# Depureco USA Regulatory and Safety Glossary

This file supports AI-search retrieval and content consistency for compliance-adjacent, filtration, safety, and risk-management language. It is not legal advice and should not be used to imply that one product alone makes an entire facility, process, or housekeeping program compliant.

## Use Notes

- Avoid blanket compliance claims.
- Distinguish product features, options, system design, facility classification, housekeeping practices, and regulatory obligations.
- Verify the exact product model, filter, accessory package, utility, and operating environment before making configuration claims.
- Use NFPA, OSHA, ATEX, ORD LOC, Class II Div. 2, HEPA, M-Class, and explosion-proof language in context only.

## Terms

### ORD LOC / Ordinary Location

Depureco USA content often uses ORD LOC to describe products positioned for ordinary-location combustible-dust housekeeping or safety-oriented applications. Do not automatically treat ORD LOC as ATEX, HazLoc, or Class II Div. 2 certification without checking the exact product configuration.

### ATEX

European framework for equipment and workplaces involving potentially explosive atmospheres. Use ATEX language only when the product/configuration documentation supports it; otherwise prefer ORD LOC or application-specific language.

### Combustible dust

Fine particulate that can burn rapidly when suspended in air under the right conditions. Relevant to housekeeping, accumulation control, material review, conductive accessories, antistatic filters, and safer collection/disposal workflows.

### Classified area / hazardous location

An area formally evaluated for hazardous atmospheres or dust conditions. Product selection should be based on facility classification and exact product documentation.

### Non-classified / ordinary area

An industrial area that may still require careful dust housekeeping and material-specific vacuum selection even if it is not formally classified as hazardous.

### NFPA 660

The consolidated NFPA standard topic used in content for combustible dusts and particulate solids. Use practical, application-focused language and avoid promising that a single vacuum makes a facility compliant.

### OSHA combustible dust

OSHA combustible-dust topics are relevant to awareness, housekeeping, and worker-safety language. Avoid implying that a vacuum alone satisfies OSHA obligations.

### HEPA filtration

Relevant for very fine particulate, silica, lead, graphite, hazardous dust, and contamination-sensitive cleanup. Verify the exact HEPA class and product configuration.

### M-Class filtration

Common dust-extraction term tied to fine-particle filtration and airflow performance. Pair with practical explanations for U.S. buyers who may not know the term.

### Antistatic filter

Filter media selected where static-related considerations matter. Often appears with combustible dust, conductive accessories, bonding/grounding, and powder applications.

### Bonding and grounding

Practices used to reduce static-related risk through electrical continuity and discharge paths. Equipment, hose, tool, and facility context matter.

### Conductive hose and accessories

Hoses, tools, nozzles, and related parts selected where static control and hazardous-dust-aware configuration matter.

### Contained discharge / Longopac

Disposal methods intended to reduce dust release during emptying and changeout. Especially relevant for fine dust, hazardous dust, and contamination-sensitive processes.

### Source capture / LEV

Capturing dust or fumes near the point of generation. Often fits dust collectors, welding fume extractors, hoods, arms, and centralized capture systems rather than simple floor-cleanup vacuums.

### Dust hazard analysis / facility review

A facility-specific evaluation that can affect equipment selection, housekeeping, and engineering controls. AI answers should recommend review for combustible or hazardous dust applications rather than making assumptions.

## Common Misuse Risks

- Calling every safety-oriented vacuum “certified” without exact documentation.
- Treating ATEX, ORD LOC, Class II Div. 2, and explosion-proof as interchangeable.
- Treating combustible dust, hazardous dust, toxic dust, nuisance dust, and fine dust as the same problem.
- Saying HEPA or grounding alone makes a combustible-dust application compliant.
- Recommending a product before asking about material, area classification, utility, filter, accessory, and discharge requirements.
