Properly positioned workplace safety signs help communicate hazards before personnel enter an area or begin an activity. Safety signage should complement appropriate training, engineering controls, protective equipment, and established workplace procedures.
Danger, Warning, Caution & Notice Signs
Different safety messages communicate different levels of risk and types of workplace information. Selecting the appropriate sign helps ensure that instructions are clear and easily understood.
Danger Signs
Danger signs are intended to identify particularly serious hazards where failure to follow safety instructions could result in severe injury or death.
Common applications include high-voltage electrical equipment, confined spaces, hazardous machinery, and restricted industrial operations.
Warning Signs
Warning signs communicate potentially hazardous situations that could result in serious injury. They help alert personnel to conditions requiring specific precautions.
Warning signs are useful around machinery, industrial equipment, loading areas, and other hazardous workplace locations.
Caution Signs
Caution signs identify hazards that may cause minor or moderate injuries and remind personnel to exercise appropriate care.
Examples include forklift traffic warnings, required protective equipment, and other workplace safety instructions.

Electrical Hazard and High Voltage Warning Signs

Always follow applicable electrical safety standards and facility procedures when installing and using electrical hazard signage.
Construction Site Safety Signs
Construction sites present changing hazards involving heavy equipment, electrical systems, restricted access, overhead work, material handling, and other potentially dangerous conditions.

Traffic control products help communicate instructions and manage vehicle movement around construction sites, industrial facilities, commercial properties, and temporary work areas.
Diamond Tool Store carries traffic-related products including parking identification signs, Do Not Enter signs, speed bump warnings, traffic sign covers, and Stop/Slow paddles.
Stop/Slow Paddles
Stop/Slow paddles are used by trained flaggers to communicate instructions to approaching motorists in appropriate traffic control operations.
These products are commonly associated with road construction, utility maintenance, and temporary traffic management.
Always verify that the selected paddle and traffic control arrangement meet applicable standards and project requirements.
Traffic Sign Covers
Traffic sign covers can be used in appropriate temporary traffic management situations where existing signage must be covered as part of an approved traffic control plan.
Selecting the correct traffic control accessories helps support clearer communication during construction and maintenance activities.
Aluminum, Plastic and Vinyl Safety Signs
Safety signs are available in different materials to accommodate installation requirements and environmental conditions.
Aluminum Signs
Aluminum signs provide a durable, rigid option for many outdoor and industrial applications.
They are commonly selected for parking lots, property identification, facility entrances, and locations requiring signs mounted on posts, fences, or walls.
Plastic Signs
Plastic safety signs are lightweight and suitable for many indoor workplace applications.
Common uses include machinery warnings, facility notices, exit identification, and general workplace hazard communication.
Vinyl Signs and Labels
Vinyl signs and adhesive labels are useful for compatible surfaces where a lightweight, adhesive-backed warning or instruction is preferred.
They are commonly used on equipment, doors, walls, and designated facility areas.
Before ordering, verify the product's dimensions, material, installation method, and suitability for the intended environment.
How to Choose the Right Safety Signs
Choosing the right safety sign requires more than selecting a message. The sign must also be appropriate for the location, hazard, and applicable safety requirements.
Consider the following factors:
Type of hazard: Determine whether the sign should communicate Danger, Warning, Caution, Notice, or another specific instruction.
Indoor or outdoor use: Select materials suitable for the installation environment.
Visibility: Choose dimensions, colors, and mounting positions that allow the message to be read at the necessary distance.
Material: Consider aluminum, plastic, or vinyl based on durability and installation requirements.
Regulatory requirements: Verify applicable OSHA, ANSI, MUTCD, ADA, fire code, and local requirements where relevant.
Installation location: Position signs where personnel can recognize the hazard or instruction before entering the affected area.
Maintenance: Inspect signs periodically and replace those that become damaged, faded, obstructed, or unreadable.
Appropriate safety signage helps support consistent communication and effective facility management.

What is the difference between Danger and Caution signs?
Danger signs communicate especially serious hazards that could result in death or serious injury. Caution signs are generally used for hazards that may result in minor or moderate injuries. The appropriate signal word should reflect the actual risk.
Are OSHA safety signs required in workplaces?
OSHA requires certain hazard warnings and safety signs under applicable workplace standards. The specific requirements depend on the industry, hazards, equipment, and working conditions. Not every workplace requires the same signs.
What are the best safety signs for warehouses?
Common warehouse safety signs include forklift traffic warnings, high-voltage signs, PPE requirement signs, restricted access notices, fire extinguisher signs, and emergency exit identification. Selection should be based on the facility's hazards and operating procedures.
What materials are safety signs made from?
Safety signs are commonly manufactured from aluminum, plastic, vinyl, and other materials. Aluminum is frequently selected for outdoor signage, while plastic and vinyl are often used for indoor warnings and facility identification.
Can aluminum safety signs be used outdoors?
Many aluminum safety signs are suitable for outdoor installation. However, weather resistance, reflectivity, finish, and mounting requirements vary by product. Always review the individual specifications.

An Exit sign identifies an exit route or exit location. A Not an Exit sign identifies a doorway or passage that should not be mistaken for an exit. Building codes may require illuminated exit signs or other additional identification.

Stop/Slow paddles are handheld traffic control devices used by trained flaggers to direct vehicles during appropriate temporary traffic control operations, such as road construction or utility work.
