If you fit a valve marked “Air” on an Oxygen cylinder, it might cause confusion during servicing and the technician may not oxygen clean the valve and cylinder. Fitting a valve marked “Air” onto a cylinder that will be used for Oxygen or Oxygen enriched gas would be questioned in UK and EU centres.] 的热门建议 |
