Protective clothing - Protection against liquid chemicals - Performance requirements for chemical protective clothing with liquid-tight connections between different parts of the clothing for emergency teams (Type 3 ET Equipment)
This European Standard specifies the minimum requirements@ test methods@ marking and information supplied by the manufacturer for the following ventilated and non-ventilated liquid-tight chemical protective suits. Full body protective clothing with liquid-tight connections between different parts of the clothing (Type 3 liquidtight clothing) and@ with liquid-tight connections to component parts@ gloves@ boots@ visors or respiratory protective equipment@ which may be specified in other European Standards. Examples of such clothing are onepiece coveralls or two piece suits@ with or without hood or visor@ with or without boot-socks or over-boots@ with gloves attached liquid tight to the suit. It describes personal protective ensembles for use by emergency teams@ e.g. first responders or fire brigades@ in situations where the chemical hazards are known. Type 3- ET suits are generally used during rescue operations@ salvage work@ cleanup and decontamination procedures@ especially to protect against liquid and solid chemicals. Chemical protective clothing conforming to this standard is not designed to provide protection against gases and vapours@ nor substances with a high vapour pressure. Suits described in this standard have to completely cover the body. It is designed with liquid tight connections to suit socks@ or booties and liquid tight gloves. They are not designed as respiratory protection@ but they need to provide adequate liquid protection (Jet test) where joints to respiratory devices are required. Minimum performance classes for mechanical properties are defined. This standard specifies special performance requirements for both the materials of construction of the chemical protective suit and for the suit as a whole@ including component parts@ such as respiratory protective devices@ gloves@ boots@ seams@ joins and assemblages. This standard does not establish minimum criteria for protection for non-chemical hazards@ e.g. radiological@ fire@ heat@ explosives etc. This type of equipment is not intended for total immersion in liquids. Chemical protective clothing conforming to this standard is not designed to provide protection against gases and vapours. The basic performance criteria for the component parts: gloves@ boots or respiratory protective equipment are given in other European Standards@ (these Type 3-ET garments need to fulfil the requirements of the related product standards for gloves or boots etc@ and the minimum requirements defined in this Standard). The chemical protection suits specified in this standard are designed to be used with respiratory protective devices.
