Identify potential ignition sources which are effective or can become effective in normal operation, in the case of expected malfunctions and in the case of rare malfunctions.

If effective ignition sources are identified, apply the appropriate requirements for at least EPL Ga or Da of one of the standards for the specific types of ignition protection.

If no single type of ignition protection is suitable to provide protection for EPL Ga or Da, it will be necessary to employ simultaneously two independent types of protection, each of them suitable for EPL Gb or Db.

Which 2 would you choose?

Ex h, c, b, k, d, p, t or …?

Keep up good work!
