BODY PROTECTION – PROTECTIVE CLOTHINGBody protection is intended as clothing which covers the mid-section, like for example protective clothing, including vests, jackets, trousers, protective capes and aprons. Clothing which signals danger in the surrounding road area also falls into the protective clothing category. Harmonised norm UNI EN 340 "Protective clothing – General requirements" establishes essential requirements for protective clothing in reference to special norms, as for example in norm UNI EN 470 "Clothing for use in welding and allied processing." The "General Requirements" related to protective clothing supply necessary information on the subject of markings and on the manufacturer, on clothing sizes and behaviour of material upon aging.
MARKINGSProtective clothing must be provided with the following as well as with CE marking of conformity:
- name, brand name or other manufacturer or sales agent identification method
- type, business name or code
- European norm number
- pictogram related to the danger against which the clothing shall be utilised, especially the environment where it shall be used and if necessary the level of efficiency or class
- maintenance markings
- manufacturer information
All pieces of protective clothing must be accompanied by clear, written information which must include the following:
- name and full address of the manufacturer or company sales agent
- product name
- European norm number
- explanation of pictograms, levels or performance classes
- instructions for use
Clothing for protection against the cold, according to UNI EN 342
For protection against temperatures below -5° C – for example in refrigerated cells or outdoor works (during the winter months). Protective clothing utilised is made of padded fabric or with more than one layer of synthetic or natural material. Three and, respectively, four classes (performance levels) have been established for permeability against air and resistance to permeability of water vapour.
CLOTHING FOR PROTECTION AGAINST INCLEMENT WEATHER ACCORDING TO UNI EN 343In the event of unfavourable atmospheric conditions, of wind or environmental temperatures above - 5°C, protective clothing in synthetic material or plasticized material is utilised, with openings for aeration under the armpits and on the back. If used with thermal lining, the clothing for protection against inclement weather can also be useful as protective clothing against the cold for temperatures up to - 5° C
PROTECTIVE CLOTHING FOR WORK IN WELDING AND ALLIED PROCESSING ACCORDING TO UNI EN 470Protective clothing must protect users wearing them from burns due to hot or fiery metal particles and from brief contact with flames and UV radiation. Norm UNI EN 470 is valid both for protective clothing in leather and in fabric. The hot particles or welding sprays must not remain attached to the protective clothing. The reaction to fire of material utilised must respond at the very least to class 1 requirements in accordance with norms CEN 162 N 105.
PROTECTIVE CLOTHING FOR WORKERS EXPOSED TO HEAT IN THE INDUSTRIAL SECTOR, ACCORDING TO UNI EN 531
(does not include protective clothing for fire-fighters and welders)
This clothing is suggested for protection against actions of hot parts, radiant heat, brief contact with open flames and sparks such as with sprays of slag or metal liquids. Clothing for protection against heat must reflect the radiant heat and must be mainly or fully flameproof and of synthetic fibres. These are carrier materials due to their reflecting surface covering with laminates in aluminium, copper, silver and gold which reflect radiant heat up to 90%. Materials with self-extinguishing and partly acid resistant covering synthetics are utilised against flammable liquid substances.
Protective clothing requirements are established by means of performance levels represented in pictograms with 5 numbers:
limited fire diffusion:
testing in accordance with norms CEN/TC 162N126 (ex. 2).
testing in accordance with norms UNI EN 367 (ex. 3).
testing in accordance with norm UNI EN 366
sprays of liquid-aluminium metal:
testing in accordance with norms UNI EN 373 (ex. 2).
sprays of liquid-iron metal:
testing in accordance with norms UNI EN 373 (ex. 1).
REQUIREMENTS FOR PROTECTIVE CLOTHING FOR FIRE-FIGHTERS AS CONTAINED IN NORMS UNI EN 469.
CLOTHING FOR PROTECTION AGAINST CHEMICAL SUBSTANCES
Clothing, capes, aprons, sleeves and hoods must protect from liquid or solid (particle) substances and from biological substances.
Harmonised norms regarding clothing protecting against chemical substances indicate necessary requirements for utilised materials, for seams and joints, as integrated requirements of protective clothing.
The following are new EN norms regarding clothing protecting from liquid and liquid and gas chemical substances, including liquid aerosol and solid particles:
UNI EN 465 Clothing for protection against chemical substances, protection against liquid chemical substances, performance requirements, type 4 equipment, protective clothing with waterproof connections between different parts of the clothing.
UNI EN 466 Clothing for protection against chemical substances, liquid chemical substances (including liquid aerosols), performance requirements, type 3 equipment, protective clothing with waterproof connections between different parts of the clothing.
