Arrival Notification

Guests, users, and visitors can notify BNL of their anticipated arrival date to BNL and confirm their place of work utilizing this portal. This will allow BNL to ensure that your training requirements are correct and allow BNL to make adjustments, if necessary.


If this is your first visit to BNL, review your training requirements. If you come to BNL often, you can easily check to see what training requirements may have lapsed since your last visit to BNL. Links to training courses are provided so that individuals can take their training on-line prior to arrival at BNL. Taking training prior to arrival will minimize check-in time for first-time visitors. For those that come to BNL routinely, this will allow you to be on your way to your BNL destination much quicker.
