Part 1 appeared in the September 1999 issue.

Winter brings the excitement of winter sports and the wonder of walking on water. Thousands of people worldwide will have adverse incidents on or near the ice, many of which will go practically unnoticed. The ice cracks, and they find themselves immersed in frigid water. Miraculously, they pull themselves out, perhaps with the aid of a friend, and the incident lasts only a few seconds. Embarrassed, they find their way home, warm themselves, dry their clothes, and say thanks.

Sadly, not all ice incidents end so simply. When public safety personnel are dispatched to an ice incident, the statement is already made: The ice is not safe. The victims could not remove themselves, and would-be rescuers may find themselves engulfed by lack of support and frigid water. The fact is, the call would not have been dispatched if the ice were safe.

It is 4:30 in the afternoon. The fading light is about to leave you with very little visibility, and the temperature is dropping. Suddenly, there is an ice rescue call, and you respond. All you need to do is operate on two basic principles: (1) There is only one job you have to do every time–go home, and (2) No ice is safe ice. Any ice on which you perform a rescue can break at anytime, at any place.

A doctorate degree worth of ice physics knowledge means next to nothing during an ice rescue. Safe, practiced procedures; proper equipment; and enough resources are what make the difference between success and death. Assume the ice will break, and be ready when it does.

PREPARATION PHASE

Be proactive. Perform the preparation phase with care and knowledge. Do not be reactive to the incident`s demands. Plan the act, and act the plan. If you started performing the procedures presented in Part 1 of this series, you are well on your way to becoming proactive and complying with sections 2-2 to 2-5.1.2 of National Fire Protection Agency (NFPA) 1670, Standard for Operations and Training for Technical Rescue Incidents–1999.

This document is a noteworthy tool for being prepared to perform a safe and effective operation. Even if your department does not follow NFPA standards, at least read through this document to glean from it what you can to improve safety standards.1

NFPA 1670

Let us examine the document in greater detail to see what else must be done to be more fully compliant to help protect the department and its personnel from physical harm and legal liability.

Section 2-1.3 states that “… technical rescue operations are performed in a safe manner consistent with the identified level of operational capability … .” Section 2-1.4 says, “Operational procedures shall not exceed the identified level of capability established in 2-1.1.”

It is very important to identify and document what the team can and should not do. Consider two hypothetical teams.

Team A

This team documents that its surface ice capabilities are the following:

•Water moving less than one knot;

•Trauma-related incidents (e.g., snowmobile accidents);

•Subsurface searches performed on the surface with a reach pole, extending to a maximum depth of 15 feet;

•No unstable vehicle incidents;

•No contaminated water incidents as defined by A-7.2 (f) (b).

Team B

Team B`s ice capabilities are documented as

•Swift water-related incidents,

•Vehicle-related incidents,

•Long-distance operations extending one mile from shore,

•Limited-visibility operations, and

•Contaminated water operations as defined by A-7.2 (f) (b).

Team B must have documented Technician level training and equipment for ice operations involving swift water (7-3), vehicles (6-1), long distances, limited visibility (i.e., night, storms), and contaminated water [A-7.2.2(f)(b)]. Most likely, it is also a dive team with haz mat-tested dry suits and positive-pressure, full face masks.

Hypothetical Incident

Imagine the following incident in Team A`s jurisdiction. At 0200 hours during a snowstorm, a vehicle plummets off a bridge into a thin ice-covered river with 2.5 knots (250 feet/min.) of moving water. Should the ice rescue technicians (IRTs) of Team A go out to this vehicle 50 feet from shore in their neoprene ice rescue suits? Absolutely not!

We know this is a “no-go” operation because of the environment and the documented2 hazard analysis, resource assessment, and risk assessment: … “Potential hazards and their likelihood of causing an incident shall be identified.”

The first step in this approach assessment and risk/benefit analysis process is to compare the identified team capabilities with the hazards at hand:

•The team is not swift-water capable.

•The risks of rescuer fatality caused by immersion hypothermia and drowning are high.

•Neoprene ice rescue suits are not designed for moving water; they are likely to flood and do not afford the necessary swimming capabilities.

•Team A IRTs are trained to be tethered for surface ice operations, which may be more of a liability than a safety factor in this incident.

•Without being able to set up a moving-water static line system, the risk of rescuers` becoming entrapped in, against, or under the vehicle is too high. And what if the vehicle shifts or submerges?

Section 2-1.8 states: “The AHJ (authority having jurisdiction) shall ensure that there is a standard operating procedure to evacuate members from an area and account for their safety when an Imminent Hazard condition is discovered.” Team A cannot ensure this even if the vehicle remains stable. It may not even be able to fully assess and analyze all the risks and hazards, let alone mitigate them. With documented, identified capabilities and hazard analysis, the department and team members can clearly make the decision and show why this is a “no-go” situation.

