Workplace Air Monitoring – The Dangers of Entonox & How To Manage High-Risk Maternity Nurses

Workplace air monitoring has hit the headlines due to a hospital that has temporarily banned the use of popular maternity drug Entonox. 

Entonox, more commonly known as ‘gas & air’, is a gas used to help with pain management. But it seems that Hospitals are now realising that the risk to nurses who regularly help patients with Entonox, is very real.

Let’s highlight the risk

Exposure to gas and other airborne contaminants over a long time can cause significant health problems for employees. Entonox is a gas that needs treating in the same way. As a patient breathes in the gas, particles are also released into the air. This means that anyone working near someone being treated with Entonox, needs to be classed as high-risk. 

In the same way that other industries handle airborne contaminants, hospitals need to follow suit. And it is never too late to start. Once a risk has been identified, businesses should plan for, and begin implementing controls and measures to help safeguard employees. 

Hospital managers also need to consider how long-term management of gas & air will affect service users. Especially if this is a permanent ban. 

Employees regularly exposed to Entonox could present with the following symptoms:

  • Drowsy
  • Sleepy
  • Light-headed

However, these acute symptoms are just the tip of the iceberg. Long term exposure to Entonox can affect the body’s ability to absorb vitamin B12. Furthermore If our bodies aren’t able to absorb enough B12 we can suffer from long-term neurological, and blood disorders. You can read more about the risks of long-term exposure to Entonox here.

How to handle hazardous substances 

Entonox should be treated like any other occupational health hazard. And many industries where gas and other airborne contaminants are prevalent, often rely on workplace air monitoring. This compliance, which is regulated by the HSE, can cross over with other regulations such as Control of substances hazardous to health, and occupational health surveillance

What’s more, it’s especially important for high-risk employees. Which is exactly why taking steps to identify high-risk members of staff is essential when examining your legal responsibilities as an employer. 

Workplace air monitoring

As professionals, we recommend starting with a risk assessment for Entonox and other other gases. This will help you to identify where the risk exists, and who needs long-term monitoring. But it’s not just risk assessment that is important, we also need to think about:

  • Gathering data to help implement remedial actions effectively
  • Checking whether current control measures are effective, and putting some in place to ensure compliance
  • Ensure that workplace exposure limits are not exceeded
  • Identify health surveillance needs for at-risk employees 

Together, all those points make up the requirements for compliance with the HSE. And especially to help you safeguard employees whilst they are at work. Just the same was as you would any other workplace risk, workplace air monitoring for Entonox needs to be done as standard.
