What is Windsock?



windsock is conical textile tube designed to indicate wind direction and relative wind speed. Windsocks typically are used at airports and at Petro Chemical Plants Oil and Gas . Refinery Plants.  there is risk and danger from gaseous leakage. They are sometimes located alongside highways at windy locations.

Wind direction is the opposite of the direction in which the windsock is pointing (note that wind directions are conventionally specified as being the compass point from which the wind originates; so a windsock pointing due east indicates a westly. Windspeed is indicated by the windsock's angle relative to the mounting pole;  in high win it fly horizontally and when low winds, the windsock droops.

Refer  FAA standards referenced below,

1)    15-knot (28 km/h; 17 mph) wind will fully extend the properly functioning windsock.
2)     A 3-knot (5.6 km/h; 3.5 mph) breeze will cause the properly functioning windsock to orient itself according to the wind.

At many airports, windsocks are lighted at night, either by flood lights on top surrounding it or with one mounted on the pole shining inside it.

Windsocks are also popular with children and can have bright and colourful designs or make windsock flag. These windsocks are not particularly functional and mostly for decoration, however they can be used as a basic guide to wind direction and speed. You can buy winsocks from wind sock suppliers .

What 's Purpose of Eyewash Station and Showe?



Emergency Eyewash and Shower



ISEA is the trade association for manufacturers of emergency eyewash and shower equipment and systems.
Emergency eyewash and shower equipment is designed to provide emergency flushing of the eyes, face or body of a person exposed to hazardous materials.  This equipment is installed in workplaces of all types, from factories to auto repair shops, as well as laboratories, hospitals and schools.  Products include emergency drench showers, eyewash units that may be permanently attached to the plumbing system or free-standing tank systems, eye/face washes, drench hoses, drench hoses, fixed and portable decontamination showers, mixing valves and personal eyewash bottles.
ISEA members have a seat at the table when standards are being written that affect their products; they get a first look at changes in standards, they influence the development of new standards, and they are kept informed of developments on standards around the world. The ISEA standard for eyewash and showers, ANSI/ISEA Z358.1, is recognized around the world, and the group has liaison representation on the European standards committee for laboratory eyewashes. In response to homeland security needs, the group developed an ANSI standard for decontamination showers.

ISEA gives members a full-time Washington office. They are kept up to date on important developments affecting their companies, and are identified with a respected and responsible organization that is an advocate for standards and regulations for emergency eyewash and shower equipment. ISEA promotes recognition of the ANSI standard as the basis for federal and state regulation of emergency eyewash and shower equipment in the workplace, and is an active participant in US government homeland security organizations developing standards and plans for personnel and equipment decontamination. 
ISEA members use the association to learn from each other, and work together to improve markets. Information services are tuned to member companies’ needs. 
In addition to bringing companies together in the Eyewash and Shower Group, ISEA membership is a link to the larger world of safety equipment, both in the US and around the world. Companies receive regular bulletins and reports on standards, government policies and proposals, and market intelligence. They participate in the association’s Annual and Fall Meetings, where the industry comes together to share information and insight. Members’


For 75 years, ISEA has set the standard for personal safety equipment manufacturers, supporting and promoting the business interests of its member companies, united in the goal of protecting the health and safety of people worldwide.

What is Fire Extinguisher?



fire extinguisherflame extinguisher, or simply an extinguisher, is an active fire protection device used to extinguish or control small fires, often in emergency situations. It is not intended for use on an out-of-control fire, such as one which has reached the ceiling, endangers the user (i.e., no escape route, smoke, explosion hazard, etc.), or otherwise requires the expertise of a fire department. Typically, a fire extinguisher consists of a hand-held cylindrical pressure vessel containing an agent which can be discharged to extinguish a fire.
In the United States, fire extinguishers, in all buildings other than houses, are generally required to be serviced and inspected by a Fire Protection service company at least annually. Some jurisdictions require more frequent service for fire extinguishers. The servicer places a tag on the extinguisher to indicate the type of service performed (annual inspection, recharge, new fire extinguisher) and when.
There are two main types of fire extinguishers: stored pressure and cartridge-operated. In stored pressure units, the expellant is stored in the same chamber as the firefighting agent itself. Depending on the agent used, different propellants are used. With dry chemical extinguishers, nitrogen is typically used; water and foam extinguishers typically use air. Stored pressure fire extinguishers are the most common type. Cartridge-operated extinguishers contain the expellant gas in a separate cartridge that is punctured prior to discharge, exposing the propellant to the extinguishing agent. This type is not as common, used primarily in areas such as industrial facilities, where they receive higher-than-average use. They have the advantage of simple and prompt recharge, allowing an operator to discharge the extinguisher, recharge it, and return to the fire in a reasonable amount of time. Unlike stored pressure types, these extinguishers use compressed carbon dioxide instead of nitrogen, although nitrogen cartridges are used on low temperature (-60 rated) models. Cartridge operated extinguishers are available in dry chemical and dry powder types in the U.S. and in water, wetting agent, foam, dry chemical (classes ABC and B.C.), and dry powder (class D) types in the rest of the world.
Fire extinguishers are further divided into handheld and cart-mounted, also called wheeled extinguishers. Handheld extinguishers weigh from 0.5 to 14 kilograms (1 to 30 pounds), and are hence, easily portable by hand. Cart-mounted units typically weigh 23+ kilograms (50+ pounds). These wheeled models are most commonly found at construction sitesairport runwaysheliports, as well as docks and marinas.
