This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Current manure pit-safety ventilation research has been limited to determining the minimum amount of time required to evacuate hazardous gases to allow human entry into confined-space manure storages. Commonly installed negative pressure pit ventilation systems reduce the level of contaminant gases in the manure pit air space, but the negative pressure pit fans are usually too small to effectively ventilate a manure pit for safety purposes prior to and during human entry. The preferred method for ventilating a manure pit for human entry is to use a positive pressure pit-safety fan that delivers fresh outside air into the manure pit air space at higher air exchange rates. However, there may be cases where ventilating for a longer duration at lower air exchange rates may be desirable, such as when a pit has a slotted cover and there is an occupied animal living space located above. In these cases, too high an air exchange rate in the pit can result in dangerous contaminant gas levels in a portion of the animal living space. This has been one barrier to adoption of pit-safety ventilation practices. It is not often convenient, or even possible, to relocate all of the animals because of the size of the herd and layout of the facility. For these cases, it is desirable to determine the best combination of pit-safety fan locations and pit air exchange rates that will result in satisfactory air conditions for welfare of the animals above yet ventilate the pit in a reasonable length of time for human entry. This research develops methodologies and protocols for evaluating barn air contamination hazards during positive pressure pit-safety ventilation and to demonstrate that manure pit ventilation configuration and fan capacity do influence the level of air contamination hazard in the barn. Hydrogen sulfide (H2S) gas decay was measured at several locations inside a swine nursery room during manure pit and room ventilation. A computational fluid dynamics (CFD) model of the nursery room was developed, and transient simulations of pit-safety and room ventilation were performed. Simulation results were compared to measured gas concentrations at 15 locations. Results indicated that the simulated temporal gas concentrations at 8 of 15 locations agreed favorably (within validation criteria) after adjusting measured values for a first-order instrument response.A trend observed during analysis of CFD simulation results for a given pit and barn shape and ventilation configuration (the same pit-safety fan location and flow rate with the same barn ventilation rate) with different uniform initial manure pit H2S gas concentrations (C0) suggested that the ratio of concentration (C) at each time step during ventilation was equal to the ratio between the initial concentrations inside the manure pit. It was determined that C/C0 scaling could be used to expand the results from one CFD simulation at one C0 value to a wide range of C0 values. The maximum error when comparing simulated to estimated C/C0 values was 2.5% for the global maximum H2S gas concentration over time. Simulations were performed for a 12.20 m wide 30.49 m long (40 ft wide 100 ft long) barn located above a full-sized manure pit with a fully-slotted cover. Tunnel ventilated and mechanically cross-ventilated barn configurations were studied to determine how manure pit-safety ventilation fan configuration (location and flow rate) affects the distribution of H2S gas in the barn airspace during a barn and manure pit-safety ventilation event. Simulation results were analyzed to determine the affected area in the barn and the duration of time when the concentration of H2S gas was 50 ppm or greater, the maximum H2S concentration in the barn airspace, and how much time was required to reach safe H2S gas entry levels in the manure pit. During pit-safety ventilation, the maximum concentration in portions of the airspace within both tunnel ventilated and mechanically cross-ventilated barns was equal to the initial manure pit H2S concentration, requiring animals and personnel to be evacuated from those zones when C0 50 ppm. The tunnel ventilated barn was divided lengthwise into five 6.10 m long 12.20 m wide (20 ft long 40 ft wide) quintiles for analysis. For the tunnel ventilated barn simulated in this study, animals should always be evacuated from the quintile nearest the tunnel ventilation barn exhaust fans when C0 50 ppm during pit-safety ventilation. When C0 200 ppm, the pit-safety fan location at the longitudinal and transverse centerline of the barn resulted in more contaminated area in the barn overall and in the three center barn quintiles than all other cases, making this the worst choice for pit-safety ventilation fan location for tunnel ventilated barns. However, there were large contiguous clear areas in the three center barn quintiles for all other pit-safety fan locations and flow rates, including the case with no pit-safety fan, when the initial manure pit H2S concentration was 300 ppm or lower. In general, pit-safety fan locations near the barn exhaust fans (counterflow locations) resulted in longer times to reach safe H2S gas entry levels inside the manure pit compared to the case with no pit-safety fan, and pit-safety fan locations near the barn air inlets (parallel flow locations) resulted in shorter times. Parallel flow with the pit-safety fan located along the longitudinal centerline of the barn resulted in less overall contaminated area in the barn than all other cases as well as the case with no pit-safety fan. The mechanically cross-ventilated barn was divided into five 2.44 m long 30.49 m wide (8 ft long 100 ft wide) quintiles for analysis. For the mechanically cross-ventilated barn simulated in this study, animals should be evacuated from at least portions of the quintile nearest the barn exhaust fans and the two quintiles farthest from the barn exhaust fans when C0 50 ppm during pit-safety ventilation. However, there were large contiguous clear areas in the remaining two barn quintiles for all simulated cases when the initial manure pit H2S concentration was 200 ppm or lower. All pit-safety fan locations and flow rates resulted in shorter times to reach safe H2S gas entry levels in the manure pit compared to the case with no pit-safety fan. This work demonstrates the potential for evaluating alternative pit-safety ventilation configurations to reduce the need for animal evacuation from portions of barns located above positive pressure safety ventilated manure pits. Parallel flow pit-safety fan locations were more effective for the tunnel ventilated barn, with more contamination near the barn exhaust fans and along the barn sidewalls. In general, parallel flow pit-safety fan locations with higher flow rates resulted in shorter times to reach safe H2S gas entry levels in the manure pit, but increased contaminated area in the barn airspace. Animals do not need to be removed from barns during pit-safety ventilation when the maximum initial H2S concentration inside the manure pit is less than 50 ppm. The protocols developed for this study can be used by engineers when designing and evaluating manure pit-safety ventilation systems to reduce the risk of creating hazardous conditions inside the barn during pit-safety ventilation.

