23、43 when used by firefighters, or helmets which conform to EN 443 or prEN 14052 when used by ambulance and emergency services, as the situation dictates. They are intended to provide protection against the various hazards expected to be encountered in firefighting, ambulance and emergency service dut

24、ies, except respiratory, smoke, and gas /vapour hazards. Three types of visor are described in this document. One provides protection against general hazards; the second additionally provides protection against heat and flame. The third type of visor incorporates mesh oculars, and is intended for us

25、e in very limited circumstances. This document also describes two forms for all three types of visors; face guards that provide both eye and face protection; eye guards that are shorter and effectively provide only eye protection. The requirements of this document do not apply to visors intended for

26、 use without a helmet. Such requirements are given in EN 166. Visors with corrective effect are excluded from the scope of this document. 2 Normative references The following referenced documents are indispensable for the application of this document.

This means may be an i

32、ntegral part of the helmet, may be fixed permanently or temporarily to it, or may be worn separately but at the same time as the helmet 3.2 face guard visor which provides protection to the eyes and a substantial area of the face, when in the in-use position (see 5.2.12.1) 3.3 eye guard visor which

33、provides protection to essentially only the eyes, when in the in-use position (see 5.2.12.2) 4 Classification Visors according to this document shall be classified as one of three types. Specific warning shall be included in the information provided by the manufacturer on the limitations on use of e

34、ach type (see 8 f), and the need to ensure that suitable helmet visor combinations are used (see 8 m). 4.1 General use Intended for use where there is no foreseeable exposure to significant levels of heat and / or flame. Such visors shall only be designated for use with high performance industrial s

35、afety helmets (see prEN 14052), or firefighters helmets (see EN 443). NOTE Helmets conforming to either prEN 14052 or EN 443 are considered potentially suitable for ambulance and emergency teams, where protection is required against the hazardous conditions to which such personnel may be exposed. Su

36、ch activities may include making safe search, rescue and medical intervention at disaster sites where there is no expectation of exposure to heat and flame. Where there is also expectation of exposure to significant levels of heat and flame, or for structural fire fighting, only helmets conforming t

37、o EN 443 are considered appropriate. 4.2 Firefighters use Intended for use where exposure to significant levels of heat and/or flame is foreseeable. Such visors shall only be designated for use with firefighters helmets (see EN 443). 4.3 Mesh Intended for use by emergency services where there is no

38、foreseeable need for protection against heat and/or flame, sparks, chemicals or liquid / molten materials, or electrical contact. Such visors shall only be designated for use with high performance industrial safety helmets (prEN 14052), or firefighters helmets (see EN 443). NOTE Mesh visors are incl

39、uded here specifically to cater for chainsaw use by emergency service teams during tree clearance and related activities. There will be few other situations where mesh visors can be considered suitable. EN 14458:2004 (E) 6 5 Performance requirements 5.1 General Visors conforming to this document sha

40、ll not be likely to increase the risks to the user under foreseeable conditions of use. Non-mesh visors conforming to this document shall meet the general requirements given in 5.2. Visors intended for use where there is a foreseeable risk of exposure to significant levels of heat and flame shall in

41、 addition meet the requirements of 5.3. Mesh visors shall meet the requirements of 5.4. Optional requirements are given in 5.5. Helmets used in conjunction with these visors shall continue to meet the relevant requirements of their appropriate document, with the visor in both the in-use (protective)

42、 position, and the out-of-use (standby) position. 5.2 Requirements for general use 5.2.1 Construction The visor shall be free from projections, sharp edges or other defects, which are likely to cause discomfort or injury during use. Test in accordance with 6.3. 5.2.2 Materials No parts of the visor

43、assembly, which may be in contact with the wearer shall be made of materials which, under foreseeable conditions of use, are known to be likely to cause skin irritation or any adverse effect on health. Test in accordance with 6.3. 5.2.3 Resistance to ageing Oculars shall meet the requirements of EN

44、166:2001, 7.1.5.2 when tested according to Clause 6 of EN 168:2001. 5.2.4 Cleaning and disinfection Substances and procedures recommended by the manufacturer for cleaning, maintenance or disinfection shall have no adverse effect on the exposed components of the helmet or visor, nor leave residues, w

45、hich may enhance flammability. Neither shall they be known to be likely to have any adverse effect on the wearer when applied in accordance with the manufacturers instructions. Test in accordance with 6.3. After cleaning and disinfection, the visor shall continue to meet the requirements of either 5

47、wear designated for use with the helmet/visor by the eye protector manufacturer; d) other items of PPE likely to be worn simultaneously during use. Test in accordance with 6.3 and 6.4. The test report shall identify the specific items of other PPE used during these tests. NOTE 1 Compatibility with o

48、ther items of work equipment (e.g. medical devices, thermal imaging cameras) which may be required in situations where the helmet/visor is intended to be used, cannot be explicitly included in the assessment. Such compatibilities should be assessed by potential purchasers. NOTE 2 Only frames for corrective eyewear which have been shown to be compatible with the visor / helmet should be used.
