PVC Signage refers to signage made from Polyvinyl Chloride (PVC), a widely used plastic known for its versatility and affordability. PVC, commonly referred to as “vinyl,” is extensively used worldwide in various applications, including signage. However, when it comes to safety signage, there are growing concerns about the environmental and health impacts associated with PVC.
The lifecycle of PVC, from production to disposal, releases toxic chlorine-based chemicals into the environment, which accumulate in water, air, and the food chain. While PVC is flame-resistant, it produces toxic hydrogen chloride gas when exposed to heat. In the event of a fire, these fumes pose a serious threat, potentially causing harm to firefighters, crew members, and passengers. The gas spreads rapidly, often more quickly than flames, trapping people and creating a life-threatening situation. Hydrogen chloride is highly corrosive and lethal when inhaled, making it a major hazard in fire situations.
Ship safety regulations, particularly those under the International Convention for the Safety of Life at Sea (SOLAS), focus on reducing fire risks, including smoke and toxic emissions. Chapter 11-2 of SOLAS addresses the dangers posed by materials that produce harmful smoke and toxic fumes when burned. While PVC is still allowed under current regulations, it is increasingly discouraged due to the severe health risks and the potential for corrosive damage during a fire. As a result, safer alternatives like Low Smoke Zero Halogen (LSOH) materials are being promoted for signage, especially in maritime environments where safety is critical.
The maritime sector is steadily shifting away from halogen-containing products like PVC as part of broader efforts to reduce environmental impact and improve safety. Research shows that PVC, when ignited, releases more smoke and toxic gases compared to safer alternatives such as polyethylene or PET materials. These alternatives produce fewer harmful substances like carbon monoxide (CO) and hydrogen chloride (HCl), making them significantly safer for use in confined spaces, such as ships. The early stages of a fire, where PVC is most dangerous, highlight the need for safer materials that minimize toxic emissions and reduce risks to human life and electronic equipment.
PET-X, a modified version of Polyethylene Terephthalate, is a type of polyester plastic priced for its strength, recyclability, and environmental friendliness. In the field of safety signage, PET-X is becoming a preferred alternative to PVC. SafeSign has pioneered the use of PET-X in signage, which offers enhanced durability, UV resistance, and fire safety compared to PVC. PET-X signage is halogen-free, reducing the risk of toxic fumes, and comes with a five-year warranty against discoloration, even when used outdoors.
PET-X signage offers several benefits over PVC signage, particularly in terms of environmental safety and compliance with fire safety regulations like SOLAS Chapter 11-2. Some key advantages of PET-X include:
SafeSign PET-X signs are photoluminescent, meaning they absorb light and glow in the dark. These signs exceed the glow requirements specified by safety standards, providing enhanced visibility in low-light conditions. This makes them ideal for emergency exits and low-location lighting systems, especially in settings like ships, where power outages or fires could obscure visibility.
