## Title
Composition and method of dust suppression wetting agents

## Abstract

This disclosure teaches a composition and process which makes it possible to remove floating particulates or prevent the dissemination or particulates, by the misting of a solution that readily captures any particulate material in the air. More specifically, the present disclosure teaches the composition and use of aromatic compounds that are semi-volatile organic compounds (SVOCs) or slow evaporators in water-based carriers with surfactants as the misting/fogging agent for dust suppression. The particulate material is lowered to surfaces and removed by vacuuming, damp-wiping or using a dry cloth with a cationic charge (static cloth). This method can be achieved with neutral air pressure differentials in the work areas.

## Background
This application is a continuation-in-part of U.S. Ser. No. 13/507,712, filed Jul. 23, 2012, herein incorporated by reference, which is a continuation in part of U.S. Ser. No. 13/067,417, filed May 31, 2011, herein incorporated by reference, which is a continuation-in-part of U.S. application Ser. No. 12/155,447, filed Jun. 4, 2008, now U.S. Pat. No. 7,951,127, hereby incorporated by reference.


This disclosure teaches a composition and process for a dust suppressant composition which enhances the settling of air-borne dust and which is substantially biodegradable and benign in the environment. The composition makes it possible to remove floating particulates or prevent the dissemination or particulates, by the misting or fogging of a solution that readily captures any particulate material in the air. The particulates that are suppressed include but are not limited to. asbestos (chrysotile, amosite, crocidolite, tremolite, actinolite, anthrophyllite, etc.), asbestiform minerals, silica, metals, salts or manmade polymers such as nylon, plastic, fiberglass, nanoparticles, and combinations thereof. The use of the word “contaminant” shall refer to any and all contaminants and their combination thereof. Particulate matter can also originate from biological materials such as germs, insects, plants, animal based allergens, proteomic proteins of health concerns, etc. The particles can be from 1 micron to 50 microns or smaller which is measured in nanometers. 1 micron equals 1,000 nanometers.
More specifically, the present disclosure teaches the composition and use of semi-volatile organic compounds (SVOCs) or slow evaporators in water-based carriers with surfactants to be used in misting/fogging agents for dust suppression. The particulate material is captured by the fogged or misted solution or misting agent, whereupon gravity causes the solution to fall to the floor and other surfaces whereupon it is removed by vacuuming, damp-wiping, or by using a dry cloth with a cationic charge (static cloth). Any other method may also be used. Misting agents are sometimes referred to as “amended water” or water with a surfactant. The term “amended water” comes from 29 CFR 1926.1101 or the OSHA regulations for asbestos in construction. Fogging is another term for misting.
For the purposes of this application, a semi-volatile organic compound (SVOC) is an organic compound which has a boiling point higher than water and which may vaporize when exposed to room temperature (or higher).
Following or during the removal of asbestos or dust laden materials during the renovation or demolition of a building, ship, or machinery, a fine mist or spray should use the composition containing the semi-volatile organic compounds which is preferably applied to suppress and trap asbestos, dust, and other airborne particles.
These SVOCs include but not limited to: phenols, phenyls, benzyls, glycols, glycerol, butadienes, carboxyl groups, terpenes, phthalates, anthracenes, isophorenes, plant esters, ketones, amines, glycol ethers, pyrenes, toluenes, heterocyclic compounds, polycyclic aromatic hydrocarbons, mono and di aromatics, polyols, xanthenes, plant essential oils, enzymes from microbes, etc, and combinations thereof. The most preferred compounds are phenol, sodium phenate and glycerol. However, the choice of SVOCs may be dependent on humidity, temperature, overall climate, material being removed, gallons per hour of mist spray, cubic feet of air being cleaned, etc. Also, a mixture of SVOC's may be used, so that different particles of different sizes and charges may be captured. A preferred mixture of SVOC's may include phenol: 1.56%, and sodium phenate: 0.06%
The SVOCs may comprise from between about 0.25% and about 20% of a mixture by weight, with a preferable range of between about 0.25% and about 10%.


In one embodiment of the disclosure, the use of these compounds will require respirators that have filters rated by CDC NIOSH for “organic vapors” to follow OSHA regulations.
