Sustainability working platform

Figure 8.5 Typical sloping roof edge protection. Barriers shown in (a) can be useful where spaces is limited, but they are not capable of sustaining loads so large as (b) and (c) which also provide a working platform.

Tho valve, J, Fig. 41, may now be lowered by the lever, d, which, while the valve is up, has its extremityhearing the counterpoise, e, hooked to the platform by means of the small aperture seen near the counterpoise but when this is unhooked, the valve descend and the turf falls into the furnace. This being effected, tho lever is again hooked in the usual position, and the hopper recharged. In this mothod of working, the only loss sustained is merely the full... 

Polymer materials based on annually renewable agricultural and bioniass feedstocks can form the basis for a portfolio of sustainable, environmentally preferable alternatives to current materials based exclusively on petroleum feedstocks. Two basic routes are possible. Direct extraction from biomass yields a series of natural polymer materials (cellulose, starch, proteins), fibers, and vegetable oils that can form the platform on which polymer materials and products can be developed as shown in Figure 9, the bolded items in the Figure represents our work in diis area. 

An employer was cited for allowing an employee to work off an elevated platform. The employee fell 15 feet and sustained fatal head injuries. The proposed penalty was 211,900.
