There are two types of HASPs that you can purchase...

Choose a Single-JHA HASP if all hazards and control measures are the same for all site tasks, operations, and locations covered by the HASP.  Single-JHA HASPs are usually used for simple sites with limited hazards or for limited task-specific HASPs. Chose a Multiple-JHA HASP if there are different hazards and control measures needed for the tasks, operations, and locations covered by the HASP.  Multiple-JHA HASPs are the most common type of HASP.

A Single-JHA HASP can be upgraded to a Multiple-JHA HASP at a later time.
