Mining is a high-risk, high-stakes job. With dangers ranging from volatile substances to heavy machinery, miners must be aware of safety protocols and mining safety signs and symbols to avoid dangerous or deadly accidents.
The Importance of Mining Safety Signs and Symbols
Signs and symbols communicate important messages at a glance using images and colors. They help create a safe work environment by providing crucial information, directing miners to follow best practices, and giving guidance during emergencies. Both newcomers and seasoned miners should understand these communication symbols to work more safely and securely. The Occupational Safety and Health Administration mandates certain signage, and mine companies may also opt for additional indicators to promote safety.
Mining Safety Signs
Color Coding of Mining Signs
Colors are crucial tools in signage. The most common colors used on mine symbols and signs are red, blue, yellow, and green.
The color red normally symbolizes danger and is used for fire-related warnings, emergency stop buttons and anywhere miners should direct their immediate attention.
Blue is generally used for informational signs and can show the locations of bathrooms, emergency exits, or first aid stations.
Yellow signs warn of potential hazards, such as falling objects, areas under construction, dangerous gases, or slippery surfaces.
The color green is often used for exit routes and emergency assembly points, and may also show the location of safety equipment or safety information.
The Meaning of Common Mining Signs and Symbols
These standard mining safety signs and symbols must be posted to quickly alert workers as to dangers and requirements and promote safety in the mining industry.
Hard Hat Symbol
A worker using a hard hat shows up when miners need to use protective headgear in a certain area.
Foot Protection Symbol
The image of a boot indicates the need in a certain area to wear appropriate footwear, for example, steel-toed boots. This is to prevent injuries such as crushed feet.
Ear Protection Symbol
Earmuffs or earplugs show that noise levels are harmful to hearing health and workers should use ear protection to avoid hearing damage.
Eye Protection Symbol
This generally consists of eye goggles or glasses and is a reminder for miners to use eye protection where there may be a risk of chemicals or flying debris that could damage their vision.
Respirator Symbol
The respirator symbol indicates the possible presence of vapors, gasses, or dust and that miners should use respiratory protection to avoid inhaling hazardous substances.
Hazard Symbol
The universal hazard symbol can appear on mining signage to warn people about possible radioactive radon gas, or open shafts and tunnels.
Emergency Exit Symbol
This sign generally uses an arrow symbol that points the way toward emergency exits in the mine.
High Voltage Symbol
Another of the essential mining safety signs and symbols workers should know is the high voltage symbol. This lightning bolt warns of high voltage equipment where workers should exercise extreme caution or use special equipment and follow correct safety procedures to avoid being shocked or killed by electrical equipment.
No Entry Symbol
A circle with a diagonal slash through it means access to the area is restricted to authorized personnel only due to possible hazards. Some no-entry symbols simply say “When light flashing do not enter mine” and have a set of lights installed nearby. Others may have a stop sign symbol and warn people not to enter the active mining area.
Blast Warning Symbol
This sign uses words to explain how many horns will sound before the explosion. It may have a green strip that says “Safety Instructions”. Yellow signs with a symbol of an explosion may also be used to signify blast zones.
Mine Signals Sign
Generally, this sign is red, but it can also be green. It outlines the number of bells that will chime to lower men, hoist men, turn on and off steam and air, and other actions. It also indicates how many bell sounds are used as a signal for danger. This keeps workers on the same page as far as communication. Mines can be a labyrinth and workers often must rely on sounds to communicate.
Pedestrian Area Sign
Often yellow, this sign warns that pedestrians often use the area.
Quarry Face Symbol
An image of a hillside with falling rocks warns people and workers to stay away from the quarry face, where falling debris could do serious damage to people and vehicles.
Abandoned Mine Signs
Just as safety signs are critical for active mines, no trespassing signs and warnings about mine hazards such as gases and lack of oxygen will encourage people to keep out.
Correctly Interpreting Mining Safety Signs and Symbols
There are several things that employers can do to help ensure that mine workers can quickly and easily interpret a mining safety sign.
Training
The first step in helping employees to stay safe using signage is to train them in it. All workers should be trained on the meaning of every sign used, and it’s never a bad idea to do refresher courses.
Consistency
Keeping signs consistent is another key way to ensure that workers can easily understand them. Although mines often span large areas, using the same signs and symbols across the entire operation can help avoid confusion and accidents.
Multilingual Signs
A mine may have a diverse workforce, so it can be helpful to use multilingual signage to ensure all workers have equal access and communication when it comes to safety.
Visibility
Because mining often happens at night or underground, it’s important to illuminate safety signs so that everyone can easily see them.
Technological Advances With Mining Safety Signs and Symbols
Some mines have begun to adapt and use technology in their signage to enhance workplace safety. For example, some mines now use electronic displays to convey real-time warnings and information relevant to their workers. Displays may warn about increases in gas levels, possible collapses, or other emergencies as they happen. This gets the word out faster so workers can respond and take action more quickly.
Where To Find Compliant Mining Safety Signs and Symbols
OSHA sets regulations for mining safety signs and symbols to best protect mine workers and help keep work environments safe. The best place to find OSHA-compliant signs is at ComplianceSigns.com.
