Depending on the accessibility afforded by adjacent equipment, aged ladders and access platforms are often quoted as options by vendors. Square body configuration systems (plan view) have square body and plenum sections. Safety handrails surrounding the plenum are standard. Structural supports are usually optional, the height of which depends on system location. Figures 3 and 4 provide sketches of the two basic configurations. 

Figure 10-5 shows a very large integral compressor. Tbi.s would he typical of compressors in the 2.000 hp to 13,000 hp size. The size of this unit can be estimated by the height of the handrails above the compressor cylinder on the walkway that provides access to the power cylinders. This particular unit has sixteen power cylinders (eight on each side) and four compressor cylinders. 

However, in the plant where the accident occurred, they were not satisfied with this easy way out. They looked into the accident more thoroughly. The injured man was asked why he had not used the handrails. 

It then came to light that the handrails were covered with plastic and that anyone using them and wearing insulating footwear acquired an electric charge. When he touched the metal of the plant, he got a mild electric shock. The spark, of course, was not serious enough to cause any injury. But it was unpleasant. People therefore tended not to use the handrails.

In 1953, James Watson and Francis Crick made their classic proposal for the secondary structure of DNA. According to the Watson-Crick model, DNA under physiological conditions consists of two polynucleotide strands, running in opposite directions and coiled around each other in a double helix like the handrails on a spiral staircase. The two strands are complementary rather than identical and are held together by hydrogen bonds between specific pairs of... 

Myriad FRP products are available for either the repair or the outright replacement of existing structures. In addition to chemical-process pipes and tanks, FRP composite products include structural shapes, bridge systems, grating, handrail ladders, etc. 

Efforts to decrease the risk of falling include balance training, muscle strengthening, removal of hazards in the home, installation of fall-reduction measures such as handrails in the home, and discontinuation of predisposing medications.1,2,10 Additionally, the use of hip protectors is an effective way to prevent hip fractures, although adherence to this measure is poor, and some patients may not be amenable to wearing them at all.10... 

Facing the depiction of the High Priestess, enter the left-hand spiral stairway. Feel the warm breeze blowing from behind and below hold onto the red handrail if need be, and walk up the clockwise spiral of stairs until you come to stand before the crystal door to the Turret Room.

Two days before the incident, the maintenance foreman, the shift foreman, operations engineer, and two pipefitters discussed the job. The scope of the job included repairs to handrails and walkways. Concerned supervision decided that burning and welding would be permitted on the structural steel that was located on top the tank. However, the supervisor declared no burning and welding on the actual surface of the tank top would be allowed. 

The purchased cost for plate and packed towers can be divided into the following components (1) cost for shell, including heads, skirts, manholes, and nozzles (2) cost for internals, including trays and accessories, packing, supports, and distributor plates and (3) cost for auxiliaries, such as platforms, ladders, handrails, and insulation. 

Table 9 presents data that can be used for estimating the cost of such auxiliaries as ladders, platforms, and handrails. The installed cost of several industrial-type insulations, all with aluminum jackets, for towers and tanks may...

I opened the door, left it open, started to climb. It was narrow, with no handrail the treads creaked. I turned a comer at the back of the shop and mounted more steps until I was facing another door. I rapped on it with the hilt of my dagger. Noting that it opened outward and the top tread was barely larger than any of the others, I hammered again, then backed down two steps. There was a chink of daylight under the door, and in a moment it was darkened by a shadow.
