Mold Remediation Respirators

When you are working on killing or removing the mold from a building, the equipment that you will need to safely do this job can vary just a bit, depending on the size of the area you are trying to treat. You might just need some cloths, mold killing chemicals, rubber gloves, and a light respirator if it is just a surface infection like on a countertop or on a vinyl floor. But, if you are planning on tearing out any drywall and getting to an infection that exists inside your walls or ceiling, then you will need some protection equipment that is just a bit more extensive. There are different levels of protection equipment just as there are different levels of mold infestations and there are a few things that you need to know about respirators.

No matter what level mold infestation you are dealing with getting rid of, you will need an N-95 type respirator. This is about the minimum level of protection that you can use and the next level down would be using none at all; this is, of course not advised. When you are cleaning, mold spores are stirred up into the air, especially if you are taking out drywall or removing contaminated wallpaper, so even if you have been living in a contaminated household for a while, the risk you are taking by not using a respirator when you are getting rid of it is considerable. You can find this kind of respirator in most hardware and even some department stores.

Air purifying respirators are the next step up in protection and these always have HEPA filters in them. These filter out almost all particles that you are breathing in while you are working. This kind of respirator does not protect your eyes and are available in half face and full face kinds. The best thing about this kind of respirator is not only the HEPA filter, but also the fact that using this kind does not require any training. The next step in protection does.

The highest level of breathing protection will come from a powered air purifying respirator. These also come equipped with HEPA filters, but require electricity and some training in order to be able to use them. OSHA guidelines must also be followed to the letter if you are planning on using these respirators in a commercial setting.

All respirators must be approved for usage by the National Institute for Occupational Safety and Health.

The Most Frequently Asked Questions About Mold

If you are a new homeowner or even an old one that is just wanting to do a little studying on what this whole concern about mold is that you have been hearing about on the news and in magazines, then there are a few basic things that you need to know about mold

What causes mold to grow?

Well, mold requires a few different things to grow and these are nutrients, air, and moisture. Molds can grow in cooler temperatures down to around 40 degrees Fahrenheit and up to even around 100 degrees Fahrenheit. If it gets cooler than 40 F, most molds will become simply dormant and cease growing. They are hard to kill by change in temperature alone. Temperatures above 100 F have been reported to kill mold and its spores, but the exact temperatures that are needed to kill specific species of mold are uncertain.

How does mold get into your house?

The truth is that mold is always in your home, but it only grows there when conditions are favorable. Spilled water on carpet that is never cleaned up, condensation on windows or water pipes is a sign of high humidity that helps mold grow, as well, and even something as seemingly harmless as packing your clothes too tightly in the closet can cause mold problems.

Do harmful molds exist?

Yes! While there are only a few different kinds of mold that cause human health issues compared to the thousands of different varieties of mold there are in the world, mold growing in your home can be a serious health risk.

Does mold cause health issues in everyone? Are they always the same?

No, mold does not typically affect one person the same as another. One person might be allergic to the mold growing in the home and another may not. Some molds can cause infections that are serious enough to see a doctor for and some can cause brain damage, miscarriages, birth defects, and in some cases, even death.

What can I do to prevent mold growth in my house or business?

There are a lot of things that you can do to prevent mold from growing both on the constructed parts of your home and the items that you have inside it, such as furniture, clothes, and etcetera. There are numerous articles online to help you in preventing mold from growing, but the general consensus is to not have a high level of humidity in any area of your home, such as in a bathroom that does not have a vent to allow steam to exit the room while bathing. A similar vent should be installed in the kitchen near the stove.

Mold Just May Be Your Fresh Fruits Greatest Enemy

Fruit rot in blackberries, strawberries, and raspberries are usually the result of one chief offender and that offender is known as gray mold. Gray mold is able to affect not only the fruit itself, but the petals, stems, and the flower stalk. Fruit are a popular breeding ground for mold, due to the juices in the fruit. A wet environment is the ideal place for mold to try and grow, and the juices contained in the fruit helped provide just the environment mold calls for. Gray mold is considered the most serious disease, especially during a warm and rainy growing season.

