Oxygen for Life

Oxygen for Life. To what extent it's essential to monitor it for a safe working place ?
Oxygen concentration in Air is 21%. However oxygen can be displaced by other gases depending on the environment you are in.
Oxygen displacement or deficiency shall be due to leaking materials from storage tanks, natural gas lines, process valves etc. 
Decomposing organic matter, such as animal, human or plant waste, produces methane, carbon monoxide, carbon dioxide and hydrogen sulfide that displace oxygen. 
When Oxygen level falls below 19.5%, health hazards may occur, with few breaths of oxygen deficient air leading to suffocation or even unconsciousness. 
Confined spaces prohibit natural ventilation preventing gases from escaping. Explosive and toxic gases, including hydrogen sulfide and carbon monoxide, combined with a lack of oxygen, are the cause of most confined space accidents.
By tracking Oxygen levels, gas leaks can be detected eventhough leaking gas cannot be seen or smelled.
To facilitate the safety of human lives and plant, Portable and Fixed gas detectors are available which can monitor and keep a log on the gas levels with provision to set safety Alarms. Analyzing the logged data of gas monitors can help in identifying oxygen depleted zones helping in eliminating any untoward incident.
In case of confined space portable detectors with pump should be used to suck the air to evaluate presence of Toxic gases, before entering the confined space.
Happy Learning.

ISO 50001 - Energy management

ISO 50001 - Energy management Using energy efficiently helps organizations save money as well as helping to conserve resources and tackle climate change. ISO 50001 supports organizations in all sectors to use energy more efficiently, through the development of an energy management system (EnMS). ISO 50001:2011 – Energy Management System ISO 50001 is based on the management system model of continual improvement also used for other well-known standards such as ISO 9001 or ISO 14001. This makes it easier for organizations to integrate energy management into their overall efforts to improve quality and environmental management. ISO 50001:2011 provides a framework of requirements for organizations to: Develop a policy for more efficient use of energy Fix targets and objectives to meet the policy Use data to better understand and make decisions about energy use Measure the results Review how well the policy works, and Continually improve energy management.  Cer...

Life of Bearing

Life of Bearing depends on Loading. Static loads have constant magnitude and direction where as dynamic loads, vary in both magnitude and direction. Misalignment is an important source of excessive static load. Belt drive is another source of static load. Rotor malfunctions, Unbalance, rub, or aerodynamic or fluid-induced instability can produce excessive dynamic loads. Coupling malfunctions may introduce excessive static and dynamic loads. Portable Vibration Analyzers or Online Vibration monitoring systems can help in identifying faults that can be caused due to overloads well in advance facilitating predictive maintenance.

Measuring Altitude..

Flying High ?...........At what Altitude ? You can find the Altitude by measuring pressure. Interesting ...? Read to know more.. Atmospheric pressure is caused by the gravitational attraction of the planet on the atmospheric gases above the surface. The standard atmospheric pressure or Barometric pressure at sea level on the Earth is 1013.25 mBar or 760mmHg. Pressure on Earth varies with the altitude of the surface. Atmospheric pressure decreases smoothly as the altitude increases. Altimeters measures absolute pressure to indicate the Altitude. At this point it's important to understand the difference between Absolute pressure and Gauge pressure. Absolute pressure uses absolute zero as its zero point, while gauge pressure uses atmospheric pressure as its zero point. Clear ? Due to varying atmospheric pressure, gauge pressure measurement is not precise, while absolute pressure is always definite. Hence for applications like Aerospace, Flight Instrumentation or Vacuu...
