- This page is written for PF users. There are some differences for PF staff.
 Chemical Safety Management System of KEK (Refer to "Safety Guide for Chemicals")
- Chemicals and hazardous substances are managed from various viewpoints such as fire prevention, health keeping, environments. However in KEK, a united management system is adopted for all the chemicals including hazarsous substances and toxic gases. There is one chief manager (M.Taira) in KEK and a manager for every division. For PF Instrumentation and Experiment division, Y.Kitajima is the manager of chemicals.
- Dr. J.Adachi is assigned as the person responsible for specified material gases for semiconductor.
 What are "Chemicals" ?
- KEK regulation defines "Chemicals and Hazardous Substances" as "harmful materials to human health and environments" together with specified substances by a Japanese law concerning fire and a regulation of government emplyee concerning health and safety. This means that not only chemicals in bottles but also gases, solvents, biological samples, oils etc. are also treated as chemicals.
- At the Photon Factory, toxic and/or flammable gases are called as "Special Gases" to be handled with great care.
 Introduction of samples and/or chemicals to PF
- All the experimental groups must submit a "Declaration of introduction of samples/chemicals into the Photon Factory" through the User Support System at least two weeks prior to each assigned beam time. Please refer to an explanation for application.
- All chemicals of any kind, including biological samples, solvents and gases, should be declared before introduction onto the KEK site. If you do not introduce anything, write "nothing" on the form.
- The experimental hall is an enclosed space. You may not exhaust any chemicals into the hall. If you intend to use harmful materials in the hall, describe how to handle them safe. Another form is necessary when you use toxic and/or flammable gases.
- Submitted form will be examined one or two week prior to your beam time. Further explanation will be asked if necessary.
- [Changed from 2011] Examined form will be sent as an attached pdf file by an e-mail to the spokesperson or the representative. You should print it and post it on the beamline display bourd.
 Storage/Management of Chemicals
- You cannot store chemicals in PF for a longer period than your stay. Everything should be brought back.
- All the samples and chemicals should be managed, not to be stolen or not to be lost, by the persons who brought in. Please ask Unten-Toban if you have to temporally store hazardous substances.
 Chemical Experiments and Waste
 Miscellaneous Safety Measures
- Know chemical and physical properties of substances well.
- Do nothing without understanding.
- Handle harmful materials such as beryllium and lead with great care.
- Working alone is prohibited when you do with harmful materials.
- Use minimum solvents for washing such as alcohol and acetone.
- Let flammable chemicals away with your warm work such as baking and soldering.
