“Lockout/tagout” refers to specific practices and procedures to safeguard employees from the unexpected energization or startup of machinery and equipment, or the release of hazardous energy during service or maintenance activities. This requires, in part, that a designated individual turns off and disconnects the machinery or equipment from its energy sources before performing service or maintenance and that the authorized employees either lock or tag the energy-isolating devices to prevent the release of hazardous energy and take steps to verify that the energy has been isolated effectively. If the potential exists for the release of hazardous stored energy or for the reaccumulation of stored energy to a hazardous level, the employer must ensure that the employees take steps to prevent injury that may result from the release of the stored energy.
Lockout devices hold energy-isolation devices in a safe or”off” position. They provide protection by preventing machines or equipment from becoming energized because they are positive restraints that no one can remove without a key or other unlocking mechanism, or through extraordinary means, such as bolt cutters.
Tagout devices, by contrast, are prominent warning devices that an authorized employee fastens to energy-isolating devices to warn employees not to reenergize the machine while he or she services or maintains it. Tagout devices are easier to remove and, by themselves, provide employees with less protection than do lockout devices.

Ergonomics is the scientific study of people at work. The goal of ergonomics is to reduce stress and eliminate injuries and disorders associated with the overuse of muscles, bad posture, and repeated tasks. This is accomplished by designing tasks, work spaces, controls, displays, tools, lighting, and equipment to fit the employee´s physical capabilities and limitations.

And I’m proud to be an American, — Lee Greenwood
where at least I know I’m free.
And I won’t forget the men who died,
who gave that right to me.
The physical benefits of exercise — improving physical condition and fighting disease — have long been established, and physicians always encourage staying physically active.
Exercise is also considered vital for maintaining mental fitness, and it can reduce stress. Studies show that it is very effective at reducing fatigue, improving alertness and concentration, and at enhancing overall cognitive function. This can be especially helpful when stress has depleted your energy or ability to concentrate.

Liquid petroleum LP gas or propane, used in gas grills, is highly flammable. Each year about 30 people are injured as a result of gas grill fires and explosions. Many of these fires and explosions occur when consumers first use a grill that has been left idle for a period of time or just after refilling and reattaching the grills gas container. To reduce the risk of fire or explosion, consumers should routinely perform the following safety checks:
- Check the tubes that lead into the burner for any blockage from insects, spiders, or food grease. Use a pipe cleaner or wire to clear blockage and push it through to the main part of the burner.
- Check grill hoses for cracking, brittleness, holes, and leaks. Make sure there are no sharp bends in the hose or tubing.
- Move gas hoses as far away as possible from hot surfaces and dripping hot grease. If you cant move the hoses, install a heat shield to protect them.
- Replace scratched or nicked connectors, which can eventually leak gas.– Check for gas leaks, following the manufacturers instructions, if you smell gas or when you reconnect the grill to the LP gas container. If you detect a leak, immediately turn off the gas and dont attempt to light the grill until the leak is fixed.
- Keep lighted cigarettes, matches, or open flames away from a leaking grill.
- Never use a grill indoors. Use the grill at least 10 feet away from your house or any building. Do not use the grill in a garage, breezeway, carport, porch, or under a surface that can catch fire.
- Do not attempt to repair the tank valve or the appliance yourself. See an LP gas dealer or a qualified appliance repair person.
- Always follow the manufacturers instructions that accompany the grill.
Consumers should use caution when storing LP gas containers. Always keep containers upright. Never store a spare gas container under or near the grill or indoors. Never store or use flammable liquids, like gasoline, near the grill. To avoid accidents while transporting LP gas containers, consumers should transport the container in a secure, upright position. Never keep a filled container in a hot car or car trunk. Heat will cause the gas pressure to increase, which may open the relief valve and allow gas to escape.Consumers should use extreme caution and always follow manufacturers instructions when connecting or disconnecting LP gas containers. Grills manufactured after October 1, 1995, are required to have three additional safety features to eliminate leak hazards: a device to limit the flow of gas in the event of hose rupture; a mechanism to shut-off the grill; and a feature to prevent the flow of gas if the connection between the tank and the grill is not leak proof. Consumers should consider purchasing grills that have these safety features.

