Make sure all the safety procedures used in each lab are included. If your lab follows all of the safety procedures given in Part D, you do not have to add information to the Appendix C template. However, Part D should be a complete safety procedure for your lab, so that even new people can learn what they need to know from reading it. If there are additional safety procedures, or criteria to implement exposure control measures, or personal protective equipment used in your lab that is not listed in Part D, you'll have to add information. Further, the OLS focuses on controlling exposures to toxic chemicals.
Some labs use minute quantities of chemicals, such as in a laser or photolysis laboratory.
You will probably need only to address chemical exposures minimally. Be certain that you do what say. A. Note in your Plan any modifications to referenced procedures. If you use the Appendix C template, it is a good idea to Review Part D carefully. Note that corrosives and oxidizers are particularly injurious to eyes, and that seconds count when seeking treatment.
