The heating sys tem must be such that no part of the lading is heated over 130" F., and con forms to 5 393.77 of this title. (3) Pyroforic liquids in cylinders. Cylinders containing pyroforic liquids, n.o.s,, unless packed in strong wooden boxes and secured therein to protect valves, must be loaded with all valves and safety relief devices In the vapor space, and must be secured so that no shifting will occur in transit. (c) Packages tearing labels must be loaded so they cannot fall and other packages cannot fall onto or slide against them. This requirement does not pre clude the use of loading methods that are designed to permit limited movement of the load and that are approved in writing by the Federal Railroad Admin istrator. Packages bearing markings "This Side Up" or "This End Up" must to so leaded. Hazardous materials for which a flammable liquid, flammable gas. flammable solid, oxidizer, nonflam mable gas, or a corrosive label (liquids only) is prescribed herein must not be loaded In the same car with explosives named in 173.53 to 173.87 of this sub chapter. (See loading and storage-chart 5 174.538.) Packages bearing a flammable solid or an oxidizer label must not be loaded in the same end of a car with packages bearing a corrosive label 'liquids only), except that shippers leading carload shipments who have ob tained prior approval from the Depart ment. may load materials together when it is known that the mixture of contents would not cause a dangerous evolution of heat or gas. (d) Metal barrels or drums containing flammable liquids may be loaded on steel gondola or flat cars or into stock cars, but must not be loaded into hopper bot tom cars. (e) Empty cylinders, barrels, kegs, or brums, previously used for the shipment any hazardous material as defined in ?art 173 of this chapter, must have all 'pennies Including removable heads .'.in " and vent holes properly closed be'or" being offered for transportation -mall quantities of the material with which containers were loaded may re main in "empty" containers and when the vapors remaining therein are un stable. it is permissible to add sufficient inert gas to render the vapors stable. (1) They may be loaded in open or stock cars when desired. Cars should not be placarded but lighted open-flame lanterns or other open-flame lights should be kept away. (f) Carboys previously used for the shipment of corrosive liquids when pre sented to carriers for transportation in carload or less-than-carload shipments as "empty" carboys, must be thoroughly (completely) drained. Whenever prac ticable they should not be loaded with valuable or perishable freight. (g) Matches: Carload lots of strikeanywhere (friction) matches must be loaded as compactly as possible to avoid motion within the car, especially length wise of the car. Protruding nails, metal band anchors or other projections on sidewalls, ends, door posts, studding, or car floors liable to puncture packages must be removed or adequately covered to prevent damage to containers of matches. Car doorways should be boarded on the inside to keep packages from contact with the doors, and tne inside lining of the car should be supple mented when necessary by strips nail-d to the car and close enough together to keep the boxes from being jammed against the studding and broken by high pressures on small areas. The strong est dimension of the box should be loaded lengthwise of the car. Partial layers of boxes should be interlocked with the lower layers. The cars used should be made secure against the en trance of sparks or rain and should be the strongest cars available. (1) [Reserved] (2) Carload lots of strike-anywhere matches handled subject to stop off privileges must be loaded In accordance with paragraph (g) of this section and when necessary the load must be re arranged and/or blocked and braced by each consignee before forwarding, (3) Less-than-carload lots of "strlkeanywhere" matches should be carefully loaded so that they cannot fall and so that other packages of freight cannot fall on or injure them. Whenever prac ticable the packages of matches should be placed to facilitate ready removal In case of fire. A smoking box of matches should not be broken open; the fire will cease of itself if air can be kept from it.  174,532 Title 49--Transportation (4) Carload or less-than-carload lots the liquid from a broken carboy will dm- of "strike-anywhere" matches which toward the doorway and outside the c-, have been damaged by Are, or by water The space between the strips and : in extinguishing a Are, in transit or on floor braces or blocking used for stay-.- carrier's property, must be reloaded In the carboy boxes must be covered properly prepared cars, and braced or at least 1 inch thickness of clean blocked before being forwarded to des tination. to freight claim department or claim adjusters, or to original shipper or other parties for salvage.