Sudden cardiac arrest is one of the leading causes of death in the U.S. Over 350,000 people will suffer from sudden cardiac arrest this year . It can happen to anyone, anytime, anywhere and at any age. An AED is the only effective treatment for restoring a regular heart rhythm during sudden cardiac arrest and is an easy to operate tool for someone with no medical background.
Time is of the essence:
- The average response time for first responders once 911 is called is 8-12 minutes.
- For each minute defibrillation is delayed, the chance of survival is reduced approximately 10%.

Wearing a life jacket can dramatically decrease your chances of drowning while boating. “Wear It!” every time you’re on the water.
Everyone, on all types of boats, should wear properly-fitted life jackets, or personal flotation devices (PFD). By wearing a life jacket, you can dramatically decrease your chances of drowning while boating.
Know the Facts: Recreational boating can be a wonderful way to spend time with family and friends. And making safety a priority can ensure that boating stays fun.
- In 2009, 3,358 people were injured and 736 died in boating incidents. Of those who drowned, 9 out of 10 were not wearing life jackets.
- Of the people who died in a boating incident in 2009, more than 7 out of 10 (73%) drowned. More than 90 percent of the people who drowned were not wearing a life jacket.
- Alcohol use was the leading contributing factor in fatal boating incidents.

What physical changes occur, in general, as a person ages… and how can this affect their work?
Our bodies change as we age. People reach full physical maturity or development at around the age of 25 years. Then after a period of relative stability, our bodies begin to show signs of aging. Most of these changes are first noticed at ages 40 or 50, but changes can occur (or start) as early as 20 or 25. These changes include:
- Maximum muscular strength and range of joint movement: In general, people lose 15 to 20% of their strength from the ages of 20 to 60. However, every person is different and there is a large range between individuals. However, most jobs do not require a person to use all their strength. Older employees may be able to perform the same tasks as a younger worker, but they may be working closer to their maximum level. The musculoskeletal system weakens over time, resulting in a decreased capacity for load-bearing work. Keep in mind that, for example, highly repetitive motions — doing the same thing, over and over again — can cause physical problems at any age.
- As we age, the body loses some ‘range of motion’ and flexibility. People may be used to certain range of movements at one task or workstation. Being less flexible or able to reach could cause problems in some unpredictable situations that require unusual movements.
- Cardiovascular and respiratory systems: The ability of the heart, lungs and circulatory system to carry oxygen decreases. Between the age of 30 and 65, the functional breathing capacity can reduce by 40%. These changes can affect the ability to do extended heavy physical labour, reduce the body’s ability to adjust to hot and cold conditions.
- Regulation of posture and balance: In general people may find it harder to maintain good posture and balance. When seated or standing still, this may not be a problem. However, accidents that happen because someone loses their balance do happen more often with age. Work that requires precise adjustments, strong muscular effort (including lifting and carrying), joint movements at extreme angles, or those done on a slippery or unstable surface, will be affected by poorer posture. Unexpected bumps or shocks may cause a more serious problem than with a younger worker.
- Sleep Regulation: As we age, our body is not able to regulate sleep as well as it used to. How long a person sleeps, and how well they sleep, can additionally be disrupted by changing work hours or by light and noise. The impact on employees is especially a concern for older shift or night workers. They might need more recovery time between shifts or extended workdays. Use of shift rotations that are the least disruptive to sleep patterns are preferred.
- Thermoregulation (Body Temperature): Our bodies are less able to maintain internal temperatures as well as less able to adjust to changes in external temperature or due to physical activity. This change means that older workers may find heat or cold more difficult to deal with than when they were younger. It also means that if they are doing hard manual labour, they may get overheated more easily.
- Vision: Vision changes with age. We will notice we cannot see or read from certain distances as well as we used to. This reduction in the “amplitude of accommodation” (the ability to see or adjust focus in certain distance ranges) is normally corrected with prescription glasses. Changes also occur in the peripheral visual field (how well you can see in the areas to the side of you, that you’re not directly looking at), visual acuity (how exact, clear, and “unfuzzy” things appear), depth perception (how far away things seem), and resistance to glare, and light transmission. These changes are normally not noticed by a person unless there is poor lighting or there are sources of glare. Someone might also notice that they can’t see as well when they’re reading something when text size is small, or when there is poor contrast between the text and the background. Brighter lighting (that is suitable for the task) and well laid-out documents which avoid small print are important.
- Auditory (Hearing): Hearing also changes. We may not be able to hear as well at higher frequencies (high pitch sounds). Most often, this change is noticed as the inability to listen to a particular voice or sound in a noisy environment. As well, people who work with a lot of background or noise may have difficulty hearing verbal instructions.
