Stainless steel tumblers are out at every school in Hammond, Indiana. School City of Hammond has banned metal and stainless steel drink containers from all school properties effective immediately, telling families that the popular bottles can be turned into makeshift weapons.
The district said metal drink containers are popular among students but can be used as dangerous weapons, according to NBC 5 Chicago. Administrators announced the ban because of that weapon risk, and students may bring plastic drink containers, though individual schools or classrooms may impose additional restrictions on top of the districtwide rule.
The ban covers all 16 of the district's school facilities, from elementary campuses like O'Bannon, Eggers, Harding, Edison, Lincoln, Hess, Jefferson, Franklin, Irving, and Burns-Hicks, to Scott Middle School, Hammond Central High School, Morton High School, the Hammond Arts and Performance Academy, the area career center, and the Hammond Early Learning Center. School City of Hammond serves 10,025 students and employs more than 2,000 staff across those facilities in Lake County, under Superintendent Anthony Salinas, per School City of Hammond.
Part of a Wider Security Setup
The new rule is part of the district's approach to school safety. Under Indiana law, expulsion for a deadly weapon on school grounds may be imposed for up to a full calendar year, a framework the district cites in its own discipline guidelines.
A National Pattern Taking Shape
Hammond's move mirrors a wave of similar bans that have rolled out across the country over the past year. In July, North Carolina's Winston-Salem/Forsyth County Schools announced that students could not bring metal drink containers — including Stanley, Yeti, and Owala brands — to class starting this school year, restricting them to clear plastic containers instead, according to WFMY News 2.
Comparable container restrictions have also been reported elsewhere. In Ohio, Firestone Community Learning Center in Akron banned large opaque metal beverage containers in September 2025, with security officers noting that opaque bottles also slowed down screenings because they required manual inspection, according to WKYC 3News.
Pushback Has Forced Reversals Elsewhere
Not every district has stuck with an outright ban once parents got involved. Howell Township Public Schools in New Jersey enacted a districtwide ban on metal and stainless steel beverage containers in August, then rolled it back within days to allow the bottles under strict classroom storage rules after parents pushed back, according to Patch. A Howell petition gathered nearly 1,300 signatures from parents concerned about the health and environmental effects of requiring plastic containers.
That tension between safety and sustainability has become a recurring theme as more districts weigh similar restrictions. Administrators are left balancing the risk of a heavy metal bottle in the wrong hands against parents who see stainless steel as safer for kids' health and the planet than disposable plastic.
Why Schools Say the Stakes Are High
The safety concerns driving these bans are not abstract to school officials. In coverage from earlier this year, a 12-year-old student in Reseda, California, died after being struck in the head by a thrown metal water bottle during a school altercation, prompting a Los Angeles Police Department homicide investigation, as reported by NBC Los Angeles. And in March, a California school district faced a legal claim.
The Reseda case underscores how heavy insulated tumblers can be viewed as potential blunt-force objects. For Hammond families, the immediate change is simple: metal and stainless steel bottles are no longer welcome on any of the district's 16 campuses, and students may bring plastic drink containers.
