NDT Safety Protocols & Compliance Regulations 4

Question 1

API 510 'Pressure Vessel Inspection Code' requires that an Authorized Pressure Vessel Inspector (API) hold which minimum credential?

Accepted Answer

API 510 certification

Answer

API 510 specifically requires that inspectors performing or overseeing code inspections hold a valid API 510 certification.

Question 2

When a boilermaker NDT technician performs ultrasonic thickness testing (UTT) near hot surfaces, what is the maximum metal surface temperature generally acceptable for standard contact transducers without special high-temperature couplants?

Accepted Answer

Approximately 125°F (52°C)

Answer

Standard UT transducers and couplants degrade rapidly above approximately 125°F; high-temperature couplants and delay-line transducers are needed for hotter surfaces.

Question 3

Which regulation requires employers to provide and maintain personal protective equipment (PPE) at no cost to workers performing NDT on boilers?

Accepted Answer

OSHA 29 CFR 1910.132

Answer

OSHA 29 CFR 1910.132 requires employers to assess hazards, provide appropriate PPE, and pay for required PPE at no cost to employees.

Question 4

A boiler has been taken out of service and purged but an oxygen reading of 18% is measured inside. What action is required before entry?

Accepted Answer

Continue ventilation until oxygen reaches 19.5–23.5% and reassess

Answer

OSHA defines oxygen-deficient atmospheres as below 19.5%; continuous ventilation and re-testing are required before safe entry is permitted.

Question 5

What does the 'buddy system' requirement in confined space entry regulations for boiler inspections primarily protect against?

Accepted Answer

Incapacitation of the entrant without a rescuer able to respond

Answer

The buddy/attendant system ensures someone outside the space can monitor the entrant and initiate rescue if the entrant is incapacitated by hazards.
