PLANNING FRAMEWORK
The Australian Adventure Activity Standard and associated Good Practice Guides cover weather. In the Australian Adventure Activity Standard v1.0 weather is covered as part of the Environment (5.1, p.8)
• weather and emerging weather variations
• severe weather and fire weather warnings
• bushfire and fire danger rating

Providers should identify and monitor weather and environmental conditions that might trigger modification,
evacuation or other relevant response.

The Core GPG Version 1.0 lists the documentation that must be available to activity leaders including;
• the risk management plan (completed for each activity)
• the emergency management plan
both of these documents should address Extreme Weather.

The Core GPG v.1.0 in section 5. Environment (p.19) has further details for our planning;

5.1 Environment related planning
A risk management plan must address all relevant environmental conditions.
Environmental conditions that should be considered include but are not limited to:
• weather forecasts, warnings and associated conditions (e.g. dry, snowmelt, heat, wind, rain, lightning) at the location and for the duration of the activity
• climatic conditions (e.g. drought, rain saturation, humidity)
• knowledge of the landscape of the activity area and how it relates to environmental conditions (e.g. is it sheltered or exposed, lightly treed or heavily timbered)
• the prevailing conditions of the area and what implications this has for environmental conditions (e.g. a long period of drought could affect the bushfire potential or the stability of trees during a strong wind event, during a wet period this can affect the likelihood of rivers and streams rising quickly)
• the potential access and egress routes, including for evacuation if this is required (e.g. are there river crossings, potential road closures, alternative routes)

5.1.1 Trigger points
A trigger point is a particular circumstance or situation that causes an action to occur.
Trigger points and actions to be taken in response should be developed before the activity.
A trigger point may be based on but is not limited to:
• a quantifiable or forecasted measure of particular weather or environmental conditions occurring (e.g. wind speed, temperature, river level)
• a specific or forecasted event occurring (e.g. lightning, strong winds)
• an index or rating reaching or forecasted to reach a specified level (e.g. fire danger rating).

Weather-related trigger points can be based on forecast and/or actual conditions. Consideration should be given to the possibility that actual conditions can be better or worse than forecast.

Reaching a trigger point sets in motion a responsive action, which may include but is not limited to:
• monitoring the conditions more regularly
• modifying the activity
• ceasing the activity
• evacuating the area.

Section 5.1.2 of the Core GPG v.1.0 covers Climate and weather, and gets into a bit more detail about monitoring weather forecasts. The focus will differ between activities eg. high winds for sailing, lightning for high ropes, snow fall for hiking in alpine areas.

A system should be in place to inform leaders in a timely manner if a severe weather warning has been issued for the area in which the activity is taking place.
Weather forecasts and alerts must be reviewed as part of the risk assessment before commencing an activity.
Monitoring of weather conditions must be undertaken during the activity.
Updated weather forecasts and warnings should be accessed or monitored during the activity

Adverse climate and weather conditions may require action, including but not limited to:
• consideration of an alternative venue
• modification or cancellation of the activity.

Bushfires, prescribed fire and fire danger are covered in the Core CPG v1.0 in section 5.2 (p.21-22). The monitoring of bushfire conditions should be undertaken regularly and, where practical, updated bushfire condition forecasts, warnings and alerts accessed throughout the activity.

5.2.1 Bushfire trigger points
Trigger points must be based on the fire danger rating.
The risk management plan and emergency management plan should include guidance on trigger points and associated actions for forecasted bushfire danger ratings of very high, severe, extreme and catastrophic, and if a bushfire event occurs.

SCOUTS VICTORIA
Scouts Victoria has an Extreme Weather and Emergency Management guideline [PDF] Issued: January 20 2020 which has been updated with Interim Extreme Weather and Emergency Management Report (Jan 2023 – Due for update Spring 2024). (Some bad document management there as the older document is the one located via a search).

The purpose of this guideline is to define the processes that should be implemented to ensure the safety and well-being of all Scouts Victoria members, volunteers and employees during extreme weather events and emergencies.

