Study Notes
Mine Rescue Team Structure and Operations
- A mine rescue team consists of an active team, a back-up team, and a team at rest, with each team having a specific role and duration of operation
- The active team is responsible for the initial response and rescue efforts, while the back-up team provides support and relief, and the team at rest recovers and prepares for the next rotation
Mine Rescue Team Members' Roles and Responsibilities
- Team members are responsible for communications, decision-making, and personal protective equipment requirements
- They must also ensure team response readiness, breathing apparatus and auxiliary equipment response readiness, and safe operation of all rescue equipment
- Team members are responsible for directing and assisting each other at the scene, determining and inspecting all aspects of a rescue operation, and establishing and maintaining incident scene security and control
- They must also explore the affected area of the mine, perform rope work and rigging, firefighting, and first aid and extrication
Information Gathering During Emergency Response
- Information gathered during emergency response includes nature and location of emergency, number of people/injuries involved, weather conditions, and equipment involved and access to the scene
- Details observed en route and at the scene, including signs of hazardous conditions, are also important
- Information gathered during size-up is categorized as factual (known or confirmed) or probable (assumptions made based on situation)
Personal Protective Equipment and Safety
- Personal protective equipment includes head protection, eye and face protection, hearing protection, respiratory protection, hand protection, foot protection, and protective clothing
- A clean area with good lighting, a safe location, and necessary tools and supplies are essential for rescue operations
- The travel way from the base to the surface must always be assured of good air, and underground-to-surface communication must be uninterrupted
Avalanche Safety
- Avalanches rarely start on slopes steeper than 45° as snow sloughs off continuously rather than accumulating
- Snow conditions, environmental effects, and an external event that triggers the slide contribute to avalanche risk
- Trigger points, including snow layers, shallow areas/variable depth snow packs, and points of weakness, may contribute to avalanche development
- Start from a point, and set in motion progressively; require snow with poor cohesion, similar to dry sand; and are usually confined to surface layers and relatively small
Avalanche Prevention and Response
- Wear mitts and hats, tighten clothing, and loosen larger packs in case they need to be quickly removed
- Assign a spotter at the top and bottom of the track and agree on a warning signal
- Cross quickly, and maintain space between rescuers to minimize the risk of exposure to an avalanche track
Ice Safety
- Type of ice includes river or lake ice, clear or natural ice, and slush ice
- Cracks in ice may affect its ability to support a load
- Loads should be reduced by at least 15% on river or lake ice
Heat-Related Illnesses
- Symptoms of heat-related illnesses include fluid loss, sudden fainting, cool, moist skin, weak pulse, and elevated body temperature
- Treatment includes moving to a cooler location, providing water, removing excess clothing, and seeking medical attention if necessary
Ice Roads and Ice Thickness
- As a vehicle travels on ice, it creates a resonance wave in the underlying water, affecting the strength of the ice and potentially causing a blowout or ice failure.
- The speed limit on ice roads is 25 km/h for a loaded vehicle and 35 km/h for an empty vehicle, unless otherwise posted.
Ice Thickness and Clear Blue Lake Ice
- No specific notes for this section, as it appears to be a blank table.
Hypothermia and Water Immersion
- Factors that increase the risk of hypothermia include inadequate clothing, alcohol or drugs, wetness, exhaustion, dehydration, lack of nutrition, wind, and water.
- The expected survival time for a person in cold water depends on the water temperature, with survival times ranging from 15 minutes to indefinitely.
Hypothermia Severity
- Mild hypothermia: no specific symptoms mentioned.
- Moderate hypothermia: no specific symptoms mentioned.
- Severe hypothermia: no specific symptoms mentioned.
H.E.L.P. (Cold-Related Injuries)
- H.E.L.P. stands for Heat Escape Lessening Position.
- Cold-related injuries can occur from exposure to extreme cold or contact with extremely cold objects.
- Mild cases of cold-related injuries may involve inflammation of the skin, accompanied by slight pain.
- Severe cases of cold-related injuries may involve tissue damage without pain.
- Prolonged and repeated exposure to cold air temperatures can also cause cold-related injuries.
- Affected skin may turn white and feel numb, especially in areas such as ear lobes, noses, cheeks, fingers, or toes.
