Ventilation Hazard Icon

Ventilation

Maintaining good air quality

When working in confined or enclosed spaces, such as basements, tunnels, pits and shafts, poor air quality can put the health of your workers at significant risk. Contaminated air can have an adverse effect on both your immediate and long-term health, and in the most severe cases, can be fatal.

Effective Ventilation

Let an RVT consultant handle the complex calculations for you!

Challenge

Every project is different and poses its own interesting challenges. Ideally you will be looking to dilute the hazard by forcing clean air into the work space or using positive pressure ventilation to purge the hazard, however there are many scenarios in which you might also consider negative pressure extraction.

Risk

If you do not have an effective ventilation solution it can have a significant impact on workers' health. The effect of poor air quality varies substantially depending on the exposure time, type of contaminant and concentration of contaminant. 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.

Solution

Calculating ventilation requirements can be tricky and there are a number of things to consider;

  • Identify the hazards; dust, fumes, heat or gases?
  • Will you be using any machinery or equipment?
  • How many people will be working in the space?
  • How long will they be in there?
  • What size is the work area?
  • Does access pose a problem?
  • How far away is the fresh air source?
  • Do we need to apply positive or negative pressure?
  • How many air changes are needed?
  • What airflow and air pressure is required?

We recommend speaking to a fully trained RVT consultant to help you install a fully effective, reliable and robust Ventex ventilation solution on site.
