There are a variety of occupational harmful factors in chemical production, such as toxic chemicals, productive dust, corrosive chemicals, harmful physical factors (high temperature, low temperature, etc.) or biological factors. Under certain conditions, occupational harmful factors directly affect the human body, impair health, and cause occupational diseases. Today's safe work requires toxic and hazardous workplaces that require the necessary emergency eyewash and rinse equipment. Article 23 of the "Prevention and Prevention of Occupational Diseases Law" stipulates: "For toxic and hazardous workplaces where acute occupational injuries may occur, the employer shall set up alarm devices, configure on-site first-aid supplies, washing equipment, emergency evacuation channels, and necessary evacuation zones. "China's relevant design specifications have also made provisions," 4.4.1 and 4.6.5 of "Safety and Sanitation Design Regulations for Chemical Enterprises" (HG20571-95), and "Occupational Safety and Sanitary Design Specifications for Petrochemical Enterprises." 》(SH 3047-93) Sections 1.10.5, 2.8.2, and 5.7.10, “Safety and Sanitation Design Provisions for Chemical Powder Engineering†(HG20532-93) Section 5.5.1 Both Clause 9 and Article 7.2.4 have made explicit provisions requiring the installation of necessary eyewash, shower and other safety and health protection facilities.
Eyewashers and showers are used as first-aid devices in the event of an accident. The purpose of the eyewash and shower devices is to provide the eyes, face or body where the water is flushed with chemical splashes at the first time to reduce the damage that chemical substances may cause. Whether the flushing is timely or thorough is directly related to the severity and prognosis of the injury. However, they only perform preliminary treatment of the eyes, face and body. They cannot replace basic protective equipment such as protective goggles, splash-proof masks, protective gloves, splash robes, and chemical protective clothing, nor can they replace the necessary safe disposal procedures. Replace medical treatment.
With regard to the detailed setting of eyewashers and showers, our country has only specified in Article 4.1.4 of the "Safety and Sanitation Design Regulations for Chemical Enterprises" (HG20571-95) that its service radius is less than 15m. The American Standard ANSI Z358.1—2004 has been recognized as an international standards for eyewash and shower washers in many countries. It is also used as a standard for many countries such as the Australian Standard AS4775-2007 and CNSl4251 T2048-1998 in Taiwan Province of China. in accordance with. The European standard EN15154—1&2:2006 provides detailed provisions for the installation, use, specification, testing, etc. of vertical body irrigators and vertical intraocular irrigators used in laboratories. The European standard EN 15154—3&4: Vertical body flusher and non-vertical intraocular flusher.

A typical version of an overhead garage door used in the past would have been built as a one-piece panel.The panel was mounted on each side with unequal parallelogram style hinge lifting mechanism. Newer versions of overhead garage doors are now generally built from several panels hinged together that roll along a system of tracks guided by rollers. The door is balanced by either a torsion spring system or a pair of extension springs.A remote controlled motorized mechanism for opening garage doors adds convenience, safety, and security
• Aluminum garage doors are low-cost, light, rust-proof, and feature low-maintenance. They are prone to denting because aluminum is not strong and they are energy-inefficient since aluminum is a highly conductivematerial.
• Fiberglass and vinyl garage doors are composite units, combining a steel core behind a fiberglass or vinyl skin. They have also polyurethane insulated base sections, or other type of foam insulation. These premium doors can match steel garage doors, and be a realistic imitation of wood (namely fiberglass units), but they may be more expensive than steel units.
• Steel doors have become common and are available in a variety of sizes and styles, provide strength and security, are cost-competitive, and may have optional insulating value. Extra strength is available with two or three layers of galvanized steel with a low gauge number (23-24 gauge steel panels).
• Wood garage doors offer aesthetic appeal, but they are high-maintenance and may be expensive. Low-priced wood garage doors may warp and break easily.
