Industrial Safety Protocols and Risk Assessment Flashcards

When conducting a Job Hazard Analysis (JHA) before torch operations in a confined space, what is the FIRST step?

Answer: Define the job steps and tasks to be performed

A JHA begins by breaking the job into discrete steps before hazards for each step can be identified and controlled.

Under OSHA 29 CFR 1910.252, a hot work permit must include which of the following?

Answer: The time period for which the permit is valid

Hot work permits must specify the authorized time period so that work is not continued beyond safe, inspected conditions.

A risk matrix is used to prioritize hazards by combining which two factors?

Answer: Likelihood of occurrence and severity of consequence

Risk matrices plot probability against consequence severity to assign a risk level and prioritize corrective actions.

Which hierarchy of controls level is considered MOST effective for reducing torch-related fire hazards?

Answer: Elimination or substitution of the hazard

Elimination removes the hazard entirely, making it the most effective control measure in the hierarchy.

What does a Lockout/Tagout (LOTO) procedure protect against when performing torch work near machinery?

Answer: Unexpected energization or startup of equipment

LOTO ensures machinery cannot be unexpectedly energized, preventing crush, cut, or burn injuries to workers using torches nearby.

If a flammable gas concentration reading is at 25% of the Lower Explosive Limit (LEL) in a work area, what action should be taken?

Answer: Stop all hot work and ventilate the area immediately

Hot work must be stopped and the area ventilated any time the flammable gas concentration reaches or exceeds 10% of the LEL.

Which document provides site-specific emergency response procedures that a torch operator must review before starting work?

Answer: The facility's Emergency Action Plan (EAP)

The Emergency Action Plan outlines evacuation routes, assembly points, and emergency contacts specific to the facility.
