“Sanitary Standards for Industrial Enterprise Design”
6.1.7 Workplaces where toxic substances may be present or produced shall be equipped with on-site first aid supplies according to the physical and chemical characteristics and hazard characteristics of toxic substances, and set up flushing and spraying equipment, emergency evacuation channels, necessary risk relief areas and weather vanes. The risk relief area should be set low and have an anti-permeable layer, and the spilled substances and flushing water should be concentrated into the industrial wastewater treatment system.
8.3 Where there is a possibility of chemical burns and acute poisoning caused by absorption through the skin and mucous membranes, on-site emergency treatment facilities shall be set up near the work site according to the occupational harmful factors that may occur or exist and their harmful characteristics. First aid facilities should include: continuous water showering, eye washing facilities; Gas protection cabinet; Personal protective equipment; First aid kits or kits and first aid medicines; Stretchers and installations for transporting patients; Facilities for first aid treatment and emergency rescue communication equipment.
8.3.1 Emergency rescue facilities shall be clearly marked and maintained regularly in accordance with relevant regulations to ensure their normal operation. 8.3.2 Showering and eye washing facilities shall be close to the place of work where the corresponding accident may occur.
“Setting of Personal Protection Emergency System”: 1. Scope of application and setting place
1.0.3 Set up the place and location
18.104.22.168 The setting location of the safe spray eyewash is related to the distance from the point where the accident may occur, and the toxicity, corrosiveness and temperature of the chemicals used or produced, which are usually set up by the process.
(1) In the production and use area of general toxic and corrosive chemicals, including loading and unloading, storage and analysis near the sampling point, safe spray eyewash is set up at a distance of 20^-30m.
(2) In the production and use areas of highly toxic, strong corrosion and temperature higher than 70 °C chemicals and acidic and alkaline materials, including near the loading and unloading, storage and analysis sampling points, it is necessary to set up a safety spray eyewash, the position of which is set 3m-6m away from the accident (dangerous place), but not less than 3m, and should avoid the direction of chemical spraying, so as not to affect its use when the accident occurs.
22.214.171.124 In the chemical analysis laboratory, there are frequently used toxic and corrosive reagents, and there is a possibility of damage to the human body, and safety spray eyewashes should be set up.
126.96.36.199 A safety spray eyewash shall be set up near the battery charging chamber.
188.8.131.52 Safety spray eyewashes should be set up on a smooth passage, and multi-storey plants are generally arranged near or near the same axis.
Code for Occupational Safety and Health Design of Petrochemical Enterprises
4.4.2 A safety special room should be set up near the control room of the device, and the room should be equipped with safety protective clothing, neutralization pool, personal flushing facilities, eyewashes, emergency drugs, etc.
4.4.3 Near the feed pump, reflux pump and regeneration tower feed pump of the main fractionation tower, a personal neutralization pool, an accident shower and an eyewash should be set up. Within the appliance should be set up in the Device Tool and pool.
5.7.10 Phenol, acetone filling plant should be mechanically ventilated, phenol barrel filling point should be equipped with accident showers and eyewashes.
5.10.1 Equipment containing hydrogen fluoride materials shall be centrally arranged in one area, surrounded by cofferdams and obvious safety signs. The area should be equipped with a personal neutralization pool, a equipment and tools neutralization pool, a personal flushing facility and an eyewash. 5.10.5 The device shall be equipped with a special safety room, including a neutralization pool, a shower, an eyewash, and a safety protective clothing and a first-aid medicine kit.
Provisions on Safety and Sanitary Design of Chemical Powder Engineering
184.108.40.206 The workplace of highly toxic materials shall be set up nearby with emergency facilities such as water shower facilities and eyewashes. General principle of eyewash settings: The eyewash is installed in a hazardous chemical area, and the user reaches the eyewash in a straight line for no more than 10 seconds. Eyewash rescue range: within 15 meters. Eyewashes cannot be installed over the layer. There are no electrical switches around the eyewash to prevent accidents. The eyewash outlet must be connected to a sewer or wastewater treatment tank.

Regardless of domestic laws and regulations, The North American Standard (ANSI) Standard Z358.1-2014 “Emergency Eyewash and Shower Equipment” can be used as a guidance document. Before setting the problem of the region, it is necessary to clarify the types of emerge showers and eyewash.
Generally: plumbed and unplumbed. That is, whether there is a continuous supply of water.
The reason for this is that according to ANSI standards, the minimum eye shower time is usually not less than 15 minutes. Moderate chemical burns tend to last more than 30-60 minutes. Often unplumbed eyewashes, for example, 500ml or 1 L bottled eyewashes tend to last less than 15 minutes. So the unplumbed eyewash has its own limitations.
AnSI recommends that a person be able to reach the equipment in no more than 10 seconds. The standard recommends that the device should be set up to a place where a person can reach within 10 seconds. Is a very pitfallous answer. 1. No psychological or physical disorders are taken into account within the criteria. 2. The distance is not specified. However the standard has claims that normal people walk for 10 seconds at 55 ft/16 meters. This is the origin of most domestic standards of 15 meters. Back to the first question, why eyewash types are emphasized, is because if you can’t reach every hazardous chemical operation post within a 15-meter range install water supply emergency sprays and eyewashes.
You can equip an unplumbed eyewash or an emergency spray tank. The purpose of these short-term eyewash devices is to allow the injured person to initiate an eyewash emergency procedure within 10 seconds and to complete the full 15-minute flushing by moving to an emergency spray facility with a continuous water supply during the eyewash and spraying process.
