Xylene Medical Uses, Hazards, and Exposure Limits

/in , , , /by

In this post, we’ll focus on the medical and dental applications of xylene. We’ll explore the exposure risks and advise on how you can best manage them to protect your staff from short- and long-term health effects.

What is Xylene?

Xylene is a colourless liquid, a volatile organic hydrocarbon with a distinctive sweet smell. It might also be referred to as dimethyl benzene, methyl toluene, and xylol. Xylene is used in many industries, and it carries certain exposure risks.

Xylene Medical and Dental Uses

Xylene has major applications in histology, or microanatomy. Technicians use xylene to process and stain tissue samples, making them transparent so they can better determine the presence of diseases. Histopathology technicians may also use xylene to clean slides of stains, to make them more visible under microscopes.

Xylene is also widely used as a cleaner in medical and dental settings, often as part of a disinfectant solution. Finally, certain chemicals containing xylene can have specialist medical uses. For example, P-xylene-2-sulfonic acid can be used as a reagent to determine cholesterol levels in serum.

Xylene Hazards and Exposure Risks

One major hazard of xylene is that it’s highly flammable at room temperature. This alone means staff should take great care when storing, handling, or transporting xylene. Also, xylene is not soluble in water, which can make containment and cleaning more difficult in the event of a spillage.

Xylene is highly irritant to the skin, and it can cause damage to the cornea if it comes into contact with the eyes. Yet the greatest risks come from inhaling xylene.

Effects of Short-Term Exposure to Xylene

In the short term, this can lead to dizziness, nausea, fainting, headaches, vomiting, visual impairments, and even heart arrhythmias.

Effects of Long-Term Exposure to Xylene

When xylene enters the bloodstream, it slows down the central nervous system. As a result, long-term exposure can result in major organ damage.

Xylene Workplace Exposure Limits

COSHH legislation means that staff must only be exposed to a certain amount of a hazardous substance in a specified period of time. This is known as the time weighted average (TWA).

Xylene has a TWA of 50 ppm, or 220 mg/m3 in 8 hours. The short-term exposure limit (STEL) is 100 ppm, or 441 mg/m3 in 15 minutes.

How to Manage the Risks of Xylene Exposure

  • Store xylene in tightly closed containers in a cool, dry, segregated, and well-ventilated area, away from any possible source of ignition. Eye wash facilities and emergency cleaning facilities must also be available.
  • Xylene must only be used in well-ventilated areas.
  • Any staff handling xylene should wear appropriate PPE. This includes safety goggles, protective gloves, and overalls to minimise all forms of skin contact. If there is insufficient ventilation in the area, respiratory protection will also be necessary.
  • In the event of a spillage, any contaminated clothing must be removed and washed before re-use. Cleaners should use a dedicated chemical spill kit to prevent the xylene from spreading and entering drains or water courses.
  • In the event of skin contact, wash the area thoroughly with soap and water, and seek immediate medical attention if irritation develops or persists.
  • In the event of eye contact, rinse eyes continuously for at least 15 minutes, removing any contact lenses before rinsing.

How Many Dentists are Training and Qualifying in the UK?

/in , /by

The UK is facing a shortage of dentists. According to one report, there were 21,544 dentists in the UK at the end of January 2022, compared to 23,733 at the end of 2020.

The British Dental Association (BDA) found that 75% intend to reduce, or further reduce, their NHS commitment over the next 12 months when they surveyed dentists.

NHS Dentist Shortage News

Indeed, many stories of “dental deserts” have made the news in the early months of 2023:

For more, you can read our full guide to the NHS dentist shortage. This guide discusses some of the underlying causes of this shortage, and some of the initiatives that may address the shortage.

In this post we’ll provide an essential update on the situation through taking a closer look at the current figures for the number of dentists currently training and qualifying in the UK.

How Many Dentists are Operating in the UK?

The most up-to-date NHS dental statistics for England are from 25 August 2022. These figures reveal that 24,272 dentists performed NHS activity in 2021-2022, an increase of 539 on the previous year.

These statistics are from the NHS Dental Statistics for England 2021-22 and also show 26.4m courses of treatment were delivered in 2021-2022, an increase of 120% compared to the previous year.

These figures do not show the number of dentists currently training and qualifying in the UK. Though they suggest that the UK’s dental shortage seems to be improving, the figures only refer to England. And as we’ve seen, residents in rural areas, such as in Scotland, may still be living in “dental deserts” where they’ll struggle to receive treatment.

Also, if there are only 539 more dentists in England in 2021-2022 compared to the previous year, then the workforce may not have grown enough to meet the demand for treatment.

How Many Dentists are Training and Qualifying in the UK?

In August 2021, the government adjusted the cap to allow over 9,000 places on medical and dentistry courses for 2021 student intake. By September, Further Education News was already reporting a record number of applicants to dentistry courses at UK universities.

Yet by July 2022, the BDA were reporting a “larger than usual” decrease in the number of dental graduated accepting foundation training places.

In March 2023, the BDA revealed that half of all dentists have cut their NHS commitment “with more to come”. Unfortunately, no matter how many dentists are currently training and qualifying in the UK, all figures suggest that the NHS dental shortage will not be resolved anytime soon.
