Classifying Hazardous Areas

The IEC is composed of approximately 40 countries including the United States. The purpose of the IEC is to establish standards for a wide variety of electrical products with the intent of encouraging international trade. The IEC has assigned a technical committee, TC 31, to develop recommendations covering equipment, testing procedures and classification standards for areas where the potential ...

Chemical Engineering Magazine: Odor Issues and Solutions for Wastewater Treatment

Today, there has been a dramatic increase in the number of industrial operations that are located within or near small towns and even large cities. When local residents constantly smell these industrial processes – particularly from wastewater treatment — unhappy neighborhoods are generally the result. In addition, many wastewater facilities can no longer produce odors without facing ...

Treating Your Water with a Biological Filtration System

Poor-quality drinking water can be an enormous hazard to your health. News stories in recent years have reported experiences of unfortunate individuals who have unknowingly consumed tainted or otherwise unsafe drinking water that included high levels of lead, calcium, arsenic, and other chemicals that have serious negative health effects. Before you take another sip of your water supply, consider ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

How to Assess Fall Hazards

Fall hazards are an ongoing concern in most workplaces and include both falls from heights as well as falls from the same level. Slips, trip and falls from both categories consistently rank among the top causes of both disabling injuries and deaths in all types of workplaces, from construction sites, to manufacturing operations to warehouses to offices. In fact, the only other category of ...

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 ...

Safety and hazards in CCS projects

Carbon capture and storage is now on the technological tipping point – it has reached critical mass with one large-scale, fully integrated power project now almost operational at the SaskPower Boundary Dam project in Canada, using enhanced oil recovery. In the UK, following the announcements of progress at two projects, Peterhead and White Rose, the government’s competition process ...

Frostbite And Hypothermia Hazards

Hypothermia and frostbite can be two of the serious consequences of working outdoors in winter weather. Hypothermia is a dangerous lowering of the body’s temperature by exposure to cold or wet conditions. Actually, the air temperature doesn’t have to be particularly low to cause hypothermia – just getting wet and chilled can do the same thing. Hypothermia can be fatal. ...

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 ...
