We see safety signage in various shapes and forms out and about airport operations, but what do they actually mean?
There are many different approaches to accident prevention that airline employees deal with on a daily basis in any part of an airport environment. Training, awareness and communication are major components in preventing accidents; one major form of visual awareness is signage that we see throughout airport environments.
Safety signage assists ramp agents with understanding possible hazards in any operation and what actions may need to be taken to prevent an accident. Color coding of specific signage will help us make safe decisions on how we act based on the color that is related to that specific sign. The following are some basics of safety signage, which includes physical hazard identification and accident prevention.
RED = DANGER
OSHA recommends that danger signs or tags be designed and printed in red or predominantly red, with lettering or symbols in a contrasting color.
If an immediate hazard exists, danger signage should be conspicuously displayed.
Aside from just a sign hanging around to identify a hazard, ramp agents need to be trained that danger signs indicate immediate danger and should exercise special precaution.
Red must also be included on signage that is used to identify:
- Portable containers for flammable liquids; the name of the contents also needs to be affixed to the container and clearly visible. The contents may be stenciled or painted in yellow.
- Fire protection equipment, such as fire extinguishers and fire alarms.
- Emergency shut off switches for machinery and ground service equipment.
YELLOW = CAUTION
Caution signs are used to warn against potential hazards or to caution against unsafe practices and also serve as reminders for personal protective equipment (PPE) requirements.
These signs are all yellow or predominantly yellow with lettering or symbols in a contrasting color. Caution signs and markings warn of physical hazards (striking against, slipping, falling, caught in between) and should be predominately displayed when such hazards exist.
RED-ORANGE = BIO HAZARD
The red and/or orange color on this type of signage indicates that there may be infectious substances and/or infectious waste present that may pose a risk of death, injury or illness if exposed. This signage may also come with symbols along with lettering in contrasting color.
GREEN = SAFETY INSTRUCTIONS
Green is used to designate items in operations that will assist in the event of an accident. The location of first aid equipment, such as emergency eye wash stations, emergency quick drench showers and first-aid equipment, is identified with such signage. These signs will have white or black lettering against a white background.
BLUE = NOTICE
General notice information signage may also be found around the airport environment. Although these generally do not have any impact on immediate workplace safety, they are used to communicate information to ramp agents regarding specific instructions or regulations.
Ramp agents should not only be familiar with the identification, procedures and proper use of signage, but with the color codes that are to be used for marking/identifying physical hazards and equipment.
Color coding is a standard way of quickly identifying hazards and provides guidance to avoid personal injury or equipment damage. In addition to color coding, the design of these signs should be uniform throughout the operation. This signage also needs to be visible at all times when corrective actions are about to take place or work is being completed and can be removed when the hazard no longer exists.
Ramp agents are required to receive training on signage recognition and also need to have an understanding about the warning information that is on accident prevention signs and tags. The training should include the following information:
