A warehouse worker operating a forklift near a marked safety zone, the kind of task behavior-based safety programs observe

Behavior-Based Safety

Behavior-based safety, commonly abbreviated BBS, is a workplace safety approach grounded in behavioral psychology principles that focuses on observing and reinforcing safe work behaviors through structured observation, feedback, and positive reinforcement programs, rather than relying primarily on discipline after an unsafe act or injury has already occurred. The underlying premise of behavior-based safety is that

A Globally Harmonized System hazard pictogram, the kind of standardized label required under the Hazard Communication Standard

Hazard Communication Standard

The Hazard Communication Standard is an Occupational Safety and Health Administration regulation requiring employers to inform and train workers about the hazardous chemicals present in their workplace, often informally called the right to know standard because of its core purpose. Before this standard existed, workers in many industries had limited formal access to information about

Participants practicing witness interview techniques during an accident investigation training course

Incident Investigation

Incident investigation is the systematic process of examining a workplace accident, injury, or near miss to determine its root causes and develop corrective actions that prevent similar events from occurring in the future, rather than simply documenting what happened for administrative purposes. Effective incident investigation deliberately focuses on identifying underlying root causes, such as inadequate

Plant engineers inspecting control equipment, the kind of step-by-step review a job hazard analysis performs

Job Hazard Analysis

A job hazard analysis, commonly abbreviated JHA and also known as a job safety analysis, is a systematic process for identifying the hazards associated with each step of a specific job task and determining appropriate controls to eliminate or reduce those hazards before work begins. Rather than evaluating an entire job as one undifferentiated activity,

An open circuit breaker panel, the kind of electrical energy source isolated during a lockout tagout procedure

Lockout Tagout

Lockout tagout, commonly abbreviated LOTO, is a safety procedure that uses physical locks and warning tags to ensure hazardous machinery is properly shut off and cannot be started up again before maintenance or servicing is complete, protecting workers from unexpected energization or the release of stored energy. Machinery and equipment often contain multiple energy sources,

Factory workers wearing protective masks and goggles, illustrating controls used to keep exposure below a permissible exposure limit

Permissible Exposure Limit

A permissible exposure limit, commonly abbreviated PEL, is the maximum concentration of a hazardous substance that a worker may legally be exposed to in workplace air over a specified period of time, set and enforced by the Occupational Safety and Health Administration for a wide range of industrial chemicals and dusts. Most permissible exposure limits

A construction site, the kind of workplace where a strong safety culture meaningfully shapes everyday safety outcomes

Safety Culture

Safety culture refers to the shared values, attitudes, and behaviors within an organization that shape how seriously workers and management prioritize safety in everyday decisions, extending well beyond what any written safety policy document formally states on paper. An organization might maintain a comprehensive written safety program while still having a weak safety culture, if

Chemical bottles on a laboratory shelf, the kind of hazardous products accompanied by a safety data sheet

Safety Data Sheet

A safety data sheet, commonly abbreviated SDS and formerly known as a material safety data sheet or MSDS, is a standardized document that provides detailed information about the hazards, proper handling, and emergency measures associated with a specific hazardous chemical product. Chemical manufacturers and distributors are required to prepare and provide a safety data sheet

Safety instructors leading a presentation at a safety collaboration group meeting, illustrating a formal safety management system in action

Safety Management System

A safety management system, commonly abbreviated SMS, is a formal, organization-wide framework for systematically managing workplace safety through defined policies, risk assessment processes, and continuous improvement, integrating safety into the overall organizational management structure rather than treating it as a separate, loosely connected set of individual procedures. Rather than relying on a collection of standalone
