Reasons for Investing in an Industrial Ventilation System



Manufacturing facilities are expected to meet health and safety norms laid down by organizations like ISO. To ensure that all the necessary measures are met, many companies go for industrial ventilation systems. These help in capturing dust, smoke, vapor and other contaminants that may be harmful to employees. Industrial facilities have to take into account factors like internal and external environment, air regulation, air quality, and overall health benefits. Industrial ventilation systems provide a one stop solution to both problems.
Why invest in industrial ventilation systems?
The following are the advantages for investing in an industrial ventilation system:
  • Protection from Contaminants: Manufacturing facilities are prone to a variety of hazardous substances. These include gases, aerosols, small inhalable particles, smoke, fumes, and vapors. Continuous exposure can lead a person to suffer from illnesses such as headaches, eye irritation, chest pains, siderosis, cancer, and pulmonary edema. Its exhaust components are designed with a vacuum that easily captures the above mentioned substances with ease.
  • Economic efficiency: While one would think installing system incurs more expenses, the reality is quite the opposite. Many companies have found that investing in industrial air cleaning systems can actually bring down costs. The reason for this is, the expenses required to install and maintain the system is quite equitable. Manufacturers design their system to be self sufficient to minimize need for maintenance or human intervention.
  • Control and Regulation of Air: This is perhaps the biggest advantage of installing a system in your facility. An industrial air cleaning system gives you complete control over the airflow in the facility. It gives you the freedom to create a comfortable work environment for employees. The system can also help to change the temperature inside the facility depending on the external temperature. The employees will no longer have to bear with the extreme spikes of internal temperatures.
  • Air Quality: It improves the indoor air quality by getting rid of pollutants. It can filter and condition the air flow and prevent problems like moisture and mold issues.
  • Protection from Accidents: A variety of production operations generate combustible dusts. When these dusts interact with gaseous elements in the factory's internal atmosphere, it can lead to explosions and fires. To prevent such accidents, manufacturers design their industrial ventilation systems with dust collectors. The exhaust components are also constructed to prevent any dust particles from leaking back into the facility.
It is evident that one can reap several benefits from installation of industrial air cleaning system in a manufacturing facility.

4 Effective Ways of Preventing Explosions - Fire Safety Structural Protection


Explosions are a common cause of fires and a lot time and resources has been spent in coming up with the best ways of preventing an explosion ever happening. The following 4 techniques of 'Structural Prevention' involve constructing buildings in such a way that is specifically designed to prevent fires. The techniques have been proven to effectively limit the risk of explosions and fires, helping save lives in an often subtle way.

The first technique to be described is 'compartmentation'. Dividing a building into compartments or fire-tight cells using fire resistant materials can prevent the spread of fire and smoke within a building as well as the passage of vapour or dust clouds.

Fire compartment walls, floors and doors generally must provide a 60-minute resistance to fire, but this may vary depending upon the level of risk within the compartment. Walls, floors and doors subdividing such compartments generally must provide a 30-minute resistance.

Ceiling and floor voids as well as openings around pipe work and other services can allow air to feed a fire, as well as assisting in the spread of fire and smoke. Fire Stopping can be described as preventing the spread of smoke and flame by placing obstructions across air passageways.

The second effective technique is isolation. Isolation stops the explosion reaching other areas of the plant through pipes and ducts. It prevents the pressure from a primary explosion starting a secondary explosion and prevents the possibility of jets of flame issuing from long pipes. Depending upon the maximum explosion pressure, vessels may be constructed to contain the explosion. Most vessels that may be at risk of dust explosions are designed so that they will absorb the force of an explosion and not rupture.

The third technique is effective plant layout. Buildings that could be in danger of dust explosions must be designed along the same lines as any plant which has an explosion risk. The following features should be considered:

• Wherever possible, they should be isolated from other buildings
• Buildings should be preferably one storey high
• If inside, the vulnerable area of the building should be reinforced
• The rest of the areas of the plant must protected by a blast wall
• Sufficient venting to avoid structural damage from over pressure must be provided

The fourth technique is suppression. There are 3 ways to avoid creating an explosive dust cloud without modifying the dust itself:

• By adding inert gas to the atmosphere. This will reduce the amount of oxygen in the process area and thus reduce the chances of explosion
• By ensuring the dust is outside of its explosive (flammable) limits
• By adding inert dust, however this is not suitable for many industries as it contaminates the product.

The above 4 techniques are some of the main fundamental ways of preventing loss from fires right at the first stage of building an environment to live in or to work in. Designing a structure in such a way that helps prevent fires and helps limits the potential of loss during a fire is the best way of ensuring survival in the case of a fire emergency. Further information should also be sought to learn about the additional ways of preventing loss due to fire, to ensure that all eventualities are considered.

Safeguarding Against Dust Explosions


What is a dust explosion?

Dust explosions are a result of the rapid burning of flammable mixtures, such as those found in dust clouds in a workshop environment when mixed with the surrounding air. When this mixture is combined with an ignition source, e.g. a flame, and the dust particles have gathered into a big enough group to keep the flame sustained, the dust cloud becomes combustible. Research has shown that 70% of all powders are flammable, owing to their particle size and density which allows them to sustain the flame long enough for combustion.

If the dust particles are freely moving and are heated sufficiently, this will cause a flash fire which will momentarily combust. However, if the dust particles are concentrated within a small area, such as a vent or inlet for machinery, this will cause an explosion and can result in complete destruction of the machinery and even the building.

Because it takes time for enough dust to build up and result in an explosion, proper precautions and vigilance can reduce the likelihood of an explosion from happening.

What is special about dust explosions?

