Types of UV Light for Different Applications

Ultraviolet (UV) radiation was discovered in 1801 when the German physicist Johann Wilhelm Ritter observed that invisible rays just beyond the violet end of the visible spectrum darkened silver chloride-soaked paper more quickly than violet light itself. He called them "oxidizing rays" to emphasize chemical reactivity and to distinguish them from "heat rays", discovered the previous year at the other end

Wastewater treatment plants are essential structures in cities and small communities. Such facilities are closely monitored by several professional institutions, such as OSHA and the NFPA. When it comes to the latter group, guidelines set forth in NFPA 820 are regulations that dictate fire hazards in such facilities. Fire related accidents in wastewater treatment facilities are uncommon. However, when they do occur, they are often catastrophic in nature due to volatile conditions in the

Mainstream, low-powered lasers that emit continuous wave beams are harmless to humans. However, there are some lasers that can cause serious damage to one’s skin and eyes. To educate and protect people from using such lasers incorrectly – in a way that could cause injury – regulatory institutions have created a classification system that establishes the level of damage that the units can inflict on humans and animals.

The main purpose of laser clas

Some high-grade lasers can damage the eye and burn the skin. Most lasers that are capable of inflicting such injuries are categorized under Class 2, Class 3 and Class 4. For example, UV lasers that emit wavelengths between 180-400nm can cause corneal damage; while some near-IR lasers, ranging between 780-1,800nm, may burn one’s retina. On the extreme end of injuries related to high-intensity lasers, exposure to specific Class 3 and Class 4 units may lead to electrical shock and bu

Commercial, recreational and industrial spaces, such as offices, construction sites and outdoor parking lots, have different lighting needs. In most cases, the activities conducted on the location dictates the type of luminaries used, brightness settings and colors of the lights.

Light color is a salient aspect of lighting systems, due to its passive contributions to productivity and clarity. Such components are measured using a Kelvin color temperature scale, with

Cleanrooms are pushing the limits of industrial manufacturing and scientific research programs. For professionals, the rooms provide a predictable environment with low levels of stray pollutants, germs, dust and chemical vapors. Activities conducted in cleanrooms are carried out with greater precision and safety.

Lumen Recommendations for Common and Industrial Work Spaces

Light brightness requirements for common and industrial spaces differ greatly. To achieve consistent, bright environments, the fixture’s luminous flux (or lumen [lm], which is the SI unit of luminous flux) must be taken into consideration. By definition, the term “luminous flux” (lx) refers to the total amount of light energy emitted from a fixture in all directions.

Electrical equipment in hazardous (classified) locations present a serious threat for workers due to the existence of explosive dust and vapors. Examples of such facilities range from grain mills and gasoline stations to aircraft hangars and chemical manufacturing plants.

To prevent devastating explosions that may occur from the ignition of combustible particles in the atmosphere, the National Electric Code (NEC) published guidelines on the proper classification of hazardous loc

Employees inside chemical manufacturing plants are exposed to some of the most unforgiving work conditions in the industrial sector. This is because in such environments, workers are exposed to extreme temperatures, dust, volatile chemicals and invisible, explosive gases.

Common protection methods against explosive risks include containment, segregation and prevention. Out of all the options, explosive containment is the only method that allows an explosion to take

Ultraviolet (UV) light can be applied to support numerous applications in a broad range of industries. In commercial paint spray booths and label manufacturing plants, UV lamps are used to streamline paint jobs and the printing of logos. Outside of such practices, the light source may also be utilized to eradicate harmful, disease-causing bacteria. Systems that rely on the light’s ability to disinfect the surrounding environment (surface and air) are mostly found in food processing plan
