Which of the following is part of CSOSS safety precautions?

• A. Hazard awareness only, not sufficient.
• B. Lockout/Tagout, proper PPE, power-down procedures, hazard awareness, and following approved CSOSS sequences to prevent unsafe actions.
• C. No safety precautions required.
• D. PPE is optional if the risk is low.

Answer: (B)

The main concept is that CSOSS safety relies on a layered approach that stops unsafe actions by controlling energy and enforcing proper procedures before any work begins. The most complete safety picture includes locking out and tagging out energy sources to prevent unexpected energization, wearing the right PPE to protect against hazards, following power-down procedures to ensure equipment is safely de-energized, maintaining hazard awareness to identify and assess risks, and adhering to approved CSOSS sequences so work steps are performed in the correct order and not bypassed.

This combination is best because it covers both the physical controls (locking out energy, de-energizing equipment, using PPE) and the administrative controls (hazard recognition and following approved procedures) that together reduce the chance of harm or equipment damage. Hazard awareness alone isn’t enough without these controls, and PPE alone or procedures alone won’t fully prevent unsafe actions. Options that claim no safety precautions are required or that PPE is optional based on risk overlook the need for a consistent, approved safety process.
