Some chemical plants do not allow mobile phones; can wristbands be brought in?

Chemical plants prohibit the use of mobile phones mainly to avoid potential safety hazards caused by the batteries or wireless signals in electronic devices, such as explosions and fires. Although the bracelet has fewer functions, it still contains modules such as a battery and Bluetooth, so similar risks theoretically exist. The company may establish internal management rules in accordance with the Work Safety Law of the People’s Republic of China or relevant industry safety regulations, prohibiting the bringing of all electronic devices into high-risk areas. You can consult the company’s safety management department to learn about the specific regulations and discuss whether there are any special rules allowing the use of certain types of monitoring equipment. If your wristband truly has simple functions and is particularly important for work or health monitoring, you can try to apply for special approval or check whether there are safe and compliant alternatives available. .

It’s understandable that wearing such items isn’t allowed around major hazard sources；

A wristband can certainly be considered an intrinsically safe device. The casing of Mettler’s electronic scales can be easily pried open, and the electronic components inside are not isolated from the outside environment; a digital scale is much safer than such ones. It’s just that the bracelet hasn’t undergone safety certification: (

I’m not really sure either what the reason is for not allowing it to be brought in

Civilian electronic products that do not have explosion-proof certification must not be worn in hazardous environments such as those prone to fire and explosions.
