Is Wood Dust Risky to Health?

  • Nasal Cancer
  • Occupational Asthma
  • Lung Cancer
  • Nasal Sores 

sinuses and nasal cavity

Sadly cancers are associated with the inhalation of wood dust. Wood dust inhalation contributes to paranasal 

Is wood dust a carcinogen?

Yes, wood dust is now considered a Group I carcinogen. A carcinogen affects our DNA causing mutations. Carcinogens held within wood dust can cause lung cancer.

Wood Dust can cause cancer?

Wood dust is now considered a Group I carcinogen. A carcinogen affects our DNA causing mutations. Carcinogens held within wood dust can cause lung cancer.

Hardwoods is considered the most dangerous compared to softwoods.

What is wood dust?

Wood dust is the by-product of the woodwork. Wood dust is either fine or coarse depending on how it has been produced.

What is the most dangerous wood dust?

Any wood dust is dangerous but some wood dusts are very toxic in larger quantities. At the bottom of this Blog is a list of timbers and their potential risks to health.

Preventing inhalation of wood dust?

A common-sense approach to the control of wood dust. 

Make a dust control method statement. Why? You may ask but making a ‘Method Statement’ often enlightens you into the bad practices. This can heighten your knowledge of the risks and simple changes that could help.

How do I stop inhaling dust?

To be honest, I admit it is probably a tall order but you can certainly reduce your risk of wood dust inhalation. 

We have to remember that wood dust will become airborne and we are at risk of breathing it in.cyclonic dust extraction for the workshop

You can reduce your inhalation of wood dust. 

By making use of your tools dust extraction and a good dust extraction vacuum you can drastically reduce inhalation of wood dust.

You must be sure that your protection actually protects!

For any filtered protection you need to refer to the specification of the filter. The reason for this is that some timbers produce finer dust particles. For instance I fine that the dust from sanding walnut or cherry has more chance of getting past your filters that Oak or Pine.

A dust mask is imperative when all else fails

There are many situations where a dust mask has to be worn. Some woodworking practices have no possible way to collect dust efficiently. Hand sanding is a prime example of poor dust collection. 

But dust masks are uncomfortable!

Yes this can be true and a pain when you have to wear all day. Simple paper masks are a compromise between a leaky mask and nothing at all. You could wear a 3M silicone mask with replacable cartridges but i find these heavy and make your skin itch.

Neoprene dust masks are more comfotable than standard dust masks. These masks carry a carbon filter which healps to filter toxins.

Woodworking and dust control solutions?

Here I will try to give you some idea of the methods of dust control for each woodworking practice. Like I said before that it is best to control dust before it goes airbourne. There are many dust extractor solutions but they all cost some money but you could just make some behavioural changes. 

A dust control system can be a per machine extraction vac or a central vac system.

Dust extraction with woodworking machines best practices

spindle molder dust extractor

Modern woodworking machines have made huge advancements in dust collection. Virtually all machines have some form of dust control. Health and safety has played a huge part in enforcing the addition of dust extraction ports to our woodworking machines.

How good is dust extraction on woodworking machines?

Sorry to tell you that you will not be able to completely wipe out the inhalation of wood dust. It is always better to collect the wood dust at source but you have to be aware that some dust will escape into the atmosphere. Because of this fact, you must take secondary precautions such as the comfy dust mask!

How to switch on extraction vac?

A problem I have found with dust extraction is that remembering to turn on the vac when starting a machine. You have a few options but the best solution is an automatic load sensing switch. So when you turn on a machine the switch senses a voltage drop and turns-on the tool extraction vac. You can buy these switches as a seperate unit oe some tool vacs have one installed. It ios posible to make a load sensing switch with an Arduino device.

How do we control dust when hand sanding?dust extraction chip bags

Using machines that have dust extraction ports connected to an extraction vac is preferable. When sanding by hand with a sanding block your dust collection options are limited to impossible. Where a good cartridge dust mask or a ‘Trend Airshield’ helmet. I vacuum table is a good investment when hand sanding.

Do dust extraction vacuums work?

