zxc Vol 4 Issue #7 July 2012


When you view your chemical inventory report in Chematix, one of the columns you will see is labeled CAS#.  CAS# is an acronym for Chemical Abstracts Service Registry Number.  Every pure chemical has a unique CAS# assigned to it.  This system is extremely helpful when we search for a specific type of chemical, such as chemicals that are listed wastes (P and U-listed).  Or we can use them to search for chemicals that are highly explosive, peroxide formers, chemicals of interest or chemicals on any list such as the Clean Air Act list of hazardous pollutants.

Products are made up of pure chemicals.  There is not a CAS# for a product; instead, it carries as many CAS#s as pure chemicals that make up its composition.  Therefore, Chematix generates a number that begins with a ‘Z’ to hold the place of the CAS#. That Z number is unique to KSU for each product as it is assigned.  If we want to search a specific type of product, we can make a query that will contain the Z number for each product and search in the same manner as the CAS#.

When you need a Material Safety Data Sheet (MSDS) The CAS# and and Z number can be used to search for chemicals in MSDSOnline.

If you have any questions concerning chemicals, CAS#s, Chematix or chemical safety, contact Vanessa Biggers, Chemical Safety Manager, at or ext 2415.

Professional Development Consciousness

The Environmental Health & Safety department continues
to promote professional development consciousness among
employees and others engaged in work for KSU to reduce hazards associated with operations. EHS has achieved a high level of success while working within this framework. Below are areas in which significant contributions and/or recognition have been attained.

  • Stephen Ndiritu passed the Certified Safety Professional (CSP) comprehensive examination (there are only 3 CSPs in the USG).
  • Vanessa Biggers has been elected to serve as Staff Senate President for the 2012-2013 year.
  • Terran Terrell received Safety Certifications including:
    • Defensive Driving Safety Training Certificate
    • Asbestos Certification
    • Incident Command Systems (ICS) Certification through FEMA
  • There is a monthly OSHA approved Fire/Life Safety Training offered at KSU Center.
  • Occupational Safety Training is available for university faculty, staff and student-employees. These trainings include:
    • Asbestos
    • Defensive Driving Course 618 (DDC 618)
    • Coaching the Van Driver
    • Hazard Communication (For Public Employees)
    • Laboratory Safety
    • Bloodborne Pathogen online Training modules (21 in total)

The success of the University’s Environmental Health and Safety efforts depend on all of us. We must work together and accept personal responsibility for our safety and the safety of our colleagues. No job is so important and no service so urgent that we cannot take time to perform our work safely. The spirit of cooperation among all EHS staff members involved in day-to-day operations shows each employee’s commitment to providing the highest level of service to the campus community at large. Retaining engaged and talented employees is an important component in curbing risk. I am proud to be part of such a dynamic group.

If you have any questions regarding safe working conditions or safety trainings please contact our office via email or phone at 770-499-3321.

See you around campus!

Chemicals and their effects on our Health

The Agency for Toxic Substances and Disease Registry (ATSDR) helps protect the Public’s Health through identifying the effects various chemicals have on our health and at what levels these chemicals may be hazardous to our health; this is known as toxicology.  Over 80,000 chemicals are registered for use in the United States.  These chemicals are found in products and processes that we use or utilize each day from household and work place cleaning, hair care, car maintenance, lawn care, prescription drugs, foods, and even personal care.  These products are utilized in preventive/maintenance care and hygiene and can make our lives run easier and cleaner.   However, the way we handle some of these chemicals, the way we use them, and even the way we dispose of them present a hazard to our health and the environment.  If used or disposed of improperly, chemicals can become harmful pollutants in the air, soil, or water.

ATSDR is striving to use various methods to better analyze and understand the specific affects various chemical substances have on our health through using a branch of toxicology know as computational toxicology.  This timely, yet scientifically credible and less expensive, method of toxicology is helping scientists with ATSDR understand more of the health effects and impacts of human exposure for chemicals we know little of.   ATSDR is utilizing advanced, yet efficient methods in research to help achieve their mission and the CDCs mission in protecting the health of the public by providing trusted health information to prevent harmful exposures to toxic substances.  For additional information on this topic please visit the CDC website or contact EHS via email or 770-499-3321.
