Ars†28-797 school crossings

The highway commission may establish crosswalks in front of each school building or school grounds abut­ting thereon where children shall be required to cross the highway or street. Additional crossings across highways not abutting on the school grounds may be approved by the highway commission upon appli­ca­tion of school authorities. The district should assure that adults are used as guards at no abutting school crossings.

When school crossings are established, do school authorities cause to be placed within the highway portable signs indi­cating that school is in session, placed not to exceed 300 feet each side of the school crossings, and "Stop When Children In Crosswalk" signs at school crossings, and do school authorities maintain these signs when school is in session and cause them to be removed immediately thereafter? Notwithstanding any other law.

[ ] Yes [ ]No

Ars† 28-857 overtaking and passing school bus (2006)

Does every bus used for the transportation of school children bear upon the front and rear of such bus a plainly visible sign containing the words "School Bus" in letters not less than eight inches in height, and have a signal with the word “stop” printed on both sides in white letters not less than five inches high on a red background. When a school bus is being operated upon a highway for purposes other than the actual transportation of children either to or from school, are all markings indicating "School Bus" covered or concealed?

Is every bus used for the transportation of school children equipped with a signal with the word "Stop" printed on both sides in white letters not less than five inches high on a red background, and is the signal an 18-inch reflectorized octagon sign manually operated by the operator of the school bus in such manner as to be clearly visible from both front and rear when extended from the left of the body of the bus?

Does the district ensure that operators of school buses display the stop signal and alternately flashing lights if passengers are being received or discharged while the bus is stopped on the roadway?

[ ] Yes [ ]No

Ars† 28-900 rules relative to school buses

Does the district, in order to reduce the interior temperature of a school bus, allow the exterior top of the bus to be painted white? The white area shall not extend beyond the center clearance lights, front and rear, and shall not extend below a line five inches above the top of the side windows.

[ ] Yes [ ]No

Ars† 28-901 maximum number in school bus; exceptions; receiving or discharging school children at school

Does the district assure that no school bus shall be operated on a public highway while carrying more than can be properly seated, nor while any person is standing therein, except for the purpose of conducting drills under school regulations and in the emergency evacuation or dispersal of pupils and school personnel?

[ ] Yes [ ]No

Ars† 28-930 special lighting equipment on school buses

Does the district ensure that bus operators do not operate any alternately flashing warning signal light on any school bus except when the school bus is within 100 feet of a stop, or is stopped, on a highway for the purpose of permitting school children to board or alight from it?

what about nanotechnology for water purification
RAW Reply
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
