At the time, thousands of the grilles were being installed at Los Angeles schools with $14 million from the Proposition BB bond issue.
Unknowingly risking the welfare of children, district officials were concerned about vandalism and burglaries when they ordered grilles bolted to the window frames of portable classrooms at 102 campuses to protect classroom equipment.
Maintenance workers began to double back to retrofit the grilles bolted to exterior window frames last April.
Modifications would be made to existing grilles as soon as officials from the district and the Los Angeles city Fire Department can design an escape lever.
The committee recommended that the district continue mounting the fixed grilles outside classroom windows, leaving one window free for the new, releasable screens.
Under the state fire code, classrooms that have security grilles over every window without fire sprinklers and only one door need an interior safety latch on the window farthest from the door.
Fire, building and safety experts will testify about the safety of the grilles.
But he said it falls short of a resolution he plans to introduce at today's committee meeting calling for a temporary delay of new grilles and modification of existing ones.
But Wendy Shepherd, a resource teacher at San Jose Street Elementary School in Mission Hills where the grilles already are in place, said she was disappointed that the moratorium was not issued sooner.
He urged the district to impose a moratorium on the grilles unless they have a safety catch.
The Board of Education safety committee plans on conducting an investigation into the grilles, but the board did not enact a moratorium Monday because it would be premature, said Eric Nasarenko, a spokesman for the Los Angeles Unified School District.
The installation of the security grilles and whether they constitute a fire concern is something that the district is committed to reviewing and will do so under the direction of school board member Valerie Fields' safety committee,'' Nasarenko said.
Paid for with Proposition BB bond money, the wire-mesh grilles were approved by the school board as a way of stopping theft and vandalism, even though such problems have diminished sharply in the past year.
I'm concerned about the safety of all teachers and students,'' said Principal Fran Ramirez, who had the grilles removed from Chatsworth High School bungalows.
After receiving complaints about the grilles at two campuses, school board member Valerie Fields, who chairs the district's safety committee, said she would call an emergency meeting to investigate whether they could be equipped with safety latches that would allow them to be opened in the event of a fire or other emergency.
