Sensitiser is often used to refer to chemical substances. Sensitisers can cause an allergic reaction in the lungs or skin. Some examples:-
• Perfumes used in soaps, moisturizers, and cosmetics.
• Preservatives and antibacterial chemicals added to liquids.
• Chemicals that add thickness or colour.
• Formaldehyde resin in nail care products.
• Sunscreens found in moisturizers, lip balms, and makeup.
You can identify sensitisers from the hazard statements displayed on pre-packaged chemicals. E.g., H334 may cause allergy or asthma symptoms or breathing difficulties if inhaled.
If a substance with either statement above is used in the workplace, the potential for allergic reaction and the health impact of long-term exposure must be highlighted in your risk assessment.
What you can do to try and prevent allergic reactions:
• Eliminate - do you need to use the substance?
• Substitute – can a safer alternative or a smaller amount be used?
• Engineering controls – can you separate people from the hazard?
