Urinating in a bucket is a tough go for students when a school is in lockdown because of a dangerous situation, as El Camino Real and Gardena high schools experienced this week in the wake of shootings.

Although students described using a trash can or empty paper cup in which to urinate during Wednesday's lockdown at El Camino Real, it turns out the bucket is part of a "lockdown kit" that is supposed to be in every Los Angeles Unified School District classroom.

The lockdown kit includes a 5-gallon bucket or pail with a removable lid “solely for the purpose of this kind of situation,” said district spokesman Robert Alaniz.

He said the kits should have been in every classroom at both schools, and it appeared some students made use of them at El Camino Real High in Woodland Hills, where a school police officer was wounded off campus, and at Gardena High, where two students were injured Tuesday when a gun accidentally discharged in class.

Law enforcement-ordered lockdowns kept students in classrooms and gyms for hours.