This guideline need you to know if the area your activity is taking place in is a designated ‘Bushfire Prone Area’. To determine if your activity or campsite is in a bushfire prone area, go to https://mapshare.vic.gov.au/vicplan/ and enable Bushfire Prone Areas layer. (Note that areas with a Bushfire Management Overlay are still defined as Bushfire Prone Areas.)

From the Tool Bar > Map
Layers: Bushfire selecting BMO – Bushfire Management Overlay and BPA – Bushfire Prone Area


.
From the Interim Extreme Weather and Emergency Management guideline (Jan-2023);

Cancel, Reschedule or Relocate an Activity
The Leader in Charge of an activity must cancel, reschedule, or relocate a Scouting activity at the earliest opportunity if any of the following occur:
• A fire danger rating of “Catastrophic” is declared for the fire district in which an activity is planned, and the activity is in a designated “Bushfire Prone Area”
• A fire danger rating of “Extreme” is declared for the fire district in which the activity is planned, and the “Fire Danger Rating Trigger Actions” cannot be complied with.
• An “Emergency Warning”, “Watch and Act Warning”, or “Recommendation to Evacuate” is issued for the location of the activity
• A warning is issued against travel to the location of the activity

❝ I can minimise damage to the environment while bushwalking. ❞

— Scouts Australia, Outdoor Adventure Skills – Bushwalking – Stage 5

On top of our standard Leave No Trace principles we should be allowing for damage to the environment in our activity risk assessments. A big risk that you will come across when hiking in Victoria is Cinnamon Fungus (Phytophthora cinnamomi).

Cinnamon Fungus (Phytophthora cinnamomi) is a microscopic, soil-borne disease-causing organism that attacks and destroys plant root systems causing plants to die through lack of water and nutrients. Patches of dead or dying vegetation can indicate the presence of this silent killer and grass trees are particularly susceptible. It is spread through infected plants and the movement of contaminated soil and gravel, and there is no known cure.
Parks Victoria

From a camping and bushwalking perspective, how do we prevent Cinnamon Fungus spread?

  • Be clean on entry and exit – camping gear should be free of soil, gravel and mud prior to entering or leaving any park, reserve or campsite (particularly in high risk areas). Don’t bring soil or gravel in – and don’t take any home!
  • Use boot cleaning stations where available – they are there for a reason.

GOW - Phytophthora boot cleaning station
Be clean – Washdown Procedures
Hygiene protocols seek to limit the human assisted spread of P. cinnamomi. Washing your boots at boot cleaning stations along your hike, and cleaning camping gear is important. Cleaning your tent pegs, ground sheet / tent foot print, and even tent poles where they dig into the dirt.
Disinfect your gear with a disinfectant;

And a few more to think about …
The Invasive Species Council’s Keep your gear clean in the wild campaign lists a few other pests to have in your risk assessments.

  • Didymo ‘rock snot’
  • Weeds (how many seeds do you have on your socks?)

In March 2023, Scouts Victoria released a safety bulletin Bulletin Three: Improvised Liquid or Gas Fuel Stoves prohibiting the use of any improvised liquid or gas fuel stoves in Scouting.

❝ Unfortunately, the stoves produced were low quality and there were some leakages of fuel. Further, when one of the stoves was being refilled a flame flashed back to the fuel bottle which understandably startled a youth member.
The youth member accidentally kicked a stove with their foot which splashed ignited methylated spirit onto two other Scouts. One of our Scouts sustained serious burns that required specialist treatment including a skin graft.
Trangia stoves are already part of our program and provide the same output whilst being safer because of their inbuilt safety features including the extinguishing ring and windshield. ❞
— Scouts Victoria. Bulletin #3 Improvised Liquid or Gas Fuel Stoves

There are some problems occurring here.

