Crime Scene Cleanup >> How To Clean Up Fingerprint Dusting Powder

Sandi's decontamination foam, developed more than a decade ago for remediation of chemical and biological agents and used to decontaminate federal office buildings and mailrooms during the anthrax attacks in 2001, How To Clean Up Fingerprint Dusting Powder is now being used to decontaminate illegal methamphetamine labs. 

Researcher Mark Tucker (6632) demonstrates application of Sandia-developed decontamination foam. How To Clean Up Fingerprint Dusting Powder The foam, used 10 years ago in the cleanup effort following the deadly 2001 anthrax attacks, is now being used to decontaminate environmentally devastating meth labs. 

Mark Tucker (6632), a chemical engineer in Sandi's Chemical & Biological Systems Dept. and co-creator of the original decontamination formulas,How To Clean Up Fingerprint Dusting Powder DF100 and DF200, says the decontamination formulation renders all types of typical chemical and biological agents harmless. 

"For structures contaminated with meth, owners have two choices: demolish it or reclaim it,"says Kevin Irvine, vice president and general manager at EFT Holdings, which licenses the Sandia formulation and sells it under two names, EasyDecon® DF200, certified against chemical and biological agents, and Crystal Clean, intended for meth cleanup. How To Clean Up Fingerprint Dusting Powder The meth cleanup problem is a big one. 

The US Drug Enforcement Administration's (DEA) Clandestine Meth Lab registry lists thousands of locations in the US where law enforcement agencies have reportedly found chemicals or How To Clean Up Fingerprint Dusting Powder paraphernalia indicating the presence of either clandestine drug laboratories or dumpsites. 

In 2007, EFT released Crystal Clean, a chemically identical formula to EasyDecon® DF200, but packaged and marketed specifically for meth cleanup. How To Clean Up Fingerprint Dusting Powder Sites contaminated with meth are considered crime scenes, but the contamination is chemical rather than biological.

So the approximately 700 remediation companies that clean up meth lab contamination also do other types of crime scene cleanup because they are accustomed to the sampling and documentation process. How To Clean Up Fingerprint Dusting Powder Holding the bag "Property owners are often liable for expensive cleanup costs since most insurance companies won't pay for cleanup related to methamphetamine.

Viewing damage resulting from meth labs as arising from a criminal act,"Irvine says. How To Clean Up Fingerprint Dusting Powder That means that property owners and landlords are often left holding the bag for the cost of remediating a residence or business contaminated as a result of meth cooking." 

According to the Department of Justice, the chemicals used to cook meth, and the toxic compounds and byproducts resulting from its manufacture, produce toxic fumes, vapors, and residues. How To Clean Up Fingerprint Dusting Powder The report says anyone, but especially children, spending time in or near a meth lab could be exposed to toxic substances, which could produce short- and long-term problems. 

Chronic exposure to substances typically used in meth manufacture may cause cancer; damage the brain, liver, kidney, spleen, and immunologic system; and result in birth defects. How To Clean Up Fingerprint Dusting Powder Mark says many cleaning methods don't remove methamphetamine and the chemicals used to produce it. 

Incompletely or improperly cleaned surfaces, such as floors, countertops, and drywall, can remain contaminated, even after being cleaned many times. Methamphetamine can remain in a structure for months to years. How To Clean Up Fingerprint Dusting Powder Mild, nontoxic, noncorrosive. 

The decontamination formulation includes a collection of mild, nontoxic, and noncorrosive chemicals found in common household products, such as hair conditioner and toothpaste. How To Clean Up Fingerprint Dusting Powder It contains both surfactants, which lift agents off a surface, and mild oxidizers, which break down the agent's molecules into nontoxic pieces that can be washed down a household drain like detergent or dish soap. 

In experiments from a few years ago, John Martyny, associate professor and industrial hygienist at the National Jewish Medical and Research Center's Division of Environmental and How To Clean Up Fingerprint Dusting Powder Occupational Health Sciences and a national expert on the effects of meth exposure on children, compared the effectiveness of common cleaners, such as detergent and bleach, on methamphetamine cleanup. 

Martyny included Sandi's decontamination formula in the testing. How To Clean Up Fingerprint Dusting Powder His experiments showed that, after cleaning with EasyDecon, the methamphetamine present on tested surfaces was likely oxidized to another compound and was nondetectable. Irvine says even if a meth site is known, it doesn't always mean it gets cleaned up, due to the expense. 

Some states don't have cleanup guidelines and don't require homeowners to disclose if a structure is contaminated with meth. How To Clean Up Fingerprint Dusting Powder There have been instances where families have discovered they were living in a house contaminated with meth only after family members were hospitalized for respiratory problems characteristic of chronic meth exposure. 

In the 22 states that have guidelines, structures contaminated with meth are seized by police, How To Clean Up Fingerprint Dusting Powder and the structure is quarantined by a local or state agency (depending on the state) until it can be demonstrated that the structure is cleared of methamphetamine to a certain level. 

During structure remediation with Crystal Clean, a remediation crew removes everything from the structure, including carpets and drapes, until the house is stripped bare except for the fixtures. How To Clean Up Fingerprint Dusting Powder The crew mixes the Crystal Clean solution on site and sprays the foam on walls, ceilings, and floors. 

The foam expands to about 15 times its liquid volume through a special nozzle that draws air into the spray, allowing it to reach contamination in crevices and in the air. How To Clean Up Fingerprint Dusting Powder In an hour, it collapses back to a liquid. Using only fresh water, rags, and sponges, the crew then removes the benign residue from all surfaces. 

After the site is cleaned, an independent industrial hygienist tapes off a sample area in the cleaned structure and takes a number of swipe samples appropriate for the location size. How To Clean Up Fingerprint Dusting Powder The samples are treated as evidence, so a formal chain of custody is established for the samples, and they are taken to an independent lab. 

The lab runs the samples through a mass spectrometer to determine the level of contamination. How To Clean Up Fingerprint Dusting Powder In most instances, Crystal Clean reduces the levels from a pre-test state, to .02 μg/100 square cm (microgram/sq. cm) or less, which is considered nondetectable. 

Irvine says the Crystal Clean formula is more expensive than other cleaners, but that the product saves greatly on labor costs and lab costs because other cleaning solutions usually require more than one cleaning, with a larger crew doing the cleaning, How To Clean Up Fingerprint Dusting Powder and with costly sampling taking place in between cleanings. 

Another advantage of this cleanup method, Irvine says, is that some other methods are destructive or use more corrosive substances, and the resulting chemical residues are themselves toxic. How To Clean Up Fingerprint Dusting Powder Crystal Clean is rendered nonhazardous and nontoxic, requiring only a surface wipe when finished. 

Sandi's decontamination formula was developed through funding provided by the DOE and NNSA Chemical and Biological National Security Program (CBNP). How To Clean Up Fingerprint Dusting Powder Sandia has also licensed the DF200 formula to other firms, which have developed it for use in a wide-ranging variety of applications, such as commercial and residential mold remediation.

Disinfection of hospitals and schools, pesticide removal for farm equipment, and military applications, including counter terrorism preparedness. How To Clean Up Fingerprint Dusting Powder The foam has also been deployed as a preventive measure at presidential debates and a political convention.
