There are many very harmful elements that reside in raw sewage, and if you have a broken sewage pipe, a septic backup, or a municipal backup of sewage, you should simply call the best sewage cleanup company you can find. There are harmful pathogens such as salmonella, E.Colli and many other harmful substances. There may be pesticides and harmful chemicals as well. Just breathing raw sewage can be harmful to your health. You should leave it alone yourself and not attempt to clean anything up yourself, as you not have the equipment, experience and the protective clothing needed for the job.
There can be gasses contained in raw sewage that are flammable, which have the potential to catch fire. Older sewage systems can wear out and break simply due to their age. The stench and potential danger should not let you think twice before you call in the experts who can handle the problem while you stay with friends or relatives for a few days.
Most sewage cleanup companies are available day and night will come right to the scene so they can assess the damage and make a sound, but quick decision as to what must be done. They will first get rid of any liquid sewage, and then dry the area out and sanitize the area. Any property such as couches, carpeting, draperies, pictures and other vulnerable items will probably have to be thrown out. Then everything will have to be totally sanitized and sterilized, or rebuilt. Keep in mind that the longer that the sewage remains in the home, the more damage that will be done.
In order to totally sanitize everything, things will either get clean or it will be destroyed. This could amount to rebuilding an entire section of a house to be sure that there is no element left at all that could possible regrow mold, bacteria or other virulent pathogens.
When such an event as a sewage backup occurs, it is always a surprise, even if you can see it coming, what can you do to stop it? You certainly are not going to plug the hole with some towels. About all you can do is get out of the house and call the experts. Call someone as soon as you can because the sooner that they are on the job, the sooner they can stop the flow, and get things right again. The experts will have the right experience and equipment that will be needed to get your home back in good living condition.
