Specification to ANSI Z136.1 and IEC 60825-1

To meet the laser safety requirements of ANSI Z136.1 and IEC 60825-1, the enclosure requires a safety Interlock® control system including appropriate warning signs - both of which are designed and manufactured by Lasermet.

Compliance to EN ISO 13849-1 (Safety of machinery - Safety-related parts of control systems)

The ICS-6 "ELISe" Interlock® Control System meets Performance Level e (PLe) of ISO 13849-1 when correctly wired.

Laser Castle modular design

The system comprises of an enclosure made from panels constructed from passive laser safety compliant material and certified to the Laser Safety Standard ANSI Z136.1 and EN IEC 60825-4. The panels are connected together (including a roof) to form the enclosure.

Manual or auto-doors

Access into the enclosure is provided by either manually-operated, or automatic, motor driven doors. The sliding mechanism provides maximum access while using minimum space. Single hinged doors are also available.

LED Signs

One of Lasermet's dual message, dual color, LED laser warning signs is installed above the door to indicate the status of the laser controlled by the ICS-6 Interlock® controller. If more than one door is installed, an LED sign is installed above each one. The LED sign, including the laser warning triangle, reads "Danger Laser On" illuminated in red when the laser is powered on, and reads "No Hazard Laser Off" illuminated in green when the laser is off. Dual language versions are also available e.g English and Spanish.

High Definition Closed Circuit TV (CCTV) monitoring system

An HD CCTV system is installed with the enclosure. Usually a single remotely controlled camera operates inside the enclosure sending video to the monitor(s) outside the enclosure. An externally mounted Pan, Tilt, Zoom (PTZ) joystick controller is used to control the High Definition camera.

Electrical system

Lasermet install the electrical wiring in containment channels inside the enclosure.


As the design is lightweight and modular, the complete enclosure can be dismantled, relocated and can be re-assembled very quickly. The standard sized panels also enable the enclosure size to be changed. This is an ideal, flexible, lightweight solution.

Control of Substances Hazardous to Health (COSHH)

Fire control

Fire can be easily put out in the early stages if quickly tackled with a water, CO2, dry powder or BCF extinguisher. (BCF Bromochlorodiflouromethane better known as Halon 1211 fire extinguisher where specified).

Smoke and Fumes

Burning panels give off carbon monoxide and styrene gas. The amount given off is less than that emitted by wood and other traditional construction materials in comparative tests. The smoke hazard of burning panels is similar to other construction or packaging material.

Cleaning Panels and Maintenance

Panels can be washed down with fresh water from a hose or a bucket. Water may be heated to 140°F (60°C). A solution of fresh water and Tepol or non-aggressive detergent can be used to remove heavy deposits, followed by a rinse of fresh water.

Laser Safety Compliance

The enclosure complies with the standards and directives shown below. The enclosure is a Class 1 Laser Safety Cabin.

  • Machinery Directive 2006/42/EC
  • EMC Directive 2004/108/EC
  • ANSI Z136.1 - Safe Use of Lasers
  • IEC 60825-4 Safety of Laser Products Part 4: Laser Guards
  • ISO 13849-1 Safety of Machinery: Safety Related Parts of Control Systems
  • IEC 60947-1 Low Voltage Switchgear and Control gear
  • IEC 61010-1 Safety Requirements for Electrical Equipment
