Standard Practice for Safety Requirements in Metal Casting Operations: Sand Preparation, Molding, and Core Making; Melting and Pouring; and Cleaning and Finishing
ABSTRACT
This practice covers the safety requirements for applying the design, construction, and operation of machinery and equipment used in metal casting operations. These operations include sand preparation, molding, and core making; melting and pouring; and cleaning and finishing. This practice does not apply to die casting operations. This aim of this specification is to minimize the possibility of injury to operating and maintenance personnel while working on, or in the vicinity of, the specified equipment.
SCOPE
1.1 This practice covers the requirements of applying the design, construction, and operation of the machinery and equipment used in metal casting operations—sand preparation, molding and core making, melting and pouring, and cleaning and finishing. This practice does not apply to die casting operations.
1.2 Purpose—The requirements of this practice, including the training of supervisors and employees, are intended to minimize the possibility of injury to operating and maintenance personnel while working on, or in the vicinity of, the specified equipment. Compliance with this practice, in conjunction with OSHA regulations, provides a relatively safe environment, which is a fundamental requisite in helping to prevent occupational injuries.
1.3 Application:
1.3.1 New Installations—After the date of publication, all new installations within the scope of this specification shall be in conformance with its requirements. Any existing machine installation moved to a new plant or another location in the same plant is deemed a new installation when it is installed in the new location. However, an existing installed machine (former installation) that is moved for a short distance, for example, to provide additional aisle space, is not deemed to be a new installation.
1.3.2 Existing Installations—After the approval date of this practice, installations existing on, or before, this date shall be modified as necessary to be in conformance with all requirements of this practice. Where it is not practical to modify an existing facility in conformance with this practice, deficiencies shall be noted and plans for compliance shall be included in any future facility or equipment changes. Those facilities and equipment on order or in the process of construction on the date of publication of this practice shall be considered as an existing installation. This practice applies to existing equipment if it lacks the necessary employee protection (personal protective equipment or administrative controls).
1.4 The values stated in inch/pound units are to be regarded as the standard. The values in brackets are for information only.
1.5 The text of this practice references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

INTRODUCTION
This practice is part of a project started in 1972 under the sponsorship of the American Foundry
Society, Inc. Standard for Safety Requirements in Metal Casting Operations—Sand Preparation,
Molding, and Core Making; Melting and Pouring; and Cleaning and Finishing.
The metal casting industry shares safety considerations with many other industries requiring the
movementofheavyobjects,theuseoflargeovensandmeltfurnaces,andprocessingofhotmaterials.
In addition, there are safety considerations common to all industries.The present trend is towards the
development of industry-wide standards wherever the need for safety considerations exists. This
practice, therefore, is limited to safety considerations of special importance in the metal casting
industry operations in which general standards do not exist or are not considered adequate. This
practice is not intended to supersede or replace any applicable federal, state, or local governmental
safety regulations or requirements, but rather, it is intended to augment and support any such
requirements. Operating rules are not included in this practice unless they are vital to safety.
Compliancewiththispracticeshouldprovidearelativelysafeenvironment,whichisafundamental

The metal casting industry shares safety considerations with many other industries requiring the

In addition, there are safety considerations common to all industries. The present trend is towards the
