Course Introduction
NSTC Course 055 Hypergol Systems: Design, Buildup, and Operation
BACKGROUND
This course was developed by personnel at the NASA JSC White Sands Test Facility in conjunction with the NASA Safety Training Center (NSTC). The NSTC was established in May 1991 by the NASA Headquarters Safety Directorate to provide up-to-date, high-quality, NASA specific safety training on location at NASA centers, or simultaneously to multiple centers over the Video Teleconferencing System (ViTS). Our desire is to establish and maintain a strong, long-lasting relationship with all NASA centers in order to fulfill your safety training needs on a cost-effective basis. Our ultimate goal is to provide a positive contribution to safe operations at NASA.
COURSE DESCRIPTION
NSTC Course 055 is a 2-day course discussing the safe usage of hypergols (hydrazine fuels and nitrogen tetroxide). During the course we will identify the hazards associated with hypergols including toxicity, reactivity, fire, and explosion. Management of risk is discussed in terms of the primary engineering controls – design, buildup, and operation; and secondary controls – personal protective equipment and detectors/monitors. The emphasis is on the design and buildup of compatible systems and the safe operation of these systems by technicians and engineers.
COURSE GOALS AND OBJECTIVES
The NSTC’s goals in teaching this course are:
To increase safety awareness; To provide useful information and references; To enable attendees to identify and evaluate typical hazards of hypergols and
hypergol systems.
INTENDED AUDIENCE
Those who would benefit from this course include engineers, technicians, plant managers, and operators involved in hypergol system design, buildup, operation, and maintenance. This course would also be appropriate for safety and health professionals involved in monitoring and evaluating the operation of hypergol systems.
INSTRUCTIONAL TECHNIQUE
The instructional technique used will be primarily lecture and in-class videos. We do encourage in-class discussion to develop student understanding of the concepts, practices,
2
and techniques discussed. We encourage students to participate during all parts of the class; and if you have a question, a comment, or a personal experience that would contribute to the subject - please speak up. We also encourage you to ask the instructors to discuss issues specific to your use of hypergols so we can tailor the class to your Center’s needs.
COURSE MATERIALS The course notebook provided with this class is intended not only for your use in following the classroom presentation, but also for future reference. We hope this notebook is not a trophy adorning your bookshelf, but rather a reference tool you go back to again. We encourage you to follow along and review the material during the class so you can ask any questions you may have.
COURSE EVALUATIONS
Course critiques are very important to us. We are very interested in your impressions of the class materials and presentation, and your suggestions for improvement. The NSTC staff and the course instructors will review each and every critique, and your written comments will be provided to the point-of-contact at your center.
COMPLETION CERTIFICATES
We will send you an NSTC course completion certificate along with a class roster after the class. NASA Headquarters will sign these course certificates. Please fill out the course attendance roster fully and legibly for each class, as we will use it to track attendance, to prepare course completion certificates; and potentially to contact you in the future with NSTC news. In order to receive credit for course attendance, you must personally attend approximately 2/3 of the course. Course instructors will have the final say on who should receive credit for the course.
CONTINUING EDUCATION UNITS (CEUs)
This course has been approved for the award of up to 1.2 Continuing Education Units (CEUs) to students. The primary purpose of a CEU is to provide a permanent record of the educational accomplishments of an individual who has completed one or more significant non-credit educational experiences. CEUs can be used to update and maintain professional certifications. In order for this award, we will be taking attendance every day on a roster, which requires your signature and your social security number. Providing your social security number is voluntary, but you cannot receive CEU credit without it. If you do provide your social security number, this information will be controlled in accordance with Privacy Act requirements, and access will be limited to those with a valid need to know. CEUs earned will be indicated on the course completion certificate under the course title. To receive CEU credit, you will have to attend the entire course (individual decisions as to how much can be missed will be the purview of the NSTC instructor and staff).

CONTACTING THE NSTC
We hope you enjoy this course. If you are interested in any of our other courses, you may contact your center point of contact or the NSTC staff at (281) 244-1284 for additional information. You may also reach us via e-mail at [email protected].
