Engineering / Compliance FAQ

Which standard or standards do these devices comply with?

None. There are no standards for break glass devices anywhere in the world. safeTpunch have set our own independently tested minimum performance criteria.

Do break glass hammers have any certifications?

No, there are no certifications or minimum performance standards to measure a hammer by.

 

How do we accept your products as compliant to regulations?

It is compliant if it performs the same function as the existing alternative and conforms to the relevant regulations for emergency exits.

Which standards are break glass emergency exits compliant to?

Glass must be toughened to E43R, BS857 or equivalent standard. The size of the emergency exit aperture is governed by local road transport regulations.

Does the device comply with public transport emergency exit regulations?

safeTpunch devices comply to the requirements of UNECE R107 (Accepted almost universally), ADR 44 (Australia and New Zealand, basically a copy of R107) and FMVSS217 (United States of America)

 

Do safeTpunch devices have any certifications?

Certifications are only awarded if the device in question complies with an internationally recognised standard. In the case of break glass tools or devices, there are none.

Are the safeTpunch products verified for functionality by the factory?

The parts are internally tested 1/100. Reports and devices are kept for 1 year before recycling and reconditioning.

Do you have a Quality Control certification?

We have ISO 9001:2008 Quality Control Certification audited by TUV Rheinland in German.

 

Have you done a DFMEA on your products?

Design Failure Modes and Effects Analysis studies are completed with every component part, sub assembly and fully assembled device.

Do you run FRACAS?

Yes. safeTpunch has our own manual but robust Failure Reporting and Corrective Action System.

 

Don't you need professional FRACAS software?

safeTpunch have a relatively small number of components and all the parts are assembled by hand so the chance of Non-Conforming Products (NCP) being shipped is extremely small.

Can we change any designs to suit our purpose?

Yes but only if the proposed design alteration withstands our DFMEA scrutiny, falls within the scope of our ISO 9001:2008 and improves the cost and quality of our products.

 

Can we print our own stickers?

Under our Warranties, our ISO and our liability Insurances, we have to supply instructions sticker with every safeTpunch. Our design elements and iconography are copyrighted and may not be used without licensing.

Can we white-label the product?

No. safeTpunch products are identified by Trademark, Design and Unique Serial Number.

Can we Co-Brand?

Yes. Under the right circumstances we can allow for other brand logos to share the customer-facing portion of some of the products only.

 

What is your warranty period?

Our warranty is indefinite as it stands, but we will apply the same warranty period as the vehicle manufacturer offers.

Can we manufacture these parts under license?

Yes. We have structures in place for licensed manufacture.

Device Performance FAQ

Can you comment on the purpose of the STP40D?

The STP40D is very good at standard and heavy duty or non-standard roles. i.e. glass of indeterminate thickness and curved toughened glass. STP40D punches are also effective but not guaranteed on double glass units up to 28mm. Non-standard applications must be tested and approved by the client.

Can safeTpunch be used in exterior applications?

safeTpunch devices are made out of non-corrosive and environmentally stable materials, except for the anodising, which fades in sunlight over time. We replace the anodised finish with red Gunkote, laser etched as normal.

 

What is the thickest glass the devices are capable of breaking?

Wintech Engineering have independently tested the STP40FA on 6mm BS857 glass and we have performed successful informal tests on 8mm BS857 toughened glass.

Can the devices work when fully submerged?

Yes. safeTpunch devices are all designed to be used fully submerged if necessary.

How can I see the safeTpunch device in the dark?

safeTpunch have a production option for photo-luminescent instructions stickers.

Are safeTpunch accessible to the visually impaired?

safeTpunch have a production option for braille embossed instructions and seat-back direction to the nearest exit location.

What if the safeTpunch device doesn't work first time?

safeTpunch devices are designed to deliver each consecutive blow to the same place on the toughened glass, so strike multiple times if necessary.

Can I re-use the safeTpunch?

safeTpunch impact tips are many times harder than toughened glass and can be re-used or recycled many times before decommissioned by us.

Can I buy spare parts?

Yes. N and D-series devices can be reconditioned and refitted with the spare tape and safety tags. F-series devices will need to be returned to us for reconditioning. We will replace any returned safeTpunch free of charge.

How can I verify the N or D-type safeTpunch are operable?

If the red button and safety tag can be turned freely by hand, the device is operable. Check General Maintenance manual STP-GM.

How do I verify the F-type safeTpunch are operable?

Remove the safety tag and press around the edge of the button, if the button depresses, the device is operable. Replace or refit the safety tag. Check General Maintenance manual STP-GM.

 

How do I repair a safeTpunch with a fouled action?

This varies from model to model, so please check General Maintenance manual STP-GM.

End User FAQ

Can I install a safeTpunch on the windshield?

No. A windshield is made of laminated glass which is designed to be as impact and penetration resistant as possible.

Will the safeTpunch work on laminated glass?

No. Laminated glass is designed to be as impact and penetration resistant as possible.

 

Will a safeTpunch work on non-toughened annealed or float glass?

No, safeTpunch work exclusively toughened glass that conforms to standards like BS857 or E43R.

Will safeTpunch work on toughened glass that have anti-scratch film fitted?

Yes. safeTpunch impact tips will penetrate anti-scratch films and break the glass beneath.

Will safeTpunch work on glass fitted with anti-graffiti film?

Yes, but as anti-graffiti film chemically “shrugs off” the inks or dyes in markers and spray paint, it may have the same effect on the safeTpunch and sticker adhesives.
Fix: We suggest removing the film under the safeTpunch and sticker assembly, exposing the glass for the adhesives to be reliable.

Will safeTpunch work on glass fitted with anti-vandal film?

Anti-vandal film is a combination of anti-scratch and anti-graffiti film and will probably shrug off the adhesives on the safeTpunch and the sticker.
Fix: We suggest removing the film under the safeTpunch and Sticker assembly, exposing the glass for the adhesives to be reliable.

Is vandalism a concern?

No, safeTpunch is built to withstand a lot of abuse. If a part is damaged beyond usefulness, we will replace the damaged part if it’s returned to us.

Is accidental activation a concern?

safeTpunch are supplied with a safety tag that must be removed before the device is armed. Then it takes a deliberate strike to break the glass.

Is activation by mis-adventure a concern?

We have had no reports of improper use to date.

Is theft a concern?

safeTpunch is extremely difficult to remove without tools if properly installed and allowed to cure for 72 hours.

How do I know if the glass is toughened or not?

Check the edges are completely smooth and rounded, find the glass standard mark sandblasted close to the edge or view the glass through a polarised lens, looking for a dotted pattern caused by the toughening process.

 

Can toughened glass cause injury?

Toughened glass is designed to shatter into small cubes the size at the glass’ thickness and therefore unable to cause harm.

Can my toddler or child activate a safeTpunch?

safeTpunch will only work when sufficient force is applied. The minimum strike force required is that of an average 12 year old person.

How do you communicate the instructions for use with visually impaired passengers?

We offer braille embossed instructions for use and seat-back communication of the location of the emergency exits.

 

What do you do about new language requirements?

If a translation is approved and supplied by the client, we will create the artwork; require approval from client and supply as requested. Low volume print runs can be more expensive.

Can you create specialised stickers?

Yes, with an accurate client brief, we will create the artwork; acquire approval from client and supply as requested. Low volume print runs can be more expensive.

How often do the stickers need replacing?

We recommend replacing them every two years or when they are damaged physically or by the sun.
