Safety and Chemical Hygiene Plan

Purpose

In an effort to maintain a safe environment for all employees and students,Pittsburgh Public Schools (PPS) is committed to managing chemical safety. This Chemical Hygiene Plan sets forth operating procedures and work policies designed to control chemical hazards. In order to maintain a safe environment, PPS willemploy safe operating procedures, reduce the amount of chemicals purchased, ensure safe storing practices, record keeping, and provide chemical safety training for all science teaching staff.

The Pennsylvania Worker and Community Right to Know Act (PWCRK) of 1984 requires public sector employers (including school districts) to provide information on the Act and take various actions. These actions include completing a hazardous substance survey, maintaining a file of Safety Data Sheets (SDS), labeling all containers of hazardous substances or mixtures, employee rights, and provide an inventory to their employees. This manual will provide the basis for compliance to meet the requirements of the (PWCRK).

Scope

To protect employees and students from health hazards associated with the use of hazardous chemicals. We will accomplishthis through the following:

  • Identifying hazardous chemicals.
  • Developing an outline of responsibilities in the district.
  • Developing safe procedures.
  • Discussing procedures for procurement, distribution, and storage of chemicals.
  • Implementing a plan for monitoring safety equipment and storage areas.
  • Developing a written plan to address accidents involving chemicals.
  • Establishing a chemical hazard training program.
  • Developing a chemical waste disposal program.

Topics

  • Chemical procurement and distribution and storage.
  • Housekeeping, maintenance, and inspections of the stockrooms and laboratories.
  • Personal protective apparel and equipment for teachers and students.
  • Warning signs and container labels to identify hazards.
  • Spill response procedures.
  • Training of all science staff.

Location

  • Principal’s Office
  • Custodian’s Office

Safe Operating Guidelines

Science teachers and the science ITL will work collaboratively to ensure general safety practices are followed.

General Safety Practices

  • Electronic and hardy copies of the SDSwill be maintained and readily accessible to all.

All SDS must be entered into the Flinn's Online Chemventory™, anelectronic data base of SDS for all chemicals at the school and district level. Paper copies of the SDS are to be organized and maintained in the chemical storage area in addition to the custodian’s office.

  • Appropriate personal protective equipment is to be worn to avoid contact with chemicals.
  • Chemical splash goggles must be worn any time chemicals, glassware, or open flame are used in the laboratory.
  • Ensure that all laboratories have chemical spill clean-up kits, fire blankets, and broken glass receptacles.

Laboratory Non-Negotiable

  • The school principal and the science department will be contacted if any accident occurs.
  • In event of an accident (emergency and non-emergency) the teacher completes an accident report before the end of the school day.
  • Emergency telephone numbers shall be posted in the chemical storage area.
  • Discard/recycleall chipped, etched or cracked glassware.
  • Teach students how to use the eyewash station and shower.
  • Appropriate fire extinguishers are readily accessible.
  • Employees and students shall be knowledgeable of evacuation routes.
  • Drinking from lab glassware or other lab vessels is strictly prohibited.
  • Eating or drinking is prohibited in the lab.
  • Cosmetics shall not be applied in laboratories.
  • Any and all chemical containers used to store chemicals including water, even temporarily, must be appropriately labeled.
  • Know the hazards and precautions before using any chemical.
  • Follow proper disposal procedures of all chemicals.
  • All exits, emergency equipment, and master utility controls shall remain clear and unobstructed.
  • Fume hoods must be used for handling all hazards chemicals or chemicals that are likely to generate hazardous airborne contaminants.
  • No chemicals shall be stored in the fume hood.

Chemical Inventory

Flinn's Online Chemventory™ will be used to track the procurement and storage of chemicals. In addition, SDS need to be organized in a binder that is readily available and kept in the chemical storage area, the main office, and the custodian’s office.

Flinn's Online Chemventory™tracking system is required to be used at all schools.Each school must complete a chemical inventory annually. For the 2015-16 school year, a chemical inventory must be completed by September 30, 2015. A copy of the inventory tracking sheet is available in the appendix. Please note that each record represents a SINGLE CONTAINER of a chemical (rather than just the chemical itself).

The following tracking fields are recommended:

  • Chemical name as printed on the container and as it appears on the SDS, if different from that on the container.
  • Molecular formula.
  • Chemical Abstract Service (CAS) registry number.
  • Date received Source (i.e., chemical manufacturer, and if known, supplier).
  • Type of container Hazard classification (for storage, handling, and disposal).
  • Required storage conditions.
  • Room number (for larger institutions with multiple storage locations).
  • Location within the room (i.e., shelf #1, acid cabinet).
  • Expiration or “use by” date.
  • Amount of the chemical in the container.
  • Name of the person who ordered or requested the chemical.

Chemical Procurement Guidelines

Before ordering chemicals:

  • Teachers shall not purchase any chemicals contained on the Substances with Greater Hazardous Nature than Educational Utility. (See Appendix A)
  • Assess all the hazards and physical properties of the chemical using the SDS; evaluate both short and long term risks.
  • Consider the worst case scenario(s) in the event that the substance is mismanaged, spilled, or causes personal injury.
  • Determine whether a safer, less hazardous chemical can be used.
  • Order minimum quantities that are consistent with the rate of use and determine whether lesser amounts of a chemical can be used to conduct the experiment.
  • Order only what will be used within a year or less.
  • Determine whether the appropriate facilities are available for the proper storage of the chemical and the ventilation is sufficient.
  • Determine whether the proper personal protective equipment and safety equipment is on hand for using the chemical.
  • Establish whether the chemical or its end product will require disposal as a hazardous waste.
  • Ensure that the budget will allow for the appropriate and legal disposal of the chemical and/or its end product.
  • Have a mechanism in place to dispose of the chemical and the end products legally and safely.
  • If possible, order reagents in polyethylene bottles or plastic coated glass bottles to minimize breakage, corrosion, and rust.
  • Make sure the hazardous properties of the chemical do not exceed the educational utility. When in doubt don’t purchase the chemical.

