Summary A previously unreported hazard of free‐standing ‘Tec’ type vaporizers relating to their positioning downstream of the oxygen jlush is presented. Three Enfluratec Mark III vaporizers were studied; measurement of delivered enjlurane concentration was performed at a flow rate of 8 litres/minute, during and after the application of the oxygen flush upstream of the vaporizer. The maximum difference between the dial setting and the measured vapour concentration occurred when a 5‐second flush was applied to a vaporizer set at 0.2 volume %, the peak vapour concentration recorded being 2.3%. Other hazards of free‐standing vaporizers are discussed and ways of avoiding these hazards considered.
