A few times I have been told that people are using a piece of cloth to cover windows when they are using a laser. They believe that since the window is blocked to light that a laser beam will not pass through. This is NOT a true statement! This would be similar to saying, "I'm wearing a coat, so a bullet can't go through". In order to protect yourself from a bullet, you need o bulletproof vest or bulletproof windows. If you want to protect yourself, your staff, and visitors from a laser beam, you need certified laser protective materials. Most Class 4 and many Class 3B lasers present an eye hazard over very long distances. Therefore, it is imperative to have comprehensive laser safety protection in place wherever they are present. Ordinary curtains are rarely capable of stopping a laser beam and specially designed blocking products are required. Lasers are often added to a Healthcare Program without adequate window safety/protection. As a result, this puts the healthcare facility, its workers, patients, and visitors at significant risk of laser injury. Laser blocking blinds are a simple way to cover a window. They are relatively easy to install and easy to clean. The blinds can be mounted around the frame of the window, or they can be mounted inside a recessed area. The operation of the blind is controlled by a chain (most common) or crank handle. We also offer motorized blinds that can be controlled wirelessly. The blind is built into a white finish aluminum frame, which encapsulates the top, both edges, and bottom of the blind. This eliminates the possibility of laser beams passing around the sides of the blind, blocks out direct light, and provides a neat finish. The material used in the blinds is CE marked and certified to EN 60825-4 (Safety of Laser Products Part 4: Laser Guards). It is vital that the roller blinds are certified and the material has been tested to the relevant laser safety standards. If non-compliant material were to be used - for example - untested, uncertified sun-blocking material, this may have the potential to allow laser beams to penetrate the blind and consequently may cause harm to personnel and/or equipment.

Another option is having a more robust structure made of aluminum profiles. Eye bolts could be connected to the top, and then moved with a hoist. Alternatively, you could move it with a forklift. We are not limited to laser safety enclosures. We also provide acoustic, cutting, modular, splash, and automotive enclosures to name a few. When you need an enclosure for your new laser, please give us a call at 770-332-0092. Getting started is simple. We will have you fill out an enclosure worksheet. After that is filled out, we will have an initial call before we provide a quote.

Laser Barriers range in size from a small window to a full enclosure that can encompass large airplane components. What do you need for your laser setup? Here are some things to consider when you are shopping for a laser barrier system. If you are operating a laser in an environment where only trained laser professionals have access to the room, then you may simply need a curtain to cover the window(s) or a movable barrier with castors. Curtains don't have to hang from a curtain rod. They can be attached to a surface with Velcro or magnets. This laser batter is easy to remove and store if needed If you are using a laser in a laboratory, then a curtain with a track may be the best option. The tracks can be straight, u shaped, or rectangular to section off a portion of a laboratory or room Laser enclosures are useful for robotic laser systems and can be made per the customer's needs. The enclosure can have doors, windows, and even a mezzanine (as seen in the picture below). All containment systems - whether industrial laser enclosures, assembly line laser enclosures, welding enclosures or other types of integrated automatic enclosures - can be outfitted with a laser interlock system to ensure safe personnel access via enclosure doors, windows, and equipment hatches Laser blinds can be used to cover windows and create a laser barrier These have either a chain or crank handle. Motorized blinds are also available. These can be wireless or dry contact. Wireless blinds can be triggered to go up and down all at the same time if they are in the same room These are custom made to fit the dimensions of your window. They can be installed inside the frame or outside the frame of the window Still not sure what laser barrier would work best for you? Contact us and we will provide you with the best option based on your application. Call us at 770.332.0092 or email us at contact@rtlasersafety.com. We look forward to hearing from you!

Safety signs are found in almost every area in office buildings and large facilities. Why are these signs important? They are informational and can also protect you, your staff, and visitors from hazards. For instance, our LED signs can be connected to an X-Ray machine. When the X-Ray machine is in use, the sign will light up in red and read "Danger X-Ray On". Therefore, this will inform personnel that the X-Ray is in use and they should take precautions. There are many uses for LED signs. I will discuss a few ways to select LED warning signs below. Ultra Signs Recently, we had a customer who had a need for a sign. They required a message to have both an English and Japanese message on the same sign so all of their workers could read it. We were up for the challenge and it was a great success! Now, all employees will be aware of when access is allowed and when a mission is in progress. This sign is an Ultra 790 three-state sign. It has two messages, one in green, and one in red Messages are in both English and Japanese The Ultra sign comes in three sizes: The Ultra 470 is 18.5" (w) x 7" (h) x 1" (d) The Ultra 790 is 31.1" (w) x 7" (h) x 1" (d) The Ultra 580 is 22.8" (w) 7" (h) x 1" (d) - The 580 is Waterproof! Mini LED Signs Our Mini signs are a great option for just about anywhere. For example, Holland America line uses this LED sign for Engine Control Room and Bridge entrances. They used the three state sign with ECR and Bridge Open/Closed messages. Another interesting application is confessionals! The sign is placed outside of the confessional and alerts parishioners if it is occupied. The uses are limitless - bathrooms, laboratories, industrial applications, medical facilities, etc. The dimensions for the sign are 6.3" (w) x 4.3" (h) x 1.5" (d) Slim Jim LED Signs Need a sign that is EASY to install?

