    Banning it is not the answer, regulating the industry is, they need to put in a set of measures that each workplace has to adhere to, such as investment in wet cutting / grinding machines.
    Adequate PPE and have the authorities perform regular un-announced spot checks, if found in breach of the regulations fine them, if they persist, then close them down.

    It's about protecting your workers and yourself, knee jerk reaction of banning everything never achieves anything.

    It sure is.

    I know 30 and 40 year olds with it.

    way worse than asbestos because we’ve known about it for 50 years but do nothing. Also because it hits so young. Also because engineered benchtops are like 80%+ crystalline silica

    dry cutting I think was the biggest issue but there will be a lag between the ban and a reduction in cases. You cannot guarantee the extraction is doing its
    job without specialised air monitoring because a hepa filter could be releasing particles smaller than 5 micron and that’s smaller than the human eye can see so you don’t know you’re breathing it in. It’s the smallest particles that get buried deep inside the lungs and cause the chronic inflammation that leads to silicosis. I think issues become firing up wet cutting polishing machines that have sat overnight and the dust has dried. That may aerosolise dust which the workers breath in all day.

    small particles can remain airborne for hours even in absence of breeze. This is the issue with disturbing asbestos is that the smallest fibres may never settle in a household with regular movement.

    that being said the young blokes getting silicosis usually report working in a cloud or haze of dust all day every day for years.

    was the same story with asbestos workers. What didn’t make sense was their wives who just banged out the clothes and weren’t in it all day also got meso

    S900 - similar story with MDF although based on doctors feedback you usually know its it an issue within 12 months, not 20 years like asbestos.

    After working with the stuff for years, neighbor got brain cancer from a MDF particles lodging in his sinus's of which a biopsy/removal clearly showed MDF particles. Doc said he is seeing a lot more of it.
    It was very aggressive and kept coming back growing to the size of an apple within 12 months. Got him in the end after 3 operations and approx 4 years later.

    I wonder if new mdf is safer. Low emission low formaldehyde. Still softwood and hardwood of all forms are class 1a carcinogens.

    The few times I’ve been slack with Ppe make me regret it when your hear of someone with it. It really is about constant vigilance

    marc I don’t know who to blame more for the rollout failure. Certainly the media trumping up the clotting issue hasn’t helped.

    currently only 25 casss out of 2+ million az doses in Australia and only 1 death.

    all this vaccine hesitancy saying they don’t know what’s in it. Wel do we know what’s in our water. Food the supplements we take. Some or even many of these people drink smoke and eat meat which are all carcinogenic. We know the risk of blood clots from covid itself is 10-15x that of the vaccine.

    the biggest issue is that the country has to open up to tourism eventually. It’s a huge part of our economy. It’s pure fact the gov can’t keep locking down forever. By the years end everyone will have been offered a Pfizer or moderna or maybe novovax and if people choose not to have it they’re actively damaging the country and the economy if they get sick from covid and need hospitalization. it costs 80-200,000 to have them on a ventilator for 2-4 weeks depending on what complications they have.

    A very small number of covid cases costs not only small businesses but huge amounts of taxpayer dollars as well. Look at this week lockdown. The estimated cost of this 1 week lockdown is 1 billion dollars. Because despite what everyone wants to believe. The 10-20% of covid cases that end up in hospital end up requiring a large amount of resources to keep alive and so we all have to go do our bit to literally save our country from economic collapse. And for me that means encouraging everyone to go get vaccinated.

    True, dust particles of anything are a hazard.

    MDF seems to have far higher concentrations of the chemicals (glues, resins, formaldehyde) and being a fine particle carries a degree of higher risk as opposed to say ply, chipboard.

    I choose not to use it with the exception of skirts on the odd occasion....but all cutting is strictly outdoors, upwind, with a mask/glasses and equip compressed air cleaned to minimise the risk.

    I remember him saying the doc says he regularly see patients affected by the aggressive MDF cancer with particles lodging behind eye's, noses, sinus's, ears, lungs, throat.
    Seen what he and his family went through and wasn't pleasant....maybe resulting in me being overly cautious with the product.

    I was thinking why can't the dust be cleansed out of one lung while living off the other and came across this:

    AFAIK the manufactured stone benchtops are made of silicon which is why cutting or grinding those products dry cause "industrial disease". These manufactured stones are referred to in the trade as "plastic stone"

    Traditional stone does not have the same impact and often is cut with water. In contemporary workshops much of the stone is now cut with water.

    New techniques now occur also which does not require grinding in the lamination process of plasi-stone as we call it in the trade

    Engineered stone is more plastic than it is stone

    This is why many tool manufacturers have now come out with better on-site extraction power tools. I have a cordless planer with WIFI vacuum extraction activation > Makita

    There is a quarry in the district which has rock with no silica, the local precast factory uses it in concrete to cast bridge beams & girders, then transports them to places like Melbourne , it is a high demand commodity with 10 years work booked in presently.

    Any dust particles be it organic or mineral if inhaled will cause some form of lung disease. No Silica means very little because the rock if cut will make equally dangerous dust, be it from oxides, feldspathoids mica and other niceties.
