This post is to share material developed by Oregon OSHA for doing safety
training to Spanish speaking/English language learning workers in the
workplace.  All print material is developed to promote English language
learning, with the English material on a facing page with the
corresponding Spanish material.

There are various modules on different subjects from which employers
can pick and choose, depending on their industry/needs.  Of particular
value, I believe, is the module called "Cultures, Languages & Safety"
which is directed at the employer/manager/supervisor and 'teaches' them
how to effectively deliver the other modules (or any training) to
Spanish speaking workers.

Oregon OSHA also has an extensive bilingual Spanish-English glossary of
health and safety terms and other health/safety materials at
http://www.cbs.state.or.us/osha/espanol.html 

Oregon OSHA welcomes other states/organizations using and adapting
their material.  The link I'm providing will also provide contact info
for Tomás Schwabe, the 'inventor' of the PESO materials.

I'd welcome hearing of any webbased workplace ESOL programs or
resources material, including basic literacy and computer skills
training sites, where adults can 'get on the web' and learn or improve
their skills.  Sites or software in Spanish, Russian and Vietnamese
would be particularly helpful for my state's Job and Career Centers,
particularly if they are created by non-profit or government agencies
(libraries, state or local government, etc.).  Thanks for what anyone
can provide.
