Focus on: Compressed Air Process, Controls & Plant reviewed and kept up to date). This is where it is advisable to consult with a proven service provider, such as a verified BCAS member - who can help to determine which of the regulations apply to the pressure equipment subsequently provided. In addition, the user of an installed system and the owner of a mobile system must ensure that the system is kept properly maintained and in good repair, to prevent danger. Written Scheme of Examination A key component of the PSSR is that a Written Scheme of Examination (WSE) is required. The process of drafting a WSE is laid out in the regulations, as is the process for the periodic examinations, reporting and record keeping of pressure systems. Also detailed are the attributes required for the persons that are permitted to certify and carry out examinations under a Written Scheme of Examination. In both instances, these are referred to as Competent Persons. Competent persons So, what is a ‘Competent Person?’ The terms actually refer not to the individual employee that carries out duties under the Regulations but to the body which employs the person charged with those duties. Thus, the definition of competent person makes it clear that the legal duty to comply rests with the employer, and not with an individual, unless that person is self-employed. To be considered a competent person for the purposes of carrying out the examination or certifying the Written Scheme of Examination, the engineer should have sufficient practical and theoretical knowledge and actual experience of the type of system under examination. This will then enable any defects or weaknesses to be identified and an assessment made of their significance in terms of the integrity and safety of the equipment. It is important to remember that where certification of a Written Scheme of Examination is required, the regulations state that suitable, competent persons are qualified to incorporated of chartered engineer level. More information can be found in the BCAS Factsheet 315. In all cases it is the responsibility of the owner/user to ensure the scope of the scheme is appropriate - yet it may well be the case that that this is outside of your experience.
