1.3 10-Hour and 30-Hour Construction Curricula & Hour Requirements

10-Hour and 30-Hour Construction Curricula & Hour Requirements

Core Principle: The OSHA Construction Outreach Training Program is structured around two distinct tiers: the 10-Hour Construction Course, targeted at entry-level construction workers, and the 30-Hour Construction Course, designed for supervisory, management, and safety personnel. Each course has rigid, non-negotiable minimum hour allocations divided into Mandatory, Elective, and Optional blocks governed by the OSHA Construction Industry Procedures.

2. 10-Hour Construction Outreach Curriculum Breakdown

The 10-Hour Construction course provides entry-level workers with broad awareness of recognition, avoidance, abatement, and prevention of basic construction safety and health hazards.

Mandatory Topics (6.0 Hours Total)

All authorized trainers must cover every mandatory topic for the minimum specified time:

1. Introduction to OSHA (1.0 Hour):

2. OSHA Focus Four Hazards (4.0 Hours Total):
   • Falls (Minimum 1.5 Hours): Fall hazard identification, duty to have fall protection (1926.501), guardrail specifications, personal fall arrest systems (PFAS), and hole covers.

   • Caught-In or -Between (Minimum 0.5 Hour): Trench cave-ins, rotating equipment, unguarded machinery/pinch points, and caught between moving equipment and fixed structures.
   • Note on Focus Four Allocation: The four minimums account for 3.0 hours (1.5 + 0.5 + 0.5 + 0.5). The remaining 1.0 hour must be distributed across any of the Focus Four hazard areas based on class needs.
3. Personal Protective and Lifesaving Equipment (PPE) (0.5 Hour Minimum):
   • Head, eye, face, hand, foot, and hearing protection under Subpart E
   • Employer payment rule for PPE (and exceptions such as non-specialty steel-toe boots and prescription safety eyewear)

   • Chemical hazards (solvents, adhesives, carbon monoxide)
   • Physical agents (occupational noise, heat stress, cold stress)
   • Biological hazards and airborne contaminants (respirable crystalline silica, lead, asbestos)

Elective Topics (2.0 Hours Total)

The trainer must select at least two (2) distinct topics from the following list, delivering each for at least 30 minutes:

• Concrete and Masonry Construction (Subpart Q)
• Permit-Required Confined Spaces (Subpart AA)
• Cranes, Derricks, Hoists, Elevators, and Conveyors (Subpart CC)
• Ergonomics
• Excavations (Subpart P)
• Fire Protection and Prevention (Subpart F)
• Materials Handling, Storage, Use, and Disposal (Subpart H)
• Motor Vehicles; Mechanized Equipment and Marine Operations; Rollover Protective Structures and Overhead Protection; and Signs, Signals, and Barricades (Subparts O, W, G)
• Powered Industrial Vehicles
• Safety and Health Programs
• Scaffolds (Subpart L)
• Stairways and Ladders (Subpart X)
• Steel Erection (Subpart R)
• Tools - Hand and Power (Subpart I)
• Welding and Cutting (Subpart J)

Optional Topics (2.0 Hours Total)

• Additional construction safety and health topics, extending mandatory/elective subjects, or addressing site-specific trade hazards.

3. 30-Hour Construction Outreach Curriculum Breakdown

The 30-Hour Construction course is an extensive safety management curriculum designed for supervisory personnel, safety directors, project engineers, and union stewards.

Mandatory Topics (14.0 Hours Total)

1. Introduction to OSHA (1.0 Hour): Scope, statutory rights, standards access, and complaint processes.
2. Managing Safety and Health (2.0 Hours):
   • Injury and illness prevention programs, job-site inspections, accident prevention programs, management commitment and employee involvement, worksite analysis, hazard prevention and control, accident investigations, how to conduct safety meetings, and supervisory communication.
   • Direct vs. indirect costs of accidents, safety culture, and leading vs. lagging indicators.
   • Note: The Foundations for Safety Leadership (FSL) module is not part of this required block. FSL is a named elective topic in the 30-hour outline with a minimum of 2 hours and 30 minutes.
3. OSHA Focus Four Hazards (6.0 Hours Total):
   • Falls (Minimum 1 hour 30 minutes): Detailed fall hazard analysis, fall protection plans, PFAS clearance calculations, rescue planning.
   • Electrocution (Minimum 30 minutes): Assured grounding programs, temporary power, overhead line clearances, Subpart K.
   • Struck-By (Minimum 30 minutes): Rigging safety, crane swing radius, highway work zones (MUTCD).
   • Caught-In or -Between (Minimum 30 minutes): Excavation shielding/shoring, machine guarding, equipment pinch points.
   • Note on Focus Four Allocation: The published minimums are identical in the 10-hour and the 30-hour class — falls 1.5 hours, the other three 30 minutes each — totalling 3.0 hours. In the 30-hour class the block is 6.0 hours, so the remaining 3.0 hours are distributed across the Focus Four areas at the trainer's discretion. If more than the block time is spent here, the extra may be reported under Focus Four or under a related elective such as scaffolds, cranes, or excavations.
4. Personal Protective and Lifesaving Equipment (PPE) (2.0 Hours Minimum):
   • PPE hazard assessments, selection criteria, maintenance, limitations, and employer payment rules.
5. Health Hazards in Construction (2.0 Hours Minimum):
   • Deep dive into respirable crystalline silica (Table 1 compliance vs. objective data under 1926.1153)
   • Lead in construction (1926.62), occupational noise and hearing conservation (1926.52)
   • Respiratory protection program requirements (1910.134)
6. Stairways and Ladders (1.0 Hour Minimum):
   • Subpart X rules: pitch ratios (4:1), 3-foot extension above landings, ladder duty ratings, proper tie-off, inspection procedures.

Elective Topics (12.0 Hours Total)

• The trainer must choose at least six (6) distinct topics from the official elective list.
• Each elective topic must be taught for a minimum of 30 minutes (0.5 hour), except Foundations for Safety Leadership, which carries its own 2-hour-30-minute minimum.
• The 30-hour elective list is the 10-hour list minus Stairways and Ladders (which is a required topic at this level) plus Foundations for Safety Leadership.
• Electives must be chosen to reflect the specific hazards encountered by the participating workforce.

Optional Topics (4.0 Hours Total)

• Used for specialized industry hazards, company safety manuals, or extending elective modules.

4. The 30-Minute Minimum Topic Duration Rule

A critical rule enforced by OSHA and ATO auditors is the 30-minute minimum duration rule:

• No Micro-Topics: Every topic covered in an Outreach course—whether mandatory, elective, or optional—must be scheduled and taught for a minimum of thirty (30) contiguous minutes (0.5 hour).
• Prohibited Practice: A trainer cannot present a 10-minute overview of scaffolds, a 10-minute overview of excavations, and a 10-minute overview of welding, and combine them into a single 30-minute elective block. Each topic must stand alone with its own measurable learning objectives and substantial instructional content.
• OSHA's Recommendation: Unless otherwise noted, OSHA recommends spending at least one hour on each topic.
• Topic Ceilings (Requirements V.J): A trainer may not spend more than four hours on any single topic in a 10-hour class, or more than six hours on any single topic in a 30-hour class, unless the industry procedures permit otherwise.
• Segments: If the class is broken into segments across days, weeks, or months, each segment must itself be a minimum of 30 minutes and the whole class must finish within 180 calendar days.
