Electrical safety standards Electrical safety standards Electrical safety is a system of organizational measures and technical means to prevent harmful and dangerous effects on workers from electric current, electric arc, electromagnetic field and static electricity. The electrical safety develops with the technical progress. In 1989 OSHA promulgated a much-needed regulation in the General Industry Regulations. Several standards are defined for control of hazardous energy, or lockout/tagout. In 1995 OSHA was successful in promulgation of regulations for utility. In 1994 were established Electrical Safety Foundation International non-profit organization dedicated exclusively to promoting electrical safety at home and in the workplace. Standards are compared with
Convergence of measures Convergence of measures In mathematics, more specifically measure theory, there are various notions of the convergence of measures. For an intuitive general sense of what is meant by "convergence in measure", consider a sequence of measures μ on a space, sharing a common collection of measurable sets. Such a sequence might represent an attempt to construct 'better and better' approximations to a desired measure μ that is difficult to obtain directly. The meaning of 'better and better' is subject to all the usual caveats for taking limits; for any error tolerance ε > 0 we require there be "N" sufficiently
