The purpose of the WHO Manual for the Public Health Management of Chemical Incidents is to provide a comprehensive overview of the principles and roles of public health in the management of chemical incidents and emergencies. While this information is provided for each phase of the emergency cycle, including prevention, planning and preparedness, detection and alert, response and recovery, it is recognized that the management of chemical incidents and emergencies requires a multi-disciplinary and multi-sectoral approach and that the health sector may play an influencing, complementary or a leadership role at various stages of the management process. The target audience includes public health and environmental professionals, as well as any other person involved in the management of chemical incidents.

Please bookmark this page electronically or print a copy of the complete LSM and make it available to laboratory staff. Staff in UW laboratories using hazardous chemicals must have access to a copy of the manual and the supplemental laboratory-specific information.

If a paper copy is preferred, you can print current sections, excerpts or the complete LSM at any UW copy center. Whether you choose paper or electronic, all lab staff must have access the complete chemical hygiene plan while working in the lab.

The information provided in the UC Davis Chemical Hygiene Plan (CHP) (formerly known as the Laboratory Safety Manual) has been compiled from a variety of sources. These include people and organizations within the University of California, as well as external sources. The CHP should be read in conjunction with these references, which provide expanded coverage and more specific applications of health and safety concepts that are treated generally here. Many of the supporting sources are referenced electronically, and as such electronic interaction with the CHP is preferred.

For training purposes, any recent changes to the Chemical Hygiene Plan are tracked in Appendix G. A full list of revisions starting from version 1.0 is available by request from chem-...@ucdavis.edu.

Leading-edge microelectronic processes require very clean process chemicals that are highly filtered and regulated to a particle size of 20 nm or below. With 20 nm particle sensitivity, the Chem 20 Chemical Particle Counter from Particle Measuring Systems (PMS) supports the International Roadmap for Devices and Systems (IRDS) and a large variety of chemicals.

Extensive data on chemical distribution and packaging systems proves that the Chem 20 chemical particle counter, with 20 nm sensitivity, detects larger concentrations of particles with better statistics than competitive products. The Chem 20 Chemical Particle Counter is a valuable tool that enables facility and process engineers to quickly detect and characterize chemical particle sources before they impact process and device performance. Supporting both online and sample based monitoring, the Chem 20 particle counter provides flexible monitoring from incoming QC to point of use.

Academic chemistry laboratories are potentially very dangerous places. Considering the turnover of hundreds of students who must be taught to handle toxic, flammable and explosive compounds often under abnormal conditions of temperature and pressure, it is obvious that there is little margin for error or carelessness even in the undergraduate teaching laboratories. In the research laboratories many operations require pushing the handling of unknown materials or high powered equipment to extreme limits. However, long experience within the discipline of chemistry has proved that, with appropriate foresight and care, almost any kind of a chemical experiment can be carried out without an accident. The keys to safe operations in the chemistry laboratory are:

An additional detailed source, "Prudent Practices in the Laboratory: Handling and Disposal of Chemicals" prepared by the National Research Council can be downloaded as a free PDF from the National Academies Press. This should be made available by the group Safety Officer for ready reference. Also each research group is responsible for developing a Chemical Hygiene Plan. This plan includes but is not limited to an Introduction to the Hazard Communication Standard, the Laboratory Standard, the University Hazardous Waste Policy, A Guide to the Safe Use of Peroxide-Forming Compounds, and laboratory inventory lists of toxic substances and carcinogens. More information about Chemical Hygiene can be found at Duke's OESO website. The present safety manual is a short, ready reference to some of the most common and immediate dangers and also the rules and procedures for reacting to emergencies in this Department. It is not meant to be an exhaustive discussion of laboratory safety.

