The paper "Hazardous Properties of Chemical Substances" highlights that Trinitrotoluene melts at a temperature of (80 °C or 176 °F), which is far much lower than its explosion point. TNT does not absorb or dissolve in water making it suitable for use in humid environments. …

Polyacrylonitrile (PAN) is a member of acrylic resins. The products of combustion of materials made from polyacrylonitrile (PAN) include Hydrogen Cyanide (HCN), Carbon monoxide (CO), carbon dioxide (CO2), acrolein and formaldehyde among others (Patnaik, 2007). Trinitrotoluene (TNT) is the most preferred explosive by the military because it is insensitive to shock and friction thereby minimizing the possibilities of unintentional detonation, unlike other explosives like nitroglycerine, which are more sensitive and prone to accidental blast. It is also more stable than other high explosives. The first property is that polymeric materials are stiff because they are constituted of very high mechanical features to their density. They are also exceptional thermal insulators. Polymeric compounds or materials are inflammable. This is because they are organic materials and further, cellular materials constructed of the flammable matrix such as polymeric foams, are more susceptible to fire than their equivalent concrete materials as a result of the insulating effect of their cellular structure, which amplifies the temperature at the heating exterior. Consequently, this leads to pyrolysis of materials worsening fire behavior than would have been with solid materials. The gas used in the cells may also stimulate combustion when it is combustible.
...? Runway Properties Runway properties Introduction The landing process of a plane involves several procedures and phases different from the other sections of the flight. The pilot plans for three issues, which include the approach, the landing and the go around process. The planning process is also to determine the traffic pattern a few miles away from the airport. While approaching the airport during landing, the pilot maintains the appropriate angle by controlling the pitch angle and the glide slope angle (Civil Aviation Authority of New Zealand 2011). There are two categories of landing distance; the actual landing distance, and the required landing distance. The actual landing distance is the total distance taken in landing... Runway...
...Running Head: SKIP NAVIGATION LINKS Skip Navigation Links Hazardous materials (HAZMAT) are the materialsthat pose as a threat to the environment or human health if released in large amounts. Incidences related to hazardous materials are normally complex in the public safety industry. Some of the risks that may arise due to the use of hazardous materials are; a fire hazard, an explosion, threat or a chemical gas threat. They occur due to the logistics involved in the response and operations that have to do with the way multiple units function at a scene .The multiple functions involve contraction and expansion as well as due to weather changes.
...Running head: Discuss the Role of the Occupational Physician in Implementing The COSHH Regulations Since the introduction of the Health and Safety at Work Act (HASAWA) in 1974 there has been increasing legislation on health and safety. Landmark regulations stemming from this which have had an impact on many industries are the Control of SubstancesHazardous to Health (COSHH) Regulations 1988, the Noise at Work Regulations 1990 and the 'six pack' of regulations emanating from the European Community Framework Directive:
1. Management of Health and Safety at Work Regulations
2. Work Equipment Regulations
3. Manual Handling of Loads Regulations
4. Workplace Health, Safety and Welfare Regulations
...consumption. It has been analysed that in order to stop alcoholic consumptions, there can be three steps namely primary, secondary and tertiary. Primarily, one takes measure towards educating youth. Education about alcohol health hazards and its consequences during early age can help to alert children from initiating step towards drinking and smoking. Secondary step involves taking help from parents and government regulations. And territory measure is linked to medical treatment of alcohol abused individuals (University of Missouri – St. Louis, n.d.)
Nurses can also play a major role in stopping alcoholism by assisting individuals with treatments for withdrawal of alcoholic symptoms (University of Maryland, n.d.).
...Physical and ChemicalProperties of Methylene Chloride
Physical and ChemicalProperties
Methylene chloride, also known as dichloromethane (DCM) is an organic compound with the chemical formula CH2CL2. It is a colorless, volatile liquid with a characteristic sweet aroma. It has a boiling of 40 oC (104 oF) and melting point of -97 oC (-142.6 oF). It has a vapor pressure of 47 KPa (@ 20 oC), and a relative vapor density of 2.9 (air = 1). It is soluble in methanol, diethyl ether, n-octanol, and acetone, partially soluble in water.1
General hazards from use of Methylene Chloride
Methylene chloride is described as very...
Fungicides are chemicalsubstances that are widely used to compromise the growth of pathogenic fungi. It’s applied on the surfaces of the plant and can work locally or systematically. Fungicides also exhibit different degree of action; some can be used to control a wide range of fungi hence referred to as wide spectrum or can only be used to control specific species of fungi termed as narrow spectrum fungicide.
Mode of action
The fact that fungicides can control a wide range of fungi elicit the question of how this happens, some of the advanced reasons as to how the fungicides work include the following; there are specific fungicides that impairs...
...Hazardous Waste The continued ignorance by the responsible s and individuals in relation to environmental conservation result to disposal of hazardous waste disposal to the environment and hence leading to environment calamities. Environmental laws like the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980 and the Resource Conservation and Recovery Act (RCRA) of 1976 compel us to environmental conservation. This paper will seek to answer questions relating to the Love canal case and the Ivory Coast.
Summary of Love Canal Case
Love Canal was an immediate neighborhood in the Niagara Falls in the city of New York. The site initially belonged to Hooker...

2. Impact of hazardous health care wastes
2.1 Impact on health
Health care hazardous waste exposure can lead to disease or injury. The hazardous attributes of the health waste may be due to several characteristics. These include genotoxic characteristics, radioactivity, containing infectious agents, containing sharps, containing hazardous or toxic pharmaceuticals or chemicals. The impact of the hazardous health care waste depends on the risk level. Every person with an exposure to...
...and that is why their sources are not specified under the F-list category (EPA 2008, 5). On the contrary to the F-list, the K-list of hazardous waste include particular solid wastes coming from specific industries (EPA 2008). The P-list as well as the U-list includes the wastes from commercial chemical products. Commercial chemical products have the generic names, container residues, spill residues, and off-specification species. However, the P-list and U-list are differentiated from each other by its effect: P-list includes acute hazardous wastes, while U-list includes toxic wastes (EPA 2008).
In addition to the EPA’s listed wastes, there are identified some other types...
...Chemical and physical properties of carbon-fibre reinforced composites
Composite materials are materials that constitute two or more materials with significantly different chemical and physical properties merged together. These materials are blended together in specific ratios to produce materials that that are different from the original materials based on chemical and physical properties. There are many important reasons behind the desire to have composite materials. These include, the need for stronger materials, the need for lighter materials to be used in automobile and aviation industries, wind turbines and the gradual rising need...
