Welcome to the Atmospheric Radiation Measurement Program's Southern Great Plains (SGP) Cloud and Radiation Testbed (CART) site. This U.S. Department of Energy (DOE) site is managed by Argonne National Laboratory (ANL). It is very important that all visitors comply with all DOE and ANL safety requirements, as well as those of the Occupational Safety and Health Administration (OSHA), the National Fire Protection Association, and the U.S. Environmental Protection Agency, and with other requirements as applicable.
2 VISITOR SIGN-IN AND SIGN-OUT
All visitors to the SGP CART site are required to complete a Visit Request Form before the visit.
Visitors are required to sign the visitor sign-in log and get a visitor badge anytime they visit the Central Facility site; likewise, be sure to sign out if you are leaving the site, even if it is for lunch and you plan to come back to the site. It is very important that you sign in and sign out so that, in case of an emergency, we have a way to track where you are. The visitor sign-in log is located in the Central Facility Control Trailer.
Visitors going to SGP CART Extended Facilities or other SGP CART facilities are required (1) to make a check-in call from the site to notify Site Operations (405-388-4053) of the time of arrival on-site and (2) to call again and notify Site Operations of the time of departure. Any pertinent information regarding the site or operations at the Extended Facility, such as severe weather, will be coordinated between Site Operations and the visitor during the check-in call.
When performing work at locations other than the main site, telephone contact may be used to communicate with Site Operations after your initial sign-in. You must have a cellular telephone when working at remote sites, and the number of that telephone must be given to Site Operations so you can be contracted in the event of an emergency.

A fill hose is provided at the 160-L Dewar flask location. When using liquid nitrogen at any SGP facility, the following PPE is required to be worn:
Full face shield
Chemical full-body apron
5 SMOKING, ALCOHOL, DRUGS, AND FIREARMS
Smoking is prohibited inside any of the buildings, enclosures, and trailers at the SGP CART site. Smoking is allowed outside in non-fire-danger areas only. Smoking debris is to placed in authorized receptacles only.
Alcoholic beverages, illegal drugs, and firearms are strictly prohibited at any SGP CART facility or site.
During your visit, we want you to be aware of some of the hazards that you might encounter and also to become familiar with safety rules designed to mitigate these hazards. We have divided them into four hazard categories as follows:
6.1 Electrical Hazards
6.1.1 De-energizing Equipment
Always de-energize electrically hazardous equipment before performing maintenance on it; that is, never work on live circuits that could expose personnel to an electrical hazard. If you are unsure as to whether or not the work you are planning involves electrical hazards, notify the Site Safety Officer before performing the work.
6.1.2 Lock-Out/Tag-Out Standard
We abide by OSHA's Lock-Out/Tag-Out Standard, which states that you will lock out and tag out an electrical device before working on it, so that it cannot be re-energized accidentally. Lock-out/tag-out procedures and equipment are supplied by the Site Safety Officer.
6.1.3 Gound Fault Circuit Interrupters
All outdoor receptacles, all receptacles located within 6 ft of exterior doors, and all receptacles around sinks or other water supplies shall be protected by ground fault circuit interrupters.
6.1.4 Excavation and Penetration
If you need to excavate or penetrate the ground or an existing facility, enclosure, or trailer wall, please contact the Site Safety Officer for approval before starting work. Excavations in the ground require a digging permit.
6.1.5 Portable Electrical Equipment
All portable electrical equipment (except double-insulated tools) must have a three-prong grounding plug. All portable electrical equipment shall be in good working order and is subject to inspection by the Site Safety Officer or his or her designee before use.
6.1.6 Electrical Extension Cords
If electrical extension cords are to be used, they shall be the three-wire type and have a hard or extra hard usage rating. They shall be in good condition and not compromised in any way. They shall not be connected in series, spliced, or taped. The Site Safety Officer will inspect all extension cords coming to the SGP CART site.
6.1.7 Aluminum and Metal Ladders
Because of the conductivity of aluminum and other metals, no aluminum or metal ladders are allowed on-site. Ladders brought to the site must be in good working condition.
6.2 Chemical Hazards
6.2.1 Hazard Communication Standard
We abide by OSHA's Hazard Communication Standard. Haz/Com is also known as the "Employee Right To Know Law" and is commonly addressed in a Chemical Hygiene Plan at laboratories and universities and in private industry.
