29 CFR 1926.20–21: OSHA Construction Safety Programs and Training

Regulatory citation: 29 CFR 1926.20, General Safety and Health Provisions, and 29 CFR 1926.21, Safety Training and Education (Construction, Subpart C)

What Are OSHA's Construction General Safety and Training Provisions?

Sections 1926.20 and 1926.21 are the foundation of OSHA's construction standards. Section 1926.20 requires employers to run accident prevention programs, inspect job sites through competent persons, take unsafe equipment out of use and allow only qualified workers to run machinery. Section 1926.21 requires employers to train each employee to recognize and avoid unsafe conditions.

These sections are short and general, but OSHA uses them alongside the more specific construction standards. The specific subparts tell you what controls to use. These sections require a program and training system that makes those controls work.

Why These Provisions Matter

Construction sites change quickly and involve many trades. Without regular inspections and basic hazard training, unsafe conditions can go unnoticed until someone is hurt.

Core Obligations

1. Establish and Maintain Safety Programs (1926.20(b)(1))

Employers must initiate and maintain the programs needed to comply with Part 1926. Most employers meet this with a documented safety program that assigns responsibilities, sets site rules and addresses the hazards of the work.

2. Inspect Job Sites Through Competent Persons (1926.20(b)(2))

Programs must provide for frequent and regular inspections of job sites, materials and equipment by competent persons designated by the employer. Section 1926.32(f) defines a competent person as someone capable of identifying existing and predictable hazards in the surroundings or working conditions, who has authorization to take prompt corrective measures to eliminate them.

3. Remove Unsafe Equipment From Use (1926.20(b)(3))

Machinery, tools, materials or equipment that do not comply with Part 1926 must not be used. They must be identified as unsafe by tagging or locking the controls, or physically removed from the work area.

4. Allow Only Qualified Operators (1926.20(b)(4))

Employers may permit only employees qualified by training or experience to operate equipment and machinery.

5. Treat PPE and Training Duties as Owed to Each Employee (1926.20(f))

Where a construction standard requires PPE, the duty is owed to each employee who must use it, and each failure to provide or ensure use may be a separate violation. The same applies to training. Each employee who is not trained as required may be a separate violation.

6. Train Every Employee on Hazards (1926.21(b)(2))

Employers must instruct each employee in the recognition and avoidance of unsafe conditions and in the regulations that apply to their work environment, so they can control or eliminate hazards or other exposure to illness or injury.

7. Give Specific Training for Harmful Substances, Plants and Animals (1926.21(b)(3)–(5))

Employees who handle poisons, caustics and other harmful substances must be instructed on safe handling and use, potential hazards, personal hygiene and protective measures. Where harmful plants or animals are present, exposed employees must be instructed on the hazards, how to avoid injury and the first aid to use. Employees who handle flammable liquids, gases or toxic materials must be instructed on safe handling and made aware of the specific requirements in Subparts D, F and other applicable subparts.

Common Compliance Approaches

Daily and Weekly Site Inspections

Have the designated competent person complete a short daily walk and a more detailed weekly inspection, with findings tracked to closure.

Site Orientation and Toolbox Talks

Give every new worker a site orientation on hazards and rules, then reinforce key topics through short, documented toolbox talks.

Red Tag System

Use a standard tag or lock for damaged tools and equipment, and remove them to a quarantine area until repaired.

Example: Construction Safety Program in Practice

A mid-size general contractor starts a three-story building. Its safety program names the superintendent as the competent person for daily inspections. On the first walk, the superintendent finds a cracked extension cord and a saw with a missing guard, tags both out of service and records the finding. New laborers attend an orientation that covers fall hazards, silica dust, fire ant mounds found on the lot and first aid for stings. Only workers trained by the rental company may operate the telehandler.

Note: Section 1926.20(a) applies the Contract Work Hours and Safety Standards Act requirement that contractors not require workers to work in unsanitary, hazardous or dangerous conditions on covered contracts. Other parts of these sections apply to construction employers generally. State plan states may set stricter rules.

Frequently Asked Questions

Does 1926.21 still cover confined space training?

No. The current text of 1926.21 ends at paragraph (b)(5) and has no confined space paragraph. Confined space training for construction is set out in Subpart AA, 1926.1207.

Does OSHA require a written safety program for construction?

Section 1926.20(b)(1) requires employers to initiate and maintain programs needed to comply with Part 1926. It does not use the word written, but a documented program is the most practical way to show compliance.

How often must the competent person inspect?

The standard requires frequent and regular inspections. It does not set a fixed interval, so frequency should match how quickly site conditions change.
