Types of Disposable Protective Clothing by Protection Level (Type 1–6)

Not all disposable protective suits offer the same level of protection.
What’s the difference between Type 3 and Type 5? And when should you use each?

Let’s break down the six main protection types defined by European EN standards, so you can choose the right disposable clothing for your workplace risks.

Disposable protective clothing is classified by six main protection types (Type 1–Type 6) under European Norms (EN 943, EN 14605, EN 13982, EN 13034). Each type indicates the level and kind of barrier protection the garment offers—from gas-tight to basic splash resistance.

🔍 These types are often printed on garment labels and datasheets.
But don’t stop at the type number—understanding the real-world function of each level is the key to buying smarter.

Understanding the Types at a Glance

🧪 These types reflect design and performance testing under strict lab conditions. The higher the type, the higher the barrier.

Type 1 – Gas-Tight Protective Clothing (EN 943-1)

• Fully encapsulated suit with self-contained breathing apparatus (SCBA)
• Offers highest level of protection against gases, vapors, and liquids
• Used in hazmat emergency response, toxic chemical exposure, and industrial disasters

🔒 Example: DuPont™ Tychem® TK, Dräger CPS 7900

⚠️ Only trained personnel should wear Type 1 suits due to complexity and SCBA integration.

📌 Type 1 suits are commonly required by fire brigades, military response units, and petrochemical spill teams dealing with highly toxic substances like chlorine gas, hydrogen sulfide, or ammonia.

Type 2 – Non Gas-Tight with Positive Pressure (EN 943-1)

• Less sealed than Type 1, but maintains positive air pressure inside
• Prevents gas entry even without full encapsulation
• Often used in chemical plants for routine tasks with vapor risk

💡 Ideal for sites with known gas presence but no direct spray exposure. These suits often integrate with plant air systems and provide longer shift comfort compared to Type 1.

📦 More flexible than Type 1 but still requires air-supply compatibility.

Type 3 – Liquid-Tight Protective Clothing (EN 14605)

• Protects against high-pressure liquid jets
• Requires sealed seams and liquid-tight zippers or closures
• Suitable for jetting chemicals, decontamination, or industrial cleaning

✅ Look for: Microporous suits with welded or taped seams

🧪 Example use: Tanker discharge operators, sanitation teams

🧠 Key tip: Always ask the supplier if the seams are ultrasonically welded or stitched & taped. Stitched-only suits do not meet Type 3 compliance.

Type 4 – Spray-Tight Protective Clothing (EN 14605)

• Designed for liquid spray and saturation, but not jet pressure
• Used in pesticide application, acid transfer, industrial tank cleaning

🔄 Type 4 suits often double as chemical PPE for moderate-risk environments

🌾 Farmers spraying herbicide in windy conditions, or workers doing batch mixing of diluted acids often rely on Type 4 suits paired with gloves, boots, and face shields.

Type 5 – Dry Particle Protection (EN ISO 13982-1)

• Blocks airborne dry dusts and fibers, like asbestos or pharmaceutical powders
• Must have tight fabric weave and good closure systems
• Very common in construction, demolition, pharma packaging

🎯 Often paired with respiratory PPE in dusty work zones

📌 For best practice, combine Type 5 suits with Type FFP2/FFP3 respirators and boot covers to prevent particle transfer outside work zones.

Type 6 – Limited Splash Protection (EN 13034)

• Basic protection from light mist, fine spray, and low-volume splashes
• Used in paint shops, general cleaning, light industrial use
• Most economical and breathable suits

💡 Suited for short tasks where comfort > exposure risk

🛠️ Painters, warehouse staff, or waste sorting workers often prefer Type 6 suits for ease of movement and comfort, even if exposure to fluids is minimal.

Quick Comparison Table

🔸 = Moderate comfort depending on material (e.g., SMS, microporous)

Don’t Choose by Type Alone

Just because a suit is “Type 5/6” doesn’t mean it can handle chemical liquids or viral threats.
You must always check:

• Seam type (bound, taped, stitched)
• Fabric barrier properties
• Antistatic and flame-retardant ratings
• Chemical compatibility charts

💬 Ask suppliers:
“Has this suit been tested against my specific hazard, in my environment, at this concentration?”

📎 For example, Tyvek® 500 Xpert may be certified as Type 5/6, but it performs exceptionally well in pharma cleanrooms due to its particulate barrier and low lint shedding—despite lacking liquid-tight seams.

Conclusion

Knowing the difference between Type 1 and Type 6 is more than a technicality—it’s about choosing the right protection for the right risk.
Overprotection causes discomfort and waste. Underprotection leads to injury and liability.
