Winter Nighttime Rope Rescue Training in New Vineyard

FSAR held an evening rope rescue training February 17th.  The team practiced the skills necessary to safely extricate a patient from a low angle slope. Several anchors and rigging systems were built to safely protect a litter attendant and raise the patient. The next quarterly training training will be held in April or May.

Winter SAR Training at Acadia National Park

On February 6th and 7th ,  Pat, John, and Mathias attended the Maine statewide winter training on Mount Desert Island.  The two day program was hosted by Chris Wiebusch from Acadia National Park Service (NPS) and held at the winter headquarters.   Besides Franklin SAR, other teams attending included, Wilderness SAR, Mount Desert Island (MDI) SAR, Mahoosic Mountain rescue team, Pine Tree SAR , NPS and Baxter State Park rangers.




 There were two different afternoon field scenarios. Both encompassed notification, organization, navigation to the victim, patient assessment, treatment and transportation. One of the scenarios involved a high angle pick off of the victim on an ice route.  The second involved a haul system where the victim and litter were in a difficult terrain.
Sunday we visited Beaver Bog pond to practice ice rescue techniques. At times we had 4 people in the water and it proved to be quite interesting!
After Fridays snowstorm where Acadia picked up a foot of snow, the scenery was spectacular.  Working together with other agencies and sharing ideas and techniques is always dynamic and this training was no exception. 
Many thanks to Chris and his staff of fellow rangers for organizing the event, as well as for their hospitality and accommodations.





Some of the topics and techniques we covered included:
·         Cold weather/winter emergencies and treatment. 
·         Crampon and ice axe use.
·         Avalanche and beacon use.
·         Surface ice rescue.

Conducting a Sound Sweep for Search & Rescue By: Martin Colwell

Conducting a Sound Sweep

Instructions to Search Teams  


(posted on FSAR blog with permission from M. Colwell)


Introduction:

The Sound Sweep is an efficient form of grid-searching that utilizes sound to help find a missing person. Recent Sound Sweep field experiments (ref 1,2,3) have shown that there is a high probability of searchers finding a missing persons at three to four times the searcher spacing required for a normal, summer visual grid search. This means that search teams may cover a three to four times larger search area if they employ sound while conducting their grid search.

Compared to earlier historical data (ref 4) the Sound Sweep area coverage is up to 6 times greater in dense coniferous forest in summer, 9 times greater (at a low voice-response volume) in winter and 23 times greater in sub-alpine forest in winter. The Sound Sweep therefore is an important new tool for field teams to employ, both for area searching and as they conduct their initial hasty (trail) searches.

Limitations:

The Sound Sweep technique is based upon the presumption that a missing person will respond with sound, usually by shouting, if he/she hears a loud sound generated by the searchers. For the technique to work the Sound Sweep must be conducted while the missing person is responsive and still capable of an audible (typically, shouted) response. This means that Sound Sweeps should be conducted within the first few days, and preferably within the first 24-48 hours, of search notification.

Procedure:

Base Radio Operation

A base radio is set up in a location that will have good coverage of the search area or route. A radio operator will repeatedly broadcast the following radio prompt to all the searchers: "Four, Three, Two, One, Blast ...". This prompt will be re- broadcast typically every one or two minutes - for the entire duration of the Sound Sweep.

(An assistant radio operator is usually required to relieve with the radio-prompt duties).

See the attached table for the required prompt intervals.

Alternatively electronic ‘beeper’ devices have been built that automatically insert four short warning tones then one long (‘blast’) tone into the base radio transmissions, to automatically prompt the searchers to perform their whistle-blasts at the required prompt intervals.


Note: These radio-prompt broadcast intervals, for both area and trail searching, have been chosen from the POD search data to ensure there is a 100% probability that searchers will hear an audible voice-response from a missing person. These radio-prompt intervals correspond to a distance travelled betweens whistle blasts of not more than:

18m (59ft) in Dense Coniferous Forest - in summer or winter 60m (197ft) in Open Sub-Alpine Forest - in winter.

Sound Sweep Field Operation

Sound Sweep Area Searching:

Every searcher in the team is equipped with a VHF radio, a map, compass and a loud whistle. (The Fortron Fox40 whistle is recommended).

The search team members are spaced out at very wide spacings, as specified in the accompanying Sound Sweep Probability of Detection (POD) tables, along the search area baseline. At these spacings the searchers will often not be able to see each other and so radio communication will have to be used to maintain contact between the team members.

