Extract of sample "Chemistry of hazardous material"

Chemistry of Hazardous Materials Compounds refer to substances that are made up of more than one element or compound. The elements or compounds are combined by specific formula, in ratio, and for each compound, the percentage composition of each of its component bears a relationship to the molar mass of the involved elements and the involved mole ratios.
Percentage by Mass of Sulfur Trioxide If Oleum Is Expressed As 3H2SO4.5SO3
Using molar masses and the mole ratio of Oleum, the percentage composition of sulfur trioxide can be obtained as follows:
The relative molar masses of the involved elements are
H= 1
S= 32
0= 16
Therefore,
mass of 3H2SO4 = 3(1*2+ 32+ 16*4)= 3(2+32+64)= 3*98= 294
and
mass of 5SO3 = 5(32+ 16* 3)= 5(32+ 48)= 5*80= 400
From the formula, percentage composition of x = mass of x/mass of the compound.
Therefore, percentage composition of sulfur trioxide = (400/594)*100 = 67.34 percent

Potential Hazardous Features Associated With Concentrated Sulfuric Acid
One of the potential hazards of sulfuric acid is its corrosive nature. This leads to wearing out of material surfaces and is widely experienced in industrial processes that use the concentrated acid. Care must, therefore, be taken to protect materials and equipment from the acid. Another potential hazard of concentrated sulfuric acid is its reaction with water to generate heat – an effect that can cause burns when the acid reacts with water in the skin as well as in industrial settings. Concentrated acid also reacts with organic acids to generate heat and carbon monoxide – products that adversely affect the skin and the eye (Turkington, 2009).

...Chemistry of Hazardous Materials Chemistry of Hazardous Materials A) White phosphorus also known as yellow phosphorus requires safety measures like wearing gloves while handling because of the significant hazard it can cause to its user. This allotrope is tremendously toxic and can be lethal. Moreover, white phosphorus can cause deep slow healing burns and is highly inflammable and reactive to the extent that a fire can erupt, however, while burning white phosphorus can also cause damage to the kidneys, heart, or liver. Furthermore, prolonged skin exposure to phosphorus can cause dermatitis. Therefore, in order to avoid...

...Chemistry of Hazardous Materials Affiliation: Oxygen is one of the many gases freely found in the air. This gas can be distilled from air and cooled into a liquid form (Beeson & Smith, 2007). Storage of liquid oxygen requires special storage tanks and a very cold environment in order to maintain the necessary temperatures that keep it liquid form. Oxygen is a very volatile gas and can easily change from the liquid form to a gas at low temperatures. In its liquid form, the gas is highly concentrated and unstable. Liquid oxygen is primarily used in hospitals and for propulsion purposes. The hazardous aspect of liquid oxygen is derived from the fact that oxygen accelerates...

...should be covered so no spark occurs. These transports should not be left alone. Like other hazardous materials, explosive transports shall be clearly marked as such. Finally, the Department of Labor (2012) requires a working fire extinguisher that drivers are trained to use in the transports. Explosives are different from other hazardous materials due to the mass destruction caused. For example, an explosion can destroy a road, railway, or ship and everything in the vicinity. A toxic gas leak can lead to evacuations, but can be cleaned up with little or no life loss. The property damage is less as well. Once something explodes it cannot be taken back. It damages,...

... and other high explosives, and their ensuing explosion that caused the explosion of the PETN in the neighboring room. Based on the reconstruction of evidence conducted by the U. S. Chemical Safety and Hazard Investigation Board, apparently one worker left in the booster room around 50 to 100 pounds of base material made up of TNT and other high explosives in a pot. As no other worker or operator utilized the base material, it solidified due to the extremely low temperature on the outside. The next day, while assuming that the base material in the pot had been used, he may have turned on the motor to the agitator blades right away without checking whether the pot was empty or not. This triggered the first explosion. The reason... Sierra...

...Hazardous Material Management and Hazard Communication Hazardous Material Management and Hazard Communication According to Occupational Safety & Health Administration (OSHA), all the employers who have hazardous chemicals in their places of work need to effectively prepare and implement a well-written hazard communication program (Aldrich, 2009). It is necessary to this because it is one of the ways of protecting employees from hazardous chemicals that can cause sensitization, reactivity, irritation, corrosion, carcinogenicity and flammability to the body. It is for this reason that the...

...THE OSHAs HazCom SIGNAL WORDS THE OSHAs HazCom SIGNAL WORDS The OSHAs HazCom (Occupational Safety and Health Administration Hazard Communication) normally set standards on hazardous chemical labeling requirements so as to protect employees from toxic and hazardous chemicals. It normally does this by coming up precautionary statements, hazard statements, signal words, hazard pictograms that guide the handling and use of certain chemicals. Signal words are an important part of the labeling requirements of hazardous materials. They are used to indicate the degree of severity of a hazard. There are only two signal words namely “DANGER” and “WARNING.” “DANGER” identifies chemicals that present a greater... and...

The Difference between Hazardous Waste and Hazardous Material

...Hazardous Waste and Hazardous Material College: Hazardous Waste and Hazardous Material A hazard is a source of potential damage, harm or even adverse health impacts on living things or on something under given working conditions. A hazard can cause harm or adverse effects to anything it gets in contact with such an individual’s health or an organization’s property. At times, a hazard can be termed as being the actual harm or the health effect it caused. For instance, tuberculosis can be termed as a hazard by some people but the TB-causing bacteria is the one that should...
