Does the safety regulations contain warning slogans?

In safety standards, warnings need to be added to products if they are dangerous.

For example, functional overheated surfaces (touching of high-temperature surfaces is prohibited)

Laser (don’t stare at it)

Moving parts (can cause harm)

Battery (not allowed to be used in rain, water, humid environment, not thrown into fire, not exposed to the sun), etc. Similar warnings are included in various standards. When a product has these dangers, you need to add warnings in your instructions or on the surface of the product
