Which is correct regarding forcibly entry through railcar Lexan windows?

• A. Lexan is designed to fracture into many small pieces when broken
• B. remove the entire pane or cut through it with a power saw
• C. tempered glass is best breached with a power saw
• D. tempered glass is really a polycarbonate

Answer: (B)

Forcibly entering through Lexan windows on railcars involves specific considerations due to the material properties of Lexan, which is a type of polycarbonate plastic known for its strength and resilience. Option B is correct because removing the entire Lexan pane or cutting through it with a power saw are effective methods for gaining access. Lexan is engineered to be shatter-resistant, which makes it difficult to break using traditional methods like blunt force. Therefore, using a power saw allows responders to create an opening safely and effectively without the risk of the material shattering into small, hazardous pieces, which can occur with glass. Additionally, cutting the pane allows for a cleaner entry point when accessing the interior of the railcar. Understanding the characteristics of Lexan is crucial for first responders and rescue technicians, as it differs significantly from other materials like tempered glass, which may require different approaches for emergency entry.
