Safety signs and stickers do quiet, important work. They warn about hazards, point people toward exits and fire extinguishers, mark restricted areas and remind everyone of the rules that keep a shop, garage, warehouse or job site safe. Choosing the right ones is mostly about understanding the categories, matching the message to the hazard and making sure the sign is big and bright enough to be noticed.
This guide explains the main types of safety signs, how to choose sizes and placements, and how to keep signs readable over time. It is general guidance. Always check the regulations and standards that cover your workplace.
Understand the signal words
Most hazard signs use a signal word at the top. Danger, usually shown in red, indicates a hazard that will cause death or serious injury if not avoided. Warning, usually orange, indicates a hazard that could cause death or serious injury. Caution, usually yellow, indicates a hazard that could cause minor or moderate injury. Notice, usually blue, gives information that is important but not directly hazard-related. Using the right signal word keeps the message credible. If every sign says Danger, people stop paying attention.
Common categories of safety signs
- Danger and warning signs for electrical, chemical and machinery hazards.
- Fire safety signs marking extinguishers, alarms and hose locations.
- Emergency and exit signs that guide people out quickly.
- Authorized personnel and restricted area signs.
- Chemical and biohazard labels for storage areas.
- Capacity, wheel chock and equipment-specific labels.
Our safety signs collection includes all of these, with specialized ranges such as danger signs and stickers and fire alarm signs and stickers.
Walk the space and list the hazards
The best way to choose signs is to walk through the space with a notepad. Note every hazard, every piece of safety equipment and every place where people need direction. Look at electrical panels, chemical storage, compressed gas, machinery, forklift routes, loading docks, exits and first aid stations. For each, write down the message that needs to be communicated and who needs to see it. That list becomes your shopping list.
Choosing the right size
A sign must be readable from the distance at which someone needs to act. A label on a machine control can be small because the operator is close. A sign at the entrance to a restricted area or above an exit must be read from across the room. As a general guide, larger text and simple symbols are better for longer distances. When in doubt, choose the larger size.
Signs versus stickers
Rigid signs suit walls, doors and posts. Stickers and labels suit machines, equipment, cabinets, vehicles and anything curved or portable. Many workplaces use both: a large wall sign at the entrance to a chemical storage area and smaller labels on each cabinet inside. Stickers are also useful for marking company vehicles and trailers with load, capacity or caution information.
Placement that people actually notice
Place signs at eye level where possible, near the hazard but far enough ahead that people have time to react. Avoid clutter. A wall covered with a dozen signs is harder to read than one with three well-chosen ones. Keep signs clear of obstructions such as shelving, stacked boxes or doors that swing open over them. Check that lighting is adequate, and consider reflective materials in dim or outdoor areas.
Keeping signs readable
Faded, dirty or damaged signs lose their authority. Include signs in your regular safety inspections. Wipe them clean with mild soap and water, replace any that are faded, scratched or peeling, and update them whenever a hazard, process or layout changes. Outdoor signs face sun and weather, so check them more often.
Signs for home garages and hobby shops
Safety signs are not just for large workplaces. Home garages, hobby workshops and sheds benefit from a few well-placed labels: a fire extinguisher sign, a warning on a compressor or power tool area, and a no-smoking sign near fuel or paint storage. They are a simple way to remind family members and visitors to take care.

Frequently asked questions
What is the difference between Danger, Warning and Caution?
Danger signs mark hazards that will cause death or serious injury, Warning signs mark hazards that could cause death or serious injury, and Caution signs mark hazards that could cause minor or moderate injury. Using the right word keeps signs credible.
Should I use a sign or a sticker?
Use rigid signs for walls, doors and posts, and stickers or labels for machines, cabinets, vehicles and portable equipment. Many workplaces use both.
How big should a safety sign be?
Big enough to read from the distance at which someone needs to act. Signs at room entrances and exits need to be larger than labels on machine controls.
How often should safety signs be replaced?
Check signs during regular safety inspections and replace any that are faded, scratched, peeling or out of date. Outdoor signs usually need attention more often.
Are safety signs useful at home?
Yes. A fire extinguisher sign, a warning near power tools and a no-smoking sign near fuel or paint storage are simple ways to keep a home garage or workshop safer.
Where can I check which signs are required?
Regulations vary by location and industry. Check the workplace safety standards and local codes for your area, and use signs to support, not replace, proper safety practices.
Do safety stickers work on vehicles and trailers?
Yes. Capacity, wheel chock, caution and hazard stickers are commonly used on trucks, trailers, carts and forklifts. Choose sizes that can be read from where people stand, and keep them clean so road grime does not hide the message.
What colors should safety signs use?
Follow the conventional colors: red for danger and fire equipment, orange for warning, yellow for caution, blue for notice and green for safety and first aid. Consistent colors help people recognize the message instantly.
