Wind socks

Wlien there are unwanted incidental releases of highly hazardous chemicals in the process area, the employer must inform employees of the actions/procedures to take. If the employer wants employees to evacuate the area, then the emergency action plan will be activated. Eor outdoor processes, where wind direction is important for selecting the safe route to a refuge area, the employers should place a wind direction indicator, such as a wind sock or pennant, at the highest point visible...

Wind vane is the instrument used to determine the direction in which wind is blowing. Wind vane points into the wind or the direction from which the wind is blowing. For example, if the wind vane points towards the north east, it indicates a north east wind. It has a light arrow where the arrow tail points in the opposite direction. In airports, wind socks are used. 

Figure 2.42 shows a photo of a wind sock located near fuel gas piping. This sock can be used to determine what direction leaking chemicals might be taken by the wind in the event of a leak. This is particularly important for toxics that could harm personnel and flammable materials that could start or feed a fire. In general, personnel would normally want to go upwind of leaking equipment unless that path would be more hazardous (e.g., they would have to go through a fire to get upwind). 

Wind socks are used to determine the direction of the wind. The sock points in the same direction the wind is blowing. Wind socks... 

Stake the upright twig in the ground, perhaps in a garden, about a few inches deep. The ends of the husks should not touch the ground. When the wind blows, the little cornhusks of your Natural Wind Sock will twirl, wiggle, and float in the same direction.

Contrast-enema usually reveals a microcolon distal to the atresia, with obstruction to the retrograde flow of barium at the site of the atresia (Fig. 1.29). A wind-sock appearance may be observed with membranous atresias (Winters et al. 1992). Calcification of meconium peritonitis due to in utero bowel perforation is present in about 12% of atresia cases, and can be diagnosed antenatally by sonography. 

If the leak is extensive, all persons in the path of fumes should be evacuated by the proper authorities. If outdoors, keep all persons upwind from the leak. Also, if possible, keep all persons in locations higher than the leak. At sites involving the handling of chlorine outdoors, it is advisable to have a wind sock or weather vane installed in a prominent location to readily determine wind direction. Unless there is a fire-caused updraft, gaseous chlorine tends to lie close to the ground or floor because it is approximately 2 times as heavy as air.

Direct evaluation of the convective heat transfer coefficient (h ) of subjects clothed in undergarments and socks (normal ventilated environment) was achieved by observing the sublimation rate of naphthalene balls uniformly positioned three centimeters from the body surface. Equations were developed for prediction of h as a function of metabolic activity and posture, calculation o average skin temperature, and estimation of maximum evaporative heat losses from the body (U2 ). In another approach, the coefficients of dry heat transfer at varying wind speeds for nude and clothed sectional mannequins were determined (U3). At air flow rates above 2 m/sec, percentage contributions of individual body sections to total heat transfer remain constant for the nude and clothed mannequin, yet increased for normally uncovered units such as the face and hands. Generally, the ratio of total heat flow for the nude to clothed mannequin increased with air flow. 

Hr Don t wait until the last minute If you re furiously throwing things into bags at midnight before your 5 00 a.m. flight, you may wind up in Paris with a camp lantern. Instead, start packing a week in advance. Leave your suitcase open in a corner of the room, and stash items you have multiples of, like socks, underwear, and dental floss. (Keep your packing list and a pen nearby.)...
