For example, contaminants such as glues, cements, resins, and muds have much greater adhesive properties than elemental mercury and consequently, are difficult to remove by physical means. Physical removal methods for gross contaminants include scraping, brushing, and wiping.
Decontamination - the process of removing or neutralizing contaminants that have accumulated on personnel and equipment - is critical to health and safety at hazardous waste sites. Decontamination protects workers from hazardous substances that may contaminate and eventually permeate the protective clothing, respiratory equipment, tools, vehicles, and other equipment used on site; it protects all site personnel by minimizing the transfer of harmful materials into clean areas; it helps prevent mixing of incompatible chemicals; and it protects the community by preventing uncontrolled transportation of contaminants from the site.
While decontamination is performed to protect health and safety, it can pose hazards under certain circumstances. Decontamination methods may: Be incompatible with the hazardous substances being removed (Le., a decontamination method may react with contaminants to produce an explosion, heat, or toxic products).
All equipment used for decontamination must be decontaminated and/or disposed of properly. Buckets, brushes, clothing, tools, and other contaminated equipment should be collected, placed in containers, and labeled. Also, all spent solutions and wash water should be collected and disposed of properly.
All personnel, clothing, equipment, and samples leaving the contaminated area of a site (generally referred to as the Exclusion Zone) must be decontaminated to remove any harmful chemicals or infectious organisms that may have adhered to them.
The mechanisms of solidification are: (1) moisture removal through the use of absorbents such as grounded clay or powdered lime: (2) chemical reactions via polymerization catalysts and chemical reagents; and (3) freezing using ice water.
Segregation at the drop reduces the probability of cross-contamination.
