What is Harness Suspension Syndrome (HSS)?

When the patient remains motionless in the harness resulting in blood pooling in the legs and occlusion of veins by the harness. When a patient is rescued there is a risk that toxic pooled blood will rush to the heart causing an overload of the right ventricle.

How can you help prevent Harness Suspension Syndrome (HSS)?

Tell the Patient to continually move their legs, as well as flex their leg muscles to maintain that blood flow.

How do you treat Harness Suspension Syndrome (HSS)?

While suspended: provide high-flow oxygen and encourage them to keep moving/flexing their limbs.

When a patient is removed: remove the harness and tight clothing but never lay the patient supine. Try to keep the patient vertical as much as possible to prevent all that pressure from going to the heart

Who determines what happens first for decon at the station?

The Company Officer makes the call. If the level of exposure is minimal the apparatus and tools get priority. If firefighters have been heavily contaminated they should shower as soon as possible.

What PPE is required for decon?

Safety glasses, medical gloves, N95 (recommended but optional)

How do you clean the SCBA regulator?

pressurize the system, immerse the regulator in the Ecolab Neutral Disinfectant Cleaner, and agitate, and rinse the regulator by agitating it in the sink of clean/warm water. Finally, dry the regulator by opening the bypass valve. Make sure the regulator is thoroughly dry if dunked.

What should you use to scrub/clean fire gloves?

sponge or soft cloth, do not use a brush.

When should a traffic control plan and traffic control measures be set up when working on the highway?

When the incident will require members to be working on the scene for more than 30 minutes.

If you have to turn your back to traffic when working outside of a safe zone what must you have with you?

Another member as a lookout

Which apparatus has arrow boards?

All engines and some secondary apparatus

What are the two modes for emergency vehicles required by NFPA 1901?

1) signaling drivers/pedestrians that the apparatus is responding to a call 2) signaling other drivers that the apparatus is stopped and blocking the road.

How is the fend-off position achieved? What position is the apparatus on the roadway?

angled 20-30 degrees, and remaining at least 0.5 meters from the adjacent open lane. A traffic cone should be placed on the front corner of the apparatus.

What are the time frames for minor, intermediate, and major traffic incidents?

Minor = less than 30 mins Intermediate = 30 mins to 2 hours Major = over 24 hours

What are the 5 components of a traffic control zone?

1) Advanced Warning Area 2) Approach Area 3) Transition Area 4) Activity Area 5) Termination Area

What is the recommended distance between the apparatus and the incident site?

Approximately 4 metres for every 10km/h of posted roadway speed

When placing cones what is a tangent versus a taper?

Tangents are parallel and straight with the flow of traffic. Tapers are diagonal between lanes

What is the appropriate tangent line length for traffic cones?

For dry, straight, flat roads it's 1 metre for every 1 km/h posted (50km/h = 50 m). in wet road conditions multiply the posted speed by 1.5 for snow/ice conditions multiply posted speed by 2
