SAFETY GLASSES TO USE WITH LEISURE
- Comfortable to use
- Easy cleaning
- Safety glasses made of durable and flexible nylon frame.
- Ideal for protection for laser and pulsed intense light equipment;
- Light and safe assembly.
Protected area covered: Eyes
The eyes are one of the most sensitive parts of the body where accidents can reach the greatest severity. The use of goggles when using laser systems is essential as well as having adequate wavelength protection. Damage caused to the eyes by the rays by the laser rays is irreversible and may cause partial or total loss of vision. How to avoid this irreparable damage is easy and affordable: wear the goggles !!
The glasses are an EPI
EPI is the acronym for Personal Protective Equipment. An EPI is any equipment intended to be for protection against one or more hazards that may threaten safety or health at work / activity.
The glasses, in general, allow:
- Personal protection against risks MECHANICS: Ulized in grinding activities, with projections of particles, metal burrs or waste from tools.
- Personal protection against risks OTIC / RADIATION / PHYSICIANS: Protection against toxic dust, aerosols, hazardous liquids, toxic gas or vapors
- Personal protection against electrical hazards ELECTRICAL: Protection against direct contact with electrical sources and short-circuited arcs
- Personal protection against risk THERMAL: Splashes of liquid or hot solids, intense heat radiation, heat radiation from furnaces
- Personal protection against hazards CHEMICALS: Protection against toxic dust, aerosols, hazardous liquids, toxic gas or vapors These glasses, due to their function of laser protection, are included in optical / physical protection.
Safety in the use of laser
In a procedure in which laser beams are used, such as those used in aesthetics, several safety conditions must be taken into account:
- The entrance of people in the room must be prohibited during the procedure
- There should be a sign on the entrance to inform you not to enter the room during the procedure.
- Check the operating conditions of the equipment.
- Perform preventive maintenance procedures.
- Position the patient properly.
- In environments where there are laser-emitting equipment, there should be a signaling to warn of the risks to which operator and patient are subjected.
Among these actions are:
- Warnings: warnings must be placed on the doors of the room where the laser is installed and on the device itself, preventing direct and / or invisible radiations.
- Eye protection: Laser use requires strict eye protection because of the risk of injury or irreversible scarring of the cornea and sclera. Professionals and patients should wear safety goggles specific to laser power. Care should be taken not only for direct exposure to the laser but also for indirect exposure through reflective surfaces. The laser can be reflected through metal surfaces (mirrors or reflecting glasses).
- Operative field: The skin should be cleaned before treatment with non-alcoholic solutions such as saline solution. Wet compresses should be placed on the periphery of the operative field to avoid injury.
- Particle Inhalation: Smoke caused by tissue vaporization may contain HPV, HIV, other viruses and cell particles that can be inhaled by the operator. Smoke extractors and masks with special filters are required to reduce the risk of aspiration of these materials.
- Electrical hazards: electrical hazards may also occur, appliances should be connected without extensions, in specific networks using voltage stabilizers.
Risk Classes for Laser Equipment
Lasers can be grouped into four areas according to their potential to cause biological damage. Each laser must have a label with one of the four classes described below:
- Class I: do not emit radiation with dangerous levels.
- Class IA: Special designation applied only to "not-to-be-seen" lasers, such as a supermarket's laser price reader. The upper limit of energy of Class I.A. is 4 mW.
- Class II: Visible low energy lasers emitting above Class I levels but with radiant energy not exceeding 1 mW. The idea is that the reaction of aversion to the bright light innate in humans will protect the person.
- Class IIIA: Intermediate energy lasers (continuous: 1-5 mW) and are only dangerous when looking in the direction of lightning. Most laser pointers fit into this class.
- Class IIIB: are the lasers of moderate energy.
- Class IV: composed of high energy lasers (continuous: 500 mW, pulsed: 10 J / cm2 or diffuse reflection limit). They are dangerous for vision in all circumstances (directly or diffusely spread) and present a probable fire risk and risk to the skin. Significant control measures are required in installations containing Class IV laser.
Brief historical review
The laser was developed in 1960 by an American physicist called Maiman and from there, after its development and improvement, the laser allowed a great advance in medical procedures and revolutionized therapeutic techniques. The use in dermatology is vast and assists in the treatment of many aesthetic dysfunctions.
Lasers are devices that generate electromagnetic radiation - REM (wave that propagates itself in the space resulting from the interaction of electric and magnetic fields). The elementary unit of REM is the photon, which is both wave and particle. Light is generated by stimulated emission emission of radiation that is based on the cascade of the stimulation of atoms at rest and the generation of new identical photons.
Characteristics of the different types of leisure
Laser light has its own specific characteristics: coherence (they are in phase in time and in space, aligned with each other); monochromaticity (same wavelength and same color); collimation (same direction); high intensity.
And that the laser is composed of three essential components: laser means (active medium where the stimulated emission of radiation occurs); (electric current, light from a flash lamp or other laser) and reflecting mirrors (where a small part of the light generated inside the lamp passes through).
Active laser means
The active means of the laser can be: solid, liquid or gaseous. The laser can be sent to the tissue in a pulsed fashion (in regular interrupted pulses) or continuous (uninterrupted).
The action of the laser varies in function:
- of the wavelength;
- pulse duration;
- target type and depth
- interaction between the light emitted by the laser and the determined target.
The chromophore is a group of atoms that give color to a substance and absorb light with a specific wavelength in the spectrum of the visible. In the case of hair, the chromophore is melanin.
Selective photothermolysis of the hair follicle
The use of laser for epilation is based on the phenomenon of selective photothermolysis, that is, absorption of light of a certain wavelength by the desired target, the hair follicle. Light, upon reaching the skin, penetrates the dermis and goes through the heating denature the proteins of the follicle, leading to its destruction.
Different equipment used in epilation
Among the various appliances can be used for hair removal are: long wrist ruby (694nm); alexandrite long pulse (755nm); long pulse diode (810nm); Nd: YAG of long pulse (1064nm); Q-switched Nd: YAG (1064nm) and pulsed intense light (IPL). Choosing the right laser for each type of hair and skin color and learning how to use the equipment correctly is essential to obtaining the best results.
