American National Standard

Approval of an American National Standard requires verification by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer.

Consensus is established when, in the judgment of the ANSI Board Of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution.

The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards.

The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute. Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on the title page of this standard.

CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard. Purchasers of American National Standards may receive current information on all standards by calling or writing the American National Standards Institute, 11 W. 42nd Street, New York, 10036, Phone: 212-642-4900, Fax: 212-398-0023.

FOREWORD

(This foreword is not part of American National Standard Z245.2-1997)

This American National Standard is applicable to the construction, reconstruction, modification, care, maintenance, operation, and use of stationary refuse compacting equipment. This American National Standard gives guidance on safety requirements for on-site waste and recycling equipment used in apartment, institutional, commercial, and industrial locations, including transfer stations and recycling facilities. This American National Standard shall not apply to compactors commonly referred to as domestic or household compactor appliances. This American National Standard specifies the characteristics of stationary compactors into a distinctly identifiable standard for ease in identification and the process of revision. This standard is a revision of ANSI Z245.2 –1992. Stationary compactors also have been addressed previously in ANSI Z245.1 (1978 and 1984 editions), Mobile Refuse Collection and Compaction Equipment, Safety Requirements. For mobile collecting and compacting equipment, refer to the ANSI Z245.1 standard.

Inquiries, requests for interpretation, and suggestions for the improvement of this standard should be directed to the Secretary, Accredited Standards Committee Z245, c/o Environmental Industry Associations, 4301 Connecticut Ave., NW, Suite 300, Washington, D.C. 20008.

This standard was processed and approved for submittal to ANSI by the Accredited Standards Committee Z245 on Equipment Technology and Operations for Wastes and Recyclable Materials. Committee approval of this standard does not necessarily imply that all members of the committee voted for its approval. At the time it approved this standard, the Z245 Committee had the following members:

Chris Voell, Chairman
John A. Legler, Vice-Chairman
Richard B. Curtis, Secretary

The Z245.2 Standard Development Subcommittee, which drafted this standard, had the following members:

Safety Requirements

1 Scope and purpose

1.1 Scope

This American National Standard is applicable to all persons engaged in the manufacture, modification, operation, cleaning, maintenance, service, or repair of stationary compacting equipment, and makes an attempt to distinguish between persons who may be the legal owner, lessor, lessee, or who are otherwise contracted with or hired to become involved with the equipment. This standard shall not apply to compactors intended for use in private homes, which are specifically excluded from the requirements of this standard.

1.2 Purpose

The purpose of this standard is to establish safety requirements with respect to the manufacture, reconstruction, modification, maintenance, service, operation, and installation (where applicable) of stationary compacting equipment.

1.3 Effective date

This standard revises the stationary compactor requirements found in ANSI Z245.2-1992. Provisions of that standard remain in effect. In order to enable manufacturers reasonable time to incorporate the provisions that are either new or are revisions of ANSI Z245.2-1992, the following guidelines have been selected by the Accredited Standards Committee Z245 as to effective dates:

-for all new stationary compacting equipment manufactured twelve (12) months after the approval date, the provisions of this revised standard, ANSI Z245.2-1996, shall apply, except that the provisions of 4.3, 4.4, 5.2, 6.1 and 6.2 of this American National Standard shall apply for all stationary compacting equipment, regardless of the date of manufacture, as of six months after the approval date of this standard;

-for all stationary compacting equipment manufactured from July 3, 1993 until 12 months after the approval date of this standard, the provisions of ANSI Z245.2 - 1992 shall apply;

-for all stationary compacting equipment manufactured from November 3, 1985 until July 2, 1993, the provisions of ANSI Z245.1 - 1984 shall apply;

1

-for all stationary compacting equipment manufactured from March 16, 1977 to November 2, 1985, the provisions of ANSI Z245.1-1975 shall apply;

Apartment/institutional stationary compactors are stationary compactors used in apartment complexes or institutions (see figure 1). Commercial/industrial stationary compactors are stationary compactors used in commercial businesses, industrial plants, or waste processing, disposal, transfer and recycling facilities, (see figures 2, 3 and 4).

3.44 stationary compactor-point of operation: The area of a stationary compactor where loading of material occurs.

3.45 sustained-manual-pressure control: A control that requires continuous pressure by the operator.

3.46 tailgate: The hinged gate or door(s) that closes the rear of the compactor container.

3.47 tilt-frame or roll-off equipment: The tilt-frame, tilt-frame support equipment, hoisting devices, tilt cylinders, and controls for operating the tilt-frame and hoisting devices for loading, dumping, and unloading containers or stationary compactors (see figure 5).

l) Keeping all surrounding walking areas and floors free from obstructions, and accumulations of waste matter, grease, oil, and water.

m) Maintaining records or employee reports of malfunctions required in clause 6.2(c);

n) Specifically inspecting safety interlocks, switches, and other protective devices to ensure that these devices are not disabled or bypassed, and not to permit the stationary

14

compactor to be operated unless these devices are fully functional. These inspections shall be in accordance with clause 6.1(e);

o) Ensuring that containers supplied are capable of withstanding the maximum forces generated by the compacting system.

e) Ensuring that the area of operation around container lifting systems and the container is clear of persons during all phases of the dumping operation prior to energizing the dumping system;

f) Ensuring that all persons are clear of the compactor point of operation before actuating any compaction cycle controls or container dumping controls and shall be ready to stop the compaction cycle or container dumping operation if necessary;

g) Ensuring that all persons are clear of the tailgate (on compactor-container combinations so equipped) before the tailgate is opened or shut. The operator shall warn all persons not to cross behind or under an open tailgate;

h) Using all compacting equipment in accordance with this standard and the manufacturer's instructions, including ensuring the proper position of all locks, doors, guards, etc;

i) Ensuring that no one disables or bypasses safety interlocks, switches, or other protective devices and that the stationary compactor is not operated unless these devices are fully functional;

j) Locking out (see clause 6.1(j)) the unit when inspecting malfunctions, jams, or other problems arising from daily operations; servicing; or performing maintenance (except maintenance testing). The affected employee shall identify the type and magnitude of the energy that the equipment uses, shall understand the hazards, and know the methods to control the energy.
