| What is Ozone
Layer? |
| Ozone is nothing you can
see. It is a naturally occurring gas found in the earth's
atmosphere. At the outer edge of the atmosphere, there is a thin
layer of ozone gas that is critical to life on earth. It is the
stratospheric ozone layer. This layer protects us from the harmful
rays of the sun. If it weren't for the ozone layer, we'd get wicked
sunburns, wreck our eyes, and kill our plants. |
|
| What Causes Reductions
of Ozone Layer? |
| When certain chemicals used
on earth escape into the atmosphere, they are broken down by solar
radiation and release chlorine and bromine atoms which, in a chain
reaction, destroy ozone molecules. This reaction occurs more
frequently than natural ozone replenishment, resulting in a thinning
of the ozone layer. |
|
| What are
Halons? |
| They are low-toxicity,
chemically stable compounds that have been used for fire and
explosion suppression throughout this century. Today, Halon 1211 (a
liquid streaming agent) is used mainly in hand-held fire
extinguishers and Halon 1301 (a gaseous agent) is used mainly in
total flooding systems. These halons have proven to be extremely
effective fire suppressants, which are clean (leave no residue) and
remarkably safe for human exposure. |
| A compound's ability to
destroy ozone depends on many factors, including the amount of
chlorine and/or bromine that it contains. To aid them in comparing
compounds, scientists have developed a relative scale called the
ozone depletion potential (ODP). Common refrigerants have been
assigned the value 1 as a reference. Halon 1301 has the value
between 10 and 16, meaning it has 10-16 times more potential for
destroying the ozone layer. |

| Halon
Recycle |
| Unlike aluminum cans or
newspapers, once halon is released it is virtually impossible to
recover. If halon is still contained in cylinders retired from
service or if a container is leaking, the halon can be recovered for
reuse. In fact, some halon distributors and users have been doing
this for many years, long before halon emissions were identified as
an environmental problem. |
| Current legislation
prohibits the production or importation of new Halon 1211, 1301, or
2402. Recycled halon is now the only source of supply. Many
organizations that continue to rely on halon systems for fire
protection have instituted programs to identify their most critical
needs. Halons that can be removed from non-critical or obsolete
facilities are then recovered for use in more critical
applications. |
|
| Hong Kong
Halons |
| Merito Technical Services
Ltd. has obtained official License from the Hong Kong Government to
recharge and recycle different fire suppression substances including
Halons. There are mainly 2 ways for you to remove your Halons in
Hong Kong. |
| 1. Merito collect your
Halons and transfer them to Hong Kong Government's chemical lab for
destruction. |
| 2. Merito collect your
Halons and transfer them to US Recycling company to recycle those
Halons to critical users. |
| We also offer a whole
package for your Halon system replacement with alternative system.
Contact us today
for your Halon replacement to prevent unnecessary
release. |
WE ARE ALL IN THIS TOGETHER!
