Use TK555T only when the employer's site-specific hazard assessment, chemical data, respiratory-protection program, and complete PPE ensemble confirm that this suit is appropriate.
Selecting the Complete Level A Ensemble
Level A describes a complete PPE ensemble, not the suit alone. OSHA lists a positive-pressure full-face SCBA or an approved supplied-air respirator with escape SCBA, a totally encapsulating chemical protective suit, chemical-resistant gloves, and chemical-resistant outer boots among the Level A components. The SCBA, outer boots, pressure-test kit, and other task-specific equipment are not included with this listing.
DuPont lists TK555T as an encapsulating Level A design. The current TK555T technical data sheet does not list an NFPA certification. If a bid, contract, department policy, or response plan requires an NFPA-certified suit, confirm the required standard and garment style before ordering.
For lower-barrier configurations, compare the DuPont Tychem 6000 chemical coverall. Product families are not interchangeable; use the identified hazard and manufacturer data to select the garment.
Bulk Ordering and Procurement Support
Need TK555T suits for a plant, hazardous-material team, contractor, municipal department, government agency, or recurring emergency-response program? ASA, LLC supports volume quotes, purchase orders, size planning, and direct-to-site delivery for commercial and government buyers.
This is a special-order product. Confirm size, option code, current lead time, and all required ensemble components before ordering. Special-order suits are non-returnable.
Review commercial and government purchasing support, or contact ASA, LLC with the required sizes, quantity, delivery location, identified hazard, and purchasing deadline.
Safety and Selection Note
No chemical protective suit protects against every substance or exposure. DuPont reports that Tychem 10000 fabric showed at least 30 minutes of barrier protection with no observed breakthrough for 322 challenge chemicals under test conditions. That statement is not a universal safe-wear-time rating. Check the exact chemical, concentration, temperature, physical state, exposure route, task duration, seams, closures, and garment interfaces in DuPont SafeSPEC before use.
The attached socks are not outer footwear and do not provide the durability or slip resistance required for use without separate chemical-resistant outer boots. Follow DuPont inspection, pressure-testing, maintenance, storage, donning, doffing, decontamination, and retirement instructions. Do not wash a contaminated Tychem 10000 suit for reuse.
Review the DuPont TK555T technical data sheet, the DuPont encapsulated-garment user manual, and OSHA's Level A PPE guidance before selection and use.
FAQ
What is the DuPont Tychem 10000 TK555T suit?
TK555T is a rear-entry, expanded-back, encapsulating Tychem 10000 chemical protective suit designed for Level A ensembles. It is lime yellow and sold one suit per case.
Does this Level A suit include an SCBA?
No. The expanded back is designed to accommodate an SCBA worn inside the suit, but the SCBA and respiratory equipment are sold separately and must be selected under the employer's respiratory-protection program.
Are chemical boots included?
No. TK555T has attached socks with outer boot flaps. Separate chemical-resistant outer boots are required because the attached socks are not intended for use as outer footwear.
Is TK555T NFPA certified?
DuPont identifies TK555T as an encapsulating Level A design, but the current TK555T technical data sheet does not list an NFPA certification. Confirm another certified style when an NFPA standard is required by the application or purchase specification.
How do I check whether Tychem 10000 is suitable for a chemical?
Use DuPont SafeSPEC and the current permeation data for the exact chemical, concentration, temperature, and physical state. Include the complete suit design, seams, gloves, boots, respirator, exposure duration, and work conditions in the hazard assessment.
Can a Tychem 10000 Level A suit be reused?
Tychem 10000 garments are limited-use products. DuPont does not recommend washing a contaminated garment for reuse. An uncontaminated suit may be considered for hygienic cleaning and reuse only when it passes the required inspection and pressure-test procedures and remains undamaged and unaltered.
What sizes are available on this ASA listing?
The current options are M, L, XL, 2XL, 3XL, and 4XL. Fit testing should include the clothing, SCBA, outer boots, head protection, communications equipment, and other PPE that will be worn with the suit.
