Boston University (BU) is committed to the safe and compliant use of highly hazardous chemicals (HHCs) in the laboratory. This document sets forth procedures and guidelines in place to protect laboratory workers, those supporting laboratories at BU, and students from the health hazards associated with highly hazardous chemical use in the laboratory. This document was developed by the former Chemical Safety Subcommittee (CSS) of the Laboratory Safety Committee (LSCLaboratory Safety Committee) and is reviewed annually with the CHP.
A chemical is considered “highly hazardous” if it has any health, physical or environmental hazards that require additional safety or environmental practices beyond those of a typical laboratory setting (i.e., requiring greater protection for personnel than standard PPE and/or engineering controls can provide), as required by existing regulations or upon review of the hazards by Environmental Health and Safety (EHSEnvironmental Health & Safety), relevant oversight committees, or other institutional entities.
Additional employee protection is required by the Laboratory Standard and BU for work with particularly hazardous substances. Agents defined as highly hazardous include, but are not limited to, select carcinogens, substances with a high degree of acute toxicity, and substances that pose a high degree of physical hazard. As part of the Highly Hazardous Chemicals Program, BU’s HHC List is reviewed at least annually and revised as needed to remove HHCs no longer in use and to add HHCs not previously used. Additional details on the Highly Hazardous Chemicals Program are available online. Please also refer to BU’s Chemical Hygiene Plan (CHP) for pertinent information.
2. Covered Parties
This document applies to every laboratory or related facility at BU that uses or stores highly hazardous chemicals. Questions should be directed to the Laboratory Safety Coordinator, the Principal Investigator (PIPrincipal Investigator View Boston University's policy on...), Research Core Director (RCD) the LSC, or EHS.
3. Defined Terms
- BioRAFT — an information management system developed for tracking research compliance in laboratories at BU.
- Environmentally Hazardous Chemicals — chemicals listed in 40 CFR 261 Subpart D
- Health Hazard — a chemical for which there is statistically significant evidence
based on at least one study conducted in accordance with established scientific
principles that acute or chronic health effects may occur in exposed employees.
The term “health hazard” includes chemicals which are carcinogens, toxic or
highly toxic agents, reproductive toxins, irritants, corrosives, sensitizers,
hepatotoxicants, nephrotoxicants, neurotoxicants, agents which act on the
hematopoietic system, and agents which damage the lungs, skin, eyes, or
- Highly Hazardous Chemical (HHC) – a chemical that has any health, physical or environmental hazards that require additional safety or environmental practices beyond those of a typical laboratory setting (i.e., requiring greater protection for personnel than standard PPE and/or engineering controls can provide), as required by existing regulations or upon review of the hazards by EHS, relevant oversight committees, or other institutional entities
- Chemical Containment Level (CCL) — A containment level designated by Environmental Health and Safety (EHS) that outlines the requisite administrative controls, engineering controls and personal protective equipment to protect personnel from animals that have been treated with potentially hazardous chemicals that are being housed or handled in BUASC spaces.
- Physical Hazard — means a chemical for which there is scientifically valid evidence that it is a combustible liquid, a compressed gas, explosive, flammable, an organic peroxide, an oxidizer, pyrophoric, unstable (reactive) or water-reactive.
- Safety Data Sheet (SDS) — a safety data sheet prepared for a chemical stating specific hazards and properties of that chemical.
- HHC Standard Operating Procedures (SOPs)
- Highly Hazardous Chemical SOP template — a standard operating
procedure template created by Environmental Health & Safety, which describes the general procedures and safety precautions for a specific HHC or groups of HHC with similar properties. The SOP template should be used by a PI to develop a laboratory-specific SOP, if necessary.
- Adopted Highly Hazardous Chemical SOP — a standard operating procedure that is adopted by a lab with no deviation from recommended practices.
- Approved Laboratory-Specific Highly Hazardous Chemical SOP — a standard operating procedure created by a laboratory using the SOP template developed by the LSC, which describes any significant deviation from the recommended practices approved by the LSC.
- Highly Hazardous Chemical SOP template — a standard operating
4. Use of HHC in Research and Teaching Laboratories
While the Chemical Hygiene Plan (CHP) is available to provide guidance on the general use of chemicals, an additional level of guidance is necessary to ensure the safe use of chemicals considered to be highly hazardous. Before beginning work with these chemicals review the LSC SOP templates for HHC classes located on the HHC Program website. These templates include specific information on the hazards, PPE, engineering controls, handling procedures, storage, emergency procedures and reporting, and disposal requirements. If an appropriate template is not available, the PI, RCD or Instructor/Lecturer should contact Environmental Health & Safety for assistance on developing a new SOP.
Standard Operating Procedures
Using the appropriate template, a PI, RCD or Instructor/Lecturer can:
means a chemical for which there is scientifically valid evidence
that it is a combustible liquid, a compressed gas, explosive, flammable, an organic
peroxide, an oxidizer, pyrophoric, unstable (reactive) or water-reactive.
- Adopt an SOP by adding their laboratory information and submitting the SOP to LSC@bu.edu.
- Revise an SOP with deviations from the recommended practices, add their laboratory information and submit the SOP to LSC@bu.edu via email. The email should contain a rationale for the changes.
When SOPs with deviations are received, a primary reviewer is assigned as determined by the LSC Chair in consultation with the CSO. Any suggested edits, comments, or questions will be returned to the PI, RCD or Instructor/Lecturer. Once all edits, questions and concerns have been addressed, the CSO will inform the laboratory that the SOP has been provisionally approved. The LSC will be updated on any approved HHC SOPs and the following scheduled committee meeting by way of the CSO’s report.
The laboratory is responsible for ensuring that their HHC SOP has been approved prior to the use and storage of HHC. All HHC SOPs should be uploaded to the laboratory’s BioRAFT profile by the PI, RCD or Lecturer/Instructor.
All individuals who work in laboratories, whether they handle HHC or not, must be apprised of the hazards associated with chemicals present in their work area. This information must be provided by the PI, RCD or Instructor/Lecturer before initial assignment and before new potential exposure situations. Below are the requirements for developing a plan to work with highly hazardous chemicals:
- The PI, RCD or Instructor/Lecturer is responsible for oversight of laboratory procedures and ongoing assessment of the need for site-specific training before a laboratory worker or student uses a new hazardous chemical or conducts a new potentially hazardous procedure.
- All laboratory workers must complete basic training as required by the CHP.
- All students must participate in laboratory-specific training.
- The PI, RCD or Instructor/Lecturer and EHS will provide laboratory workers with access to both the HHC SOP and the SDS provided by the manufacturer.
- Prior to conducting any work with HHCs, the PI, RCD or Instructor/Lecturer, EHS and/or designee, must provide HHC reagent-specific training to laboratory workers and students detailing the hazards and safety precautions involved with working with the specific HHC. Training will be renewed annually.
- For research laboratories and research cores, all training records should be documented in the laboratory-specific SOP. The completed training record should be uploaded to BioRAFT.
