BCSP GSP key terms

A condition, source, or act with the potential to cause harm, injury, illness, or property damage. It exists independent of exposure; risk arises only when people or assets contact it.

The combination of the likelihood that a hazard will cause harm and the severity of the harm that could result. Risk is assessed and prioritized so controls target the most consequential exposures first.

A systematic process of identifying hazards, evaluating likelihood and severity of harm, and determining whether existing controls are adequate. Results guide prioritization of corrective actions and resource allocation.

The level of risk that remains after controls have been applied. It must be evaluated against acceptance criteria and communicated to affected workers and management before work proceeds.

A ranked sequence of control strategies from most to least effective: elimination, substitution, engineering controls, administrative controls, and personal protective equipment. Higher-order controls reduce reliance on human behavior.

Physical changes to facilities, equipment, or processes that isolate people from hazards, such as ventilation, machine guarding, interlocks, and noise enclosures. They work without depending on worker behavior.

Policies, procedures, training, scheduling, and work practices that reduce exposure to hazards. They rank below engineering controls because their effectiveness depends on consistent human compliance.

Equipment worn by workers, such as respirators, gloves, hard hats, and hearing protection, to reduce exposure. It is the last line of defense and requires fit testing, training, and maintenance.

Contact between a person and a hazard, described by route, duration, frequency, and intensity. Quantifying exposure is essential to determining whether health effects are likely.

A regulatory occupational exposure limit set by OSHA for airborne contaminants, typically expressed as a time-weighted average, ceiling, or peak concentration. Employers must keep worker exposures at or below these values.

An occupational exposure guideline published by ACGIH, representing airborne concentrations believed safe for most workers over a working lifetime. TLVs are recommendations, not enforceable regulations, but often inform practice.

An exposure metric that averages concentration over a defined period, usually eight hours, to reflect a full shift. It accounts for varying levels of exposure across the workday.

A maximum average concentration permitted for a brief period, typically fifteen minutes, intended to prevent acute effects from short bursts of exposure. It is applied alongside eight-hour limits.

A structured method of breaking a task into steps, identifying hazards at each step, and specifying controls before work begins. It is often used to develop safe work procedures and training content.

A systematic inquiry into an unplanned event to determine contributing factors and root causes, not merely to assign blame. Findings drive corrective actions intended to prevent recurrence.

A technique for tracing an incident back to underlying management-system failures rather than immediate causes alone. Methods include five-why questioning, fault trees, and cause-and-effect diagrams.

An unplanned event that did not result in injury or damage but had the potential to do so. Reporting near misses provides free lessons about weaknesses in controls.

A change made to eliminate the cause of a detected nonconformity or incident and prevent recurrence. Effective corrective actions address system causes and are tracked to completion and verified.

A formal process for reviewing and approving modifications to equipment, processes, materials, or organization before implementation. It ensures that new hazards and impacts on existing controls are evaluated.

A verification conducted before introducing hazardous materials or starting new or modified facilities, confirming that construction, procedures, training, and safety systems meet design intent.

A regulatory framework of fourteen elements, including process hazard analysis and mechanical integrity, aimed at preventing catastrophic releases in facilities handling highly hazardous chemicals.

A space large enough for entry, with limited means of entry or exit, not designed for continuous occupancy. Permit-required spaces add hazards such as engulfment, hazardous atmosphere, or configuration risks.

Measurement of oxygen content, flammability, and toxic contaminants before and during entry into a confined space. Results determine whether entry is permitted and what respiratory protection is required.

A procedure for isolating hazardous energy sources and applying locks and tags before maintenance or servicing. It prevents unexpected energization, startup, or release of stored energy.

Energy forms including electrical, mechanical, hydraulic, pneumatic, chemical, thermal, and gravitational that can injure workers during servicing. Stored energy must be released or restrained before work.

Systems and practices that prevent or arrest falls from elevations, including guardrails, personal fall arrest, and controlled access zones. Selection depends on fall distance, anchorage, and task.

A program of respirator selection, medical evaluation, fit testing, training, and maintenance used to protect workers from airborne hazards when other controls are insufficient.

Requirements to inform workers about chemical hazards through labels, safety data sheets, and training. The goal is that employees understand hazards and protective measures before handling chemicals.

A standardized document providing hazard, handling, storage, and emergency information for a chemical product. It supports hazard communication, risk assessment, and emergency planning.

Measurement of a substance or its metabolite in body fluids or tissues to assess absorbed dose from exposure. It complements air sampling by reflecting actual uptake.

Scheduled health examinations and testing for workers exposed to specific hazards, intended to detect early signs of occupational disease. Results are confidential and may trigger exposure reviews.

A set of requirements triggered when noise exposure reaches an action level, including monitoring, audiometric testing, hearing protection, training, and recordkeeping. Its purpose is preventing occupational hearing loss.

The practice of fitting tasks, tools, and workstations to human capabilities to reduce musculoskeletal strain. It addresses force, posture, repetition, vibration, and recovery time.

The shared values, beliefs, and behaviors that determine how an organization manages safety. It is reflected in reporting willingness, leadership commitment, and learning from errors.

An integrated set of policies, objectives, processes, and responsibilities for managing safety and health performance. It typically follows a plan-do-check-act cycle of continuous improvement.

A proactive measure, such as inspections completed or training hours delivered, that predicts future safety performance. Leading indicators are tracked to prevent incidents rather than react to them.

A retrospective measure of outcomes such as injury rates or lost workdays. It confirms results but offers little warning, so it is paired with proactive measures.

A documented set of procedures describing how occupants respond to fires, releases, medical events, and evacuations. It assigns roles, routes, alarms, and accountability methods.
