Stopping the foil insulation rollout will not stop the danger from the insulation scheme, and safety checks will be next to useless.
Foil insulation and its installation method is inherently unsafe. It may very well have good insulating properties, but so does asbestos, and we don’t use that anymore and we remove it where we find it because it is unsafe.
Foil insulation will kill you a lot quicker than asbestosis will. Here are just a few likely scenarios that could evade Garrett’s new safety check.
- If there is rubber cable in a ceiling that deteriorates and comes in contact with the foil above it, the ceiling will be live.
- If a staple has gone through a lighting cable that is not regularly used (such as a pantry light, or an exhaust fan) the fault may not be present for many, many years until there is congruence of circumstances with that appliance being on and someone being in the ceiling.
- If you have vermin in the ceiling and they chew through insulation to expose the conductors and they come in contact with the foil, the ceiling will be live.
- If you have a recessed light fitting that develops an earth fault and the foil is resting on it, the ceiling will be live.
- If you have a fault caused by a burnt neutral, removed or missing MEN link in the switchboard and you have bare earths in the ceiling (very common in pre 70’s houses) there is a good probability ceiling will be live.
- Dad/handyman/electrician mount something on the ceiling with a screw and it goes through a cable and into the insulation 50mm above the gyprock, the ceiling will be live.
There are so many different likely scenarios it is scary. It is not a matter of possibility that a ceiling with foil insulation becomes live, it is a matter of real probability. I have already told our employees that we do not work in ceilings with foil unless the power is isolated to the entire house.
This also presents a very real maintenance issue: if you are tracking a wiring fault in a ceiling or installing new cabling, you have to remove or disturb portions of the foil to complete the work. The act of doing this could actually cause a fault that was not there before.
All invoices submitted by electrical contractors in Qld must have a “certificate of test” attached which makes them liable for the safety of that installation in perpetuity to the effect of the work they have performed, in this case the electrical safety of the installation with regards to the foil insulation. No responsible electrical contractor would put their name on an invoice. I believe there would be a very real, sleeping liability for anyone putting their name to such a safety check.
You cannot see any of the cabling in these type of installations as the foil is put over the top of the ceiling battens. Therefore you cannot put your hand on your heart and say it is safe unless you pull the insulation up again and inspect the condition of the cabling, connections, and light fittings underneath. My very real concern is that people will pay money to a sparky (unscrupulous or foolish enough) to tell them it’s OK, and give them a false sense of security.
Foil insulation should be removed urgently. I am not being alarmist when I say that it is a certainty that more people will die. The victims in the future will not be 16 or 18-year-old installers — they will be plumbers, electricians, or dads putting the camping gear or the Xmas lights up in the ceiling.
This will be a deadly legacy of this stimulus package that will kill people 20 to 30 years into the future unless the foil insulation is removed and quickly. To be fair, it was installed previously and there was an Australian Standard for its installation. However, the flood of unskilled and inexperienced installers into the market, armed with nothing but a Stanley knife, staple gun, and a roll of glorified alfoil made installation standards plummet. What was previously an el-cheapo, less safe product for insulating a home became a deadly, unsafe product.
Chris Bowen repeatedly defended Peter Garrett on Lateline this week by saying Garrett had sought “expert advice”. A warning from the peak Electrical Contractors body in the country surely has to be considered “expert advice”. They had no axe to grind in issuing a warning about the safety of the foil insulation, other than the protection of life and property. This was an entirely foreseeable tragedy, expected and witnessed by people like myself who make a living by managing, preventing, and correcting electrical risk every day.
If Garrett wants to get on the front foot with this, he should announce that foil insulation method is banned, and instigate a policy of removal immediately. Putting all politics aside, as a bloke who is climbing into another ceiling tomorrow and sending people out to do the same on my behalf, I want to make sure we all have a better chance of going home safely.
What silly scaremongering. It all depends on where the foil insulation is installed. I put it up in my roof under the rafters. So it acts like sarking which is, shock horror, a foil. Sure if you staple aircell or the other foil insulation products on the ceiling joists you could have a problem. But you just need to be careful. It is not rocket science to avoid electrical cabling and downlights.
Poor Tim has missed the point totally.
But this statement from an obviously experienced tradesman should have become evident when Garrett was first warned a whole year ago – before anybody had died. It is so obvious now and should have been obvious after warning number one or two or three, to say nothing of the other ten warnings.
Chris is correct. Tim has missed the point. Foil installation should only be installed over the top of rafters and under roofing material as a sarking, and should be physically separated from wiring by at least 100 mm. At no stage should the electrical wiring be concealed by a conductor such as foil installation. Having crawled around in a few roof spaces in my time I am acutely aware of the hazards associated with wiring, especially older rubber wiring installed several decades ago. The issue of rodents chilling cable is real is apparently they need to wear down their teeth. All cabling is potentially susceptible to this type of activity.
As a matter of public safety, foil installation laid over roof joists should be banned, and any such material installed, whether as a consequence of subsidised installation or not, should be removed as a matter of public safety.
It is beholden on prospective state work safety authorities to order such a recall, even at the expense of a publicly subsidised removals scheme. It is pointless pointscoring against Garrett as he is such a soft target, and it would be an appropriate act of a statesman, if we can find one, to take responsibility for such an act of public safety, and throw aside the political ramifications.
Correction: would the moderator please replace “chilling” with “chewing”
I know nuffink but in these matters I defer to my bro who says
I too have followed the insulation foil fiasco in ceilings in the media.
The pictures on TV suggest that the installers lay the foil over the ceiling joists i.e. just above the ceiling and not up against the external roofing material (iron, clay tiles etc). This method of positioning the foil is implied in the comments by the electrician below .
As the sparky correctly points out, this method is dangerous.
Also it will not produce good heat insulation in the building.
To maximise its effectiveness, the foil should be up next to the roof and this means away from the electrical cables.
That way 90% of the radiant energy coming through the roof is repelled by the reflective foil before the heat gets into the roof cavity.
I wonder if this is in Garrett’s guidelines?
