REPRESENTATIVE SPACES FOR

RESCUE PRACTICE (1910.146 App F)Teams may pracce in representave spaces that are worst case or most

restricve with respect to internal conguraon, elevaon, and portal size.

INTERNAL CONFIGURATION

Open no obstacles, barriers, or obstrucons (ex: water tank)

Obstructed contains obstrucons that a rescuer would have tomaneuver around

ELEVATION

Elevated entrance to opening or portal is above grade by 4 feetor more (usually requires high angle rescue capabilies in packagingand transporng paent to the ground)

NonElevated less than 4 feet above grade

PORTAL SIZE

Restricted portal of 24inches or less (too small for SCBA andnormal spinal immobilizaon)

Unrestricted portal greater than 24inches (allows for relavelyfree movement)

SPACE ACCESS

Horizontal portal is located on side of space (use of retrievallines could be dicult)

Vercal portal is located on top or boom of space (rescuersmust climb up or down to enter; use of special rope techniques orpaent packaging may be required)

OSHAs PermitRequired Conned Space Regulaonrequires employers to provide rescue services whenemployees must enter permit spaces. This checklist

will highlight key rescue compliance points.

EMPLOYER REQUIREMENTS 1910.146 (k)

1. EVALUATE the rescue service:

Ability to respond in a mely manner considering the hazards

idened.Note: OSHAs Respiratory Standard (1910.134) requires standby rescuer(s)capable of immediate acon when making IDLH entries or when IDLHatmospheres could quickly develop.

Prociency with rescuerelated tasks and equipment and abilityto funcon appropriately while rescuing entrants from the types ofspaces idened.

2. SELECT a rescue service that is:

Capable of reaching the vicm(s) within a me frame that isappropriate for hazards idened.

Equipped for and procient in performing the needed rescueservices.

3. FACILITATE the selected rescue service:Inform rescue service of hazards that may be confronted.

Provide access to all permit spaces so that the rescue service candevelop appropriate rescue plans and pracce rescue operaons.

4. PROVIDE for employees assigned rescue dues:

Personal protecve equipment (PPE) and training for use.

Training to perform the assigned rescue dues.

Basic rstaid and CPR training.

Rescue pracce at least once every 12 months, by means ofsimulated rescue operaons from the actual permit spaces or fromrepresentave permit spaces.

Note: Representave spaces shall, with respect to opening size, conguraon,

and accessibility, simulate the types of permit spaces from which rescue is to beperformed.

RESCUE TEAM EVALUATION CRITERIA(NonMandatory Appendix F)

OSHA Note: Nonmandatory Appendix F contains examples of criteria whichemployers can use in evaluang prospecve rescuers as required by paragraph(k)(1). Refer to Appendix F for more details on the required evaluaons.

A. INITIAL EVALUATION

1. Is the rescue service adequately trained and equipped to performpermit space rescues of the kind needed at your facility?

2. Can the rescue service respond in a mely manner?

Note: If an osite service is being considered, the employer must contact the

service to plan and coordinate the evaluaons required by the standard. Merelyposng the services number or planning to rely on 911 would not comply withparagraph (k)(1).

Answering the quesons below will assist employers in determining

whether the rescue service is capable of performing rescues in the

permit spaces at the employers workplace.

What are the needs of the employer regarding rescue responsemes? (me for rescue service to receive nocaon, arrive at scene,setup and be ready for entry)

IDLH (or potenal IDLH) atmospheres require onsite standbyrescue services.

For lesser injuries (broken bones, abrasions), a response me of10 or 15 minutes might be adequate.

How quickly can the rescue team or service get from its locaon torescue scene? (must consider travel me, trac congeson, etc.)

What is the availability of the rescue service? Is it unavailablein certain situaons? Can immediate nocaon be providedto abort the entry?

Does the rescue service meet all requirements of paragraph (k)(2)?If not, how soon? (Ref: #4 in previous checklist.)

For osite services, is the service willing to perform rescues atyour workplace?

Is an adequate (and mely) method of communicaon betweenthe aendant, employer and rescue service available? How soon can

the rescue service be dispatched to the site?

If breathing air equipment is required, does the rescue service havan ample supply? Are procedures in place for rescuers to enter/exit/beretrieved within air supply limits?

If a vercal entry over 5 feet in depth is required, can the rescueservice properly perform entry rescues?

Does the service have the technical knowledge and equipment toperform rope work or elevated rescue?

Does the service have the necessary skills in medical evaluaon,paent packaging and emergency response?

Does the service have the necessary equipment to performrescues, or must the equipment be provided by the employer oranother source?

B. PERFORMANCE EVALUATION

1. Used to measure the rescue performance capabilies of the

service or team and to determine if training/preparedness is

adequate to aect a mely and eecve rescue at the employersfacility.

2. Crique of pracce session can be used to idenfy and correct

deciencies in procedures, equipment, training or number of

personnel.

Are all members trained as permit space entrants (at minimum)including training in potenal hazards of permit spaces, orrepresentave spaces, from which rescue may be needed? Can teammembers recognize signs, symptoms and consequences of exposure?

Is every team member provided and equipped to use theappropriate PPE, such as air equipment (SCBA/SAR) or fall proteconequipment? Is every team member properly trained to performrequired funcons and make rescues? Trained to use any requiredrescue equipment such as ropes and backboards?

Are team members trained in rst aid and medical skills to treatvicms overcome or injured by the types of hazards in the permitspaces on site?

Can all team members perform their funcons safely andeciently? Are rescue personnel trained to focus on their own safetybefore considering the vicm?

If needed, can the rescue service properly test the atmosphere todetermine if IDLH?

Can personnel idenfy pernent informaon such as entry permitshot work permits, and MSDS?

Has the rescue service been informed of any hazards that may arisfrom outside the space?

If needed, can the team properly package and retrieve vicms froma permit space that has a limited size opening (less than 24inches or60.9cm in diameter), limited internal space, or internal obstacles orhazards?

Can the rescue service safely perform an elevated (high angle)rescue?

Does the rescue service have a plan for each of the kinds of permitspaces on site? Is the plan adequate for all types of rescue operaonsthat may be needed?