Each searcher, upon reaching his/her starting location along the search area baseline, should identify and flag this location and then radio to base that he/she is commencing the Sound Sweep.

There is no need to the searchers to start their sweeps simultaneously.

The searcher shall follow the compass bearing assigned by the search manager. Occasional brief radio communications with other team members, and the team leader, should be maintained, to ensure team safety.

Every time the searcher hears the Base radio warning prompts commencing he/she shall stop, place the whistle in the mouth and perform a simultaneous loud whistle blast on hearing the radio "Blast " prompt. (To preserve hearing it helps to plug the ears during the whistle-blast).

Following the whistle-blast maintain five seconds of radio silence. During this period the searchers stop and carefully listen for an audible voice-response from the missing person. If no audible or visual response is received then the searchers continue travelling until they receive the next radio prompt. The searchers repeat this base-prompted whistle-blast procedure, and listening for an audible response, while they travel the entire search area.


The search manager may request that additional Sound Sweeps be performed, preferably at right-angles to the previous sweep.


These additional sweeps are necessary if the missing persons probability of detection has to be increased.

Sound Sweep Trail Searching:

A Sound Sweep trail search, for a normal voice-response person, approximately doubles to triples the width of the trail-searched ‘corridor’ compared to standard visual searching. This Sound Sweep corridor has a bell-shaped POD profile which starts at 100%POD on the trail, and tapers down to 20%POD at the far edges of the corridor. This sound-swept corridor is approximately 270m(886ft) wide in dense coniferous forest under summer conditions, and 560m(1837ft) wide in dense coniferous forest, or open sub-alpine forest, under winter conditions.

Sound Sweep trail searching uses exactly the same Sound Sweep procedure of regular base-radio prompts, searcher whistle-blasts and listening for an audible voice-response from the missing person, as the team follows its trail or route. Because the team is moving together on the trail only one radio per team is usually required. (Of course the previous area searching instructions of searcher-spacing and following compass bearings do not apply for Sound Sweep trail searching).

The Sound Sweep radio-prompt interval is usually more frequent for trail searching than area searching due to the normally faster travel speeds of searchers on the trails. While the trail search teams may find the frequency of these whistle-blast prompts somewhat inconvenient it is not advisable to extend the period between whistle-blasts much longer than specified in the Sound Sweep Radio-Prompt table, doubling these prompt intervals will drop the probability of hearing a normal voice-response from 100%POD down to approximately 85%POD.

One possible option is to have each member of the trail search team take turns in performing the whistle-blast, and perhaps not stopping while listening for the subject’s voice-response.

The default recommended Sound Sweep Trail Search radio prompt intervals are:

Every 20 seconds on trails through dense Coniferous Forest, (in summer or winter).

Every 1 Minute on trails through open Sub-Alpine Forest (in winter).


Note: Doubling these prompt intervals will reduce the POD of hearing a normal voice-response from 100% POD down to approx. 85% POD.

Sound Sweep Trailhead Searching

Searchers in vehicles and trailheads can also apply the Sound Sweep technique to their search efforts. A radio-equipped vehicle parked at a trailhead or boundary of a search area may perform horn-blasts on cue from the base-radio prompts, simultaneously with the searching field teams. The louder sound generated by the vehicle horn may awaken or alert the subject, who may not have otherwise heard the whistle blasts, particularly if they were asleep or close to noise sources, such wind or rushing streams.

Sound Sweep Road Searching

The Sound Sweep may be used by radio-equipped vehicles searching from a road within the search area. For example, using four radio-equipped vehicles:

The four vehicles are driven along the road until they are exactly 1km or 1 mile apart (depending on whether the odometer reads in kilometers or miles). On hearing the base-radio prompt each vehicle then simultaneously sounds its horn and the driver then listens for an audible response from the subject. If no response is heard the convoy then drive exactly 0.1km (or 0.1miles) along the road using the vehicle odometer to track their distance travelled. The vehicles then stop, wait for the base-radio prompt and then repeat their simultaneous horn-blast. Again the drivers listen for an audible response from the subject, if none is heard the vehicles are then driven another 0.1km (or 0.1 miles) and the simultaneous horn-blast and listening procedure is repeated.


