Worldwide Standards For Chemical Protective Clothing

Choosing the right chemical protective clothing can be complex, as no single type can protect against all chemicals. Various factors such as barriers, exposure scenarios, and duration of exposure must be considered. Following established standards is crucial for frontline workers to make informed decisions. Since the mid to late 1980s, different regions have developed standards defining garment performance, testing methods, and technical documents. The three main standards for chemical protective clothing are ISO, European Regulation, and US legislation.

Standards for Chemical Protective Clothing

ISO Standard

The ISO standard, particularly ISO 16602, classifies chemical protective clothing into six types based on whole garment testing:

Type 1: Airtight Leakage Test
Type 2: Inward Leakage Test
Type 3: Jet Test
Type 4: Spray Test
Type 5: Particle Inward Leakage Test
Type 6: Low Level Spray Test

ISO 16602 also specifies performance requirements and testing methods for material properties and chemical resistance for each type.

European Regulation

The European Regulation classifies chemical protective clothing as “Category III” PPE under Regulation (EU) 2016/425, targeting high-level risks. It involves multiple standards for each performance requirement and testing method. The main garment standards include:

Type 1: EN 943-1/2
Type 3: EN 14605
Type 4: EN 14605
Type 5: EN ISO 13982-1
Type 6: EN 13034

Material requirements are detailed in EN 14325, including test methods and performance classifications. Despite some differences, the European regulations align closely with ISO 16602 in terms of garment classification and material testing.

US Legislation

The US regulation “29 CFR 1910.32” requires employers to determine appropriate PPE for workplace hazards but does not specify performance standards. OSHA and EPA guidelines categorize protective equipment into four levels (A to D), each requiring varying degrees of skin and respiratory protection:

Level A: Full encapsulation vapor-tight suit with a positive-pressure, full-face SCBA
Level B: Hooded, non-airtight chemical-resistant clothing
Level C: Full/half face mask, or (powered) air-purifying respirator
Level D: Water repellent gowns or scrubs (optional)

Additionally, several NFPA standards, such as NFPA 1991, 1992, and 1994, define performance requirements for protective clothing, primarily for emergency responders.

Overview Of Chemical Protective Clothing Standards

These standards provide a framework to ensure appropriate protection against chemical hazards. While different regions have their specific requirements, the core objective is to safeguard frontline workers. Standards from various countries, such as Brazil’s Certificate of Approval, Japan’s JIST 8115, Korea’s KOSHA certification, and Taiwan’s CNS standard, align with ISO 16602 and EU regulations.

Regardless of the standard, the primary goal remains to offer objective information to help workers choose the right chemical protective clothing, ensuring safety and occupational health. The importance of chemical protective clothing cannot be overstated, as it serves as the last line of defense against chemical injuries.