Reading the text of this bulletin we see some troubling approaches to use of portable camp stoves,

  1. there was some (unmanaged) leakages of fuel
  2. a stove was being refilled a flame flashed back to the fuel bottle
  3. a youth member accidentally kicked a stove with their foot

Methylated Spirits (or denatured alcohol) stoves are the go to stove in the Led Outdoor Activity (LOA) sector, and as such there is a lot of documented information for their use, and their issues, available to the Outdoor Practitioner.

There are ‘known knowns’ in the Outdoor Education / Outdoor Risk communities with skill sets that are taught & implemented to manage the risks. Going back to the early Uploads Project reports it has been clear that campcraft (i.e. cooking, campfires; 5.7 incidents per 1000 participants in 2014-2015) has a series of risks that should be mitigated.

How is the risk mitigated? In an Outdoor Education context – via systems that are put in place to avoid issues.

In 2021, The Uploads Project created a PreventiMap for Incidents in the Outdoors: Campcraft Activities which gives a good view of the areas that need to be addressed for a successful risk management system.

February 10, 2021 – Campcraft Activities [1]
Since September 14, 2018, 473 injury or illness incidents relating to Campcraft Activities have been reported. Although, 89% of these incidents were minor in severity, 7% of the incidents were reported with a potential severity rating of serious, severe or critical. In addition to an overview of a subset of data we typically provide in our Infographics, such as, the types of incidents and frequently reported contributory factors, this infographic presents a PreventiMap for Campcraft related incidents. The PreventiMap shows a network of interventions that could be explored to prevent and management campcraft related incidents.

Incidents in the Outdoors - Campcraft Activities

Further information is provided via Outdoor Education training in the methods for managing these cooking systems. (In the Scouts Victoria context, this skill set should be being provided to Leaders via the ‘Scouting Adventure’ training. (Scouts Victoria (2023-Feb) What Can I do? A guide to running Adventures Activities in Victoria))

Group management and cooking stoves
Lightweight cooking stoves have a good safety record, but the combination of people, fire, fuel and lack of knowledge can give rise to a serious accident. If cooking in groups, then it is important to ensure:

  • there is a safety brief to the whole group
  • that users have been trained in the proper use of the stove
  • that systems have been set up to minimise the possibility of burns
  • that first aid is on hand should a burn occur
  • that there is equipment to put out a fire

— Group Management and cooking stoves
p.46-47 in Christine Froude, & Scott Polley (2011) Outdoor education : foundations for tertiary and senior secondary education. 2nd Edn.

In A practitioner’s first-hand perspective on ways to address issues raised around campcraft incidents (PDF) Dr. Clare Dallat gives case studies, and goes into some of the emerging themes surrounding cooking safety. This is a must read document if you are using hike stoves in your program. She also hits the nail on the head with how accidents occur;

❝ As we know, accidents and incidents in complex systems are caused by multiple factors and there is no such thing as a root cause. ❞
— Dr. Clare Dallat [3]

Trangia Stove

Knowing this, lets look at those issues again:

As with any of our skill sets in the Outdoor Adventure Skills there are safe approaches if we know how to use and check the equipment we are using correctly. If we do not have this knowledge we increase our risk.

1. “there was some (unmanaged) leakage of fuel”
Commercial Trangias, or similar commercial stoves, get damaged, and leak, and can cause similar impacts in an uncontrolled environment.
Using a fuel bottle with a safety valve for safe, controlled fuel outflow also reduces this risk.
Check all equipment before it gets used, and have procedures for the use of stoves or fire so that any spilled fuel during refueling cannot be accidentally ignited.

2. “a stove was being refilled a flame flashed back to the fuel bottle”
The solution to this is good refilling practices using a Fuel Dump system where the ‘the car goes to the fuel station’.

Policy of risk minimization in the use of fuel stoves [4]

  1. Encourage users to test whether the burner is still alight by holding the back of the it hand over it first
  2. Always instruct users to pick up the burner, and remove it from the stove before refilling. It is a much better scenario to treat a minor bum to the fingers if indeed this is the outcome!
  3. Instruct your groups to establish a “fuel dump” where all fuel is stored in a central area, which is easily observed and all users to bring the burner to the fuel to refill rather than the reverse.