Book excerpt: Lack of accidents does not necessarily mean safe operation. You may have been lucky. You may have had near misses, but fortune smiled and you had few accidents. Measuring accidents provides one segment of the safety picture, but it is a far cry from evaluating and creating overall safety. Rather than giving you accident statistics and the admonition "you need a program," Agricultural Safety shows you how to "do" safety. The book sets forth the steps you need to take to make safety a part of your everyday farming operation, such as: - Identification of key safety activities that will lead to better control of losses - Setting standards and guidelines for doing that work - Measurement of the effectiveness of the work being done in accordance with the standards and guidelines - Evaluating program progress based upon measurements taken - Correcting deficiencies based on the evaluation(s) The author covers topics such as machinery operation, maintenance and repair techniques, fire loss control techniques, the safe handling of agrochemicals, and techniques involving the handling of animals. He provides you with a step-by-step manual for the procurement, handling, and storage of agrochemicals and pesticides as well as a guide to personal protective equipment and reviews safety for "third parties" and the posting of property and public warnings. To achieve safety, the work of safety must be done, measured for efficiency, evaluated in real-world terms, and corrective action taken, as needed, in a timely manner. Many books on safety provide a list of dos and don'ts. Agricultural Safety discusses the ways and means of managing and controlling accidental loss and shows you how to build safety into your operation.

Available in PDF, EPUB and Kindle. Book excerpt: This unique compilation provides comprehensive coverage of all aspects of biogas, methane, farm recovery processes, manure digesters and processing, the AgSTAR program, landfill methane gas, and the Global Methane Initiative. AgSTAR is focused on livestock producers (typically swine and dairy farms) for implementing methane recovery systems appropriate for confined livestock facilities that handle liquid or slurry manure. Gas recovery systems and digester technologies may provide enhanced environmental (air and water) and financial performance when compared to traditional waste management systems such as manure storages and lagoons. When livestock manure that is handled as a liquid or slurry decomposes anaerobically (without the presence of oxygen), it produces biogas. In waste management systems that are designed for treatment, such as digesters and anaerobic lagoons, biogas consists of about 60 to 70% methane and 30 to 40% carbon dioxide. When these gases are collected and transmitted to a combustion device, such as an electric generator, boiler, or absorption cooler, energy is produced. The captured biogas, which is 60 to 70 percent methane, can be used to generate electricity or replace fossil fuels for other energy needs. Municipal solid waste (MSW) landfills are the third-largest source of human-related methane emissions in the United States, accounting for approximately 17 percent of these emissions in 2009. At the same time, methane emissions from landfills represent a lost opportunity to capture and use a significant energy resource. Landfill gas (LFG) is created as solid waste decomposes in a landfill. This gas consists of about 50 percent methane (the primary component of natural gas), about 50 percent carbon dioxide (CO2), and a small amount of non-methane organic compounds. Instead of escaping into the air, LFG can be captured, converted, and used as an energy source. Using LFG helps to reduce odors and other hazards associated with LFG emissions, and it helps prevent methane from migrating into the atmosphere and contributing to local smog and global climate change. LFG is extracted from landfills using a series of wells and a blower/flare (or vacuum) system. This system directs the collected gas to a central point where it can be processed and treated depending upon the ultimate use for the gas. From this point, the gas can be flared, used to generate electricity, replace fossil fuels in industrial and manufacturing operations, or upgraded to pipeline-quality gas where the gas may be used directly or processed into an alternative vehicle fuel. The goals of the Global Methane Initiative (GMI), an international public-private partnership, are to reduce global methane emissions to fight climate change, enhance economic growth, strengthen energy security, and improve local environmental quality and industrial safety. Building on experience from the U.S. Environmental Protection Agency's (EPA's) successful domestic methane emission reduction programs, GMI brings together the public and private sectors to develop projects that can reduce emissions from the agriculture, coal mine, landfill, oil and gas systems, and municipal wastewater sectors. GMI was launched in 2010 based on the strong foundation of the accomplishments of the Methane to Markets Partnership, which was formed in 2004.
