BLOCK 6: NON-IONIZING RADIATION - Unit 5: Electromagnetic Frequency Radiation Controls (complete) Flashcards
__________ is not authorized for control of Air Force EMF hazards.
PERSONAL PROTECTION EQUIPMENT (PPE)
When dealing with EMF radiation, only engineering and administrative controls are to be considered. EMF protective clothing is considered not acceptable for Air Force use, and the USAF Surgeon General does not advocate the use of EMF sensors, detectors, alarms, area monitors, and personal devices. Since 1998, these items are considered to give a false sense of protection.
Occurs when the emitter is prevented from transmitting a signal (EMF radiation) once the antenna has reached a predetermined azimuth region (the term azimuth refers to using an angular measurement in a spherical system).
AZIMUTH BLANKING
Used to absorb EMF energy while an EMF system is being tested.
DUMMY LOADS
Automatically switch off the EMF emitter when a door, hatch, or other entry point is breached.
INTERLOCKS
Panic buttons for emergency use only are usually installed inside rooms where antennas are located.
KILL SWITCHES
Required for controlled areas where frequencies are below 30 MHz and where electric burns are the primary hazard. Burns are the result of the induced current that may occur while working with the equipment.
ELECTRIC SHOCK OR BURN SAFETY EQUIPMENT
Informing the owner/operator of when you or someone else will be entering the area where the emitter poses a hazard will help prevent workers from inadvertently entering areas that could exceed the MPEs.
PRIOR COORDINATION
Prior coordination can be implemented to work in both directions, whereby emitter controllers or operators and maintenance personnel are both made aware of each other’s actions before proceeding into the hazardous area.
Conducted for all Air Force employees who routinely work or enter areas where EMF radiation levels may exceed the Maximum Permissible Exposure (MPE).
EMF TRAINING
This training requires the shop supervisor to train new individuals initially upon assignment and annually to refresh the EMF safety and health concepts. Additionally, training may be performed when there are changes to the emitter or if a new emitter is brought in.
Information on ____________________ during training should include the following:
Ensuring that all workers are properly trained on the hazards associated with EMF radiation
Verifying that required warning signs and safety devices are in place or properly set before beginning work
Performing jobs in a manner to keep exposures to EMF radiation as low as reasonably achievable (ALARA) and below the MPE
Ensuring all parties involved understand procedures/signals to be used for current operations
Ensuring workers report suspected or alleged overexposures to EMF radiation to supervisors, responsible area supervisor, unit commander, and medical facility
SAFE WORK PRACTICES
Commanders and supervisors must inform visiting guests that there is a chance they might enter an upper tier environment. This isolation of the EMF hazard is an example of a _______________.
CONTROLLED AREA
Flashing lights/audible signals are used in areas with high EMF radiation levels to clearly identify EMF transmission. These are normally located _______________ the hazardous area/facility. These warn other workers of the potential hazard in the area.
OUTSIDE
AFI 48-109, Electromagnetic Field Radiation Occupational and Environmental Health Program, outlines mandatory posting requirements for upper and lower tier areas in which _______________ should be placed where they are visible from all directions of approach.
WARNING SIGNS
Administratively, physical controls such as _____________________________________ are typically used to eliminate or minimize the occurrence of exposures.
FENCES ; CONSTANT OBSERVATION ; ROPES/CONES WITH WARNING SIGNS