Importantly, the Fuel Dump is in a central area of the camp, away from the Cooking circle (covered in item 3) so that it is about 10m away from stoves [5].
An important safety consideration, especially if you have novice stove users in your group, is not to use mixed fuel types in your fuel dump.

Policy of risk minimization in the use of fuel stoves [4]

  • Never allow a group to have fuel of differing types, i.e. trangia with a few MSR shellite burning stoves…. a sure recipe for disaster, and it is a more regular occurrence than one would think.

3. “a youth member accidentally kicked a stove with their foot”
If a youth member is kicking a stove, you have a poorly implemented cooking circle procedure.

Why have a cooking circle?
The cooking circle imposes a process onto the cooking, with clearly defined spaces and roles this minimises human traffic and congestion in the kitchen. This adds a risk management mitigation to both the food cooking (burns) and preparation (cuts) activities.
There are variants on the cooking circle, here’s the one that I favour;

The Cooking Circle

  • Cooking and food preparation are supervised activities
  • Always use stove on a flat spot with ideally no grass/ undergrowth so that stove is stable
  • Stoves are placed on the ground (see [3] for a discussion on this).
  • Center Circle: The center circle is a safe space – nobody walks into it – this reduces the risk of a Trangia being kicked over as there is no traffic passing the Trangia
  • The Trangias are setup around the Center Circle. Only the “Cook” should access this area, one cook per Trangia (use the Trangia strap as a head band to identify the Cooks).
  • Cooks should be squatting – this reduces the burn risk as the cook is able to move away quickly in the event of splashes and spills.
  • The Centre Circle should be at least 10m away from the fuel dump and at least 5m away from tents.
  • Outer Circle: The next circle out is the preparation space. Food preparation, chopping, peeling, etc. occurs here.
  • The Cook can collect from the preparation area, the preparers cannot go to the Cook.
  • No one else should enter either of these areas until the Cooking Circle is packed away.
  • Cleanup uses the Cooking Circle (for hot water for washing) and the Cooking Circle can be decommissioned once all Trangias are packed down for transport.

Where are we now?

Looking at what happened in the scenario quoted from the Safety Bulletin, and ignoring the ‘Penny stoves’ issue, there were problems with stove management. The scenario described had both poor “cooking circle” and fuel management “fuel dump” protocols. There is a large disconnect from the skill levels that are required for Guides & Instructors via the National Adventurous Activities Framework (NAAF) and what was occuring.

The Australian Adventure Activity Standard and related Good Practice Guides cover cooking in the Camping Good Practice Guide Version 1.0;

6.2 Use of cooking equipment or fire
Incident data suggests that there is an elevated likelihood of incidents when cooking or using stoves.
There must be appropriate training in the use of stoves.
There must be appropriate supervision when participants use stoves or fire

Procedures for the use of stoves or fire must include:
• establishing a cooking location and arrangement that minimises human traffic and congestion and avoids movement were users step over stoves
• having stoves located on a stable, flat and level base
• refuelling gas or liquid fuel stoves does not occur while it is still alight
• any spilt fuel during refuelling cannot be accidently ignited
• extinguishing the stove occurs before moving its location
• fuel containers being locating away from possible ignition sources
• use of suitable equipment to hold and manipulate hot cooking equipment
• passing hot equipment, water or food over any part of another person is avoided
• stove or fire users being situated to quickly avoid or move away from hazards that might burn them
• stoves or fire only being used in well ventilated spaces to prevent a build-up of toxic gas fumes
— Australian Adventure Activity Standard, Camping Good Practice Guide Version 1.0

These elements of Good Practice are addressed through using the procedures that we have seen above; Fuel dumps with refilling procedures, and Cooking Circles, combined with suitable supervision.

