Selection of explosion proof radio grade

Recently, Mr. Li from Korea found HZH MARINE GROUP and said that their LNG ship needs to be equipped with 4 explosion proof radios. I would like to ask how should we choose the corresponding level of explosion proof radios?

LNG carriers are also called LNG carriers. The main component of LNG carriers is methane, which is a flammable and explosive gas. Ordinary walkie-talkies will generate sparks during communication. If used on LNG ships, there are certain safety risks, so LNG ships must use IIA or IIB explosion-proof walkie-talkies to meet the requirements.

Entel HT544 is an Entel brand imported from the United Kingdom. Its explosion-proof grade reaches Ex ib IIA T4. This grade is called IIA grade and is suitable for methane, toluene, methyl ester, ethane, propane, acetone, acrylic acid, benzene, styrene, Carbon monoxide and other places. HT544 has passed the IECEX international explosion-proof certification, and meets the requirements of explosion-proof environment. At the same time, the waterproof level reaches IP68. It can be immersed for 4 hours at a depth of 2 meters without entering the water.
