10/26: Floor Warden Training

Although COVID-19 has brought many new challenges in the workplace, we want to remind everyone of the importance of emergency preparedness and floor warden training at 100 First Street. Designating an emergency response team for your floor or suite is not only required, but crucial in being prepared in the case of an emergency.

We will be hosting virtual floor warden training on Monday, October 26th, from 10:00 AM – 11:30 AM. Please mark your calendars and plan to attend this training together with our team and Matt Harris, Fire Life Safety Trainer with Allied Universal. During this training, we will be covering all fire and earthquake evacuation and relocation procedures in preparation for the Annual Fire Drill. Please note that we are required by law to have a minimum of one fire drill annually and participation is obligatory.

Please contact us to register for the training.
