Apple has decided to ban two possibly hazardous chemicals from the final assembly of its iPhones and iPads to protect factory workers.
Apple announced the decision on Wednesday, five months after China Labor Watch and others petitioned Apple to stop using benzene and n-hexane in its iPhone production, according to the Associated Press. Despite an investigation at 22 factories that yielded no evidence that the chemicals were dangerous to workers, Apple has decided to make its suppliers stop using the chemicals and test to make sure the chemicals aren't present in its other materials.
Benzene is a carcinogen that can cause leukemia if not handled properly and n-hexane has been linked to nerve damage. The substances are often found in solvents used to clean machinery and electronics.
Apple will still be using the chemicals in the first phases of production, but will be lowering the amount of the chemicals as a whole in its devices.
