Safety Eyewear Guidance
Jul
For each risk, high performance protection adapted to your industry.
Assessment of occupational risks involves identifying, assessing and ranking risks in the workplace to implement relevant preventive measures.
It is the initial step in occupational health and safety.
It is vital to check that the risk identified, the directives of the standard and the markings on the product all match.
THERMAL RISK
The thermal risk occurs when liquids or hot solids are splashed or intense radiation is emitted.
Bollé Safety has developed safety glasses, which comply with current standards, for protection against thermal risks.
Practical examples:
Radiant heat coming from ovens, splashes of molten metal or hot solids, etc.
Thermal risk is defined as: splashes of hot liquids, intense heat radiation.
MECHANICAL RISK
The mechanical risk mainly occurs during machining operations when sharp-edged particles or those with high kinetic energy are projected.
To protect you against mechanical risks, Bollé Safety has developed a wide range of safety eyewear, including safety glasses, safety goggles and safety face shields.
Practical examples:
Metal chips, shards or particles coming from tools, etc.
The mechanical risk is defined as: shocks, flying chips or solid particles.
To choose between safety glasses, safety goggles and safety face shields, the type and extent of the risk must be known:
• for a turning operation, safety glasses may be sufficient.
• for cutting work, a face screen is essential to protect the eyes and face.
RISKS LINKED TO OPTICAL RADIATION:
Optical radiation is present in many activities in industrial, medical or commercial fields.
Welding, steel works and surgical processes are all concerned.
Over-exposure of the eyes to high intensity sources can cause burns and lesions of the eye.
Bollé Safety has developed safety glasses, safety goggles, safety face shields and welding helmets to protect against optical radiation.
Practical examples:
Invisible UV radiation, visible and invisible IR radiation, etc.
The risk linked to radiation is defined as: ultraviolet, infrared, visible light, gas welding, electrical welding, laser.
CHEMICAL RISK
The chemical risk occurs when a substance projected or present in the environment reacts with the components of the eye or the skin and it appears in most industrial sectors.
This risk is particularly present in the medical field, the agri-food industry or in waste management, where micro-organisms are likely to contaminate individuals.
To prevent any risk of chemical splashes, Bollé Safety offers a wide range of safety goggles for protection against chemical and biological risks.
Practical examples:
Dust, aerosols, liquids, gas or vapours.
Chemical risk is defined as: projections of hazardous liquids, toxic dust, gas, toxic vapours.
ELECTRIC RISK
Eye protection against short-circuit electric arcs must be safety face shields only. It must not have exposed metal parts and all the outer edges of the protection must be rounded, chamfered or otherwise treated so that there are no sharp edges.
The consequences of electric shock can be cornea burns, retinal lesions and conjunctivitis.
Practical examples:
Arc eye, electric arcs
WAVELENGTHS
Wavelengths are the basis of how we perceive the world around us and two organs enable us to receive them – eyes for light and ears for sound.
Gamma rays: very dangerous and can permeate cement and even lead. They destroy cells in living organisms.
X-rays: on the other hand, can also go through our body’s tissue but are stopped by our bones – this is why radiography is possible.
Ultraviolet rays: which come from the sun, are partially blocked by the ozone layer surrounding the Earth. Those that pass through that delight sunbathers but over-exposure can be very damaging.
Infrared rays: are emitted by all warm objects. These rays are not visible but their heat can be detected.
Radio waves: are used to transmit sounds, images and digital data. The human eye is not able to identify the various elements of a ray – it only sees the result. It can only see wavelengths that measure between 380 and 780 nanometres – this is known as the ‘visible spectrum’.
