We can all learn together, right? For now, be aware of the different terms systems and programs, and know we plan on focusing on that issue in the next article in this series. ANSI Z10 was revised in You can read more about it here , including keeping up with the various comment periods, extensions, and ultimately its final release.

Elimination of the hazard when possible is always the best approach. Method No. However, notice it is last in the hierarchy. There are four other risk-control methods between elimination and PPE.

When published, it will provide guidance for integrating more safety elements into the design of electric-power systems.

The techniques in this Practice are intended to supplement the minimum requirements of installation codes and equipment standards. The new standard will provide a wealth of information. Here is a sample of topics that it covers. The National Electrical Code NEC defines the minimum requirements for properly selecting overcurrent protective devices. Make the wrong selection and the arc flash hazard could become more severe even though you complied with the NEC.

Maintenance and operation also need to be considered. During the design stage, an initial risk assessment should be conducted to identify important safety details, such as where energy isolation devices are needed.

The new standard discusses various design options in great detail. Distance is another factor when it comes to arc flash safety.

The closer a person is to an arc flash, the greater the incident-energy exposure. This minimizes the extent of an outage and typically requires a protective device closer to the source to operate more slowly than devices closer to the load in response to abnormal currents. There are many methods that can be used to provide the best of both worlds. Arc flash energy-reduction methods, such as maintenance switches and devices with multiple setting groups, can be used to temporarily enable high-speed fault clearing when an arc flash hazard is present.

Differential protection and zone-selective interlocking may also be used. The introduction of risk assessment and risk control in the edition of NFPA 70E is a game-changer. IEEE will go a long way toward helping the electrical designer meet these new requirements by controlling risk through safer design.


OSHAS 18001:2007/ANSI-AIHA Z10/ISO45001/SHARP – Occupational Health & Safety

Performance Evaluation Improvement The goal of this structure, which parallels the ten- section format of ISO , is to make certification to easier for users of Z10 to achieve. Sections 5 through 10 of both standards cover basic elements and requirements. Traditional health and safety programs concentrate most of their energy and activity on the requirements in section 8 Operation. That is where the heavy lifting of eliminating hazards, reducing risks, and ensuring regulatory compliance is typically done. The key to success for health and safety management systems is to strengthen elements covered in other sections, which guide and reinforce improvements in operation and help integrate health and safety with other business processes.

OSH Management (Z10)

OHSAS vs. VPP: Does it really matter? Safety management systems have been around for a number of years, and they come in several different variations. Management systems in general are what they sound like: a framework for systematically managing an aspect of an organization. Effectiveness of a management system is measured in its ability to provide continual improvement in the selected aspect. The measurements that organizations use to define continual improvement plays a role in the selection of the framework.
