CSP Domain 1: Advanced Application of Safety Principles
Domain 1 is 25% of the CSP, the heaviest of 7 domains by weight. PassCited has 127 questions for it.
BCSP's CSP11 Examination Blueprint, V.2024.04.24 weights Advanced Application of Safety Principles at 25% of the CSP, a 5.5-hour exam. It is one of the two heaviest domains, so it deserves a large share of your study time.

Question 1
A maintenance crew is assigned to clear a jam from a conveyor. The main disconnect on the conveyor is a type that has a hasp and can accept a padlock. The supervisor proposes using only a tag on the disconnect because it is faster. Under the standard, what must the employer's energy control program do?
Show answer and source
Answer: A. Utilize lockout, unless the employer can demonstrate that a tagout system will provide full employee protection
When an energy isolating device can be locked out, the program must use lockout unless the employer can demonstrate that tagout provides full employee protection. Supervisor approval or short duration does not satisfy that requirement.
Answer A rests on
29 CFR 1910.147(c)(2)(ii)(opens ecfr.gov in a new tab)“If an energy isolating device is capable of being locked out, the employer's energy control program under paragraph (c)(1) of this section shall utilize lockout, unless the employer can demonstrate that the utilization of a tagout system will provide full employee protection as set forth in paragraph (c)(3) of this section.”
Question 2
A warehouse has a floor hole beside a conveyor, with the floor 30 inches above the level below. Employees pass near the hole during their normal tasks. Under the standard, what protection is required for this hole?
Show answer and source
Answer: A. Covers or guardrail systems, to protect employees from tripping into or stepping into or through the hole
Holes less than 4 feet above a lower level still require covers or guardrail systems to protect against tripping or stepping into or through them. The distractor claiming no protection is needed misreads the 4-foot threshold, which only changes the type of protection required.
Answer A rests on
29 CFR 1910.28(b)(3)(ii)(opens ecfr.gov in a new tab)“Each employee is protected from tripping into or stepping into or through any hole that is less than 4 feet (1.2 m) above a lower level by covers or guardrail systems.”
Question 3
A maintenance crew is about to service a motor control circuit on a conveyor. The electrician proposes to stop the conveyor with the push-button stop station and the safety interlock on the guard, then begin work without opening the main disconnect, because the controls show the circuit is 'off.' Under the standard, what is the correct response?
Show answer and source
Answer: B. Not acceptable; control circuit devices and interlocks may not be the sole means of deenergizing or substitute for lockout and tagging
The standard bars control circuit devices such as push buttons, selector switches and interlocks from being the sole means of deenergizing, and interlocks cannot replace lockout and tagging. Combining two of these devices still leaves no disconnection from the energy source.
Answer B rests on
29 CFR 1910.333(b)(2)(ii)(B)(opens ecfr.gov in a new tab)“Control circuit devices, such as push buttons, selector switches, and interlocks, may not be used as the sole means for deenergizing circuits or equipment. Interlocks for electric equipment may not be used as a substitute for lockout and tagging procedures.”
