Ventilation Hazard Icon


Specialised exhaust fume control equipment and filters.

Poor air quality puts the health of your workers at risk and can be a particular problem in confined areas. Low levels of oxygen or the presence of harmful fumes in the air can have an adverse effect on both your immediate and long-term health, and in the most severe cases, can be fatal.

Capture, Contain, Control.

A proven methodology, devised by the RVT Group, to ensure effective control of all on-site health hazards.


In confined spaces such as tunnels, pits, shafts and basements, maintaining a constant flow of fresh air can be challenging. You need to calculate the size of the area to establish how many air changes are required per hour. You also need to know how far away the fresh air source is so that you can calculate how much pressure is required to force fresh air along the ducting. You also need to identify what substances are contaminating the air, for example; carbon monoxide, diesel fumes, methane, nitrogen dioxide, nitrous oxide, hydrogen sulphide etc.; as this may drastically change your ventilation strategy.


The effect of poor air quality varies substantially depending on the exposure time, type of contaminate and concentration of contaminate. Workers could therefore experience anything from dizziness, fatigue and breathing problems, to lung disease and heart disease. In the most severe instances, poor air quality can result in death.


RVT believe that effective ventilation can be managed in three easy steps;

  1. Capture the hazard - Extract contaminated air out of the work space.
  2. Contain the hazard - Ensure that the work area remains under pressure as this will help to control air movement (either positive or negative pressure depending on the application).
  3. Control the hazard - Force in clean air to dilute the hazard.
