This article presents a standard operating procedure for crime scene and identification processing of illicit methamphetamine laboratories.
Abstract
Investigation of such laboratories entails special problems. Exposure to sizeable quantities of methamphetamine can result in contamination of the examination room, powder jar, brushes, dusting kit, and clothing worn by those examining for latent fingerprints. The odor associated with the production of the drug permeates clothing and equipment. In addition, problems such as high blood pressure, fast pulse rate, and excessive sweating may be experienced by investigators. Consequently, it is necessary that fully encapsulated body suits and self-contained breathing equipment be used by personnel. Criminalists should be trained in the use of this equipment, and no more than 2 hours should be spent using it. Blood pressure of criminalists should be checked on entering and before leaving the scene, and criminalists should not use more than three tanks of air during scene processing. Special precautions also are needed in dealing with the evidence. Latents should be individually sealed in clear plastic to prevent possible contamination. An underwater camera or one committed to investigation of laboratories should be used, and all hazardous chemicals or solvents should be secured prior to using an electronic flash to avoid accidental ignition of volatile vapors.
