1) IMPORTANT: A printing error has been reported that appears in a limited number of copies of the English version of the ERG2008 books.

Corrections to the ERG2000

A mistake has been found in the english version of the 2000 Emergency Response Guidebook. Please correct the entry on page 360, under the ID No.1162 (first entry on the table). The Guide No. in the guidebook is 151. The correct Guide No. page should be 155 and not 151. This error is only present in the english version of the guidebook. The on-line and download version do not have this error. Please correct in your copy of the guidebook.

A mistake was found in Guide No. 167 for the online and downloadable versions, and not in the printed book. In section for Fire, the heading Small Fire was repeated. The second entry should have read Large Fire. This has been corrected. If you are using the downloadable version, we invite you to please download the new version.