The kind of fruit with the least amount of protection against gray mold infection is young fruit blossoms. And when the infection becomes apparent in large clusters of fruit. The blossoms will show the infection as a soft, light brown and the spot will continue grow at a fast rate. The fruit will become powdery and gray if the fruit is left defenseless against the mold. This is where the name “gray mold” originated from.

The areas of the fruit that are most susceptible to infection are located near the middle of the plant where the branches and leaves cause high humidity and air circulation is lacking. If the fruit has been exposed to the ground where soil has captured water condensation the risk is higher, as that condensation will attract bacteria and will cause mold to grow. As the mold grows, the rot will begin to set in and any fruits nearby could be infected if not tended to in a timely manner.

And while mature fruits are less susceptible after they are picked, they are susceptible never the less. However, recently harvested green fruits will become just as infected, and the disease isn’t usually detected until the fruit is fully ready to be harvested. Bruising or breaking of the skin is a major cause of the infection in mature fruits. This is, once again, because of the juice on the inside of the fruit attracting bacteria. The mature fruit can be completely rotted in as short an amount of time as forty eight hours.

There are, however, ways to prevent gray mold from infesting your fruit. First, you should select where to plant a fruit where there is a decent amount of soil drainage and air circulation. They need to be exposed directly to sunlight. You should also make sure to keep the garden weeded, as it helps airflow.

A Few Tips For Employers To Protect Employees And Business Against Mold

When we go to our daily work place, we usually like to believe it to be a very safe environment. However, one safety aspect that is often and sadly overlooked is that of mold infestation. We usually believe that mold is not a problem to have to deal with in the work place and that mold is a problem that is only dealt with in the home. However, any building is equally susceptible to mold infestation. If you are an employer, you are therefore responsible for the safety of every person who is inside the building. If you do not make sure that mold is not in the building, you could be liable for any medical expenses that one of your employees may have as a result of exposure to mold in the work place. If you suspect that there may be mold in your building, you must first conduct your own testing. If you do, indeed, find mold, it is your responsibility to send off the mold samples to a laboratory that specializes in mold identification. You should receive your results within a few weeks to a month.

The first thing you should do upon finding out that there is a mold infestation, and what kind of mold it is, is to inform your employs that there is a problem. You should inform them of what measures are to be taken. You should next call an inspector as to determine how extensive the contamination is and if the case is mild, and can be dealt with in a short amount of time, or if the case is serious and could take up to several weeks to remedy. If the case is extreme, you should notify your employees that they are being laid off for the duration of the remediation process. You should tell them when the process will begin, and give an approximation of when the process will end.

You should also ask your employees if they have been experience any kind of health problems since working for you. Specific health problems that you should look for are respiratory problems, skin rashes, and any other kinds of complications commonly associated with mold.

If your building is indeed contaminated, it should never be ignored, be it your home or work place. If you can afford to pay for the medical bills of others, you still do not want there to be health problems for yourself.

Asian Food Is Highly Popular And Is Made With Mold

You can hardly find a person who does not like Asian food and anyone who enjoys soy sauce is not alone. In roughly two thousand years soy sauce has become one of the most popular and consumed condiments in history. Soy sauce originated in Asia, because in ancient times Asians had to package meat and fish tightly in salt in order to preserve the meat and excess liquid would be drained as a result. The liquid, which has soaked in the meat and salts flavor, would be used as a seasoning for other foods, like noodles or rice. However, when Buddhism began to rise in popularity, there was a shift from eating meat to eating vegetables and, therefore, the recipe for this seasoning also had to change. The recipe went to a salty paste of fermented grains. It was this recipe that became a prototype for soy sauce.

The recipe spread to Japan where it was modified and improved and a woman opened the world’s very first commercial brewery specializing in soy sauce. It was then that soy sauce’s popularity began to skyrocket.

Soy sauce, in the modern day, is made using mashed soy beans, wheat, salt, and a fermenting agent which is the very same kind as used in the production of sake, Aspergillus oryzae. Aspergillus oryzae is a popular alternative. This mold is the most important ingredient in the making of soy sauce. It is this mold that makes it true soy sauce.

