Layers of protection analysis (LOPA) enhances the results of PHA studies by providing more objective estimates of the risks of hazard scenarios. Such risk estimates play a critical role in decisions on the adequacy of the safety of processes. Consequently, it is essential that individuals who lead LOPA studies meet a standard for competence. Three increasing levels of competency are offered: Practitioner, Specialist and Expert.

This certification is intended for a process safety professional who is ready to take the role of team leader for LOPA studies. A Practitioner has a minimum of one year of relevant experience. This level of certification indicates that the professional has the knowledge and understanding to lead LOPA studies competently.

Primacert expects that a Certified LOPA Practitioner using the designation CLP^® can demonstrate competency by meeting the following requirements:

• A degree from an accredited university or college in a relevant technical discipline. At a minimum, degree includes three years relevant, full-time tertiary education.
• If you do not meet these requirements, you may contact PCS to inquire about alternative qualifications.

• A minimum of one year of recent and relevant work experience.

• Successful completion within the last three years of a training course designed to teach participants how to conduct a LOPA study, such as Primatech's Layers of Protection Analysis for Process Safety Management.

• Two references from supervisor / manager / peer who can attest to academic qualifications, work experience and professional ethics.

• Successful completion of the Primacert examination for CLP^®.
• For a list of examination topics, see LOPA Examination Topics.

• Certification is valid for three years.
• For recertification requirements, see Recertification Requirements for CLP^®.
