The American Society of Agricultural and Biological Engineers (ASABE) has revised its standard on manure storage safety, including ventilation and entry protocols.

The revised standard, ASAE EP470.1, Manure Storage Safety, uses field research on worker safety and proper removal of waste from confined manure storage structures. Additional changes include information on confined space entry with references to a relatively new ASABE safety standard, ANSI/ASABE S607, Ventilating Manure Storages to Reduce Entry Risk.

A copy of the document can be ordered by contacting ASABE headquarters directly at:  A full text, electronic copy of the standard also can be viewed by ASABE members and those with site-license privileges to the ASABE online Technical Library.

ASABE is recognized worldwide as a standards developing organization for food, agricultural, and biological systems, with more than 240 standards currently in publication. Conformance to ASABE standards is voluntary, except where required by state, provincial or other governmental requirements, and the documents are developed by consensus in accordance with procedures approved by the American National Standards Institute. For information on this or any other ASABE standard, contact Scott Cedarquist at ASABE, (269) 932-7031, e-mail
