Glossary of Terms

Bag-in/Bag-out (BIBO) is a high-containment method for replacing air filters, particularly HEPA filters in dust collection.

Capture velocity is the minimum hood-induced air velocity needed to capture airborne contaminants and pull them into the hood.

Control of Substances Hazardous to Health Regulations, or COSHH, is a law which requires employers to ensure the control of ‘substances that are hazardous to health’ within the workplace.

Cross contamination is the unintended transfer of contaminants from one process, product or area to another within a facility.

DSEAR, or Dangerous Substances and Explosive Atmospheres Regulations 2002 puts duties on employers and the self-employed to protect people from risks to their safety from fires, explosions and similar events in the workplace. This includes members of the public who may be put at risk by work activity.

Ductwork is the network of pipes, hoses, and connectors that transport captured dust, fumes, and airborne particles from machinery or workstations to a filtration unit or collection point.

Dust is fine dry solid particles generated by manufacturing processes. Industrial dust can be highly hazardous to employee health and product quality, posing respiratory, contamination, and explosion risks.

Dust collector is the system used in industrial settings to enhance air quality, by filtering and removing harmful dust particles from the air.

Dust control is the process of implementing systems, techniques, and measures to reduce, capture, or eliminate the generation and spread of airborne dust particles in industrial activities.

Dust extraction is the process of capturing, removing, and collecting airborne dust particles and fumes at the source during industrial processes.

Filtration is the process of separating solid airborne particles from an air stream to purify the air in industrial environments.

Front-End Engineering Design, also known as FEED, is a crucial engineering design phase that bridges the gap between conceptualisation and execution, and it’s used to scope, plan, and design work of a dust extraction project.

HEPA stands for High-Efficiency Particulate Air, and in dust extraction HEPA filters capture fine, hazardous, and respirable dust, trapping at least 99.97% of particulate.

High-vacuum refers to high pressure dust extraction units that ensure maximum suction of dust at source.

A hood is a primary component of a local exhaust ventilation (LEV) system, which captures airborne particles, dust or fumes directly at the source of generation.

Inhalable dust refers to dust that can enter the mouth and nose during breathing. These particles get trapped in the upper respiratory tract, affecting airways.

Local Exhaust Ventilation (LEV) systems capture and removes airborne contaminants like dust, fumes, and vapors at their source in a workplace

P601 refers to a British Occupational Hygiene Society (BOHS) proficiency qualification, which certifies an engineer is qualified to check that dust extraction equipment is working properly.

P602 is a professional qualification accredited by the British Occupational Hygiene Society (BOHS), which certifies an engineer is working at the professional standard for designing, installing, or evaluating Local Exhaust Ventilation (LEV) systems.

Particulate Matter (PM) is the term used for a mixture of solid particles and liquid droplets found in the air, ranging in size.

Pneumatic conveying is is process of transporting dry bulk materials such as powders and granules through enclosed pipelines using pressurised air.

Predictive maintenance uses real-time sensors to monitor key equipment, like dust collectors, to flag issues like overheating or excessive vibration.

Respirable dust refers to ultra-fine airborne particles that can penetrate deep into the lungs, bypassing natural defenses and potentially causing irreversible lung damage.

Trim extraction is an industrial process designed to remove waste materials, like paper or plastic trims, from production processes using high-powered fans and ductwork.

Waste handling systems capture, remove, and manage airborne particles generated during manufacturing, processing, or recycling.
