What is emergency exit door?

Emergency exit door, also known as emergency evacuation door, security emergency door, escape door, safety exit door, emergency exit door, emergency access door, or fire exit door.

Emergency exit door, as the door of the evacuation channel, is usually 900-1500mm wide. The single door is usually 900mm, and double doors have 1200, 1400, 1500 mm, etc. Moreover, all the safe passage doors in the laboratory should be open to the outside to facilitate the emergency exit of laboratory personnel in case of accidents.

Safe passage with emergency exit door

Laboratories are places where scientific research experiments are conducted, and these places have certain differences and dangers compared to ordinary places, which are prone to explosions, fire accidents, toxic gas leaks, etc. So, in the laboratory design, we must first think of the safety issues, that is, to safety channel. The choice of emergency exit door is also important.

a. Safe passage exits should be clearly marked. The laboratory should be designed and specified in advance for emergency evacuation routes and exits, and the need to consider the reasonableness of the evacuation route and the safety of the exit. Considering the possible panic, fear, and tension in the emergency evacuation, the evacuation route, and exit signs must be visible, easy to understand, and easy to distinguish from other signs.

b. Other exits can double as emergency exits but should meet the requirements of emergency exits.

c. The emergency exit door of the room is needed to install the door lock. The door lock should be easy to open quickly inside. Laboratory interior rooms are usually not necessary to install door locks, if the need to install door locks, should be able to open in a timely manner, and shall not prevent personnel from escaping.

Safety channel with emergency door and safety color management specification

Security channel

Lines and signs can be green or yellow. Safety exit signs should be posted every twenty meters.

a. Green lane. Safety lanes, pedestrian walks, and forklifts cannot be used.

b. Yellow channel means paying attention to safety, and forklift use.

c. Red channel means people cannot pass/walk.

d. The use of dividing lines. White for ordinary areas, yellow for hazardous areas, and red for no-entry areas. The line width is not less than 100mm.

Passage and corridor size with the work area scheduled for the peak load of human flow, logistics, flow direction, and the number and size of entrances and exits.

a. Passage and corridor for human passage only, need to be based on anthropometric dimensions, taking into account factors such as dress and carrying individual equipment, the width of a single-person one-way passage should be at least 760mm.

b. The width of the double passage should be 1220 ~ 1370mm or more.

c. Channel single-side door, the width should be 1670 ~ 1830mm or more.

d. When there are doors on both sides of the channel, the width should be more than 2100 ~ 2340mm.

The layout of the power distribution device should consider the convenience of handling, installation, maintenance, operation, and testing of the equipment, in addition to the safety of the operators to prevent them from directly contacting the conductors during operation or maintenance. Therefore, the safety channel of the power distribution device shall conform to the following regulations.

a. When the distribution device is arranged in a single column, the width of the channel in front of the screen is not less than 1.5 meters.

b. When the distribution device is arranged in double rows, the width of the channel in front of the screen is not less than 2.0 meters.

c. The width of the passage behind the screen is not less than 1 meter, and can be reduced to 0.8 meters when it is difficult to meet this requirement.

Other requirements are as follows.

a. The width of the pedestrian passage is not less than 1m.

b. The width of the car and fire passage is not less than 3.5m.

c. Safety channel should be marked with a solid yellow line width, line width of 100mm, at all times to ensure unobstructed.

d. The material of regional line marking should be colored paint.

e. Area line width of 60mm, and the width should be as uniform as possible.


Entrances and exits include conventional entrances and exits, auxiliary entrances and exits, and emergency exits. The height of the entrance and exit for personnel only shall not be less than 2100mm, and the minimum width shall not be narrower than 810~860mm. Generally, the use of a threshold shall be avoided, unless it is necessary for weatherproofing.

The emergency exit with an emergency exit door should have enough space to open with one touch by hand or foot when it needs to be opened with a handle or button. The manipulation force should be less than 220N to facilitate the rapid withdrawal of the personnel inside (including those who must carry the necessary equipment or wear bloated protective clothing).

Safety color

Safety colors are the colors that convey the meaning of safety information, including red, blue, yellow, and green.

Red - various prohibition signs, traffic prohibition signs, fire equipment signs, stop buttons of machinery, brakes, and the handle of the stopping device; the exposed part of the rotating parts of the machine, such as flywheels, gears, pulleys and other spoke parts; the scale of the limit position of various tables on the indicator; various danger signal flags, etc.

Yellow - a variety of warning signs, road traffic signs, markings, cautionary markings, such as dangerous machines and cautionary lines around the pit pool; various flywheels, pulleys, and the inner walls of the shield; warning signal facilities, etc.

Blue - various instruction signs, traffic signs indicating the direction of travel of vehicles and pedestrians, such as various markings.

Green - various prompt signs, safety channels in the workshop, pedestrian and vehicle traffic signs, first aid stations and rescue stations, etc.; fire escape routes and other safety protection equipment signs; machine start-up motion buttons and safety signal flags, etc.

Contrast color

Contrast color is the contrasting color that makes the safety color more eye-catching, including black and white colors.

Black is mostly used for the text of safety signs, graphic symbols, and geometric borders of warning labels.

White is then used as the background color for safety signs red, blue, and green, and also for text and graphic symbols of safety signs.

Use of safety color and contrast color

a. Red and white stripes. Highways, traffic, and other aspects of the use of protective railings and isolation piers to indicate the prohibition of crossing; fixed prohibition of signs underneath the signpost ribbon, etc.

b. Yellow and black interlocking stripes. Various kinds of machinery in the work or move easily collision parts, such as mobile crane outreach legs, crane hook pulley side plate, the top of the lifting wall, four-wheel counterweight; flat-top trailer row barricade and side rails; door crane and gantry lower end; shearing machine compression device; punching machine scribe block and other places or settings with temporary or permanent danger.

c. Blue with white stripes. Indicative guide signs on traffic.

d. Green and white stripes. Fixed tips on the color stripes on the sign pole.

e. The width of the interphase stripes requirements. The width of the stripes between the safety color and the contrast color should be equal, that is, 50% of each.

Laboratory accident prevention measures

A. Strengthen the training of laboratory personnel

The main body of work involved in experiments is human, and human insecurity is the main reason for the occurrence of laboratory safety accidents. Therefore, only through various means improve the safety awareness and quality of laboratory personnel, in order to maximize the avoidance and reduce the occurrence of safety accidents. Experimental personnel, at least once a year receive safety training and education.

B. Building a safe environment

A good safe environment is an important factor to ensure the safety of the laboratory. To build a safe environment, we should proceed with hardware and software.

The laboratory should be equipped with perfect safety equipment and facilities, including fire-fighting equipment, alarm devices, emergency sprinklers, eye washers, first-aid kits, waste collection devices, etc. Safety channels should be checked frequently to ensure the smooth flow of safety channels and the safety of electricity and water for experiments.

At the same time, the person responsible for safety in each laboratory should be clearly identified, obvious signs should be posted for potential hazards in each laboratory, safety precautions and rules of use for various instruments and equipment should be clearly informed, and hazards of pharmaceuticals and emergency treatment measures should be clearly marked. Regular safety inspections should be conducted, strict incentives and penalties should be established, and violators must be punished.

C. Improve the safety management system

Establishing a perfect and clear system of laboratory safety management system and strictly enforcing it is an important guarantee for the sustainable development of laboratory safety work. The development of the safety management system should be in line with the reality of this laboratory, and the content covers the whole process of experiments.
