Understanding IS 14166:2024 The New Standard for Full Face Masks by BIS

The Bureau of Indian Standards (BIS) recently introduced IS 14166:2024, a comprehensive standard for full-face masks. This milestone is part of India’s ongoing efforts to enhance occupational safety and align with global best practices. In this blog, we delve into the details of IS 14166:2024, exploring its significance, scope, technical requirements, and implications for manufacturers, employers, and end-users.

The Significance of IS 14166:2024

Full face respirator masks are critical personal protective equipment (PPE) used across industries to safeguard workers from harmful substances, airborne contaminants, and hazardous environments. The introduction of IS 14166:2024 ensures that these masks meet stringent quality, safety, and performance benchmarks. It also fosters standardization, enabling users to rely on BIS-certified masks for consistent protection.

By adopting IS 14166:2024, India strengthens its commitment to workplace safety, enhances the competitiveness of Indian manufacturers, and supports the ‘Make in India’ initiative. This standard also helps reduce the import dependency on international PPE products by ensuring that locally manufactured full face masks meet international standards.

Scope of IS 14166:2024

IS 14166:2024 applies to full-face masks designed for respiratory protection. These masks are widely used in sectors such as:

• Chemical and pharmaceutical industries
• Construction and mining
• Firefighting and emergency services
• Oil and gas operations
• Industrial painting and spray coating

The standard specifies requirements for the design, performance, testing, and marking of full face masks. It covers masks used in combination with filters, breathing apparatus, or powered air-purifying respirators (PAPR).

What is New:

1. New Parameter Introduced — Leak Tightness

The leakage of a full-face mask should not exceed the limit indicated by a pressure change of 1 mbar in 1 minute, when tested with 10 mbar negative pressure.

2. Classification (Class 1, 2, and 3) Introduced Based on Application Area:

• Class 1: Full-face masks for light-duty use
• Class 2: Full-face masks for general use
• Class 3: Full-face masks for special use

3. Inward Leakage

Two methods are used to test inward leakage:

• SF6 method
• NaCl method

A full-face mask must fit securely against the contours of the face. When tested for inward leakage, the test contaminant should not exceed an average value of 0.05% of the inhaled air for any of the ten recommended test subjects in any of the test exercises.

4. Requirement for Resistance to Thermal Radiation (Class 3 Masks)

Class 3 full-face masks must be resistant to thermal radiation. Compliance can be tested in two ways:

• The full-face mask conforms to leak tightness after a test period of 20 minutes, even if it becomes deformed.
• Visibility becomes impaired after a test period of ≥ 4 minutes, but the facepiece still conforms to leak tightness when tested after an additional one minute.

The leak tightness of the test full-face mask shall be checked before the test.

5. Facepiece Connector and Threading Requirements for Different Classes

• For Class 1 full-face masks, the connection between the facepiece and connector must withstand an axial tensile force of 250 N.
• For Class 2 and Class 3 full-face masks, the connection must withstand an axial tensile force of 500 N.

Key Features and Technical Requirements

1. Design and Construction:
   • The standard mandates a snug fit to minimize leakage.
   • Masks must feature durable materials resistant to chemical and thermal damage.
   • Transparent visors with anti-fog and impact-resistant properties are essential for clear visibility.
2. Performance Criteria:
   • The masks must effectively filter particles, gases, and vapors based on specific testing protocols.
   • They should demonstrate minimal breathing resistance, ensuring user comfort during extended wear.
   • The sealing system must maintain a reliable barrier under various environmental conditions.
3. Testing and Certification:
   • IS 14166:2024 outlines rigorous testing for filtration efficiency, airflow resistance, impact strength, and temperature resilience.
   • Manufacturers are required to undergo BIS certification to ensure compliance with the standard.
4. Marking and Instructions:
   • Masks must display clear markings, including the BIS logo, standard reference (IS 14166:2024), and product specifications.
   • User instructions for maintenance, cleaning, and storage must be included to enhance longevity and performance.

Implications for Stakeholders

1. Manufacturers: Indian manufacturers must align their production processes with IS 14166:2024 to obtain BIS certification. While this may entail initial investments in testing facilities and technology upgrades, it opens up opportunities to cater to a growing domestic and global market.
2. Employers: Employers can enhance worker safety by procuring BIS-certified full face masks. Compliance with IS 14166:2024 demonstrates a commitment to adhering to safety regulations, reducing liability, and improving workplace morale.
3. End-Users: For workers, IS 14166:2024 ensures access to reliable, high-quality masks that provide superior protection. Clear instructions and better performance metrics lead to improved user confidence and health outcomes.