The norms establish the minimum requirements of the clothing for protection against chemical substances, with connections between parts of the clothing which are impermeable to liquids and sprays.
UNI EN 467 Clothing for protection against chemical substances, protection against liquid chemical substances, performance requirements, type 5 equipment, clothing guaranteeing protection on body parts against chemical substances.
The norm establishes minimum requirements for protective clothing material for example aprons, sleeves and hoods.
UNI EN 943 Protective clothing for use against liquid and gas chemical substances, including liquid aerosols and solid particles, performance requirements for clothing protecting against aeration with connections impermeable to gas (type 1B equipment).
The norm establishes minimum requirements for protective clothing sealed against gaseous chemicals, above which equipment for air supply is worn, which functions independently from the environmental atmosphere (for ex. a compressed air recipient). A full mask is installed in the clothing, to which respiratory protection equipment is attached.
UNI EN 944 Protective clothing for use against liquid and gaseous chemicals, including liquid aerosols and solid particles, performance requirements for protective clothing powered by compressed air, with gas-seal connections (type 1C equipment).
The norm establishes minimum requirements for gas sealed protective clothing. Air for respiration is introduced in overpressure, for ex. by means of a compressed air tube with a regulation valve.
UNI EN 945 Protective clothing for use against liquid and gaseous chemicals, including liquid aerosols and solid particles, performance requirements for protective clothing powered by compressed air with non gas-seal connections (type 2 execution).
Ventilated protective clothing air supply occurs as per protective clothing in accordance with UNI EN 944.
UNI EN 946 Protective clothing for use against liquid and gaseous chemicals, including liquid aerosols and solid particles, performance requirements for wrap protective clothing and non-aerated with gas-seal connections (type 1A execution).
Gas-seal protective clothing is utilised with respiratory protection equipment which operates independently from the surrounding atmosphere, for ex. a compressed air recipient. The respiratory protection equipment is worn underneath chemical substance protective clothing.
PROTECTIVE CLOTHING FOR ELECTRICIANS
Work on electrical systems requires the use of personal protection equipment verified in accordance with norms DIN VDE 0689, part 1. These include insulated protective devices for the head, face, hands, feet and body. Since insulated protective devices are impermeable to water vapour, they are not utilised willingly. This type of clothing must be tested with a voltage of 1000 V and must be marked specifically (see symbol).
CLOTHING FOR PROTECTION AGAINST MECHANICAL ACTIONS
Protective clothing for workplaces with present hazards of remaining entangled in mobile or rotating parts must respond to requirements contained in norms UNI EN 510. Besides one-piece clothing (work suit with or without sleeves), vests and trousers with flaps are also used. This clothing refers to tight-fitting clothing with smooth surfaces without outside pockets and with closures which open toward the outside.
CLOTHING PROTECTING AGAINST PINCHES OR CUTS
Aprons, gloves and armbands which can protect from pinches or cuts are utilised in workplaces where working with meat. Norm UNI EN 412 "Protective aprons for knife use" contains, among other things, requirements related to the material, penetration resistance, configuration and markings of personal protection equipment. Protective clothing is generally formed of a metal fabric in stainless steel or nickel-plated brass.
PROTECTIVE CLOTHING FOR USERS OF PORTABLE CHAIN SAWS, ACCORDING TO UNI EN 381
Users of chain saws must be protected from cutting hazards, especially near the legs and abdomen.
Norms UNI EN 381 establish requirements for leg protection. Protection against cutting is generally formed by layers of material or an assembly of single, very long filaments. If the chain of the saw cuts the upper layer of the material, the filaments of the protective insert are ripped out, blocking the chain wheel and immediately blocking the chain saw.
WARNING CLOTHING ACCORDING TO UNI EN 471 AGAINST ROAD TRAFFIC HAZARDS
3 classes of warning clothing have been established regarding the minimum fluorescent background surface material and reflecting material.
- Class 3: ex. work suit, jacket
- Class 2: ex. vest, coat, trousers
- Class 1: ex. suspenders in reflecting material
Orange-red, yellow and red fluorescent colour backgrounds are allowed.
CLOTHING FOR PROTECTION AGAINST RADIOACTIVE SUBSTANCES
Clothing for protection against radioactive substance contamination and not from radioactive radiation. Protective clothing is covered and impermeable to air and is utilised together with respiratory protection devices in works where fissionable or radioactive substances are used. An EN norm for protective clothing against radioactive contamination is currently being created.