Chemical Storage Guidelines

  • All chemicals must be properly labeled at all times.
  • All chemicals must be kept under lock and key.
  • All laboratories must be locked when not in use.
  • Chemicals must be checked out from the Chemical Storage Room by teachers only.
  • An inventory of all chemicals must be conducted annually.
  • When needed, a listing of all expired, excess and unwanted hazardous chemicals must be prepared for proper disposal.
  • Chemical containers must be inspected during the annual inspection for container integrity and proper labeling.
  • Always store flammable materials in a flammable storage cabinet, well away from oxidizers.
  • Do not store combustible materials inside or on top of flammable material storage cabinets.
  • Store corrosive materials in corrosion-resistant containers and cabinets.
  • Store acids and bases separately.
  • Do not store chemicals in a laboratory hood, on bench tops or under sinks. They interfere with the airflow in the hood, are more easily knocked over and could potentially spill into a drain.
  • Do not store flammable chemicals in a regular refrigerator. This could result in an explosion and fire. If flammables must be refrigerated, store them in a designated explosion-proof or flammable material refrigerator.
  • Do not store food in a designated chemical refrigerator.
  • Flammable and volatile chemicals should always be stored tightly capped to keep their vapors from interacting and to reduce the potential for human exposure.
  • Store oxidizing acids, such as nitric acid and perchloric acid separate from other acids.
  • Liquids, corrosive chemicals, and glass containers should not be stored on shelves above eye level. No chemicals be stored above eye level.
  • Store heavier containers at a level that is consistent with its size and anticipated use. For example, five-gallon buckets with handles could be stored on a pallet on the floor, while smaller heavy products should be stored on a shelf at waist height to minimize bending and twisting while lifting, which could lead to back or shoulder strain. Secondary containers or totes should be used to minimize the flow of material in the event of a spill or container leak. The materials should be segregated by hazard category.
  • Do not overcrowd the chemical storage area, which would require you to handle several different containers to reach desired product.

Please Note: Mercury compounds, apparatus and thermometers are PROHIBITEDin all PPS schools. If any such items are found, properly secure them in a container and in a safe location in the chemical storage room. Notify the Science Department immediately to request proper disposal.

Emergency Plans for Spills and/or Accidents

The District will provide a spill kit accessible to eachchemistry and middle gradeslaboratories.This kit includes: 

  • Neutralizing agents for acid spills.
  • Neutralizing agents for alkali spills
  • Spill absorbing materials such as sand, kitty litter, or other spill control materials.
  • Quantities of cleanup materials shall be sufficient for the largest anticipated spill.

Chemical Spills Prevention and Clean-up Guidelines

Administrative Controls

  • Spend time educating students about potential spills and how they will be managed in your specific area or classroom.
  • Avoid purchasing chemicals in bulk-sizes, glass containers, and in excess minimizing the probability of spills.
  • Routinely conduct an inspection of chemical containers and storage locations to identify potential leaks, degraded container conditions, or other deficiencies that can lead to leaks or spills.
  • Prevent negligent student behavior including inattentiveness, carelessness, or general horseplay in lab work areas.
  • Develop a school-base plan that details the prevention, containment, cleanup, and reporting of chemical spills. Response plans must be updated annually. These plans are kept in the main office, science classroom, and the custodian’s office.

Cleanliness & Physical Controls

  • Maintain housekeeping in all areas and avoid clutter.
  • Keep containers closed, except when adding or removing contents.
  • Ensure chemicals are properly stored in appropriately-sized containment during long-term storage and during transport between areas or classrooms.

Chemical Spill Clean–Up

  • Inform the students of the hazards of the chemicals stored and used in a particular work area or classroom.
  • Ensure that students understand how to protect themselves andtheir peers during when using chemicals and during a spill.
  • Inform the school nurse of ALL chemical types stored in your laboratory, work area, classroom, and storage closet. Clear communication can ensure that the nurse isprepared to treat any injury that results from a spill. These include broken glass cuts,chemical burns, or extreme temperature exposures (e.g. boiling water or liquid nitrogenexposure).
  • Ensure that appropriate personal protective equipment such as goggles, aprons, and gloves are available for all students handling chemicals, there is an adequate supply, and that students are properly trained on how to use it safely.
  • Ensure that you and your students are ready, equipped, and trained, to manage a spill.

Accident Reporting

The science department will establish and maintain documentation of:

  • Any accidents and incidents involving chemicals.
  • Comprehensive inventory of hazardous chemicals.
  • Annual inspections of storage areas.
  • Annual inspections of general laboratory supplies such as rubber tubing, bunsen burners, hot plates, heat screens etc.)

Chemical Waste Disposal

The science ITL will notify the science department of expired, excess and unwanted hazardous chemicals that need to be disposed. The Science Department will collaborate with the environmental specialist in Facilities Department to have the hazardous chemicals removed.
