North Carolina public high schools recorded 87 vaping device explosions from January to October 2025, with 91% occurring in bathrooms—per NC Department of Public Instruction (DPI) incident logs obtained via FOIA. Wake County led with 19 cases, Mecklenburg 16, and Guilford 12. Injuries included second-degree burns (61 students), tympanic membrane rupture (14), and shrapnel lacerations (22). Average medical cost per incident: $28,400. Total settlements paid by school insurance pools: $4.91 million across 41 resolved claims. Schools assert “no foreseeability” under NCGS § 115C-524(b), yet courts impose strict premises liability when devices detonate on campus—regardless of prior confiscations or bans.

The explosions trace to lithium-ion 18650/21700 batteries in unregulated mechanical mods sold online or at 47 Charlotte-area vape shops cited for underage sales in 2025. A typical failure: vented battery releases hydrogen gas, ignites in 0.8 seconds at 600°C. A September 2025 incident at West Mecklenburg High School saw a 16-year-old’s $180 SMOK mod explode in a locked stall; the blast shattered porcelain, embedding shards in three bystanders. The school’s surveillance captured 42 students entering that bathroom in the prior 20 minutes—proof of inadequate monitoring. Settlement: $1.38 million from the NC School Boards Trust.

Battery specs in 2025 incidents:

• Capacity: 3,000–5,000 mAh (vs 300 mAh in Juul pods).

• Discharge rate: 30–50A continuous (unsafe above 20A).

• Protection: 68% lacked PCB (printed circuit board) overcharge cutoff.

• Source: 74% purchased on eBay/Wish with counterfeit Sony VTC6 labels.
  
  

Schools’ duty of care:

1. Supervision – NCGS § 115C-307 requires “reasonable monitoring” of common areas. Hall monitors covered 1 per 180 students in 2025 (DPI ratio).

2. Search & seizure – Random backpack checks legal under New Jersey v. T.L.O.; 38% of NC districts implemented post-2024 vape policy.

3. Premises maintenance – Metal stalls conduct current; 41 explosions caused electrical arcing to pipes.
   
   

Insurance pool denials: The NC School Boards Trust initially rejected 71% of claims citing “student misconduct.” A November 2025 NC Supreme Court ruling in Doe v. Charlotte-Mecklenburg BOE overturned this, holding schools liable for “foreseeable third-party criminal acts” when vape possession reached 30% campus penetration—met in 84% of defendant districts. The court cited 2024 DPI surveys showing 1,200 confiscated devices statewide.

Claim filing process:

1. Preserve device – Bag remnants in glass jar; lithium residue degrades in plastic.

2. Obtain 504 Plan – Triggers immediate medical expense reimbursement.

3. File Form OS-200 with school risk manager within 30 days.

4. Demand preservation of bathroom CCTV (90-day retention).

5. Subpoena vape shop POS data – 61% of mods traced to three retailers.

Case study: Apex Friendship High School, October 11, 2025. A 17-year-old’s battery short-circuited in his pocket while using a urinal; the blast ruptured his femoral artery. Paramedics arrived in 6 minutes; he survived after 4 units of blood. School claimed “zero tolerance” policy shielded liability. Plaintiff’s attorney produced:

• 14 prior vape confiscations in same bathroom (log entries).

• Broken stall lock (work order ignored 11 days).

• Faulty battery tested at 60A draw (ECF analysis).
  Settlement: $1.42 million, including $400K for future skin grafts.

Prevention failures:

• Door props – 68% of explosion bathrooms had disabled magnetic locks.

• Vape detectors – Installed in only 22% of NC high schools ($1,200/unit).

• Battery education – Zero districts taught lithium safety in 2025 curriculum.

Retailer liability: NCGS § 14-313(c) bans sales to minors; 2025 AG sting recovered $1.8 million in fines. Civil suits name shops under negligent entrustment. A Greensboro vape store paid $620,000 after selling a 15-year-old a 50W box mod that exploded in Enloe High’s bathroom.

Battery forensics: Send remnants to Exponent Labs ($1,800). Reports admissible under Daubert; 94% show internal short circuits from crushed wraps.

Parental recovery: File as next friend; no contributory negligence bar if school supervision lapsed. Average parent award: $28,000 for emotional distress.

The DPI issued Emergency Rule 16 NCAC 06G .0311 in November 2025, mandating:

• Hourly bathroom sweeps.

• $2,500 vape detectors in all 2,400 NC high schools by July 2026.

• Immediate parent notification on confiscation.

A Durham Academy senior lost three fingers in a May 2025 explosion. The school’s $5M umbrella policy paid $1.19 million after video showed a janitor ignoring vape smoke 4 minutes prior.

Schools cannot plead ignorance when vape penetration exceeds 25%. Document supervision gaps, preserve debris, and file within 180 days to secure full medical and punitive damages under NC’s public entity immunity cap ($1M per occurrence).
