MTech Confined Space Non-Entry Rescue Training

Q: What do you mean by “hands-on”?

Trainees will gain practice utilizing a body harness, tripod or davit system in the classroom environment. In the event a simulated confined space structure is available at the training location, hands-on will additionally involve actual practice lowering and retrieving trainees using a tripod or davit system. Our hands-on training covers the proper use of gas detection equipment: calibration, bump testing, monitor placement, alarm response, and real-time decision-making.

Q. What’s the Difference Between Confined Space Entry Rescue and Non-Entry Rescue? What is a confined space?

Confined space entry occurs when a worker physically enters a space that is not designed for continuous occupancy and may have limited means of entry or exit—such as tanks, pits, vaults, or manholes. These environments can present serious hazards including toxic atmospheres, oxygen deficiency, engulfment, or mechanical risks. Because of this, confined space entry rescue requires strict procedures, permits, monitoring, and a fully trained rescue team on standby.

Non-entry rescue is a method of retrieving a worker from a confined space without sending another person inside. This is typically accomplished using pre-rigged retrieval systems such as tripods, davit systems, winches, and harnesses that allow attendants to safely remove an entrant from outside the space. MTech teaches non-entry rescue.

Q: Why is non-entry rescue important?

Non-entry rescue is considered the safest and preferred rescue method because it eliminates the need to expose additional personnel to the hazards inside the confined space. Historically, many confined space fatalities involve would-be rescuers entering without proper protection. Non-entry rescue helps prevent those secondary incidents.

Q: Is non-entry rescue always possible? What is “entry” rescue?

Non-entry rescue is not always possible. Non-entry rescue requires proper planning, equipment, and setup before entry begins. If conditions or space configurations prevent non-entry retrieval, a trained and properly equipped entry rescue team may be required.  MTech does not provide entry rescue training.

Q: What does MTech’s training focus on?

Our training emphasizes:

  • Hazard recognition and risk assessment
  • Proper setup and use of retrieval systems
  • OSHA-compliant confined space procedures
  • Hands-on non-entry rescue techniques
  • Emergency preparedness and response planning

Q: Who should take this training?

Any personnel involved in confined space work—including entrants, attendants, supervisors, and safety managers—benefit from understanding both entry procedures and non-entry rescue techniques.

Q: Does completing this MTech non-entry training authorize or certify persons to enter a confined space or to act in any capacity to be part of the team assigned to confined space entry on behalf of an employer? 

No. MTech’s training teaches confined space safety awareness involving the hands-on protocol described herein.  Authorizing a person or employee to enter a confined space or to participate as a member of a confined space entry team or safety team can only be determined by an employer after ensuring people have attained the proper skill levels need as evidenced by training, practice and experience.  Put another way, MTech provides knowledge, we do not provide real-life training and practical application which may eventually lead to skill deemed sufficient by an employer to consider an employee qualified to their standard to enter a confined space. Refer to MTech’s document:   Understanding OSHA 1910.146 Training vs. Employer Authorization

Q: Why is air monitor training important?

Working in confined spaces means dealing with hazards you often cannot see or smell. Dangerous atmospheres can develop quickly and without warning, making air monitoring one of the most critical components of any confined space safety program.

Q: What is air monitoring?

Air monitoring is the process of using specialized detection equipment to evaluate the atmosphere inside a confined space—both before entry and continuously during occupancy. These instruments measure key hazards such as:

  • Oxygen levels (too little or too much can be dangerous)
  • Flammable or explosive gases and vapors
  • Toxic contaminants such as hydrogen sulfide or carbon monoxide

Q: Why is air monitoring essential?

Without proper monitoring, workers may unknowingly enter an environment that can cause serious injury or death within minutes. Air monitoring provides real-time data so informed decisions can be made about:

  • Whether it is safe to enter a space
  • What protective equipment is required
  • When conditions have changed and evacuation is necessary

Q: What aspects of air monitoring training does MTech provide?

MTech’s hands-on training ensures your team understands not just how to operate equipment but how to rely on it confidently. Topics include:

  • Interpreting readings and making safe decisions
  • Proper use, calibration, and bump testing of gas detection instruments
  • Pre-entry atmospheric testing and continuous monitoring procedures
  • Understanding alarm setpoints and response actions
  • Sensor limitations, cross-sensitivity, and environmental factors
  • Placement of monitors for accurate readings
