Safety level of a scientific lab

biosafety consulting

Direct exposure to infectious agents in an enclosed laboratory can cause infections, which may be fatal in some cases. Biosafety is a protection measure adopted by scientists to counter the outcome of accidental infections in a laboratory. The adequate safety measures observed not only protect the scientist themselves but also the general public in cases of severe uncontrollable outbreaks.

Biosafety Levels
The severity of an infection outbreak may range from mild or severe depending on the microorganisms under study. Biosafety levels are designed to contain the outbreak of infections. Appropriate action may involve implementation of one or more of the four levels of biosafety protection.

Biosafety Level 3
This safety level is often implemented in laboratories that are reserved for examining rare microbes such as tuberculosis, typhus, bubonic plague, or the Rocky Mountain spotted fever. Nevertheless, such laboratories may also be designated as research centers for viruses like the H5N1 virus, avian flu virus, and the flu virus.

Features of a Biosafety Level 3 Lab
Biosafety Level 3 labs were designed with the risk of the highly infectious and deadly nature of the microbes under study in these labs in mind. These state-of-the-art laboratories are designed to prevent the microbes under study from escaping outside with airtight and hermetically sealed enclosures.

Lab workers dress in special lab suits that include gloves and facial protective gear. Despite adequate training to handle microorganisms, lab workers must work under a scientist or a trained technician whose role may include biosafety consulting. The workstations of workers in a level 3 laboratories are designed to offer them extra protection from accidental exposure.

U.S. Biosafety Level 3 labs
Nearly half of all BSL-3 labs located in the United States are associated with universities. Notable among them include the Center for Disease Control and Prevention, the National Institutes of Health, and the U.S. Army Medical Research Institute of Infectious Diseases.

Biosafety is related to a wide range of fields including ecology, agriculture, medicine, chemistry, exobiology, and synthetic biology. Although the term is mostly associated with the agricultural and medical field, many experts believe that its scope should be expanded to include post-genetic threats, artificial life forms, robotics, and anything that would have direct impact on the natural food chain.

Generally, biosafety involves the application of certain precautionary principles and focus on the biological nature of threatened organisms. The increased need to address the complex issues involved in biosafety have led to the development of a new field known as biosecurity.

Eco-Friendly Ways to Use Technology

Technology is a huge part of everyone’s day to day life. Technology has changed the way a lot of people lead their lives, and for many people, going even a day without technology would be very stressful. Even though technology may seem to make everyone’s lives better, there are some downfalls to being a technology dependent society.

Eco Friendly Ways to Use

Technology can use a lot of valuable energy in the process. This energy is a resource that is not easily renewed. Additionally, some technology use can create excessive waste that is difficult to dispose of. Here are some eco-friendly ways to use technology that can help everyone use less energy and create less waste.

Turn it off and unplug it

The best way to use less energy, of course, is to turn off all of those things that are using energy throughout the day. Many people will leave there electronics plugged in or turned on throughout the day, but if they are not in use, everyone should shut it down and unplug it to save energy. This is a simple task that takes little to no extra time every day.

Use screen savers and dimming settings

There are a lot of people who use their technology on and off throughout the day. For these people, turning off and unplugging may not be a practical option. Screen savers allow people to save energy while still keeping their electronics on throughout the day. Many local Direct TV services will provide screen savers for TVs and other electronics that may not be in full use throughout the day.

Install a solar panel

Solar panels may still seem like a futuristic gadget that no one in this lifetime will have, but solar panels are actually becoming an affordable option for many people to have in their own homes. Everyone can use a solar panel to provide extra energy to their home, solar panels to power specific electronics, or even solar panels to charge the batteries for their cars.

Invest in energy-efficient gadgets

There are a lot more options today for gadgets and devices that are much more energy efficient than their older versions. Everyone can do a lot to reduce their energy use every day by simply replacing things like old cameras, kitchen appliances, and computers.

Switch to LED lights

Not all technology that uses a lot of energy is super advanced or complicated. Light bulbs in the home use a lot more energy than many other technology items that people use every day. Changing out old light bulbs for new LED light bulbs that use less energy and last longer will help the entire home use less energy on a daily basis.

