Probably 300' of the 34BA Bright Yellow Breathing Hose from Amron International. Or from a competitor if I can find one as the one from Amron is out of stock until Feb 8. I am also seriously thinking to have my existing hose analyzed by a lab to see what if any derrogatories exist. I am very curious about this entire hose business and not looking for shortcut just clarity. Is it possible that the cost to get approvals from OSHA, etc....is not worth it for some industrial hose manufacturers and maybe their hose is perfectly okay. I have the money to do this research so why not. Reports of the study and findings will be made avaailbe here at $50 per (hahahah kidding). Thanks fstbttms for lighting a fire under my you know what.
There are a bazillion kinds of hose connectors and you will find them at Home Depot, Lowes and hose suppliers. Most hose will have 1/4" male ends which is just fine as you will find all the connectors you will need for adding hose, keeping the hose from twisting (swivel connector). I like lots of hose length just in case I need to go deeper or want more range from the sled or tank location. I have never encountered any breathig hampering from this and I have gone out 150' of hose
In January 2006, the European Union placed a ban on six types of phthalate softeners, including DEHP (diethylhexyl phthalate), used in toys. In the U.S. most companies have voluntarily stopped manufacturing PVC toys with DEHP and in 2003 the US Consumer Product Safety Commission (CPSC) denied a petition for a ban on PVC toys made with an alternative plasticizer, DINP (diisononyl phthalate). In April 2006, the European Chemicals Bureau of the European Commission published an assessment of DINP which found risk "unlikely" for children and newborns.
Other vinyl products including car interiors, shower curtains, and flooring initially release chemical gases into the air. Some studies indicate that this outgassing of additives may contribute to health complications, and have resulted in a call for banning the use of DEHP on shower curtains, among other uses.[26] The Japanese car companies Toyota, Nissan, and Honda have eliminated PVC in their car interiors starting in 2007.
In 2004 a joint Swedish-Danish research team found a statistical association between allergies in children and indoor air levels of DEHP and BBzP (butyl benzyl phthalate), which is used in vinyl flooring.[27] In December 2006, the European Chemicals Bureau of the European Commission released a final draft risk assessment of BBzP which found "no concern" for consumer exposure including exposure to children.[28]
In November, 2005 one of the largest hospital networks in the U.S., Catholic Healthcare West, signed a contract with B.Braun for vinyl-free intravenous bags and tubing.[29] According to the Center for Health, Environment & Justice in Falls Church, VA,[30] which helps to coordinate a "precautionary" PVC Campaign,[31] several major corporations including Microsoft, Wal-Mart, and Kaiser Permanente announced efforts to eliminate PVC from products and packaging in 2005.[32] Target is reducing its sale of items with PVC.[33]
The State of California is currently considering a bill that would ban the use of PVC in consumer packaging due to the threats it poses to human and environmental health and its effect on the recycling stream.[53] Specifically, the language of the bill analysis[54] stipulates that EPA has listed vinyl chloride, a "constituent element" of PVC, as a carcinogen[citation needed]. It also further cites that there are concerns about the leaching of phthalates and lead from the PVC packaging.
