Where should the emergency equipment be located?
To be effective, the equipment has to be accessible. ANSI recommends that a person be able to reach the equipment in no more than 10 seconds. In practical terms, consider that the person who needs the equipment will be injured, and may not have use of their vision. Recommendations for this distance in linear terms range from 15 to 30 metres (50 to 100 feet ).
However, the "10 second" rule may be modified depending on the potential effect of the chemical. Where a highly corrosive chemical is used, an emergency shower and eyewash station may be required within 3-6 metres (10-20 ft) from the hazard. These units should be installed in such a way that they do not become contaminated from corrosive chemicals used nearby.
The location of each emergency shower or eyewash station should be identified with a highly visible sign. The sign should be in the form of a symbol that does not require workers to have language skills to understand it. The location should be well lit.
Other recommendations include that the emergency shower or eyewash station should:
* be located as close to the hazard as possible
* not be separated by a partition from the hazardous work area.
* be on an unobstructed path between the workstation and the hazard. (Workers should not have to pass through doorways or weave through machinery or other obstacles to reach them.)
* be located where workers can easily see them - preferably in a normal traffic pattern.
* be on the same floor as the hazard (no stairs to travel between the workstation and the emergency equipment)
* be located near an emergency exit where possible so that any responding emergency response personnel can reach the victim easily.
* be located in an area where further contamination will not occur
* provide a drainage system for the excess water (remember that the water may be considered a hazardous waste and special regulations may apply).
* not come into contact with any electrical equipment that may become a hazard when wet, and
* be protected from freezing when installing emergency equipment outdoors
What temperature should the water be?
The 2004 ANSI standard recommends that the water should be "tepid" but does not give a specific temperature. Other sources will use the term "lukewarm water". ANSI does provide a guideline that the water temperature should be under 38°C (100°F) and above 15.5°C (60°F). Temperatures higher than 38°C (100°F) are harmful to the eyes and can enhance chemical interaction with the skin and eyes. Long flushing times with cold water (less than 15.5°C (60°F) can cause hypothermia and may result in not rinsing or showering for the full recommended time (ANSI 2004). With thermal burns (injuries to the skin), the American Heart Association noted that optimal healing and lowest mortality rates are with water temperatures of 20-25°C (68-77°F).
Remember that any chemical splash should be rinsed for a minimum of 15 minutes but rinsing time can be up to 60 minutes. The temperature of the water should be one that can be tolerated for the required length of time. Water that is too cold or too hot will inhibit workers from rinsing or showering as long as they should.
Install anti-scalding devices (temperature control valve or thermostatic tempering valve), constant flow meters, and other devices that will help maintain a constant temperature and flow rate. For cold or outdoor locations, emergency showers with heated plumbing are available. In hot climates, outdoor emergency showers should also have a tempering valve so that workers are not exposed to water that is too hot.
What are examples of areas that may require this equipment?
Work areas and operations that may require these devices include:
* battery charging areas,
* spraying operations,
* high dust areas,
* dipping operations, and
* hazardous substances dispensing areas.
Q: Exactly how do freeze and scald protection valves activate?
A: Protection valves have a thermostatic plunger valve assembly. This thermostatic valve open and closes relative to the water temperature. This exchange of fresh water either warms of cools the water in the fixture and the fixture based on the type of valve used and the temperature of the water being supplied.
Q: What type of fixtures does Bradley manufacture that accommodate freezing conditions?
A: The Bradley Corporation offers three different types of products that accommodate freezing conditions.
One of the most popular solutions is the Heat Trace (S19-300), this product is built to order, and features a thermostat and electrical cable that wraps around the pipes, which are then covered with insulation. It also features a freeze protection valve that bleeds off the cold water prevents freezing if power is lost.The Heat Trace is often installed in locations that may reach -50ºF or those that require a Class I Division I or Class I Division II rating. Another alternative would be a frost-proof fixture, which features a buried ball valve, or a valve that is located inside the building, sheltered from freezing conditions. Other versions of these fixtures feature a supply connection pipe that extends into the ground below the frost line. Excess water is drained off this pipe and is expelled to prevent pipes on the surface from freezing and/or bursting when ambient temperature is below freezing. To order this fixture, a customer should know the freeze depth in their region. (S19-120HFP, S19-210HFP, S19-220HFP, S19-310HFP, S19-310TW, S19-310NN) Frost-proof valves are a third solution that are recommended for locations that may on occasion have temperatures below freezing, but primarily remain above 32° F/ 0°C. Freeze valves are activated at 45°F / 7°C and function by opening to expel water in the pipes onto the ground, or through a hose or diversion instrument attached to remove water from the pipes so it doesn't have a chance to freeze. This method is not recommended in areas where freezing temperatures are frequent and last for any extended period of time.(S45-1986, S45-1987)
Q: I need an ADA compliant Emergency Fixture, does Bradley offer fixtures that comply?
A: ADA does not directly address Emergency Fixtures in its text. Bradley does however have many fixtures that have been designed with handicapped accessibility in mind. These fixtures are referred to as Barrier-free. Bradley dedicates a specific Barrier-free section of emergency fixtures, to these handicapped accessible units.
