The unit is not fitted with local exhaust ventilation.

Heated fresh air was supplied in living spaces and exhaust ventilation is provided at necessary locations.

In March 2005, local residents protested construction plans primarily due to the expected air pollution from exhaust ventilation stacks.

Researchers have been evaluating the effectiveness of the different local exhaust ventilation systems in ventilated nail tables.

The exhaust ventilation system was superseded by forced ventilation.

The standard for vapor degreasers specifically recommends against local exhaust ventilation because of its potential role in generating emissions to the environment.

When there are strong pollutant sources, local exhaust ventilation may be appropriate to exhaust contaminated air directly from the building.

Local exhaust ventilation, often called dust and/or fume extraction, can help clean the air, before people breathe in these harmful substances.

The two-speed exhaust ventilation hood easily converts to a non-vented (recirculating) model, too.

Indeed, early industrial hygienists maintained that source reduction was not a practical approach, nor even theoretically superior to local exhaust ventilation, from a prevention standpoint.

Local exhaust ventilation is particularly recommended to remove pollutants that accumulate in specific areas such as rest rooms, copy rooms, and printing facilities.

Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area.

Local exhaust ventilation addresses the issue of avoiding the contamination of indoor air by specific high-emission sources by capturing airborne contaminants before they are spread into the environment.

In some cases a micro-heat pump is used to extract additional heat from the exhaust ventilation air, using it to heat either the incoming air or the hot water storage tank.

For example, the introduction of mechanical exhaust ventilation may transfer the risk from the same hazard (fumes) from the employee to the general public as the fumes are pumped outside the workplace.

Dispersion or dilution of dust produced depends on the extent of confinement of the sources and the work area, as well as the presence and effectiveness of exhaust ventilation.

A year later, an independent expert stated that Nike had, "substituted less harmful chemicals in its production, installed local exhaust ventilation systems, and trained key personnel on occupational health and safety issues."

Ventilation engineers advise on the design and testing of general and local exhaust ventilation to control exposure to airborne hazards to health such as mists, dusts, gases, vapours and fumes.

When writing down your results, keep it simple, for example 'Tripping over rubbish: bins provided, staff instructed, weekly housekeeping checks', or 'Fume from welding: local exhaust ventilation used and regularly checked'.

A few substitutes for methylene chloride are briefly described in the compliance guides that accompany the standard, but these guides focus on local exhaust ventilation and work practices as the best ways to lower exposure.

In the sealant operation, the mixing of the sealant had occurred without local exhaust ventilation, although the manual and automatic application work area was equipped with local exhaust ventilation.

Rather than utilize the traditional control approaches delineated in environmental and occupational health regulation, such as pollution control equipment or local exhaust ventilation that facilitate the continued use of hazardous chemicals, these companies chose a source reduction approach.

Local exhaust ventilation, the process of "changing" or replacing air in any space to provide high indoor air quality (i.e. to control temperature, replenish oxygen, or remove moisture, odors, smoke, heat, dust, airborne bacteria, and carbon dioxide)
