Electrical safety management

The use of the term so far as is reasonably practicable implies that an assessment of the risk must be carried out before a judgement can be formed on whether or not a measure is reasonably practicable. Whereas the need for a risk assessment is not explicitly laid out in electrical safety legislation, it is explicitly a requirement of the Management of Health and Safety at Work Regulations. So risk assessment practices and procedures are a cornerstone of electrical safety management practice.

In general, there are two different architectures for BMSs namely, decentralized systems and centralized systems. These two architectures are illustrated for an electric vehicle (EV) application in Fig. 8.3 (decentralized) and Fig. 8.4 (centralized). In the decentralized system (Fig. 8.3), the individual BMS tasks are located in different devices. The charge control is part of the charger, the discharge control is part of the EV drive system, the battery state determination is carried out within a range meter, and so on. Some BMS tasks must be implemented in more than one device, especially in the case of safety management. Normally, there is little or no communication between the devices, so an optimized operation is not possible. Another disadvantage is that the battery-relevant control functions are located in different devices. Thus, each device must be adapted to the particular battery used. 

In the case of a BMS for an electric vehicle, the tasks of the safety-management system are ...

This paper describes a new nuclear power system which can be used for a greater variety of applications. The 4S liquid metal reactor has high inherent safety and passive safety characteristics. It is also easy to operate, maintain and inspect, faster to construct, more flexible in location, requires less initial investment, and is better suited to electrical grid management. The reactor offers a new route through which to expand the use of safe nuclear technology in the world. 

Fears over the effects of privatization on nuclear safety have been responsible for some of the concerns about electricity privatization. In 1995, the former director of safety at Scottish Nuclear, Richard Killick, claimed that Low morale, overworked operators, and the rush to reduce costs before privatization posed a threat of a significant reduction in safety [and that] privatization would erode safety culture (The Herald, 1993). Criticism of nuclear safety was also leveled against Nuclear Electric following an incident at the Wylfa Twin Magnox Power Stations in 1993 (Safety Management, 1995). In this incident, reactor operation was allowed to continue even though safety had clearly been compromised. However, Nuclear Electric denied that commercial considerations played any part in the decision to defer shutdown. 

Electrical safety program manager Given the unique issues and risks, it is valuable to designate an experienced individual to oversee electrical safety, and keep the company up to date on electrical code requirements and best practices. 

Electricity is one of the most cormnon power sources in otrr home and workplace envir-omnent. Electrical eqrripment, which uses electrical energy, forms a system which needs to be treated with respect. In other words, users and those in the vicinity of electricity ate required to be safety aware. Electrical equipment used in workplace envir-omnents and tasks needs to be considered for safety management. This includes such areas as the type of equipment used handling of equipment, and maintenance of systems in place to reduce the risks from electrical faults.

Electrical safety systems such as those detailed above will also assist in reducing the risk of fire caused by damage to installation cabling caused by vermin however, these systems should be supported by active management to control vermin for the risk of fire from these areas to be avoided or minimised. 

Documented systems to provide evidence of the testing, inspection, etc., together with a defect reporting system, should be considered to assist in managing electrical safety.
