Which product types are not authorized for OC spray?

• A. Foam spray and aerosol type products are not authorized.
• B. Gel-based sprays are not authorized.
• C. Water-based sprays are not authorized.
• D. Liquid streams are not authorized.

Answer: (A)

The key idea is how the spray’s delivery form affects safety and control. Foam sprays and aerosol-type products tend to be less reliable in real use: foam can break into unpredictable blobs and cling to surfaces, while aerosols create fine mist that drifts with the wind and can expose bystanders or the user. This makes targeting and decontamination harder and increases the risk of unintended exposure. In contrast, gel-based and water-based sprays provide more predictable dispersion and safer, more controllable delivery, which is why they are commonly authorized. Therefore, identifying foam spray and aerosol-type products as not authorized best aligns with the goal of safer, more controllable OC spray use.