The previously mentioned Aspergillus oryzae is used in other things as well, such as Japanese rice wine. The mold is used to ferment rice that has been steam and milled down to around 50 percent of its original mass and weight in order to remove amino acids, proteins, and fats that can make the smell of the wine less than pleasant.

Sake brewers take the cultivation of this mold at the utmost seriousness, because the mold is capable of absorbing surrounding odors. The same goes for flavors. For example, if the wood of the brewing wood is cedar, a slight cedar flavor will be absorbed. The mold is helpful for precisely these reasons. Sake and wine have a tendency to age in very different manners. Sake should be drunk almost as soon as it is purchased. While sake can, at times, taste better with age, it usually just tastes less than spectacular. Try some of these foods, You might find the you like them if you have not tried them.

Your Allergies May Be More Related To Mold Than You Think

With the teeming masses of people in the world that suffer from allergies, no matter the number of medications used, it is nearly impossible for them to find an escape from their allergens. The reasons for seasonal allergy symptoms are many. Most allergies are attributed to grasses, pollens, and various kinds of mold. Now, these three allergens are incapable of growing during the winter time. And while some molds can withstand colder temperatures than others, the majority of molds cannot continue to grow in these cold temperatures. Instead they manage to lie dormant for quite some time. They go into a kind of suspended animation when frozen, and if they thaw they will continue to live and they are equally as dangerous as before the time they were frozen.

However, in some areas of the world there is not a winter, and therefore, no freezing temperatures. And in these areas, people who live in apartment complexes and places of this nature are faced with considerable risk of infection, especially those who are highly allergic to these molds. The list of symptoms experience from an allergic reaction is long and varied, depending entirely on the specific allergy. The most prominent symptoms are runny noses and skin rashes. Perennial allergic rhinitis can be brought on by the presence of mold, as well. However, these allergic complications are usually only brought on by a high population of mold. The symptoms, however, can worsen if food that has been created using a type of fungus, such as mushrooms, bread, beer, and even yogurt. Blue cheese is also a chief offender.

While there are thousands of species of molds on the planet, the number of highly allergenic molds are fortunately only in the dozens. Cladosporium, Penicillium, and Alternaria are the three most well known kinds of mold to cause many allergic reactions. As a bit of trivia, Penicillum is the only genus with both a medicine as well as a disease named after it.

It is important that you stay on constant watch for grass, mold spores and pollen counts for each day on the news, if you have allergies. These daily reports are recommended, especially for the elderly or anyone who has a small child who may be allergic, and are planning an outing. This way, it will be apparent which areas to avoid. Severe allergic reactions are rare occurrences, but they happen never the less.

Bleach Is Not The Best Method To Kill Mold

People who run and maintain a household will probably contend that they use bleach to clean and disinfect just about anything that needs it, but what they might not be aware of is the fact that bleach is not the great purifier that we tend to think that it is. It has been used for years by dutiful housewives trying to get by without having to go to the store and buy another cleaner and it has come into light recently as being good for the removal of mold. Unfortunately, these claims are not true.

Bleach will do nothing to eliminate the mold that can occur on porous surfaces such as drywall. A study that was paid for recently by Clorox, the largest manufacturer of chlorine bleach in the world, states that trying to get rid of mold using bleach is to effective on nonporous surfaces only and that trying to use it on porous surfaces will only have a temporary effect. This would mean that if you see mold growing on your ceiling or on another part of your wall, then trying to use chlorine bleach to kill it will only work on a superficial and cosmetic level. The mold is likely to have contaminated the entire depth of the board and will only grow back later.

The EPA also does not classify chlorine bleach as a registered disinfectant that will terminate mold infections. Every bottle of disinfectant that kills mold is labeled with a registration number and there is no current brand of bleach in existence that has this label.