Laser Blocking Blinds are suitable for many applications involving the use of lasers. For example, use cases can be found in the Healthcare market - specially in patient operating rooms, ambulatory centers, and dentist / doctor offices. Our laser blocking blinds create a safe barrier between the laser and other supporting staff, patients, or visitors who may walk by. The blinds/shades are easy to install and aesthetically pleasing to the work environment. To clarify, the roller blind is built into a white finish aluminum frame. The frame encapsulates the top, and both edges of the laser blocking material. This sealed barrier eliminates any possibility of laser beams passing around the sides of the blind. The barrier also blocks our direct light (not blackout) and proves optimal safety and protection. The blinds are operated (changing of up/down position) by several methods: Chain (most common) Crank Handle Motorized (Dry Contact Switch or Wireless Remote Control) Blind installation is relatively easy. Therefore, maintenance or contracted installers can install the blinds. In addition, we provide installation instructions that can be downloaded from our website. However, should you run into problems while installing the blinds, our staff can provide immediate assistance. Laser Blocking blinds are manufactures based on the dimensions of your windows. Simply measure the size of the window opening (width by height) of the opening and forward them to us for a custom price quote. Lead time and delivery are typically around 3 weeks. Also, the blinds come with a 12-month limited warranty. Laser blocking window blinds do not require regular maintenance, as they can be cleaned with soapy water (mild detergent). Products such as Hlorsept (or equivalent) can be used. To clarify, abrasive cleaning materials must NOT be used. They can cause damage to the blind material. Most importantly, the blinds meet the following compliance standards: ASTM International ASTM E84 Standard Test Method for Surface Burning Characteristics of Building Material Conformite Europeene (CE) CE Marked International Electrotechnical Commission (IEC) EN AW-6060 En 60285-4 Safety Laser Products - Part 4; Laser Guards National Fire Protection Association (NFPA) NFPA 701-2015 Test Method 1 - Flame Propagation NFPA 92-503 - Electric Burner Test Lasers are often added to a Healthcare Program without adequate window safety/protection. As a result, this puts the healthcare facility, its workers, patients, and visitors at significant risk of laser injury.

Yes! Not only does eyewear protect your patient from the laser, but it also protects them from other objects and liquids that could make contact with their eyes. When patients sit in the chair, they can be exposed to so many things that could injure the head, neck, and eyes. Even a handpiece could cause irreversible damage. With a rotation speed of 180,000 to 500,000 times per minute, handpieces could project particles at speeds up to 50 miles per hour. Chemicals, pieces of old filing materials, prophy paste containing silica, or even broken bur could fly into a patient's eye. Eyewear is an inexpensive way to protect you, your staff, and your patients. Laser Protective eyewear is used in Medical, Military, Research, Education, and Industrial laser applications. The use of lasers in medical and industrial is advancing, thus, your laser protection must also advance. Laser safety eyewear protects eyes from hazardous reflected or scattered laser light. Getting the perfect eyewear for your laser is easy. Simply send us the spec of your laser, and we will be able to provide you with a quote. We offer eyewear that fits over your regular prescription glasses as well.

Laser (Interlock) Control Systems are a method of ensuring that dangerous (class 3 and 4) lasers are contained. Interlock systems, with proper implementation, will limit the laser access to qualified, trained individuals. The interlock system prevents harm to those who are not properly trained on the safe use and operation of a laser. Laser control systems can range from simple to complex configurations. Here are a few of the basic parts that are needed to get started. 1. ICS-6 Interlock Controller This is the brain of the operation. This versatile unit can control laser interlocks, door locks, illuminated warning signs and other equipment. The ICS-6 can operate beam shutters and laser power with feedback monitoring and fault detection. The controller interfaces with Access Control and Fire Detection Systems. The controller fits to an Override. This allows controlled access through interlocked doors while accepting emergency stop inputs. 2. Access Keypad The access keypad (ICS-KP-14) is used with the ICS-6 interlock controller for the purpose of inhibiting access to a hazardous area by unauthorized persons. The keypad is mounted outside a door which is electronically locked and monitored by the interlock system. It also has two outputs that activate for a set time when the correct 4-digit code is entered: The override output and door unlock output. Each output illuminates a corresponding indication on the keypad when activated. 3. Laser Beam Shutters To prevent damage to eyes or equipment, laser beam shutters are used. To clarify, shutters stop the laser beam automatically during unauthorized access, or manually when the beam is not required. Our shutters are gravity fed for fail-safe operation. Shutters have a remote switching option and are also compatible with safety control systems. 4. Door Interlock Switches Switches monitor the position of the door, window, or access panel (open or closed). You can use them to shut off power, control personnel access, and prevent a laser from starting (or turns it off) when the door is open. 5. Warning Lights Automated switching of single or dual message signs. Frequently used with laser control systems are the LEDS-L-2W and the LEDS-ULT-470-L-2W. These signs run off of 24V and connect directly to the ICS-6 Controller. When the laser is in use, the sign will read in red "Danger Laser On". When the laser is off, the sign will read in green "No Hazard Laser Off". 6. Emergency Stops Emergency stop buttons connect to the ICS-6. Once pushed, this immediately halts the laser in case of emergency. Example of Interlock System Layout In conclusion, those are the basics of a laser control / interlock system. If you have an area you need to interlock, you can simply fill out our interlock design form and we can provide you with a quote. Above all, please contact us with any questions at 770.332.0092 or contact@rtlasersafety.com

