  • Hazardous waste and not, Baioni-Dicatech system

    The identification, characterization and restoration of contaminated areas now represent a big environmental issue, both at European and national level. In the major industrialized countries the issue of contaminated land has come out in all its gravity in the late seventies when, against a widespread awakening of environmental consciousness, important pollutions events emerged. Consequently, in ...

  • New Chemical hazards in the workplace

    In the days when Industrial Hygiene became a recognized scientific discipline, smoke stacks belched black smoke in River Rouge, MI and Pittsburgh, PA. Men worked in clouds of coal and asbestos dust and labor was hard, physical and usually dangerous. Personal protective equipment was rare; its use, even rarer and its protective effect marginal. Today, the face of manufacturing has changed ...

  • Hazardous chemicals and proper storage solutions

    Many acceptable categorical storage schemes have been proposed and used by laboratories in academic, industrial, government and medical institutions. The common features uniting all these plans is the separation of incompatible materials. The differences in these various storage schemes arises in the number of groups that should be established for segregation purposes. The ten most commonly cited ...

  • Maintenance To-Do: Coil Cleaning

    A coil-cleaning program should be an integral part of maintaining some kinds of process cooling equipment. Most people think of coil cleaning as a building or facility prepares to turn on the air-conditioners for another season. Admittedly, spring is a perfect time to put such cleaning and maintenance at the top of the to-do list. Condenser and evaporator coils are an integral part of HVAC ...

  • Study on Hazardous Household Waste with a main Emphasis on Hazardous Chemicals

    Introduction The aim of this study is to evaluate national experiences of the management of hazardous products likely to become hazardous household waste (HHW), and to make proposals for strategies for the appropriate management of such products within a lifecycle perspective. The study covers the fifteen Member States and two Accession Countries, namely Hungary and Romania. The data available at ...

  • Salinity changes impact of hazardous chemicals in Enchytraeus albidus

    Supra‐littoral ecosystems are among the most challenging environments for soil organisms, particularly when facing salinity fluctuations frequently combined with the presence of contaminants as a result of intense anthropogenic activities. Knowledge of how salinity influences the effect of contaminants in supra‐littoral species is crucial for determining the safety factors required when ...

  • Hazardous Location LEDs in Chemical Manufacturing Facilities

    Employees inside chemical manufacturing plants are exposed to some of the most unforgiving work conditions in the industrial sector. This is because in such environments, workers are exposed to extreme temperatures, dust, volatile chemicals and invisible, explosive gases. Common protection methods against explosive risks include containment, segregation and prevention. Out of all the ...

  • Hazard Standards

    The Occupational Safety and Health Administration (OSHA) proposed on Sept. 30, 2009, to align the Hazard Communication Standard (HCS) with provisions of the United Nations Globally Harmonized System of Classification and Labeling of Chemicals (GHS). The HCS requires chemical manufacturers and importers to evaluate chemical hazards and provide information to subsequent users. The standard now ...

  • Petro-chemical processor meets national emission standards for hazardous air pollutants

    A multitude of chemical and petroleum processing facilities across the country are now faced with having to meet new National Emission Standards for Miscellaneous Organic Chemical Manufacturing. One specific NESHAP is 40 CFR part 63, subpart FFFF. The applicability of meeting this NESHAP is: A facility must be a major source of HAP emissions Process units that: Produce organic chemicals that are ...

  • Chemical storage buildings isolate hazardous liquids and minimize damage from spills

    The improper storage of corrosives and flammable liquids is the leading cause of spills that can result in damage to facilities and impact worker safety. One of the most effective practices to help minimize damage from chemical spills is to isolate the various chemical hazards. Since knowledge of chemical compatibility is critical, it is important to understand that there are two major types of ...

  • Development of algal interspecies correlation estimation (ICE) models for chemical hazard assessment

    Web‐ICE (Web‐based Interspecies Correlation Estimation) is an application developed to predict the acute toxicity of a chemical from one species to another taxon. ICE models use the acute toxicity value for a surrogate species to predict effect values for other species, thus potentially filling in data gaps for a variety of environmental assessment purposes. Web‐ICE has historically been ...

  • Risk–based land use planning around hazardous chemical installations

    This paper presents a framework for supporting land use planning decisions around hazardous chemical facilities taking risk into consideration. The proposed methodology contains all the steps that a planner needs to fully define the problem based on multi–criteria decision analysis (MCDA) and incorporating the needs of major local stakeholders. The decision is supported by the generation of the ...
