No official protocol but be careful as first aid tends not to include medication yet Piriton is useful. Could the faint be unrelated/due to psychological response to being stung?
I'd personally say:
- Remove the sting
- Provide advice
- Monitor them as far as practicable even if this is just talking and give them the option to stop/sit out for a bit
- Have incident forms
Advice would be along the lines of:
- People having a variety of reactions to stings from nothing all the way to anaphylaxis.
- Sometimes there can be lots of swelling, sometimes it can be itchy days later.
- If they are concerned they should seek medical advice, obviously 999 in an emergency such as struggling to breathe.
- Piriton (chlorphenamine) can be helpful if taken early on.
- In rare cases, infections at the site of the sting can occur too so they should monitor for this and seek medical advice if concerned.
Obviously this would be advice better given before they start the session anyway... Including having emergency contact details.
This is just off the top of my head, others who are involved in associations may be able to give a better answer. HSE would probably also be able to advise although this may be stirring the proverbial hornet's nest!
Also having a trained first aider around for each session is probably wise.
