Static electricity Under certain conditions, such as a dry and cold climate, protective clothing may generate and release static electricity. Release is usually not dangerous unless the resulting spark can ignite flammable gas or disturb the wearer. When working around flammable chemicals, job-hunting measures should be taken to reduce potential electrostatic discharges. Under these circumstances, it is recommended to adopt the following but not limited to the following steps: watering, using a protective clothing jacket to increase the humidity in the work area, using commercial antistatic products—equipment and personnel grounding straps, and durable static dissipative treatment inside and outside protective clothing; Before the long-range class, the worker's speech was dissipated and tested. However, under explosive and flammable conditions, even if complex and detailed measures are taken to control the generation and dissipation of static electricity by static electricity, there is still the risk of uncontrolled or incidental fire or explosion that can cause serious injury. Avoid exothermic reactions Some chemicals and water react to produce large amounts of heat. If protective clothing is contaminated with a large number of such chemicals that react with water, it may be damaged due to high heat during on-site decontamination. Dry chemicals or non-reactive absorbents should be used to remove the chemicals prior to decontamination. Avoid continuous exposure This protective suit cannot be inside an unchemical chemical. Nor can it be exposed to dangerous chemical sprays or showers. If necessary, do not wear protective clothing in hazardous chemical pools. Every effort should be made to limit the direct contact of chemicals with protective clothing. If it is directly sprayed or showered with hazardous chemicals, immediately leave the area and decontaminate. Avoid suffocation Don't wear full-enclosed protective clothing without a fresh air supply, whether Grade A or Grade B. Use user-supplied full-face respiratory protective equipment, such as: 1. Open-circuit self-contained breathing apparatus (SCBA), or 2. External supply air breathing tube system, through the long tube system to provide air, with an emergency cylinder. If a closed-circuit (recirculating) respirator is used, the oxygen concentration in the enclosed protective suit may increase. The oxygen concentration is determined by the type of closed circuit respirator, the level of wearer use, the degree of durability, and the physical properties of the intended work. Air-filter respirator (APR) cannot be used in fully enclosed protective clothing, whether A or B. The APR should not be worn in a separate protective surface extending to the clavicle. Also not to be used with protective clothing that conforms to NFPA 1994 Level 3 standard with a separate protective mask extending to the clavicle. Active air filter respirator (PAPR) cannot be used with closed protective clothing. Whether it is A level or B level. If the equipment mix has sufficient air intake at the air intake or it is completely uncontaminated, the PAPR can be used in conjunction with protective clothing with a separate mask. Use of external air tubes In order to connect with an external air hose, Shanghai Changyou advises you to pay attention: Protective clothing must be equipped with appropriate NIOSH approved protective clothing interface. Note that the interface cannot be a fixed or mutual place. Pulling these devices vigorously may result in permanent damage to the protective clothing. Never use pure oxygen The use of 100% oxygen in chemical clothing poses serious fire and health threats. Use only compressed air or air tubes to provide breathing air. Totally Enclosed Protective Clothing If the oxygen level inside the externally supplied respirator increases, the concentration of chlorine depends on the type of external-type respirator, the level of activity of the wearer, and the duration of use, and the task requirements. Socks The protective sock is worn inside the outer protective boot. Socks usually do not have sufficient durability and slip resistance and therefore cannot be worn as outer protective boots. Provide hearing protection If the noise level in the suit exceeds the specified noise level, hearing protection should be provided. Use hearing protection devices recommended by professional safety personnel and do not prevent the use of protective clothing. communicate with Chemical protective clothing can hinder communication, so consider making personal communication systems. Users should also consider using gestures to communicate during training, work and emergencies when wearing respirators and chemical protective clothing.
