Because IR radiation falls outside that of visible light (the radiation spectrum to which our eyes are sensitive), it is invisible to the naked eye. An IR camera or similar device allows us to escape the visible light spectrum and view an object based on its temperature and its proportional emittance of IR radiation. How and why is this ability to detect and visualize an object’s temperature profile important in maintaining systems or components? Like all predictive maintenance technologies, IR tries to detect the presence of conditions or stressors that act to decrease a component’s useful or design life. Many of these conditions result in changes to a component’s temperature. For example, a loose or corroded electrical connection results in abnormally elevated connection temperatures due to increased electrical resistance. Before the connection is hot enough to result in equipment failure or possible fire, the patterns are easily seen through an IR imaging camera, the condition identified and corrected. Rotating equipment problems will normally result in some form of frictional change that will be seen as an increase in the component’s temperature. Faulty or complete loss of refractory material will be readily seen as a change in the components thermal profile. Loss of a roof’s mem- brane integrity will result in moisture that can be readily detected as differences in the roof thermal profile. These are just a few general examples of the hundreds of possible applications of this tech- nology and how it might be used to detect problems that would otherwise go unnoticed until a component failed and resulted in excessive repair or downtime cost.

ENVIRONMENTAL BEST PRACTICES FOR HIGHWAY MAINTENANCE ACTIVITIES OCTOBER 2010

ENVIRONMENTAL BEST PRACTICES FOR HIGHWAY MAINTENANCE ACTIVITIES OCTOBER 2010

Many aspects of highway maintenance are routine, and carry little risk of environmental harm. However, some highway maintenance activities have the potential to cause negative physical, chemical and biological impacts to the surrounding environment. These impacts to fish and wildlife habitats and species, and water, air and soil quality can be significant and enduring. Site-specific factors such as proximity of the work site to environmentally sensitive areas, the scale of the work, and the type of materials used can influence the level of risk that a maintenance activity poses to the environment.

Sustainable Operation of Marginal Fields in Nigeria: Opportunities, Challenges and Best Practices

Sustainable Operation of Marginal Fields in Nigeria: Opportunities, Challenges and Best Practices

_________________________________________________________________________________________ Abstract For over forty years, Nigeria has witnessed the transformation of the economy from agriculture-based to oil- based. Evolving the local content initiative in this oil-based economy, the Federal Government of Nigeria in 2003, awarded 24 marginal fields of the available 116, with over 2.8 billion barrels of crude oil reserves, to indigenous companies, for development and exploitation. This initiative has two main objectives, namely, the greater involvement of local companies in the upstream sector of the petroleum industry towards a higher level of indigenization, and growing more reserves of petroleum assets. However, by the end of June 2013, less than 30% of the awarded fields are producing petroleum assets, crude oil and/or natural gas and its derivatives. In this paper, we present opportunities to sustain corporate responsibilities – social and economic, and investigated challenges that confront the local operators of these fields. Basic roles that will improve the contribution of the operators of marginal fields in Nigeria towards value creation are suggested for optimization. We posit that proper business engineering and the monetization of natural gas assets in these fields will be major best practices for value creation. We believe these will significantly impact on the sustainable operations of the marginal fields, and thus, ensure the success of the marginal field initiative, especially, in the growing of natural gas reserves, a key component for power generation in Nigeria.

Best Management Practices for Agrichemical Handling and Farm Equipment Maintenance

Best Management Practices for Agrichemical Handling and Farm Equipment Maintenance

has a discharge port (not recommended), make certain that it is closed and locked except when uncontaminated rain water is to be drained. If a discharge port is used, a spring loaded valve is the best method to prevent the port from being inadvertently left open. The first line of management is to minimize the possibility of a discharge and the need for disposal. For rainfall, if the containment volume is adequate, evaporation of accumulated rainfall will often be suffi- cient. Critical levels at which discharge is considered should be established for each facility and the levels marked on the containment wall. This will prevent frequent and unnecessary discharge of small volumes.

characteristics of maintenance vehicles or any other vehicle that regularly operate on the trail. Comparisons were made between the proposed design procedures and the performance of trails surveyed in northern, central, and southern Illinois. The results of the survey indicated that the proposed design procedure should produce a structural trail section that performs well over time. Detailed life cycle cost analyses were conducted for different trail designs and different pavement materials for a design period of 20 years. The analyses showed that relative costs were influenced by surface type and maintenance strategies that were required based on the particular surface type used.

