Alert workers to the presence of chemicals, combustible liquids and gases, and other hazardous materials.

Danger headers are typically used in extreme conditions to indicate an imminently hazardous situation that, if not avoided, will result in death or serious injury. Signs that meet OSHA Compliant 29 CFR 1910.145 comply with safety color standards for indicating hazards.

Apply directly onto clean, dry pipes for clear identification of contents.

ASME A13.1 requires that, for a given pipe OD, markers have a minimum character height, identify contents with a message, indicate flow direction with an arrow, and designate hazard classifications with a specific marker color. For messages with multiple marker color options, choose the color that best identifies the hazardous properties of the contents according to the ASME designations.

Style A have an alternating message; wrap them around the pipe and you can read the contents whether the arrow points left or right.

Style B have a removable arrow; apply the message to a pipe and then turn the arrow to match your system’s flow direction.

Style C have a message on one line; use with Style D or Style E to indicate flow and meet ASME A13.1.
