Lab lets public use 3-D printing and laser tools

Laser engraving and cutting may release toxic
fumes that can affect people's health, studies show.

On any given day, an unusual cross-section of artists and entrepreneurs might be found tooling away on the cutting and industrial printing machines at a Central Square lab in Cambridge: a maker of percussion instruments, a fashion designer, even the owner of an electronic cigarette retailer.

The lab is called Danger!Awesome, and it is helping to introduce 3-D printing and laser-cutting technologies to people who don’t have the knowledge or access to factory- grade equipment to turn their big ideas into products.

The lab also performs professional-grade jobs for corporate clients, including the nearby Google Inc. offices. But to get 3-D printing to become an everyday technology adopted by the masses, cofounder Ali Mohammad said Danger!Awesome’s main calling is to teach hobbyists and entrepreneurs the technology isn’t all that difficult to master.

“Even if you don’t think you can make something, we will hold your hand through the entire process,” Mohammad said.

Like other labs, Danger!Awesome has both 3-D printers and laser cutters.

The former create solid objects by slowing extruding layers of plastic or other materials, based on a pattern designed in a computer program.

The latter starts with a block of material and meticulously burns away everything except the desired shape.

“You get this satisfaction from creating things,” Mohammad said. “There is something deeply, primally satisfying about building something you can touch.”

The company is among a number of startups in the Boston area anticipating that people will pay for training and access to bleeding-edge fabrication technologies.

In Somerville, Astisan’s Asylum trains members to use a Stratasys uPrint. The Printing Bay in Waltham offers classes and access to a MakerGear M2.

And on Newbury Street in the Back Bay, the 3-D printer manufacturer MakerBot has opened a store where the public can watch demonstrations of 3-D printing, scan and print their own designs, and buy a machine for their own use.

In Burlington, Einstein’s Workshop offers science and engineering classes aimed at children — including courses in 3-D printing and laser cutting for kids as young as second-graders.

“When you give kids access to these machines, it’s amazing what projects they think of themselves,” said workshop founder Henry Houh, who took a laser-cutting class at Danger!Awesome.

Visual artist Lannie Hathaway got so hooked on the new technology that she now works at Danger!Awesome, where she continues to use the machines for her own engraving and illustration projects.

“Using the tools that are used for engineering to make my own work come to life was very exciting,” Hathaway said.

The 3-D groundswell is being embraced by academia, as well.

Northeastern University, for instance, opened a comprehensive 3-D printing, 3-D scanning, and laser-cutting lab as part of its library system last year, and is developing coursework around it.

And the Massachusetts Institute of Technology supports a global network of 3-D printing laboratories through the Fab Foundation,a nonprofit started by the school’s Center for Bits and Atoms.

Mohammad was a doctoral student at MIT in computational linguistics when he stumbled on the technology, sneaking into the labs with laser cutters late at night to try out the equipment.

He became friends with Nadeem Mazen, and they decided to start a business. Their lab does about 50 orders a week, more around the holidays.

A changing climate blamed for bigger wildfires

Changing climate leads to bigger, smokier wildfires

Bigger wildfires may become a bigger
threat to public health, experts warn.

This year more than 4,000 wildfires burned almost a million acres across the Northwest. That falls below the 10-year average, as only one year in the last decade has had fewer fires than this year.

Scientists are quick to point out that no single fire season can be attributed to changes in the global climate, but as summers in the western half of the United States become drier and warmer, the chances of bigger, longer smokier fire seasons is expected to increase.

A recent Harvard University study has found that by 2050 the wildfire season for the western United States will be about three weeks longer and be up to twice as smoky because of changes connected to global warming. 

In the Pacific Northwest, the area burned during the month of August could increase by 65 percent.

Wildfires come with smoke and health effects

With larger, longer-lasting wildfires, air quality is projected to suffer. Based on the amount of on-the-ground biomass available to be burned, researchers expect to see wildfire smoke increase in the Northwest between 40-100 percent in the coming decades.

Wildfire smoke is made up of tiny organic and black carbon particles that are a fraction of the diameter of a human hair. These microscopic particles can travel deep into the lungs and even cross over into the bloodstream. 

Inhaling those fine particles isn’t good for anyone, not even healthy people. Smoke can irritate the eyes and airways, leading to coughing, headaches, scratchy throats and runny noses. 

And for some people, wildfire smoke can be life threatening. It can trigger asthma attacks, heart attacks and even strokes.

Wildfire smoke is already one of the biggest drivers of degrading air quality throughout the Northwest. Over the past few months, wildfires have created hazardous and smoky conditions, and clouds of smoke as big as thunderheads billowed over communities in Southern Oregon and Central Idaho.

Looking back on U.S. fires

Since the 1980s, the overall number of wildfires and the amount of acres burned in the United States has increased steadily. As the climate has warmed, snow melts earlier and dry periods have lengthened both of which favor fire conditions.

