A: Wolverines are 9-25 kg, max 32.

They have been known to prey on animals as large as moose,

but more often are carrion eaters. Don't disturb its kill. Give it

a wide berth. If it's attacking you, presume it's prey behaviour and

Subject

What is this lesson plan about?

This section is about knowing when to bring in specialized skills.

It builds on the understanding of hazards that the students have previously developed.

This section could potential by renamed "specialized skills".

Authors

List who wrote this lesson plan.

Scope

What is included in this lesson, what's not and why.

SAR Fundamentals Manual: Ch.8 "Problems Associated with Specific SAR Environments"
Basic SAR Skills Manual:
  • Ch.9 "Environmental Hazards in SAR"
  • Ch.10 "Animal, Insect, Snake Hazards"

The above material is assigned readings. This lesson plan builds on it.


Prerequisites

What should students already know/have accomplished before the lesson is presented.


The students should already have completed the assigned reading.

Objectives

At the conclusion of this lesson the participants:

  1. will be able to ...

Local Hazards

Lead a discussion of the hazards SAR workers might encounter in our area. Write on flip chart.'

Some examples:

  • cliffs
  • swift water
  • avalanche
  • ice
  • extreme cold
  • bears
  • becoming isolated



Recognition

Which are hazards you'd have known about before leaving the CP?

Which are hazards you might only discover in the field?

Circle examples



Risk

For one or more of the examples, discuss what the risk could be with the hazard. Might have to make the example more concrete with specific details.

What are the worst case scenarios associated with the risk?

  • Discomfort?
  • Damage to equipment?
  • Injury?
  • Death?

What is the likelihood of these consequences?

Risk = Impact x Probability



Benefit

What are the consequences of not facing the hazard?

Not your emergency.

A dead subject is no longer an emergency.

Risk vs. Benefit



Deciding

We need you to do the opposite of what your body is telling you to do.

Adrenaline poisoning

  • fight or flight

We need your brain to be working

  • S - Stop
  • T - Think
  • O - Observe
  • P - Plan


Who decides?

Both you and your supervisor can decide the risk is too high for the benefit.

Team in the field has the most detailed information about the hazard.

Overhead team has big picture.

Talk to your Team Leader. Talk to the Command Post.



Strategies

List the 4 categories

  • Avoidance
    • withdraw from the situation
      • Don't send our team into an avalanche environment
    • remove the risk
      • Have the rancher move his buffalo to another field
  • Reduction
    • mitigate the risk
      • carry avalanche equipment
      • have avalanche tech assess and plan route
      • train in avalanche techniques
  • Sharing
    • ask someone else to do for us
      • bring in a speciality team, technician
      • Technical personnel should be used for technical rescue [Search and Rescue Fundamentals manual Page 99]
    • insurance
      • WCB
  • Retention - accept
    • cross the river

Have students give examples of each categories that bring out the sub strategies



Risks to the Subject

  • unsafe rescue techniques
  • untrained medical interventions
    • medications



Risks to others

Most technical rescues transform but do not eliminate the risk. Move it to an area where there shouldn't be exposure.

But having untrained people or bystanders around, they may be exposed to risk.

Example: Rope rescue uses the ropes to reduce risk of falling, but if there's an equipment failure people standing in an otherwise safe area may get swept over the cliff.

Stay away unless specifically directed to help.



Risk of making the Search Harder

  • scent contamination
  • untrained tracking



Legal Risks

  • exceeding authority
  • exceeding scope of practice



Speciality Teams

What are some of the specialty teams that could be brought in?

Use list of hazards from before

  • higher medical training
  • transportion
    • helicopter
    • snowmobile
  • rope rescue
  • swift water rescue
  • ice rescue
  • fish & wildlife
  • police
  • animal control

Which teams could be part of a SAR group? Which are outside the mandate of a SAR group?



Doing it yourself

Accepting the risk.

Some SAR workers have unrecognized skills. We ask SAR workers to know how to improvise.

"A little knowledge is a dangerous thing."

"What you don't know, will kill you."

The single greatest problem is that responders underestimate the hazard. [Search and Rescue Fundamentals manual, Page 102]

Discuss with Team Leader and Command Post. Err on the side of caution.



Common triggers

At what point should you stop and evaluate the risk?

Request speciality team. Ask for overhead decision.

general guidelines:

  • cliffs
    • no closer than 2 meters of 2 meter fall
  • other hazards with defined, unmoving boundary
    • no closer than 2 meters
    • swift water
  • moving subject on slope
    • 20 degrees
    • hand on hip, elbow angle technique
    • other situations where consequences of slip are severe
  • avalanche
    • don't enter area without equipment and risk assessment
  • ice
    • avoid if possible
    • cross only good, clear, solid ice: 5 cm walking, 13 cm snowmobile
  • extreme cold, wind chill
    • individual assessment of adequacy of clothing, starts at +10C
  • bears
    • recent sign
  • isolation
    • individual assessment of skills
    • train to 24 hr

Frequently Asked Questions

A: Wolverines are 9-25 kg, max 32. They have been known to prey on animals as large as moose, but more often are carrion eaters. Don't disturb its kill. Give it a wide berth. If it's attacking you, presume it's prey behaviour and fight back.
