A |
|
|
Conditions that are unfavorable, harmful, or detrimental
to or for work, such as excessively high or low ambient temperatures,
exposure to adverse conditions such as ODH (Oxygen Deficiency Hazards),
radiation, weather, corrosive fumes, high traffic (vehicles and/or people),
or hazardous locations which would require a SOP or OSP. (Chapter 6140 Cranes&Hoist) |
|
|
Equipment that utilizes electrical energy for
electronic, electromechanical, chemical, heating, lighting, or similar
purposes. For further information on this equipment, refer to Chapter 6230
Electronic Equipment Safety. (6220) (6230) (6230T1)

|
|
acceleration system/component |
Devices capable of accelerating particles to
energies of > 10 keV. This includes ac, dc, or
RF voltages in excess of 10 kV applied in or near a low pressure vessel.
(Prompt radiation controls are recommended for equipment capable of
generating a final particle energy ≥ 25 keV.)
(6311 PromptRadCon) |
|
Accelerator Operations Directives (AOD) |
details the approach utilized by
Accelerator operators to comply with Jefferson Lab policy, procedures, and
documentation requirements. (3130 FELExpRev) |
|
Accelerator Safety Order |
A reference document from DOE (DOE Order 420.2,
Safety Of Accelerator Facilities, May 26, 1999) that provides guidance for
ES&H issues associated with accelerators and accelerator-based
experiments. Applicable portions of this document have been included in
Appendix E of the JSA/Jefferson Lab contract with DOE. (3130 FELExpRev) |
|
Access Control System (ACS) |
A system whose purpose is to reduce the likelihood
of unauthorized or inadvertent access to areas presenting a radiation hazard to
personnel. (6311 PromptRadCon) |
|
Acclimatization |
The physiological adjustment process that occurs
when a healthy worker accustomed to a temperate environment begins to work in
a hot environment. These adjustments should take place over a period of days
(up to 1-2 weeks), during which time spent may be gradually increased safely.
(6640HearConserv) |
|
Action Level |
A predetermined level which, when reached,
triggers a particular action. (e.g. 30
μg/m3 for eight hours concentration of lead
particulates in the air 30 μg/m3 for eight
hours triggers stringent monitoring (Chpt 6670); or
1 rem in 1 year for an individual is the cumulative
annual exposure which triggers Director approval to allow continuation of
work. |
|
action limit |
The evaluation of thermal stress, action limits
may be used, such as temperature cutoffs or temperature index cutoffs. When
an action limit is reached, the supervisor shall initiate action to prevent
thermal illness or injury. (See Appendix 6670-T3 Assessment of Thermal Hazards.)

activate |
Cause to become radioactive. (6315 EnviroMonitorIonRad) |
|
active controls |
Controls that require some action to prevent or mitigat |
