Controlling the use of emergency exits is vital in most
organisations. For retailers it is important that evacuation doors can’t bypass
the main doorways to be used by shoplifters and thieves to avoid the checkout
security sensors. For schools, colleges and hospitals it prevents the use of
fire exits to sneak off-site, smoke or even pinch equipment. Even more
important than these issues is the safeguarding of those legally responsible
for the health and safety of the building occupants and its users.
Obvious as it may seem, emergency exits only work if they allow
unimpeded evacuation in an emergency. Therefore a procedure to check that exit
doors and routes are clear is paramount. Not just a procedure but a documented
procedure that logs each and every test opening and identifies who undertook
that important safety check and when?
It is to this end Unisto created the Security Seal &Sash solution for push bar type doors and Security Label for single doors. Each
uniquely numbered seal can be easily broken requiring a force of less than 6kgf
to break and not cause any obstruction. On a regular basis; daily, weekly or
monthly (according to regulation) the seal is broken, the sash removed and the
door opened and an inspection of the evacuation route made to ensure that it is
clear. The sash is then resealed on the push bar ready for the next cycle. The
inspection is logged with date, time, broken seal number, replacement seal
number and initials; providing a full audit trail that can be inspected by a Health
and Safety Manager or a Fire Officer.
Our high-vis, reflective and reusable sashes are also
designed to be easy to break in an emergency but not for safety inspections, so
they can last for many cycles, making the system cost-effective. The sash is
designed with three perforated seal eyelets at either end, if one eyelet breaks
the next one can be used to seal. The use of reflective material highlights the
exit in low light conditions if a flashlight is shined on it, as an additional
safety benefit.
It is often interesting to see how big retailers, exhibition
centres and public buildings manage their exit doors. You can see high
break-strength seals used where great force would be needed to break the seal to
escape and others where multiple security seals are linked together in a daisy
chain effect; although which number gets recorded in the audit log is anyone’s
guess! We were once even involved in a tender that specified a steel cable seal
for fire doors and with a break strength of circa 1,000 kgf no-one would have
made it out alive if that had ended up being used.
The whole sealing and safety process is to protect those who
have responsibility for building safety to show there is a procedure; it is
followed, checked and audited to prevent a disaster. However should a disaster
befall the building the health and safety team can demonstrate their care and
competence with an auditable checking system that the authorities can inspect.
For those with legal liability, one does not simply need to
be competent; one needs to be able to prove it and if necessary before a court
of law.
