Once you have completed this module, you will need to contact your supervisor or the Learning and Development contact to complete the field training requirement for Confined space rescue.

2.3 Objectives

Notes:

Upon completion of this module you will be able to describe and identify;


· the basic requirements of a rescue plan.

· the responsibilities of the Rescue Team members and the Rescue Team Leader.

· the four basic types of rescues that can be used in horizontal and vertical rescues to remove entrants from confined space, and

· the different types of rescue/retrieval equipment required to perform a confined space rescue.

Full Body Harness training:

in the event the confined space work risk assessment identifies that a full body harness is not required or pose additional hazards to entry personnel due to restricted areas or entanglement hazards, then instruction and training in alternate measures and procedures for use of other extrication devices must be identified in the entry and rescue plans and be incorporated in the Entry Plan specific training.

2.4 Training and Qualifications



Notes:

To get the most out of this training, you must have completed the following training:

Golden Rules

Basic OHS Awareness

Confined Space Awareness

General Confined Space Attendant and Entry training

Notes:


3.2 Introduction

Notes:

Two employees of a company descended into a 35-foot well to repair a pump. Entry was made through a manhole. About six feet below the opening was a plank platform. When the first worker dropped to the platform, he was immediately overcome and fell unconscious into the water below. His partner and another helper entered the well and they too fell unconscious into the water below. A passerby, in an attempt to save the drowning man, jumped into the water and drowned also.

By this time the fire department had arrived. The fire chief, wearing a self-contained breathing apparatus, went to rescue the victims.

On the platform he removed his facemask to give instructions to those above and was overcome. Subsequent tests revealed that the well atmosphere contained a lethal concentration of hydrogen sulphide.


3.3 Introduction

Notes:

As a result of not following proper procedures, such as not performing air quality tests or having a rescue plan and rescue equipment in place prior to entry, five men died in this confined space accident. More than 60% of confined space fatalities are would-be rescuers. That's why it is important to develop a safe and effective rescue plan. Each entry, even on the same confined space, may involve different circumstances. The rescue plan must be reviewed each time. It is imperative that the appropriate rescue response be determined before each entry.

The time taken to figure out a rescue plan after an emergency occurs is time the victim may not have. If the victim has stopped breathing, it is approximately 4 to 6 minutes before brain damage may begin from a lack of oxygen.

3.5 Introduction

Notes:

Employers, or in the case of a project the Constructors are responsible for developing on-site rescue procedures (or plan) before a worker enters a confined space.

The on-site rescue procedure (or plan) is based on the nature of the hazards identified during the confined space work risk-assessment for the task being performed that particular day or shift in each and every confined space, and it will assist in determining how many rescuers are required and where they should be staged. (i.e. at the confined space entrance or in the general area.)


3.6 Introduction

Notes:

Employers, or in the case of a project the Constructors, shall ensure that an adequate number of persons trained and qualified in rescue are available for immediate implementation of the on-site rescue procedures (or plan) based on the confined space work risk assessment.


3.7 Rescue Plan Form

Notes:

The confined space rescue plan form is used as guide in developing adequate written on-site rescue procedures (or plans) for each specific confined space.

This form can be used as the written rescue plan, or

if it is used to develop a specific rescue plan it is to be attached to the on-site written rescue plan and kept on file.



Notes:

The rescue plan form is divided into 4 sections:

It is to be completed as follows:

Section 1

Identify:

the confined space

the Rescue Team Leader.

the known hazards involved in the particular confined space; these could include the exposure to chemical or biological hazards in addition to those listed

This is also your opportunity to ensure any hazards inside the confined space, such as mechanical, electrical or moving parts are correctly isolated.

It is also important to be aware of any external hazards, including those hazards that may be created by the work.



Notes:

The rescue plan form is divided into 4 sections:

Section 1

Determine the configuration of the confined space. The space could be vertical or horizontal. Some spaces are shallow while others may be very deep.

Other confined spaces may have slopes or may contain obstacles that could lead to entanglement problems for both the victim and the rescuer.



Notes:

Section 2

Determine the type and amount of rescue equipment and personal protective equipment to facilitate the rescue.

The equipment to be used will be dependent upon the hazards in the confined space and the relevant plan: examples of safety equipment include full body harness and lifelines, hoist/retrieval systems, SCBA, airline respirators and other PPE.

