# Industrial Specification: Dust Containment System

## 1. Technical Definition
A safety and environmental control system designed to capture, contain, and prevent the escape of airborne pharmaceutical powder particles during blending operations.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.0 m/s face velocity at filter interface**. Failure boundary: **0.3 m/s face velocity at filter interface**, Mechanism: **Particle re-entrainment due to insufficient capture velocity; Stokes' law predicts particles &gt;5 μm diameter escape when drag force exceeds gravitational settling force at velocities below 0.3 m/s**.

### 2.1 Analytical Physics Model
Governed by the **Hansen Solubility Distance (HSP)**:

> **Primary Equation**: $R_a = \sqrt{4\Delta\delta_d^2 + \Delta\delta_p^2 + \Delta\delta_h^2}$  
> **Engineering Impact**: Predicts seal/gasket swelling when exposed to CIP chemicals.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| \delta_d | Dispersive | Engineering Constant |
| \delta_p | Polar | Engineering Constant |
| \delta_h | Hydrogen | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Filter media differential pressure exceeding 250 Pa | 8 | Filter media rupture and particulate breakthrough | Differential pressure monitoring with automatic shutdown at 200 Pa threshold |
| Static charge accumulation exceeding 10 kV on polymer ductwork | 8 | Electrostatic discharge igniting combustible dust cloud (MEC &lt;20 g/m³) | Conductive ductwork with resistance &lt;1×10⁶ Ω and grounding system with &lt;10 Ω impedance |

- **Caution**: 

### Q: What containment level (OEB) does this dust containment system achieve for pharmaceutical powder blending?
**A**: Our dust containment system is engineered to achieve OEB 4/5 containment levels, effectively preventing the escape of highly potent pharmaceutical powders during blending operations through negative pressure control and HEPA/ULPA filtration.

### Q: How does the pressure monitoring system enhance safety in chemical manufacturing environments?
**A**: The integrated pressure monitoring system continuously tracks differential pressure across the containment hood and filters, providing real-time alerts for any containment breaches or filter loading issues, ensuring consistent safety performance and regulatory compliance.

### Q: What maintenance is required for the HEPA/ULPA filter units in pharmaceutical dust containment?
**A**: HEPA/ULPA filters require periodic integrity testing (typically every 6-12 months) and replacement based on pressure drop indicators. Our system includes accessible filter housings and documentation support for validation protocols in regulated environments.