Best Practices for Winter Maintenance Roadway Deicer Applications in the State of Nebraska

Best Practices for Winter Maintenance Roadway Deicer Applications in the State of Nebraska

city/county respondents reported that their treatments were very effective. It seems reasonable that a best practice involving 10% Ice Slicer should be standardized for use by City/County maintenance workers for treating compacted snow. Table 8 represents a complete list of all the respondents from NDOR for Scenario 3 that used Ice Slicer. Some of the “very effective” treatments have a smaller application rate than some of the “somewhat effective” treatments. This reveals that the difference between “very effective” and “somewhat effective” is rather subjective. This also shows that different winter maintenance professionals may have different goals. For instance, winter maintenance teams may apply a large quantity of 10% Ice Slicer with sand/gravel to only curves and accident-prone areas to increase the traction and to initiate melting. A best practice using solid deicer might consist of 10% Ice Slicer with road salt at 150-200 lbs/lane mile with a pre-wet of Apex at 9-12 gal/ton. This practice has an estimated cost of $18.71-$24.95/lane mile. After reviewing literature and interviewing a few

PASSPORT II DISPLAY PANEL INSTALLATION Before mounting the Passport II digital display panel touch pad, consider the location. The air sensor built into the display panel will provide excellent room air temperature sensing given a proper installation. The display panel should be mounted on an inside wall, slightly higher than mid-height of the cabin, in a loca- tion with freely circulating air where it can best sense average temperature. The cut out size for the display panel is 3” wide by 2”( high. Do not mount the display in direct sunlight, near any heat producing appli- ances or in a bulkhead where temperatures radiating from behind the panel may effect performance. Do not mount the display in the supply air stream. Do not mount the display above or below a supply or return air grille. Do not mount the display behind a door, in a corner, under a stairwell or any place where there is no freely circulating air. Mount the display within display cable length (custom lengths available) of the air conditioner. Plug the display cable (15”/4.6m standard length with 8-pin connector) into the circuit board in the electric box and into the back of the display panel. Secure the display panel to a bulk- head with the adhesive strips provided. Clean the mounting surface with isopropyl alcohol only prior to placement (test alcohol on hidden portion of surface first). If the adhesive strips cannot be used directly on the bulkhead then use the plastic bulkhead adapter. The bulkhead adapter (sold separately) is mounted to the bulkhead with screws and the display panel is secured to the adapter with adhesive strips. Do not use a screw gun and do not over-tighten screws when mounting adapter.

Important Responsible Refrigerant Practices Trane believes that responsible refrigerant practices are important to the environment, our customers, and the air conditioning industry. All technicians who handle refrigerants must be certified according to local rules. For the USA, the Federal Clean Air Act (Section 608) sets forth the requirements for handling, reclaiming, recovering and recycling of certain refrigerants and the equipment that is used in these service procedures. In addition, some states or municipalities may have additional requirements that must also be adhered to for responsible management of refrigerants. Know the applicable laws and follow them.

Operation and Maintenance Instructions

Operation and Maintenance Instructions

Depending on outdoor conditions, the dry coil on the WDW should be cleaned at least twice a year. If the unit is located near trees, construction, etc., the required cleaning may be more frequent. Per our standard unit maintenance guidelines shown on pages 8 & 9, the coil should be visually inspected monthly along with inlet louvers and inlet screens. The best cleaning solution for the dry coil is plain water. If the coil has been maintained and cleaned at regular intervals, water is sufficient to remove dirt and debris from the fins. Heavy build up on the exterior of the fins can be removed with a brush. If a pressure washer is used, make sure the equipment is set to a low pressure setting and that the nozzle is set to the fan spray, not stream, otherwise damage to the fins could result. The best method of cleaning the coil is from the inside out. Spraying water from the outside repeatedly can cause a buildup of debris and airflow restriction.

