Grab Bar
Grab bars are safety devices designed to enable a person to maintain balance, lessen fatigue while standing, hold some of their weight while maneuvering, or have something to grab onto in case of a slip or fall. A caregiver may use a grab bar to assist with transferring a patient from one place to another. A worker may use a grab bar to hold on to as he or she climbs, or in case of a fall. Construction Grab bars must bear high loads and sudden impacts, and most jurisdictions have building regulations specifying what loads they must bear. They are generally mounted to masonry walls or to the studs of stud walls (which may need to be specially strengthened). They can be mounted through drywall into a strong wooden wall stud or other structural member, but not mounted only on the drywall, as it will not bear the users' weight. Grab bars are made of metal, plastic, fiberglass, and composites. For wet areas such as bathrooms, the material must be waterproof. Stainless steel, nylon-co ...

Americans With Disabilities Act Of 1990
The Americans with Disabilities Act of 1990 or ADA () is a civil rights law that prohibits discrimination based on disability. It affords similar protections against discrimination to Americans with disabilities as the Civil Rights Act of 1964, which made discrimination based on Race (classification of human beings), race, religion, gender, sex, national origin, and other characteristics illegal, and later sexual orientation and gender identity. In addition, unlike the Civil Rights Act, the ADA also requires covered employers to provide reasonable accommodations to employees with disabilities, and imposes accessibility requirements on Public accommodations in the United States, public accommodations. In 1986, the National Council on Disability had recommended the enactment of an Americans with Disabilities Act and drafted the first version of the bill which was introduced in the United States House of Representatives, House and United States Senate, Senate in 1988.

Fall Prevention
Fall prevention includes any action taken to help reduce the number of accidental falls suffered by susceptible individuals, such as the elderly and people with neurological ( Parkinson's, Multiple sclerosis, stroke survivors, Guillain-Barre, traumatic brain injury, incomplete spinal cord injury) or orthopedic (lower limb or spinal column fractures or arthritis, post-surgery, joint replacement, lower limb amputation, soft tissue injuries) indications. Adults aged 65 years and older have a 30% chance of falling each year, making fall-related injuries the leading cause of accident-related death for this demographic. Impact of falls Falls and fall-related injuries are among the most common but serious medical problems experienced by older adults. Nearly one-third of older people fall each year, half of which fall more than once per year. Over 3 million Americans over the age of 65 visited hospital emergency departments in 2015 due to fall-related injuries, with over 1 ...

Trapdoor
A trapdoor or hatch is a sliding or hinged door that is flush with the surface of a floor, ceiling, or roof. It is traditionally small in size. It was invented to facilitate the hoisting of grain up through mills, however, its list of uses has grown over time. The trapdoor has played a pivotal function in the operation of the gallows, cargo ships, trains, booby traps, and more recently theatre and films. History Originally, trapdoors were sack traps in mills, and allowed the sacks to pass up through the mill while naturally falling back to a closed position. Many buildings with flat roofs have hatches that provide access to the roof. On ships, hatches—usually not flush, and never called trapdoors—provide access to the deck. Cargo ships, including bulk carriers, have large hatches for access to the holds. Gallows Most 19th- and early 20th-century gallows featured a trapdoor, usually with two flaps. The condemned was placed at the join. The edge of a trapdoor furthe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Welded
Welding is a fabrication process that joins materials, usually metals or thermoplastics, primarily by using high temperature to melt the parts together and allow them to cool, causing fusion. Common alternative methods include solvent welding (of thermoplastics) using chemicals to melt materials being bonded without heat, and solid-state welding processes which bond without melting, such as pressure, cold welding, and diffusion bonding. Metal welding is distinct from lower temperature bonding techniques such as brazing and soldering, which do not melt the base metal (parent metal) and instead require flowing a filler metal to solidify their bonds. In addition to melting the base metal in welding, a filler material is typically added to the joint to form a pool of molten material (the weld pool) that cools to form a joint that can be stronger than the base material. Welding also requires a form of shield to protect the filler metals or melted metals from being contami ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Screw
A screw is an externally helical threaded fastener capable of being tightened or released by a twisting force (torque) to the screw head, head. The most common uses of screws are to hold objects together and there are many forms for a variety of materials. Screws might be inserted into holes in assembled parts or a screw may form its own thread. The #Differentiation between bolt and screw, difference between a screw and a bolt is that the latter is designed to be tightened or released by torquing a Nut (hardware), nut. The screw head on one end has a slot or other feature that commonly requires a tool to transfer the twisting force. Common tools for driving screws include screwdrivers, wrenches, coins and hex keys. The head is usually larger than the body, which provides a ''bearing surface'' and keeps the screw from being driven deeper than its length; an exception being the ''set screw'' (aka grub screw). The cylindrical portion of the screw from the underside of the head t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Railroad Safety Appliance Act
The Safety Appliance Act is a United States federal law that made air brakes and automatic couplers mandatory on all trains in the United States. It was enacted on March 2, 1893, and took effect in 1900, after a seven-year grace period. The act is credited with a sharp drop in accidents on American railroads in the early 20th century. Background After the Civil War, railroads expanded rapidly throughout the United States. The increased traffic was accompanied by an increase in accidents among railroad personnel, especially brakemen. Many accidents were associated with coupling and uncoupling of railroad cars, and particularly with the use of link-and-pin couplers, which were widely used then. The operation of hand brakes was also very hazardous. The rise in accidents led to calls for safety legislation, as early as the 1870s. In the 1880s, on-the-job deaths of railroad workers were second only to those of coal miners. Through that decade, several state legislatures enacted ...

Fixed Ladder
A fixed ladder is a vertical ladder mounted permanently to a structure. These ladders are primarily used to access roofs or other structures for industrial purposes. In the United States, these ladders are covered by OSHA and ANSI standards. Components Fixed ladders consist of the following components: * Rungs: all fixed ladders have rungs, dictated by OSHA Standar1910.27(b)(1)of no more than 12" (300 mm) on center (measured as the distance from the centerline of a rung to the center line of the next rung), and at 16" (410 mm) clear width. * Side members: These are the rails on the side of the ladder that are designed that the foot cannot slip off the end. Mostly flat bar or angle profile and sometimes channel. * Stand-off brackets: Dictated by OSHA Standar1910.27(c)(4)stand-off brackets must be at least 7" (180 mm) longer than the farthest obstruction for clearance on the back side of ladder. This means that if there is a 4" (100 mm) gutter projecting from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Construction
Construction are processes involved in delivering buildings, infrastructure, industrial facilities, and associated activities through to the end of their life. It typically starts with planning, financing, and design that continues until the asset is built and ready for use. Construction also covers repairs and maintenance work, any works to expand, extend and improve the asset, and its eventual demolition, dismantling or wikt:decommission, decommissioning. The construction industry contributes significantly to many countries' gross domestic products (Gross domestic product, GDP). Global expenditure on construction activities was about $4 trillion in 2012. In 2022, expenditure on the construction industry exceeded $11 trillion a year, equivalent to about 13 percent of global Gross domestic product, GDP. This spending was forecasted to rise to around $14.8 trillion in 2030. The construction industry promotes economic development and brings many non-monetary benefits to many cou ...
