Flameproof designs typically feature threading rather than insertable components. Class C devices provide longer flameproof surfaces and narrower explosion gaps. Hidrogeno, acetileno, and carbon disulfide necessitate the use of IIC class, whereas other substances are adequately served by IIB class.
