Asbestos roof

[BMWST?]

I have heard some exorbitant prices for asbestos work and in most cases it really isn't warranted.

apart from the fact that it can kill you and is labour intensive and requires packaging and "special procedures" to remove.No one is forcing you to accept the prices.If you dont like it dont accept it.

There is a lot of miss info re asbestos,when all vinyl flooring had a make up of part asbestos,everyone went gaga when removing it,I know several flooring guys in their 60-70's still healthy yet they removed numerous yards of the shit over the years.Sure heavy concentrations of asbestos aint healthy,i.e wallboards by Hardi-ferodo are different story,but ceilings and other products with smaller concentrations of asbestos is no problem if the company is competant.

Have known a heap of people lifting vinyl by themselves who freak out when any small remnants of flooring are left,and show it had asbestos in it,the look they give is as if they're given a week to live.

Building products that contain asbestos should be left alone, unless they are damaged. That old D4 corrugated roofing works just fine and will last longer than more modern claddings. But if you want rid of it, make sure that you get professionals in who not only know how to safely remove it, but also how to safely dispose of it.

There are no building products in New Zealand that are comprised exclusively of asbestos, so don't work yourself into a foam.

My father worked with the stuff when he was younger and has serious health issues from it.

If at all possible, avoid the shit like the plague.

thanks for all your info posts. Gonna find me a coin stuck down the back of the couch & flip the damn thing to help make a decision! Nothing would need to be done straight away however it is there. Will get some roofing crowds in from around Wellington & start getting some quotes in then as some one said use it as a bargain point. Again, thanks everyone for your input.

It only takes one fibre in your lungs to cause cancer......

I know a fair bit about this stuff and if that was true we'd better start evacuating the Hutt Valley straight away. Petone Beach is covered in it from all the run off from commercial buildings and state housing. The air around Seaview is particularly full of it. The general population everywhere breathes hundreds, if not thousands, of asbestos fibres every day.

The workplace exposure standard above which you a required wear a respirator is 1 fibre per millilitre of air for chrysotile (white asbestos, the stuff most commonly found in asbestos cement products such as roofing) or 0.1 f/ml for croicolite (blue) or amosite (brown). Below those levels, a person working in that environment 40 hours per week for 20 years would not be expected to suffer any ill effects.

1 fibre per ml means about 500 fibres per the average half litre breath (or at 0.1 f/ml about 50 fibres per breath for the real nasty blue and brown shit which will not break down in one's lungs over time, unlike chrysotile, which appears to).

At ten breaths per minute at the "safe" level of 1 fibre per ml for chrysotile, that's 1,200,000,000 fibres inhaled over 20 years.

Yes the shit is really, really, bad for you, don't breathe it in if you can avoid it, and for fuckssakes don't mix it with your rolling tobacco every morning (they used to put it in cigarette filters and gas masks by the way) - but one fibre isn't going to kill you. It takes a cumulative dose of billions of fibres over a long period of time to do any real damage at all. Lung cancer usually requires an even higher dose.

the angle I was going to try to take...

get someone to look at it!

I know a fair bit about this stuff

Well according to my lecturer on the matter, and while not probable, and you would be very unlucky, it only takes 1 fibre lodged in your lung to cause cancer. Not a high chance but still a chance.

The fibres in the environment undoubtedly become bound to other particles, increasing the likelihood that you will cough it out before any harm is done.

Mate, when quotes come in for the same work thousands of dollars apart, the upper price is a rort.

THAT is why you do NOT sand OR water blast....

sorry i have not been around.. will be there tomorrow to look at your problem...

Hate to think how many asbestos roofs we riped off and chucked in the bin or over the bank.

That's good news, cause we used to blow this shit up in fires.
It fooken goes off.

The roof, the roof, the roof is on fire......

Oh no it isn't, it's made of asbestos.

I seriously doubt that the general popn are breathing in thousands of fibres every day. Can you reference any authority on this ?

Also, from DoL website regarding WES - "The Workplace Exposure Standards are intended to be used as guidelines for those involved in occupational health practice. The use of the standards by untrained persons as a marker in determining 'compliance' is not recommended. In assigning the standards, defining a level that will achieve freedom from adverse health effects is the major consideration. Compliance with the designated value does not, however, guarantee protection from discomfort or possible ill-health outcomes for all workers. The range of individual susceptibility is wide and it is possible that workers will experience discomfort or develop occupational illness from exposure to substances at levels below the exposure standards."

Although - "Possible Diseases Due to Short Term Asbestos Exposure
Low levels of short term asbestos exposure is not considered a threat to humans and can generally be overlooked."

I wouldn't risk it myself and wet the roof down thoroughly before doing any work.