It is of paramount importance when choosing the equipment to be used in a rescue situation, to take into account the dimensions of the entry / exit points of the confined space, that they be compatible with the dimensions of the rescue equipment and rescue procedures.

If it is decided that breathing air is required to facilitate a rescue, you must ensure that breathing equipment is able to fit through the confined space opening.



Notes:

Section 3

Determine the rescue plan details, identify point of entry, precautions required during the rescue and describe the back-up rescue plan.



Notes:

Section 4

Once enough information is gathered, determine the number of rescue personnel needed.

Rescue personnel must be trained, identified and informed that they have been designated as such prior to each confined space entry.

Rescue personnel must be available as long as there are entry personnel in the confined space.

When an IDLH atmosphere is present, the emergency response team shall be present and ready to respond immediately.

Note: Present and ready to respond immediately means that the emergency response team members specified in the rescue plans are at the confined space, PPE is donned (respirator mask at the ready position), and all controls needed to enter the space immediately are in place. When these conditions are satisfied, the team members should reach the entrant(s) in 3 minutes.


3.13 Rescue Plan Test Form

Notes:

Rescue procedures are to be tested and filed in a central location (preferably in the same location as the entry procedures and plans).

Identify who attended and witnessed the test:

Both printed names and signatures are required at the bottom of the form.

The completed and signed off record of the rescue plan test and a copy of the written rescue plan from Operations or Contractors is to be attached to the confined space entry procedures and scanned and uploaded onto the Mine or Plant intranet drive.

4. The Rescue Team

4.1 Divider

4.2 The Rescue Team

Notes:

The supervisor must ensure that an adequate number of rescue team members


including external service providers:

Are trained in rescue methods, techniques, equipment and standards, Have current knowledge of the Vale Ontario Operations Confined Space Program and Ontario Regulation 632 Confined Spaces Have Entry Plan Specific training and rescue procedures. Have the confined space rescue equipment and PPE as identified in the written on-site rescue procedures. Have First aid and cardiopulmonary resuscitation training. Rescue personnel must also be physically able to perform the rescue procedures as identified in the written on-site rescue plan.

4.3 The Rescue Team

Notes:

Using the safest methods possible, rescue personnel are also responsible for assisting the confined space entry supervisor in developing the rescue plan, training to the required level of proficiency, and testing the plan to ensure adequacy.

The site specific rescue plans/rescue procedures should be practiced as frequently as needed so there is a high level of proficiency.


4.4 The Rescue Team

Notes:

It is important to note that not all members of the rescue team require all elements of rescue training, so long as the rescue team as a whole has adequate training. The amount of training required by each individual member of the rescue team will depend on the particular situation and plan.

(MOL Confined Spaces Guidelines July 2011, section 15, page 50.)


4.5 The Rescue Team

Notes:

It is the responsibility of the rescue team member to verify that the equipment to be used is inspected, ready and in place for immediate implementation.

Equipment inspection records are to be kept and filed.


4.6 The Rescue Team

Notes:

The team member must be ready and available to respond to an emergency immediately when summoned by the attendant.

The team members must not only confirm that all sources of energy have been tagged and locked out as per ZES, they must also add their personal protection locks and tags to the lock box at the start of the job.

The rescue team must keep direct communication with the attendant as determined in the plan.


4.7 The Rescue Team

Notes:

If a member of the team must leave the area established in the plan he must communicate that information to the attendant and the confined space entry supervisor before leaving.

In this case all work will cease and entrants will vacate the confined space until replacement rescuer is found.


4.8 The Rescue Team

Notes:

The rescue team must have an identified rescue team leader with the skills and knowledge needed to direct all aspects of a confined space rescue operation, including the skills and knowledge needed to assess the hazards and develop and implement a rescue plan, and to select applicable equipment and know its limitations.


4.9 The Rescue Team

Notes:

Immediately upon arrival of the scene, the team leader must complete a rapid emergency scene assessment (Size-up) of the existing and potential conditions that may put the rescue team at risk.

Determine by way of a Risk / Benefit Analysis based on the hazards identification and situational assessment that weight the risk to be taken against the benefits to be gained for accepting to manage those risks.

Assume control of all activities during emergency rescue operations, be knowledgeable in all rescue team functions and direct the emergency response team for the overall safety of the rescue operation.


