A report has been received in the Ministry of Health from a medical institution regarding a nitrous oxide (laughing gas – N2O) gas cylinder that has undergone unauthorized conversion and was supplied with an oxygen connecting valve.
The Ministry of Health has commenced widespread investigations to locate additional canisters of this type.
In order to complete the investigation process, the Ministry of Health asks dentists or other doctors who have gas cylinders in their clinics for medical use to ensure that the gas cylinders in their possession, with an emphasis on nitrous oxide cylinders, are in proper working order and have not undergone any unauthorized conversion.
It is important to note that no mishap or error has been reported to the Ministry of Health in the administration of the gas to patients, but in order to prevent possible error in administration of gas, we request that you act in accordance with the following instructions:
