Redmond said money for a new addition to Taft High School, 5625 N. Natoma would not be made in the 1971 budget to help with the repairs. "The toilets tat the Delano School were inspected by the supervising engineer on Dec. 16, 1970. He found them to be clean and odor-free," Lederer said.

"However, it is recognized that the toilets are very old, and Delano has a top priority for toilet rehabilitation in the 1971 budget." More than $70,000 has been set aside for the work, he said. He said repairs to toilet fixtures in Gray School have previously come from engineer repair expenses but this fund is now depleted. Gray PTA parents complained that washroom renovation had begun but stopped in recent months. Hirsch Needs Electrical Work Hirsch High School PTA members said their repeated yearly requests for electrical renovation had "fallen on deaf ears." "The need for electrical rehabilitation at Hirsch has been recognized for several years," said Lederer. "It has finally been possible to make provision for an appropriation of $120,000 for this work in 1971." BY ROBERT COLVIX The Chicago Board of Education recently released reports to answer hundreds of complaints from city residents in December public budget hearings about poor classroom lighting, toilets that didn't flush and stale bread being served in free lunches.

Dr. Edwin A. Lederer, associate superintendent for operation services, In response to a complaint from Madison School PTA, 7433 S. Dorchester said day-old lunches will not be served to pupils. Mrs.

Michael West, speaking for the school PTA, complained that lunches often were served with stale bread. Parents wanted a hot lunch facility, she said. Dr. Lederer said he hopes to install a hot lunch program soon. Toilets Need Repairs In response to complaints about toilets that were not operating in schools including Delano, 3937 W.

Wilcox Gray, 3730 N. Laramie Harvard, 7525 S. Harvard Lederer said the board was trying to find money The school's PTA had complained the building was severely overcrowded and more space was needed. Postpone Overload Relief Pleas for an addition to relieve the student overload in Amundsen High School, 5110 N. Damen will go unanswered this year because of a lack of funds, he said.

The plan is, however, being considered for the future. Members of the Mount Vernon School PTA, 10540 S. Morgan who complained their yearly requests for additional classrooms have not been answered, were told that mobile units will be installed this year. Redmond said the administration estimated opening 544 school buildings for a total of 10 nights each year for PTA and local school council meetings would cost an added $400,000. The school now allows only four night meetings each year.

The board has not yet decided to allocate that sum. Many residents attending the budget hearings complained the lack of night meetings discriminates against fathers and working mothers. tends to form corrosive and gummy deposits. It also "poisons" complex air pollution control devices that will become standard equipment on all cars in a few years. The automotive industry got- a sharp reminder that day is drawing closer when Congress sent to the President on Dec.

18 one of the strongest bills in history to fight air pollution. It forbids the sale of automobiles after Jan. 1, 1975, whose emissions of carbon monoxide thru their exhaust systems have not been reduced 90 per cent below present levels. By Jan. 1, 1976, the automakers must have reduced emissions of nitrogen oxide by 90 per cent.

Lead Also Health Hazard It became clear a long time ago among automotive engineers that this kind of emission control is not possible with leaded gasoline, using current technology. In addition, some critics of lead additives assert that the 400 million pounds of lead poured into the atmosphere each year from automotive tailpipes is a health hazard. The petroleum industry is making good its pledge that unleaded gasoline will be available when cars become available to use it. Unleaded gas hit the market nationally for the first time last summer. Detroit is building new cars with air pollution control devices that can use low-octane fuel, altho an estimated 63 per cent of all cars currently in use can use lead-free gas.

Cars with high-powered engines need high-octane fuel. Sales Leveled Off "Sales of unleaded gasoline were fast at first," said Twardy. People generally were enthused about the environmental issue. But then sales leveled off as. consumers reacted to the extra cost.

"Sales are picking up again," said Twardy, "and we are adding lead-free gasoline pumps at hundreds of stations across the country every week." The installation of a third pump for lead-free gasoline at service stations, plus the need for separate handling facilities such as trucks and storage tanks also account for the higher price of lead-free gasoline, he said. These increased capital costs also figure into the cost of lcadless gasoline. But there is a bright side to all of this. It has long been known that unleaded gasoline has long been sold by Standard Oil in 25 eastern and southern slates. Bright Side Standard says unleaded gasoline gives better mileage than leaded fuels of equivalent quality, reduces maintenance costs by eliminating lead deposits in combustion chambers and on spark plugs, and extends muffler and tailpipe life by reducing corrosion.

So if you got a new car for Christmas fill it up with unleaded gasoline. People often ask why lead-free gasoline is more expensive than regular grade gasoline, usually two or three cents more a gallon. One of the reasons is that it takes five to seven per cent more crude oil to make unleaded gasoline compared with lead added to increase the octane rating, Stan Twardy, a spokesman for the Standard Oil told Life Line. But that's not all. The lead-free regular grade gasoline sold by Standard in the Chicago area is refined to the point where it is 86 to 88 octane an index of volatility.

Premium grade lead-free gasoline about 94 octane is then mixed with it to boost the octane rating of regular grade unleaded gasoline to about 91 octane. Why 91 octane? Detroit "Detunes" Cars "Because that was the minimum for modern cars to operate properly," Twardy said. However, Detroit is producing new cars with "detuned" and low compression engines that can run on low octane fuel. The point in all of this is that the octane rating of lead-free gasoline is being controled thru costly refining, instead of the use of tetraethyl lead. One of the cost factors involved here is the fact that platinum is a widely used catalyst in producing high-octane levels in unleaded gasoline.

With greater demand for unleaded gasoline, more platinum must be used to produce it. The white metal sells for $135 an ounce. Raises Octane Rating Before the concern over automotive air pollution emissions, the petroleum industry could add lead to raise the octane rating of fuel 95 octane for regular gasoline and 100 for premium. Lead also is an antiknock compound, making the fuel burn more evenly in combustion chambers. This development in 1921 was a boon to the petroleum industry, because it meant that low-grade crude oil and the dregs of the refining process could be treated with lead and become usable regular grade gasoline.

Detroit, in turn, produced high performance engines which generally required high octane fuel. Gums Up Device Enter the air pollution furor. The major push to "get the lead out" of gasoline began about two years ago with the inescapable conclusion that the lead in gasoline was gumming up the air pollution control devices that were being designed and tested to meet future and tougher air pollution regulations such as catalytic mufflers and afterburners. Gasoline thruout the country generally contains an average of about xk grams of lead per gallon, with premium gasoline containing about one-half gram more a gallon. The lead in gasoline City Planners Consider Pioneer Ideas for Including Fire Safety in Sears Tower Fitzgerald stressed that building and fire authorities do not recommend the use of elevators during a fire.

He expects the code amendment to be approved in late January and then forwarded to the mayor and the City Council. He said the National Loss Control Service Corporation, under contract to the city, and the Chicago Committee on High Rise Buildings are both studying the problem of high rise fires. Buildings has requested test results on such systems from the Otis Elevator Company, 600 W. Jackson. Fitzgerald also said the subcommittee is considering a building code amendment requiring elevator devices that would permit firemen to override elevator controls and take charge of elevators during a high rise fire.

Such systems would bring survivors to the ground floor of a burning building and give firemen greater mobility. LiV ti is CM Oil ,4 ft 11 BY FRANK ZAHOUR Two pioneer concepts in high rise fire prevention under consideration by city authorities may be built into the world's tallest building the 110-story Sears Tower planned for South Wacker Drive between Adams Street and Jackson Boulevard. A complete sprinkler system for the 1,450 foot building and the establishment of "smoke free and fire free" zones in the building are the concepts Skidmore, Owings and Merrill, building designers, and city building code officials are considering, according Joseph F. Fitzgerald, Commissioner of the City's Building Department. A Sears spokesman emphasized that the ideas are under consideration and "no firm commitments" have been made, He said Scars hopes to have "the best fire prevention system possible" in the building.

May Be Firsts Both ideas, if they arc incorporated into the building and the city building code, could be firsts in the area of high rise fire prevention. James Barrett, Chief Fire Prevention Engineer of the Fire Department's Bureau of Firo Prevention, said he knows of no major high rise that has a complete sprinkler system. Barrett said the idea of "smoke free and fire free zones" involves designing certain floors of a high rise as insulated, protected areas that would have Independent ventilation systems and provisions to protect potential fire victims. Commissioner Fitzgerald said the concept involves certain floors in a building which, during a fire, might be scaled off to act as "fire shelters." He said the concept of protecting people in a building during a fire is a relatively new one. Lindsay Orders Plans In New York, Mayor John V.

Lindsay recently ordered the development of emergency evacuation plans for all of the city's tall buildings. Discussion of the fire prevention concepts came at last week's meeting of an architectural subcommittee of the mayor's advisory committee on building code amendments. The subcommittee also discussed "heat activated" elevators and their potential threats to high rise residents during a fire. These are elevators that are activated by the heat of a finger instead of mechanical pressure. Fires May Attract A recent investigation in New York City revealed that these elevators might be drawn to the heat of fires in high rises.

The report indicated the possibility of such elevators opening on floors with fires and trapping firemen and potential survivors. However, the term "heat activated" is actually a misleading one according to Stephen J. King, chief of elevator Inspections for the Building Department. King said these type of elevators arc actually activated by ground capacitance in a system that utilizes the electrical potential of the human body. Considering Amendment Commissioner Fitzgerald said thai, contrary tft the New York report, these systems not represent a threat during a fire.
