You will receive credit for all qualifying experience, including volunteer experience.Education:

This position does not allow substituting education for experience.
Physical Demands: The work of the Security Guard regularly includes long periods of standing or sitting in a limited space, or standing outside in inclement weather. The Security Guard is expected to perform these duties 8 hours or more per shift. The work also includes bending, reaching, and stooping while using hand-held magnetometer. Must be able to lift 30 pounds continuously, up to 50 pounds occasionally. The Security Guard may occasionally have to move magnetometers and/or x-ray machines. Must be able to distinguish objects on the screening equipment monitor and be able to distinguish basic colors and shades of color, each color displayed and explain what each color signifies. Must have correctable vision to recognize, distinguish differences, and identify images on x-ray monitors, and read typed material. Must be able to hear and respond to the spoken voice and to audible alarms generated by screening equipment in an active checkpoint environment. Duties require manual dexterity with comparatively free motion of finger, wrist, elbow, shoulder, hip, and knee joints to be able to efficiently and thoroughly manipulate and handle baggage, containers, and other objects subject to security processing. Must also possess sufficient dexterity and capability to conduct thorough hand-metal detector and, only as necessary, pat-down search procedures over an individual's entire body. Security checks of buildings require walking. The Security Guard may have to walk all or part of the steps inside the legs of the Arch, the tram load zones, or any of the stairways on the Arch grounds or in and around the Old Courthouse. Must be able to tactfully interact with a multitude of visitors simultaneously, many of which are highly anxious to get into the Arch quickly, while doing pre-screen checks of visitors' possessions on the entrance ramps. There is a high-stress component to aspects of the Security Guard's work assignment. Work can be emotionally stressful due to the sheer volume of visitors contacted within an 8 hour shift or due to the potential unknown risks that arise at the checkpoint at any given time that include risks to personal safety.
Work Environment: The Security Guard works closely with others and in constant noise during days of heavy visitation. Work fluctuates between indoors within a climate controlled facility and outdoors performing package pre-screening functions on the Arch entrance ramp, roving patrols of grounds or stand a fixed post during a special event such as "Fair St. Louis." The Security Guard is subjected to bad weather when work is performed outside. Shift work is required including evenings, weekends, holidays, and occasionally covering a 24-hour period in cases such as an emergency or special event. Unscheduled or scheduled overtime and call-outs may be required. Work during emergencies may include prolonged periods of time without rest or breaks. At a fixed post, the Security Guard performs magnetometer and x-ray machine operations at one of two security checkpoints located in the Arch Complex. Operation of x-ray equipment exposes the Security Guard to a level of risk to radiation exposure, therefore all specific safety procedures and other precautions are mandatory. The Security Guard is exposed to high risk and potentially dangerous situations. Any emergency law enforcement operations that the Security Guard may become involved with require work in or about hazardous environments, exposure to dangerous persons and substances, and potential exposure to infectious diseases, secondary explosive devices, or biological or chemical contamination. They will also be verbally or physically confronted with disgruntled, disorderly, or highly volatile persons who may not want to comply with directions. At the security checkpoint, Security Guard will encounter mentally disturbed individuals, uncooperative and/or disorderly individuals, persons who are intoxicated and/or under the influence of drugs, persons with loaded illegal firearms, various illegal knives or other illegal or dangerous weapons, illegal drugs or other unknown substances, and persons carrying explosive devices. The Security Guard must remain calm and use good judgment in appropriately dealing with the situation including obtaining assistance from law enforcement Park Rangers without causing chaos or civil disorder. Gateway Arch National Park, as identified for potential terroristic activity, is operating at a heightened security awareness level which creates varying stressors that the employee must effectively cope with.
