District safety guidelines for chemical handling and storage.
District-wide and departmental safety and health committees shall:
- Organize a District-wide safety and health committee to oversee
actions of the departmental safety and health committees.
- A list of approved District-wide chemicals, by sites, will be
- Additions to or removals from the list of approved chemicals are
the responsibility of the District-wide safety and health committee in
conjunction with the department safety and health committees.
- Organize a department safety and health committee for faculty
members, support personnel, and students at each building.
- Have the departmental safety and health committees meet regularly to
discuss safety problems and seek solutions to them.
- Develop a safety and health orientation program for all students and
- Encourage students and staff members to develop concern for their
own safety and for that of others; involve every staff member in some
aspect of the safety program and give each one specific
- Keep appropriate material safety data sheets ready and available in
the work areas.
- Consider providing incentives to students and staff personnel for
- Require all staff members to read the appropriate safety manual;
require students to read the school's departmental safety rules and to
sign statements that they have done so and understand the contents; and
keep these statements on file in the departmental offices.
- Conduct periodic, unannounced inspections to identify and correct
hazardous conditions and unsafe practices; and involve students in a
simulated OSHA inspection.
- For grades kindergarten through five (K-5), implement a no-chemical
curriculum using only articles approved through the Food and Drug
Administration (FDA) and in accordance with the Hazard Communication
Standard [29 CFR 1910.1200(5)(ii)(iii).
- For grades six through eight (6-8), implement a chemical curriculum
that minimizes hazardous materials/waste to include inventory of all
regulated chemicals for program implementation. Follow the methodology
of microexperiments as appropriate or experiments that follow the intent
of the District's chemical program.
- For grades nine through twelve (9-12), implement a chemical
curriculum that minimizes hazardous materials/waste to include inventory
of all regulated chemicals for program implementation. Development of
the chemical curriculum will be based upon reducing hazardous
materials/waste in the educational environment or experiments that
follow the intent of the District's chemical program.
Health and safety in the classroom:
- Make learning how to be safe an integral and important part of the
education process. Teachers of laboratory-type classes will provide
safety instruction as it relates to their classrooms. A test will be
administered at the end of the safety unit. The tests and the results
will be kept for a period of five (5) years.
- Forbid working alone in any laboratory or shop; forbid working
without prior knowledge by a staff member.
- Do not allow laboratory experiments to run unattended.
- Develop specific work practices for individual assignments or
experiments, such as those that should be conducted only in a ventilated
fume hood or that involve especially hazardous chemicals. All chemicals
should be treated as hazardous substances.
- Forbid smoking, eating, and drinking in the chemical work storage
areas. Do not allow food to be stored in chemical refrigerators or
- Forbid mouth pipetting and drinking from lab glasses.
- Provide and assign adequate supplies of personal protective
equipment, goggles, face shields, gloves, aprons, lab coats, and shields
(see personal protective equipment guidelines). When possible, hazardous
experiments should be conducted in a ventilated hood. Substances that
are carcinogens or reproductive health hazards and substances that are
immediately and highly hazardous require special handling procedures and
should be stored in a locked and secured cabinet.
- Obtain medical attention (first aid) for anyone who is overexposed
to a hazardous substance and inform a supervisor immediately. If the
victim is transported to an emergency care facility, the hazardous
substance's material safety data sheet should accompany the victim.
- Provide guards on all vacuum pumps and secure all compressed-gas
cylinders; require grounded plugs on all electrical equipment.
- Install master control shutoff valves for gas, water, and
- Discard chipped, cracked, or damaged glassware into an approved
- Require all accidents (incidents) to be reported, evaluated by the
departmental safety committee, and discussed at departmental safety
- Develop plans and conduct drills to address emergencies such as
fire, explosion, poisoning, chemical spill or vapor release, and
- Display the phone numbers of the fire department, police department,
and local ambulance immediately next to every departmental phone.
- Provide an appropriate supply of first aid supplies and instructions
on their proper use.
- Wear assigned protective equipment and clothing. Require the use of
goggles in all work areas where airborne particulates or liquids are
- Prominently label emergency equipment and train students/faculty
members on their use. Provide fire extinguishers, smoke detectors,
safety showers, eyewash facilities, and ventilated hoods in each work or
storage area and test or check monthly. For example, safety shower-flow
should be at least thirty (30) gallons/ minute, eyewash flow should be
at least three (3) gallons/minute for at least fifteen (15) minutes at
approximately twenty-five (25) psi or less, and hood ventilation should
be at least one hundred (100) cfm at working sash height.
