EHS 004:
Definitions |
The terms used in this manual are defined as follows:
- Academic Unit
- For the purposes of EHS 116, “Minors in Laboratories,” any department, school, or college where the program will take place.
- Access Control
- For the purposes of EHS 121, “Utility Tunnel Access and Control of Hazardous Conditions,” the practice of restricting entrance to the tunnel system, including any room that has access points leading to the tunnel system, to authorized personnel. Physical access control includes human monitoring (by a guard or other attendant), through mechanical means such as locks and keys, or through technological means such as access control systems.
- Air Purifying
Respirator
- Personal protective equipment that purifies air by passing it
through a medium such as a cartridge. This includes half-face,
full-face, and powered air purifying respirators.
- Asbestos
- A generic term used to describe a number of naturally
occurring, fibrous silicate minerals that have been heavily used in
commercial and industrial applications. Asbestos exposure has been
associated with the development of a variety of diseases, including
cancer.
- ASU Community
- ASU and ASU-related employees, graduate students, undergraduate students, postdoctoral researchers, visiting researchers, volunteers, and service providers
- Authorized Driver
- An ASU employee or volunteer who is required in the course and scope of employment or volunteer activity to drive an ASU vehicle for official business purposes, and meets the following requirements:
- has a valid driver's license
- has completed and is current with required training
- has a driving record in good standing (less than 6 points)
and
- has submitted a Driver's Authorization Form to Human Resources.
- Automated External
Defibrillator (AED)
- A device that analyzes the
heart’s rhythm for an abnormality and, if necessary, directs
the rescuer through voice prompts to deliver an electrical shock to
the victim. The shock, called defibrillation, may help the heart
reestablish an effective rhythm on its own.
- Bloodborne Pathogens
- Pathogenic microorganisms that are present in human blood and
can cause disease in humans. These pathogens include, but are not
limited to, the hepatitis B virus (HBV) and the human
immunodeficiency virus (HIV).
- Cardiac Arrest
- Cardiac arrest involves an abnormal heart rhythm. The heart’s electrical impulses suddenly become
chaotic, causing the heart to cease pumping blood effectively.
Unless a normal heart rhythm is restored, death will follow within
a matter of minutes.
- Common Areas
- Areas that are used by or accessible to all occupants in
multifamily housing structures.
- Conductor
- For the purposes of EHS 118, “Electrical Safe Work Practices,” the following types of conductors are defined:

- Insulated: a conductor encased within material of composition and thickness that is recognized as electrical insulation.
- Confined Space
- A space that:
- is large enough and so configured that an employee can bodily
enter and perform assigned work
- has limited or restricted means for entry or exit
and

Examples include, but are not limited to, tanks, vessels, silos,
storage bins, hoppers, vaults, sewers, pits, excavations, tunnels,
and trenches.
- Exit/Exit System
- All contiguous areas that can be occupied between the occupied
space and the building exit.
- Exposed (as applied to live parts)
