The event organiser is responsible for safety and security at the event. If necessary, contact the library in advance regarding any matters and questions regarding safety and security oodi.tilat(at)hel.fi.

There are guards present at Oodi throughout its opening hours, but they cannot be used as security guards for individual events.

If separate security services are required for the event, Oodi should be notified of this requirement in advance oodi.tilat(at)hel.fi. Security services must be ordered from Palmia.

Oodi does not provide cloakroom services for the facility which is why such services must be ordered from an external operator. Such services and the location of the cloakroom must first be agreed upon with Oodi oodi.tilat(at)hel.fi.
