"Equipment and wiring that are incapable of "Equipment and wiring that are incapable of releasing sufficient electrical energy under releasing sufficient electrical energy under normal or abnormal conditions to cause normal or abnormal conditions to cause ignition of a specific hazardous atmospheric ignition of a specific hazardous atmospheric mixture in its most easily ignited mixture in its most easily ignited concentration." concentration."
Intrinsically Safe
Kaboom!!!
Hazardous Location Classes• Class I Flammable gases or vapors (Gasoline, Benzene, Ammonia, Toluene)
• Class II Combustible Dust (Corn, Untreated Wheat, Rice, Sugar)
• Class III Easily ignitable fibers or flyings (Cotton Fiber, Sawdust, Wood Shavings)
• Equipment that is intrinsically safe will be labeled for the hazardous location it is designed for.
• An example would look like this:BRIGHT STAR 2117Listed flashlight for Hazardous LocationClass I Group C & DClass II Group G
What to Look For
Boarding Team Safety
• Awareness: Know what kind of cargo the vessel you are boarding is carrying.
• Inspect your gear: Ensure that items you have with you are intrinsically safe
• When in doubt: Notify OPCON
• Consult the experts (MSO’s, national strike force, local HAZMAT teams)
Hazardous Cargo Labels/Placards

Biological Hazards
Confined Space Defined
• Not designed for continuous human occupancy• Limited means of entry and exit• Limited means of ventilation
Enclosed Space Defined
• 29 CFR 1914 (q) states “Any space,
other than a confined space, which is enclosed by bulkheads and an overhead.”• “May include cargo holds, tanks quarters and machinery spaces.”
Coast Guard Policy• Boarding personnel shall not enter any confined or enclosed spaces that are likely to have atmospheric hazards-oxygen depletion, flammable gases, toxic contaminants-until they have been certified safe for entry by a competent person
Qualified Individuals
•Marine Chemist•Certified Industrial Hygienist•Gas Free Engineer•Competent Person
• Oxygen Deficiency– 19.5% and below
• Flammable Vapors– 10% of LEL
• Toxic Atmosphere– No Entry if Present
Space Must be Tested

Neutron in counts per second
Low battery indicator
Gamma in microrems per hour
Visual radiation alarm
Inferred (IR) Port Used for transferring
data to PC. (Note: USCG will transfer data using the identiFINDER not the pager)
Sensors located on front side (opposite of belt clip side)
Controls and Display
When switched off, the pager will display the word OFF. If the screen is blank, replace batteries.
1.
To energize, press the MODE button for 1-2 seconds. Note: there is no beeping sound to indicate the unit has been energized (at this time).
2.
The pager will run a 20-second test and then beep once to indicate that it is energized.
3.
The pager will then calibrate. This will take about 40 seconds.
4.
Once calibrated, the pager will switch to dose rate (search) mode.
5.
Energizing
Input Changes
• Note: The pager will recalibrate and go to search mode after six seconds of inactivity. Therefore, it’s best to review steps before pressing any buttons.
The pager will automatically recalibrate and return to search mode after six seconds of inactivity.
All pagers should be set to 9.8
Change the threshold by pressing MODE (for lower number) and LIGHT (for higher number) buttons. Note: Lower number = greater sensitivity.
Press and release LIGHT button and the display should start blinking.
Press and hold the LIGHT button until display changes to look like #2 (may have different numbers).

2 Press and release MODE button.
This is the audible (sound) alarm setting. To switch the audible alarm on/off, use the LIGHT button. Press the MODE button to switch to the vibrating alarm.

Changing Alarm Types
Normal background radiation can vary from one environment to another. For this reason, it is best to calibrate upon boarding a ship
or boat.
The pager will calibrate.
The pager will then automatically return to search mode.
Press and hold the MODE button for two-three seconds, then release.
Calibration
When your pager alarms: •recalibrate•use pager to locate source.
If your pager reads 4,500 or more microrem per hour or displays “-OL-”, SMAC (stop, move away, alert, close off) and request Level II team.
Note: Once an alarm is triggered, update the background by calibrating before resuming search. It may be necessary to repeat this several times until the source is located.
The pager’s sensor is on the side opposite the belt clip. Be sure to expose this side to the direction of the source.
Searching
Searching (cont.)
Radiation Source / Level
Action …And …Response
Gamma increasing but below alarm threshold
Continue boarding
Be aware that low level “hits” could indicate a
distance source
Gamma alarm less than 4,500 μrem/hr
Determine source while
maintaining ALARA
Source is determined to be legitimate
Source is suspect or unlocated
Record findings and continue boarding
Request Level II support
Gamma 4,500+ μrem/hr or shows “OL” SMAC Maintain ALARA
Request Level II support if other that approved
shipment
Neutron 1-19 counts per second
Determine source while
maintaining ALARA
Alarm is infrequent in short duration (one-five seconds)
Alarm is consistent and continuous
Continue boarding
Secure situation and request Level II support
Neutron 20+ counts per second
SMAC Maintain ALARA
Use this table to help in decision making.
To turn pager off, press and hold LIGHT and MODE buttons. Light button must be pressed first.

The pager will display the word “OFF” when the pager is off. If the screen is blank, replace batteries.
Turning Pager Off
Battery
Coin
Cover to battery compartment
Insert battery positive side first.
The pager uses one AA battery. Use a coin or tool to access the battery compartment from the side of the pager.
Make sure pager is off before replacing battery.
Troubleshooting problems with the pager is limited to changing batteries.
