Hazardous Chemicals in Schools Achieving Mercury Reductions in Products and Waste 23 May 2005 Kristina L. Meson, USEPA
School Chemicals: In the News “Maine - schools have uncovered stockpiles of potentially dangerous chemicals, including agents used in Chemical Warfare that could cost millions to clean up.” 10/18/04 “Montana – Science teachers across Montana are being surveyed about the chemicals in their classrooms … stockpiles, some perhaps decades old.” 8/31/04 NPR: Safety concerns of school chemistry labs. 1/22/04 EPA - Region 4 responds to Mercury release in school. 4/19/04 Des Moines, Iowa – “Experts hauled out and blew up several containers of unidentified chemicals found in school storage area.” 2/27/04 Tokyo – “School officials failed to dispose of more than 1,000 bottles of radioactive waste.” 8/24/04 Hawaii - “Hazmat crews and police converge on Kalani High School, after students got into a container of sodium cyanide.” 12/12/04
The Big Picture Schools are overburdened, underfunded and understaffed. Environmental health issues usually take a back seat. Stockpiles of chemicals, including mercury, are but one of many environmental and safety issues. Often schools do not have any staff that focus exclusively on environmental or environmental health issues.
Scope of Problem 53 million children and 6 million staff in 118,000 in K-12 schools in US. Chemicals include: –Explosives –Corrosives –Flammables –Toxics –Poisons –Radioactive materials Found throughout the school in science labs, art studios, and maintenance storage facilities.
Why Do We Care About Mercury? Play Video
Why Do We Care About Mercury in Schools? Mercury and children do NOT mix! Neurotoxic, heavy metal that is linked to numerous health effects. Found in products in schools and is often used to demonstrate chemical principles. Most likely route of exposure in schools is inhalation after a spill or while “playing” with elemental mercury. Costly Cleanups and school closures.
EPA Data: The Tip of the Iceberg –In 2004, EPA responded to 12 emergency removals involving mercury. –Data represents a small percentage of incidents since most are handled at the local level and are never reported to national databases.
Case Study 1: Kiln, Mississippi September 2003: Mississippi DEQ requested an emergency response removal at two schools. Mercury Concentrations above EPA levels. Three school buses were contaminated – seats and flooring removed. Children’s clothing tested and some disposed. Total cleanup costs were $200,000.
Case Study 2: Washington, D.C. On October 2, 2003 a student obtained 250 milliliters of liquid elemental mercury from a science laboratory. Contamination spread via several modes of transportation on student shoes and clothing. Breathing zone mercury vapor concentrations were greater than EPA standards. The school was closed for cleanup and reopened after about a month. Eleven homes and one common area were found to be contaminated and about 16 families were displaced for a month. Total cleanup costs were about $1,500,000.
Mercury Legislation 40 states have a partial ban At least 10 states specify a ban on mercury in schools At least 9 states have school mercury cleanout programs
State Hg Reduction Programs New York Dept. of Health –New outreach materials aimed at different school audiences Minnesota – Mercury Free Zone –Clancy the Hg-sniffing dog Wisconsin – Schools Mercury Reduction Program Indiana – Mercury Awareness Program
What Can You do to Reduce the Amount of Mercury in Schools? Help educate students, other teachers and administrators about mercury. Promote proper management and recycling of mercury and mercury-containing products. Eliminate the use of mercury wherever possible at schools. Prevent mercury spills and know what to do if a spill occurs. Promote the use of alternative products that do not contain mercury.

Schools Chemical Cleanout Campaign (SC3) Resource Conservation Challenge project initiated by EPA. Began in April Supports projects across the nation. –10 regional pilots funded in 2004.
Is this your Image of School Chemical Storage?
This is the reality!
Nitric acid, oxidizer and corrosive. Fumes ate through plastic cap then oxidized cardboard box. Extreme fire risk Six pounds of cyanide right above it Earthquake could mean gas chamber for 500 students
Hydrofluoric Acid Anesthetic: acid doesn’t burn on contact Deep tissue and bone disintegration Extreme pain, can cause gangrene, amputation Highly corrosive, dissolves glass Used in Art & Chem classes for glass etching
Goals of the SC 3 Remove outdated, unknown, excessive, or unnecessarily hazardous chemicals from secondary schools; Prevent future stockpiles and reduce accidents by establishing prevention activities such as good purchasing and management practices; Raise national awareness of the problem.
