Provides that the MTA shall not use cleaning materials or chemicals which may cause asthma or trigger or exacerbate the symptoms of asthma

This bill prohibits the Metropolitan Transportation Authority (MTA) from using cleaning chemicals that can cause asthma or worsen asthma symptoms in workers or riders. It requires the New York State Health Commissioner to create and maintain a list of banned chemicals, which the MTA must then stop using in all facility and equipment cleaning. The law directly affects MTA employees and passengers who use subway stations, trains, and buses, particularly in areas with higher asthma rates. The MTA must switch to safer alternatives within 180 days of the bill taking effect.
