Debris nets

With all scaffolds, brick guards and debris netting should be used to prevent materials and equipment falling to the ground. 

When the work is to take place in a busy area, all the normal safety features of scaffolding apply, but, in addition, special care should be taken with ladder access, debris netting and fans. Appropriate traffic signs (and possibly traffic lights), cones, barriers and lighting arrangements at night will also be necessary. 

Use toeboards, screens, guardrails and debris nets. Barricade the area and post signs and...

Where work at height is involved, debris netting, fans or other suitable measures to protect the public must be installed where assessment of the risk requires. Flammable and hazardous materials must be identified in advance and correctly controlled and stored.

Evaporation is influenced not only by the amount of energy available but also by the amount of water available. If unlimited volumes of water are available in the soil and on surface areas, this is referred to as potential evapotranspiration, i.e. the highest possible evapotranspiration under given climatic conditions. The actual evapotranspiration is the evapotranspiration which can effectively be observed. This is always lower than potential evapotranspiration and is dependent on water availability, plant and surface attributes, net radiation, air humidity, and wind speed. In mountains with a great deal of barren soil and large areas of debris and rock cover which are unable to store water in any great quantities, and with fastflowing water over steep terrain, actual evapotranspiration is very often limited and hence much lower than potential evapotranspiration. 

During a 4-month site remediation at the Summit Scrap Yard in Akron, Ohio, a manual version of the full-scale IT Corporation DWS had a net cost ranging from 50 to 75 per ton for on-site debris decontamination (D107277, p. 111). 

The scavenging effects of clays, organic debris and hydrous oxides outweigh the dissolution of Ra by chloride in the surficial environment. As a result there is a net deficit of Ra in stream waters entering the oceans, even though the water in the oceans contains an excess of Ra (Cochran, 1979).
