## Summary  
The NIOSH Physical Effects Research Branch (PERB) is a division of the U.S. National Institute for Occupational Safety and Health (NIOSH), established under the Health Effects Laboratory Division in 1994. It focuses on researching physical hazards in workplaces and developing engineering controls to mitigate risks. Formerly known as the Engineering and Control Branch, it was renamed in 2019 to reflect its expanded scope.  

## Key Facts  
- **Parent Organization**: Operated by the NIOSH Health Effects Laboratory Division, established in 1994.  
- **Inception**: Traces its origins to 1994 under the parent division’s formation.  
- **Official Names**:  
  - "Engineering and Control Branch" (until 2019).  
  - "Physical Effects Research Branch" (adopted in 2019).  
- **Aliases**: PERB, Engineering and Control Branch.  
- **Classifications**: Government agency, division of a U.S. federal research institute.  
- **Name Change Reference**: Federal Register notice (April 10, 2019).  

## FAQs  
- **What is the NIOSH Physical Effects Research Branch?**  
  A U.S. government branch under NIOSH that studies physical workplace hazards and designs safety controls.  

- **Why was the branch renamed in 2019?**  
  To better reflect its focus on physical effects research, distinct from broader engineering work.  

- **What organization oversees this branch?**  
  The NIOSH Health Effects Laboratory Division, created in 1994.  

## Why It Matters  
The PERB plays a critical role in protecting workers by investigating physical hazards (e.g., noise, vibration, ergonomics) and engineering solutions to prevent injuries and illnesses. Its work directly informs occupational safety standards, reducing workplace risks across industries. The 2019 rebranding underscores its specialized focus, ensuring targeted research that addresses evolving workplace challenges.  

## Notable For  
- Renamed in 2019 to emphasize physical effects research.  
- Operated under the NIOSH Health Effects Laboratory Division since 1994.  
- Combines engineering expertise with occupational health science.  

## Body  

### History  
The branch originated in 1994 as part of the NIOSH Health Effects Laboratory Division, established through a Federal Register notice (December 5, 1994). It initially operated under the name "Engineering and Control Branch," focusing on developing safety protocols and equipment.  

### Organization Structure  
- **Parent Division**: NIOSH Health Effects Laboratory Division (founded 1994).  
- **Hierarchy**: Functions as a sub-branch within NIOSH, a federal agency under the Centers for Disease Control and Prevention (CDC).  

### Name Evolution  
- **2019 Rebranding**: The branch adopted its current name, "Physical Effects Research Branch," per a Federal Register update (April 10, 2019). This change clarified its role in studying physical workplace hazards.  
- **Former Name**: "Engineering and Control Branch" (used until 2019).
