Containers, regulating equipment, manifolds, pipe, tubing, and hose shall be located so as to minimize exposure to abnormally high temperatures (such as may result from exposure to convection or radiation from heating equipment or installation in confined spaces), physical damage, or tampering by unauthorized persons. This Technical Measures Document covers the storage and handling of toxic and flammable substances in drums and cylinders and refers to relevant codes of practice and standards. Propane cylinders must never be stored or placed in an area of. at 100 F., see subparagraph (14)(viii) of this paragraph. When a regulator or pressure relief valve is installed inside a building, the relief valve and the space above the regulator and relief valve diaphragms shall be vented to the outside air with the discharge outlet located not less than 3 feet horizontally away from any opening into the building which is below such discharge. Storage in "Special Buildings", meeting the requirements of Chapter 7 of NFPA 58 is limited to 10,000 pounds of propane. Too often, facilities using propane tanks have them stacked indoors, stored improperly and with no safety cages or protection. The cylinders should be stored in the proper orientation with the relief valve in direct contact with the vapor space in the container: Grill cylinders should be stored vertically. The device that supplies the necessary heat for producing steam, hot water, or other heating medium may be installed in a building, compartment, room, or lean-to which shall be ventilated near the floorline and roof to the outside.

Hose shall be long enough to permit compliance with spacing provisions of this subparagraph without kinking or straining or causing hose to be so close to a burner as to be damaged by heat. With notation as to whether the container is designed for underground or aboveground installation or both. Cylinders used for forklifts can be stored in either the vertical or horizontal position, but if stored . They should be placed off the ground, on top of a surface that will not burn. A shutoff valve shall also be placed at the appliance end of the intermediate branch line. Where vaporized gas on the low-pressure side of the system may condense to a liquid at normal operating temperatures and pressures, suitable means shall be provided for revaporization of the condensate. When a variable liquid-level gage is also provided, the fixed liquid-level gage will also serve as a means for checking the variable gage. If a drain is used, a means shall be provided to protect the container, adjacent containers, piping, or equipment against impingement of flame resulting from ignition of product escaping from the drain. input when used with containers having a maximum water capacity of 2 pounds. Equipment utilizing vaporizer-burners shall be equipped with automatic shutoff devices upstream and downstream of the vaporizer section connected so as to operate in the event of excessive temperature, flame failure, and, if applicable, insufficient airflow. Vaporizers of less than 1 quart capacity heated by the ground or surrounding air, need not be equipped with safety relief valves provided that adequate tests demonstrate that the assembly is safe without safety relief valves. and 14.7 p.s.i.a. Never use matches or a flame to check for leaks. 2023 Commander Warehouse Equipment | All rights reserved | Privacy A plugged opening will not satisfy this requirement. Need a custom solution? The start-to-discharge pressure setting of such relief valves shall not be in excess of 500 p.s.i.g. Vaporizers shall have, at or near the discharge, a safety relief valve providing an effective rate of discharge in accordance with paragraph (b)(10)(iii) of this section, except as provided in paragraph (d)(4)(v)(a), of this section. 8. Notice: Due to the shipping delays our lead times are increased above normal. Pressure regulating and pressure reducing equipment if located within 10 feet of a direct fire vaporizer shall be separated from the open flame by a substantially airtight noncombustible partition or partitions. With the name or symbol of the manufacturer. Openings from container or through fittings attached directly on container to which pressure gage connection is made, need not be equipped with shutoff or excess flow valves if such openings are restricted to not larger than No. For operating pressures of 125 p.s.i.g. "propane vehicle" means a vehicle that is designed to travel only or primarily on land and is propelled by an engine fuelled by propane; "retail outlet" means any premises to which the public is invited at which propane is sold and is put into the fuel tanks of motor vehicles or into portable containers with a capacity exceeding 0.5 kg. The heating medium lines into and leaving the vaporizer shall be provided with suitable means for preventing the flow of gas into the heat systems in the event of tube rupture in the vaporizer. Not something anyone wants to see happen. Although the list of OSHAs storage and handling regulations is very long, the basic rules of handling and storing propane can be condensed as follows: Whether using propane at home, on holiday or at work, following the manufacturers instructions can keep everyone safe. NO SMOKING signs shall be posted on the exchange cage and within 25 feet of the surrounding area. A storage container shall not exceed 90,000 gallons water capacity. This coating shall be equivalent to hot-dip galvanizing or to two coatings of red lead followed by a heavy coating of coal tar or asphalt. Tank heaters shall be permanently marked with the name of the manufacturer, the rated B.t.u. Cylinders must be protected from falling by using a chain or another adequate support systems. This specific container style must meet OSHA fire cabinet regulations. Containers shall not be reinstalled unless they are requalified in accordance with DOT regulations. Vaporizers having a capacity greater than 100 gallons per hour shall be located at least 15 feet from container shutoff valves. for underground containers. Pressure regulating and control equipment when located downstream of the vaporizer shall be designed to withstand the maximum discharge temperature of the vapor. when starting their barrels. Do forklift propane tanks need to be recertified? The track of tank car siding shall be relatively level. Vaporizer houses shall not have unprotected drains to sewers or sump pits. Do not let the cylinder get too hot. This could cause injury to the eyes or body and create a fire hazard. Fire extinguishers should be placed within easy access of propane storage. Containers and regulating equipment installed outside of buildings or structures. Inspecting a full propane cylinder after its removal from the facility's cage, typically installed by a propane provider, will help ensure good working use. The NFPA 704 sign shall be a minimum of one foot square. Do not smoke while handling or transporting cylinders. In buildings devoted exclusively to gas distribution purposes, the space above the diaphragm need not be vented to the outside. Containers of more than 30 gallons water capacity and less than 2,000 gallons water capacity, filled on a volumetric basis, and manufactured after December 1, 1963, shall be equipped for filling into the vapor space. On underground containers of more than 2,000 gallons water capacity, the discharge from safety relief devices shall be piped vertically and directly upward to a point at least 7 feet above the ground. Locked & Loaded. Systems - an assembly of equipment consisting essentially of the container or containers, major devices such as vaporizers, safety relief valves, excess flow valves, regulators, and piping connecting such parts. O. Reg. PLEASE CONTACT US FOR CURRENT PRICING, Need New Forks for a Forklift? melting point) which will cause the internal valve to close automatically in case of fire. That's why our gas cylinder storage cages come with a lockable latch, mesh sides and front for great ventilation and a solid roof that will protect the cylinders from damage. The start-to-discharge pressure setting shall be such as to protect the components involved, but not less than 250 p.s.i.g. With the name of the manufacturer; rated BTU input to the burner; the area of the heat exchange surface in square feet; the outside surface of the vaporizer in square feet; and the maximum vaporizing capacity in gallons per hour. Tank heaters shall be provided with a means for manually turning off the gas to the main burner and pilot. Designed with safety and OSHA regulations in mind, our Gas Cylinder Cages have mesh sides and front door for proper ventilation, with a solid roof that protects cylinders from falling objects. If this distance cannot be achieved, a barrier wall (at least 1 metre higher than the tallest cylinder) can be used to achieve the segregation. Different types of cylinder and gas property should be stored separately, at least 3 metres apart. The minimum nominal wall thickness of copper tubing and aluminum alloy tubing shall be as specified in Table H-24 and Table H-25. Blower and radiant type heaters shall not be directed toward any LP-Gas container within 20 feet. The connections or line including valves, fittings, etc., being protected by an excess flow valve shall have a greater capacity than the rated flow of the excess flow valve. The cylinders must be upright and secured.
