To the untrained person Jarrett Allen Jersey , sustainability sounds a lot like going back to an industry-free time in the stone ages and giving up everything modern and relevant to the times. On the contrary sustainability has everything to do with the times we live in. The elements of sustainability are all very clear indicators of this simple fact.

For instance, based on the Parson’s approach, sustainability means integrating renewable resources and alternative energy, and reducing individual and industrial carbon footprint. It stands for creating opportunities for local workers and suppliers for a more inclusive workforce and promoting long-term viability and economic benefits.

According to the Stanford ideology of sustainability, a sustainable ecosystem relies on four elements: productivity Jahlil Okafor Jersey , diversity, resilience and disturbance. Together, these elements determine the level of resources that can be taken from any given environment and maintained sustainably.

Let’s take a longer look at these four elements. Productivity is the growth rate of each living part of an ecosystem: animals, plants and other organisms in relation to the non-living elements of that environment. Productivity affects the level of resources an ecosystem can provide. Diversity is the number of habitats and the kinds of organisms, which influence productivity in terms of variety. Diverse ecosystems use their resources efficiently because of the nature of different species that use the same resources differently. Disturbances like storms Dzanan Musa Jersey , earthquakes, volcanoes and other occurrences that negatively affect an ecosystem can often increase productivity, to a degree, since most ecosystems balance disturbance with re-growth. Resilience is an ecosystem’s ability to recover from disturbance.
For instance, a forest fire is often thought of as purely a destructive force. Contrarily Drazen Petrovic Jersey , what it does to its ecosystem is destroys an already dead brush in order to naturally make way for re-growth and rejuvenation. It also returns necessary minerals to the soil and make the new vegetation accessible to smaller herbivores.

Sustainability is often described as a three-legged stool, with each of the legs standing for one of the E’s of sustainability: economy, ecology and equity. The three E’s are interconnected, hard to separate and often compete with each other, which could threaten the equilibrium necessary to sustain a community. Most successfully sustained communities are those that can provide opportunities to balance these three elements.

We often think of the work ‘community’ as something that relates primarily to people; a smaller unit of people bound by geography DeMarre Carroll Jersey , culture or faith. As a result, we think of sustainability as something more local, more controlled and connected to our immediate lives and surroundings. In truth, a community involves people, places Caris LeVert Jersey , other living organisms, the surrounding ecosystem, beliefs, customs and several other aspects. This means that sustainability includes addressing issues of income inequality, poverty Allen Crabbe Jersey , discrimination, climate change, clean and equitable energy, equitable access to food for all, equal suffrage rights D'Angelo Russell Nets Jersey , and equal access to food for all… It’s clear that the scope of sustainability is as large and diverse as the planet we live on.
The ATEX directive coordinates various technical and legal conditions throughout Europe to ensure a high level of safety for the end-user by reducing the explosion risk through established design methods. ATEX (ATmosphères EXplosibles) is a conglomeration of European Union (EU) directives outlining equipment installed and operated in potentially explosive atmospheres.

Since July 1, 2003, equipment manufactured for operation in potentially explosive environments has been required to comply with the EU’s ATEX Manufacturer’s Directive (949EC). The ATEX Directive applies to all countries in the EU and the European Economic Area (EEA).

The ATEX Directive places the burden directly on the end-user. The end-user is responsible for the following:

• Prevention of the formation of explosive atmospheres and possible ignition threats
• Evaluating the risk of explosion for their specific atmosphere and process
• Eliminating or reducing the level of risk for a specific atmosphere andor process
• Classifying the work and equipment environment into “zonescategories” for determining preparation of documentation for explosion protection
• Identifying hazardous areas and utilizing warning signs to alert personnel and equipment suppliers of the potential hazard
• Specifying suitably safe equipment for use in the zone to the engineer or equipment supplier

The end-user is required to evaluate the environment where equipment is to be located and operated. When evaluating hazardous locations, it is important to consider the hazardous material (gases or dusts) itself, how the material may interact with the surroundings (atmosphere D'Angelo Russell Womens Jersey , equipment and personnel), likelihood of explosion due to the surroundings, and the level of any anticipated effects.

Since the introduction of the ATEX Directives in 2003, mechanical equipment manufacturers have been subject to similar certification requirements as electrical equipment manufacturers. Fan manufacturers have been allowed to subscribe to the manufacturing process as detailed in the European Standard EN 14986:2006, “Design of fans working in potentially explosive atmospheres Authentic D'Angelo Russell Jersey ,” which provides a guide for meeting the ATEX Directive (949EC).

European Standard EN 14986 outlines manufacturing and design criteria for fan manufacturers to adhere to. Such design requirements include, but are not limited to, permissib.
