TOMAR Signaling and Lighting: Critical Safety and Process Solutions for Pharmaceutical Plants

Pharmaceutical manufacturing environments are a blend of precision, automation, and safety-critical processes. From highly controlled cleanrooms to hazardous chemical storage areas and auxiliary power stations, these facilities demand versatile and compliant signaling systems to ensure worker safety, product integrity, and operational efficiency.

TOMAR Electronics offers a full range of visual and audible signaling solutions engineered for the unique challenges of pharmaceutical operations. Whether signaling “Do Not Enter” in a sterile zone or initiating a plant-wide evacuation due to chemical release, TOMAR’s products deliver reliable, clear alerts where and when they matter most.




Engineering Integration Across Pharmaceutical Plant Systems

Pharmaceutical operations span across a wide spectrum of specialized areas—from sterile production to R&D labs and chemical prep stations. TOMAR products are designed for integration across all facility systems, including:

  • Process Control and Automation Signaling
  • Cleanroom Entry and Restricted Area Notification
  • Chemical Handling and Storage Zones
  • Plant-Wide Emergency Alert Systems
  • Water Treatment and Utility Rooms
  • On-Site Power Generation or Boiler Systems

From low-profile aesthetic indicators to explosion-proof strobes, TOMAR delivers solutions that align with both FDA manufacturing requirements and OSHA safety standards.

Process Signaling in Automated Production Environments

Modern pharmaceutical plants are highly automated, relying on precise process control for consistent production and regulatory compliance. TOMAR’s Microstack, LED Microstack, MicroLERT, and Microstrobe® products are ideal for integration with PLCs, sensors, and SCADA systems.

Common use cases include:

  • Start/stop indicators for conveyors
  • Equipment fault signaling
  • Raw material level alerts
  • Movement of mobile equipment or containment units
  • Production status (batch complete, paused, in progress)

These stackable or surface-mounted indicators are designed for compact spaces and clean aesthetics—ensuring minimal disruption to controlled environments while providing essential visual and audible alerts.

  • Microstrobe®: Compact LED lights providing high visibility for confined or high-precision assembly areas.
  • MicroLERT: Versatile signaling devices for effective communication and safety in pharmaceutical assembly operations.
  • Microstack/Andon Lights: Stackable andon lights ideal for real-time monitoring and status signaling, enhancing workflow coordination and productivity.

Cleanroom and Restricted Area Visual Alerts

Access control is critical in pharmaceutical manufacturing—especially in cleanrooms and sterile R&D zones. TOMAR’s MicroLERT™ and MicroLED™ indicators provide subtle, clear visual messaging to control foot traffic and signal status changes without introducing bulky or industrial-looking equipment.

Applications include:

  • “Do Not Enter” alerts for gowning or sterile zones
  • Visual indicators for contamination risk
  • Testing or radiation zone identification
  • Access permission based on machine or test cycle

These devices are low-profile, easy to sanitize, and designed to complement high-visibility environments without adding unnecessary clutter.

Harsh Environment and Washdown Zone Applications

Manufacturing equipment in pharmaceutical plants is routinely sanitized, often with high-pressure water and corrosive cleaning agents. TOMAR’s 4375S, 4375L, 490S-T, and XL Series strobes are engineered for these environments.

These models feature:

  • IP66 or higher ingress protection
  • Corrosion-resistant housings
  • Impact-resistant lenses
  • Optional Division 2 ratings for hazardous zones

Whether placed near pill presses, blending tanks, or packaging stations, these devices ensure safe signaling even after repeated sanitation cycles.

Chemical Handling and Explosion-Proof Solutions

Pharmaceutical plants make extensive use of solvents, acids, and specialized chemicals. Areas such as chemical storage rooms, formulation labs, and waste treatment zones often fall under Division 1 or Division 2 hazardous classifications.

TOMAR provides rugged, explosion-proof signaling devices designed for these critical applications:

These devices are commonly used to communicate alerts like:

  • “Contamination Warning”
  • “No Entry – Testing in Progress”
  • “Chemical Transfer in Progress”

Engineered Safety and Compliance for Pharma Operations

Pharmaceutical manufacturing is among the most tightly regulated and high-stakes industrial sectors. Process visibility, safety signaling, and rapid incident response are mission-critical to protect workers, products, and equipment.

TOMAR Electronics provides a full suite of safety signaling solutions that offer:

  • Seamless integration with process controls
  • Cleanroom-compatible visual indicators
  • Explosion-proof and Division-rated alerts
  • High-audibility evacuation systems
  • Custom tone and color configurations

Whether you’re upgrading your contamination warning system, outfitting a new cleanroom, or modernizing your chemical zone alerts, TOMAR has a reliable, compliant solution tailored for pharmaceutical operations.

When reliability, cleanliness, and compliance are non-negotiable—TOMAR is your trusted partner for pharmaceutical signaling systems.
