Course Overview
Built for telecom outside plant technicians, cable splicers, fiber installers and the foremen who put them below grade. This course covers what actually kills people in manholes: the atmosphere you cannot see, the gas that migrates in from someone else’s leak, the power cable cooking its own insulation two feet from your shoulder, and the rescue attempt that turns one victim into two.
This is not a generic confined space course with the word telecom pasted on. Twelve lessons cover the telecom-specific realities: joint-use manholes, duct banks that conduct gas from blocks away, lead-sheathed cable contamination, transite duct, pressurized splice cases, cable pulling, and the pedestal-handhole-manhole distinctions that decide what the law requires of your crew.
What You Will Learn
- Recognize why a manhole that has always been fine can kill in under an hour, using OSHA’s documented fatality cases and real gas readings
- Decide which OSHA framework governs a given job: 29 CFR 1926 Subpart AA for construction work, 29 CFR 1910.268 for telecom field work with 1910.146 filling the gaps, and what each one requires
- Classify pedestals, handholes, manholes and vaults correctly, including the partial-body entry grey area
- State the acceptable atmospheric ranges and describe testing top to bottom in the required order with a bump-tested, calibrated meter
- Describe ventilation that works: clean upwind air source, duct to the bottom, running continuously, and the failure modes that poison the hole instead
- Explain the entry permit, the entrant, attendant and entry supervisor roles, and what the telecom rule does and does not require
- Recognize joint-use manhole electrical hazards and the stop-and-back-out signals
- Identify the hazards no gas meter detects: lead dust, asbestos-cement duct, isocyanate compounds, fiber shards, contaminated water
- Describe non-entry retrieval, its real-world limits, and why the attendant never enters
Who Should Take This Course
Telecommunications and structured-cabling field personnel: OSP technicians, cable splicers, fiber optic installers, construction crews placing underground plant, and field supervisors and foremen responsible for manhole and vault entries.
Regulatory Framework
The course teaches the current standards that actually govern telecom manhole work, including how they interact:
- 29 CFR 1910.268(o) - Telecommunications: underground lines (manholes and unvented vaults)
- 29 CFR 1910.146 - Permit-Required Confined Spaces, which fills the gaps 1910.268 does not address
- 29 CFR 1926 Subpart AA (1926.1200 to 1926.1213) - Confined Spaces in Construction, which governs construction-phase work
- OSHA letters of interpretation on how these standards fit together, OSHA SHIB 09-30-2013 on gas monitor testing, and NIOSH Publication 86-110 on rescue fatalities
OSHA does not approve, certify or endorse training providers or courses. This course covers knowledge topics; it does not by itself satisfy any OSHA training requirement.
Course Syllabus
- The Hole That Looked Fine - a documented fatality, the real numbers, and what this course can and cannot do for you
- Which Rule Actually Applies to You - construction vs telecom field work vs the full permit program
- Manhole, Vault, Handhole, or Pedestal - classification, and the breathing-zone rule of thumb
- What Is in the Air and Where It Came From - stratification, migration, H2S, CO, oxygen loss
- The Meter You Trust Your Life To - bump test vs calibration, sensor poisoning, sampling technique
- Ventilation That Actually Works - triggers, placement, the exhaust-plume failure, the dilution trap
- The Permit, the Team, and the Attendant - roles, duties, and what the telecom rule does not give you
- Joint-Use Manholes and the Power Side - manhole events, arc flash honesty, stop signals
- The Lid, the Traffic, and the Opening - cover handling, MUTCD work zones, guarding
- Water, Lead, Asbestos, and Chemicals - the hazards no meter alarms on
- Working Inside the Space - cable pulling, pressurized plant, hot work, housekeeping
- Rescue Without a Second Victim - retrieval, its limits, and arranged rescue
Each lesson includes bespoke safety diagrams, an interactive exercise, and a graded knowledge check. The course closes with a 24-question final assessment (80% to pass, retakes allowed).

Before you buy
The practical questions, answered plainly.
Do I get a certificate?
Yes. When you finish the course and pass the assessment, your certificate of completion is available to download immediately from your dashboard. It carries a verification number.
How long do I have access?
Access to this course does not expire. It is self-paced, so you can start, stop and resume whenever you like, and your progress is saved between sessions.
What if I fail the assessment?
You can retake it. Knowledge checks run through the course and the final assessment draws from a larger question bank, so a retake will not simply repeat the same questions.
Does this replace hands-on training?
This course delivers the knowledge portion. Site-specific procedures, equipment-specific practice and any required practical evaluation remain your employer's responsibility, and the course is explicit about where those lines fall.
How often does this training need repeating?
The recommended refresher cadence for this topic is 1 year. Retraining is also triggered by a change in process or equipment, or by an observed gap in an employee's knowledge.
Can I buy this for my whole crew?
Yes. Choose "My team" on this page to buy seats instead of a single enrolment. You become the team administrator, assign seats from your Team Portal as people join, and volume pricing applies automatically at 5 seats and again at 10.
Frequently Asked Questions
What does the Manhole Entry for Telecom Workers course cover?
It focuses on the hazards of entering telecom manholes and vaults, including atmospheric hazards, water, traffic, and buried utilities. You will learn about atmospheric testing, ventilation, entry procedures, and rescue considerations specific to this work. It aligns with the general OSHA confined space requirements for permit-required spaces.
Who should take manhole entry training?
It is designed for telecommunications technicians, cable and fiber crews, and their supervisors who enter underground manholes and vaults. It also suits those overseeing entry programs for these environments. Basic familiarity with field work is helpful but not required.
Is this a knowledge course or hands-on certification?
This is an online knowledge course covering the required awareness and procedures. Hands-on entry practice, equipment training, and site-specific rescue drills must still be completed with your employer.
Can I purchase multiple seats for my crew?
Yes. OccuPros offers group seats so you can enroll an entire crew under one purchase. This makes it easier to keep team training records consistent.
