - establishing the initial and refresher training and assessment program and records to ensure the appropriate level of knowledge and skills of personnel undertaking inspections is maintained - developing a document system to provide information of inspection (and maintenance) activities
• Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria on at least two separate occasions and include: - implementing and managing a continuous supervision process for a given hazardous area including: - providing adequate time and readily available technical support for inspections to be carried out - reviewing and analysing documentation to verify that the process is being followed and to ascertain its effectiveness - taking action to address any deficiencies found
