        • No, however we would suggest that you undertake a Confined Space Course which covers the use of gas monitors. Our sister company Citrus Training offers these courses.

        • Taking into consideration the ATEX directive, manufacturer recommendations and your own company risk assessments, it is recommended that you bump test your monitor before every use, it is true that the law is not clear and doesn’t use the all-important word “MUST” and the regulation only surrounds flammable gases, not toxic, but you can guarantee that the authorities would want to see evidence of such testing should the worst happen!
