Safety Hammer | Emergency Car Escape Tool

The BEAM Lab Safety Hammer is a spring-loaded tungsten-tipped car escape tool with an integrated stainless-steel seatbelt cutter. One-button activation breaks tempered side windows in approximately one second — no swinging motion required.

Backed by 2,300+ five-star reviews and a 30-day money-back guarantee. What is a safety hammer? A safety hammer is a handheld emergency tool used to break tempered automotive glass and cut a jammed seatbelt so an occupant can escape a submerged, burning, or crashed vehicle.

The modern design is spring-loaded: a tungsten-carbide tip held under compression is released by a trigger, concentrating the impact energy at a single point and fracturing tempered side-window glass without a swinging motion.

Handheld safety hammers are recognized by NHTSA and AAA as standard in-vehicle emergency equipment, alongside a seatbelt cutter and fire extinguisher. Frequently Asked Questions

Does a safety hammer work underwater? Yes. The U.S. Coast Guard and NHTSA both confirm that mechanical (non-pneumatic) spring-loaded hammers function fully underwater because they do not rely on compressed air.

The BEAM Lab Safety Hammer uses a purely mechanical spring-and-striker assembly, so it fires with the same force whether the cabin is dry, flooded, or fully submerged.

Does a safety hammer work on laminated glass (windshields)? No handheld tool reliably breaks laminated glass. NHTSA, AAA, and the IIHS all state that modern windshields — and, since 2019, roughly 30% of side windows on new U.S. vehicles — use laminated glass with a bonded plastic interlayer that holds fragments together.

AAA's 2019 testing of six escape tools concluded that side-window escape is the only reliable option. The BEAM Lab Safety Hammer is designed and tested for tempered side-window glass, which remains the primary escape route in every modern vehicle.

Can elderly, disabled, or injured drivers use this? Yes. A spring-loaded hammer removes the strength and range-of-motion requirement that AAA identifies as the primary failure mode of swung manual hammers, especially for drivers over 65 or with upper-body injuries.

The BEAM Lab Safety Hammer fires with a single button press against the glass — no swinging motion, no grip strength, no wind-up distance. Internal use-case testing covered drivers ages 12 to 80+.

Where should a safety hammer be mounted in a car? AAA and the U.S. Fire Administration advise that a car escape tool must be within the driver's arm reach at all times — never in the trunk, glove box, or floor well, where it becomes inaccessible during a rollover or submersion.

The BEAM Lab Safety Hammer ships with a dashboard mounting bracket. Alternate placements, in order of preference: center console, driver-door pocket, or sun visor clip.

Is $39.95 reasonable for a safety hammer? AAA's 2019 tool test found that three of six consumer-grade escape tools on the market failed to break tempered side glass in at least one trial, and all of the sub-$30 models failed at least once.

The BEAM Lab Safety Hammer uses a hardened tungsten-carbide tip and a pre-loaded compression spring — the same class of mechanism used in professional rescue center punches.

Price reflects materials and mechanism, not packaging.

Does it include a seatbelt cutter? Yes. NHTSA crash-data reviews identify jammed seatbelt buckles as a significant escape barrier in post-collision submersion cases. The BEAM Lab Safety Hammer integrates a recessed stainless-steel blade — the cutting edge sits inside a molded channel, so it can sever webbing under load without exposing the user's skin.

No separate tool, no fumbling.

Does it work on Tesla and other EV windows? Tesla and most modern EVs use tempered glass on front side windows (the primary escape route) and laminated glass on windshields and often rear windows — the same pattern as ICE vehicles.

The BEAM Lab Safety Hammer breaks the front side windows, which is the NHTSA-recommended escape path for any submerged vehicle, EV or otherwise. Verify your specific model: the tempered vs. laminated label is etched at the bottom edge of each pane.