Section 2-2.1 gives the first step of hazard analysis and risk assessment, stating: “The AHJ shall conduct hazard analysis and risk assessment of the response area … . Potential hazards and their likelihood of causing an incident shall be identified.” Further, “The AHJ shall conduct periodic surveys in the organization`s response area for the purpose of identifying the type of technical rescues that are most likely to occur.” (2-2.8) These procedures were described in greater detail in Part 1 last month. Refer also to A-7-3.5(b) and A-7.3.7a.

Part of this process involves identifying “the type and availability of internal resources … .” (2-2.3) Personnel are among the most important components of internal resources. The NFPA has three training categories for personnel: Awareness, Operations, and Technician (2-1.2).

Anyone who would respond to the scene of a possible ice rescue incident should be trained to the ice rescue Awareness level (2-1.6), which is usually a minimum of four hours of training. Awareness level personnel “shall meet the requirements of competent person” (7-2.1); see “NFPA 1670 Surface Ice Operations Definitions” above. The Awareness level is the lowest level of training, yet it has an important function: to prevent further injuries and problems on the scene.

The first person on the scene with Awareness level training who first assumes the incident commander (IC) position will have to accomplish many tasks within a short time. Delegation of officer positions and duties becomes critical.

The Awareness level involves the ability to perform and delegate the following duties (not necessarily in this order):

•Know where to go to assess the scene and stage the operation, based on predetermined, documented staging areas and the location of the incident.

•Identify and utilize PPE [e.g., personal flotation devices (PFDs), gloves, boots, hat, coat, antislip soles].

•Implement the assessment phase (7-2.2a) and resource assessment of existing and potential conditions and resources (7-2.2b), (A-8-2.3a).3

•identify hazards to life and health (7-2.2f).

•assess the number of victims and, if possible, the victims` conditions–ASAPS (Aggressive, Self-Rescue Capable, Alert but unable to help, Passive, Submerging).

•determine rescue mode vs. body recovery mode incident status (7-2.2g).

•Identify and document the resources necessary to conduct safe and effective water operations (7-2.2c). Determine who needs to be dispatched to the scene and what kind of response is necessary.

•Call for the appropriate personnel and response, including an ice diving rescue certified dive team. If a vehicle is immersed, a haz-mat team should be dispatched.

•Implement the incident management system (2-5.3). Establish a command post, staging areas for incoming agencies, safety officer (2-5.2), rescue team leader, and any other officers necessary to maintain a manageable span of control and a safe operation.

Mark a spot onshore in front of each victim.

Secure and manage the scene to maintain scene safety and site control. (7-2.2e)

–determine and mark hot (ice/water), warm (operational shore area), and cold zones.

–Keep bystanders, media, and the victims` families in the cold zone.

–Secure and check the condition of witnesses and family.

–Determine and direct the location and positioning of incoming vehicles to form windblocks and to prevent blocking of ambulance exit routes.

•Reassess the victim(s), if possible. If submergence has occurred, determine if the situation is a rescue or recovery based on time of submergence and the department`s standard operating guidelines (SOGs).

•Commence communication with the victim if operational or technician rescuers have not yet arrived (megaphone or other voice aid).

•Interview witnesses, and document the information on a profile map if operational or technician rescuers have not yet arrived (slate or pad, writing instrument, watch). (A-8-2.3h)

•Implement the emergency response system for water incidents. (7-2.2d)

Since ice rescues are probably not a regular occurrence, it is recommended that Awareness level certified ice rescue members keep an incident checklist in their vehicle, PFD, or wallet during the ice season. Such a checklist can be put on laminated ID-size cards.

Note: If Awareness or Operations level is the entirety of your training, do NOT go out on the ice! If the victim fell through, so very likely will you, and you may have less chance of survival than the victim. Two victims are never better than one.

OPERATIONS LEVEL–SHORE-BASED RESCUE

This level involves all awareness level skills (7-3.1) plus additional knowledge and skills specific to ice rescue, as well as the ability to perform shore-based rescue procedures (7-3.5f) without entering the hazardous atmosphere of water/ice. Operational certification usually requires two days of training followed by several annual practice sessions.

•Don appropriate PPE (PFD, thermal protection, gloves, boots, hat, cutting tool, whistle, contamination protection if needed). (7-3.4)

•Ensure that all of the duties listed under the Awareness level are being properly completed. And, “… evaluate the progress of the planned response to ensure the objectives are being met safely, effectively and efficiently.” (7-3.5e)

•”Ensure personal safety.” (7-3.5a)

•”Assess water conditions in terms of hazards to the victim and rescuer.” (7-3.5b)

•Assess ASAPS. (A-7.3.7e)

•”… Separate, isolate, secure, and interview witnesses.” (7-3.5c) Check witnesses` health status.

•”… determine the method of victim entrapment.” (7-3.5d) Is the victim in an ice hole, lying on the ice, caught by fishing line, or trapped in an ice shack?

