Explosion-proof walkie-talkies for hydrogen production areas
Thread Content
Hello everyone: Our company’s hydrogen production facility has been using Motorola GP328 walkie-talkies, but after an inspection it was found that they do not meet the requirements for use in hydrogen-rich environments. Therefore, we would like to ask which brands and models of walkie-talkies other companies use in such environments. Thank you!
The explosion protection rating for the GP328 is E*bⅡBT3, while the hazard class for hydrogen is ⅡC T1; the inspector should determine that it does not meet the requirements based on this.
Yes, I’d like to know what type of walkie-talkies other units are using
To be honest, the unit I know is also using a GP328.
Hytera E*bⅡC T4
Around 16,000 to 20,000 per unit for motorcycle hydrogen grades
Motorola Xir P8668EX
Hydrogen should be T4 rather than T1
