A guardrail plan requires 28 sections, and 21 sections are installed. How many remain to be installed?
Correct Answer
A) 7 sections.
The remaining sections equal 28 - 21 = 7.
Why This Is the Correct Answer
The remaining sections equal 28 - 21 = 7.
Why the Other Options Are Wrong
Option B: 6 sections.
6 sections. is below the supported result for guardrail tracking; it likely drops a required step.
Option C: 21 sections.
21 sections. is above the supported result for guardrail tracking; it likely adds a step the rule does not support.
Option D: 49 sections.
49 sections. is above the supported result for guardrail tracking; it likely adds a step the rule does not support.
Memory Technique
Spacing and height are guardrails made of measurements for Fall-Protection Corrections.
Reference Hint
Study anchor (closed-book): memorize Guardrail tracking from Cal/OSHA Title 8; CSLB Law and Business Study Guide / Title 8 fall protection guardrail requirements; know the rule or calculation trigger without relying on exam-room lookup.
