What are skin and respiratory sensitisers?

Substances at work may cause allergies when breathed in, or when they come into contact with the skin.

Such substances are called skin and respiratory sensitisers.

They can cause permanent damage to the skin, nose, throat, and lungs.

If this happens, further exposure, even to minute quantities, may result in allergic symptoms.

Effects of skin and respiratory sensitisers

Symptoms vary depending on which body system is affected.

Effects on the respiratory system can be the runny, itching eyes and nose typical of hay fever. These may be followed by more severe symptoms typical of asthma such as:

  • wheezing
  • tightness of the chest
  • breathlessness
  • coughing.

Symptoms of the skin can be itchy, dry, red and cracked skin typical of irritation. These may be followed by more severe dermatitis symptoms such as:

  • bleeding
  • spread of symptoms to other body parts.

When do symptoms occur?

  • symptoms can occur on first exposure to the substance
  • most cases of sensitisation occur during the first two years of exposure, but more often within the first few months
  • symptoms can also occur after decades of exposure
  • symptoms are often most severe in the evening, or during the night, and so the employee often does not associate them with work
  • there can be an improvement in symptoms during weekends and holidays
  • with continued exposure, symptoms become worse
  • once established, respiratory attacks can be triggered by other things like tobacco smoke, cold air and exercise
  • skin attacks can occur with exposure to household cleaning products.
