What is BS EN 340:2019?

BS EN 340:2019 is a technical standard that specifies the requirements and test methods for protective clothing against hazardous biological agents, such as bacteria, viruses, and other microorganisms. This standard ensures that protective clothing provides adequate protection to wearers, minimizing the risk of exposure to harmful biological agents.

Key Requirements of BS EN 340:2019

Protective clothing that complies with BS EN 340:2019 must meet several key requirements. Firstly, it must provide a physical barrier to prevent the penetration of hazardous biological agents. This includes tight-fitting cuffs, hems, and closures to minimize gaps between the clothing and the wearer's skin. Secondly, the material used for the clothing must resist permeation and penetration by these agents. Thirdly, the clothing should be comfortable to wear for extended periods, allowing freedom of movement without compromising protection.

Test Methods for Compliance

To determine if the protective clothing meets the requirements of BS EN 340:2019, various test methods are carried out. These tests evaluate the clothing's ability to withstand liquid penetration, aerosol filtration efficiency, resistance to tearing and puncturing, and durability after washing or sterilization. The results of these tests determine whether the clothing conforms to the standard and can provide the necessary level of protection against hazardous biological agents.

Ensuring Safety in Different Environments

Protective clothing meeting BS EN 340:2019 is crucial in a variety of environments where the risk of exposure to hazardous biological agents exists. These include laboratory settings, medical facilities, and industries working with potentially contaminated substances. By using protective clothing that complies with this standard, employers can create a safer working environment for their employees and reduce the risk of infection or contamination.