The mixture also contains surfactants and/or detergents to help keep the water tension at a desirable level to bind the particulate materials. Surfactants and/or detergents also help emulsify the SVOCs in the water carrier. The surfactants and/or detergents that are used may be borates, cationic surfactants, anionic surfactants, neutral charged surfactants, amid surfactants, etc. These compounds include but are not limited to: Sodium dodecylsulfate (SDS), Sodium deoxycholate (DOC), N-Lauroylsarcosine Sodium salt, Lauryldimethylamine-oxide (LDAO), Cetyltrimethylammoniumbromide (CTAB), Bis(2-ethylhexyl)sulfosuccinate Sodium salt, 1-Octanesulfonic acid sodium salt, Sodium 1-butanesulfonate, Sodium 1-decanesulfonate, Benzalkonium chloride, Benzethonium chloride, N-Dodecyl-N,N-dimethyl-3-ammonio-1-propanesulfonate, lignin based surfactants, coconut based surfactants, etc. It is preferable to use sodium dodecylsulfate (SDS), as surfactants, and most preferable to use sodium borates. A mixture of cationic surfactants, anionic surfactants, and nonionic surfactants can be used. Overall, the total surfactants can range from about 0.1% to 3% by weight.
Other components may be included in the solution. These components include:

There is little need for adding emulsifying ingredients since surfactants and detergents tend to emulsify the SVOC's that are slightly miscible. There is also little need for adding preservative ingredients since surfactants, detergents and some SVOCs tend to act as preservatives (examples: Phenols, quaternary ammoniums, etc).
Different combinations of aromatic compounds (SVOCs) and surfactants can be mixed at small amounts each to achieve the same as large amounts of a singular aromatic SVOC compound and a singular surfactant. Mixing combinations of compounds may lower toxicity while maintaining the benefits of the disclosure. The aromatic compounds are also emulsified so the water molecule(s) slowly evaporate without creating any permanent films like a paint, polymer, plastic, etc.
Another embodiment includes a fire retardant, particularly when the solution contains glycerol, propylene glycol, or other combustible chemicals. In one preferred embodiment, the fire retardant is a borate. In another preferred embodiment the fire retardant is a sodium or potassium borate. As noted in the chart supra, borates can serve as detergents, and thus can serve a dual purpose in the solution. The amount of the fire retardant may range from 0.01% to 1.5%. In another embodiment, the amount of the fire retardant may range from about 0.1% to about 1%, and in another embodiment, from about 0.1% to about 0.5%. Depending on the material being suppressed; however, there may be other variations in the amount of fire suppressant included in the solution or liquid mixture.
The solution is water soluble, and does not harden like a plasticizer, but instead can be removed as described, infra. As noted above, a major problem with traditional dust suppression techniques is the large amount of “amended water” that must be used due to the concurrent use of engineering controls such as negative air pressure differential enclosures. This negative air pressure commonly used in asbestos abatement (OSHA 29 CFR 1926.1101) and microbial remediation (ACGIH) causes many possible misting agents to evaporate too quickly. These regulations and publications call for a negative pressure differential enclosure measured with a manometer at negative 0.02 inches of water column or greater. This is equal to negative 5 pascals or greater. Generally, this means there is approximately 4 air changes per hour or greater as more air leaves the contained area than enters it. The purpose of the contained area under negative air pressure is to help prevent cross-contamination at the expense of using more water than necessary at the expense of our natural resources.
The composition and method discloses herein is “environmentally preferable” or “green” due to the significant reduction in water usage and electrical usage. First, the misting agent is a slow evaporator. Second, the work areas are contained with “critical control barriers” and necessary plastic sheeting or other material to prevent migration of contaminants outside the work area. Preferably, the work area is under “neutral” air pressure differential or between +0.02 to −0.02 inches of water column. Preferably, only the areas under negative air pressure are the decontamination chambers where workers remove waste material or their personal protective equipment before passing through the shower between the equipment room and the clean room or entrance/exit. (equipment room, shower).
There are various machines that can be used to mist or fog the air with the misting agent. It should be noted that there is a difference between the terms “misting” and “fogging”. Fogging is to produce an average micron band droplet size of generally 35-50 microns or less. Some water droplets will be below or above 50 microns but the average size of the droplets will be 50 microns in diameter. Misting is producing an average micron range for droplets above 50 microns. Either type of machine will work for misting the air for dust suppression. The fogging approach takes more time to settle since the water droplets are smaller and float more easily. Misting uses a little more liquid and the larger droplets fall more rapidly. Both types of machines require the use of respirators.
It should be noted that there must be supersaturation for the droplets to grow and combine with the particulate matter in the air. By supersaturating the atmosphere of the room to be cleaned, capture efficiency is increased, because more particles capture more particulate matter (asbestos, etc.), and thus more droplets become weighted down and fall to the floor, thereby cleaning the air.
