You do not have to have safety courses, CPR or first aid to meet accreditation requirements. ISO 17025 accreditation does not specifically include Health and safety requirements. As a laboratory you should of course, comply with all Health, Safety and Environmental protection regulations of your country; and personnel need suitable training and knowledge. Typically these requirements are covered under a separate programme and documentation, usually via a policy and manual. This means that the accreditation body will not directly assess the laboratory on these issues, unless linked to an ISO 17025 requirement that could jeopardise the consistent, impartial operation to produce valid results – for example cross contamination. What ISO 17025 does require, stipulated in clause 5.4, is that Laboratory activities must be carried out in such a way as to meet the requirements of regulatory authorities, organizations providing recognition and customers. These requirements could be integrated into one management system or could be separate.
