Mercury Monitor and the Multi-Gas Lab Material

Last updated on September 2, 2020

Mercury Monitor and the Multi-Gas Lab Mercury is a chemical element that is naturally-occurring and located in the earth crust. In relation to chemistry, mercury is abbreviated with symbol Hg and is represented by atomic number 80. There are various forms in which Mercury exists. They include inorganic mercury compounds, elemental mercury, and methyl mercury. Elemental mercury includes elements with no other substance combined, while methyl mercury forms after it react with carbon (Mercury Awareness Program, 2007). Additionally, metallic mercury, which is a shiny and white metal, is regularly used in fluorescent light bulbs and older thermometers. Metallic mercury disappears once exposed to air, and after heat, it turns to a colorless and odorless gas. Countless benefits, as well as negative impacts, have been put forward as they relate to Hg Monitor and MultiRAE materials.

Mercury (Hg) Monitor

Once mercury has been exposed into the air, it becomes a challenge to the environment. Mercury release is naturally occurring; however, in some cases, it is catalyzed by human activities such as the burning of coal, waste, wood, and oil. Subsequently, airborne mercury is released to the earth, which is hazardous not only to the human population but also to other habitats (Liu, Cai, & O’Driscoll, 2011). Even though mercury exits in its natural form in coal and fossil fuels, the human population is considered the main cause of the high level of mercury emissions into the atmosphere via burning fuel. Other avenues in which mercury is emitted into air include burning oil, wood, and waste products that contain mercury as an element. Lastly, burning iron ore, use of coal-fired boilers and application of technology that is used to produce chlorine are other causes of mercury air emission. Additionally, exposure to other kinds of mercury compounds like phenylmercury acetate and ethylmercury, which are used as fungicides and preservatives, leads to mercury air emission.

The human population is exposed to mercury in several ways bearing that it exists in different forms. In the United States, for example, people are exposed to mercury through consuming fish which contain methylmercury. According to research, a big portion of the world’s population has traces of mercury in their body due to products consumed (United States Environmental Protection Agency, 2017). Mercury enters to fish and shellfish through lakes and streams where they live. The amount of concentration of mercury in fish depends on what they eat, the amount of time spent in water, and their level in the food chain (United States Environmental Protection Agency, 2017). People who are at a considerable risk of consuming methylmercury as contained in fish are the ones who eat a large amount of fish on a regular basis.

On the other hand, exposures to elemental mercury occur after it has been released from containers or product. As a result, mercury stains are released into the atmosphere if the containers are not cleaned, leading to its inhalation into the atmosphere. Its prevalence becomes more serious if one lives in poorly ventilated rooms where the amount of mercury in circulation is relatively high. Other main sources of potential exposure to elemental mercury include fever thermometers, novelty jewelry, and consumer products such as switches, dental fillings, and gold mining instances (National Institute of Standards and Technology (NIST), 2000). There are various ways in which consumption and inhaling mercury negatively affect human populations.

Health effects associated with exposures to mercury depends on various factors such as forms of mercury, amount of exposure, age of a person, the time it takes, the way the person is exposed, and health of the person.  Presently, there is no accepted research that expounds the direct link between mercury and cancer. Different symptoms that indicate methylmercury poisoning include damage of peripheral vision, poor coordination of movement, impaired hearing and walking, and muscle weaknesses. Research has indicated that infants are severely affected when their mothers consume fish containing methyl-mercury. The young ones can experience effects in cognitive thinking, memory, visual-spatial skills, language, and fine motor skills.


Metallic mercury is a health hazard to the human population which has different symptoms after its exposure. They include tremors, headache, insomnia, poor mental function, and change in nerve responses. When one inhales a large amount of metallic mercury, there are high chances of respiratory problem, kidney failure, and death. Besides, contact with inorganic mercury results in damaging the nervous system as well as the gastrointestinal tract. Some of the symptoms linking high exposure of inorganic mercury are mood swings, muscle weakness, skin rashes, mental loss, and mental instability (The United States Environmental Protection Agency, 2017). Additionally, people who take water with a high concentration of inorganic mercury have high chances of kidney failure.