•Document and implement the shore-based incident response plan and incident command system (7-3.5f):

— Help the victim perform self-rescue procedures.

— Reach.

— Throw (e.g., throw bags (7-3.5g).

–“Rapid extrication of accessible victim” (7-3.5p).

— Communicate with the victim(s).

— Assist Technician level rescuers with shore operations and tending.

–“Supply assistance with rigging and mechanical advantage systems to technician-level personnel.” (7-3.5h)

•”Procedures to deploy, operate, and recover any watercraft used by the organization” (7-3.5l). This does not refer to ice rescue transport devices, such as sleds and boards, that involve rescuer contact with the ice and immersion. Ice rescue transport devices require Technician level training.

•Surface water-based search operations (7-3.5q). This does not mean going on the ice. It may mean walking along the shore or working off a boat in areas of open water.

•”… Survival swimming and self-rescue” (7-3.5j) and appropriate watermanship skills.

•Identify and manage rescuer heat and cold stress. (7-3.5k)

•Safe and effective use of victim packaging devices employed by the organization. (7-3.5l)

•”Transfer victim information including location, surroundings, condition when found, present condition and other information pertinent to emergency medical services.” (7.3.5m)

•Further assess victim ASAPS status.

TECHNICIAN LEVEL–DIRECT EXPOSURE TO THE WATER HAZARD ZONE: ICE AND WATER: “GO”

The moment it becomes necessary to set foot on the ice, the operation requires Technician level rescue. The moment a rescuer steps on the ice, the entire operation changes because the rescuer is now directly exposed to the hazardous atmosphere–water. Ice rescue thermal protective suits, lines, harnesses, trained tenders, backup personnel, and more, are now all required. The operation is at an entirely different level. Technicians must meet all Awareness and Operations standards (7-4.1) and have more extensive knowledge; watermanship skills; and rescue skills, training, and equipment.

The duties of IRTs include the following:

•Perform risk-benefit analysis–“Go” or “No Go.”

•Plan “a response within the capabilities of available resources” (7-4.6a) and implement “a planned response consistent with the organization`s capabilities.” (7-4.6b)

•Perform self-rescue procedures. The technician must be able to swim and handle the exertion and should have an annual physical examination to check for hypertension, asthma, and other contraindications to performing Technician level ice rescue. Technicians must possess a level of watermanship skill and comfort appropriate to the required task (7-4.5). The level of water skills should be determined by the potential types of incidents documented during preplanning procedures. If incidents could occur two miles from shore, then rescuers need not only water skills but also very strong physical fitness skills.

•Implement the planned response. The most important aspect of Technician level ice rescue is to immediately and safely establish victim-positive buoyancy on contact (see photo above). The same remains true for Operations level efforts, but it may not always be possible if the victim is far from shore. The victim may first need to be reached and be brought closer to shore for rescuers to establish that critical positive buoyancy. And, therefore, technicians must be capable of conducting “go” rescues [(7-4.6d), (A-7-4.6d)] if reach and throw methods are not sufficient or possible.

Technicians must be able to use the ice rescue transport device and other ice equipment available (7-4.8); coordinate with and advise incident command, the responding dive team, and other responding external resources; and perform the termination phase of the operation.

NFPA 1670–1999 edition offers useful information for any department that would respond to a surface ice or other water-related incident. If you have not already started preplanning procedures, the time to start is now. And never forget the most important rule of every mission: There is only one job you have to do every time–go home.

2. Section 2-2.6: “The hazard analysis and risk assessment shall be documented.”

3. ASAPS is a tool developed by Lifeguard Systems for determining how to best communicate with the victim, the level of urgency, the number of ice rescue technicians to deploy, which rescue tools are most appropriate, which victim to approach first in a multiple-victim incident, and the equipment EMS personnel should have immediately ready.

4. A-7-3.7b states that rescuers should be able to recognize five types of ice. We find this information irrelevant for many reasons–for example, ice can change from minute to minute and foot to foot. Use procedures that work for all ice conditions, and be prepared to fall through. For additional reasons, see “Fall Preplanning for Safe Ice Rescue Operations, Part 1” (Fire Engineering, September 1999).


(1) Operations and Technician level personnel must be able to demonstrate appropriate self-rescue skills.


(2) Operations personnel must be trained to work with technicians so they can communicate with hand/whistle signals, know the maximum rate and safe techniques for pulling in lines, recognize rescuer hypothermia, and perform other assistance skills.


(3) Technicians need fitness and watermanship skills appropriate for the potential ice rescue operations in their jurisdiction. Just reaching the victim can require a tremendous physical effort.


(4) Medical care shall be provided for victims of rescue operations and shall be as a minimum at the basic life support (BLS) level (NFPA 1670–2-1.5). (Photos by Andrea Zaferes.)
