OSHA's term for this site-constructed precautionary device is a slide guard. Therefore, it is unlikely that such an assembly was intended to prevent a rapidly sliding 200-pound roofer from falling off of an 8:12 pitch roof. The broad term 'toe board' is clearly defined by OSHA in 1926.500(b): 'A low protective barrier that will prevent the fall of materials and equipment to lower levels and provide protection from falls for personnel.'ДЄNSI describes a toe board as a component of a guardrail system, as having a nominal 4-inch height and structure capable of resisting 50 pounds of force applied horizontally at mid-length without failure. I have even heard them termed 'toe boards' in the Northwest, which obviously contradicts that lowest portion of a guardrail system intended to prevent workers feet and debris from accidentally slipping off a work level or scaffold platform.

Some builders here in the Northeast call them 'strong-backs' while one contractor in Colorado named them 'cripples' (for obvious reasons).

It can even signify you're more likely to die at a younger age than average. If your heartbeat is regularly at or above the high end of this range, you may be at a higher risk of heart disease. This is more likely if you also notice fatigue and occasional dizziness. A heart rate that is at the very low end of the range or below can signify something is wrong with the way your heart is transmitting electrical signals. Usually a low resting heart rate suggests good physical fitness. This can vary depending on a lot of things, like how much caffeine you've had recently, how active you've been in the last two hours, and whether or not you're anxious or stressed. And tracking it over time can help your doctor anticipate future problems.ДЄ normal resting heart rate is 60 to 100 beats per minute (BPM). How fast your heart beats can reveal a lot about your health. NeckД«y listening to the sides of the neck with a stethoscope, your doctor can screen for carotid narrowing by detecting a carotid bruit, an abnormal swooshing sound in the carotid artery. The various sounds can help your doctor screen for and/or diagnose lung problems. The stethoscope can let your doctor hear sounds like crackles, rales (sounds like rattling or crumpling cellophane) or detect no sounds in the lungs where some should be present.

The stethoscope can let the doctor know immediately if the heart is not beating normally. Murmurs can also indicate a variety of problems with heart valves. Most murmurs are normal, but some can indicate problems such as a fever, anemia, high blood pressure, or an overactive thyroid.

Heart:Д«y listening carefully to your heartbeat, a doctor can know right away if you have a heart murmur, which is another word for an unusual whooshing or swishing sound in your heart. It is also used to listen to your lungs and neck. Making sure your heart is in good working order is perhaps the primary job of a stethoscope. A stethoscope magnifies sounds like your heart beat. A doctor's stethoscope is so important that these handy hearing devices are immediately recognized by most people.
