Safety Guards

What is a Plastic Safety Guard?

A plastic safety guard is a device or protective barrier designed to prevent accidents, injuries, or unwanted or accidental contact with a hazard. Safety guards are used in various settings, such as machinery, conveying and drive systems, as well as hazardous chemical areas.

Benefits of Plastic Safety Guards vs sheet metal or mesh guards

  • Lightweight – easy to install and remove. 
  • Chemical and corrosion resistance – won’t rust, and in the case of the Polystone 300 yellow guards, have extremely high chemical resistance, as well as not requiring repainting or maintenance. 
  • See though – The Palsun UV2 and Palsun AR clear polycarbonate guards are completely see through opposed to steel mesh guards that only provide an obstructed view. 
  • Strong & Durable – Due to the high impact strength of these materials, they are suitable for repeated & high impact loading. Palsun is even used in ballistic applications. 
  • Electrically Insulating – plastic safety guards can also protect against electrical shock as they will not conduct electricity. 
  • Weather and UV Resistant – Both Palsun UV2 and Polystone 300 Yellow are UV stable, therefore can be used in outdoor applications.

MATERIAL SELECTION CONSIDERATIONS

Material selection is a critical consideration when choosing a plastic for safety guards. The material must meet the needs of the application.
Visibility
Is there a requirement for a see through guard so operators and inspect or operate equipment in a safe manner.
Chemical Resistance
Will the guard be exposed to chemicals or cleaning agents that could affect the integrity of the guard, either visually or mechanically.
Temperature
The surrounding temperature for both short- and long-term exposure is important, as materials can withstand higher temperatures for short term periods compared to long term or constant exposure.
Regulatory Requirements
Does the application have regulatory requirements such as being highly visible. This is normally where Polystone 300 Yellow is used, as it will maintain the colour, unlike a painted sheet metal guard.
Installation
Since materials have some unique behaviours that relate to the success of the installation, taking this into consideration is paramount. These include thermal expansion rates and fixing holes and methods.