The desired size of the water droplets is determined by a number of factors. The two principal factors are the atmospheric temperature and humidity. For instance, the above quoted 35-50 micron droplet size appears to be optimum in an atmosphere having a 40-60% relative humidity. If the droplets are too large and fall to fast, gravity overtakes the shear gradient coagulation. However, if the temperature is greater and the humidity is much lower, larger liquid particles are required, or the fogging time needs to be increased. If the droplets are too small, svocs become volatile in the air, whereas it is desired that the svocs stay bound to the water. It is also desired that the water not evaporate too quickly. Bigger droplets in such cases will be required for supersaturation. For example in the hot, dry climate of Arizona, it may be desired that the solution droplets be over 50 microns, and even over 200 microns.
Furthermore, during the misting process, temperatures outside of the normal room temperature, or temperatures outside of the 60-75 degree range can present certain problems in the removal of particulate matter in the air. The lower the temperature, the higher the vapor pressure and thus water can be held in the air. If the air temperature is too cold, the mist cannot stay in the air long enough to allow for the capture of airborne particles.
Conversely, if the temperature is too high, the vapor pressure is low, and there is so much humidity in the air and thermal movement of molecules resulting in the mist staying in the air too long to settle. The mist will take too long to capture particles and settle on a surface. In fact, the humidity in the air can combine with the mist and bring the mist down before the mist has an opportunity to capture the dust particles.
To overcome these problems, the temperature of the room is altered to optimize the humidity conditions of the room. This is accomplished by any method of temperature exchange. In wintertime or during cold weather, a heater can be used to warm up the room being treated. Other heat exchange devices can be used in addition to a heater. In hot weather, an air conditioner can be used to cool down the room to lower the humidity and thermal movement of molecules, allowing the mist to capture dust particles and then settle down on a surface, where they can be cleaned up. Any method or device can be used to optimize the temperature of the room such that the mist can successfully remove particles in the air.
The type of machines to dispense the misting agent are manufactured by Fog Master, B&G, ElectroFan, and Dramm. These types of machines can be used to mist or fog the misting agent All of the machines generally work the same way. Each fogger or mister creates enough pressure to disperse the misting agent at a small droplet size at various volumes per minute through one or more orifices, depending on motor sizes and preference.
Hand pumps that are used to dispense pesticides and herbicides that could also be used. These inexpensive devices would dispense greater amounts of the misting agent at much larger water droplet sizes with more labor which would partially offset the “green” benefits as well as reduce labor costs.
During the fogging/misting process, the fogging or misting machine is moved around the room, or at least a hose of the machine is moved around the room to maximize the area in which the solution is sprayed, allowing for an increase capture efficiency. It is to be remembered that sheer or gradient coagulation is being used, rather than thermal or kinematic coagulation. Particles flowing in a velocity gradient, even if they are the same size, will travel at different velocities because of their positions on different (but close) streamlines. This relative motion leads to collisions as particles on a faster streamline overtake those on nearby slower streamlines. Turbulent flow produces eddies that cause relative motion between particles. This relative motion can come from velocity gradients in a manner similar to that just described or by the inertial projection of particles across the eddies. This latter becomes particularly important as the scale of the fluctuations (the size of the eddies) approaches the particle stopping distance. It is thus critical that as much of the air, and the surfaces in the room, be sprayed to maximize the surface area being exposed to the droplets. Such exposure increases the possibility of capture of the particulate matter (dust, asbestos, fibers, etc.) being exposed and captured by the liquid solution. A slow sweeping motion of the hose, or of the machine, is recommended to increase the capture efficiency.
On large projects, this lack of a need for large HEPA filtered negative air machines will greatly reduce electrical usage while helping to reduce the amount of water required by 80% to 95% versus typical misting processes using other reagents or solutions. The amount of the cleaning solution used varies from project to project, but one gallon of the proposed solution should be create a cloud of water droplets that capture particles in an 80,000 cubic feet area when dispensed by a B&G fogger. The machines generate an aerosol of liquid droplets that adheres to the particulates floating in the air as the droplets descend to horizontal surfaces. This area coverage amount could be less if personnel wear motor operated air purifying respirators (PAPR) which help supply air through filters to the respirators. The PAPR respirators would filter the air next to the motor of the personnel using the PAPR equipment which would necessitate further application of the misting or wetting agent. Also, continual releases of construction material or other particulate generating activities may necessitate further misting or fogging for this solution. At any rate, the amount of product required will be far less in volume than traditional misting or fogging agents that evaporate too quickly.
