Many hazardous chemicals are commonly used in drycleaning shops to remove garment stains. Workers performing stain removal may be exposed to these toxic chemicals through skin absorption, eye contact, or inhalation of vapors. The primary hazard is dermatitis from chronic or acute exposure. Dilute hydrofluoric acid, found in some products that remove rust stains, may cause severe chemical burns ...

PROBLEM/CONDITION Although they are infrequent, acute chemical incidents (i.e., uncontrolled or illegal release or threatened release of hazardous substances lasting <72 hours) with mass casualties or extraordinary levels of damage or disruption severely affecting the population, infrastructure, environment, and economy occur, and thousands of less damaging chemical incidents occur annually. Su...

o protect personnel from hazardous materials, substances must be unambiguously detected in real time. This goal is being pursued with the application of a wide range of technologies. Most chemical sensors must strike a compromise between sensitivity and selectivity to meet the real-time goal. The sensor platform described in this article is designed to eliminate any such compromise. Thus far, w...

To solve the uncertainty and complexity problems in hazardous chemical storage risk assessment, this paper constructs the evaluation index system and proposed the risk assessment model based on AHP-fuzzy comprehensive evaluation approach, which organically integrate the quantitative and the objectively of the analytic hierarchy process (AHP) and the inclusive advantage of fuzzy comprehensive ev...

The purpose of this research is to develop a universal model with a practical system to evaluate, identify and select an optimal system or device to perform the desired task from a large collection of available systems that have multiple objectives based on a fuzzy multiple criteria decision making model (FMCDMM). As an example, here we are using this research to identify and select an optimal ...
