2·3 days agoI have no idea, but would presume they could very well have used corded fabrics!
Gimp: Noun: A narrow flat braid or rounded cord of fabric used for trimming. Also called guimpe, guipure.
2·1 month agoThe dusty exposed have been dropping like flies with ME/CFS for ever and a day.
The community has been calling on governments to recognise, research and act for very many years .
During one government hearing (Which actually became two hearings due to the COVID outbreak) the similarities between long COVID and dust induced autoimmune diseases were well noted and published in the final report, but calls for further research were only to be ignored once again.
As one specialist research doctor explained some years ago (Long before COVID)…The reason we were fighting a losing battle for research and recognition with governments was that such conditions could also be triggered by many chemicals and even air pollution, therefore if they recognised one agent as causative then they would be forced to admit to all the others .
So yip, dusty guys are very much aware of how desperately research into these conditions is required and also how the system works.
Occupational hazards perhaps ?
Yip, here in the UK there have been several diseases named after brake dust pollution!
But who is acting on this confirmed medical research?

This was indeed a horrific incident.
And the exact number of people who died due to working there is still unknown!

I would think so, but conformation of this will be dependent on the researchers around the globe who as I type, are trialling such resurfacing ideas and methods. I would imagine any excessive particulate matter would be released by wear on the surfacing, whatever that might be ?
There are already several recognised diseases which are solely down to tyre and brake wear alone such as the well documented ‘London or City Cough’ here in the UK.
But hey…What could possibly go wrong?

Granite is a natural material whereas engineered stone is a man made manufactured material :
Granite is a plutonic rock that is composed of between 10 to 50% quartz (typically semi-transparent white) and 65 to 90% total feldspar (typically a pinkish or white hue). Granite is an intrusive igneous rock, which means it was formed in place during the cooling of molten rock.
Engineered stone silicosis
Engineered stone silicosis is an emerging disease in many countries worldwide produced by the inhalation of respirable dust of engineered stone. This silicosis has a high incidence among young workers, with a short latency period and greater aggressiveness than silicosis caused by natural materials.
Although the silica content is very high and this is the key factor, it has been postulated that other constituents in engineered stones can influence the aggressiveness of the disease. Different samples of engineered stone countertops (fabricated by workers during the years prior to their diagnoses), as well as seven lung samples from exposed patients, were analyzed by multiple techniques.
Some of the volatile organic compounds, polycyclic aromatic hydrocarbons and metals detected in the studied countertop samples have been described as causative of lung inflammation and respiratory disease.
Among inorganic constituents, aluminum has been a relevant component within the silicotic nodule, reaching atomic concentrations even higher than silicon in some cases.
Such concentrations, both for silicon and aluminum showed a decreasing tendency from the center of the nodule towards its frontier.
In the analysis of the lung samples, the presence of silicon, iron, aluminum and titanium in the granulomas was confirmed. Aluminum, in particular, was distributed in a relatively high concentration in granulomatous lesions.
One of the elements systematically detected in all samples was tungsten.
This has not been reported for any previous series, and we cannot rule out that the procedure used by us to obtain the dust samples could have led to tungsten contamination (steel bits with tungsten carbide tips).
The addition of elements contributing to Engineered Stone dust has been verified by other authors who used similar tools in the processing of the material; the results can also differ based on dry or wet processing
Why is RPE the last resort or last line of protection?
RPE can only protect the wearer. Control measures at source (at the point where hazardous substances are released into workplace air), such as local exhaust ventilation or enclosures, protect all those working in the area.
So, only use or provide RPE as a last line of choice for respiratory protection. Consider other control measures before deciding upon RPE.

Exactly and a point many cannot seem to understand, most occupational diseases are as a whole, caused simply by ignorance : The time to change this corporate ‘for profit over all’ ideology has well past. You take care sir and try not to worry . As with your elders, I am quite sure the heart failure will get you first ! Live long and prosper dude
That shit is mass produced over here in garages and garden sheds, the only substance that does go into every batch of whatever the manufacturers have to hand is the colouring. Taking it is even more dangerous than giving it a label !

