eTraining’s Confined Space Supervisor course is an 8-hour online training program designed for entry supervisors and workers with supervisory responsibilities for permit-required confined space operations. The course covers OSHA CFR 1910.146, the general industry standard for permit-required confined space safety, and is taken entirely online. It emphasizes the necessary supervisory skills and qualifications needed for safe confined space entry.

OSHA defines a confined space as an area that is large enough and so configured that an employee can bodily enter and perform assigned work, has limited or restricted means for entry or exit, and is not designed for continuous employee occupancy. The course covers the role of a confined space entry supervisor in authorizing entries, verifying permits, ensuring safety precautions are in place, and terminating entry operations when needed.

This comprehensive 8-hour course includes hazard identification and remediation, detailed permit-required confined space topics and sub-topics, supervisor responsibilities, confined space entry training, and supervisor training ensuring compliance with OSHA standards and preparing workers for safety and site-specific protocols. The course is 100% online, fully self-paced, and accessible on desktop, tablet, and mobile devices.

For those students who do not need the 8 hour course, we also offer a 2 hour Confined Space Awareness Course.

This course was very enlightening and it goes well with some of the hazwoper classes I took, as well, I'm looking forward to taking some additional courses you have to offer in the future.

This course was very informative and repetitive where necessary. There was a great balance of information between the supervisor's and the rest of the teams' role in a confined space entry.

Great course full of good practical knowledge. I have been in the fire service for 21 years and really enjoyed this class. The videos helped demonstrate real life examples of confined space problems.

I enjoyed your certification coarse.  It was very informative and the program was well put together.  I wish OSHA was using you for their training programs.

It has been very good to spread your Confined Space Supervisor course over a number of weeks and not to have to take it all at once.  We are working on a project where confined space training will be necessary and your training has helped me in writing up the safety plan for this, and getting the safety gear ready ahead of time.  I live in a rural area and could not have found a class of this equal in the time frame needed.

I just want to let you know that the service I received was excellent.  I had signed up for one of our employee's and needed assistance.  The help I got was very professional and very efficient.  I look forward to working with eTraining again.

Frequently Asked Questions

Everything you need to know about the Confined Space Supervisor Course.

  Confined Space Supervisor training is an 8-hour OSHA-compliant safety program covering CFR 1910.146 for general industry permit-required confined space operations. It provides instruction on the role of the entry supervisor, including hazard identification, permit procedures, atmospheric monitoring, worker protection, emergency response, and supervisor responsibilities. The course covers the knowledge and skills needed to authorize confined space entries, verify safety precautions, and supervise entry operations. Upon completion, participants receive a certificate of completion.
  OSHA CFR 1910.146 requires employers to designate entry supervisors for permit-required confined space operations. Workers who need this training include anyone designated as an entry supervisor who authorizes confined space entries, safety officers responsible for confined space programs, site supervisors overseeing workers entering tanks, vaults, silos, or other permit-required confined spaces, and facility managers responsible for ensuring safe entry procedures. The entry supervisor has critical responsibilities that require specialized training beyond basic confined space awareness.
   The course requires 8 hours of instruction time. Because it is self-paced, most students complete it within one to two weeks. You can complete the training over multiple sessions at your convenience. Progress is saved automatically, so you can stop and resume on the same device at any time.
Confined Space Supervisor training is an 8-hour course designed for entry supervisors who authorize and oversee confined space entries. It covers permit procedures, atmospheric monitoring, supervisor responsibilities, emergency response coordination, and comprehensive safety protocols. Confined Space Awareness training is a 2-hour course designed for workers who need basic knowledge of confined space hazards and entry procedures but do not have supervisory responsibilities. The supervisor course provides the in-depth knowledge necessary to authorize entries and manage confined space operations safely.
  According to OSHA CFR 1910.146, a permit-required confined space (PRCS) is a confined space that has one or more of the following characteristics: contains or has a potential to contain a hazardous atmosphere, contains a material that has the potential for engulfing an entrant, has an internal configuration such that an entrant could be trapped or asphyxiated by inwardly converging walls or by a floor which slopes downward and tapers to a smaller cross-section, or contains any other recognized serious safety or health hazard. Entry into permit-required confined spaces requires a written permit and specific safety procedures.
  The entry supervisor is responsible for knowing the hazards that may be faced during entry including information on the mode, signs or symptoms, and consequences of exposure, verifying that all tests specified by the permit have been conducted and that all procedures and equipment are in place before endorsing the permit and allowing entry, terminating the entry and canceling the permit when entry operations are complete or if unacceptable entry conditions exist, verifying that rescue services are available and that the means for summoning them are operable, and removing unauthorized individuals who enter or attempt to enter the permit space during entry operations. The supervisor must be trained to fulfill these duties.
   Yes. The course includes a comprehensive downloadable forms package with templates and samples you can use immediately to implement a confined space program at your workplace. Materials include a Confined Space Entry Program template, sample Confined Space Entry Permit, sample Training Certificate and Verification, sample Non-permit Confined Space Certificate, Training Checklist for Personnel, Hot Work Permit Program, sample Hot Work Permit, sample After Action Report, and supervisor checklists. These materials help ensure proper recordkeeping in accordance with OSHA regulations.
   You must score at least 70% on the final exam to pass the course. Knowledge check quizzes throughout the 8 parts of the course help prepare you for the final exam but do not count toward your grade. If you do not pass on the first attempt, you can review the material and retake the exam.
   Yes. While taking the Confined Space Supervisor course, you have access to an instructor via email. Any questions you have about the material covered throughout the course can be emailed directly to questions@etraintoday.com and an instructor response is guaranteed within 12 hours. This provides expert support as you progress through the training.

The Spanish version covers identical content, meets the same OSHA CFR 1910.146 requirements, includes the same downloadable forms and materials, and results in the same certificate of completion. The Spanish course also includes instructor access with guaranteed response times.
  The course covers types of confined spaces and definitions, hazards including asphyxiation, chemical and atmospheric hazards, and physical hazards, hazard recognition using NFPA labels, OSHA labels, and Safety Data Sheets, regulations and responsibilities including determining permit-required status, responsibilities of entrants, attendants, supervisors, response personnel, and contractors, written program and permit requirements including PRCS program components, permit preparation, and hot work permits, the NIOSH Pocket Guide and terminology for atmospheric monitoring, safety controls including engineering controls, work practices, personal protective equipment, and air monitoring, welding and hot work procedures including gas welding, arc welding, and fire prevention, and emergency response and training including pre-planning, rescue procedures, and supervisor responsibilities.
