Our high visibility yellow mechanical warning signs comply with the standard design for all warning signs, comprising a yellow triangle with a black border and black graphics. These familiar, bright yellow signs always indicate potential hazards.

UK Health and Safety regulations require business owners to use safety signs "Where there is a significant risk to health and safety that has not been avoided or controlled by the methods required under other relevant law, provided the use of a sign can help reduce the risk."

Our great value range of mechanical warning signs are suitable for use in a wide range of premises, from factories to farms, garages to warehouses. Use these signs to protect your staff and visitors against unexpected or possibly unseen potential risks, from fork lift trucks to exhaust fumes, high sound levels to high voltage.

You’ll also find signs combining messages, such as our ‘High Voltage Keep Locked’ sign, ensuring risks are minimised as much as possible.

You don't need to risk your budget with our mechanical warning signs either, since all have a high voltage discount of up to 47% off usual prices.
