High altitude safety
The
summit of Mauna Kea is located at 14,000 feet. At this elevation, the
atmospheric pressure is about 40% less than at sea level. This poses
significant health hazards. The effects on humans range from a minor
discomfort to life threatening conditions. It is very important to
understand the symptoms of altitude sickness and to be familiar with
the procedures to adopt both to prevent it and to respond to it.
Please take some time to carefully read the Mauna Kea Hazards information sheet (page1, page2).
JAC
policy is to err on the side of safety when dealing with actual or
potential mountain sickness. Visitors or staff experiencing symptoms
should inform the Telescope System Specialist or Work Leader at once. A
decision will then be taken on whether the individual should descend
from altitude.
In any case, nobody is allowed to spend more than 14 hours above HP during any consecutive 24 hours period. Considering the time it takes to drive from HP to the summit
and back, this corresponds to less than 13 hours at the summit. TSSs
will enforce this if necessary by switching the telescope off!
TSSs have the JAC's full
support in this.
Please
inform the TSS if you are experiencing any of the signs or symptoms
listed below, or if you have any other reason of concern.
Minor Symptoms
mild shortness of breath
dizziness
lightheadedness
headaches
a change in visual activity
palpitations
chest tightness
nausea
Major Symptoms
shortness of breath
sudden onset of severe unrelenting headaches
chest pain
abdominal pain
|
Major Signs
slurred speech
visual disturbance
loss of coordination
paralysis
seizures
collapse
slow or rapid heart beat
labored breathing
unrelenting nausea or vomiting
|
Preventing high-altitude sickness:
- Avoid over-exertion and pace yourself
- Drink plenty of water
- Avoid standing for long periods of time
- Don't smoke
- Avoid gas-producing food
- Avoid alcohol. Note that alcohol consumption is prohibited at the summit
- Pressure breathing (slow exhale through your mouth with your lips almost closed)
The visit to the summit is not allowed if:
- you are below 16 years of age
- you are pregnant
- you have been scuba diving in the 24 hours preceding the visit
You are advised not to go to the summit if:
- you suffer from a respiratory or heart condition
- you suffer from a severe overweight condition
Other hazards:
- Dehydration can occur easily.
- Serious sunburn and eye damage can occur easily, especially if snow is present.
