It explains what Class “A” and “B” foams are, how it works, and the benefits of using foam agents. The essay also discusses the uses of the foaming agent and their limitations with some scenarios of proper usage of Class “A” and “B” Foams, and some scenarios of not using these foams. It also discussed how Class “A” and “B” foams are ineffective with other types of fire classes such as Class “D” and Class “C” fires. Keywords: Class A, Sprinklers, Class B, Foam Agents, water-based fire system, Class D, Class C.

It explains how the knowledge of the water-based system can help firefighters mitigating any fire and control it. It also contributes to preparing for any deficiencies that might be existed in the fire systems. The case study of Manufacturing Mill Fire explains the importance of knowing the type, location, and the water-only system design on the incident action plan. Keywords: NFPA, Sprinklers, Pre-fire plan, Manufacturing Mill, water-based fire system, Incident Command.

Plant domestication timeline shows that human did significant efforts to improve crops. Breeders used pre-scientific and scientific techniques. The scientific methods evolved and breeders use new tools to map thousands of gene. They also invented strategies to screen large populations of plants. Genetic modification is a modern method of plant breeding. It has some cons and some pros that we need to evaluate them. Classical plant breeding has several techniques and processes. It used to improve crop yield, tolerance to diseases, pathogen resistance, pest resistance, and herbicide resistance of the plants. However, the classical breeding may have a crucial role in a changing environment. Climate changing and ozone-layer depletion may lead to changing of environment. Evaluation of the impacts of changing environments of plant growth, diversity and demography will help scientists to establish environmental strategies to control the loss of plant diversity.

To understand how marine life evolved, we need to study the historical geology of marine life and elemental components and processes. Historical geology studies show that fossil records are essential in order to understand the emergence of life in the marine environment. The discovery of hydrothermal vents gave the scientists vital information about the primitive life in marine. Marine biology is also crucial to identify conservation strategies of marine life. The methods of reproduction, taxonomy, and marine food webs are the tools of marine biology needed to be studied. Other important factors that help to establish conservation strategies are adaptation strategies including, for example, locomotion and propulsion, development of organisms’ parts and shape, osmoregulation, thermoregulation, reproduction system and sensory system development.

It explains the different types of the obstructions and focuses on the Microbiologically Influenced Corrosion (MIC). The essay explains the causes of MIC and how it affects the performance of the system. The essay also discusses the notification systems and their components. Each notification system has a control panel, fire detectors, and alarm output devices.
Keywords: Obstructions, Sprinklers, MIC, Alarm Output Devices, Alam Systems

It shows the importance of the residential fire sprinkler systems and the consequences of their absence. It explains the differences between the water-mist sprinkler system and the water spray system. The essay also discusses the statistics that are prepared by Steve Weatherby (2009), which shows a significant reduction in fire deaths and injuries and property loss in a home equipped with a sprinkler system.
Keywords: NFPA, Sprinklers, Residential sprinklers, Water-mist, Water Spray, Multi-family home.

The training programs should be designed to help to improve the existing culture and help new employees to digest the corporate culture. The organizations can use succession planning as a tool to implement the continuity of the existing culture and help to solve any issues that arise from the cultural change. Aon Early Career Development Program is a good example of a good succession planning. The easy argues that the internal and external blogs can be so beneficial for the organization employees to share their experience, but it should be controlled by the organization Polices and code of practices.
