      Conservation or restoration laboratory of a heritage custodian.
      
      **DEFINITION**:
      
      A ConservationLab is a specialized facility where conservation professionals
      perform preventive conservation, remedial treatment, and restoration of
      heritage materials. These labs require specialized equipment, climate control,
      and safety features for working with collection objects.
      
      **GETTY AAT ALIGNMENT**:
      
      `aat:300263557` (conservation laboratories) - "Laboratories where objects,
      documents, works of art, or specimens are examined, tested, and treated
      for preservation or restoration."
      
      **DISTINCTION FROM OTHER AUXILIARY PLACE TYPES**:
      
      | Type | Primary Function | Staff |
      |------|------------------|-------|
      | **ConservationLab** | Object treatment/preservation | Conservators |
      | ResearchCenter | Academic research | Researchers |
      | Storage | Collection housing | Collections staff |
      | AdministrativeOffice | Back-office operations | Admin staff |
      
      **TYPICAL CHARACTERISTICS**:
      
      - **Specialized equipment**: Microscopes, fume hoods, treatment tables
      - **Climate control**: Precise temperature/humidity for materials
      - **Safety features**: Ventilation, chemical storage, fire suppression
      - **Restricted access**: Conservation staff only (hazardous materials)
      - **Documentation systems**: Treatment records, imaging equipment
      
      **CONSERVATION SPECIALIZATIONS**:
      
      Labs may specialize in specific material types:
      - Paper/book conservation (archives, libraries)
      - Paintings conservation (museums, galleries)
      - Textile conservation (costume, ethnographic collections)
      - Objects conservation (3D artifacts, sculpture)
      - Photographic conservation (film, prints, negatives)
      - Digital preservation (born-digital materials)