4.10 The Rescue Team

Notes:

Secure any witnesses to the incident and competent persons that know the confined space and work that is being done in it.

Confirm the location of the emergency, the number of entrants and their condition.



Notes:

It is recognized that not all rescues can be performed safety. Certain conditions may exist that would create an unreasonable risk as opposed to a calculated risk to rescuers.

Statement of Confined Space Rescue Entry Policy

The emergency response team will enter a confined space for rescue ONLY if the hazards presented are identified and capable of being effectively mitigated with the resources available.



Notes:

Rescuers should not enter confined spaces containing atmospheres greater than 10% of the LEL (lower explosive limit), regardless of PPE worn (note: there is no adequate protection from an explosion within a confined space).

For elevated LEL situations increase ventilation and exhaust the necessary Cubic Feet Per Minute (CFM) to dilute and lower the LEL, then proceed when at lower than 10% LEL.

The intent of this topic is to not perform hazardous rescue entries, rather to ensure that hazards to rescuers are kept to an absolute minimum.

Completing a Risk / Benefit Analysis concerning the threat to rescuers in relation to the viable victims will determine if the rescue can be safety performed.



Notes:

Limit danger to entanglement to rescuer, (if any entrant is entangled, the rescue team leader must identify the source of energy that caused the entanglement and bring to a Zero Energy State.

Allow for easier retrieval of rescue entrant should this become necessary (provide for clear passage through the opening without removal of necessary PPE, including SCBA.

Assess the scene for the risk of major fire or explosions within a confined space or any other identified risk that would compromise the safety of rescuers.


4.14 The Rescue Team Leader

Notes:

The confined space work risk assessment will assist in determining how many rescuers are required including back-up rescue plan for the entry plan specific rescue procedures and where they are to be staged (i.e. in the general work area or at the confined space entrance.



Notes:

When confined space entry is made into an IDLH atmosphere or one that can quickly develop into an IDLH atmosphere (if ventilation fails or for other reasons) the emergency response team shall be present and ready to respond immediately.

Present and ready to respond means the emergency response team specified in the plans are at the confined space, PPE is donned (respirator mask at the ready position) and all other controls needed to enter the confined space immediately are in place.

When these conditions are satisfied, the team members should be able to reach the entrant(s) in 3 minutes.



Notes:

If the danger to entrants is restricted to mechanical hazards that would cause trauma related injuries ( broken bones, lacerations, abrasions etc.) a response time of 10 to 15 minutes from the time of notification and arrive at the confined space would be adequate, this is in line with the Golden Hour principles for basic trauma life support.

5. Rescue Types

5.1 Divider

5.2 Introduction

Notes:

Four basic types of rescues can be used in horizontal and vertical rescues to


remove entrants from confined space.

They are as follows:

Self-Rescue: Where the entrant is physically and mentally capable of exiting the confined space without assistance and has the foresight to remove themselves from the hazard before it becomes a problem and would require removal.

External Rescue: a process where rescuers do not enter the confined space but a retrieval system is used to extract the entrant.

Entry Rescue: a process where rescuers enter the confined space to retrieve the entrant.

IDLH Entry Rescue: a type of entry where emergency response team has to enter a confined space to rescue an entrant exposed to an IDLH or unknown atmosphere, or to another immediately dangerous condition. Time is of the essence in this situation.

5.3 Entry Rescue


Notes:

There are many situations that require an entry rescue procedure, such as when an entrant has detached their lifeline or there are multiple entrants or there are entanglement hazards.

Another problem requiring rescuers to enter happens when the internal configuration of the confined space prevents simply pulling the worker from the space.

External (non-entry) rescue may not be appropriate or possible for these or other reasons.

Provisions for internal rescue must therefore be part of all rescue plans.

In this situation it must be established that the rescue team can enter the confined space without themselves becoming victims.

5.4 External Rescue

Notes:


If you need to perform an external (non-entry) rescue, you will require the use of retrieval equipment.

Retrieval equipment usually consists of a retrieval line attached to a full-body harness, an anchorage connector and anchor.

The other end of the retrieval line must be attached to a mechanical device or fixed point outside the confined space.

Where a suitable anchor point is not available directly above the confined space entrance, for example an I-beam, the surface around the confined space entrance is used as an anchor.

In this situation a tri-pod can be installed as an anchor.

