Tuesday marks the 11th anniversary of the 9/11 attacks. The federal government recognizes the day as The September 11 National Day of Service and Remembrance.

Individuals, groups and employers are encouraged to engage in charitable activities and good deeds to honor the memory of the victims. Houston Mayor Annise Parker will commemorate the anniversary with a CPR event at 10 a.m. at the city's facilities located at 7125 Ardmore Street.

The day of public service will consist of Hands-Only CPR and CPR Anytime "train the trainer" sessions for more than 145 city employees. The training will be conducted by trainers from the Department of Neighborhoods, Houston Fire Department, Houston Department of Health and Human Services and other departments in partnership with the American Heart Association.

The goal is for the trainees to become trainers and educate five friends or family members on basic CPR. The training takes just 22 minutes. The all-in-one training kits contain everything needed to learn basic CPR. Effective bystander CPR administered immediately after sudden cardiac arrest can double or triple a victim’s chance of survival.

The City's 9/11 Day public service project is part of Everyone Can Be a Lifesaver, an initiative of HoustonSERVICE.org administered by the Mayor’s Volunteer Initiatives Program.
