Asbestos Insulation Bag Test Article (page 1)
Interesting article from a 1970 publication with information about a 1969 trial test comparison performed on newly designed plastic bags containing asbestos insulating material. The "new" bag design featured a water inlet whereby water was added directly into the bagged asbestos insulation while simultaneously hand kneading the mixture still inside bag. Air quality sampling data collected during the 1969 plastic bag test trial indicates that airborne fiber concentrations exhibited levels between a mere 4.4 fibers per cubic-centimeter of air (f/cc) and 7.5 f/cc, using two different types of asbestos insulation materials each containing either 15% or 50% asbestos content. These results were apparently a significant reduction to airborne asbestos fiber dust when compared to a standard open tub-mixing technique (up to 46 f/cc). Admittedly, this lower result was an improvement and at least a start in the right direction. However, for consideration, compare the 1970 "improved" result of 7.5 f/cc with OSHA's current "permissible exposure limit" (PEL) to airborne asbestos fibers, at 0.1 f/cc. The 1970's trial shows the "reduced" concentration level at 75-times or 7,500% greater than today's OSHA PEL. For further thought, consider a person with an average at-rest respiratory rate of 7.5 L/min. while breathing air with the "permissible" airborne asbestos fiber concentration of 0.1 f/cc for 8-hours. This amount equals 3,600 liters of air in an 8-hour timespan. One liter equals 1,000 cubic-centimeters (1L = 1,000-cc); thus 3,600L = 3,600,000cc. At OSHA's PEL of 0.1 f/cc, breathing 3,600,000cc of air in 8-hours would theoretically result with inhalation exposure to 360,000 fibers (at-rest). Respiratory rates increase with added physical activity, especially while working on a strenuous construction job, where workers could experience breathing 20-30+ liters of air per minute; a factor of three to four-times. Working at 30-L/min. breathing rate for 8-hours, 4 x 360,000 = 1,440,000 fibers (at the "permissible" 0.1 f/cc concentration). Even further, these latter scenario results would typically be based upon concentrations determined by the less-than-reliable phase-contrast microscopy (PCM) analytical method, using standard equipment with inherent optical resolution limitations and incorporating a fiber-counting technique that excludes all "fibers" less than 5-microns long by default. Actual respiratory exposure to airborne asbestos fiber levels could possibly be much greater than reported PCM concentrations.Dalla Corte Newsletter Test WCE ENG
Constancy and high thermal efficiency have always been two strong points of Dalla Corte espresso machines. Three years after passing the thermal stability test in Vancouver (Canada) with the Evolution coffee machine, the new dc pro 3 groups model also passed the quality test at the World Coffee Event, the society who, starting from this year, develops and promotes all the barista championships of the Scaa and Scae community worldwide. The Maastricht test (Holland), held over two days, included the exit water temperature measurement and stability evaluation. The machines were also examined from an ergonomic and functional point of view. Passing these tests represents an important recognition of the effective quality of the Dalla Corte machines since the endorsement comes from a third party with very high quality standards, the World Coffee Event. Thanks to this, they are eligible to compete for the equipment sponsorship at the World Barista Championship, the World Latte Art and the Coffee in Good Spirits. “Ever since 2001, when we launched the Evolution project, our first machine, our target has been the “proof of taste”: a challenge that spurred us to go beyond the traditional standards – says Paolo Dalla Corte, founder of the Company, satisfied with the achievement. – We were the first to develop a machine with independent groups: our forecast was that within 10 years at least 60% of the producers would have followed our example. The confirmation came in Maastricht, our forecast was even exceeded. In fact, six more companies underwent the machine thermal stability test conducted by the World Coffee Event, with independent groups machines: La Cimbali, Astoria, Rancilio, Unic, La Nuova Simonelli and Victoria Arduino. Luckily the long experience matured in many years of research and development and the improvement of our technologies allow us to remain the leaders in this field in terms of quality, thermal constancy, energy saving and functionality. Today, just like yesterday, we firmly believe in continuous research, in the promotion and diffusion of the espresso culture, therefore in a free-standing quality: a heritage of know how and experience that allows us to trustingly answer to the competition announcement for the sponsorship of the barista championships of the next triennium”.
Water is our most vital resource. Yet few understand even the basics of watershed ecologyRelated topics:
Watersheds: A Practical Handbook for Healthy Water provides a fascinating overview of the fundamentals of ecology from the simple concept of a watershed to the biological intricacies of a wetland ecosystem and its implications on the environment.
More than 100 illustrations, especially done for this book, help explain the numerous environmental issues and the intricate web of life that connect each of us to all other life on the planet through out involvement in the watershed cycle.
Watersheds includes information on:
water and nutrient cycles
bioregions and aquatic habitats
exotic species invasions
- water and air pollution
Special "How Can I Help?" sections throughout the book provide practical and meaningful ways in which individuals can make a difference to the health of watersheds by reducing water and air pollution, preserving native forests, and helping restore the health of streams and rivers.
