Glass management
• All glass must be managed at every RTA
• Once managed, vehicle glazing cannot cause problems such as entering open wounds or breaking in an unexpected or uncontrolled manner.

Types of glazing
• Safety glass (laminated)
• Tempered glass (toughened)
• Perspex (plastic).

Management methods
Three main approaches;
• Removal (can prove difficult)
• Controlled breaking (best method)
• Cutting (bonded screens).

Laminated glass
• Usually bonded onto shell
• Requires special removal techniques if bonded
• May still use rubber extrusion fittings
• Glass dust may present a hazard for rescuers and casualty.

Laminated glass
• Found in more modern vehicles
• Usually the windscreen or rear screen
• Consists of a plastic film in between two layers of glass
• Will break into long slivers of glass.

Toughened glass
• Usually side and rear windows
• Windscreens in older vehicles
• Shatters into thousands of pieces
• May remain in frame giving a frosted appearance.

• Glass
• Bodywork
• Locking strip.

Controlled breaking• Wind down any available windows,
consider battery disconnection
• Leave 50mm approx showing and cover
• Ensure casualty is well protected
• Initially break glazing furthest from casualty
• Remove any glass from immediate area.