Whether the initial application was performed to reach super-saturation or not will still result in the putting of these small droplets in the air as dry air infiltrates the indoor environment where fogging or misting has taken place. This infiltration of dry air lower humidity causes droplets to shrink to sizes allowing higher concentrations of irritants in the air. This problem can be solved by fogging or misting water droplets for a second treatment immediately after fogging or misting the initial mixture of water, surfactants/detergents, SVOCs and/or oils so the small droplets with higher concentrations of surfactants/detergents, SVOCs and/or oils. This causes the droplets from the first fogging or misting treatment to grow large enough to settle with gravity so the air has water vapors without the surfactants/detergents, SVOCs and/or oils.
This second step may occur anywhere from immediately after the first misting/fogging, or up to four or more hours later. This second step may even occur the next day. This step is taken to remove any residual treatment chemicals, which may act as irritants, still floating in the air. The size of the water droplet being misted or fogged will vary depending upon the amount of humidity in the air and/or the temperature of the room being treated. Some climates will be dryer and thus require larger water droplets. In more humid climates, water droplets should be smaller in size. Additionally, more water droplets would be needed in a dryer climate, and fewer water droplets will be need in a damper (or more humid) climate. Similarly, hotter temperatures will require more water droplets, and cooler temperatures will require fewer water droplets. The amount of water needed will vary depending on the size and climate of the room, but will usually be from about 25% to 100% of the original solution amount.
This also speeds the process to clean the air since on average one may have to wait 4 or more hours for the initial application of water, surfactants/detergents, SVOCs and/or oils droplets in the air to settle with gravity. The addition of the second step of water fogging/misting increases job and worker efficiency since there is less down time. It also reduces the safety equipment or personal protection equipment since the air is more clean and the skin has less exposure to irritating or hazardous chemicals or particulates, and the room will be healthier for future occupants.
This follow up water fogging/misting step can be used in any other means of aerial treatment for any aerosol application of a room, or enclosed space. This water fogging/misting step may be used as a follow up step where there has been the application of antimicrobials, insecticides, air fragrance/deodorizers products or dust suppression products to clean the air or applied via the air to surfaces.
The size of the water droplet should be similar in size to the droplet size in the first misting step. That size should be from about 35 micrometers or larger, or at least large enough to settle reasonably quickly.
The water solution used in the second step may be 100% water, or may contain ethanol or other alcohols, in varying amounts, which may assist in capturing polar and nonpolar contaminants.
As the mist removes the particulate material from the air, the particulate material settles on surfaces. The settled particulate material is then removed by HEPA vacuuming, damp-wiping or using a dry cloth with a cationic charge (static cloth). For definitional purposes, the HEPA filter is a high efficiency particulate air filter that can capture particles down to 0.3 microns at a capture rate of 99.97 percent. Some HEPA filters are now even more sensitive. Damp wiping can be done with natural or synthetic fiber based cloths that are damp with any liquid including the misting or fogging agent. The damp wipe cloths can be disposed as waste material or laundered depending on the target agent removed from the air and surfaces.
Tests have been performed to determine the capabilities of the misting agent and process in removing asbestos and soot.
In the first test, Limpet (brand name) asbestos was removed from ducting in a high-rise condominium building. Limpet is a thermal surface insulation (TSI) comprised of 60-80% amosite, 2-5% chrysotile and 1-2% crocidolite. The material is very friable and resembles grey Rockwool insulation in appearance. It is wet applied with glue-like substance for adhesion. Amosite is known to repel water and crocidolite is known to be chemically resistant.
A 3 stage decontamination chamber including a shower in the middle stage was constructed. A negative air pressure machine was connected to the equipment room or dirty room so this room and the shower would be under negative air pressure. The work area was not under a negative air pressure differential. The building material in question was removed while a licensed industrial hygiene firm tested the air outside the whole containment system to ensure no cross-contamination. A personal air monitoring pump with a cassette was worn to collect an air sample of the immediate breathing space.
Fiber counts were purposely driven to high levels even though wet methods were used to remove the asbestos to determine if very high levels of asbestos could be removed from the air without the benefit of negative air pressure containment in the work area where asbestos was removed.
The personal air samples were so overloaded only a transmission electron microscope could read the samples. The lowest result for personal air samples was over 1,000 structures per square millimeter. (OSHA recommends not exceeding a level greater than 1 cubic centimeter of asbestos fibers in a phase contrast microscopy sample with a light microscope.
