Construction Safety: OSHA Requirements and Common Violations

What OSHA Requires in Construction

OSHA classifies construction as a high-hazard industry. Construction workplaces are regulated under 29 CFR 1926, the Safety and Health Regulations for Construction. These standards cover everything from fall protection and scaffolding to excavation, electrical safety, and personal protective equipment.

Construction employers must comply with these standards and provide workplaces free of recognized hazards under the General Duty Clause of the OSH Act. Workers on construction sites face hazards including falls from rooftops, unguarded machinery, being struck by heavy construction equipment, electrocutions, and exposure to silica dust and asbestos.

The "Focus Four" Construction Hazards

OSHA identifies four categories of hazards that account for the majority of construction worker fatalities. These are commonly referred to as the "Focus Four" (also called the "Fatal Four"):

Fall Protection Requirements

In construction, OSHA requires fall protection at a height of 6 feet above a lower level. This is specified in 29 CFR 1926.501 (Duty to Have Fall Protection).

For comparison, other industries have different trigger heights:

• General industry: 4 feet
• Shipyards: 5 feet
• Longshoring operations: 8 feet

The three primary construction fall protection standards are:

• 1926.501 - Duty to Have Fall Protection
• 1926.502 - Fall Protection Systems Criteria and Practices
• 1926.503 - Training Requirements for Fall Protection

Employers must guard every floor hole into which a worker can accidentally walk, provide guard rails and toe-boards around every elevated open-sided platform, and supply required personal protective equipment at no cost to workers. Fall protection systems include guardrails, safety nets, and personal fall arrest systems (safety harness and line).

Scaffolding Safety

Scaffolding hazards are a significant source of injuries and fatalities on construction sites.

Scaffolding in construction is regulated under 29 CFR 1926.451-454 (Subpart L). These standards cover the design, construction, and use of scaffolds, including requirements for guardrails, platforms, and access.

OSHA Construction Safety Programs

OSHA operates several targeted safety initiatives for the construction industry:

• National Safety Stand-Down to Prevent Falls in Construction - An annual event encouraging employers to pause work and discuss fall hazards with employees.
• Fall Prevention Campaign - A national outreach campaign focused on preventing fall deaths and injuries in construction.
• Trenching and Excavation - Focused enforcement and outreach on trench collapse prevention.
• Communication Towers - Targeted safety initiative for tower construction and maintenance work.
• Highway Work Zones - Safety emphasis for workers in road construction zones.
