Leading with Safety on projects around the world

Tetra Tech is committed to providing and maintaining a healthy and safe work environment for our employees. Tetra Tech’s program is designed to address the hazards associated with our business and prevent injury and illness in the workplace.

While we work on tens of thousands of projects every year, there’s not a single one of those projects that are more important than every one of our employees going home every day safely. And there’s nothing that’s a higher priority to this company than that.

Dan Batrack, Chief Executive Officer

Tetra Tech intends to meet its responsibilities for health and safety by committing to the following:

  • Complying with applicable standards, laws, and regulations
  • Designating personnel accountable for implementing health and safety programs
  • Communicating health and safety programs and practices throughout the organization
  • Mitigating potential risks through hazard identification and assessment, employee training, and safe work practices
  • Allocating sufficient resources to the program
  • Implementing enforcement and accountability measures
  • Establishing health and safety performance standards

Management is responsible for ensuring that Tetra Tech workplaces are safe and that risks, hazards, and safety violations brought to their attention are investigated and promptly corrected.

Tetra Tech employees are responsible for complying with Tetra Tech’s health and safety policy, programs and standards, and conducting their work safely and without detriment to themselves, other employees, or property. Compliance with health and safety program requirements are mandatory. Willful violation of this policy will be considered cause for disciplinary action up to and including termination.

Establishing a safety culture

Tetra Tech’s safety culture is introduced the moment an employee comes to the company. Employees receive instruction in Tetra Tech’s overarching safety commitment, as well as specific programs and processes relevant to their work. We continue to strengthen and foster this culture of safety through training, mentoring, and ongoing communications.

Providing expert guidance

The team of certified professionals who support our Health & Safety Program includes certified industrial hygienists and safety professionals, mine safety professionals, occupational health specialists, healthcare professionals, and individuals cross-trained in health and safety activities.

Tetra Tech’s enterprise-wide Safety Council includes Health & Safety representatives from each operating unit and provides a regular forum to address safety initiatives, programs, and performance.

Educating our people

Tetra Tech expects employees to participate in developing, implementing, and continually improving our Health & Safety Program. We support our employees by educating and informing them about safety topics of concern, new procedures and guidelines, and available trainings. This support includes:

  • An online Health & Safety library with toolkits, commonly accessed forms, and educational materials
  • Access to free trainings and support for safety-related certifications

Our Focus Four Injury Prevention Program (FOCUS 4)

FOCUS 4 educates employees about the most frequent types of incidents that result in injuries at Tetra Tech’s project sites and offices. FOCUS 4 guidance applies to all operations as a means to address the risk of injury, assess hazard controls, target improvement areas, encourage employee participation, and prevent injuries.
