Breathing air quality testing ensures the safety of your employees

Breathing Air Quality Testing services from AEP will ensure your business is operating in line with its legal requirements.  This will help to ensure the safety of your employees in accordance with UK legislation and standards. 

Why is Breathing Air Quality Testing important for your business?  If relevant to your business, as an employer you are legally obligated to carry out breathing air quality tests.  The safety of your employees should be of paramount importance to your business with EN12021:2014 setting out the parameters you must adhere to.

How often should you test the air at your facility?  In the first instance, an assessment should be completed to thoroughly identify all areas of risk within your business operations.  Using this as a guide, air samples should be taken and then analysed to track levels of any contaminants.
