ForewordThe central purposes of this EIA Engineering Bulletin are: a.) to provide interpretation of the language and intent of the BRH Guide for Submission of Information on Lasers and Products Containing Lasers in areas where such interpretation would be helpful to a laser product manufacturer in making required reports to the Bureau of Radiological Health (BRH); and b.) to provide advance information on changes which will be made to the Guide (Reference 5) by BRH. These changes include revision of present language found in the January 1976 Guide as well as expected new language in a revised Guide which will be printed and distributed within the next 30-60 days to the three Bureau of Radiological Health (BRH) mailing lists listed below: 1. Laser Manufacturers (Companies who have submitted Initial Reports) 2. Potential Laser Manufacturers 3. Designated Parties Interested in Laser Manufacturing The BRH staff has reviewed and provided comments on this Bulletin and it is believed that a laser product manufacturer desiring to use this Bulletin in the preparation of required Reports to the BRH in advance of receipt of the BRH revised Guide may do so with a certain amount of confidence. Interpretations and forthcoming revisions to the Guide are discussed in detail in this Bulletin. ?
