controlled. All contractors and subcontractors using chemicals on the site are responsible for managing

the chemicals from the time the chemical enters the site or is issued to the user until it is dispositioned as

reusable/recyclable, empty, or waste.

During the work-planning phase of a new job or project, all chemicals that will be used for the job or

project are identified and assessed for potential health and physical hazards. Hazard analysis

documentation or the equivalent operating manuals or procedures that govern processes and equipment

are required for all work with known and suspected human carcinogens, chemicals of high acute or high

chronic toxicity, known human reproductive toxins, and explosives. Any product chemical brought

onsite by visitors or subcontractors must have an MSDS and must be reported to the host or the facility

manager.

2.2 Acquisition

A centralized Chemical Stores subcontractor manages the procurement of all chemicals and laboratory

supplies and onsite transportation of products to chemical users at LANL. Chemicals obtained through a

purchase request are delivered to the Chemical Stores location, where ES&H Division personnel apply

bar-codes and enter data into the ACIS. Gas cylinders and bulk gases are received and delivered by the

Compressed Gas Processing Center in the Business Operations Division. A chemical purchase report is

provided to ES&H division. This is the primary method to determine that bulk tanks have been refilled.

2.3 Inventory and Tracking

The ACIS is used to track chemicals onsite and to maintain inventories. This system also provides the

necessary data and reports to prepare New Mexico Environment Department submittals and support for

compliance, medical surveillance, exposure monitoring, facility authorization, and safe management. In

addition, the ACIS tracks SARA Title III reporting of onsite hazardous materials and toxic release

inventories. Each record contains a unique bar-code; the chemical content, including name, Chemical

Abstract Service (CAS) number, amount, manufacturer, and catalog number; location of the chemical

(technical area, building, room, and location comments); and its state (solid, liquid, gas), special

temperature requirements, and ownership (group, owner's name, and owner's Z number). LANL

subscribes to several MSDS services. Additionally manufacturers' MSDSs are scanned into an MSDS

web site. Future enhancements of ACIS will connect an ACIS bar-code directly to an MSDS. Chemical

owners can access a generic MSDS for a chemical name or CAS number, as well as all MSDSs for onsite

manufacturers.

Viewing and updating ACIS data requires the proper ACIS authority. Chemical owners at LANL have

full viewing and updating authority only over chemical containers in their ownership. To gain authority

over all the containers in a group (ACGRP), the group leader must grant ACGRP. Access to an entire

division's containers requires an e-mail from that division office, requesting that this level of authority be

granted. The ES&H Division has provided a web interface that allows access to ACIS data for authorized

users. Owners can use this web site in a number of ways. They can add a container, update the location of

a container if it has been moved, mark a container as surplus for internal recycling, mark containers as

disposed when the contents have been consumed, perform an annual inventory, accept a chemical

transferred to their ownership, and transfer a chemical to another's ownership.

Chemicals in secondary containers are not tracked except when the building inventory has reached 80

percent of the threshold value for the chemicals listed in 40 CFR 68.130, "Chemical Accident

sent to the management chain when a chemical has exceeded the 80 percent threshold in a building.
