Asphyxiation Hazard sign
When there is a risk of suffocation an Asphyxiation Hazard sign must be used.
This Sign is part of our Danger sign range, used to warn of the danger from lack of oxygen or from obstructions to air passages. These asphyxiation risks can be found in confined spaces (vessels, tanks, silos, boilers etc.) Breathing fine dust, such as cement can cause suffocation.
