Three understandings: know the fire danger of the post, know the fire prevention measures and know the fire extinguishing methods.
The third meeting: I can use fire-fighting equipment, handle fire accidents and call the police.
Four abilities: the ability to find fire hazards, the ability to put out initial fires, the ability to escape in case of fire, and the ability to conduct fire education and publicity training.
The above is just the most basic. There should be examples when explaining, and you can make text, pictures and video materials.
Therefore, it is best to have the qualifications of registered safety engineer and registered fire engineer.