This is exactly what the research guys have concluded, whether it be dusty folks in war zones, emergency service personnel or just your ordinary, average everyday dusty dude in the street. The inflammatory response is triggered by a build up of nasties in the body, a combination of toxins, fine particulates and biological pathogens, the end result is immune dysregulation…Bingo!
And again, what you consider to be merely an economic issue is exactly where you seem to be missing the point.
Quarrying is environmentally destructive. It has contamination and pollution issues. It carries health issues. As well as the costly logistics of transporting bulk around the planet. Governments these days no longer wish any company, large or small, to go around tearing rock, in any form - pre ground or otherwise -out of the ground. So your next problem would be sourcing the base materials for your manufactured product legally.
Economically, even if you did manage to quarry,crush,sieve,grade and mix your sand for lets say £1000 a ton. What architect on the planet would specify the use of such an environmentally unfriendly and costly material and what construction company in the world would pay such a price?
Architects are already specifying more sustainable materials and construction techniques are changeing, but at present, people are still destroying the planet and killing each other for sand ! That’s the current economic situation.
Nobody is saying that without a time limit and at great expence sand can not be manufactured, but it is not even that simple.
Firstly : You would have to quarry your rock of preference before crushing, sieving, grading, and more than likely, also having to transport your specific rock grains to be mixed with other types of crushed and graded chips, depending on your sands ultimate purpose.
Secondly : It is not cheap to extract stone from the earth plus quarrying leaves very big holes in the ground! Permission from authorities to open new quarries or pits is not easily obtained in most countries.
Thirdly: Crushing is hazardous, polluting, environmentally destructive and very expensive .
The sand problem has been bubbling away on the back burner for years, hence the many and various ongoing efforts from all around the globe to recycle or create new and innovative construction materials.
Why the world is running out of sand
Our planet is covered in it. Huge deserts from the Sahara to Arizona have billowing dunes of the stuff. Beaches on coastlines around the world are lined with sand. We can even buy bags of it at our local hardware shop for a fistful of small change.
But believe it or not, the world is facing a shortage of sand. How can we possibly be running low on a substance found in virtually every country on earth and that seems essentially limitless?
The problem lies in the type of sand we are using. Desert sand is largely useless to us. The overwhelming bulk of the sand we harvest goes to make concrete, and for that purpose, desert sand grains are the wrong shape. Eroded by wind rather than water, they are too smooth and rounded to lock together to form stable concrete.
The sand we need is the more angular stuff found in the beds, banks, and floodplains of rivers, as well as in lakes and on the seashore. The demand for that material is so intense that around the world, riverbeds and beaches are being stripped bare, and farmlands and forests torn up to get at the precious grains. And in a growing number of countries, criminal gangs have moved in to the trade, spawning an often lethal black market in sand.

You could be right on the governments dislike of a popular and profitable imported product!.. But what about RPE ?
RPE will not eliminate disease in cases of extended long term exposure.
RPE has only to be used as ‘The very last resort’…and is only supposed to be used as…‘The very last resort’…and only as…‘The very last resort’ for short periods of time, as…‘The very last resort’
Why do so many people equate the usage of respiratory protection with ‘A Safe Working Environment ?’
In areas where long term usage of such protection is required, an operatives working environment is exactly the opposite of ‘SAFE’ !
There is No Known Safe Working Exposure Limit when working in respirable crystalline silica dust…NONE !
Do I sound upset ? Crikey! ha ha
Sorry duder ,I am immune to upset and trivialities such as social media comments do not even register as irratation on my ragged toenail scale.
I do attempt to upload the original paper where possible, but when (As is par for the course these days) the publication is behind a paywall and as in this case, without even an abstract ,then the news article has to be the option for the post.
Take care and have an article annoyance free day .
Not my headline and I did not write the article
Here is the actual report ,crikey you have to pay for it !!.. Well what a bummer ,there is the reason for posting the news article instead of the actual report…Happy Now ?
Large Study Links Industrial Solvent in Drinking Water to Parkinson Disease Risk in Camp Lejeune Veterans
Neurologist Samuel Goldman, MD, MPH, had long felt obligated to dive into the question of whether the volatile organic compounds (VOCs) that had contaminated the drinking water at Marine Corps Base Camp Lejeune up to the mid-1980s were associated with an increased risk of Parkinson disease.

Yip,that’s what it is alright, and it also has a tendency to come accompanied by one or more other real nasty conditions, which here in the UK anyway, are not deemed to be as of occupational origin!
