Hazard Assessment for Dispersing Substances

In plain language

If you use your drone to spray or disperse any chemicals or substances (such as fire-fighting foam), you must evaluate the risks and potential harm those substances could cause to people or property.

Requirement as structured

The CAA states that operators using unmanned aircraft to disperse chemicals or other substances must identify and assess the potential hazards, risks, and effects of those substances on people or property.

Original regulatory text

Note: Like traditional aircraft, UA can be used to disperse other types of chemicals, e.g. fire-fighting foam. Operators need to be aware of the potential hazards and risks of all substances they plan to disperse, and their potential effect on people or property.
