LaBrae School District Hydrogen Sulfide Monitoring and Response Plan

   

This plan was created through the cooperation of the LaBrae School District, The Warren Township Fire Department, the Warren Township Fire Department, the Trumbull County Hazardous Materials (HAZMAT) team, the Warren City Fire Department, and ATSDR. This plan is a tailored version of the current response plan the school has in place for other emergencies, as a specific monitoring and response plan to hydrogen sulfide exposures in the area. We hope to find the source and eliminate exposure, but until then, we created this plan to protect students and faculty at the LaBrae District Schools.

Hydrogen sulfide monitors: ATSDR recommended that the LaBrae School District purchase and install hydrogen sulfide monitors equipped with alarms at the three schools closest/within the area of concern identified by ATSDR during a community meeting Tuesday, August 6, 2002. The area to the west (and to the north and south west) of the Warren Recycling, Inc. landfill seemed to represent the majority of residents who had serious health concerns and who noticed odors in outdoor air. This area was selected as the area of concern.

The LaBrae School District purchased three portable hydrogen sulfide monitors (called "Drager PAC III"). A monitor will be located in Leavitt Elementary School, LaBrae High School, and Bascom Elementary School An alarm will sound if a concentration at or above 3 parts of hydrogen sulfide per million parts of air (parts per million or ppm) is detected for 5 minutes or longer.

Where are the monitors going to be located in the school?

The monitors will be located in an area within the school where it will be safe from tampering, where it will reflect indoor exposures, and where the alarm can be heard by a school staff person at all times. This location is most likely the administration office, near an air/circulation vent. The monitor can be moved in case there are reports of odors elsewhere in the school that need to be investigated.

How will the response plan work if the monitor alarm sounds?

If the alarm sounds, a chain of events will begin. The steps of this response plan are listed below:

  • School staff person will contact the Warren Township Fire Department.
  • The on-duty Fire Chief will go the affected school and conduct more thorough indoor/outdoor monitoring using a portable instrument to determine if people should be moved outside (the levels outdoor are lower than indoors), if an evacuation is warranted (the levels outdoors and indoors arc equally elevated), or whether the levels have decreased to a safe level.

Potential responses to indoor/outdoor screening activity:

Situation 1; Levels of hydrogen sulfide are higher inside the schools than they are outside; the Fire Chief will decide to move students to a secure outdoor area (stadium, athletic field, etc.) and continue monitoring indoors until levels are safe. If levels do not gel lower indoors after about an hour or so, remote evacuation (to a distant location) may be ordered.

Situation 2; Levels of hydrogen sulfide are high indoors and outdoors: if levels do not decrease to safe levels during the Fire Chiefs screening activities, he will call a full evacuation of the school. Bus drivers will report to the bus garage at LaBrae High School and drive to the affected school to pick children up and take them to the LaBrae Middle School (5 miles from the impacted area). This evacuation should be completed within 30 minutes of the Fire Chief's orders to evacuate.

** If the Fire Chief decides lo evacuate any of the three schools to a remote area, he will contact the Warren Township Police Chief, the Warren City Fire Chief, and the Trumbull County HAZMAT team to investigate the surrounding community. If levels are unsafe in the community, a community evacuation may also be warranted. The area of evacuation will be determined by these local emergency responders through a perimeter sampling activity.

Situation 3; Levels of hydrogen sulfide decrease to safe levels during the Fire Chief's initial indoor/outdoor monitoring: If hydrogen sulfide decreases to safe levels during the 15-30 minute perimeter investigation, the Fire Chief will not order an evacuation, hut will order that the school day resume as normal.

Estimated Time Line of Evacuation:

Step 1: Chief Schick from the Warren Township Fire Department reported that it would take between 5 and 10 minutes for the Fire Chief to report to any of the three impacted schools after receiving a call, depending on which school calls for assistance.

Steps 2 and 3: The Fire Chief will conduct a brief screening of indoor and outdoor air at the school with a portable hydrogen sulfide meter, to determine what next step should be taken. As a result, he may decide to evacuate to an outdoor location, to a remote location, or not to evacuate. The Fire Chief may take anywhere from 15 to 30 minutes to conduct this screening.

Evacuation Situations:

  • To an outdoor location: moving students to an outdoor location on school property will begin immediately after the order is given.
  • To a remote location: evacuation to a remote location (a full evacuation of the school premises) will depend on the speed that bus drivers can arrive to pick up their buses and load the children. This process will take approximately 30 to 45 minutes.
  • No evacuation: school will resume as normal immediately.

Other situations and contingency plans:

Scenario 1; Teacher notices a strong odor in his/her classroom: The teacher should notify administration as soon as possible. The monitoring device can be carried up to the affected classroom to determine if the levels of hydrogen sulfide in the classroom is unsafe. School administration may choose to activate the Fire Chief in the same manner as the alarm would dictate if it is appropriate.

Scenario 2; During an odor event, a teacher, school nurse, or other staff member gets complaints from several students that they are feeling nauseous, have headaches, their eyes itch or burn, if they vomit, or feel dizzy or tired: The staff member should notify administration as soon as possible. The monitoring device can be carried up to the affected classroom to determine if the level of hydrogen sulfide in the classroom is unsafe. School administration may choose to activate the Fire Chief in the same manner as the alarm would dictate if he/she deems it appropriate.

** EVACUATION MAY BE APPROPRIATE EVEN IF THE ALARM DOES NOT SOUND. DURING AN ODOR EVENT, TEACHERS AND STAFF SHOULD PAY CLOSE ATTENTION TO ANY ABNORMAL BEHAVIORS/ILLNESSES IN STUDENTS AND REPORT ANY CONCERNS TO ADMINISTRATION IMMEDIATELY!!!!!!
