Scope and Applicability. This standard shall be
for the guidance of educators, operators, managers, and supervisors
in the safe setup and use of welding and cutting equipment, and the
safe performance of welding and cutting operations.
Beginning with the revision of 1983, the scope of ANSI Standard
Z49.1 has been refocused towards those safe practices for
performing welding, cutting, and allied processes, which are
generally within the implementation control of the welder or the
weld shop management. It is written in a manner suitable for
issuance to the welder and shop management to give practical
information to help them perform these functions safely. It also
contains information useful to educators, industrial hygienists,
engineers, and similar parties also responsible for safety and
health in welding. With this refocused scope, some provisions which
appeared in prior editions have been deleted. Those were provisions
which dealt more in matter of building design and construction,
facility pipelines, and electrical installations. Those provisions,
of course, are still important and necessary and must be followed.
They are not provisions usually under the immediate control of
welding and cutting operations.
Specific provisions are included for oxyfuel gas and arc welding
and cutting, resistance welding, electron beam welding, laser beam
cutting and welding, and brazing and soldering. However, the
requirements of this standard are generally applicable to the other
welding processes such as submerged arc welding and allied
processes shown in the American Welding Society Master Chart of
Welding and Allied Processes, included in Annex D.
Purpose. This standard is for the protection of
persons from injury and illness and the protection of property
(including equipment) from damage by fire and explosions arising
from welding, cutting, and allied processes.