The OSHA standard specifies that personnel have the right to know of chemicals that are used on-site. This requirement is accomplished through the chemical manufacturer's Material Safety Data Sheet (MSDS), labels on products or containers, and the education that this standard exists.
6.2.2 Bringing Chemicals On-Site
If you are bringing any chemicals to the site, please identify them on the applicable previsit forms, or notify the Site Safety Officer. Include any chemical item, even one as benign as distilled or drinking water. All chemicals brought to the site shall be labeled and have a Material Safety Data Sheet.
6.2.3 Flammable Chemicals
All flammable chemicals shall be stored in an approved flammable storage cabinet.
6.2.4 Chemicals Used in Quantity at the SGP CART Site
Chemicals that the SGP CART site uses in quantity are helium, liquid nitrogen, and carbon dioxide.
Helium: Helium is used to launch the weather balloons and is an asphyxiant. Our supplies are kept outside.
Liquid Nitrogen: Liquid nitrogen is used to cool certain instruments. It is a cryogenic material, and hazards consist of asphyxiation and burns. The SGP CART site's main supply Dewar flasks are stored outside, and quantities needed for instrument use are taken inside trailers in smaller Dewar flasks. All personnel are required to wear personal protective equipment and obtain approval from the Site Safety Officer when using liquid nitrogen.
Carbon Dioxide; Carbon dioxide is an asphyxiant and is used in the Central Facility's fire suppression systems. The Central Facility has three trailers with fire suppression systems; they are the calibration trailer, the optical trailer, and the Raman lidar trailer. The fire suppression system works by dumping copious amounts of carbon dioxide in the trailer, lowering the oxygen content so that it suffocates the fire. It is important to get out of these trailers quickly once a CO2 discharge alarm activates. If an audible horn sounds and you see a strobe light, immediately exit the trailer. Note: At the optical trailer and calibration trailer, there is a large red abort button near the door. If for some reason you need extra time to get someone out, press that button and hold it in; the system will not discharge while the button is held in. Once the button is released, you have 25 seconds before the system will discharge.
6.3 Nonionizing Radiation Hazards
This site contains radio frequency, microwave, and laser radiation. All radiation is well contained, and appropriate engineering controls are in place to protect personnel; however, if you plan to work on instruments and are required to deliberately disable safety engineering controls (e.g., a laser interlock), then you must gain approval from the Site Safety Officer before commencing any work.
6.4 Natural Hazards
The SGP CART facilities are located in rural Oklahoma and Kansas, and there is a myriad of natural hazards one might encounter. Some of the more evident natural hazards are the following.
Rural areas have uneven ground surfaces, protruding rocks, tree branches, and other vegetation that may make walking somewhat difficult. Remember to always look before taking a step, and avoid possible tripping hazards.
Oklahoma and Kansas have many different species of snakes, and most are nonpoisonous. The bite of a nonpoisonous snake can cause pain and infection but is rarely serious. Three types of poisonous snakes are found in Oklahoma and Kansas, and their bites can cause serious illness and even death. The following poisonous snakes are found in the CART area:
Eastern, western, and pygmy diamondback rattlesnakes
First Aid for Snakebite
1. Stay calm.
2. Look at snake for identification (shape of head, color, and markings).
3. Seek help.
4. Keep the bite at the level of the heart.
6.4.3 Arachnids and Insects
Black Widow: The black widow is a small, shiny spider, less than half of an inch long but with a leg span of up to 2 in., with a red hourglass shape on its underside. A bite from a black widow spider can cause severe pain and muscle spasms, heavy sweating, stomach cramps, nausea, vomiting, tightness in the chest, breathing difficulty, and a sharp rise in blood pressure.
Brown Recluse: The brown recluse spider is brown or brown-yellow in color and has a dark violin-shaped area on the back. The brown recluse is found under rocks and woodpiles, as well as in closets and attics. A bite from the brown recluse can cause severe pain, reddening, blistering, and death of the tissue, followed by deep ulceration at the site of the wound. The bite may not be noticed at first. Pain at the bite site begins one to four hours later.
First Aid for Spider Bite: Try to identify the type of spider. If possible, kill the spider without smashing it beyond recognition. Call the Safety Officer or Shift Supervisor, and advise them of the situation. Then seek medical attention for your bite.
The Lone Star tick, the American dog tick, the brown dog tick, and the black-legged tick or deer tick frequent Oklahoma and Kansas. Most ticks are capable of transmitting a variety of diseases, including Rocky Mountain spotted fever, Colorado tick fever, Lyme disease, and even tularemia (a disease that causes toxins in the blood; high fever is a symptom).
