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. Solidifying liquid or gel contaminants can enhance their physical removal. Another way to test the effectiveness of decontamination procedures is to analyze for contaminants left in the cleaning solutions. Properly stowing the AAL, accessories and mask. delayed until past the time of bone marrow suppression and delayed wound healing. 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.

DECONTAMINATION GUIDANCE FOR CHEMICAL INCIDENTS The Primary Response Incident Scene Management (PRISM) series was written to provide authoritative, evidence-based guidance on mass patient disrobe and decontamination during a chemical incident. Sodium nitrite can increase methemoglobin levels, which will decrease blood oxygenation. 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.

Separate flow patterns and stations should be provided to isolate workers from different contamination zones containing incompatible wastes. Chest x-rays reveal a widened mediastinum and the patient?s white blood cell count is elevated. If contaminants that have permeated a material are not removed by decontamination, they may continue to permeate to either surface of the material where they can cause an unexpected exposure. 11.