Laser users should be aware of the risks involved with their equipment. Not all lasers present the same hazards. Proper understanding and training of the particular laser being used, and its dangers, is necessary to avoid injury. Laser with visible beams are categorized into four classes. Class 2 These relatively weak lasers are not a skin or burn hazard. They do not cause eye damage unless someone stares directly at the beam. Class 3R These low powered lasers are not a skin or burn hazard. Laser protective eyewear is generally not necessary. Class 3B These lasers are not a skin or burn hazard. Laser protective eyewear appropriate for the beam's power and wavelength is recommended. Class 4 These lasers can burn skin and cause permanent scarring. some types of material will burn. Laser protective eyewear is essential. Infrared lasers, used commonly in industrial settings, pose invisible risks to the user. The eyes cannot detect infrared, so they must always be protected from exposure. Federal Codes and Regulation (CFR) in the US and IEC codes internationally define laser classes and impost required safety regulations. They mandate manufacturer warning labels and outline specific safety measures for laser operators. American National Standards Institute (ANSI) provides control measures for laser hazards in the US. For example, ANSI Z136.3 provides guidance for the safe use of lasers in health care. ANSI Z136.9 provides standard policies of safe use of lasers in manufacturing environments. EN is the European standard. Certified Laser Safety Officers (CLSO) ensure that compliance with all standards is being met. They can recommend appropriate laser safety eyewear and signage that warns that lasers are in use. Window coverings, such as laser curtains, blinds, or shutters must be in place to prevent laser radiation from escaping through the glass.

High powered lasers are frequently used in industrial applications. Their widest use is in the processing of materials including cutting, drilling, and welding. New applications are being developed all the time. In addition, laser processing can be controlled by computers. Lasers make it possible to effectively cut or drill through materials that are either too brittle or too pliable to be worked with contact tools. Laser welding applications fuse materials together. Higher intensities are generally required to heat and melt the materials. Laser Hazards Lasers must be used to protect against potential hazards to employees. The type of laser, the wavelength at which it operates, and the application being used are factors that determine appropriate safety measures. Exposure to laser radiation can damage eyes and skin. Other laser hazards in the workplace include toxic fumes, chemical spills, and laser produced fires. The occupational safety and health administration (OSHA) publishes specific guidelines for laser usage in the workplace. Laser Safety Laser safety enclosures are required to provide safety in many industrial environments. Controls are required at the entryway to the laser controlled area. Interlocks and protective housings must cover the equipment or the path of the beam. Barriers and curtains must be designed to withstand the intensity of the laser beam. RT Technologies Laser Safety Enclosures RTT provides laser containment systems for industrial users. Tabletop enclosures, assembly line configurations, and room size robotic laser enclosures are available. They provide UV, near infra-red, far infra-red, and visible light protection. All our laser containment systems can be outfitted with laser interlock systems to ensure safe personnel access via enclosure doors, windows, and equipment hatches. Optional closed circuit monitoring systems are available. Design, manufacturing, and installation of our enclosures are supervised by a Staff Certified Laser Safety Officer (CLSO). Our products are FDA/CHRH certified to ANSI and EN specifications. RT Technologies Services Additional RTT laser safety products include laser warning signs, WiFi mobile camera, and a full line of laser protective eyewear.

The audio alert system is a local public address system that audibly delivers a pre-programmed message when triggered. The message is heard from a speaker integrated into the compact unit, which is triggered - either by switching the unit on (by applying 24 VDC), or by movement being detected by a passive infrared detector built into the unit. The audible warning device is contained in a professionally styled, attractive wall mounted unit, and can act as a local public address PA system where it can do the job of an announcer of audible warning messages, providing an acoustic warning to complement visual warning signs. The provision of a talking message enables the loudspeaker feature to be incorporated into hospitals, offices, engineering establishments, doctors or dentists waiting rooms, or other internal environments where audible information is required. The speaking message can be up to 40 seconds long and can be set to automatically repeat as frequently or infrequently as required up to an hour. Institutions or businesses can use the automatic audio alert system as a sound generator to deliver an audible message. There is no need for a loudhailer or megaphone to audibly warn local personnel of dangers in the vicinity. Used as an audible information system - or local audio system - to enable messages, adverts, or audio messages to be delivered when required, this mini announcer, or automatic annunciator, is triggered either by power-up (24 VDC) or by movement picked up by the integrated passive infrared detector, PIR. Program your OWN voice and message with our microphone (sold separately).