❝ Whenever I look at something going bad, I ask;
Were there systems in place? Were they up to date, were they being implemented.
Systems. Systems. ❞
Gordon Graham

From the Uploads report we can see that it is critical to both “Develop policy/guidelines around campcraft equipment” [1] and have training in good practice for the use of hike stoves (such as cooking circles, fuel dump, and refilling practices).
Once you have your management systems in place, it should not matter which liquid fuel stove you are using – your system will allow you to cook safely. As you progress through your Outdoor Adventure journey you will meet many more stoves than the standard Trangia – your systems should allow for their safe use.

This is a good question – and one that should be being answered in your risk assessments. The best ‘go to’ reference for first aid requirements in our risk assessment documentation for Adventurous Activities is the Australian Adventure Activity Standard (AAAS).
We need our descriptions and reasoning to be current Good Practices.

❝ 7.6.3 First aid competencies
Due to the nature of activities, there is the potential for injury or illness. Preparation to deal with any foreseeable injuries or illnesses, such as providing suitable equipment and undergoing appropriate training, will help with the response to any such occurrences. […]
The minimum requirement for first aid training must be as listed in Appendix M – Leader competencies. A higher level of first aid qualification should be used for activities and programs that are in remote areas, as listed in Appendix M – Leader competencies. ❞

( p.29, Core Good practice Guide v1.0 )

Our first take away is that there is a minimum requirement for first aid training.

❝ M2 First aid competencies
The minimum requirement for first aid training must be the unit Provide First Aid unit code HLTAID003, or its equivalent.
A higher level of first aid qualification should be used for activities and programs that are in remote areas, with the minimum requirement being the unit Provide First Aid in a Remote Location Unit code SISOOPS305A, or its equivalent. ❞

( p.63, Core Good practice Guide v1.0 )

The next takeaway is that a higher level of first aid qualification should be used for activities and programs that are in remote areas. We still haven’t had remote defined, so we need to look up the definitions.

Note: HLTAID003 is superseded by HLTAID011, and SISOOPS305A is superseded by SISOFLD004

❝ Glossary
[…]
Non-remote: generally a location that is 30 minutes or less from reliable telephone access, 20 minutes or less from vehicle access, and one hour or less from access to professional medical assistance (also see remote).
[…]
Remote: a location that is more than 30 minutes from access to reliable telephone access or more than 20 minutes from vehicle access or greater than one hour from access to professional medical assistance in all foreseeable weather (also see non-remote). Note: access to professional medical assistance needs to account for the foreseeable possibility that professional medical assistance via helicopter may not be possible due to terrain and/or weather when determining access times ❞

( p.39-40, Core Good practice Guide v1.0 )

This definition of ‘remote’ suggests that remote first aid should be the requirement in many risk assessments that are still ticking the box with a provide first aid level.

A paramount principle for all activities is Challenge by Choice. It means that we as facilitators OFFER both physical and psychological challenges to individual participants but THEY CHOOSE their level of engagement in the particular challenge. Our challenge courses and activities are designed to offer differing levels of challenge to participants. We operate inclusive programs meaning anyone of any ability is able to join. Challenge by choice is a belief in which we, the facilitator(s), respect the right of the individual participating to choose the degree in which they participate during an activity, always encouraging participants to step out of their comfort zones but never forcing them to. Individuals should feel comfortable and safe at all times. Keep in mind that all participants come with different levels of fears. It is important to celebrate the tiniest steps that they might take out of their comfort zone.

Based on: Girl Scouts of Eastern Iowa and Western Illinois – Challenge course Guidelines.

Stage 3// Alpine
Do > I have built an emergency shelter in snow, with a small group.

Emergency Shelters

If you become lost or injured, the first and most important order of business is to arrange for protection from the wind, as this will increase the odds of survival. This may be a temporary shelter, or may need to be more substantial. A simple wind break can be created with snow blocks, or you can shelter in the cleared area under a tree. The quickest emergency shelter to construct in snow is a trench. Other emergency snow shelters are snow mounds (Qunizhee huts), snow caves, and igloos.
