Which condition would make a confined space 'permit-required' under OSHA 29 CFR 1910.146?
Answer: The space contains or has the potential to contain a serious atmospheric hazard
A confined space becomes permit-required when it contains or may contain a serious hazard such as a hazardous atmosphere, engulfment material, or converging walls.
A safety supervisor is reviewing fire hazard controls in a paint booth. Which control should be prioritized FIRST under the hierarchy of controls?
Answer: Switch to water-based paints to reduce flammable vapor generation
Substituting water-based paints reduces the source of flammable vapors, representing a higher-level engineering control than suppression systems or PPE.
What is the primary purpose of an engineering control such as a machine guard?
Answer: To physically prevent contact between the worker and the hazard
Machine guards physically interpose a barrier between the worker and the point of operation or other hazardous parts, preventing contact.
During a facility walk-through, a safety supervisor identifies a slip hazard from oil on the floor. Which control represents an administrative measure?
Answer: Implementing a housekeeping schedule to clean spills immediately
A housekeeping schedule is an administrative control that relies on worker and management practices to manage the hazard rather than physically changing the environment.
Which term describes a hazard that exists but has not yet been recognized or documented by the employer?
Answer: Latent hazard
A latent hazard is one that is present but undetected, often remaining hidden until a triggering event causes an incident.
A safety supervisor notices workers bypassing a machine's safety interlock. Under the hierarchy of controls, what is the BEST long-term corrective action?
Answer: Redesign the interlock so it cannot be easily bypassed
Redesigning the interlock is an engineering control that removes the ability to bypass the safeguard, providing a more reliable solution than discipline or training alone.
Which element is MOST critical when conducting a baseline hazard assessment of a new facility?
Answer: Walking all work areas and systematically identifying all potential hazards
A comprehensive walk-through of all work areas allows the supervisor to observe conditions firsthand and identify hazards that may not appear in documents or reports.
