Inquiry ScienceInquiry Science

• Inquiry is required by the NCSCOS for Science.

• As more inquiry science is taught the number of safety related lawsuits increases.

• The more students “do” the greater the chance of an accident.

Duties of a teacherDuties of a teacher• Duty of instruction.• Duty of supervision.• Duty to properly maintain facilities and equipment.• Failure to perform any duty may result in a

finding that a teacher and/or administrator within a school system is/are liable for damages and a judgment and award against him/them.

DUTY OF INSTRUCTION includes adequateinstruction before a laboratory activity (preferablyin writing) that:

• Is accurate; is appropriate to the situation, setting, and maturity of the audience; and addresses reasonably foreseeable dangers.

• Identifies and clarifies any specific risk involved, explains proper procedures/techniques to be used, and presents comments concerning appropriate/inappropriate conduct in the lab.

• Teachers who set bad examples by not following proper laboratory procedures may be sued if injury results from students following the teacher’s bad examples.

DUTY OF SUPERVISION includes adequatesupervision as defined by professional, legal, anddistrict guidelines to ensure students behave properly in light of any foreseeable dangers.

• Misbehavior of any type must not be tolerated.• Failure to act or improper action is grounds for

liability.• The greater the degree of danger, the higher the

level of supervision should be.• The younger the age of students or the greater

the degree of inclusion of special population students, the greater the level of supervision should be.

More to remember:More to remember:

• Students must NEVER be left unattended, except in an emergency where the potential harm is greater than the perceived risk to students. Even then, risk should be minimized or responsibility transferred to another authorized person if the situation allows.

DUTY OF MAINTENANCE includes ensuringa safe environment for students and teachers.

• Never use defective equipment for any reason.

• File written reports for maintenance/correction of hazardous conditions or defective equipment with responsible administrators.

• Establish regular inspection schedules and procedures for checking safety and first-aid equipment.

• Follow all safety guidelines concerning proper labeling, storage, and disposal of chemicals.

Keep Records!Keep Records!

• By keeping files of all hazard notifications and maintenance inspections, teacher liability in the event of an accident is minimized in cases where no corrective actions were subsequently made.

Teacher responsibilities in regard to Teacher responsibilities in regard to NegligenceNegligence

• The LEGAL DEFINITION of "negligence" isimportant for every teacher to know. Negligence,as defined by the courts today, is conduct that fallsbelow a standard of care established by law orprofession to protect others from an unreasonablerisk of harm, or the failure to exercise due care. Itshould be noted that in the absence of specificlaws or local policies, the standard of care expectedis set by the profession, e.g., position statementsadopted by the National Science TeachersAssociation.

Chemical ManagementChemical Management

Does your school have a current, accurate Chemical Inventory?

Does your school have a comprehensive Chemical Management Plan? (Required by Jan 07)

Are your MSDS sheets up to Date with your Chemical Inventory?

District Chemical Management Plan is posted on Science Dept. web page.

CASE STUDYCASE STUDY• Ballou High School, Washington DC• On October 2, 2003, the Washington, D.C.'s Fire Department Hazmat Unit responded

to an emergency call unlike any call Ballou High School had ever had to make. What the D.C.'s Hazmat unit found that afternoon proved to be the beginning of a long, exhausting search for, and clean up of, an elemental mercury spill. A student had obtained 250 milliliters of liquid elemental mercury from a science laboratory and had sold some of it to other students. Students had to be dismissed. By the time the D.C. Hazmat Team and the D.C. public health officials arrived, it was too late to contain all the spills; varying amounts of mercury were found in the classrooms, gymnasium, and cafeteria. EPA responded by establishing a mobile command post, measuring mercury air concentrations and noting visual contamination of the science laboratory, cafeteria, gym and administration areas.

• Contamination did not stop at the school. Students unknowingly carried mercury on contaminated shoes and clothing through the streets, onto city and school buses, and into their homes. Eleven homes and one common area were found to be contaminated and about 16 families were displaced for a month. EPA assisted with screening of residences.

• As a result of the spill, Ballou High School was closed for 35 days and over 200 homes were tested for mercury contamination. Total cleanup costs were about $1,500,000.

How to Discard chemicalsHow to Discard chemicals

• Waste chemicals should be boxed and stored by compatible families, and labeled “To be Discarded by Hazardous Waste Team” and stored in a secure and safe place until pick-up. An on-line work order should be initiated and sent to the maintenance department. An email should also be sent to Bill Vaught and cc’d to Rachel Sari at the WSFCS Maintenance Department with the work order number, and a complete inventory of chemicals and their approximate amounts that need to be removed. The email should also include the location of chemicals and the name of a contact person to ensure timely pick-up.

JOHNSTON COUNTY, N.C. — A Smithfield-Selma High School science teacher is out of a job because of a questionable experiment.Tuesday, the school board voted 4-1 not to renew Jeff Ferguson's contract. The school's principal made the request earlier in the day.In November, Ferguson asked students to drink milk until they got sick. Ferguson was suspended with pay, then was allowed back in the classroom.
