Phillips Safety Class 4 Plastic Laser Radiation Warning Sign #31

The Phillips Safety Model 31 is specifically engineered to meet the ANSI Z136.1 and OSHA 1910.145 "DANGER" signal word requirements for high-risk, Class 4 laser environments. This sign utilizes the mandatory red-and-black header to communicate the highest level of hazard, alerting personnel that exposure to direct or diffuse reflections could result in serious eye or skin injury. For procurement officers, this compliance is essential for passing Joint Commission or industrial safety audits and for maintaining comprehensive liability protection within the facility. The inclusion of the universal sunburst laser symbol ensures that the hazard is recognized instantly by all personnel, regardless of language barriers. By deploying this standardized signage, institutions fulfill their regulatory obligation to clearly define the boundaries of a Laser Controlled Area.

This warning sign is constructed from 0.060" thick high-impact plastic, a substrate designed for extreme durability and resistance to common clinical disinfectants. Unlike adhesive-backed vinyl, this rigid plastic will not peel, curl, or trap bacteria at the edges, making it the superior choice for infection control in surgical suites and cleanrooms. The graphics are printed with UV-stable inks to prevent the "fading" of safety colors under the intense LED and fluorescent lighting common in medical and research settings. This robust construction ensures the sign remains a permanent, professional-grade safety fixture that withstands years of manual cleaning and high-traffic exposure. For facility managers, this durability translates to a lower Total Cost of Ownership (TCO) by eliminating the need for frequent signage replacement.

To ensure full regulatory compliance, the Model 31 includes dedicated blank fields for the manual entry of specific laser wavelengths (nm), pulse duration, and maximum power output. It is a technical requirement for an LSO to provide these parameters at every entry point so that staff can verify they are wearing the correct Optical Density (OD) for their safety eyewear. We recommend using a permanent industrial-grade marker to fill these fields, as the plastic surface is optimized to keep the ink legible and resistant to smearing during routine sanitation. This customization capability allows a single sign model to be standardized across diverse departments, from dermatology clinics to high-power industrial cutting labs. Providing these precise technical details is a core component of any robust institutional safety program.

The standardized 10" x 14" dimensions of the Model 31 are optimized to meet the visibility and legibility standards required for safety signage in large facilities. This size ensures that the "DANGER" alert is visible from a distance, providing personnel with sufficient warning before they cross into the Nominal Hazard Zone (NHZ). The high-contrast color scheme is specifically calibrated for maximum conspicuousness, ensuring the notice is not lost among other institutional placards or informational signs. For safety directors, this standardized size provides the necessary "conspicuity" mandated by ANSI Z535 for high-risk hazard communication. Maintaining this size profile throughout a facility ensures a uniform safety culture and helps prevent accidental entries into high-power laser zones.

Each Model 31 sign is equipped with four pre-drilled corner mounting holes, allowing for secure and permanent installation on various surfaces like drywall, wood, or metal. This mechanical fastening method is preferred in clinical environments as it ensures the sign remains level and stable even in high-humidity areas or near high-traffic entryways. The rigid plastic construction is also compatible with industrial-strength magnetic backings or heavy-duty mounting tapes for non-destructive placement on metal cabinets or glass doors. These multiple mounting options allow the LSO to position the sign at the eye-level height required by safety standards for optimal visibility. This versatility ensures that the laser warning remains a stable and reliable component of the facility's safety infrastructure.
