Los Angeles Fire Codes on the exit
Each state has a fire codes that public and commercial building owners should observe. In Los Angeles County, all exit routes should meet some design and construction requirements. First, all exit routes should be a permanent part of that workplace. The constructors should ensure that the exit is separated from the fire resistant materials. All materials used in separating exits from the other workplace parts should have at least one hour fire resistance rating if the exit connects only three or fewer stories, but if the exit connects more than four stories, the material should have two hour fire resistance rating.
The opening to an exit should also be limited. The exit is only permitted to feature only the openings that are necessary in allowing access to exit form occupied areas of a workplace or to exit discharge. Openings to an exit should be protected by self closing doors which remains closed or which closes automatically in case of an emergency upon sounding of the fire alarm or the employee alarm system. A fire door that includes a frame should be listed or approved by the nationally recognized testing laboratory.
The number of exit points should be adequate to allow prompt evacuation of the employees and any other individual occupying the building during emergencies. The exit doors should be practically situated as far as possible from each other so that if fire or smoke blocks one exit route, people can use the other exit route. A single exit door is permitted in case the size of the building, the number of employees or the workplace arrangement is in a way that employees will be able to evacuate safely in case of an emergency.
Furthermore, all exit doors should remain unlocked. Employees should be able to unlock exit doors from the inside at all times without using keys, special knowledge or tools. Devices such as panic bars which locks from the outside are only allowed in the exit discharge doors. The doors which connect exit routes should swing out in the direction of the exit travel if more than 50 people occupy the room or if the room is located in a more hazardous area that contains elements that can rapidly burn or which can explode. The exit routes should support maximum permitted occupants in every floor served.
