If it does go wrong and a customer has an allergic reaction

Sometimes it can be hard to tell if someone is having an allergic reaction. Other serious conditions can have similar symptoms. But even if you're not sure what the problem is, if someone is finding it hard to breathe, if their lips or mouth are swollen, or if they collapse, you should:

• call 999 immediately and describe what is happening.
• don't move the person, because this could make them worse.
• send someone outside to wait for the ambulance and stay with your customer until help arrives.
