Is this broken ceiling tile an asbestos hazard? [Pics Included]?
Question by Chaucer: Is this broken ceiling tile an asbestos hazard? [Pics Included]?
A few months back, a leak in the ceiling allowed water to pool atop a ceiling tile and cause it to collapse in the center. The debri was swept or mopped up, I don’t know (but the floor has since been mopped) — however, the tile, still broken, is just hanging there from the ceiling, and has been for all this time. Now, from what I’ve heard, the general rule of thumb is that any ceiling tiles pre-80s is liable to contain asbestos, while 80s and onward are generally regarded as being safe. I have no idea how old this ceiling tile is, nor how old the rest of the offices are for that matter. The warehouse is certainly old, yes, but the office space which this is part of was built later on. Perhaps these visual aids can allow someone with an astute eye to determine the relative age of the offices, and/or be able to state whether there is indeed a reason to be concerned about asbestos exposure or not from this. In my understanding, asbestos was used only in the more hard, acoustic ceiling tiles, but I’m not an expert.
This is a workplace, by the way, so we’re breathing this air regularly.

No, it’s not.
-they didn’t start using grid ceilings until the late, late 80′s and that isn’t even remotely asbestos laced. I thought maybe by your post you were dealing with the perforated stick on tiles that affix to the ceiling.(they are 10″ X 10″)
The tile you have can’t be older than ’89. Go to Home Depot and pick up a new one, 5 bucks.

Alex Jones – WHO Lists Cell Phones as Cancer Hazard!
May 31st 2011 The United Nations’ health agency, the World Health Organization, now lists mobile phone use in the same “carcinogenic hazard” category as lead, engine exhaust and chloroform. www.cnn.com But no adverse health effects have been established, the agency explains. The decision to list cell phones as a cancer hazard came after a team of 31 scientists from 14 countries examined peer-reviewed studies on cell phone safety. “The biggest problem we have is that we know most environmental factors take several decades of exposure before we really see the consequences,” said Dr. Keith Black, chairman of neurology at Cedars-Sinai Medical Center in Los Angeles. Numerous studies indicate prolonged cell phone use is hazardous. The European Environmental Agency has pushed for more studies. It says cell phones may be as big a public health risk as smoking, asbestos and leaded gasoline. In 2009, WHO reached the same conclusion. A decade-long, million study into cell phones found a link between long term use and brain tumors. The WHO’s Interphone investigation’s results showed “a significantly increased risk” of some brain tumors “related to use of mobile phones for a period of ten years or more,” the Telegraph reported. There are only to ways to limit or stop radition from phones!. 1. Use the Speaker phone on your phone and talk while it is on the bench. 2. Buy a Air-tube Headset.

landlord responsibilities with a health hazard and dangerous building?
Question by : landlord responsibilities with a health hazard and dangerous building?
Renting a home from a landlord for a year. Landlord is paid. The house is a fire hazard, pipes are leaking, and I would guaratnee that the air is filled with mold and/or asbestos. The landlord refuses to do anything, saying that the contract assures him of no responsibility.
I can’t afford a lawyer, nor would a lawyer and lawsuit get me far in this somewhat short period of time. What can I do. Can I call the department of health? Will they inspect and/or be forceful with this landlord?
Thanks.
Best answer:
Answer by jaker
Have you read the contract? You should have a copy. If the landlord is correct and you signed a contract that says that you, not he, will be responsible for these things then you are. If not, and he refuses to fix them you should declare the contract void and move out.

Answer by science teacher
You seem to be talking about a commercial building. Laws enacted around 1980 said asbestos had to be removed from public buildings. Many buildings underwent renovation at this time to make the changes. Probably some did not. If asbestos is no moved it is safer than if it s broken up. It is breathing the fibers that causes the asbestosis and other lung diseases.

Not true, greeneye. Asbestos must be made airborne in order to pose a risk (it’s only a hazard when it’s inhaled). For this reason, intact objects containing asbestos are safe so long as they are not disturbed. The danger is when such objects are broken, and the asbestos becomes friable and is released into the air.
We don’t have the money to put towards any kind of asbestos inspection/removal services. What will probably happen is the tile’s going to end up just getting ripped down, and the debri nonchalantly swept into the garbage. Pretend the tile does contain asbestos, and we dispose of it that way… would it even release enough asbestos to constitute a genuine health threat? Some people say it takes a lifetime of asbestos exposure to cause mesothelioma, others say it only takes a few exposures….

A.

B.
their radiation strikes the skin.
C.
exposure to them is external.
D.
none of the above
Best answer:
Answer by cat lover
Alpha emitters have very poor penetration ability. So it takes very little for them to be blocked. But what happens if you get them inside you? They simply radiate over and over the immediate area of the radioactive particle. If they were strong emitters, the radioactivity would simply pass out of your body, doing far less damage to tissue.
So if you haven’t figured out yet, the answer is (A).

Q&A: What can I do to make sure this strange white powder coating everything on my job isn’t a health hazard?
Question by WriterChic: What can I do to make sure this strange white powder coating everything on my job isn’t a health hazard?
My job relocated from a clean modern building with great maintenance and security, to a dirty rodent infested building that’s at least 40 years old because it was more cost effective.
The water fountains are turned off because of the lead pipes. There are mouse dropping in my cubicle everyday and the whole office is coated in a strange white powder. The building has repeatedly been sited by the health department but nothing has been done.
OSHA has tested the powder and says its not Legionaries Disease, which one of our other buildings did have, and its not asbestos, even though a contractor left the building and refused to complete repairs on our AC claiming the building had asbestos. They says it has a high mold content but that’s not something they deal with.
A lot of people in the building have a persistent cough and my desk is right under a vent so I not only have a cough but have horrible headaches as well.
I currently have to wipe my desk off with bleach wipes everyday just to keep the dust off my clothes. The dust is so thick when I come to work on Mondays that you can write in it. Plus its not like regular dust as its grainy. I really think this stuff is dangerous but I can’t afford to quit and look for a new job.
What can I do to find out what this stuff is? And how can I protect myself?
Best answer:
Answer by NurseKaia
I don’t know how you can find out what the dust is apart from reporting this to the Occ Health and Safety authorities.
You need to get yourself moved to a different desk. Tell your employer that it is making you sick and that you don’t want them to have to be liable for huge medical bills.
You say you cannot afford to change jobs but can you afford to get mesothelioma if it is asbestos? Even if it is something else, you are breathing that in and your lungs could form scar tissue around the deposits. Any type of irregularity in the form or function of your lungs can cause cells to get out of whack with their dividing and that is the beginning of cancer. At the very least you could get one of a number of lung and/or respiratory conditions
You have to either change jobs or move to a different area. Dust that you can write in is not good! Especially when it isn’t dust! Put pressure on the health department and if you can, put pressure on your employers. Let them know that it could end up being more expensive if they do nothing.
Good Luck and think of your future. When you are lying in a hospital bed suffering, you will wish you got the heck away from that weird “dust”.
