Table 4 shows injuries related to table saw blade contact during the 2007-2008 period. The article also discusses the influence of user movement and safety features on injury risk. If you use a table saw, the following safety tips may help you avoid injuries. Read on to learn more. After you have finished reading this article, you’ll be able to prevent injuries on your own. But if you’re still not sure, read on for more information.
Table 4: Table saw blade-contact injuries in 2007-2008
In 2007, the number of table saw-related non-occupational injuries rose to 12,059, with 4% of the total being minors. Adults sustained hand injuries eighty-seven percent of the time, compared to thirty percent for all other consumer product injuries. Children are also more likely to sustain head, neck, and facial injuries. Overall, the patterns of injuries are similar between males and females, although the male proportion is slightly higher than the average.
During the special study, CPSC staff identified several trends in participant responses. One pattern was a possible effect of the type of interviewer. Two different interviewers from the same company interviewed participants in 94 percent of cases. Significant differences were found in responses to critical questions, such as the type of table saw involved, the use of safety features, and the activities that preceded the injury.
Although the use of a blade guard is strongly recommended, CPSC staff noted that in many cases the injury victim did not use a blade guard. The prevalence of unintentional injury by a table saw is low compared to other power tools. More than 40,000 people are injured each year by power tools, and yet the power tool industry is resisting safety measures. The power tool industry cannot afford to ignore the safety of their saws, as safety technology has been available and is affordable.
The majority of the victims of table saw injuries were males. Forty percent were hospitalized. In addition, the victims were older than six years, making them the oldest group of victims. The rate of hospitalization for such injuries is high among males. Moreover, a large percentage of the victims was older than sixty-one. In addition, injuries were diagnosed in emergency rooms despite the voluntary standard.
The proposed rule would implement an active injury mitigation system that detects contact between a rotating blade and a human body part. The blade would be stopped within a few thousandths of a second if the blade comes in contact with a human body part. This rule would have an indirect effect on the number of injuries caused by table saws, but if it is adopted by manufacturers, it would be a boon for workers.
The CPSC currently has five commissioners. They voted in June 2011 to make table saw safety a priority. Chairman Inez Tenenbaum then directed staff to produce a briefing package. This staff report recommended that the Commission proceed with an advanced notice of proposed rulemaking, or ANPR. On October 5, 2011, the ANPR was unanimously approved. If the new standard is adopted, table saw injuries will decrease significantly.
As the human body is conductive, injuries from table saw blade-contact are highly likely to occur. CPSC staff members reviewed incidents involving unexpected workpiece movement, categorized by type of blade-contact scenario. Most blade-contact injuries were associated with unexpected workpiece movement. This suggests that table saw blade-contact incidents are due to unexpected movement, not sudden and deliberate use. If the workpiece is not supported by the miter gauge, the workpiece may jam in the blade guard.
Impact of user’s movement on injury risk
After a massive public outcry, the CPSC is now looking at the impact of a new table saw safety standard on the number of injuries associated with table saws. The new standard is meant to help consumers avoid injuries. The CPSC says it will publish an Advanced Notice of Proposed Rulemaking in the fall of 2010.
However, the manufacturers of table saws have been reluctant to implement this safety advance because they are worried about the liability associated with conventional saws. In recent years, the table saw industry has faced at least 150 lawsuits, and has refused to implement any safety technologies to lower the risk of injuries. However, Whirlwind Tool Co. has developed a system that uses a proximity detection sensor to reduce injury risk.
The latest studies have shown that most table saw injuries result from contact with the blades without a guard. Despite the safety features of blade guards, many tasks can’t be completed with one, and many consumers choose to remove the blade guard anyway. Despite these precautions, the table saw injury risk continues to rise, with the number of amputations now exceeding four thousand a year.
The rule will have the biggest impact on costs, but it will reduce injuries by as much as $625 million. In the short term, the cost of the rule will be offset by efficiencies in manufacturing processes and economies of scale. The implementation date of the rule is yet to be determined, but the rule should be in place by the end of 2018.
The Fifth Circuit clarified some of the issues raised in Southland Mower and Aqua Slide by determining that spinning blades pose a significant risk to consumers. The Fifth Circuit concluded that the new standard will be needed to protect consumers from injury. However, the industry must still take the time to implement the safety technology because it could reduce liability lawsuits. That means that a table saw safety device should be installed on every table.
A study of table saw safety showed that in the United States, a 10-inch blade spins at four thousand rpm and its outside edge is 108 mph, which means a cut is made every 370 microseconds! This is a much higher rate than the other common workplace injury, but it’s also more effective in preventing amputations and other serious injuries. If properly installed, this technology could help prevent most injuries associated with table saws.
According to the National Institute of Health and Safety, over 67,000 workers are injured with table saws each year. These accidents result in nearly three thousand emergency room visits, 4,000 amputations, and $2.3 billion in societal costs. The only saws equipped with skin-sensing safety technology are those made by SawStop. The rest of the industry has ignored this technology. Until now, however, these saws are generally considered to be a fairly safe tool when used within their limitations.
Impact of manufacturer’s safety features on injury risk
CPSC staff studied the effects of table saw blade-contact injuries to identify factors that could have decreased the likelihood of injuries. These factors included the user’s training, environment, and experience. In addition, CPSC examined the effectiveness of safety features such as blade guards and safety cut-off switches, which are custom-designed for continuous use. In addition, CPSC staff compared the table saw injuries to other consumer products, identifying trends in demographic groups and hazards.
Active injury mitigation systems (AIM) mitigate the risk of injuries caused by the rotating saw blade by removing or retracting the blade after contact is made with a human body. This feature has several benefits, including reducing the severity of an injury, since it reacts to contact with the user’s body. Passive systems, on the other hand, provide a barrier between the blade and the user.
While CPSC reports that table saws with modular blade guards reduce the risk of blade-contact injuries, the CPSRMS survey finds no evidence that this feature reduces the incidence of injuries. Further, a modular blade guard is not sufficient to minimize the risk of blade-contact injuries. The CPSC staff also identified several incidents of injury caused by riving knives or a protective blade.
While some consumers may prefer a table saw with AIM technology, others might opt for a model without AIM. Ultimately, a proposed rule may prevent consumers from buying a table saw without an AIM, which would greatly reduce the risk of serious blade-contact injuries caused by these tools. So, the question remains: How can consumers determine which table saw is safest? In this article, we’ve taken a closer look at the proposed rule and what we can do about it.
Trend analyses of the number of table saw injuries by type of exposure, hospitalization, and amputations conducted by CPSC staff showed that there has been no significant change in the incidence of these injuries. A trend analysis of blade-contact injuries per thousand table saws in use concluded that the risk of amputation and finger/hand injuries is not significantly reduced despite the introduction of the safety features.
In addition to product-related reports to CPSC, table saw-related injuries are not typically reported. In fact, CPSC received relatively few reports from news articles, consumers, attorneys, manufacturers, and retailers. However, the NEISS data does not represent a complete sample of injuries caused by table saw blade-contact. The trend analysis only used data from 2004 to 2015, so CPSC staff cannot say with certainty how many of these injuries are caused by table saws.
