Pre-jump equipment checks are essential for ensuring skydiving safety. However, in high humidity environments, such as tropical locations or during rainy seasons, the effects of moisture on your gear can increase the risk of malfunctions. Humidity can compromise the integrity of your equipment, so conducting thorough checks becomes even more critical.
Here's how to adapt your pre-jump gear checks in high humidity environments to ensure safety and optimal performance.
Understand the Impact of High Humidity on Gear
Humidity can affect different components of skydiving equipment in various ways:
-
Moisture can make fabrics heavier and potentially more prone to packing issues. It can also cause the fabric to absorb water, which may make it harder to deploy or result in slower inflation rates.
-
Humidity accelerates the oxidation process, leading to rust on metal parts such as D-rings, buckles, and hardware. This can reduce their effectiveness, particularly in emergency situations.
-
If you're using devices like altimeters, cameras, or communication systems, humidity can affect their battery life, performance, and potential for short circuits.
-
Moisture can cause velcro to lose its grip, and zippers can become more difficult to operate, leading to gear malfunctions when you're trying to secure or adjust your harness or main container.
Dry and Clean Your Gear Regularly
In high humidity, your gear needs to be dried and maintained properly to avoid damage:
-
Dry Before and After Use:
After every jump or training session, thoroughly dry your parachute, harness, and other equipment, especially the fabric components. Use towels or air drying systems to ensure your gear is moisture-free before packing it away.
-
Avoid Damp Storage:
Never store equipment in damp or moist areas. Ensure your gear is packed and stored in a cool, dry place. Humid storage conditions can cause materials to deteriorate faster and affect your gear's longevity.
-
Use Silica Gel Packs:
Place moisture-absorbing silica gel packets in your equipment bags or containers to help absorb any humidity that may build up during storage.
Inspect Fabric Integrity Thoroughly
The integrity of your parachute fabric is vital for deployment:
-
Check for Water Damage:
Before each jump, inspect your main canopy, reserve chute, and pilot chute for any signs of water absorption. Wet fabrics may not pack correctly, potentially delaying deployment.
-
Test Canopy Deployment Mechanism:
With high humidity, it's even more important to check the deployment mechanism. Ensure your deployment bag and pilot chute are free from any moisture or mold. If you suspect any water damage, consider packing your gear with extra attention to these components.
-
Inspect Seams and Stitching:
Humidity can weaken stitching over time. Inspect all seams to ensure there's no fraying or damage. Pay extra attention to areas where the fabric is folded or packed.
Inspect Metal Components for Corrosion
Rust and corrosion can pose significant risks to safety, especially in high-humidity areas:
-
Examine Metal Parts:
Thoroughly inspect all metal components, including buckles, D-rings, snaps, and connectors. Use a clean cloth to wipe down these parts and look for signs of rust, corrosion, or wear. Pay special attention to critical components like the automatic activation device (AAD) and closing pins.
-
Apply corrosion-resistant lubricant to metal parts where friction or wear might occur. This helps maintain the smooth operation of metal components and protects them from rust.
Test Altimeters and Electronics in Moisture-Prone Conditions
In high humidity, electronic devices may malfunction or lose accuracy:
-
Check Electronic Devices Pre-Jump:
Test all electronics---altimeters, audible alarms, and cameras---before the jump. Humidity can reduce battery life, so ensure all devices are fully charged and functioning properly.
-
Check for Fogging:
Inspect your altimeter and any other devices for signs of fogging or moisture inside the casing. If any of your devices are prone to condensation, consider investing in waterproof or moisture-resistant cases.
-
Moisture-Proof Bags for Electronics:
If you plan to carry electronics in your suit, ensure they are stored in moisture-proof bags or pouches. Even a small amount of condensation can interfere with performance, especially in critical devices like altimeters.
Perform Visual and Physical Inspections
Before each jump, perform a thorough visual and physical inspection of all equipment:
-
Harness and RSL (Reserve Static Line):
Check your harness, risers, and RSL system for any signs of wear or tear. In humid conditions, friction may cause quicker degradation, so ensure these components are secure and functioning as expected.
-
Make sure all adjustment straps are properly tightened and secured. In humid conditions, straps may loosen or become more difficult to adjust, so take extra time to ensure they're in the correct position.
-
Canopy and Deployment System:
Verify the main deployment system and reserve ripcords are functioning correctly. Humidity can cause the ripcord handle to become sticky, or the deployment bag to stick, so double-check that everything moves smoothly.
Pack with Extra Care
Proper packing is crucial, especially in high humidity environments:
-
Moisture-Free Packing Environment:
Pack your chute in a dry, shaded area away from direct sun and humidity. Moisture can get trapped in the folds of your canopy and packing materials, leading to slower deployments or potential malfunctions.
-
Use Drying Tools if Necessary:
In very high humidity, consider using special drying tools such as dehumidifiers or industrial fans to ensure all equipment, especially the canopy, is thoroughly dry before packing.
Adopt Routine Maintenance Practices
A proactive approach to maintenance can prevent issues before they arise:
-
Frequent Inspections:
Conduct routine inspections after each use, especially if your gear is exposed to high humidity for extended periods. Moisture can quickly lead to issues that are difficult to detect without regular checks.
-
Regular Professional Checks:
Have your gear professionally inspected at regular intervals. Experienced riggers can spot signs of wear and humidity-related damage that may not be obvious during casual inspections.
Conclusion
High humidity environments pose unique challenges when it comes to skydiving gear maintenance. By adapting your pre-jump equipment checks, using moisture-resistant measures, and performing routine inspections, you can minimize the risks associated with humidity. Prioritize the integrity of your equipment and make extra efforts to keep it dry, well-maintained, and ready for each jump. With the right preparation, you can safely enjoy your skydives, even in the most humid conditions.