Storage and handling:
- Allow only minimum amounts of flammable liquids in each work area.
Store acids and bases separately. Store fuels and oxidizers separately.
- Avoid alphabetical storing of chemicals, as such practice presents
hazards because chemicals that react violently with each other may be
stored in close proximity. Chemicals should be grouped and stored
according to their organic and inorganic compatible families, as
described in the Flinn System; MSDSs should be reviewed for specific
- Maintain a chemical inventory, both District-wide and by sites, to
avoid purchasing unnecessary quantities of chemicals.
- Use warning signs to designate particular hazards. Label all
chemicals to show nature and degree of hazard.
- Require good housekeeping practices in all working areas. Wash
thoroughly when leaving the work area and before eating, drinking, et
- Carry chemicals in trays or racks, not in your hands.
- Assume that any unfamiliar substance is hazardous and that any
mixture is at least as hazardous as its most dangerous component. Do not
mix chemicals with each other or with any substance (even water) without
specific instructions to do so.
- Develop a program for dating stored chemicals and for discarding
them after predetermined maximum periods of storage.
- Provide fireproof cabinets for storage of flammable chemicals. The
NFPA Code requires that safety storage cabinets be used if more than ten
(10) gallons of Class I or Class II liquids are stored per one hundred
(100) square feet of floor area. Provide well-ventilated storage for
- Consult material safety data sheets (MSDSs) for additional chemical
- Store solvent drums in a secured area. Drums must be grounded and
bonded and should have funnels installed for safe pours.
- See that safety cans are leak-tight and automatically relieve
pressure at five (5) psi. They must also have flame-arrester screens in
- Store solvent rags and oily waste temporarily in approved waste
cans. Waste cans should be emptied daily.
- Secure shelving sections to walls or floor to prevent tipping of
entire sections. Shelving should be equipped with lips to prevent
products from rolling off the shelves.
- Keep hazardous substances in a separate, ventilated, identified
area, away from heat and sun.
- Store breakable containers in chemically resistant trays or overwrap
containers. Chemicals should not be stored on the floor except in
approved shipping containers.
- Do not stack materials so they block aisles, exits, fire-fighting
equipment, alarms, or sprinklers. Maintain at least thirty-six (36)
inches between stored materials and sprinkler systems.
- Ventilate the storage area (at least four  changes of air per
hour). Isolate the chemicals storage area from the building ventilation
Spills and disposal:
- Make a top priority of spill prevention and containment. Whenever
possible, secondary containments and drip pans should be used to prevent
chemical spreading and contamination.
- Clean up broken glass and spills immediately. Neutralizing
chemicals, spill kits, dry sand, vermiculite, and other spill-control
materials should be readily available.
- Develop a system for safe and ecologically acceptable disposal of
chemical wastes. It should be made certain that absolutely no regulated
waste chemicals are disposed of through the sewer system or placed with
general refuse that goes to a sanitary landfill.
Laboratory chemical disposal:
- Review federal, state, and local regulations that may apply to
ridding the school of excess and unwanted chemicals. Before selecting
disposal, verify District-wide that no one else needs or uses material
slated for disposal.
- Option A. Share your list of excess materials with other
schools in the system. Assuming some of the chemicals involved are still
useful, perhaps another school can use what you consider excess. Review
inventories with other department chairpersons.
- Option B. Contact the District safety officer for direction
on proper disposal of hazardous materials/waste and use lab packs. The
safety officer may contact the Arizona Department of Environmental
Quality. Discuss disposal with this agency; perhaps they have valuable
suggestions or can make recommendations for disposal.
- Option C. Pay a commercial firm to assist in removing and
recycling these materials. This is an expensive option. Be sure to ask
for references from such a commercial firm. There are reputable and
reliable firms operating all over the United States. Disposal to a waste
site does not remove District responsibility. Only through recycling or
destruction is the District's liability removed. Ensure that the waste
handler is EPA certified; maintain records of materials disposed of and
the names of the agencies used.
