According to the Centers for Disease Control and Prevention’s website, when chlorine gas touches moist tissues (such as eyes, throat and lungs), it creates an acid that can harm these tissues.

Many of the chemicals are used in plastics like toys and food packaging, as well in personal care products and household items.

NIOSH, part of the Centers for Disease Control and Prevention, has a broad mandate to prevent injury, illness and death in the workplace, which touches on many industries and potential hazards.