Regional Initiatives All funded programs involved a consortium of partners: –State and Local Department of Environments –School Districts - Administration –Chemical and Waste Management firms Chemicals identified for removal ranged from laboratory to cleaning chemicals. Trained personnel essential for identification and handling of chemicals, and education of school personnel.
What’s Happening in the Field Technical experts make site visits to schools to assess problems. Work closely with school personnel on solutions. Trained personnel remove identified chemicals. Prevention practices implemented (training, purchasing policies, green chemistry, etc.) Follow up.
Creating your own School Cleanout Elements of successful programs include: –On-site technical assistance and school audit; –Teacher and administrator education and awareness-building; –Funding for hazardous chemical disposal; –Additional commitments from school to maintain proper chemical management.
Chemical Management Services Pilot –Public/private partnership with GM/Lansing Public School District (RCC funded). –Team consists of OSW, OPPTS, Region 5, Lansing, MI DEQ. –Chemical Management Services (CMS) and Resource Management (RM) as a combined strategy to improve chemical and waste management in K-12 schools.
RCC Schools Cluster Exploring mutual environmental stewardship approaches for improving school chemical management. Partnerships are essential to success. –Council of State Science Supervisors –General Motors –Association of School Business Officials –National Science Education Leadership Assn –National Science Teachers Assn –Chemical Strategies Partnership (non-profit org) –State and Local governments
State Activities Illinois –School Chemical Collections are mandated. –$800,000 grant just issued Michigan –$200,000 from bottle taxes designated Maine –Two proposals – bond; and pesticide containers

Program History DEP responded to sixteen mercury spills in schools over last three years.DEP responded to sixteen mercury spills in schools over last three years. Spills are costly so it wasSpills are costly so it was decided it was better to go get decided it was better to go get the mercury than to continue responding to spills. responding to spills. After visiting a few schools,After visiting a few schools, program was broadened.
Why did we broaden the program? Wefound a whole host of problems We found a whole host of problems including: including:
This is a middle school. Chemicals stored alphabetically. Curriculum only called for about a dozen of these chemicals. Note acids on far right. This is a middle school. Chemicals stored alphabetically. Curriculum only called for about a dozen of these chemicals. Note acids on far right. Improper Storage
Acids stored in an unlocked metal cabinet designed for flammables. Clips holding shelves were badly corroded. This is after we took most acids out.
Hmmmm.. Methanol. Could tell by smell.
Middle school science room. Gas in unlocked cabinet with unlocked drawer full of matches next to it.
Gas lecture bottles in unlocked drawer of middle school. All highly flammable and/or explosive when exposed to heat, flame or oxidizers. Close to drawer with matches in previous slide.
Lack of knowledge concerning the rules (At least they were not pouring it down the sink!). Most schools follow Flinn disposal methods – Illegal!!!
Historic stockpiles Toxic pesticides and oils in a drawer that hadn’t been opened for 30+ years!
Condition of containers is very poor. All are corrosives. Bottom one is probably sulfuric acid.
Sodium, a flammable, corrosive solid. Should be stored under mineral oil. Water reactive, and forms dangerous hydrogen gas and a solution of corrosive sodium hydroxide.
Calcium Nitrate - strong oxidizer, may explode if shocked or heated. Poor shelf life.
Impure sulfuric acid. Listed for corrosivity and reactivity. Aged – can tell by color.
Sam’s Club effect resulting from spend it or it or lose it monies and limited budgets.A little too much mercuric oxide! Sam’s Club effect resulting from spend it or it or lose it monies and limited budgets. A little too much mercuric oxide! Overstock
Structural limitations of buildings. buildings.Dysfunctional or inadequate equipment
Bromine (9/15/79) and unknown. Bromine is a PIH - Poison Inhalation Hazard, and needs special handling. Expensive to get rid of! Donations These were ‘gifts’ from a college that was closing to several local high schools.
The teacher insisted he was really using this! Note the bottles around it. Should be stored in dedicated base cabinet but wasn’t. Serious eye and respiratory irritant. Human Nature
Nobody we visited was in compliance. So DEP started a Mercury and Chemical Clean-out Program
