Protective coveralls are widely used across industries to protect workers from hazardous substances, particles, and liquids. However, not all protective coveralls provide the same level of protection.
Different environments require different types of protective clothing, each designed to meet specific safety standards.
This guide explains the six main types of protective coveralls (Type 1–6), their protection levels, materials, and common applications.

What Are Protective Coverall Types?
Protective coveralls are classified based on the level of protection they provide against hazardous materials.
International standards categorize protective suits into six types:
| Type | Protection Level | Typical Application |
|---|---|---|
| Type 1 | Gas-tight | Chemical plants |
| Type 2 | Non-gas-tight | Industrial environments |
| Type 3 | Liquid-tight | Chemical handling |
| Type 4 | Spray-tight | Chemical spraying |
| Type 5 | Particle protection | Dust and hazardous particles |
| Type 6 | Limited liquid splash | Light chemical protection |
Each type is tested according to specific European PPE standards.
