Connecticut OSHA 10 Certification – Training and State Rules

If someone works on state-funded construction projects in Connecticut, they have likely heard about OSHA 10 Certification. The employer may ask for an “OSHA card,” or it may appear as a requirement on a job application.

Many workers ask:

What does Connecticut actually require?
Is OSHA 10 mandatory in Connecticut?
Can the OSHA training be completed fully online?

Here is what workers need to know about OSHA 10 training, Connecticut laws, and CONN-OSHA enforcement.

What is OSHA 10?

OSHA 10 is a safety training program from the U.S. Occupational Safety and Health Administration (OSHA). The “10” represents the number of training hours.

It is not a formal license for being OSHA certified, but a safety certificate that teaches workers how to stay safe on the job. After completing the course, individuals receive an official OSHA 10 card from the U.S. Department of Labor as proof of training.

Purpose: The goal is to give workers basic knowledge of common workplace hazards and safe practices that help avoid accidents and injuries.

What You Learn: Topics include:

Identifying and preventing fall hazards
Avoiding electrocution
Proper use of personal protective equipment (PPE)
Understanding safety rights on the job
And more

Achievement: Upon completion, individuals receive a printable certificate right away, and the OSHA card is mailed within a few weeks.

Connecticut Law on OSHA 10

Connecticut law (General Statute Section 31-53b) requires all workers on publicly funded construction projects over $100,000 to complete OSHA 10-Hour Construction training.

Main Points:

Who Must Take It:
- Construction laborers and carpenters
- Electricians and plumbers
- Roofers and masons
- HVAC and solar technicians
- Heavy equipment operators and demolition workers
Project Requirement: Publicly funded projects costing $100,000 or more.
Renewal: OSHA 10 cards must be renewed every five years.

Contractors must provide proof that all employees have completed OSHA 10 training within 30 days of starting the project. Workers without a valid OSHA 10 card are not allowed on the job site.

Is OSHA 10 Mandatory in Connecticut?

Yes, but only for some workers.

OSHA 10-Hour Construction training is legally required for employees on state-funded construction projects over $100,000.

For other workers, including:

Private construction employees
Manufacturing Staff
Warehouse and Logistics teams
General Industry workers

OSHA 10 training is not legally required. However, it is strongly recommended. Most employers in Connecticut prefer workers to have OSHA 10 because it:

Helps recognize and avoid workplace hazards
Creates a safer work environment for all
Increases job opportunities and helps career growth
Confirms Compliant with contractor safety standards

In short: OSHA 10 is mandatory for publicly funded projects but strongly recommended for others to improve safety and employment prospects.

The Role of CONN-OSHA

CONN-OSHA, part of the Connecticut Department of Labor, enforces workplace safety and health regulations in the state.

Who They Cover: Workers on state-funded construction projects and other workplaces under the state plan.
What They Do Conduct inspections to verify compliance with OSHA and Connecticut safety requirements, including OSHA 10 training for applicable projects.
Card Requirement: Workers must have a valid OSHA 10 card from a federal OSHA-authorized training provider.
Non-Compliance: Workers without valid training may be removed from the job site, and contractors may face enforcement actions.

While CONN-OSHA enforces state safety rules, the official OSHA 10 card is issued by a federal OSHA-authorized training provider.