First Aid for Tick Bites:
1. Remove ticks with tweezers, with a slow steady squeeze.
2. Wash area thoroughly with soap and water.
3. Mark the date of the bite on the calendar. If any flu-like symptoms (such as fever, muscle pain, extreme fatigue, headache, and chills), joint pain, swollen glands, or a rash appears, see your physician. Symptoms of Lyme disease may not develop for up to two months.
To avoid ticks, tuck pant legs into socks; spray an insect repellent on pants.
126.96.36.199 Fleas and Chiggers
To avoid exposure to fleas and chiggers, do not walk in uncultivated areas or heavy vegetation. Spray an insect repellent on pants.
188.8.131.52 Gnats and Mosquitoes
Gnats: Although most gnats are not bothersome, Oklahoma and Kansas have a gnat (the buffalo gnat) that bites much like a mosquito. To repel these gnats, apply Avon Skin-So-Soft or vanilla extract.
Mosquitoes: To avoid contact with mosquitoes, spray an insect repellent on the outside of clothing and, if repellent is designated for it, spray on bare skin.
184.108.40.206 Blister Beetles
Blister beetles are small insects that have yellow and black strips running the entire length of the body. Their bite produces immediate pain, redness, itching, and swelling that can persist for hours.
220.127.116.11 Hornets, Wasps, Bees, and Scorpions
Hornets, Wasps, and Bees: Hornets, wasps, and bees all have a stinger, but honey bees have a stinger attached to a poison sac that is left in the wound when a sting occurs. Wasp and hornets retain their stinger and may sting repeatedly.
First Aid for Hornet, Wasp, or Bee Sting: If a stinger is present, remove the stinger from the wound by scraping a blunt object, such as a dull blade, across the wound. Symptoms usually resolve within a few hours. If symptoms such as difficulty in breathing or rapid severe swelling occur, seek medical attention.
Scorpion: All scorpions in Oklahoma and Kansas can produce a painful sting, but serious life-threatening symptoms are rare.
First Aid for Scorpion Sting: First aid is similar to a wasp sting.
18.104.22.168 Cattle and Electric Cattle Fences
At times, the pasture outside of the instrument areas may contain cattle. Cattle are, for the most part, docile animals. Please do not provoke them.
Because of the cattle, all exposed instrumentation, shelters, and platforms have either a single-strand electric fence or a barbed-wire fence. Be careful not to touch the electric wire because a mild shock is likely. All electric fences have gates; please use them. Be careful around barbed-wire fences because the small barbs are very sharp and can cause injury.
22.214.171.124 Badgers, Skunks, and Coyotes
Badgers: The badger is fairly prevalent in most parts of Kansas and Oklahoma. Badgers are small (average, 20 lb) mammals that feed on small rodents, fruits, and roots. They have very sharp teeth and long sharp claws and are quite aggressive. In cooler weather, the badger will make a burrow and remain there for several months. The opening to the burrow is 6 to 8 inches in diameter. The badger is a defensive animal and will usually only attack if provoked. Should you spot a badger hole, keep your distance, and do not put your feet or hands into the hole.
Skunks: The skunk is fairly prevalent in most parts of Kansas and Oklahoma. This small mammal produces a very unpleasant odor when excited or threatened. Please keep your distance from these animals. They also can carry rabies; if bitten, seek medical attention immediately.
Coyotes: The coyote is fairly prevalent in most parts of Kansas and Oklahoma. Coyotes are small dog-like mammals. They attack small animals and livestock. Coyotes are, for the most part, very shy and afraid of humans. They do, however, sometimes carry rabies; so, if bitten, seek immediate medical attention.
7 EMERGENCY SERVICES
Local authorities (to include police, fire, and medical services) have been identified for each of the SGP CART site facilities. Routine and emergency coordination for these emergency services will be provided through telephone contact with the Central Facility Control Center at 405-388-4053.
8 EMERGENCY SITUATIONS
If emergency situations arise, first take the immediate required action (first aid, cardiopulmonary resuscitation [CPR], etc.), and then contact the Central Facility to advise of the situation. More information and guidance on emergency situation actions and reporting will be provided by the contact with the Central Facility.
9 SEVERE WEATHER
The Central Facility will establish the "site weather alert condition" (red, yellow, or green). The Central Facility has access to near real-time weather radar displays, plus access to the Internet weather advisory services, including the National Weather Service advisories and radar displays.
