Designing architectural drawings and layouts involves enormous detailing, may it be regarding structure of the project, elevations, interior fit-outs, MEP or more. One such aspect is about the safety and security – Egress and Emergency Evacuation Action plans.
Egress & Emergency Evacuation Action Plan – A legal binding
As per the international fire code section 404 and 405, facilities must have fire and safety evacuation plans. Though the standards or formulas or the way drawing calculations are done for Emergency Evacuation Action Plan differ state or nationwide, the objective remains same – life safety, hence these are also called as Life Safety Plans.
What to consider while drawing Egress & Emergency Evacuation Action Plan?
Broadly, following are the factors to consider while drawing the building designs. In some cases, there could be additional factors that is to be considered depending upon the type of project and its objective. Here is a sample list for you –
- Area & occupancy of building
- Remoteness between the doors
- Number of doors required
- Width of door (Minimum 36 inches)
- Number of exits in the building
- Minimum and maximum distance to the exit from any point of occupancy of building
- Longest distance to the exit point (shouldn’t be more than 300ft.)
- Number of staircases provided
- Width of staircases
- Floor marking & sign board towards exit points
- ADA compliant signs
Parts of Egress:
- Exit Access – Exit access is the portion of “Means of Egress” that leads to an entrance or exit
- Exit – Exit is the portion separated by all other spaces by construction or equipment that provides a protected way of travel to the exit discharge
- Exit Discharge – It’s the portion between the termination of an exit and a public way
Egress and Emergency Evacuation Action Plans can be for:
- Severe Weather
- Medical Emergencies
- Chemical Release
- Bomb Threats
Different types of buildings or situation can lead to different evacuation strategy drawing, for example, a hospital cannot have a same evacuation strategy that of a residential building, or multi-storied residential building will have a different plan than a prisoner’s cell. Let’s think about three common scenarios of an evacuation strategies here –
Defend in Place
Defend in place strategies are commonly used where the evacuation of occupants may not be the ideal first response, such as hospitals and jails. For ex – in the case of fire in a hospital, evacuation into rain or freezing temperatures could be hazardous to the health of patients. Depending on where the fire occurs, patients can be moved to a different compartment where they can be protected from smoke and fumes. Hence, while designing the project drawings for such projects, connectivity within the building needs to be focused upon.
Phased evacuations strategies may be implemented for the taller buildings. Fire departments then can evacuate the floor where a fire is located along with the two floors above and two floors below.
Full building evacuations may be necessary due to a range of incidents including natural hazards, technological events or deliberate events such as civil disturbance, bomb threats or acts of terrorism. Project drawings shall be drawn considering occupants should be able to exit or are assisted in exiting the building—ideally within less than half the duration of fire-resistance rating of the exit enclosures.
