Abstract
A ladder is disclosed which includes gate members to block access to the ladder. The gate members preferably include a warning against unauthorized use of the ladder. The ladder may be mounted on wheels such that it may be transportable, for uses in environments such as warehouses. Since these environments may be exposed to customer use, the warnings may prevent unauthorized use of the ladder by customers.
