The filling of dates such as year, month, and date shall be written in Arabic numerals by the requirements of the national standard GB/T 7408-94 'Data Elements and Exchange Formats, Information Exchange, Date and Time Representation Law'. Such as 'April 26, 2004' or '2004-04-26'. Graduation project (thesis) opening reportBackground Fall protection equipment has come a long way in adapting to the ever-changing workplace, which is no secret. Workplace injuries have decreased dramatically as a result of improved safety equipment and the implementation of new standards and laws. In 2011, 3.4 events per 100 workers were reported, compared to 10.9 incidents per 100 workers in 1972. Before 1970, fall protection was unregulated and up to employees to manage. Because of this, many workers did not use safety equipment as it was restrictive and troublesome.Fall prevention is a significant topic in todays construction sector. Before the establishment of the Occupational Safety and Health Administration (OSHA) in 1970, however, businesses were not held liable for providing safe working conditions for their employees. Employers might, at the absolute least, display signage to demarcate a fall risk area or a hazardous environment, but employees were largely responsible for their safety. Fortunately, new incentives prompted employers to address possible workplace fall hazards immediately after OSHA entered the picture. Employees work safer today than they did in the past because businesses are required to offer safe working conditions, personal protection equipment, and safety training.IntroductionIn a fall protection system, controls aim to stop workers from falling in case they fall and to prevent serious injury if they do fall. The safety system is typically implemented when workers work at height but should be considered when they work near edges such as cliffs or ledges. The falling protection devices mainly save people from falling or something falling from up。

Fall protection is required whenever employees are potentially exposed to falls from heights of four feet or above. A comprehensive fall protection device avoids injuries, saves lives, and is cost-effective. Workers are exposed to fall hazards in practically every industry. In 2010, there were 635 fatal falls, resulting in billions of dollars in workers compensation payments. On-the-job injuries cost companies about $1 billion per week in payouts to injured employees and their medical providers, according to Liberty Mutual, the nations largest private provider of workers compensation insurance. Fall protection is divided into four categories: fall elimination, fall prevention, fall arrest, and administrative controls. [1] Falls account for 8% of all work-related trauma injuries that result in death, according to the US Department of Labor. [2] In the United States, OSHA is in charge of enforcing federal statutes, rules, and regulations requiring companies to provide fall protection. [3] Fall protection equipment for linemen generally includes the following: Full-body harnesses or belts with integrated harnesses: In a full-body harness, straps are placed over the thighs, waist, pelvis, chest, and shoulders in order to distribute the force of a fall.Lifelines: The lifeline connects the body harness and the anchor. Self-retracting lifelines allow for controlled ascent and descent, and they automatically lock in the event of a fall. Lanyards: Lanyards connect harnesses to lifelines, anchors, and deceleration devices using flexible ropes or straps. Connectors: The various parts of a fall protection system are connected by connectors, from lanyards and lifelines to body harnesses and anchors. An example of a common connector is a carabineer.Anchors: A lanyard, a lifeline, or a deceleration device can be attached to an anchor point. Wood Pole Climbing Fall Protection | Pole straps: These straps wrap around a pole and attach to a workers waste to hold them close to the pole while they work. They are mostly used on utility poles.Problem: A general problem in designing a falling object defensive structure system is to find out the factual demands of the cargo since in utmost cases the cargo is neither known nor can it be measured. This problem also occurs in the operation considered in this paper where the cargo not only is unknown but may also change in a veritably fast manner by impacting on Defensive structure. In order to deal with this fact, the nonlinear control strategy has to be . stoked by a cargo estimator. This is a grueling task since its well known that the separation principle of the control of implicit energy current practices are also addressed. Employers in the shipyard industry use to protect their employees from those who would harm them. any technological advancements since OSHA adopted the rules in subpart E; and the adjustments and improvements that stakeholders have made to subpart E Marine Industry: Personnel platforms mounted to a container handling gantry cranes container spreader are extensively used in marine ports to move workers, equipment, and tools to and from container ships. Longshoremen then execute a variety of activities on board the ship, including disconnecting twist locks that hold cargo containers together, attaching and removing lashing equipment that secures the ships stacks of containers, and dealing with any other issues that may emerge. The risk of falling while transporting longshoremen to and from container ships is a serious worry for companies, ship owners, and longshoremen. Construction Industry: In the construction sector, falls are one of the most common causes of mortality. Construction-related falls are responsible for 150-200 deaths and 100,000 injuries every year, according to OSHA. Building employees are exposed to job site fall dangers on a regular basis, from steel erection to roofing to basic commercial and residential construction. A comprehensive fall prevention strategy, including the right mix of fall protection equipment, a descent and rescue plan, personnel training, and partnering with a fall protection company that understands the unique nature of your construction sites access points and potential fall hazards, is required to provide safe access for employees and contractors working at heights. Storage Industry Accidents involving standup forklift trucks have been a major concern for the material handling and storage industry over the past years. The safety of the operator associated with these trucks is seriously jeopardized in the case of tip-over or off-the-dock accidents, compartment intrusions, under the rack collisions, arms or head out of the compartment and also leg injuries due to the loss of stability. These accidents can lead to death or cause severe injuries to the operator such as broken bones and amputations. This work included alternatives to be made to the standup forklift trucks, detailed accident, and failure rate analysis of the accidents. Research status and development trend at home and abroad: When we switched from waist belts to body harnesses with shock-absorbing lanyards in the early 1990s, fall prevention technology advanced dramatically. Belts that can endure a variety of environmental extremes, connecting points that are set depending on predicted forces, limiting and self-retracting lanyards, and other advancements that address fall forces employing deceleration devices are now available. There is no longer any 'tying off to sprinkler lines' because of the industrys recognition of anchor point(s) rated to at least 5,000 pounds for personal fall arrest devices. Mobile, temporary, and permanent anchor points and lifeline systems are now available in a variety of configurations. Components that prevent rollout are becoming more common, as is a greater understanding of component metal fatigue. Rescue plans are required.Future work: I have read many articles and studied the topics which are related to Design and Fall protection devices. I have come to the conclusion that what can be developed in the future in Design and Fall protection devices. Machine Learning: Providing Feedback to Clinicians and Patients Smart Phone-Based Fall Detection and Prediction Environmental Fall Risk Factors Biomedical Fall Safety Training Apps and Games Wearables for Fall Prevention and Warnings Leading Indicators Apps Design and simulation These industries have the chance to develop more about fall protection technology. It will help fall protection technology to be more enriched.Recommendation Reference1. Nicole Randall, Author at International Safety Equipment Association. (n.d.).
