Phillips Safety Class 3B Plastic Laser Radiation Warning Sign #28

The Phillips Safety Model 28 is fully compliant with ANSI Z136.1 and OSHA 1910.145 regulatory standards, utilizing the yellow "CAUTION" header specifically designated for Class 3B laser-controlled areas. This sign serves as a critical hazard communication tool, notifying personnel that direct beam exposure is hazardous while differentiating the risk level from higher-wattage Class 4 systems. For procurement officers, this compliance is essential for passing safety audits and maintaining institutional liability protection in surgical, research, and industrial suites. The inclusion of the universal sunburst laser symbol ensures immediate hazard recognition by all staff members, effectively preventing unauthorized entry into the Laser Controlled Area. By utilizing this standardized nomenclature, facilities ensure they meet the specific safety tier required for lasers ranging from 5mW to 500mW.

This warning sign is manufactured from 0.060" thick high-impact plastic, a substrate specifically engineered for structural rigidity and resistance to chemical degradation. Unlike adhesive-backed vinyl which can peel, curl, or harbor pathogens, this rigid plastic sign is ideal for infection control in medical environments and sterile cleanrooms. The graphics are printed with UV-stable, high-contrast inks that prevent fading under the intense LED and fluorescent lighting common in modern laboratories and hospitals. This durable construction ensures the sign survives years of manual cleaning with hospital-grade disinfectants without losing its legal legibility. For facility managers, this translates to a lower Total Cost of Ownership (TCO) by eliminating the need for frequent signage replacements due to environmental wear.

Yes, the Model 28 includes dedicated blank fields for the manual entry of specific laser wavelengths (nm) and maximum output power values. It is a technical requirement for an LSO to define these parameters at every entry point to ensure staff select protective eyewear with the correct Optical Density (OD). We recommend using a permanent industrial-grade marker to populate these fields, as the plastic surface is optimized for ink adhesion and resistance to smearing during routine sanitation. This customization allows a single sign model to be standardized across multiple departments, whether they are operating 532nm Green, 633nm Red, or 1064nm YAG Class 3B systems. Providing this precise technical data is a mandatory component of a robust and audited Laser Safety Program.

The standardized 10" x 14" format of the Phillips Safety sign is optimized to meet the visibility and legibility requirements for hazard communication in large institutional facilities. This size ensures that the "CAUTION" alert is recognizable from a safe distance, providing personnel sufficient time to halt before entering the Nominal Hazard Zone (NHZ). The high-contrast yellow, black, and white color palette is specifically calibrated for maximum conspicuousness, ensuring the notice is not overlooked among other facility placards. For safety directors, this size profile provides the necessary "conspicuity" mandated by ANSI Z535 for medium-risk hazard communication. Maintaining this size throughout a facility ensures a uniform safety culture and prevents accidental exposure to hazardous laser radiation.

Each Model 28 sign is equipped with four pre-drilled corner mounting holes to support secure and permanent installation on various surfaces including drywall, wood, or metal. This mechanical fastening method is preferred in clinical environments because 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.