5.5 IDLH Rescue

Notes:

An IDLH entry rescue is the only rescue scenario where the principle of “Life Over Limb” is allowed.


“Life Over Limb” involves quickly moving a patient without stabilization in situations where there is immediate danger to the patient.

5.6 IDLH Rescue

Notes:

Determining “Life Over Limb” situations is a subjective exercise, but generally involves the following:

An atmosphere that contains contaminants that are of sufficient quantity to cause workers to become disoriented.

An unknown atmosphere with contaminants that could cause respiratory impairment or die;

Fire is present or the likelihood of fire is high;

Explosives are present or there is imminent danger of explosion;


5.7 IDLH Rescue

Notes:

The work area contains hazards (chemical, biological or physical ) other than those specified in items

(a) or (b) that could cause immediately life-threatening injuries (ex: crush injuries, burns, engulfment, or suffocation);

An inability to gain access to workers who need life-saving care; and

An inability to render life-saving care because of an injured worker’s location or position.

In a “Life Over Limb” situation, an injured worker should be moved a reasonable distance from the hazard i.e., out of danger, but no further.

The injured worker should then be stabilized before being moved again.


5.8 Rescue Plan Testing

Notes:

Written On-Site Rescue Procedures are to be in place, have been tested and filed in a central location.

There are 4 types of tests identified in the Confined Space Entry program which includes;

Walk-through test

Simulation test

Parallel test and

Complete test


5.9 Walk‐through Test

Notes:

Walk-through Test

The walk-through test requires that Rescue team members meet to verbally walk through the specific steps of each component of the documented rescue plan.

The purpose of the walk-through test is to confirm the effectiveness of the plan and to identify gaps, bottlenecks, or other weaknesses in the plan.


5.10 Walk‐through Test

Notes:

Walk-through Test

In addition to this the following criteria must be met:

The rescue team must be trained in the use of rescue equipment;

Certification of the rescue equipment must be provided to the project team or plant/mine coordinating entry;

The rescue team must assess the suitability of the rescue equipment listed on the rescue plan;

The equipment listed on the rescue plan must be used for extrication;

Verification by the rescue team that the rescue plan can be executed as written;

A member of the project team or plant coordinating the entry must review the pertinent documentation for completeness, and accuracy prior to the initial entry


into the vessel.

5.11 Simulation Test

Notes:

Simulation Test

Simulation testing requires the rescue team to develop a simulated disaster recreation so normal operations will not be interrupted.

Under this testing technique, the rescue team reviews the plan and identifies key components that should be current and available.

The rescue plan is physically simulated by the rescue team without the use of a manikin.

A checklist can be used to ensure that the team complies with the requirements of the rescue plan.


5.12 Parallel Test

Notes:

Parallel Test

Parallel testing is performed at an alternate site, using a confined space vessel similar in kind.

The physical simulated rescue can be performed with or without the use of a manikin.


5.13 Complete Test

Notes:

Complete Test

The complete test implements all of the requirements of the rescue plan at the confined space vessel using a manikin and all of the rescue equipment listed on the plan.

This test could result in disruption of normal operations. Adequate time must be scheduled for the testing.

The duration of the test should be pre-determined to measure adequate response time.


5.14 Complete Test

Notes:

Complete Test

Various test scenarios could be planned to identify the type of disaster, the extent of damage, recovery capability, staffing, and equipment availability, back-up resources availability, and time/duration of the test.

The test plan should identify the persons responsible and the time they need to perform each activity.

Note:

If the complete test involves an entry rescue activity/exercise then all requirements of this program must be in place prior to the entry portion of the complete test including a rescue plan and rescue personnel to meet the requirements of O.Reg.632-05 Confined Spaces.


5.15 What questions should you ask yourself when determining if the

emergency requires

a “Life Over Limb” rescue?



Correct Choice

X Does the atmosphere contain contaminants that are of sufficient quantity to

cause workers to become disoriented?

X Does the atmosphere contain contaminants that could cause respiratory

impairment or death?

X Is there fire present or, is the likelihood of fire high?

X Are there explosives are present or is there imminent danger of explosion?



Other hazards to be aware of when considering a Life over Limb rescue include, chemical,

biological or physical hazards, the inability to gain access to workers or the inability to render

life‐saving care because of an injured worker’s location or position.
