posted at conspicuous locations to enable quick hazard identification for emergency <br />response crews. The two 200 - gallon waste oil tanks adjacent to the "oil room" need <br />secondary containment having a 250 - gallon capacity and the ability to drain <br />accumulated rainwater. And finally, all flammable liquids (not including bulk oils <br />and greases) should be kept in flammable liquid storage cabinets. One cabinet can <br />store up to 60 gallons, and three cabinets can be kept in one room. Alternatively, <br />one room can have groups of three cabinets, as long as these groups are separated <br />by at least 100 ft. <br />POOLS -- FINDINGS <br />Amazon <br />This is the oldest of the three city pools and also stores and uses the most 150 -1b. <br />chlorine cylinders (13 were present during the inspection). In the chlorine storage <br />shed, there are four cylinders in use at any one time, and these four tanks feed into <br />two "chlorinators" that are designed to stop the flow of gas immediately in the event <br />of a downstream leak in the piping. The shed has cinder -block walls and a wooden <br />ceiling with several holes, and no mechanical ventilation; it is therefore hard to <br />predict where chlorine from a leak "upstream" of the chlorinator would migrate. <br />This shed has no chlorine detection system or treatment system, and is not <br />sprinklered. In addition, I noted significant corrosion on some metal parts in this <br />room, probably the result of hydrochloric acid (formed when chlorine gas <br />combines with water). <br />Echo Hollow <br />The Echo Hollow storage shed contains eight chlorine cylinders, one of which is <br />used for the indoor pool, and two of which are used for the outdoor pool. All <br />cylinders in use are hooked up to tank- mounted chlorinators that are supposed to <br />cut off flow in the event of a leak. This small room of cinder blocks and bricks has <br />void spaces that could permit leakage from a cylinder to enter the adjacent shop or <br />electrical room. Mechanical ventilation is hooked up, but must be switched on <br />manually. This shed has no chlorine detection system, treatment system, or <br />sprinklers. <br />S heldo n <br />The smallest of the three facilities, Sheldon's storage shed contains four 150 -1b. <br />cylinders, with one being in use at any one time. The cylinder in use is hooked up to <br />a chlorinator. This building appears to be sealed along the walls and ceiling, but the <br />MEMO - CITY FACILITIES <br />p. 3 <br />
