Which of the following best describes the purpose of posting signage at confined space entries?

• A. To inform personnel of hazards
• B. To decorate the entrance
• C. To record water quality data
• D. To indicate working hours

Answer: (A)

Postings at confined space entries are there to alert workers to the hazards inside and to communicate the rules for entry. The sign tells people that the space is confined and may have dangerous atmospheres or other risks, and that entry requires proper training, a permit, and possibly a standby attendant. This visible notice helps prevent unauthorized or unprepared entry and ensures the right precautions—like atmospheric testing, ventilation, lockout/tagout, and appropriate PPE—are followed before anyone goes inside. Decorations, water-quality records, or working-hour notes don’t address safety or entry requirements, so they aren’t the purpose of the signage.