Other factors contribute to increasing the size and severity of wildfires, including a history of fire suppression over the last century. Fire suppression can lead to an abundance of biomass on the ground in forested areas. That biomass serves as kindling that turns what might have been a small manageable fire into an unstoppable megafire.

But even after you account for fire suppression, climate change is still a factor. Places like Yellowstone National Park, which have experienced larger wildfires in recent decades, never had active fire suppression.

Extreme fire behavior has become more common.

Breathe better air indoors

During wildfire season and beyond, a movable indoor air purifier with an activated carbon and HEPA air filter system can help remove potentially dangerous airborne contaminants.

Smoke particles and chemicals as well as other volatile organic compounds, allergens and mold spores can effectively be trapped with activated carbon and HEPA. Activated charcoal adsorbs chemicals, gases, odors and fumes, while HEPA traps 99.97% of particles at 0.3 microns.

Electrocorp offers large and small-footprint air cleaners for commercial, industrial and residential use. For more information, contact Electrocorp today.

Facility management: Humidity reduces airborne flu

Better facility management can reduce
sickness and absenteeism rates.

A recent study carried out by the US National Institute for Occupational Safety & Health (NIOSH) has shown that the airborne transmission of the influenza virus is significantly reduced by maintaining an atmosphere of 40% relative humidity (RH) and above.

To test the effects of humidity on airborne influenza, aerosols of flu virus were “coughed” into a room’s atmosphere by a mechanical manikin at humidity ranging from 7-73%RH, while the air intake from a breathing manikin in the room was monitored.

The air inhaled by the breathing manikin showed that at ≤23%RH the airborne flu virus retained 71-77% infectivity, while at ≥43%RH infectivity dropped to just 15-22%. The study showed that inactivation of the virus at the higher humidity occurred rapidly after coughing with most of the decline occurring in the first 15 minutes.

The study concluded that maintaining relative indoor humidity at 40%RH and above will significantly reduce the infectivity of an aerosolized influenza virus.

It is estimated that over 7.6million working days are lost in the UK each year as a result of flu-related sickness, costing the UK economy over £1.35 billion per annum. Most experts think that flu is spread by tiny droplets created when people with flu cough or sneeze, which can remain in the air for hours.

“This study shows how important it is to maintain an optimum humidity in the workplace to reduce absenteeism and especially in areas of high risk to airborne viruses, such as hospitals and doctors’ surgeries,” said Tim Scott, a humidification specialist.

“Although many professional bodies, including BSRIA, CIBSE and HSE, all recommend maintaining indoor humidity at above 40%RH it is not uncommon to see humidification systems being turned off to reduce operating costs. A low humidity is not as noticeable by employees as a low temperature, so it can go unnoticed. However, the true cost of not maintaining indoor humidity can be poor staff health and an increase in absenteeism, which can far outweigh the cost of operating the building’s humidification system.” Scott said.

Provide cleaner and healthier air at the workplace

Apart from the flu virus, there are many other airborne contaminants that can affect employees' health, well-being and productivity.

Air cleaners for offices and other
work spaces provide cleaner and
healthier air.

Many workplaces expose employers and employees to airborne chemicals, particles, dust, allergens, mold, viruses, bacteria, odors and gases. 

Most of these contaminants can be controlled with adequate ventilation, best facility management practices and air cleaning.

Electrocorp offers versatile and efficient air cleaners for industrial and commercial use, which provide cleaner and healthier air at the workplace.

The air purifiers strip the air of chemicals, particles and biological contaminants by forcing the air through a deep-bed activated carbon air filter, a HEPA filter and various pre-filters as well as an optional UV germicidal filter.

The air cleaners come in many different sizes and with a variety of options. They are custom-built to provide the protection that is needed.

Mold health effects spur complaints by ex-sheriff's worker

Regular exposure to mold and mold spores has been linked to
adverse health effects such as respiratory disease and headaches.

Working in a sheriff's office should be safe, but one former worker has filed a complaint, saying she was unjustly fired after experiencing health effects from mold poisoning.

The former clerk in the Lee County Sheriff's Office was fired for using more sick days than she had accrued.

The former clerk, who had worked in the office for seven years, said she suffered from COPD, (a chronic lung disease), anxiety, panic attacks, headaches and back pain after being exposed to mold. She filed a complaint with the U.S. Equal Employment Opportunity Commission (EEOC) accusing the sheriff’s office of disability discrimination and retaliation, saying they fired her instead of dealing with the problem.

She plans to sue the sheriff's office over her medical problems.

The office has since been closed for mold remediation, after the air was tested by trained staff, and renovations are supposed to begin.

Mold - a serious exposure risk

Regular exposure to mold spores has been linked to respiratory disorders such as asthma and COPD as well as neurological symptoms such as anxiety, depression, aggression, short-term memory issues and blurred vision.

