Work Permit Types & Scope Flashcards

Which type of work permit is required before performing welding, cutting, or grinding near flammable materials?

Answer: Hot work permit

Hot work permits are required for any task that introduces ignition sources (sparks, flames, heat) into areas where flammable or combustible materials may be present.

A cold work permit is distinguished from a hot work permit because:

Answer: Cold work does not introduce ignition sources and involves only non-sparking, non-flaming activities

Cold work permits cover non-ignition tasks such as mechanical disassembly, painting with non-flammable materials, or structural inspections.

An excavation permit is required when digging to what depth in most US industrial and construction sites per OSHA standards?

Answer: 5 feet or more, or any depth when a worker enters the excavation

OSHA 29 CFR 1926.650 triggers cave-in protection (and typically an excavation permit) for excavations 5 feet or deeper, or any depth where a worker enters.

An electrical work permit (lockout/tagout) is governed primarily by which OSHA standard?

Answer: 29 CFR 1910.147

OSHA 29 CFR 1910.147 (Control of Hazardous Energy) governs lockout/tagout procedures for electrical and other energy isolation.

Which type of permit is required for work on pressurized piping systems that could release hazardous energy?

Answer: Line break permit or pressure release permit

Line break or pressure release permits address the hazards of releasing stored energy (pressure, temperature, hazardous fluids) when opening piping systems.

A radiation work permit (RWP) is required because:

Answer: Work in or near radiation fields requires special controls to limit worker dose to ALARA (As Low As Reasonably Achievable) levels

RWPs identify radiation sources, dose rates, required shielding, dosimetry requirements, and access restrictions to protect workers from radiation exposure.
