Safeglass VS Glass
Traditionally,
normal float glass has been used in 'break glass' panels making them difficult
to use and subjecting passengers and staff to a high risk of injury.
Safeglass® significantly reduces this risk of injury since it is safe to
break, forming pieces that do not hold an edge.
The exposure to the risk of injury is increasing with the incidence of vandalism,
creating debris that could injure other passengers as well as cleaning staff.
Safeglass® will not harm other passengers and can be safely cleared away.
It cannot be used as a harmful weapon.
Safeglass® VS Sugar (theatrical) Glass
Theatrical
glass used in the film industry has been used on rolling stock and does address
the safety issues posed by glass. The hand made process, however, means that
clarity and consistency are often low. The material is made from a resin which
is very weak resulting in a high number of breakages during fitting and whilst
in use. It has also been criticised for producing a messy powder that can block
door runners.
Safeglass® is produced to a high, machine finished quality and is much stronger than sugar glass - the annual requirement of TOCs who have changed to Safeglass® has substantially decreased.
Safeglass® VS Toughened Glass
Toughened
glass is sometimes used for break-glass. The glass breaks into cubes that are
safer than the shards produced by normal float glass.
Toughened glass is extremely strong and is very difficult to break, making the
emergency equipment housed virtually inaccessible and therefore useless.
Safeglass® is produced to a strength that most people can break.
