The O In The Ozone

The hole in the ozone is something I grew up knowing about. I knew CFCs were bad for the environment and still are, but somehow in amongst all the other things we’re doing that are damaging the world, they’ve perhaps got a bit lost.  Are we still using these damaging products and is that hole getting bigger?

In 1987, the Montreal Protocol was signed  to help reduce the use of substances that deplete the ozone layer and to celebrate, in 1994 the UN General Assembly set aside 16th September as the International Day for the Preservation of the Ozone Layer.

The Montreal protocol, so far, has been very successful and the hole in the ozone layer is expected to have recovered by approximately 2050. It’s great to have a bit of good news, isn’t it?

In recognition of this achievement, I’m going to share with you some of the things that have contributed to O in our ozone, in the first place, so that we can continue to avoid them.

  • CFCs used in aerosols, sterilants and some foams
  • Halon, usd in portable fire extinguishers
  • HCFCs
  • Methyl Bromide, an agricultural fumigant
  • CFCs used in solvents, coatings and adhesives

All of the above are gradually being phased out under the Montreal Protocol and it’s important that we as consumers, support this, don’t forget about the hole in our ozone and choose products without any of the above in them.
