What are the 4 conditions when PAPR/APR can be used instead of SCBA?
- Oxygen is above 19.5%.
- Contaminants are below IDLH levels.
- Hazard has warning properties (odor, taste, irritation).
- Proper filters/cartridges exist for the hazard.
What are the 3 conditions when SCBA is required?
- Oxygen is below 19.5%.
- Contaminants exceed IDLH levels.
- Unknown hazards or high vapor concentrations exist.
What does flame-resistant mean?
A material that self-extinguishes when ignited, will not burn continuously.
What does fire-resistant mean?
A material that withstands high heat/fire without breaking down.
Is Tychem QC 2000 flame-resistant?
No, it will ignite and burn.
Is Tychem SL 4000 flame-resistant?
No, it will ignite and burn.
Is Dräger SPC 3800 flame-resistant?
No, it will ignite and burn.
Is Tychem QC 2000 fire-resistant?
No, it has no heat or fire resistance.
Is Tychem SL 4000 fire-resistant?
No, it has no heat or fire resistance.
Is Dräger SPC 3800 fire-resistant?
No, but it has slight heat resistance (seams fail at 98°C/208°F).
Can any of these suits withstand flash fires?
No, none are designed for flash fire.
Which suit has the strongest seams?
Dräger SPC 3800 (heat-sealed seams)
Heat-sealed seams provide enhanced durability and protection.
Which suit offers the highest chemical protection?
Dräger SPC 3800 (liquid-tight, better chemical barrier)
This suit is designed to prevent liquid penetration and enhance safety against chemicals.
Which suit can be used in the most hazardous conditions?
Dräger SPC 3800, but not for vapor or flash fire risks
While it provides excellent protection, it is not suitable for environments with vapor or flash fire hazards.
What type of material is Tychem QC 2000 made from?
Lightweight polyethylene barrier for liquid splash protection.
Tychem QC 2000 is designed for limited splash protection and is suitable for certain chemical exposures.
What type of material is Tychem SL 4000 made from?
Stronger polyethylene barrier than QC 2000, better chemical protection.
Tychem SL 4000 provides enhanced resistance to a wider range of chemicals.
What type of material is Dräger SPC 3800 made from?
Tychem F fabric, high splash protection for organic & inorganic chemicals.
Tychem F is known for its durability and resistance to various hazardous materials.
Which suit has the highest tear resistance?
Dräger SPC 3800.
The high tear resistance makes it suitable for demanding applications.
What is the burst resistance of Tychem QC 2000?
68 psi.
This value indicates the pressure at which the suit may fail under stress.
What is the burst resistance of Tychem SL 4000?
71 psi.
Slightly higher than QC 2000, indicating better performance under pressure.
What is the burst resistance of Dräger SPC 3800?
35 psi
Lowest of the 3 but uses different test
But material is tougher
What type of seams does Tychem QC 2000 have?
Serged seams (least protective).
Serged seams provide basic protection but are less effective against liquid penetration.
What type of seams does Tychem SL 4000 have?
Bound seams (stronger than serged, but not vapor-tight).
Bound seams offer better structural integrity compared to serged seams.
What type of seams does Dräger SPC 3800 have?
Heat-sealed seams (fully liquid-tight).
Heat-sealed seams provide the highest level of protection against liquid exposure.
Which suit is most durable in high-abrasion environments?
Dräger SPC 3800.
Its construction allows it to withstand rigorous physical demands.
Which suit is most affected by strong acids?
Tychem QC 2000 (weakest seams).
The serged seams make it vulnerable to acid penetration.
Which suit has built-in socks for better protection?
Tychem SL 4000.
The built-in socks enhance the overall protective capability of the suit.
Which suit has multiple glove options?
Dräger SPC 3800 (SilverShield or Butyl gloves).
This versatility allows users to select gloves based on specific chemical hazards.
Which suit is certified for infectious agents?
Dräger SPC 3800 (EN 14126).
This certification indicates suitability for use in medical or hazardous environments involving infectious materials.
Which suit is certified for radioactive contamination?
Dräger SPC 3800 (EN 1073-2).
This certification ensures protection against particulate radioactive contamination.
Which suit is SOLAS-approved for maritime use?
Dräger SPC 3800.
SOLAS approval indicates compliance with safety regulations for maritime environments.
Which suit performs best in extreme cold?
Dräger SPC 3800 (flexible down to -73°C / -99°F).
Its flexibility in extreme temperatures enhances user comfort and safety.
At what temperature do Dräger SPC 3800 seams fail?
98°C / 208°F.
This temperature indicates the thermal limits of the suit’s seams.
Can any of these suits withstand prolonged heat exposure?
No, all will degrade under high heat.
It is crucial to avoid prolonged exposure to high temperatures to maintain integrity.
