The Directorate of Enforcement Programs (DEP) provides the OSHA family and the public with guidance on how to comply with the requirements of OSHA standards. DEP provides this guidance in the form of Directives and Interpretations that detail or explain how Compliance Safety and Health Officers (CSHO's) are to enforce OSHA standards and how employers are expected to comply with OSHA standards. DEP provides guidance in the areas of general industry, maritime, whistleblower investigations, federal agencies, and in health areas of the construction industry. OSHA standards covered are 29 CFR Parts 1910, 1915, 1917, 1918, 1919 and portions of 1926 and 1960. DEP monitors Inspection Data and Statistics to identify trends in industry. DEP also works closely with the Directorate of Standards and Guidance and the rest of the OSHA family in the development of new information and ways of protecting workers from safety and health hazards, such as Ergonomic Hazards.