This drive/blast/listen process is repeated until each vehicle has driven exactly 1.0km (or 1.0 miles) i.e. until they have reached the original starting location of the vehicle in front. At this time the 4-vehicle convoy then travels 4km (or 4 miles) further up the road, i.e. until the last vehicle reaches the final finishing position of the first vehicle. At this time all the vehicle drive forward another 0.1 km (or 0.1 miles) and the whole procedure is repeated for another 1km (or 1 mile) and the convoy then moves forward again. Using this procedure a fairly large area adjacent to a road can be searched quickly with minimum manpower.

The POD at 0.1km (100m, 328ft) driving intervals i.e. up to 0.1km either side of the road for normal voice response, is 42% for dense coniferous forest in summer and 62% for sub-alpine forest in winter. For a quiet voice response in subalpine forest in winter the POD is 42%.

The POD at 0.1mile (528ft) driving intervals i.e. up to 0.1miles either side of the road for normal voice response, is less than 5% for dense coniferous forest in summer and 34% for sub-alpine forest in winter. For a quiet voice response in subalpine forest in winter the POD is also less than 5% Clearly a shorter driving interval, such as the 100m, 328ft interval above is preferable to avoid the subject's voice response from becoming inaudible.

Sound Sweep comments:

As the Sound Sweep relies heavily on radio communications uneccessary radio-chatter should be kept to a minimum.
Having large numbers of searchers, all operating radios, raises the possibility that the radio prompt, and particularly the important following five seconds of radio silence, will be masked by radio communications.

Radio communications between the radio-prompts is acceptable but no transmissions should be permitted during the radio-prompt and the following five seconds of radio silence.

The searchers should occasionally perform a radio check with base, especially if they have difficulty hearing the repeated radio-prompts. The searchers may have moved out of good radio contact with base as they travel through the search area or route.

If radio communication becomes poor then the base radio will have to be relocated. This may happen when searchers start, with good communication, on top of a ridge, but lose communication as they move down to the valley bottom. If necessary, plan to have an alternate base radio location in place, ready to restore communication as the searchers move through the search area.



RECOMMENDED SWEEP SEARCH CONDITIONS

--- For SOUND SWEEPS ---

Area Sound Sweep Search Conditions:


Typical Summer Area-Search Speeds in Dense Coniferous forest:

0.4Km/hr ((0.25 miles/hr) in rough mountain forest with moderate to heavy bush, Sound Sweep whistle-blast every 2 minutes.

1.0Km/hr ((0.62 miles/hr) in fairly level forest with light to moderate to bush, Sound Sweep whistle-blast every 1 minute.
Typical Winter Area-Search Speeds on firm snow with most of the bush buried. Dense Conifereous forest: 0.62Km/hr (0.39 miles/hr)
Open Sub-Alpine forest: 0.86Km/hr (0.53 miles/hr) *Sound Sweep whistle-blast every 1 minutes. **Sound Sweep whistle-blast every 2 minute.

4-Day Rigging for Rescue Rope Rescue Workshop on MDI

Photos and story by FSAR Pat


On October 19th through the 22nd Pat, John, Shannon, and Paul attended Rigging for Rescue (RFR) training on Mt. Desert Island.

The 22 students that participated in the training included members of various MASAR teams throughout the state as well as Acadia National Park rangers. 

Rigging for Rescue is a company out of Ouray Colorado which offers technical ropework seminars that focus on applying critical thinking and systems analysis skill required to competently incorporate ropework and rigging into effective rescue systems.  The 4 day course was conducted by Mike Gibbs, RFR founder, and Leo Lloyd, instructor. 

Each day began with classroom training held at the Seal Harbor Fire Department.  Practical training was held at various amazing sites overlooking the Atlantic Ocean!  

Some of the topics and techniques we covered included:
  • Safety factors and rescue safety systems
  • Anchor points and systems
  • Command and Communication
  • Systems analysis and scene size up
  • Simple, compound, and complex pulley systems
  • Parallel plaquettes
  • Radium release hitches
  • Rescue belays and hauls
  • Pick off’s lowering with a self-belay
  • Horizontal and vertical Stretcher techniques on raises and lowers

Many thanks to Steve Hudson of Mount Desert Island SAR for organizing the event, along with Davin and the fellow MDISAR team members for their help with equipment, home baked goodies, and driving directions around the Island!

We also wish to thank the 'Friends of Baxter' organization, the Savoy Foundation and FSAR, for their generous support which helped offset much of the cost of this very productive and informative workshop.
