1.3 Machine safety in the US

1.3 Machine safety in the US
An essential difference in the legal requirements regarding safety at work between
the US and Europe is the fact that in the US there is no legislation regarding ma-
chinery safety that is applicable in all of the states and that defines the responsibil-
ity of the manufacturers/supplier. On the other hand, there is a general requirement
that the employer must offer a safe workplace.
1.3.1

Minimum requirements of the OSHA

The Occupational Safety and Health Act (OSHA) from 1970 regulates the require-
ment that employers must offer a safe place of work. The core requirements of
OSHA are in Chapter 5 "Duties".
The requirements of the OSH Act are administered by the Occupational Safety and
Health Administration (also known as OSHA). OSHA employs regional inspectors
that check whether workplaces are in compliance with the valid regulations.
The regulations of OSHA, relevant for safety at work, 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 and use of the Standards is regulated in 29 CFR 1910.5 "Applica-
bility of standards". The concept is similar to that used in Europe. Standards for
specific products have priority over general Standards if the relevant aspects are
handled there. When the Standard is fulfilled, the employer can assume that he
has fulfilled the core requirements of the OSM Act regarding the aspects handled
by the Standards.
In conjunction with certain applications, OSHA specifies that all electrical equip-
ment and devices that are used to protect workers must be authorized by an
OSHA-certified, Nationally Recognized Testing Laboratory (NRTL) for the specific
application.
In addition to the OSHA regulations, it is important that the current standards from
organizations such as NFPA and ANSI are carefully observed as well as the exten-
sive product liability legislation that exists in the US. As a result of the product li-
ability legislation, it is in their own interests that manufacturing and operating com-
panies carefully maintain the applicable regulations and they are more or less
"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. Initially, self-insured compa-
nies do not have this requirement, but, in the case of an accident, they must prove
that they have applied generally recognized safety principles.
