Meth Lab Cleanup >> Chemicals Used In Meth Labs

Another meth cooking method that is not that common, but can be found is the Amalgam or P2P method,which primarily uses phenyl-2-propanone (P2P) and methylamine along with lead acetate and mercuricchloride. Other chemicals used in this method include Chemicals Used In Meth Labs aluminum, hydrochloric acid, isopropyl alcohol,methanol, ethanol, acetone, benzene, chloroform and ether. Elevated levels of lead and mercury can bepresent following this type of lab.
 
The "cooking" of meth can involve a large variety of chemical reagents depending on the specific methodof manufacture. In general, the process involves precursor reagents, organic solvents, and reactivereagents that facilitate the conversion of the precursor into meth. The Chemicals Used In Meth Labs chemicals used are typicallypurchased, stolen, or illegally manufactured. Even though many of these chemicals are commonly foundin households and can be "safe" if used appropriately, their inherent dangers are exacerbated when usedinappropriately or in combination with other chemicals during the meth production process. Improperstorage and disposal of these chemicals and mixtures also creates hazards.
 
Exposures and health concerns are greatest during the cooking processes. The levels of airbornechemicals vary greatly with the different cooking methods, the specific chemicals used, and the Chemicals Used In Meth Labs scale ofthe production, the size of the room or structure, and the ventilation of the cooking area. Generalconcerns include the risk of fires or explosions due to usage of flammable solvents, respiratory difficultiesfrom breathing toxic or corrosive vapors, and skin irritations from strongly acidic and basic solutions.
 
Chronic exposure to meth production may cause long-term health problems. Drug paraphernalia such asneedles present possible exposure to infectious agents such as HIV and Hepatitis B and other bloodborne pathogens. After the cooking Chemicals Used In Meth Labs process has stopped, most of the hazards decrease. In addition, proper removalof the production wastes and bulk chemical supplies eliminates many of the risks associated withclandestine meth labs. Volatile chemicals and solvents such as ammonia, methanol, ether, or acetonewill move into air and will be readily removed from the structure by ventilation.
 
However, some residual contamination created from repeated "cooks" can persist long after allproduction has ceased. Semi- or non-volatile production chemicals such as acids, bases, and othercorrosives, precursor chemicals, Chemicals Used In Meth Labs and products used or created in the manufacturing processes are morepersistent. These residual chemicals can be volatilized or aerosolized during the cooking process anddeposit on surfaces and in materials (such as carpeting, fabrics, and building structure materials).
 
Meth can be found on most surfaces, building materials, and home furnishings of a clandestine lab. Research done by National Jewish Hospital suggest that re-volatilization of meth may Chemicals Used In Meth Labs occur after theinitial deposition. Meth and other fine particle contaminates can be aerosolized and dispersed throughoutthe former lab. Refer to Table A, Meth Production Chemicals Present in Active and Former Meth Labs (below) forcomparison of active meth lab dangers to residual contaminants remaining after meth production ceases. Regarding Table A:
 
• The former meth lab environment is much less hazardous than the active lab environment. Asindicated in the last column, the solvents have dissipated and the reactive materials have Chemicals Used In Meth Labs beenmostly reduced or depleted; existence of either is far less in the former meth lab than in an activemeth lab.
 
• Not all the chemicals listed in Table A will be found in every meth lab. Reaction materials useddepend upon the Chemicals Used In Meth Labs method of production. The solvent(s) used in each cooking process may varydue to availability, cook's preference, etc.

Surface Wipe Sampling Procedure
Wipe sampling is performed to establish the presence of meth on non-porous surfaces. Samples shall betaken using methanol-dampened wipes. Wipe material can be sterile filters, gauze Chemicals Used In Meth Labs pads or swabs andcan be obtained pre-prepared from an environmental laboratory.Water-dampened wipes shall not be approved by this guidance due to the lack of meth capture by waterdampened samples. The sampler shall have clean hands and shall wear gloves during each samplingevent to prevent the introduction of contamination or cross contaminating sample areas.
 
 The sampling area shall be a relatively dry surface. Post-decontamination wipe sampling shall be performed afterwashing and painting or sealing of walls and surfaces. Procedure includes:
1. Sampler dons a clean pair of latex or other chemically-protective gloves.
2. Sampler attaches 10 centimeter (cm) by 10 cm template or measures with a ruler and marks byusing tape a pre-designated Chemicals Used In Meth Labs sampling location or area. (Sampler shall avoid touching the areawithin tape/template as to not disturb sampling area.) The sampler can either mark one sample ata time, or mark off all areas to be sampled within the structure at once. Photograph sample siteswith an identifying reference point.
 
3. Sampler dons a clean pair of gloves Chemicals Used In Meth Labs to begin sampling.
4. Either soak the sampling wipe (filter or gauze pad) with 2 mL methanol or take the wipe out of apre-soaked container. Use dampened wipe within 5 seconds of applying methanol to ensure that the wipe is damp. A dry wipe shall not capture a representative meth sample.
 
5. Applying firm pressure, wipe the surface area within the template/taped area by starting at theoutside Chemicals Used In Meth Labs edge working towards the center of the surface area by wiping in concentric squares ofdecreasing size until the area inside the template has been wiped. Avoid wiping the marking tapeor template. Fold the wipe so the sampled side is folded in.
 
6. Insert the wipe into the sample jar and close the lid tightly.
7. Record the exact location, including the room and the approximate height (from the floor), dateand time of the sample Chemicals Used In Meth Labs on the sample container, the chain of custody form and sampling notebook.
8. Properly dispose of gloves and marking tape and proceed to the next sampling location.
