# DOMAIN 1: SAFETY, RISK MITIGATION & SITE PREPARATION
## 1.1 Lockout/Tagout (LOTO) Procedures
**Question 1**
A BICSI Installer 1 is preparing to work on a telecommunications closet that contains energized
electrical panels. According to OSHA 1910.147, what is the FIRST step the installer must take
before beginning work?
A) Verify that the equipment is de-energized using a multimeter
B) Apply a lock and tag to the energy-isolating device
C) Identify all energy sources and energy-isolating devices
D) Notify the site supervisor of the intended work
**Correct Answer: C**
,Page 2 of 153
**Rationale:** OSHA 1910.147 requires that the authorized employee first identify all energy
sources and energy-isolating devices before any lockout/tagout procedures can begin.
Identification must precede notification, application of locks, or verification. Without proper
identification, workers cannot know which devices to lock out or what hazards exist. This
foundational step ensures that all potential energy sources are accounted for before proceeding
with the lockout/tagout process.

**Question 2**
According to OSHA 1910.147(e)(3), who is authorized to remove a lockout/tagout device after
work is completed?
A) Any certified installer on the jobsite
B) The site foreman or project manager
C) The person who applied the device, after verification
D) The safety officer on duty
**Correct Answer: C**
**Rationale:** OSHA 1910.147(e)(3) explicitly states that lockout/tagout devices must be
removed only by the authorized person who applied them. This ensures accountability and
prevents premature removal that could expose workers to hazardous energy. While a supervisor
or safety officer may oversee the process, the device must be removed by the individual who
installed it.

**Question 3**
Which of the following BEST describes the primary purpose of a lockout/tagout (LOTO)
program in telecommunications installation?
,Page 3 of 153
A) To prevent unauthorized access to telecommunications equipment
B) To protect workers from the unexpected energization or startup of equipment
C) To secure tools and materials during shift changes
D) To document all maintenance activities performed on site
**Correct Answer: B**
**Rationale:** The primary purpose of LOTO is to protect workers from hazardous energy—
specifically, the unexpected energization, startup, or release of stored energy that could cause
injury. While LOTO may have secondary benefits, its core function is worker safety, not security
or documentation.

**Question 4**
During a LOTO procedure, an installer has applied a lock to a disconnect switch. What
additional requirement must be met for the tagout portion?
A) The tag must be made of metal and permanently attached
B) The tag must be placed on the same isolation point as the lock
C) The tag must include the installer's name, date, and reason for lockout
D) The tag must be removed before the lock is removed
**Correct Answer: C**
**Rationale:** Tags must include the identity of the authorized employee who applied them, the
date of application, and the reason for the lockout. This information provides accountability and
, Page 4 of 153
communication for all workers on site. The tag must be attached at the same isolation point as
the lock.
---
**Question 5**
An installer encounters a piece of equipment that has multiple energy sources (electrical,
pneumatic, and hydraulic). What is the correct approach for LOTO?
A) Lock out only the electrical source, as it is the primary hazard
B) Lock out each energy source with individual locks and tags
C) Notify the manufacturer and wait for instructions
D) Use a single lock on the main disconnect switch
**Correct Answer: B**
**Rationale:** All energy sources must be identified and locked out individually. Each source
presents a potential hazard and must be isolated to ensure worker safety. A single lock on the
main disconnect would not address pneumatic or hydraulic hazards.
---
**Question 6**
What is the minimum training requirement for an installer performing lockout/tagout
procedures?
A) On-the-job training from a senior installer
B) Formal training on the specific LOTO procedures for their workplace
C) A general safety orientation completed upon hiring
