Newly Cited AHCA Deficiencies and How to Correct Them
Recently a facility was cited for two improper connections regarding waste gas and a vacuum hose. Reviewing the two scenarios below along with understanding what is stated in the code and what is implied, will help equip you with the knowledge needed moving forward regarding the areas discussed.
In the first scenario, the facility had a waste anesthesia gas disposal (WAGD) with the correct hose and attachments (Purple and non-interchangeable). Seemingly they met the requirements, however, the problem was upon receipt of the purple WAGD hose, it was too long, so they modified it. Their solution of cutting the hose to the needed length and reattaching it to the scavenger resulted in improper field modification. By cutting the hose to length the crimped end was cut off and the hose was pushed back on the scavenger connection. The solution we recommend is instead of cutting the hose, coil the hose to accommodate your specific need.
Secondly, and more frequently, the vacuum hose which attaches to the rear of the anesthesia machine was not properly secured. There are many anesthesia machines that are only supplied with a barb in which you slide the vacuum hose onto. It too must be secured to prevent the hose from being pulled off during any movement of the equipment. The proper solution would be using a metal retaining hose clamp for proper installation and security. Consideration should be made for “sharp” or protruding edges.
NFPA 99 (2012 &2015) 5.1.5.6, 5.1.5.7 and 5.1.5.16.1 speak directly to the hoses and their connections requiring them to be gas specific and non-interchangeable. What the code does not directly speak to, is the vacuum hose and its connection to the anesthesia machine. This is where you must refer to the manufactures recommendation and guidance. In my opinion (and the inspector’s obviously) the 50 cents and 1-minute installation is worth the peace of mind of ensuring a secured connection.
