...Safety Awareness in Electrical Engineering It is important for students studying to become electrical engineers to be aware of electrical safety measures and hazards. There are several severe, even life-threatening hazards that one could encounter when among electrical equipment. Two main dangers related to dealing with electrical equipment shocks and burns are overloading outlets with too many devices, and neglecting to implement the usage of a Ground-Fault Circuit Interrupter. While outlets are designed to handle multiple plugs, it is crucial to know that they do have limitations as far as what they are capable of supporting. Various dangers can occur by overloading an outlet. Risks of electrical fires are increased when two or more appliances are plugged in at once, or when extra electricity is required by means of an extension cord. This is also the reason why major appliances such as refrigerators and dryers should be plugged directly into their own outlet; they are heavy power users. Although most homes and appliances have fuses as a form of safety to prevent fires, people should still be aware of the amount of power can be placed on each outlet or circuit. A safety procedure that could potentially be life-saving is the usage of a ground-fault circuit interrupter (GFCI). It protects people from electrical shocks by monitoring the amount of current flowing in a circuit (from hot to neutral), and thereby locating a loss of current. If it senses an imbalance, the...

Abstract The subject of electrical hazards analysis has been recognized by a small segment of the electrical industry for many years. The petrochemical industry and many government institutions have performed research on this subject for over twenty years. For the most part however, the electrical industry, at least at the user level, has largely ignored the subject, essentially reacting to catastrophic accidents, rather than proactively trying to predict and prevent them. Recent changes in consensus standards, along with a better general understanding of the seriousness of electrical hazards have resulted in a renewal of interest in the subject. As the awareness of electrical hazards increase many are puzzled by phrases like; “Limited”, “Restricted”, and “Prohibited Approach...

...The ‘Assumed System’ – The analysis of the problem has been carried out for the network wherein the neutral is earthed at distribution transformer end and along the distribution system (at LT feeder pillars A, B as shown below). It is connected to earth at two separate and distinct points. The neutral of a main-line cable is earthed at both ends via LT feeder pillars (A & B), while neutral of a service cable is earthed at one end (via LT feeder pillar B) and not at meter cabin end with due consideration of safety issues. Earthing of neutral (which is normally a current carrying part) and consumer earth wire (which is normally a non-current carrying part) may get electrically connected due to space constraints at consumer end. In real life, due to lack of inspection and poor maintenance, the earthing may get open and likely to remain unnoticed. In case of a phase to neutral cable fault, there is a likelihood of the consumer earthing and thereby consumer house-hold equipments get charged to a voltage unsafe to human life. Hence, it is always preferable not to earth the neutral at consumer (meter cabin) end. The Single Line diagram of the ‘Assumed System’ is as – [pic] I.E. Rule 1956, section 61(a) requires that “Neutral conductor of a 3 phase, 4 wire system shall be earthed by not less than two separate and distinct connections with a minimum of two different earth both at the generating station and at the sub-station (Neutral Earthing at distribution centre)...

...and prevent it from buckling, when it is subjected to bending loads. Stringers give a large increase in the stiffness of the skin under torsion and bending loads, with minimal increase in weight. Other than that, fuselage must be able to resist bending moments caused by weight and lift from the tail, torsion loads caused by fin and rudder. Pressurization can lead to tension or compression of the floor-supports as well. The structural strength and stiffness of the fuselage must be high enough to withstand these loads. According to the British Civil Airworthiness Requirement, safety factor of at least 1.5 times the normal working load for aircraft fuselage structure must be used. Failure is catastrophic, the limit load occurs during every flight and the fuselage is not only subject to pressurization forces. The static strength of the fuselage therefore incorporates a larger safety factor. A reduced factor of safety from the stated factor will preclude failure due to creep and provide adequate protection against tear propagation. Besides, the structure must be able to support limit loads without permanent deformation. At any load up to limit loads, the deformation may not interfere with safe operation and this applies in particular to the control system. The structure must be able to support ultimate loads without failure for at least three seconds. Another important construction factor of fuselage is protection of passenger in crash. Transport aircraft carrying as many as 800 passenger...

JEEVANANDA S CASE – FIRE IN A BANGLADESH GARMENT FACTORY Fire in a Bangladesh garment factory Introduction This case talks about fire in a garment factory which was located near capital Dhaka in which 112 people were killed and several hundreds were injured. This happened in November, 2012. The main reason for the fire was an electrical short circuit. The factory did not have required safety equipment’s and other safety measures were not followed by the factory which were mandatory as per the law of the country in order to ensure safety towards your employees due to which employees were not able to evacuate the factory at time of fire and lost their lives. Now the question is that who should be blamed for this mistake i.e. the factory owner, Walmart, or the customers. No one the ethical employer can sacrifice live for the low cost of production or earn more by using unethical measures. This case was also analyzed by “clean clothes campaign“and they also had their view points about various mistakes or unethical measures which these factories are following in order to make huge profits. Details about factory – The factory was owned by Tazreen Fasions Ltd., a subsidiary of The Tuba Group who is a large Bangladeshi garment exporter with clients like Walmart, Carrefour, Li and Fung. The factory was opened in May, 2010 which used to manufacture T-shirts...

...Risk Assessment It is important that children are provided with safe and secure environments. Child-minders need to ensure that, a risk assessment is put in place, and therefore they make necessary changes to secure their safety at all times. Child-minders must ensure that the home, indoors and outdoors, are safe and secure. This should include appropriate measures such as including indoor and outdoor security. For example, ponds, drains, pools should be made safe or inaccessible to children. Child-minders should be aware which doors are locked or unlocked, how to use door alarms and security systems, formal identifications. There should be fireguards in place and fitted securely on all fires or heaters so children don’t burn themselves and cause damage. Also radiators or thermostats should be set at an appropriate/safe temperature around 18 degrees. There should be window locks on all windows in all rooms so children don’t trap their fingers. If you don’t put window locks on the upstairs windows children are not allowed up there due to the registration and there will be some areas which are unsafe to go in to. Also in the garden if you have a shed that has glass windows there should be glass film to cover them so they don’t break this can lead to cuts. There should be socket covers in all plugs in every room, this could cause harm if there isn’t any covers because children should get electrocutions. The hazards of plug in air fresheners carry the risk of a choking...
