Which eyewash should my business install?
Emergency showers are designed to flush the user’s head and body, do not use emergency showers to rinse eyes, high-pressure water or high-speed water flow will cause secondary damage to the eyes. Eyes exposed to harmful substances using eyewashes. Runwangda eyewash manufacturers provide emergency eyewash shower rooms, with shower and eyewash functions.
Installing an emergency shower or emergency eyewash depends on the nature of the chemicals used by the worker and their workplace tasks. The potential hazards of the job and the work area must be assessed prior to the job. Choose an emergency shower or emergency eyewash, or an emergency shower combination eyewash due to safety precautions.
Then some working environments and implementation of work may cause damage to the eyes, so installing an emergency eyewash is a suitable choice.
In some working environments and implementation operations that have chemical sources and may be sputtered or sprayed on the work staff, emergency shower composite eyewashes are appropriate.
The Emergency Shower Compound Eyewash can be used to shower part of the body or the whole body. It can be said to be a full range of personal protective products. Products in this category can be installed in places where the source of danger is not clearly indicated, or where there are various sources of hazard.
What are the requirements for my business to install eyewash equipment?
Note: All dimensions and measurements are taken from American National Standards Institute (ANSI) standard Z358.1-2014 [Emergency showers and emergency eyewashes]. However, not all dimensions and measurements required by the ANSI standard are listed here.
Emergency showers should be available in shower size of at least 50.8 cm (20 in) and 152.4 cm (60 in.) in diameter. This diameter ensures that the water will touch the entire body – not just the top of a person’s head. ANSI also recommends that shower heads be 82-96 inches (208.3 to 243.8 cm) from the floor. The minimum capacity of the shower should be 75.7 liters per minute (20 gpm) and the minimum time should be 15 minutes.
Emergency showers should also be designed to be activated in less than 1 second and do not require the use of a person to continuously hold the valve (emergency shower lever). The height of this valve should not exceed 173.3 cm (69 inches). If using a housing, make sure there is an accessible area measuring 34 inches (86.4 cm) in diameter.
Emergency eyewashes/stations, portable eyewashes should be designed to simultaneously deliver water or liquids to both eyes in a volume of at least 1.5 liters per minute (0.4 gpm) for 15 minutes (without interruption). The combination of eyewash and face wash requires 11.4 liters per minute (3.0 gallons per minute). However, in the previous two cases, the speed of the eyewash should be slow to approach the requirements and not rinse too fast to cause secondary injury. The device should be 83.8 to 134.6 cm (33 to 53 inches) from the ground and at least 15.3 cm (6 inches) from a wall or the nearest obstacle.
Why is it necessary to have an emergency shower combination eyewash in an area with a hazard source?
The first 10-15 seconds of exposure to hazardous substances, especially corrosive substances, are very important. Use the emergency shower complex eyewash to reduce damage to the skin and other areas by harmful substances. Even these few seconds can lead to serious injury to body parts.
Emergency shower compound eyewash can reduce the damage of harmful substances to the body and other parts, in order to avoid secondary injury, emergency shower combination eyewash must be installed in a conspicuous and barrier-free position. In many cases, employees were injured when they did not wear protective glasses in accordance with safety regulations.
Emergency showers also play a role in extinguishing burning clothes and flushing out harmful substances from clothes.
Where should emergency showers and emergency eyewashes be installed?
Emergency shower eyewashes do not have the best place to install, only the most suitable place. Installation makes the user more effective use is the most suitable! The ANSI recommends that a person be able to reach the device in no more than 10 seconds. From a practical point of view, it is necessary to consider that the user of the equipment will be injured when working within that range, and it is very important that the user’s vision may decline after the injury, and it is impossible to correctly determine the location of the emergency shower eyewash. ANSI regulations state that the average person can walk about 16 to 17 meters (55 feet) in 10 seconds, but the above statement cannot be classified as the physical and emotional condition of the user in an emergency.
Then, depending on the potential impact of the chemical on the user, the “10 seconds” mentioned in the ANSI rules can be improved to allow the user to reach the emergency shower eyewash in a faster time. If highly corrosive chemicals are used in the work area, emergency showers and emergency eyewashes may need to be installed close to the work area. Consult a professional with knowledge in the field. When the chemical corrosion of the working area is particularly severe, adapt to the installation of emergency showers or emergency eyewashes with anti-corrosion materials.
The location of each emergency shower or eyewash is marked with a highly visible sign. Signs should come in the form of symbols that do not require workers to have the skills to understand language. The location of the installation should be well lit.
How long does it take to flush or rinse your eyes with an emergency shower multi-eyewash?
ANSI Z358.1-2014 stipulates that the emergency shower compound eyewash installed must be continuously rinsed for at least 15 minutes. Continuous is uninterrupted rinsing.
For non-irritating or mildly irritating hazardous substances, continuous rinsing for at least 5 minutes is required.
