Emergency Escape Sets: Types and Maintenance
Types of Emergency Escape Sets
Emergency escape sets are crucial for quick evacuation in hazardous gas environments. There are two main types:
- Hooded Type: Designed for ease of use without requiring a clean-shaven face or the removal of glasses.
- Face Mask Type: Requires a clean-shaven face and provides a tighter fit, with some models featuring a long demand valve for extended air supply.
Specialized sets include:
- Extended Duration Sets: Lasting up to 15 minutes, used in environments like large sewer systems.
- 20-Minute Sets: Utilized for tasks requiring prolonged protection.
Maintenance Checks for Emergency Escape Sets
Regular maintenance ensures the reliability of emergency escape sets. Follow these steps:
- Check Gauge: Ensure the gauge indicates sufficient air (in the green).
- Handle and Cylinder: Unclip the handle and inspect the cylinder for any signs of damage, ensuring it is within its valid testing period.
- Hose Inspection: Pass the hose through your hands to check for cuts or wear.
- Inspect Hood or Mask: Verify the condition of the hood or mask, ensuring no damage that could compromise seal.
- Clean and Prepare: Clean the interior of the hood or mask to remove debris and reassemble securely.
By conducting these checks, emergency escape sets remain ready for immediate use in critical situations.
