"The American cement industry cares deeply about work- place safety and these projects prove that," said PCA Pres- ident and CEO Michael Ireland. "We are proud of these efforts to pursue excellence in safety innovation for their company and their colleagues." dŚĞĨŽůůŽǁŝŶŐĂƌĞƚŚĞϮϬϭ^ĂĨĞƚLJ/ŶŶŽǀĂƚŝŽŶǁĂƌĚǁŝŶŶĞƌƐ Quarry and Mine Ash Grove Cement Co. – Louisville, Neb. The plant's D10 Dozer Power Step system eliminates the need for employees to ascend and descend the dozer in the traditional way, making access safer and more efficient. The Power Step attaches to the dozer frame and works hydrauli- cally. At ground level, the operator steps into a small, railed platform and affixes a chain across the entry. Using hand controls,they activate the hydraulics which smoothly raises the Power Step to the operator deck. When exiting, the pro- cess is reversed except that the latch mechanism is released. The Power Step has a fail-safe feature that slowly lowers the platform to the ground if hydraulic pressure is lost. Facilities Ash Grove Cement Co. – Durkee, Ore. The facility's beltlines have an emergency stop cord running alongside that if pulled will cause the beltline and other in-line devices to shut down. Emergency cords are inspected weekly but due to variation between inspectors, the pull cord could be loosened or tightened simply due to its appearance. To solve this problem, a tension gauge reference device with three color-coded level markers (Red–Tight; Green–Good; and Yellow–Loose) was fabricated and installed. This device gives a visual reference for inspectors to quickly determine the exact tension of the emergency stop cord so they can make immediate adjustments, if needed. Ash Grove Cement Co. – Foreman, Ark. Ash Grove Cement developed an oil skid that enables the oiler to safely transport large quantities of oil closer to the equipment for which it is intended, reducing the potential for back and crush injuries. The skid is securely attached to a forklift by safety chains and, with an onboard electric pump, oil can be pumped to any equipment that's within 50 ft. of the skid. The skid can also be used to remove oil by putting the suction hose into the oil reservoir of the equipment or attaching it to the drain plug. Distribution Votorantim Cimentos, St. Marys Cement – Detroit The plant was challenged with high back-pressure on its pneumatic conveying pipelines causing an excessively noisy environment with dosimeter readings reaching 107dBs. A team developed a plan to increase the air nozzle size by ĂŶĂǀĞƌĂŐĞŽĨϲϬйŝŶƚŚƌĞĞŵŝůůƐƚŚĂƚƌĞƐƵůƚĞĚŝŶĚŽƐŝŵĞ- ƚĞƌƌĞĂĚŝŶŐƐĚƌŽƉƉŝŶŐďLJϰϮй•dŚĞƐĞŵŽĚŝĨŝĐĂƚŝŽŶƐĂůƐŽ increased the life span of the rotary compressor blades. The changes made a quieter work environment by improving working conditions, lowering risk, and reducing the require- ment for dual hearing protection. Pyro-Processing Buzzi Unicem USA – Festus, Mo. Buzzi Unicem USA designed a simple single-action tray sam- pler that could be pushed under falling clinker hydraulical- ly. Once the device collects clinker, and while being pulled back, it allows the sample to fall into the chute by means of PCA Announces 2019 Safety Innovation Award Winners New Report Touts the Value of Resilient Design and Construction The Portland Cement Association (PCA), released a new report focused on resiliency titled The Real Value of Resilient Construction. The report demonstrates through historical data, evidence from external sources, and comparisons of building materials that resilient design and construction built with concrete leads to longer last- ing buildings due to concrete's ability to stand up to nor- mal wear and tear and resistance to extreme weather events. "U.S. taxpayers cannot afford to continue building and rebuilding the way we did in the past," said Michael Ireland, PCA President and CEO. "Strong, robust structures ensure community continuity and provide long lasting value for scarce taxpayer dollars." On a national scale, between 1996 and 2014, damages in the United States due to hazards (hurricanes, tornadoes, floods, earthquakes, wildfires, etc.) totaled over $377 Bil- lion according to the National Weather Service. The Real Value of Resilient Construction notes that reinforced con- crete structures reduce recovery costs after disasters hit and the upfront costs of incorporating resilient concrete features may not be significant, and are likely to save mon- ey in the long run. The report also looks at how concrete buildings are the new "green" buildings. Structures that last longer reduce envi- ronmental footprint because their emissions, attributed to heating, cooling and operation, can be spread over many decades. Incorporating concrete can also contribute toward achieving points in the United States Green Building Coun- cil LEED program, which is the leading program for green building and communities worldwide.