For moderately irritating or severely irritating chemicals, continuous rinsing for at least 15 to 20 minutes is necessary.
If absorbed through the skin can cause acute poisoning, most caustics require continuous rinsing for 30 minutes.
For strong bases (e.g. sodium hydroxide, potassium hydroxide, strong calcium oxide) a continuous rinse of more than 60 minutes is necessary.
If you still feel tingling beyond the continuous rinsing, be sure to consult your doctor for ASAP!
Can you provide a few suggestions for installing an emergency shower eyewash?
Install emergency shower eyewashes close to hazard sources/work areas.
Do not do partition treatment
The place of installation must be visible and unobstructed on the road, it is recommended: do not pass through doorways, over machinery, or other obstacles to use the place.
Install on the same floor as the hazard source or work area, it is recommended that there are no stairs between the work area and the emergency equipment.
Whenever possible, install an emergency shower eyewash at the emergency exit so that any response or convenience can be quickly reached by emergency personnel
Install in…… Please contact the eyewash manufacturer to learn more!
Are there any basic specifications for emergency shower combined eyewashes?
Ancillary Information: All based on emergency shower complex eyewash equipment in American National Standards Institute (ANSI) standard Z358.1-2014. However, most of the dimensions and specifications are included in the following answers.
The spray range of the emergency shower is 152.4 cm, with a diameter of 50.8 inside. This diameter is the part that ensures contact with the entire body rather than the top of the head of the person. ANSI also recommends a distance of 208.3 to 243.8 cm between the inside of the shower tray and the floor. The minimum emergency shower has a capacity of 75.7 liters per minute (i.e. 20 gallons per minute), and the emergency shower must be a minimum of 15 minutes of continuous rinsing.
Emergency showers must be designed to be switched on within one meter and do not require the user’s hand to continuously hold the tie rod valve; You can continue to rinse for 15 minutes. The height of the tie rod valve must not exceed 173.3 cm, and there must be no obstruction within 86.4 cm.
Emergency eyewashes should be designed to meet or exceed 1.5 liters/min (0.4 gpm) flow rates with a continuous 15-minute rinse in both directions. The flow must be tempered in height and not cause a second injury. Emergency eyewashes should be between 83.8 cm and 134.6 cm above the ground and must be at least 15.3 miles away from the wall or the nearest obstacle.
Are there eyewashes for people with disabilities?
Yes, we have designed ADA eyewashes for people with disabilities in laboratories and storage-type eyewash stations for chemical plants according to the size of wheelchairs. Contact Runwangda eyewash manufacturers to give you more eyewash product sizes
What kind of water is in the eyewash connected by the water pipe or what kind of water source is needed to meet the standard specifications?
According to the 2009 and 2014 editions of ANSI, the February 2015 revision stated:
“For plumbed emergency eyewash stations and showers, the source of flushing fluid is typically potable tap water from a municipal or on-site water supply. Eyewash units should be constructed of noncorrosive materials.”
For piped emergency eyewash stations and showers, the source of flushing fluid is usually tap water from municipal or on-site water supplies. The eyewash should be made of non-corrosive materials.
Runwangda pointed out: Whether it is an eyewash station or a shower, it is necessary to use a drinking water source, so that secondary injuries can be completely avoided!
Does the ANSI standard specify what type of eyewash device is used in the specified hazard source?
The ANSI standard does not provide application-specific details on what types of equipment are required and there are specific hazards in the working environment. Users should conduct a work hazard analysis and consult the Safety Data Sheet to assist in this decision. Another helpful resource is the NIOSH Chemical Hazard Hazard Sources Guide. In addition, eyewash manufacturers are a valuable resource to assist in assessing the precise needs of the work area.
Are the built-in faucet eyewashes ANSI compliant?
As long as the built-in faucet eyewash is tested, it can be regarded as meeting the requirements of the eyewash standard and installed into the faucet, and at the same time ensure that the overheated warm water is used, otherwise the overheated warm water temperature will directly cause secondary damage to the eye tissue.
How does the requirement of “no more than 10 seconds” translate into distance?
Eyewash and shower stations must be located at locations that take no more than 10 seconds to reach. Most able-bodied people walk an average distance of about 55 steps in 10 seconds. Special consideration should be given to employees with disabilities, as well as hazardous substances in work areas where high priority. Emergency showers should be located at the same level as hazards and paths, and there should be no obstructions in walking.
What are the design considerations for eyewashes and emergency showers to accommodate people with disabilities?
Some important accessibility dimensions are: eyewash head height, eyewash knee clearance, and shower valve handle height. Consult the eyewash manufacturer.
Do eyewashes need to be equipped with dust covers (covers)?
A dust cover (cover) is needed on the eyewash head to prevent the accumulation of particles that can enter the eye from the eyewash. The eyewash dust cover (cover) is designed to push the dust cover (cover) away once water flows out of the outlet.
