1 OSHA - Region IV

2 OSHA’s Mission To Assure So Far as Possible Every Working Man and Woman in the Nation Safe and Healthful Working Conditions...

3 OSHA - Region IV Hierarchy of Fall Protection The less human effort for fall protection, the more effective the fall protection EFFECTIVENESS Most Effective Least Effective HUMAN EFFORT Least Effort Most Effort Eliminate Engineered Warning Training PPE

4 OSHA - Region IV Fall Protection - General Requirements Where workers on a construction site are exposed to vertical drops of 6 feet or more, OSHA requires that employers provide conventional fall protection in one of three ways before work begins: –Placing guardrails around the hazard area –Deploying safety nets –Providing personal fall arrest systems for each employee

5 OSHA - Region IV Alternative Procedures Directive STD 3-0.1A - Plain Language Revision of OSHA Instruction STD 3.1, “Interim Fall Protection Compliance Guidelines for Residential Construction” Permits employers engaged in certain residential construction activities to use alternative procedures routinely instead of conventional fall protection

6 OSHA - Region IV Residential Must be engaged in residential construction and performing one of listed activities Not Exempted! –Still obligated to comply with other OSHA standards and conventional fall protection if alternative procedures are not used unsafe practice

7 OSHA - Region IV Residential Construction Working environment, materials, methods and procedures are essentially same as single-family homes or townhouses Characterized by: –Materials: wood framing (not steel or concrete); Wooden floor joists and roof structures –Methods: traditional wood frame construction techniques Discrete part of a large commercial building

8 OSHA - Region IV Listed Activities GROUP 1 - floor joists, floor sheathing, and roof sheathing; erecting exterior walls; setting & bracing roof trusses and rafters GROUP 2 - concrete and block foundation walls and related formwork. GROUP 3 - when performed in attics and on roofs: installing drywall, insulation, HVAC systems, electrical systems (including alarms, telephone lines, and cable TV), plumbing and carpentry GROUP 4 - Roofing work - removal, repair, or installation of weatherproofing roofing materials such as shingles, tile and tar paper