The post test results were extremely low (nothing detected, 1 structure detected and 2 structures detected). Normally, OSHA recommends 70 structures per square millimeter or less as acceptable. There was no cross-contamination detected by the industrial hygienist using phase contrast microscopy air samples read onsite by with a light microscope. A misting agent comprised of a solution of phenol, sodium phenate, sodium borate, sodium dodecylbenzene sulfonate, glycerol and water as the was used to clean the air in the containment.
To test for soot, a containment test chamber (8 feet by 10 feet with an 8 foot high ceiling) room was built from plastic and PVC poles with connectors. There was a single flap door on the side away from the wind to prevent cross-contamination or air clean air dilution of the test chamber. Exhaust was ducted with an inline fan pulling smoke from a fireplace burning wood charcoal, newspaper and motor oil. The oil was used to produce black smoke or soot (black carbon). The particles were uniform in size from 25 to 30 nanometers. Approximately 8 ounces of motor oil were burned, by pouring it over a folded newspaper on charcoal in the fireplace. Initially, effectiveness of soot removal was checked by taking air samples at 10 liters per minute for a set for 5 minutes before fogging the solutions, 2 hours after fogging the solutions and 4 hours after fogging the solutions. A determination was made as to how long to fog in the given area of the containment (1 minute, 3 minutes and 5 minutes), with 5 minutes proving to be the best time for effectiveness. All tests were performed in temperatures from 65 to 78 degrees Fahrenheit and relative humidity levels from 20 to 75% with average wind speeds not to exceed 15 miles per hour according to data available from various sources.
A 25 millimeter cassette with a mixed cellulose ester (MCE) with a pore size of 0.45 microns was used for testing. This cassette is normally used for asbestos sampling to be read by transmission electron microscopy (TEM). The samples were read with a light microscope magnified further by attaching a digital camera with a 10.times. lens coupler viewed on a television monitor. Images were easily viewed at 2,000.times. and see particles as small as 0.3 microns or 300 nanometers. A piece of cellophane tape (approximately 4 mm by 4 mm) was applied on the 25 mm MCE filter before sampling to get a visual comparison of clean MCE filter area versus soot filled areas near the tape location.
Comparison sampling was performed after filing the containment with smoke largely containing soot or black carbon (95%) of the sample. Sampling at the same time intervals previously listed was performed, along with a 30 minutes sample 4 hour after the filling of the chamber with smoke was stopped. Sampling continued for the every 30 minutes. The same process was performed for fogging with the misting agent (comprising the concentrated phenolic solution (phenol (1.6%), sodium phenate (0.6%), sodium borate, sodium dodecylbenzene sulfonate, glycerol and water), with the misting agent at 20% dilution, at a 10% dilution, just water and water with a quaternary ammonium surfactant. Samples indicated the water with surfactant was worse than water by itself. Water by itself was only moderately more effective than doing nothing.
The chamber reached a level of cleanliness (little to no observable particles) in air samples by using the full strength phenolic solution when the relative humidity was 70% or higher. Determination of cleanliness was made by reading the MCE filters using light microscopy. Success was achieved with a relative humidity of 50% with a 20% phenolic solution. The fogging time had to be doubled to 10 minutes with a 10% phenolic solution when the relative humidity was 20%. The average water droplet size applied by the B&G cold fogger machine was 35 to 50 microns.
A “before” and “4 hours after fogging” sample was sent to EMSL in New Jersey for confirmation by using the same type of cassette with additional polycarbonate filter with pores of 0.1 microns. The samples were taken at 12.5 liters per minute. The “before” sample was run for 30 minutes or 375 total liters of air. The “4 hours after fogging” sample was run for 2 hours or 1,500 liters. The samples were read for combustion byproducts with an electron microscope using different methods. The lab indicates the “before” sample was over loaded WITH 10 times more material than the “4 hours after fogging” sample.
The particles were uniform measuring 25-30 nanometers. This means that there was an approximate 90% reduction of the absolute hardest particle to remove via dust suppression since soot or black carbon is generally a combustion byproduct of hydrocarbons. These particles behave more like gas than particles according to many sources. They generally avoid water droplets by Brownian movement. This is the reason wet scrubber technology used a venturi design to mist combustion exhaust in pollution control. Additionally he 5 minutes of fogging time only used 37.5 ounces of the phenolic solution at each dilution in the 640 cubic foot containment. Samples were maintain for comparison of the different solutions.