Those affected have reported headaches, rapid heart beat, chronic fatigue, pain and other health effects.

Seek medial treatment if you experience any of these symptoms. Mold health effects are often misdiagnosed.

Construction dust a big health and safety risk

Inhaling dust and particles at construction sites is a
major health and safety issue, officials say.

Construction workers that don't protect themselves from inhaling even small amounts of dust on the job could put their health at risk, health and safety officials say.

In Britain, about 500 workers die each year from conditions related to the inhalation of dusts from concrete, wood, sandstone, mortar and gypsum.

In order to reduce these numbers and improve the health and safety for construction workers, Britain's Health and Safety Executive (HSE) offers a free seminar on Sept. 20 on the dangers of construction dust and measures of protection.

The seminar is organized by the Working Well Together group and will take place in Coalville, Leicestershire, to increase awareness among managers and supervisors about health effects associated with dusts.

Dust inhalation linked to ill health

One major health effect is the possible development of silicosis, a respiratory disease caused by breathing in silica dust.

Silica is a common, naturally-occurring crystal and it is present in many construction materials.

Intense exposure can lead to health problems right away, but typically, health effects only emerge after 10 to 15 years of regular exposure.

"Construction dust is not just a nuisance, it is a serious risk to workers' health," said Chris Lucas of HSE’s Health Risk Management Unit in a news article about the seminar. He'll be speaking during the seminar. 

"Regularly breathing in even small amounts of dust over a long time can cause life-changing and life-threatening lung diseases, including cancer," he added. "Common jobs like cutting or grinding concrete, chasing out mortar, drilling in enclosed spaces or sanding wood can be high risk if not properly controlled."

Poor air quality = Poor productivity

Welding without proper ventilation
is a health-risk

A British lighting company has been prosecuted for subjecting its employees to poor working conditions. 

Despite specialists giving recommendations on how to improve standards, and a Health and Safety Executive (HSE) inspector uncovering multiple areas where the company was not meeting health guidelines, it continued to function under the same circumstances for at least eight more months. 

The company was recently fined for sub-standard bathroom facilities, defects in the electrical system, little to no heating in the building, and no ventilation in the welding and powder-spraying sections.

These failings highlighted the extreme risks workers took when going to work every day. One inspector even stated he had never seen such poor conditions in the ten years he’d been an inspector. 

This company is representative of poor indoor air quality sometimes found in the industrial sector. Many health hazards surrounded the workers, such as bacteria from the bathrooms, the risk of being electrocuted by the faulty systems, catching various colds or flus due to a lack of proper insulation and heating, and breathing in toxic fumes in both the spray booths and the welding area.

In 2010/2011, statistics revealed that work-related illnesses affected approximately 100,000 people in Yorkshire and Humber, England.

Indoor Air Quality in the Industrial Sector

Working in the industrial sector can be very stressful. Many people are faced with tasks that involve welding, sawing, electrical work, and/or the handling of toxic chemicals. Working with such materials requires a safe and healthy environment. 

It is the companies' responsibility to provide clean and toxic-free working conditions so employees will work more efficiently, and absenteeism, due to work-related illnesses, will be minimized. 

A healthy working environment makes for a happier and healthier employee.

Improving a company’s indoor air quality

Electrocorp's Fume Extractor

If you’re a company that is predominantly in production or manufacturing, and many duties involve welding, soldering, sawing, etc…, the best way to mitigate poor air quality is to use Electrocorp’s Fume Extractor series of air cleaners. With metalwork, it is recommended that each person have a Fume Extractor by his or her side. 

The units have a spark arrestor as well as a maneuverable arm and intake hood which can be moved close to the fumes and sparks. The hood allows the toxic chemicals to be absorbed from the source and immediately taken out of the ambient air, thus providing a healthier indoor air quality for all employees. 

The units use 40-80 lb activated carbon filters to adsorb the toxic chemicals, and HEPA filters help extract particles from the air.

Report pegs industrial air cleaner market at $6.3 billion US for 2012

Activated carbon is a preferred adsorbent for
gaseous contaminants in many industrial applications.

The Scrubber/Adsorber/Biofilter World Markets report by McIlvaine paints a positive outlook for the industry for next year – forecasting demand from the pulp and paper, chemicals, metals, mining, waste incineration, refining and waste-water industries.

The biggest market will be East Asia by far, the report says, with North America in the second position.

The Canadian and American pulp and paper industry may be looking at scrubbers for recovery furnaces, lime kilns and toxin remobal elsewhere in the processes.

China and Indonesia are expected to be big purchasers, especially for the steel industry (to capture dust and other emissions) and the cement industry, while Indonesia and other East Asia countries have a growing pulp and paper industry in need of odor and chemical control.
