Egress System Design

An Egress system refers to an access point for emergency egress and/or evacuation in buildings where handicapped persons and/or aged people may need assistance exiting buildings. An Egress system is not just an easy way to gain access to emergency exits; it’s a life saver for everyone on the site. It provides rapid entry and exit for people with disabilities. An Egress system is sometimes also referred to as a stair lift.

Egress window systems are usually a combination of a Wall, Window Well, Flat, or Grate. They are often used in retrofits of existing buildings that were not built for handicapped accessibility. The secret behind how egress systems operate is their ability to be capable of opening from inside the house in the event of an emergency and have a waiting patient be able to quickly enter into the building to receive medical assistance as needed. They use two-way electronic doors that open automatically when an access point is reached. These doors also have the advantage of being able to open in reverse as well as in a 360 degree rotation. All of these features provide excellent protection to people trying to get out of buildings.

As with any Egress system there must be a proper channel for emergency egress communications equipment. Most manufacturers recommend that the equipment is installed within three feet of the actual door. Some manufacturers go up to six feet. For purposes of aircraft-oxygen-related emergency egress systems, the recommended safety distance is three to six feet per aisle.

Additionally, this emergency egress system (10) also includes an information panel that is used to control communication between the patient and the attending emergency medical technician or the EMT supervisor. This panel can also be used to initiate or reject medical transport. The information panel also serves as a secondary locking system to prevent unauthorized entry into the aircraft.

All persons who will be working on this system need to understand the installation requirements. All persons who will be installing the electronic communications equipment need to be certified by either the National Association of Information Technology Examiners (NAITE) or the American Registry of Professional Builders (ARB). Both of these organizations are responsible for setting the licensing standards for persons involved in emergency egress and other electronics installations.

Some of the limitations of these emergency systems include: aircraft egress systems have a weight limit for support on a single aisle. Egress is controlled by manually opening and closing the emergency door. A safety belt may be required. Additionally, the aircraft glass door cannot be bypassed. These systems cannot be installed where a safety perimeter needs to be around the door.

The cost of these emergency systems will vary according to the size and the type of system included. These cost factors include: installation/installation costs, labor costs, material costs, and any equipment costs. These cost factors should be considered when purchasing emergency systems and when considering different options. Some of the commercial air ambulance companies offer the glass door system along with other types of medical transportation systems. It is recommended that you contact your chosen air ambulance company to discuss your options.

There are some governmental regulations and rules associated with emergency egress systems and their installation. The American Society of Clinical Pathologists (ASCP) recommends the installation of emergency exit and emergency egress systems. The American Heart Association also recommends the installation of emergency exit and emergency egress systems for patients who are bed ridden or otherwise unable to assist themselves. It is important to ensure that the system is certified by the appropriate regulatory agency.
