If you missed the free first aid trainings offered by the D.C. government over the summer, you’ve got another chance to pick up some a basic lifesaving skill.

The Golden Triangle Business Improvement District is sponsoring a training of hands-only CPR, which teaches people to administer compressions to the beat of “Stayin’ Alive,” on Friday. They are partnering with the D.C. Fire and EMS Department in the hopes of teaching at least 200 people the skills.

According to the the BID, “communities that have focused on CPR training and early defibrillation experience survival rates for victims between 40-65 percent.” And September is National Preparedness Month, after all.

“We encourage everyone to take part in this training,” said Dr. Jullette Saussy, medical director of the D.C. Fire and EMS Department. “Most people who experience cardiac arrest at home, work or in a public location die because they don’t receive immediate CPR from someone on the scene. Bystanders will never know when they may need to administer CPR,”

The 20-minute sessions are free and open to anyone who walks up (if you plan to bring a large group, though they ask you to email ppowell@goldentriangledc.com). They’ll take palce from 10 a.m.-3 p.m. in Farragut Park at Connecticut Avenue and K Street NW.
