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 ...

Bird Control in New Construction Sites

When excavating a construction site you’re bound to come across numerous obstacles. While each one has its own level of difficulty to overcome, arguably the hardest to conquer is relocating wildlife from the site. Today we’re featuring a guest article from Emily Matlovich, writer for CADdetails’ blog ...

Methods of Purification by Water Innovations, Inc.

Carbon Filtration is used for several reasons. Its primary purpose is the reduction of chlorine to less than 0.1 ppm. Chorine can damage softener resins, reverse osmosis membranes, and mixed bed deionization resins. Activated carbon will also help control tastes and odors, provide organic and hazardous organic chemical reduction, and some particulate reduction. ...

Human Error Threatens Safety in Hazardous Areas

The top 5 problems identified in hazardous areas are Poor or no maintenance on flameproof (Ex d) enclosures. Due to corrosion—especially when equipment is installed outdoors—the Ex d protection is gone 2-3 years after installation. Incorrectly installed Ex d cable glands. Even if the combination of cable and gland is chosen correctly, the instructions on how to ...

Water management solutions minimize flood damage

Human societies around the world have used timber as a building material for thousands of years. As wood is the only significant biological building material we are naturally inclined to believe that using wood in construction is good for the environment. As a matter of fact the environmental benefits of using timber are not straightforward: although it is a natural product, a large amount of ...

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 ...

Flammable Hazards

Flammable Hazards The difference between a gas and a vapor is that vapors arise from liquids, whereas gases are normally in a gaseous state. Flammable vapors present additional sampling concerns (for example, we must prevent vapors from returning to the liquid state during sampling). The 3 Elements of Fire Three elements must be present for a flammable ...

Area Monitoring: Diffusion Sampling

Indoor and outdoor gas hazards that exist in open areas are usually monitored using diffusion-type sensors. A diffusion sensor has no active sample-drawing system; diffusion sensors rely on the ambient air movement and pressure to deliver the sample to the sensing element. Diffusion-type sensors are a reliable and cost-effective way to monitor open area gas hazards. When installing diffusion ...

MEGATRENDS influencing rural areas

At the time we have several worldwide mega trends – maybe more mega problems – like: CO² increase and climate change (increase of the avg. temperature of 1° in 100 years), population growth (1960–2043 from 3 to 9 Bio people, in 250 years from 1 to 10) and urbanization (in 2030 60% of the population will live in urban areas), bio energy versus food and food ...

Comparison of hazard area and casualty predictions of a small-scale chemical attack using various toxic load toxicity models

It has been observed that the toxic load model can better account for toxic effects from chemical exposures than Haber’s law. However, the toxic load model has been experimentally validated only for steady exposures. We compare four proposed extensions of the toxic load model to the case of time-varying exposures. We conclude that the choice of the toxic load model can be important in ...

Potential use of transport and dispersion model output to supplement Allied Tactical Publication–45 hazard area prediction templates

Allied Tactical Publication–45(C) is the current US and NATO command doctrine for Nuclear, Chemical and Biological (NBC) events. ATP–45 is designed to warn military populations of NBC hazard by providing area–warning templates based on NBC messages. ATP–45 is designed to produce a single 2–hour hazard area template that accounts for wind speed fluctuations, but it ...

Flood hazard maps

Flood hazard maps have to be developed for areas, which have been identified in the preliminary flood risk assessment. For certain flood frequencies the extent and the water depth, the flow velocity or the relevant water flow have to be mapped. Flood frequencies consider (2007/60/EC): floods with a low probability, or extreme event ...

The Area Source Mact/Gact Challenge

Dozens of new federal rules, regulating over 180 Hazardous Air Pollutants for relatively small sources, present a new and unique challenge for the air pollution profession. Over the past two decades, a large number of federal regulations have been adopted to control Hazardous Air Pollutants (HAPs) originating from a wide range of source categories from the corner dry cleaner to petroleum ...

Nanotechnology – what is it? are there hazards?

This is the first of a series articles on the emerging field of Nanotechnology. What is it? In short – small! Very small! Very, very small! Nanotechnology comes from the prefix Nano which, in English, means 1/billionth, just as micro means 1/millionth. So Nanotechnology involves 2 things: 1) extremely small man-made materials – some even as small as 1 atom thick, ...

Management of Hazardous Wastes

' Management of hazardous waste is a growing concern in many countries. The long-term impacts and costs of improper disposal can be very high and the emphasis must be on prevention. A comprehensive management system should include (i) policies, institutions and effective regulations and (ii) adequate and acceptable disposal facilities (either public or private). This note outlines the key ...
