Introduction:
Additionally, firefighters may put on fire-extinguishing protection gear, such as fire-extinguishing protection boots and gloves. Only the factory receives the marking for export. The entire development and production of this protective supplies all-in-one machine followed GBT16556-2007 and GA 124-2013.
The radiant thermal resistance capability of the facepiece is evaluated using the Motis EN 136 Thermo Resistance Test Apparatus. The EN 136 test is divided into three classes. Thermal resistance testing shall be done in accordance with Class 3 of EN 136. The tested facepiece is fixed to a dummy head connected to a breathing machine, and it is exposed for 20 minutes at a distance of 175 mm to an 8 kW/m2 radiant panel. The leaktightness must be maintained both during and after testing, and visibility of facepiece shall remain over 4 minutes start from the test.
Standard:
EN 136-Respiratory protection device-full face mask-requirements, testing and markings GBT16556-2007 ● 5.11.3 heat -resistant radiation performance ● 6.9 Thermal radiation performance test
Respiratory organs protective supplies are to prevent harmful gases, vapor, dust, smoke, fog, and the breath of the breath or directly supply oxygen or clean air to the player to ensure the protection of the normal breathing of operators in the dust, toxic pollution or hypoxia environment User. Respiratory organs protection supplies are mainly divided into dust masks and anti -virus masks (masks) according to their functions, and can be divided into two types: filtering and isolation.
The EU stipulates that personal protective supplies must pass CE-PPE certification. Personal protection CE certification instructions are mandatory to all member states of the EU. Since July 1995, personal protection CE certification PPE instructions 89/686/EEC in February 1989 1989 It was adopted on the 21st and became the law of the European Community on July 1, 1992.
PPE is a abbreviation of Personal Protective Equipment. What PPE is referred to is a device or appliance that is worn or held or held in order to prevent one or more danger of harm to health and safety. It is mainly used to protect employees from coming to contact with chemical radiation, electric equipment, manpower equipment, mechanical equipment, or severe work injury or disease caused by some dangerous workplaces. In addition to masks, safety glass, and safety shoes, personal protective equipment includes a large number of respiratory protection equipment, protective clothing, including hard hats, goggles, hearing protectors (earplugs), safety gloves, safety shoes, respirators and seat belts.
Full face masks are covered by EN 136:1998 respiratory protection equipment.
The minimum specifications for full face mask respiratory protection equipment are laid out in this standard. Divers' full-face masks are not covered under the scope of this standard. Compliance evaluations of these standards involve laboratory and practical performance tests. A mask is a full facepiece that covers the wearer's eyes, nose, mouth, and chin and offers respiratory protection by creating the right seal against particular climatic conditions and airborne threats. Natural rubber, EPDM, and silicone are used to make respirators and masks, which can be found in a range of designs and filter configurations that comply with different safety requirements (e.g., EN 141, EN 143, and EN 371).
The three full-face mask styles covered by this standard offer the same level of respiratory protection but are used for different purposes:
• CL 1: Full mask for light duty
• CL 2: Full mask general use
• CL 3: Full mask for special use
Breathing resistance, speaking diaphragms, carbon monoxide concentration, impermeability, and temperature stability are among the requirements.
