Before a confined space is entered, an employer is required to have _________

• A. a first aid kit, defibtillator, water, and food
• B. testing, monitering, ventiliation equipment
• C. lighting, barriers, ladders, and PPE
• D. both b and c

Answer: (D)

Before entering a confined space, you must address both atmospheric hazards and physical safety measures. Atmospheric safety comes from testing and monitoring the air for oxygen levels and contaminants, and using ventilation equipment to control or restore a safe atmosphere as work proceeds. Physical safety requires good lighting to see clearly, barriers to control access and protect the area, safe entry/exit means such as ladders, and the appropriate PPE to protect workers. This combination covers the main hazards you’ll face inside a confined space.

A first aid kit, defibrillator, water, and food are important safety considerations on a worksite, but they are not the specific pre-entry requirements for confined-space entry. Hence, the option that includes both atmospheric controls and the physical safety measures best fits what must be in place before entry.