Use a smart power strip

Not all technology items need to be changed to reduce overall energy use. There is one option that can help every electronic device use less energy. Smart power strips provide a buffer between that controls every electronic device use less energy and save power.

How Swedish Cities Stay Warm With Renewable Energy

A number of Swedish municipalities are arguably leading the world in environmentally-friendly heating. Heat and power production in such cities is combined with district heating systems to provide affordable, ecologically-sound heat for citizens.

District heating systems tend to use heat from renewable energy sources, which is then piped through the city for homes and other buildings to tap into rather than using their own separate boilers. Biofuels such as wood and peat are commonly used as well as combustible household waste. Other sources of heat may also be used, such as geothermal heat from deep underground or heat reclaimed from industrial processes. These types of heating system have played a major role in the relatively high level of independence from fossil fuels that Nordic countries have managed to achieve.

Altogether, around 60% of Sweden’s heating comes from district heating systems. Overall, about 85% of all public buildings and multiple-dwelling homes connected to these networks and such networks exist in all of Sweden’s towns. The birth of the Swedish district heating networks really took place in the 1950s, when many Swedish municipalities were looking into ways to reduce air pollution. They were also keen to find more efficient ways to produce electricity, and found that combined production of electricity and heat represented a significant improvement in efficiency. Helped by a culture that is generally supportive of community infrastructure, district heating took off in the following decades.

Many people around the world are starting to wonder whether the international community could do well to learn from Sweden’s example. While other countries struggle with energy usage, pollution, and declining stocks of finite natural resources, Sweden has almost removed fossil fuels from its heating sector. District heating systems are also relatively easy to operate. The infrastructure can be costly and challenging to construct, but it doesn’t come with the same challenges of internationalism that might hinder other types of infrastructure such as electricity.

Even those countries that do already use district heating systems may have things to learn from Sweden. In Eastern Europe, this kind of heating solution is more common than on the Western side of the continent. However, it is still largely based on coal, so while it offers advantages over self-contained boilers for each separate building it still produces large amounts of carbon and draws on finite resources. In Sweden, by contrast, the use of fossil fuels is virtually non-existent in district heating, yet the system continues to serve countless citizens well.

Swedish district heating solutions have made use of renewable energy sources such as wind and solar power, but sourcing enough renewable heat through these methods alone would be challenging and perhaps impractical. As a result, a big emphasis has been placed on biofuels as a replacement for traditional fossil-fuels over the past two or three decades. The way district heating has been combined with electricity production is also something that many other district heating systems around the world lack, yet offers a significant boost in overall efficiency.

Old Crafts as New Careers

Old_Crafts_as_New_Careers

I recently met a wise 70 year old man from my hometowm who raises Oxen. He also builds log cabins… using no modern technology. To say that I was impressed is an understatement.

On a cold day recently we sat next to a fire in one of the log cabins on his property. The fireplace was made of stone. Each stone had been collected from the creek bed down the side of the mountain. He even told me about the large, sweeping headstone that ran across the top front of the fireplace. He said he spent months looking for the perfect stone and had almost given up hope when he was hiking the creek and it just popped out of him. If you saw this stone, you’d say it was a miracle. It is one continuous piece of long rock, with one flat side and one curved side that seems like it was made to fit this function.

The reason I tell this story is to make a point. Human beings receive a great deal of joy from working with their hands. From making things. From producing things. But many of the jobs in today’s economy leave people feeling dispirited and hopeless. They do not foster creativity or joy.

As I look to raise and shape my boys, I hope to encourage them to pursue a job not primarily for the money, but for the joy of learning a craft and making something wonderful. I want my boys to be able to look at their handiwork and feel a sense of pride.

Whether it’s being a farmer or being a gunsmith or a log cabin builder, the key is to find the right balance between effort and reward while minimizing stress. I believe that working the land or building something physical offers the greatest intangible rewards – but you do have to pay the bills too.
