The main personal protective equipment used in case of exposure to smoke is portable breathing equipment. This is because smoke contains harmful substances and can significantly impair visibility and respiratory function. Portable breathing equipment, such as respirators or self-contained breathing apparatus (SCBA), is specifically designed to provide clean air to the user, protecting their lungs from smoke inhalation.

Other options like a smoke mask, while they can offer some degree of protection by filtering out particulates, may not be sufficient in high concentrations of smoke where breathable air is compromised. A face shield primarily protects the face from debris and splashes but does not offer respiratory protection. A full-body suit can protect against heat and some harmful particles, but without appropriate breathing apparatus, it does not adequately shield against airborne contaminants in smoke. Thus, portable breathing equipment is essential for effective respiratory protection in smoke exposure scenarios.
