SN instructed to keep oxygen away from any open flame to include smoking and also in home pilot lights such as stove, furnace and water heater. Oxygen produced from concentrator and oxygen tanks is flammable. Do not use vaseline or petroleum based, products as these can cause irritation and skin complications. Avoid using aerosol sprays. Post no smoking/no Open Flame signs. Use caution with oxygen tubing so you do not trip over it or become entangled in furniture. Do not try to repair broken equipment on your own. Request this service from the oxygen provider. Notify the local fire department, gas and electric companies and telephone company when home oxygen therapy is started. Request a "priority service listing". This is for those times when there is a power or telephone failure or repairs are needed on any utility.
