Hazardous Materials Management Program

Sandia is a multiprogram laboratory operated by Sandia Corporation, a Lockheed Martin Company,for the United States Department of Energy’s National Nuclear Security Administration under contract DE-AC04-94AL85000.


Snl ca hazardous material reduction drivers
SNL/CA Hazardous Material Reduction Drivers

  • 2006 SNL/CA EMS Goal - 5% reduction by container

  • 2006 reduce NFPA Health 3 and 4 materials in the 5 EPHA target areas with the objective of eliminating at least 2 out of the proposed 5 areas.

  • New DOE Requirements

    • DOE O 151.1C Emergency Management - Hazards Survey focus on NFPA Health 3 & 4 Materials (11/2005)

    • DOE requirement on the Management of Unneeded Materials and Chemicals (UMC) (12/2005)

  • Existing Sandia Requirements

    • ES&H Manual

      • Section 4P - Housekeeping

      • Chapter 5 - Fire Protection

      • Section 6D/6E - Haz Comm/Lab Standard - Chemical Hygiene Plan

      • Section 6U - Chemical Barcoding and Inventory

    • Fire Protection

      • International Fire Code Implementation


Inventory reduction campaign emphasis
Inventory Reduction Campaign Emphasis

  • Hazardous Materials (> 10 years old)

    • 23% of the SNL/CA site inventory is > 10 years old

    • 24% of the NFPA Health 3 & 4 inventory is > 10 years old

  • Hazardous Materials (> 5 years old)

    • 45% of the SNL/CA site inventory is > 5 years old

    • 47% of the NFPA Health 3 & 4 inventory is > 5 years old


Chemical information system cis
Chemical Information System (CIS)

  • Integrated Chemical Inventory and Material Safety Data Sheet (MSDS) Container Tracking System

    • Current Inventory and Historical Data Storage

      • ~120,000 Tracked Chemical Containers at SNL/NM

      • ~35,000 Tracked Chemical Containers at SNL/CA

      • ~ 25,000 Unique Chemicals/Chemical Products

      • 1500 Chemical Storage Locations (building/room)

      • Dynamic Inventory - Daily Inputs (new entries and disposals)

  • MSDS library of over 85,000 via the SNL Internet

    • Available for Routine or Emergencies On-site and Off-site 24 x 7

    • Dynamic Library - Daily Inputs (new entries and updates)

  • Basis for federal/state reporting (i.e. Emergency Planning Community Right-To-Know Act)


  • Key cis business rules functions
    Key CIS Business Rules/Functions

    • Conservative Inventory Tracking Rule

      • All Chemical Containers are Considered Full While in the Inventory

    • Inventory Data is Linked an MSDS

      • CAS used in MSDSs forIingredients

      • CAS Unique Identifier for Chemical Structure

      • Identifies Basic Physical State but not Form

    • Off-line CIS Data Available Quarterly to EOC

      • Used when CIS is Unavailable (i.e., network/power outage)


    Quality assurance
    Quality Assurance

    • Annual Chemical Inventory Reconciliation

      • Reconcile differences between physical inventory and database information

      • Wall-to-wall walk down is conducted (May – August)

      • Process ensures that CIS database is in line with physical inventory

      • Results forwarded to lab owners and ES&H professionals for review


    Inventory reduction data challenges
    Inventory Reduction Data Challenges

    • Baseline Recalculation

      • Organization Ownership Changes

      • New Locations/Organizations

    • Inventory is “Lost” and “Found” each year during the Summer Reconciliation

    • Data Presentation

    • Container Count vs. Received Container Contents Weight

    • Very Small or Very Large Containers Allow for Gaming Reduction Results


    Inventory reduction line challenges
    Inventory Reduction Line Challenges

    • Academic/Organizational Freedom

      • Ownership/Responsibility

    • Product Chemical Safety

      • Peroxidizable, autopolymerizable

      • i.e., Picric Acid

      • Inventory is “Lost” and “Found” Each Year During the Summer Reconciliation

    • Product Quality

      • Manufacturer Expiration Dates

      • General Shelf Life

    • Product Disposal Costs

      • Line labor

      • Waste Management Chargeback


    Inventory reduction conclusions
    Inventory Reduction - Conclusions

    • Hazardous Material Safety
