Safety Procedures & Compliance Flashcards

Which document establishes the legal tolerance requirements that a CWT must apply when testing commercial weighing devices in the US?

Answer: NIST Handbook 44

NIST Handbook 44 (Specifications, Tolerances, and Other Technical Requirements for Weighing and Measuring Devices) is the primary US standard for commercial device tolerances.

A newly installed hopper scale at a grain elevator shows erratic readings during wind gusts. The primary safety and compliance concern is:

Answer: Wind-induced measurement errors affecting commercial transactions

Wind can introduce force errors in suspended hopper scales, causing inaccurate measurements that affect the integrity of commercial transactions.

When must a service technician re-seal a weighing device after performing repairs?

Answer: After any adjustment or repair that could affect metrological performance

Any adjustment or repair that may affect the accuracy of a commercial device requires re-sealing to maintain the integrity of the device's certification.

A vehicle scale technician notices hydraulic fluid pooling beneath a hydraulic scale platform. The immediate safety action is to:

Answer: Stop testing, barricade the area, and address the hydraulic leak before continuing

Hydraulic fluid creates slip hazards and fire risks; the area must be secured and the leak addressed before safe operations can resume.

Which grounding requirement is most important for preventing static discharge when calibrating a livestock scale?

Answer: The scale frame must be bonded to an earth ground to prevent static buildup

Proper bonding and grounding of the scale frame prevents static discharge that can damage electronics and create shock hazards in dry environments.

What is the minimum safe distance a technician should maintain from the edge of a pit scale pit when it is uncovered and unguarded?

Answer: At least 3 feet with a fall protection system in place if closer

OSHA fall protection standards require maintaining safe distances from unguarded floor openings or using fall protection systems when working near them.

A technician finds that a retail grocery scale's price-computing function gives incorrect totals even though the weight display is accurate. Compliance action requires:

Answer: Condemning the device for all commercial use since it cannot produce accurate transaction totals

A price-computing scale with inaccurate computing functions cannot legally be used in commerce because it produces incorrect transaction totals regardless of weight accuracy.
