Visual aids, Safety Signs and Symbols tend to decrease the risk of accidents and produce consciousness of dangers in precise zones or close to certain materials.

12 Types of Safety Signs and Symbols

Identical safety signs and safety symbols are categorized by pictures, pictograms, shapes, words, phrases, sentences, or statements. Individual profiles of each sign carry a diverse meaning, and each color signifies the type of safety it defines.

1.Caution Signs and Labels

Caution Signs are designed with the purpose to warn emergency respondents. They are also used to warn the people who often go to spaces with potential hazards and encounter many regulatory requirements.

Research laboratories, Shops, and Manufacturers’ places where hazardous resources are utilized or warehoused should have standard caution signs at entrances. Major Companies upright a caution sign in a pamphlet holder above or near the room number poster with a door or block at the respective entry.

Caution Signs are a combination of all requirements for National Fire Protection Association (NFPA) 704 Hazardous Materials, biohazardous and radioactive materials authorization, entry necessities, nutrition and beverages ban, and lab exchange info.

Examples of Caution Signs include:

  • Biohazards
  • Compressed gases
  • Cryogens
  • Lead
  • Radioactive materials

2.Chemical Signs and Labels

Chemical hazards can be encountered at different workplaces. Places, where a Chemical hazard can occur, are hospitals, ranches, industrial facilities, construction sites, transportation centers, and more. Chemicals are mostly invisible making them a danger for someone who is exposed. It is difficult to identify spots where they can be and arrange containment devices with safety signs and labels.

Safety from such chemical hazards includes identifying containers, tanks, and storage areas, post PPE information, and more with symbols or adhesive labels available in many sizes and supplies. Chemical Signs are usually built with a protective laminate layer that battles moisture, scrape, UV, and chemicals

The following are two types of Chemical Safety Signs and Symbols

  • Signs for Hazard Communication
  • Informative Signs for Safety Instructions.

Examples of Chemical Safety Signs and Symbols include:

  • Explosive Chemicals
  • Flame Signs
  • Acute Health Hazard Chemicals

3.Confined Space Signs and Symbols

Confined space signs are used to recognize areas that need approved or permit entry only. Confined Spaces are not designed to accommodate any human constantly. Accordingly, they do not have sufficient ventilation, light, or comfort of exit compulsory to guarantee safety. Based on these needs Confined Space Signs are posted by the entry. They are principal to a facility’s capacity to keep its workforce and visitors safe around these risky zones.

These Safety Signs and Symbols show the essential protective equipment for confined spaces, together with gloves, eye protection, or a hearing guard. Confined space signs are accessible in many sizes and materials, with high-performance polyester, plastic, and aluminum.

Confined space also sometimes comes with text options, like “Do Not Enter.” Signs are accessible with OSHA(Occupational Safety and Health Administration)-biddable headings, signal words, and safety signs, such as the danger symbol.

Some Hazards in Confined spaces include:

  • Poor air quality
  • Toxic gases could make the worker ill or cause the worker to lose consciousness.
  • Asphyxiants –Asphyxiants are gases that can displace oxygen in the air. Asphyxiants consist of argon, nitrogen, or carbon monoxide.
  • Chemical exposures because of skin contact /ingestion/inhalation
  • Fire hazard.
  • Process-related hazards
  • Physical hazards – sound, heat/cold, radiation, vibration, electrical, and insufficient lighting.
  • Safety hazards consist of moving parts of equipment, structural hazards, engulfment, entanglement, slips, or falls.

Some examples of Confined Space Signs include:

  • Danger Confined Space Floor Sign
  • Danger: Confined Space Entry Can Be Fatal – Wall Sign
  • Warning – Confined Space Label

4.Construction Site Signs

Construction sites are very dangerous places where many types of hazards can cause accidents. Construction site signs are made to decrease the peril of accidents and injuries. They are used to protect workers and community members from injury. Construction signs are used to identify possible hazards and dangers, guiding the workers or companies to selected first aid sites and emergency equipment.

Another function of construction site signs is to guarantee site safety, by playing a vital part in the efficient day-to-day running of the location. As a result, pertinent and satisfactory construction site signs are compulsory by law. Eastern Highway offers an extensive range of construction site signs.

Flammable signs are warning signs that show the incidence of flammable gas or liquid. The term Flammable means the material can be without difficulty set on fire if exposed to a source of blast-off. Flammable materials range from spirits and fuel to paper and wood. It means that all workrooms are at risk to variable degrees.

Where there is a flammable material, it must be ensured that a flammable sign is used to help recognize it under the guidelines of Control of Substances Hazardous to Health (COSHH). Flammable signs are present on the vessel of any flammable substance. Companies should keep a flammable gas symbol on separate containers, as well as in a prominent room in the part where the flammable material is stockpiled.
