MFRI Site Ops (Rope Rescue) 2024/2025 test with Correct Solutions

MFRI Site Ops (Rope Rescue) 2024 test with Correct Solutions High-angle environment - Answer -A very steep environment in which the load is predominantly supported by the rope rescue system. belayer - Answer -The rescuer who operates the belay system Rope access - Answer -A set of techniques where ropes and specialised hardware are used as the primary means of providing access and support to workers single rope technique (SRT) - Answer -Ascending or descending directly on the rope without direct aid from contact with the rock walls or structure Rope Rescue - Answer -Rescue in high angle and steep slope environment where the use of rope and related equipment is necessary. Carabiner - Answer -Metal load bearing connectors with a self closing gate used to join elements of a high angle rope system UIAA - Answer -Union of International Alpine associations CEN - Answer -European committee of standardisation ASTM International - Answer -Formerly, American Society for Testing and Materials seat harness - Answer -A system of nylon or polyester webbing that wraps and supports the pelvic region to attach the wearer to the rope Class II Harness - Answer -A harness meant for heavy duty work by one person or in rescue situations in which another person's weight may be added Class III Harness - Answer -A full body harness meant for fall protection and rescue where inversion may occur Suspension trauma - Answer -If a potentially fatal condition that can occur when a person hangs motionless in a seat harness for a long period Emergency Seat Harness - Answer -A temporary tied harness used when others aren't available. AKA hasty harness Dynamic Rope - Answer -Rope designed to stretch under load, reducing the shock of impact after a fall.Abrasion - Answer -The damaging wear on rope and other equipment caused by rubbing against a brace of material General-Use Rope - Answer -N FPA classification for rope intended for general use where higher loads or a greater safety are needed Low stretch rope - Answer -Type of rope designed to be used in applications such as rescue repelling and descending in which high stretch would be a disadvantage and no falls or very short falls are expected Kernmantle Rope - Answer -Rope that consists of a protective shield (mantle) over the load-bearing core strands (kern). Static rope - Answer -Rope designed not to stretch under load. Used in application such as rescue repelling and ascending in which high or moderate stretch would be a disadvantage tensile strength - Answer -A measurement of the greatest lengthwise stress under slow pull conditions that a rope can resist Laid Rope - Answer -Rope made by twisting 3 or more strands together. Plain or Hawser laid ropes at 3 strands. Shroud laid ropes have 4 strands System safety ratio - Answer -The ratio between the maximum load expected on a system and its breaking strength. Load ratio - Answer -The ratio of the components meant of embraking strength to the anticipated load - Answer -Life safety rope - Answer -Broken tended to support people during rescue fire fighting or other emergency operations Moderate elongation laid life saving rope - Answer -Rope dedicated for the purpose of supporting people during rescue at firefighting operations with greater elongation than static or low stretch ropes Minimum breaking strength - Answer -The result of subtracting 3 standard deviations from the mean result of the lot being tested Kevlar - Answer -Rope material made from aramid fibre. High tensil strength low elongation and high resistance to heat. polyester - Answer -Manufactured fibre often found in the core of very low stretch static ropes. Also known as dacron Nylon 6 - Answer -Nylon used in rope manufacturing because of its shock absorbing qualities. Also known as perlon Nylon 6,6 - Answer -Type of nylon used in rope manufacturing. Resistant to wear and reduced elevation under loadNFPA 1983 - Answer -NFPA standard on life safety rope and equipment for emergency services HMPE - Answer -Is high modulous polyethelene.
