Where Should a Warning Optical Radiation Sign Be Used?
Industrial welding bays, UV curing stations in printing or manufacturing facilities, phototherapy treatment rooms, laser and high-intensity lamp research laboratories.

Which Material Should I Choose?
Aluminium Composite: Best for permanent indoor or outdoor signage and locations requiring a rigid, durable sign.
Correx: A lightweight, economical option for temporary or shorter-term signage.
Self-Adhesive Vinyl: Best for application directly to smooth, clean surfaces such as doors, panels and equipment housings.
PVC: A rigid, durable plastic option offering a balance between the low cost of Correx and the strength of Aluminium Composite, suitable for indoor and sheltered outdoor use.

Why this sign: It should be posted wherever equipment emits significant levels of optical radiation, such as UV lamps, arc welders, laser sources, or high-intensity discharge lighting, to alert workers and visitors before they enter the hazard zone. The sign addresses the risk of acute and chronic eye damage, including photokeratitis and retinal burns, as well as skin burns or long-term UV-related harm.

Compliance note: In Ireland, employers must provide appropriate safety signage where hazards cannot be avoided or adequately reduced by other measures, based on the workplace risk assessment, under the Safety, Health and Welfare at Work (General Application) Regulations 2007. This sign is suitable for use as part of a workplace safety-signage system where identified by that risk assessment.
