Trench & Excavation
Oregon OSHA Excavation Safety Training for Competent Persons
Trench & Excavation Safety & OSHA Compliant

Under OSHA 29 CFR 1926 Subpart P and enforced by Oregon OSHA (OAR 437 Construction Rules), employers must designate a competent person to oversee excavation safety and conduct required inspections.
KARM Safety Solutions provides Oregon-focused trench and excavation competent person training, helping contractors stay compliant and protect their crews on real jobsite conditions.