The biggest cause of dust explosions is from friction and mechanical failure. Unlike gas or solvents, dust particles pose a bigger risk to workshop machinery and workers' safety. Whereas gas and solvent particles can dissipate into the air and fall below flammable levels, dust particles are heavier than air and therefore fall onto surfaces until a strong enough air current raises them back into the air where they can regroup with other dust particles. If a big enough collection of particles is made and the conditions for combustion are met, this can result in an explosion. This is why finer particles are more of a danger, because larger particles are less likely to enter the free flowing air again, whereas smaller particles are much lighter, and therefore easier for the air to carry.

This poses a very real risk for machinery such as sanders, saws, and lathes where wood waste is produced.

Invest in a Dust Extraction System

As you can see, there is plenty of reason to invest in a dust extraction system. Not only are the potential dangers to machinery and your working environment a real problem, but with all of that dust floating about in the air, improper ventilation could also affect the health of your workers and put them at undue risk.

Is Automation Of Industry Good For Us?


The companies matters most in making more money and they are always on the lookout for ways to minimize the costs to make the profits for the products they make. This is where factory automation comes into play. A factory that relies heavily on automation minimizes their expenditure as they have not to pay the labor costs, to produce products thereby increasing profits all the way around.

For every new innovation implemented there is always a debate on the pros and cons of it. So let's discuss over here the advantages and disadvantages of the industry innovation over here.

Automation relies on programmed machines to perform tasks which were performed by a human before. One of the problems is that these machines cost in the millions of dollars, which means a very high initial investment for the company before it starts. Now the investment which is made is meant to be recovered. Now the investor's thinks to recover it fast in the mode of profits but it's necessary to get the investments back either if it's in fast or slow mode. Now it's depend on the way the production is done or starts and how the work gets completed in the right time to get it delivered to the market to earn good profits to recover the investment. So it is very important to choose the way of production to turn the organization into profits. In theory, the investors can make the investment back in a few years by not having to pay an employee to do the job, who was replaced by the machine. But what if the job becomes unnecessary? This means that they spent a lot of money that was not needed. This money can be invested in the other part of business to develop the organization, like hiring skill workers in other departments where machines can't replace human.

The other debate can be as these machines are machines which can replace man but never can replace the brain of man. It is the human who can react to any debacle happen at any time of production, but whereas the machines don't have the much knowledge to react at any debacle till the program for the machine is not structured to do so. Most of us think that the machines are perfect to replace human but it is not the case. The machines have to be updated every time a debacle occurs so that the machine is ready for the next time so that the loss does not occur next time. Whereas the human is always ready for anything and to sort out the problem anytime required.

The other biggest factors affected by the automation of the industry are the humans, because of loss of work. It takes jobs away from the people who need them badly. It does harm the economy because the more people that are out of jobs the worse the economy is. This can change the face of the region.
So there are many advantages and disadvantages of automation, but this has to be utilized limitedly for the benefit of human kind but not to worse hit the human life. Utilize it for the best cause to serve human in the best way.

How Has Computer Aided Drafting (CAD) Revolutionized Engineering Industry?


CAD, Computer Aided Design has brought about a technical revolution in the Engineering Industry. CAD Services can be classified into broad categories like Architectural Services, Structural Services, MEP and Mechanical Services. CAD for Engineers and Architects today is like Oxygen for the living. CAD Services is a boon for all companies' worldwide who would like to execute CAD projects with minimum cost and quick deliverable capacity. With the consistently growing demands in construction industry and CAD services have achieved eminence across the globe. This technology has contributed immensely in development of Construction Industry, Building and Infrastructure development, Green Building concept along with other Engineering Domains like Machine Designing, Aeronautical sheets, Transformer designing, GIS, Pressure vessel designing etc..

Engineering industry today uses CAD Services to ensure Less cost, best quality, quick turnaround time along with excellent project efficiency. CAD is no longer limited to AutoCAD. There has been a great evolution in the CAD Software too. CAD professionals globally use software which is helpful in are using latest software like AutoCAD, Revit, 3D Studio Max, Pro-E, Solid Works, Inventor, MicroStation etc to execute Designing, Drafting and Modeling projects. With the help of such software, the entire project execution cycle has come to a new arena due to CAD Services. It is now possible to visualize an entire building and it's detail even before it is completed. This is possible with the help of "Virtual Construction Modeling" also referred to as Building Information Modeling in Engineering Industry. 3D Rendering makes it possible to give any building or product a photorealistic feel before the actual construction or manufacturing of a product. This development has also caused increase in companies providing Engineering and CAD Services. With transformation of blue prints created manually to digitization of CAD Drawings, many opportunities have opened up for Architects, Engineers and Drafters.

CAD services assure absolute digitization of manual drawings to computerized drawings via scanned pdfs, hand-drawn sketches or old manual drawings. Companies are using different approaches and techniques to take utmost advantage in terms of project execution. As mentioned earlier, CAD Services are no longer limited to one particular domain or segment. Arrays of services are covered under one umbrella. Besides project execution, computerized CAD Drawings or Images are easier to maintain, save or send across to clients. There is no risk of images or drawings being damaged in course of time. Errors can be rectified easily without taking much of time and can aid to quick turnaround. In software such as Revit, a change made in one part of the model reflects in the entire model by reducing manual intervention. This also facilitates definition and extraction of individual sheets or different part of drawings and every minute detail.

These are one of the main reasons that across the globe, major construction houses or Infrastructure companies are eminently outsourcing CAD Services. This process over a period helps companies gain advantage over their competitors who do not outsource their requirements. CAD Technology has evolved into a different era in a short span of time and is constantly evolving into giving better shape to the Engineering industry. CAD Services now helps CAD companies and professionals manage their Designing Drafting or Modeling projects more efficiently. Companies offering CAD Services and companies who are constantly upgrading their technical skills will always be in an advantageous position compared to companies who still rely on traditional methods of executing projects.
