    BRIEF

    Policy Summary

    The Lawrence Berkeley National Laboratory (Berkeley Lab) Ventilation Program protects workers and the environment by:

    • Reducing airborne concentrations of contaminants.
    • Ensuring hoods, HEPA filters, and exhaust ventilation systems meet requirements.
    • Establishing minimum performance requirements for hoods, HEPA filters, and exhaust ventilation systems.
    • Performing periodic surveillance of hoods, HEPA filters, and exhaust ventilation systems.

    Who Should Read This Policy

    Berkeley Lab employees, visitors, affiliates, and subcontractors who work with hazardous substances

    POLICY

    A. Purpose

    The Ventilation Program at Lawrence Berkeley National Laboratory (Berkeley Lab) protects workers and the environment by:

    • Reducing airborne concentrations of contaminants.
    • Ensuring hoods, HEPA filters, and exhaust ventilation systems meet requirements.
    • Establishing minimum performance requirements for hoods, HEPA filters, and exhaust ventilation systems.
    • Performing periodic surveillance of hoods, HEPA filters, and exhaust ventilation systems.

    The Ventilation Program includes laboratory fume hoods, inert and negative-pressure glove boxes, biological safety cabinets, HEPA-filtered vacuum cleaners, in-place HEPA filters used for contaminant control, and other local exhaust ventilation systems, such as extractor arms, exhausted enclosures, ventilated tanks, back-draft benches, and canopy hoods.

    B. Persons Affected

    Berkeley Lab employees, visitors, affiliates, and subcontractors who work with hazardous substances

    C. Exceptions

    None

    D. Policy Statement

    The Environment, Health and Safety (EHS) Division must be notified of the purchase of hoods, glove boxes, filtering equipment, emissions-collection equipment, and other relevant ventilation items. EHS may review the use of such ventilation systems with the requestor. EHS must be consulted to determine applicable design, construction, and performance standards for new ventilation systems used for contamination control. Responsibility to ensure the systems meet applicable requirements resides with the Project Manager for Facilities Division projects and with the activity line manager for all other projects.

    1. New and relocated ventilation systems may not be used for contamination control until installation and performance has been evaluated and "tagged" by EHS and verified to meet application standards.
    2. Line management must ensure that ventilation systems that do not meet performance standards (i.e., are deficient) are repaired, and are used within safety limits (if allowed) until repaired.
    3. Performance of ventilation systems, including HEPA-filtered units, must be periodically evaluated.

    E. Roles and Responsibilities

    See ES&H Manual Chapter 4 for roles and responsibilities related to the execution of this policy's implementation.

    Role

    Responsibility

    Facilities Division

    • Ensures that newly installed or refurbished ventilation systems are designed, installed, commissioned, and function-tested in accordance with applicable codes and guidance provided by the EHS Division.
    • Maintains a proactive preventive-maintenance program to ensure that ventilation systems are in proper operating condition in accordance with applicable codes and guidance that it has provided.

    Industrial Hygiene Subject Matter Expert (SME)

    • Ensures that performance standards are identified for ventilation systems and that periodic surveillance is performed.
    • Ensures the development, approval, revision, and administration of this policy and its implementing documents.

    Line Managers

    Ensure that persons within their areas of responsibility comply with this policy and its implementing documents.

    Supervisors and Work Leads

    Ensure that persons within their areas of responsibility comply with this policy and its implementing documents and have completed any required training prior to beginning work.

    Ventilation System Users

    Follow all guidance provided in training and this policy and its implementing documents.

    F. Definitions/Acronyms

    See ES&H Manual Chapter 4 for technical terms related to the details of this policy and its implementation.

    G. Recordkeeping Requirements

    • The results of all calibration, certification, and other checks are recorded in the Berkeley Lab Ventilation Database and maintained by the EHS Division.
    • Ventilation systems are marked with stickers that indicate when the last surveillance check was performed.