The 2800 and 2810 use a "pusher" fan which pull air in through the sides of the engine hood and pushes it through the coolers and the lou- vered grill (Fig. 57). This system allows the air to be "filtered" through the hood's screening be- fore it reaches the coolers. This also keeps hot air and dust off the operator. Depending on the conditions the coolers will most likely need to be cleaned at some point. Since any debris will collect on the engine side of the coolers the de- bris must be cleaned by forcing the debris off from the other side of the coolers. Air or water under pressure works best for thorough clean- ing.

When choosing what to plant, consider which plants will do best in the local soil type and which ones can cope best with regular daily doses of nutrient-rich wastewater. These plants must be able to cope with nutrients such as sodium, chloride, nitrogen and phosphorous. Many Australian natives can’t cope with high levels of these nutrients. Generally speaking, the best plants to grow on the disposal area are a mix of summer and winter grasses. Appendix Three has a list of suitable vegetation to be planted down slope of the trench area.

Guide to Best Practice Maintenance & Operation of HVAC Systems for Energy Efficiency

Guide to Best Practice Maintenance & Operation of HVAC Systems for Energy Efficiency

2.4.4 PRODUCE MAINTENANCE SPECIFICATION It is essential for the Maintenance Specifi cation to be tailored for the requirements of a building. Customised maintenance schedules and task specifi cations based on guides such as AIRAH DA19 must be developed for the building, together with the necessary performance or condition based requirements specifi c to a building’s HVAC Systems. The task of preparing a comprehensive maintenance specifi cation for a building that has been poorly maintained must not be underestimated. It will require resources from technical, administrative, fi nancial and contractual backgrounds. It will be necessary to have a good knowledge of how the building must operate in order to meet the requirements of the Building Owner and the Occupants. Also important will be an appreciation of the Facilities Managers strategy for delivering best practice maintenance & operation for the building, including maintenance budgets. It is unlikely that adequate funding will initially be available to replace all obsolete equipment. Therefore, the replacement of plant will have to be prioritised and planned in line with the expected availability of funding and the anticipated useful working life of the equipment. Unless the required skills for compiling the maintenance specifi cation are available in-house, this task is best performed by a consultant with knowledge of HVAC maintenance.

Best Practices in Land Bank Operation

Best Practices in Land Bank Operation

One of the newest and most comprehensive land banks in operation today is the Genesee County Land Bank Authority (LBA), created in 2002 as a result of an inter-local agreement between Genesee County and Flint, Michigan, actually crafted before the wider enabling legislation was passed in Michigan in January 2004. The Land Bank “Fast Track” Act further enables local governments to create land bank authorities with independent powers to acquire, hold and distribute vacant, abandoned and tax-delinquent properties. Genesee County LBA obtains properties almost exclusively through tax foreclosure, but intends to begin accepting gifted properties as well as purchased parcels in order to

Best practices for public universities building maintenance

Best practices for public universities building maintenance

Nevertheless, despite the fact that university building requires maintenance especially during the operational phase, yet some university management unable to adheres to the requirement. Some existing universities do not observe strict maintenance schedules exposing their facilities to defects, that accelerate the decay of the various building members which eventually calls for the construction of new buildings and/or the demolition of the existing facilities. Although, according to Lateef et.al (2011), the construction of new building helps to upgrade educational facilities and provide a better quality of education yet, maintaining existing building should be the priorities to ensure the existing environments is conducive and adequate for learning. Besides, demolition is usually a technical or economical aspect (Lateef et. al., 2010; Zulkarnain et. al., 2011; Olanrewaju et al., 2015). Hence, it requires more financial supports compared to maintaining the existing building.

Ø improve their quality of life (Dazord, Mino, Page and Broers, 1998, 235). For pregnant women who are dependent on opioids, receiving methadone maintenance treatment, combined with adequate prenatal care, decreases obstetrical and fetal complications (National Consensus Development Panel on Effective Medical Treatment of Opiate Addiction, 1998, 1939). Methadone protects the fetus from erratic opioid levels and frequent opioid withdrawal symptoms, which are common among pregnant women who do not receive treatment for their opioid dependence (Finnegan; Kaltenbach et al., as cited in NIDA, 1995, 1-32, 1-33). Methadone maintenance treatment has substantially higher retention rates (68% after three months) compared to outpatient counselling without methadone (36%) or residential programs without methadone (45%) (Hubbard et al., as cited in Brands and Brands, 1998, 2).
