As a responsible manufacturer, Dalair Limited is committed to best practice in all matters relating to the health, safety and welfare of its employees and those who may be affected by our business activities.

Our aim is to develop a culture whereby the achievement of health and safety objectives will be regarded as an integral part of our business.
