Warning lines
The warning line is a versatile and safe system. It consists of a cable or rope equipped with high-visibility flags. This warning line is used to mark off hazardous areas and access points to construction sites. This allows workers to immediately identify the safe work zone. The line must be located at least 6.5 ft (2 m) from the fall hazard.
The warning line is not a guardrail, but it allows traffic to flow in full compliance with regulations on preventing falls from heights. In addition, if a guardrail is hindering work, it can be temporarily replaced by a warning line at the problem area. The warning line is a completely modular system that can be adapted to your needs. It is durable and robust, as well as maintenance-free. It can be installed in restricted areas and on all types of flat or gently sloping roofs. It is extremely resistant to impact and temperature changes.
