Ten feet for vaporizers having a capacity of 15 gallons per hour or less vaporizing capacity. Never use a damaged cylinder. Due to the hazards propane tanks present, OSHA (Occupational Safety and Health Administration) has put forward a lengthy list of requirements for proper storage, handling, and transfer of propane and other Liquefied Petroleum gases. The filling connection shall be fitted with one of the following: Combination back-pressure check valve and excess flow valve. Ventilation, adequate - when specified for the prevention of fire during normal operation, ventilation shall be considered adequate when the concentration of the gas in a gas-air mixture does not exceed 25 percent of the lower flammable limit. No drains or blowoff lines shall be directed into or in proximity to sewer systems used for other purposes. Container valves must be protected while in storage by setting them into the containers recess to prevent the possibility of being struck if the container is dropped, or by fastening to the container a ventilated cap or collar that is constructed so that a blow would not be transmitted to a valve or other connection. Vapor shall be piped into buildings at pressures in excess of 20 p.s.i.g. Never store below ground level, as any leakage will collect at low levels. Air flow ratings can be converted to ratings in cubic feet per minute of liquefied petroleum gas by dividing the air ratings by the factors listed below. ; Tanks 125-500 gallons water capacity: must be placed a minimum of 10 feet from a building. Remove the empty cylinder, using both hands (empty cylinders can be heavy). Any damage to the coating shall be repaired before backfilling. Understanding proper propane storage cage requirements can help ensure the safety of your employees. Gas or liquid shall not be vented to the atmosphere to assist in transferring contents of one container to another, except as provided in paragraph (e)(5)(iv) of this section and except that this shall not preclude the use of listed pump utilizing LP-Gas in the vapor phase as a source of energy and venting such gas to the atmosphere at a rate not to exceed that from a No. Containers which may contain liquid fuel before being installed under ground and before being completely covered with earth are to be considered aboveground containers when determining the rate of discharge requirement of the relief valves. The valves must always be closed and, if required, sealed with a plug even if the cylinders are empty. Gaging devices shall have a design working pressure of at least 250 p.s.i.g.
