However, this is a misunderstanding: “safe” is rather the state of being protected from recognized hazards that are likely to cause harm (3.1.2). Some level of risk is inherent in products or systems. The use of the terms “safety” and “safe” as descriptive adjectives should be avoided when they convey no useful extra information. In addition, they are likely to be misinterpreted as an assurance of freedom from risk. The recommended approach is to replace, wherever possible, the terms “safety” and “safe” with an indication of the objective. For example, use “protective helmet” instead of “safety helmet”. See also ISO/IEC Guide 51:2014, Clause 4.

[SOURCE: ISO/IEC Guide 51:2014, 3.9] 3.1.5 intended use use in accordance with information provided with a product or system, or, in the absence of such information, by generally understood patterns of usage [SOURCE: ISO/IEC Guide 51:2014, 3.6] 3.1.6 reasonably foreseeable misuse use of a product or system in a way not intended by the supplier, but which can result from readily predictable human behaviour Note 1 to entry: Readily predictable human behaviour includes the behaviour of all types of users, e.g. the elderly, children and persons with disabilities. For more information, see ISO 10377 [5] . Note 2 to entry: In the context of consumer safety (3.1.1), the term “reasonably foreseeable use” is increasingly used as a synonym for both intended use (3.1.5) and reasonably foreseeable misuse. [SOURCE: ISO/IEC Guide 51:2014, 3.7]3.1.7 blue-light hazard potential for a photochemically induced retinal injury resulting from optical radiation (3.2.1) exposure in the wavelength range 300 nm to 700 nm 3.1.8 infrared lens hazard potential for a thermal injury to the crystalline lens (and cornea) of the eye resulting from exposure to optical radiation (3.2.1) in the wavelength range 780 nm to 3 000 nm 3.1.9 retinal thermal hazard potential for a thermal retinal injury resulting from exposure to optical radiation (3.2.1) in the wavelength range 380 nm to 1 400 nm 3.1.10 ultraviolet hazard potential for acute and chronic adverse effects to the skin and eye resulting from exposure to optical radiation (3.2.1) in the wavelength range 250 nm to 400 nm3.2.2 visible radiation light any optical radiation (3.2.1) capable of causing a visual sensation directly Note 1 to entry: There are no precise limits for the spectral range of visible radiation since they depend upon the amount of radiant power (3.4.7) reaching the retina and the responsivity of the observer. The lower limit is generally taken between 360 nm and 400 nm and the upper limit between 760 nm and 830 nm. Note 2 to entry: For the purposes of standards on eye protection, the limits of the visible spectrum are usually taken to be 380 nm to 780 nm. These limits coincide with those in ISO 20473 which specifies the spectral ranges for optics and photonics standards and avoids the overlap at either end of the visible spectrum in the CIE definition. Note 3 to entry: For lasers, the visible wavelength band is defined as 400 nm to 700 nm. This is because eye protection against low-power visible lasers often relies on the eye’s aversion response, which includes the blink reflex (3.5.1.17). For this to happen, the laser beam (3.3.14) should appear very bright, hence the need to cut off the extremes of the visible band where the spectral luminous efficiency (3.4.11) of the eye is quite low.
