Ladder safety you and I need to know
Ladder can be seen everywhere in the workplace. It provides personnel to climb to facilitate various operations, maintenance, and access to items. It is almost indispensable in many workplaces. Because the ladder is simple in structure and convenient to use, most people always think that the ladder has nothing. According to the data of the US Bureau of Labor Statistics, a total of 25,383 people were injured when they fell from a ladder during work in 1996 (therefore, 95 of them were unable to work on leave). Danger, because of this, its potential danger is often easily overlooked. People died, and 30% of the injured took leave for more than 30 days. It is directly visible that the seriousness of ladder hazards, so how to safely and correctly replace, inspect and use ladders is worthy of our attention.
How to choose a ladder or scaffold (commonly known as scaffold) when working at high places? The simple principle is that for long hours of work or tasks that require horizontal movement, it is best to use scaffolding. If you need to use a ladder, you must choose a suitable ladder. Ladder is basically divided into two categories, one is a straight ladder, and the other is a stepladder. A straight ladder cannot stand alone and must lean against a fixed object. The U.S. Occupational Safety and Health Administration (OSHA) stipulates that the length of the top of the straight ladder must be 91 cm (3 feet) higher than the horizontal surface to be reached. The safety and health facility regulations stipulate that it is 60 cm or more), which is usually called overreach. The purpose of overreach is to make the center of gravity of the straight ladder close to the fixed object, and the ladder is less likely to overturn when people get on and off. However, if the straight ladder cannot meet the overextension requirements, the top of the ladder must be fixed, and the ladder should be equipped with grabbing devices or handrails to provide personnel and the ladder to maintain three-point contact at any time (ie two feet and one hand). For the use of combined ladders, my country's labor safety and health facilities regulations stipulate that the feet of the ladder and the ground should be within 75 degrees, and there is a tie between the two ladder feet.
There are ladders made of metal, wood, fiberglass, and other materials on the market. What kind of ladder should be used? Although many people know that metal ladders cannot be used in places where electric shocks may occur, there are still many people in the United States who die of electric shocks due to metal ladders falling on bare wires every year, but pay special attention to them, even wooden ladders and The glass fiber ladder may also have the problem of electric induction when it is wet. Although the glass fiber ladder has the advantages of strength and lightweight, the glass fiber material is easily degraded by sunlight, and other chemicals are also easy to damage the glass fiber. Therefore, when using glass fiber ladders, special check for damaged features such as discoloration or cracks. Wooden ladders have the disadvantages that they are heavier than aluminum ladders and are easily damaged by aging.
When choosing a ladder, pay attention to its maximum load limit, and pay special attention to those who are overweight or carry overweight items on and off the ladder. The United States is divided into four levels according to the load of the ladder: light-duty, medium-duty, heavy-duty and extra heavy duty. The maximum load is 91 kg (200 lb) and 102 Kg (225 lb), 114 kg (250 lb) and 136 kg (300 lb),150KG(375lb).
