Safety & Compliance Standards Flashcards

Which ACI certification program is designed for installers of adhesive anchors in concrete?

Answer: ACI Adhesive Anchor Installer (AAI) certification

The AAI program certifies individuals to install adhesive anchors per ACI 318 requirements.

Who is responsible for verifying that the installer holds a valid AAI certification on a project requiring it?

Answer: The special inspector or building official as part of inspection

Inspection includes verifying installer qualifications required by the code and contract documents.

What should an installer do with the first portion of adhesive dispensed from a new cartridge and mixing nozzle?

Answer: Discard it until the adhesive shows a uniform color

Initial output may be improperly mixed, so MPIIs require discarding it until color is consistent.

An anchor is disturbed or loaded before the full cure time listed in the MPII. What is the compliance concern?

Answer: The bond may be compromised and the anchor may not achieve design strength

Loading or disturbing anchors before full cure can damage the bond.

How should empty adhesive cartridges and partially cured adhesive waste generally be disposed of?

Answer: According to the SDS and local environmental regulations

The SDS disposal section and local rules govern chemical waste disposal.

Which hearing protection threshold triggers OSHA's construction requirement to provide hearing protection?

Answer: When noise exposure exceeds the permissible limit of 90 dBA as an 8-hour TWA

OSHA 1926.52 sets 90 dBA (8-hour TWA) as the permissible noise exposure in construction.

If a substitute adhesive product is proposed that differs from the one specified, what is required?

Answer: Approval from the engineer of record, with evaluation data showing equivalent performance

Substitutions require design professional approval since anchor design depends on product-specific qualification data.
