The majority of foundries specialize in a particular metal and have furnaces dedicated to these metals. For example, an iron foundry (for cast iron) may use a cupola, induction furnace, or EAF, while a steel foundry will use an EAF or induction furnace.
PROCEDURE. If you will be giving the enema to yourself the first thing you should do is set up the area for the procedure. Make sure the hook is suspended at the proper height (18-24 inches above the rectum). Then place a pad or bath towel where you will be lying down.
Enema administration involves instilling a solution into the rectum and colon. In a retention enema, the patient holds the solution within the rectum or colon for 30 minutes to 1 hour. With a cleansing enema, the patient expels the solution almost completely within 15 minutes. Both types of enema stimulate peristalsis by mechanically distending the colon and stimulating rectal wall nerves. Enemas are used to clean the lower bowel in preparation for diagnostic or surgical procedures; to relieve distention and promote expulsion of flatus; to lubricate the rectum and colon; and to soften hardened stool for removal.