Also, in the effort to save the time of going to the store and buying more chemicals and in the interest of saving money, some people who attempt to get rid of mold themselves are often guilty of believing that mixing household chemicals can somehow “up the ante” and give them an advantage of some sort. It is a misconception that mixing household chemicals can somehow make them more effective and it is also dangerous. Chlorine bleach should not be mixed with any other household chemical, especially anything that contains ammonia. When chlorine bleach is mixed with ammonia, it can give off hazardous fumes and if your home is not properly ventilated at the time, these fumes can do serious harm to you. When attempting to remove mold from your home or business, it is always best to purchase chemicals that are reputable and advertised as able to kill mold.

Mold Can Hurt Your Pets Health

If you have mold in your place of residence and you are a healthy adult that is not responsible for the health of anyone else, you might think that it is alright to continue living there until you can afford to have the mold removed professionally. But, while there may be no other humans that you are responsible for, do you have any pets? If you do, you might want to reconsider allowing your pet to stay with you until you can have the mold removed. Our pets are particularly at risk for developing mold-related health complications.

Something that has recently come under fire is the use of dogs to detect mold in homes and other buildings. This is not only ineffective compared to other methods, but it is also very harmful to the health of the dog. By the time the health complications of the dog show as symptoms, it is often too late to do anything about it and the animal must be euthanized. These dogs are trained to deliberately inhale mold spores, which is something that humans are repeatedly told NOT to do. Humans are told that they should always wear respirators when having anything to do with mold, so why would it make any sense to use a dog to do this job when there are other methods that are so much more effective? A dog cannot tell you what kind of mold you are dealing with, how toxic it may be, or in what quantity it exists in the home.

Dogs have not only been shown to contract aspergillosis from contact with mold, but also other conditions such as blastomycosis.

Aspergillosis can form as allergic reactions involving coughing up blood, fever, and weight loss, among some other symptoms, but it can also show up as the growth of fungus in different cavities of the body both in humans and in pets. Aspergilloma often have no symptoms at all and when they do finally surface, their symptoms can also include the coughing up of blood along with other symptoms of aspergillosis.

Blastomycosis is caused by Blastomyces dermatitidis and it occurs more in large male dogs that are of hunting breeds than most others, however, all dogs are at risk. It has been known to cause pets to develop pneumonia, other respiratory infections, and skin infections.

If you suspect mold in your home, think not only of your own and your family’s health, but also of your pets. They are some of the most at risk.

How To Keep Mold From Calling Your Fridge Home

Finding mold growing in your refrigerator is something that we cannot usually avoid, because mold exists everywhere we are and it grows on dead organic materials, just like what we keep in our refrigerator. There are ways, however, to reduce the amount of mold that will grow in your refrigerator.

You should take inventory of your refrigerator and anything that is outdated beyond use should be thrown away because if mold is not growing on it now, it will eventually. The sooner that you forget an outdated item is in your refrigerator, the sooner mold will begin to grow inside it and spread to other items nearby. The spread of mold in this way is especially true of fruits and vegetables that are often stored in a bin on top of each other. One infected item can affect the whole bin and make it inedible. It is best to go through these items as often as possible to make sure anything contaminated is removed.

When you bring fruits and vegetables home from the grocery store, we often have them in the plastic bags that we used in the produce section to pack them in. You should probably remove these items from the bags in order to reduce the amount of condensation they are exposed to. Condensation will build up inside the bag as water evaporates and mold will begin to grow.

Cleaning the refrigerator regularly is also essential to slow the growth of mold. Everything in the refrigerator should be washed thoroughly and since no surface inside it should be porous, using chlorine bleach to wash the inside should be fine to assist in removing any mold that has begun to grow. Whatever you choose to clean your refrigerator with, please do not mix household chemicals when cleaning your home. The results can be harmful or even deadly if you mix the wrong two, such as bleach and ammonia.

Before you really start cleaning it out, take the light bulb out of your fridge because they are not made to be left on for more than a few minutes and will possibly burn out if you leave the refrigerator door open for too long.

After you are done washing the inside of the refrigerator, take a few minutes and go through everything as mentioned earlier and throw out anything that you think is too old. Washing down the outside of the refrigerator is also a good idea.
