These are the questions people have been asking. At Sabie Poles, we are more than happy to give you the answers. We will discuss everything from the safety, health effects, sale uses, and disposal of CCA Treated Wood in South Africa in this post.
What is CCA Treated Timber?
In order for wood to last in harsh weather conditions and be resistant to insects, it needs to be treated with various chemicals that will allow the wood to have a longer life expectancy. In order to preserve the wood it get’s a thorough high-pressure treatment with CCA (chromated copper arsenate). If you’d like to know more about the process, we’ve dedicated a section in this blog post to explain the whole treatment process.
Whenever the topic of wood treatment arises, the initial question that invariably emerges is, “How long can we expect CCA-treated wood to last? Is it truly a worthwhile investment?”

Precautions when using CCA Treated Timber:
- Wear a mask in order to avoid breathing treated lumber dust
When you are working with CCA Treated Wood, it is always necessary that everyone in close proximity should wear a mask. This applies to everything from sawing and drilling to cutting the treated timber. This not only applies to treated timber, but also to any type of untreated timber.
Even when working with untreated timber, the dust from the wood can result in serious health effects. This is due to the fine dust particles that make their way into your lungs.
- Wear Gloves to prevent pressure treated wood splinter infection
When you’re working with any type of wood, treated or untreated, it is wise to use gloves to avoid cuts and splinters. When you are working with treated timber, it becomes more important. A simple splinter from pressure treated timber might result in a small infection. If you are unable to get the splinter out and the pain is persistent, we recommend you visit a doctor for the removal.

Sometimes it is possible for a person to be allergic to a certain element in the treated timber. Unfortunately, there is not much a person can do regarding these allergies. Any over the counter allergy medicine should clear up any symptoms you might present with when being around CCA Treated timber.

How to properly dispose of CCA Treated Timber
“CCA treated timber must only be used as intended, and therefore when it reaches the end of its
usable life, i.e. structures are broken down, it is recommended that it be re-used as in other timber
applications when possible. If no re-use applications are available it should be disposed of at either
a registered landfill site or waste disposal site, from where it will be disposed of to a registered
CCA treated timber waste, i.e. demolition waste and/or off-cuts must never be burned for disposal,
heating or cooking purposes as it releases the fixed components which contain toxic and harmful
substances. The aforementioned disposal methods apply.” – SAWPA
If you are unsure of a licensed landfill close to you, you can visit SAWIC to look for a registered landfill near you.
In general, the health hazards are minimal to both humans and the environment. It is safe to use for construction indoor and outdoor.
