Level A And MT94 Flashcards
What is breakthrough time?
Time for a chemical to permeate a suit’s material to a detectable level.
Breakthrough time is crucial for understanding the protection duration of a suit against hazardous chemicals.
Why is breakthrough time important?
Determines how long a suit protects against hazardous chemicals.
Longer breakthrough times indicate better protection.
What is the breakthrough time for One Suit Flash 2?
Varies by chemical; meets NFPA 1991-2016 high-level resistance.
Specific details depend on the chemical in question.
What is the breakthrough time for MT94?
> 480 minutes for most chemicals, >720 minutes for VX/mustard gas, but only 43 minutes for HF gas.
These times illustrate the varying effectiveness against different substances.
How long can the MT94 suit be stored?
Up to 10 years if unused and undamaged.
Proper storage conditions are essential for maintaining suit integrity.
What is Pyroman testing?
A thermal manikin test that simulates a flash fire to measure burn injury risk.
This testing helps evaluate the suit’s performance in real-world fire scenarios.
How does Pyroman testing work?
Suit is placed on a sensor-equipped mannequin, exposed to flames for 3-8 seconds, then checked for burns.
This method allows for an accurate assessment of burn risk.
What is the fire resistance rating for One Suit Flash 2?
Certified to NFPA 1991-2016, with optional chemical flash fire escape protection.
About 8 seconds
This certification indicates its reliability in hazardous situations.
What is the fire resistance rating for MT94?
Withstands 3 seconds of flash fire but not fireproof—not rated for firefighting.
Users must be cautious as the suit is not designed for direct flame contact.
What is the NFPA 1991 flash fire test?
Suit is placed in a sealed chamber with propane, ignited for 6-8 seconds, then checked for airtight integrity.
This test evaluates the suit’s ability to protect against flash fire.
What must an NFPA 1991 suit show after flash testing?
No burns, no after-flame, airtight integrity, and full visual acuity retention.
These criteria ensure the suit’s effectiveness and safety.
How does One Suit Flash 2 differ from MT94?
Encapsulating polymer vs. fabric-based, flash fire escape-rated vs. limited fire resistance, liquefied gas protection vs. none.
These differences influence the choice of suit based on specific needs.
What are the pros of One Suit Flash 2?
- High chemical/biological protection
- Flash fire escape-rated
- Liquefied gas protection
- Durable polymer construction
These features make it suitable for hazardous environments.
What are the cons of One Suit Flash 2?
- Bulky
- Heavy
- Limits mobility
Users may find it challenging to maneuver in this suit.
What are the pros of MT94?
- More mobility
- Multi-threat use
- Durable and reusable
- Configurable options (pockets, MOLLE, ventilated trim)
These advantages cater to various operational needs.
What are the cons of MT94?
- Not vapor-tight
- Only limited flash fire protection
- Not ideal for high vapor exposure
These limitations are critical for users in high-risk environments.
What material is One Suit Flash 2 made from?
Single-layer polymer barrier, lightweight, chemical and vapor-tight.
What material is MT94 made from?
GORE® CHEMPAK® Ultra Barrier Fabric, designed for CBRN threats.
Which suit provides the highest chemical protection?
One Suit Flash 2 – fully encapsulating with NFPA 1991 certification.
Which suit is best for tactical or EOD operations?
MT94 – designed for mobility and multi-threat use.
Which suit is best for high vapor exposure?
One Suit Flash 2 – full vapor-tight protection.
Is MT94 vapor-tight?
No, it protects against high concentrations of liquids and gases but is not fully vapor-tight.
What kind of seams does One Suit Flash 2 have?
Welded and sealed seams for complete vapor-tight integrity.
What kind of seams does MT94 have?
Sewn and taped seams, durable but not fully vapor-tight.