Mercury is used for industrial purpose considering its quality and subsequently adds up to user-friendly and customer satisfaction. Once Ohio Lumex made discoveries that have to do with a host of analyzers, analyzers systems, and continuous monitors to aid the industry reach required standards. For example, the sorbent trap sampling system was designed for Relative Accuracy Test Audits which uses the EPA approach. The system is used in power plants, stack testers, and cement kilns due to its preferred features such as sampler’s size and durability. Secondly, sorbent traps are used in manufacturing sectors. Thirdly, optical oxygen sensors are utilized in the technology industry to design different products. Benzene analyzer is used in cases involving traces of toluene and xylene to perform PPE selection (Liu et al., 2011). Dust monitors are used to regulating dust, and its easiness to install and maintain explains why it is highly preferred. Laboratory gas generators are also used in the fuel industry.


MultiRAE is one of the most preferred chemical detectors used in different industries. This preference is explained by its nature of flexibility, wireless portability that is convenient, and versatile multi-gas monitor. As a result, success in terms of easy access to instrument measurements and alarm at any particular place is traced. Due to the wireless connection feature, MultiRAE facilitates fast response rate when an incidence occurs. Other features of a well-designed MultiRaE include a 25 filed interchangeable sensor options, local and remote alarms, integrated wireless, rugged design, presence of onboard gas libraries, and dust-tight and waterproof features (Rae Systems, 2017). One hundred and ninety VOCS and fifty-five combustible gases are examples of onboard gas libraries. In addition, MultiRAE contains other key features like flappable screen, automated bump testing and calibration with AutoRAE 2, longest battery, icon-driven interface, and uninterrupted data logging.

MultiRAE is used in various ways. They include venue protection, fracking, clandestine labs, hazmat response, residential calls, emergency responses, exploration, and urban search, and rescue. Other uses include confined space entry, plant shutdown and turn-around, and environmental cleanup (Ohio Lumex, 2017). MultiRAE products include Safety Notice Advisory, MultiRae interactive DEMO, TN-148: defining the interval between calibration checks, TN-152: effects of operating conditions on oxygen sensors, MultiRAE datasheet, and AP-000: RAE system PID training outline among many others.

The use of MultiRAE is well-represented in a quick start guide. This user interface includes three main keys which are y/+, MODE, and N/-. LDC is supposed to relay information that has to do with radio connection, alarm, any real-time reading, and battery. The process of charging a MultiRAE is also well elaborated. The guideline explains that battery should always be charged to capacity before use. MultiRAE should be turned on when the instrument is off as MODE is held and later released (Rae Systems, 2017). To turn the MultiRAE off, one should press and hold MODE. During this process, fingers should be firmly pressing the keys without release. The alarm can be tested via the quick press to the Y/+ once.

The MultiRAE can be easily bump tested via utilization of Auto RAE 2 Test as well as a calibration system. Additionally, MultiRAE is supposed to be zero-calibrated which is performed using the fresh air menu button. There are two special conditions for safe use of MultiRAE system which include fitting PGM-62xx with RAE system Battery Pack type and charging it outside hazardous conditions (Fish, Stout, & Wallace, 2010). Precautions part while dealing with MultiRAE system is well captured.


In conclusion, it is evident that apart from monitor type of utilization, mercury has other various uses in different industries. Nonetheless, it has other negative impacts on the health of human beings since it is consumed in different products and inhaled from the air. Methylmercury, metallic mercury, and other mercury compounds are forms in which its exposure and risks take place. To regulate risks associated with exposure of mercury, there are different laws and acts that have been affected in a different point in time. On the other hand, MultiRAE is a chemical detector used in several industries. Some of its applications include but are not limited to residential calls, fracking, exploration, clandestine labs, urban search and rescue, and venue protection. Quick start guide inclusively elaborates how MultiRAE systems should be started, run, switched off, and precautions necessary.