The safety and well being of its students, faculty, and staff come above all other considerations at Duke University. No experiment that subjects personnel to unreasonable risk is acceptable, no matter how desirable the information which might be obtained. It is the first duty of research directors, instructors, supervisors and all persons in authority to provide for safety in the environment and operations under their control. It is the Chemistry Department's policy to comply not only with legal safety standards, but to act positively, where it can, to prevent injury, ill-health, damage and loss arising from work carried out within its building. The Department seeks to encourage all its members to participate in and contribute to the establishment and observance of safe working practices. This is not only a moral duty, failure to do so can constitute legal grounds for negligence suits. A discussion of Negligence Suits in Chemistry Teaching, J. Chem. Educ. 60, 358 (1983) states, "In all cases it is the teacher who is legally responsible for the safety of his or her students. The teacher must foresee hazards to the extent that any reasonably prudent person would". An aim of this manual and the Duke Chemistry Department safety program is to provide the required information on which to base a prudent approach to safe laboratory operations.

The first responsibility for laboratory safety lies with faculty members (Principle Investigators) in charge of the laboratories. It is their duty to evaluate the safety hazards connected with any experiment and to avoid conducting any experiment which cannot be carried out without excessive risk to personnel or property. It is also the responsibility of the faculty members to be certain that every person working in their laboratories is aware of the safety hazards and safety regulations in the laboratory. It is highly recommended that the person in charge of a laboratory have safety rules posted prominently in convenient locations for everyone to read. Research directors and teaching laboratory directors have the primary responsibility for enforcing regulations on solvent storage, waste solvent disposal, smoking, personal protective equipment, etc., and for reporting problems to the Chemistry Department Safety Committee. Research directors should recognize that graduate students and postdoctoral students coming into the Department may have enormously different backgrounds and attitudes towards good laboratory practice and that it is part of the advisor's responsibilities both in laboratory courses and as research directors to provide instruction where it is necessary either in techniques or in attitudes which are appropriate for the training of professional scientists. It is expected that research directors appoint at least one member of their research groups as a safety officer who will be responsible for maintaining safety devices, attending all monthly safety meetings and checking day-to-day laboratory safety practices. Research directors should have cards fastened to the outside of the door of each laboratory and chemical storage area under his/her supervision which states:

Before any keys to the French Family Science Center can be issued to a new member of the chemistry department, s/he must participate in online safety training and pass the appropriate online quiz(zes). Persons engaged in the use of chemicals and apparatus inside the Department (undergraduate students, graduate student researchers, postdoctoral fellows, etc.) are responsible for protecting themselves and their neighbors. The individual student or researcher has to take the initiative in protecting himself or herself from hazards which have been explained to them, e.g. they should protect their own eyes by wearing safety glasses. Their next responsibility is to their neighbors.

In addition, the Safety Coordinator is available to help members of the Department with individual safety problems. Potential safety problems should be discussed with the safety coordinator. All accidents or near-misses should be reported. This may help to prevent future accidents. See Duke's Occupational & Environmental Safety Office page for information on Chemical Hygiene Plans, SOP information, PHS list and MSDS information.

Chemistry Department policy requires that all persons wear, at least, safety glasses (equipped with side shields), or goggles for eye protection while in the laboratory. In situations in which there is potential of a corrosive chemical being splashed into the eyes, safety glasses or goggles AND a face shield are required. In situations where there is potential for an explosion to occur, head shields are required in addition to safety glasses or goggles. Department policy on contact lenses in the laboratory is that you may wear contact lenses, but only if your eyes are protected as described in the preceding paragraph by safety glasses or goggles, with or without a face or head shield. Normal eye protection is required when you are wearing contact lenses since contact lenses provide little to no protection from chemicals in the eye. (In fact, contact lenses can complicate flooding the eye with water should a chemical get in the eye.) Safety goggles, with side shields are provided for chemistry employees (including all research students and teaching assistants) at no charge. Please see an Undergraduate Lab Manager or the Preparator. Prescription safety glasses are available (at your expense) through a local optometrist. Students who wear prescription glasses, and who do not wish to wear safety goggles (available at Bryan Center Store), must cover the costs involved in being fitted with prescription safety glasses. All undergraduates are expected to purchase and wear safety glasses at all times when they are working at their laboratory benches or in any area where hazardous activities could endanger their eyes. Teaching Assistants and faculty supervising them are expected to enforce this regulation at all times. Teaching Assistants are reminded that the safety performance of classes under their regulation is one of the criteria by which they will be evaluated by the faculty.
