Minimum Requirements Of The Osha; Nrtl Listing - Siemens Sinamics S110 Function Manual

8.1.3.1

Minimum requirements of the OSHA

The Occupational Safety and Health Act (OSHA) from 1970 regulates the requirement that
employers must offer a safe place of work. The core requirements of OSHA are specified in
Section 5 "Duties".
The requirements of the OSH Act are managed by the Occupational Safety and Health
Administration (also known as OSHA). OSHA employs regional inspectors who check
whether or not workplaces comply with the applicable regulations.
The OSHA regulations are described in OSHA 29 CFR 1910.xxx ("OSHA Regulations (29
CFR) PART 1910 Occupational Safety and Health"). (CFR: Code of Federal Regulations.)

The application of standards is regulated in 29 CFR 1910.5 "Applicability of standards". The
concept is similar to that used in Europe. Product-specific standards have priority over
general standards insofar as they cover the relevant aspects. Once the standards are
fulfilled, employers can assume that they have fulfilled the core requirements of the OSH Act
with respect to the aspects covered by the standards.
In conjunction with certain applications, OSHA requires that all electrical equipment and
devices that are used to protect workers be authorized by an OSHA-certified, Nationally
Recognized Testing Laboratory (NRTL) for the specific application.
In addition to the OSHA regulations, the current standards defined by organizations such as
NFPA and ANSI must be carefully observed and the extensive product liability legislation
that exists in the US taken into account. Due to the product liability legislation, it is in the
interests of manufacturing and operating companies that they carefully maintain the
applicable regulations and are "forced" to fulfill the requirement to use state-of-the-art
technology.
Third-party insurance companies generally demand that their customers fulfill the applicable
standards of the standards organizations. Self-insured companies are not initially subject to
this requirement but, in the event of an accident, they must provide verification that they
have applied generally-recognized safety principles.
8.1.3.2

NRTL listing

To protect employees, all electrical equipment used in the USA must be certified for the
planned application by a "Nationally Recognized Testing Laboratory" (NRTL) certified by the
OSHA. NRTLs are authorized to certify equipment and material by means of listing, labeling,
or similar. Domestic standards (e.g. NFPA 79) and international standards (e.g. IEC/EN
61508 for E/E/PES systems) are the basis for testing.
