6-09 - Exposure to toxic/poisonous substances in classrooms
 

Prohibit the use of toxic and poisonous substances as part of classroom or vocational education unless there is a clearly documented need that cannot be otherwise met and there are protocols and procedures in place to protect students and staff from toxin exposure. Communicate policies on acceptable and unacceptable substances to students, staff, and families.

   
Rationale
 

Ingestion, inhalation, or other misuse of potentially toxic substances, whether intentional or unintentional, can be prevented. By adopting policies that reduce access, schools and districts can avoid harmful consequences, such as poisoning and burns.

   
Commentary
 

Art, theater, shop, vocational courses, science courses, and other courses that require the use of toxic substances, such as paints, solvents, wood dust, and other chemicals, require ventilation systems that are found within the American Conference of Governmental Industrial Hygienists (ACGIH) (14,15) guidelines. The ACGIH systems, which consider industrial workers' exposures at the "threshold limit value" (TLV), must be designed to meet the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) standard of 1/10 of the TLV or lower (20-22). Inspections should be performed at least annually for expired chemicals and/or damaged containers, which should be removed and disposed of properly.

Ceramic kilns can be used if they are vented sufficiently and only a teacher or other trained adult is potentially exposed to the heat, kiln wash, etc. Ceramic glazes, either leaded or lead-free, and processes or chemicals requiring ventilation should not be used in elementary schools. For older students in classes such as Chemistry, substances should be properly stored and used with supervision. In areas in which students through age eight may have access, potentially toxic substances should be stored in a locked cabinet.

Poison Control and emergency assistance numbers should be clearly posted by all telephones. Poison control and emergency assistance numbers are 800-222-1222 and 911, respectively. Staff and students should be trained in proper response to poisonings and toxic exposures.