Good dust extraction vacuums work well but not 100% efficient. Choosing a good wood dust extraction unit is not simply just a vacuum cleaner with an appropriate connection tool. The filtration systems differ greatly. The pleated paper dust filters that are found in most workshop-style vacuums do not have enough surface area to be effective.

Cyclonic Dust Deputy

Dust deputy is a brand of cyclonic dust collection afterthought retrofits. These are effective and almost prevents any dust getting back to the atmosphere. You can use almost any shop vac with a dust deputy. 

Working with old reclaimed materials

We tend to think that wood is a natural material and we can be forgiven for that.  The one thing we must remember is that any natural material can be contaminated. Not just contaminated but also it can contain some  carcinogenic compounds.

Does new wood contains contaminants?

We have to remember that timber has a history and that history can contain artefacts.  These artefacts can be in the form of tiny foreign particles of toxins. My shutter building business is located in France in the Rural countryside.  The countryside has wildlife and some of that wildlife consists of rats and as you would expect that will run-walk and play on seasoning timber.  Some processed timber is left waiting for its final useful purpose. During this dormant time, it is likely that vermin and other toxins could fall upon the wood. 

Old used wood has history too

Like me would also have a history.  There’s history can be a variety of different situations that it has been exposed to.  Painted wood of modern times is coated with paint that is not toxic. If the timber is being repurposed after it has been stored post Reclamation it is possible that there are some other toxins present.  paint today is considered safe but a few decades ago paint contained lead. 

Does wood contain lead?

Paint containing lead is highly toxic.  As an example, my wife’s cousin died as a baby because he was chewing on a windowsill coated in toxic lead paint.  a sad story. 

Today we are more careful we realised that some materials used in the past are incompatible with healthy living in the future. 

Upcycling can be dangerous

If working on old houses or Barns etc you should do a survey in the form of a risk assessment.  Without this risk assessment, you were taking unnecessary risks.

If you have to work with materials such as wood that has been treated with paint or other chemicals take precautions.  these precautions can be in the form of a dust mask or some form of respiratory equipment.

Simple detergents used in cleaning your home can soak into wood and drys into a residue which after multiple cleaning sessions over many years can leave a coctail of chemistry. This is probably safe while the old wood is left alone. Once you start sanding the timber and make sanding dust then these chemicals become airbourne.

Our lungs perform like a filter

You can tell yourself that all will be ok because my upper respiratory system can filter out particles. this is true to a point but our upper respiratory system can only filter out larger particles. You are a risk of inhaling small particles into your lungs contaminating your lungs and potentially your bloodstream.

The result of inhaling small particle toxins is reduced lung capacity.  The scarring to the pleural layers is irreversible. The pleural layers are within your lungs. 

Indirectly we are a risk of asbestosis

The end result of inhaling toxic long damaging particles is very similar to asbestosis.

Asbestosis is the scarring of the pleural layers within our lungs.  this is caused by the fibres of dangerous asbestos having double barbs.  Asbestosis is caused by asbestos which has these barbs scarring the pleural layers as we try to exhale the irritant fibres. Asbestosis is irreversible and in some cases, you will have to have oxygen provided by a cylinder. In time you’ll find it virtually impossible to breathe. Be careful take precaution do not inhale this dust. 

Plastic homes are toxic

In the modern world, where are we fine Homes with plastic coated particle board?
The risk of inhalation of toxins is very high. While these materials are in their solid-state they are relativity safe. But in this modern world where we are told to recycle and reuse or even upcycle. We must take precaution and understand the material we are working with.  

Avoid modern materials

A modern material such as Conti Board, chipboard covered in a resin film. Is a carrier of two potential toxins that first spring to mind.  One is resin plastics and the other is the glue that bonds the particles together under high compression. 

Tanalised timber contains arsenic?

We have to take care of also for other chemical treatments. Wood treatments such as tanalised timber contain arsenic. Arsenic is actually a natural chemical and can be found in cherry stones. In the early 2000s, the arsenic component of tanalisation was removed under EU ruling. Yes, the European Union is a protectionist Union but after all, it is to protect us Europeans. 

Brexit is not about democracy but disruption!

Brexit is a far-right European Union infiltration disruption Project. 

Remember that anything that has been coated or soaked into any timber that we want to work with our machines will expel its toxins in the form of wood dust.