Coordination between the Central Facility and field personnel shall allow for sufficient advance warning of impending severe weather.
9.1 Site Weather Alert Condition
The SGP CART site currently uses a three-color system to denote the weather alert status for any given site. The site weather alert condition status will be established and modified as needed by coordination between the Central Facility and applicable personnel on-site. The following categories define the SGP CART weather alert condition status.
9.1.1 Green Normal Condition
No weather watches or warnings are in effect for the site area.
9.1.2 Yellow Watch Condition
The yellow weather alert condition is established when forecasted weather conditions may result in a severe weather situation. Severe weather is classified as thunderstorms, tornadoes, heavy rain or snow, flash floods, winter storms, heavy fog, or any other weather condition that may hamper or affect site operations and personnel. During the watch condition, Central Facility and field personnel shall maintain their alertness to the surrounding weather conditions. Any changes noticed shall be immediately coordinated between the Central Facility and field personnel via telephone.
9.1.3 Red I Warning Condition
The red I weather alert condition is established when forecasted severe weather is imminent. The important aspect of the red I condition is for the field personnel to implement acute heightened awareness of the surrounding weather conditions and to be aware that the potential exists for a condition that may require field personnel to seek shelter at any moment. If the severe weather includes lightning, large hail, and high winds and if these events are observed within 5 mi of the site and are moving toward the site, all outside work shall be immediately stopped. At the Central Facility, personnel shall remain inside the designated site building. Field personnel shall evacuate the site to a safe location. On reaching the safe location, field personnel shall call and notify the Central Facility of their location, status, and any other relevant information until the weather threat has passed.
9.1.4 Red II Warning: Take Cover
The red II weather alert condition denotes the threshold for immediate evacuation to an adequate storm shelter. At the Central Facility, all personnel shall immediately proceed to the storm shelters, taking the cellular telephone and flashlight.
At remote facilities without storm shelters, personnel who have not otherwise sought a safe location shall immediately seek a low-lying area, such as a ditch or ravine, for cover.
Upon assessment that the severe weather event has passed, personnel shall cautiously exit the storm shelter and immediately survey the area, noting any observed damage.
After completion of the initial damage assessment, call and notify the Central Facility that you have safely survived the severe weather event, and relay information on any damage observed. The Central Facility will advise what additional actions need to be taken.
9.2 Hot Weather Exposure
Three heat-related illnesses can be caused by hot weather exposure.
9.2.1 Heat Stroke
Heat stroke is life-threatening. The victim's temperature control mechanisms stop working. The body temperature can rise so high that brain damage and death may occur if the body is not cooled quickly.
Symptoms of Heat Stroke: Symptoms include dry, hot red skin and a very high body temperature.
First Aid for Heat Stroke: First aid is to cool the victim down as quickly as possibly, and call for medical help.
9.2.2 Heat Exhaustion
Heat exhaustion is less dangerous than heat stroke. Heat exhaustion typically occurs when people work in a warm, humid place where body fluids are lost through heavy sweating.
Symptoms of Heat Exhaustion: Symptoms include cool, moist pale or red skin or heavy sweating, dilated pupils, headache, nausea, and dizziness.
First Aid for Heat Exhaustion: First aid is to get the victim into a cooler place. Place victims on their back, with feet up. Cool by fanning or applying cold packs, and give 1/2 cup of water every 15 minutes.
9.2.3 Heat Cramps
Heat cramps are muscular pains and spasms due to heavy exertion and usually involve the abdominal muscles and/or the legs. It is generally thought that the loss of water and salt from heavy sweating causes cramps.
9.2.4 Hot Weather Hazard Prevention
Drink plenty of liquids such as water and fruit and vegetable juices. Avoid soda pop and coffee.
Restrict strenuous activity during hot periods.
Wear loose-fitting light-colored clothing, preferably made of natural fibers such as cotton. Man-made fibers do not absorb water well. Wear a hat.
10 SAFETY VIOLATIONS/DISCREPANCY
The Site Safety Officer and Site Operations Manager have the authority to cease operations of any activity that is in violation of federal, state, or local safety regulations or is in violation of the items covered in this orientation. Any person has the authority to cease operations that are immediately dangerous to life and health (imminent danger). The Site Safety Officer or the Site Operations Manager (or both) shall be immediately notified of any safety or emergency incident occurring at any SGP CART facility.
