Natural rubber provides protection against which of the following?

1. Liquid formulations

2. Dry formulations

3. Aerosol formulations

4. All types of formulations

The correct answer is: Dry formulations

Natural rubber is known for its flexibility and resilience, particularly when it comes to chemical resistance. It has certain properties that make it effective for protecting against some types of chemicals, particularly those found in dry formulations. Dry formulations of pesticides, which are typically powdery or granular materials, can often be abrasive or have dust that can cause irritation. Rubber materials can provide a barrier that prevents these fine particles from coming into direct contact with the skin. In contrast, while natural rubber can offer limited protection against liquid and aerosol formulations, it may not provide the same level of effectiveness as it does with dry formulations. This is due to the potential for chemical penetration or degradation of rubber when exposed to certain solvents found in liquids and aerosols. Therefore, while natural rubber does provide a measure of protection, it is particularly noted for its efficacy against dry formulations due to its resistance to dust and powder particles.
