The Met Office has warned that the UK "could be at risk later this week", if the Grimsvotn volcano continues erupting at the same rate.
"Where the plume will go depends on what happens with the weather, and if the volcano continues to erupt," a Met Office spokesman told C&IT. "The Met Office is monitoring the situation."
The eruption comes a year after ash from the Eyjafjallajokull volcano spread across Europe, causing disruption to events including T-Mobile's incentive to St Lucia, and Vauxhall's international conference.
During last year's eruption UK airspace was shut down completely by the authorities as a precaution but this time airlines will make their own decisions about whether it is safe to fly.
Bauer said all the Icelandic exhibitors had arrived at Imex, which is kicking off in Frankfurt with its association day today (23 May) and runs until Thursday (26 May).
"We have full plans in place, having had to formulate them last year," explained Bauer. "At present we are monitoring the situation closely but have not had to activate any plans.
"There is no specific travel advice coming in at the moment. The situation looks stable and unlikely to affect us in any serious way. If hosted buyers have any worries at all they should contact us direct and also check the website for updates. If travel plans do become affected, Imex will make sure that hosted buyers are extremely well looked after."
