Hazard administration is the recognizable proof‚ evaluation‚ and prioritization of dangers ( as the impact of instability on goals) trailed by facilitated and conservative utilization of assets to limit‚ screen‚ and control the likelihood as well as effect of deplorable occasions or to augment the acknowledgment of chances. Hazard administration’s goal is to guarantee instability does not avoid the attempt from the business objectives. Value beat is a chain marked down departmental stores crosswise

1. INTRODUCTION Electrical substation for distribution system is the main supply to convert the high voltage (HV) to low voltage (LV) and the place where load are distributed to the consumers. In Malaysia‚ Tenaga Nasional Berhad Distribution (TNBD) used the 33/0.433kV‚ 22/0.433kV‚ 11/0.433kV and 6.6/0.433kV voltage system for the electrical system to supply for domestic consumer and industrial consumer such as factory which will supplied directly from Transmission Main Intakes (PMU)‚ Main Distribution

Electrical technology – assignment 4 Properties of electrical materials and Effective use of technology P.5. Describe the properties and a typical application of a solid and a liquid or gas electrical conductor. A conductor is a material that allows free movement of electrons and therefore allows easy flow of electricity. Most conductors are metals. A common metal used as a conductor in electrical technology is aluminium. It is used quite a lot as it cheap‚ lightweight and in abundance compared

conveniently designed conductive disks allow the electrical load of the generator to be fed either with alternating current or direct current. the loop terminals is sinusoidal with zero mean value (Fig. 2). Its frequency is equal to the number of revolutions per second executed by the loop. Each terminal of the loop is connected to a metallic ring. The contacts with rings are made by means of fixed brushes. If the brushes are connected to an electrical load‚ an alternating current will be established

Environmental Hazards December 6‚ 2012 Environmental hazards can have many effects to one’s health. It has the potential to threaten the surroundings of a natural environment and harmfully affect people’s health. It can cause health issues to plants‚ minerals‚ or animals. Some hazards have the potential to be poisonous to the environment. Some examples are oil spills‚ which can cause fish or any animal living in the water to die. There are earthquakes‚ tsunamis‚ and floods. Environmental hazards are

Anthropogenic hazard Anthropogenic hazards or human-made hazards can result in the form of a human-made disaster. In this case‚ anthropogenic means threats having an element of human intent‚ negligence‚ or error; or involving a failure of a human-made system. It results in huge loss of life and property. It further affects a person’s mental‚ physical and social well-being. Sociological hazards Crime Crime is a breach of the law for which some governing authority (via the legal systems) can ultimately
