I have limited Spanish skills but have found it enough to communicate basic comments if you can point and substitute Spanish equivalent of “this thing” when you don’t know specifics. This worked out Ok for general labor and very basic safety, but I would recommend researching and studying proper language terms for safety discussion and skilled labor practice. Your link looks like a great resource (once I turned off auto translation).

Another language is kindness. Be positive. Have extra (new) work gloves and safety glasses to give out. Little things to break the ice will go a long way.

Someone on LinkedIn posted this link: https://www.osha.gov/complianceassistance/spanish/osha-construction-terms-ensp - seems super useful. Figured I would share here as well
