International Organization for Standardization-ISO | Health and Safety

ISO stands for the International Organization for Standardization, it was French and so that's why it comes out ISO instead of “IOS”. The ISO Technical Committee 145 standardizes graphical symbols on a worldwide basis, as well as safety sign formats and safety label formats and colors and how you integrate the symbols and colors onto signage.
Yellow- So the safety can be communicated on a worldwide basis consistently that's the key consistency yellow is used on a warning sign and your warning triangle and it's the background color for a black symbol it indicates that our potential hazard is present.
Red- There are prohibition signs, it's a red circle with a red slash going through it at a 45-degree angle upper left to lower right and it has a black graphic symbol behind it and those signs indicate something that you should not do or you have the potential to interact with a hazard and get hurt.
Blue- You have mandatory action signs and these are blue circles white graphic and they indicate an action that you should take in order to avoid a hazard typically you might use those for like personal protective equipment, wearing hardhats, wearing eye protection, type of thing.
You have the symbols of having to do with fire equipment there red square with a white flame determinative element and a white graphical symbol indicating what the equipment is such as a fire extinguisher or a fire alarm.
Green- You have green squares with white graphics in them and therefore the location of safety equipment or a safe condition like the cross which would be for use for first-aid, the Running Man going through an open door, and that's to indicate that there’s an emergency exit in this direction.
The type of thing so green, red, blue and yellow in ISO they all indicate a different type of safety message so as you get closer to the sign you see, not just the color but the symbol and the symbol would tell you what these specific messages that are the vocabulary of how color is used in ISO.

Office Ergonomics-Contact Stress: This Is What Professionals Do

Image
  Contact Stress- Contact stress results from occasional repeated or continuous contact between sensitive body tissue and a hard or sharp object contact stress commonly affects the soft tissue on the fingers, palms, forearms, thighs, calves and feet. Prolonged contact stress can inhibit blood flow, tendon and muscle movement and nerve function. One common example is resting wrists or elbows on the sharp edge of a desk or workstation, while performing tasks this can take place, while typing with the keyboard either too close or too far away using the mouse for a prolonged period of time can also lead to contact stress. The stress can be prevented by repositioning commonly used workstation items floating hands above the keyboard and reducing tension in the shoulders eliminates potential contact stress using a keyboard tray eliminates contact with a work surface edge and keeps your arms in a neutral position. Optimal neutral arm position has the arms relaxed at the side of the body with a

Different Types of Flanges and Valves in the Industry | Health and Safety

Image
Types of Flanges Flanges have been designed and developed to be used in countless application each one has its own special characteristics and should be carefully selected to meet specific functional requirements. The following flanges will be discussed in this chapter weld neck, threaded, socket weld, slip-on, lap-joint, blind, Orifice, and reducing flange. 1. Weld Neck Flange- Weld Neck Flanges transfer the stress from the flange itself into the connected pipe. These are used mainly for all processes and critical services where the weld joints need a radiographic inspection. 2. Socket Weld Flange-  Socket Weld Flanges are welded on one side only these are used for small board blanks only 3. Threaded Flange- Threaded Flanges are used on non-critical piping for air, water, or nitrogen. Usually, the piping material used for threaded piping is Galvanized CS. 4. Lap Joint Flanges- Lap Joint Flanges are used with stub ends. These are welded with pipes & fl

Hydrostatic Pressure Testing of Fire Extinguisher | Health and Safety

Image
We are going discuss hydrostatic test of stored pressure type fire extinguisher what you're going to see full hydrostatic test here, we wanted to give you guys a little bit of idea on how that works whether you are a fire equipment distributor or an end-user.  First, you need to take the extinguisher apart, then get the top off and then go ahead and clean off the tube then clean out the head of the extinguisher you can see there's a lot of foreign matter and dust particles and things inside, blow all that out, run a nylon brush through and then check that valve stem and the spring and make sure that everything is in good working condition. remember that the only difference between six-year care down and the hydrostatic test is simply that you need to fill that shelf full of water you need to pressurize it to three times its operating pressure and a hydrostatic test you need to record all that as opposed is just doing an internal examination and external examination o

Safety of Pressure Vessels and Pressure System

Image
  Pressure Vessels A pressure vessel consists mainly of a series of sheets of metal suitably shaped and welded together. They are designed to contain stored energy above atmospheric pressure. Pressure vessels, typically steam boilers and air receivers, are inherently potentially dangerous items of plant and there is a long and tragic history of accidents associated with them. -Typically injuries relate from: The impact from the blast of an explosion or release of compressed liquid or gas. Impact form parts of equipment that fail or any flying debris. Contact with the released liquid or gas, such as steam, and fire resulting from the escape of flammable liquids or gases; and Oxygen depletion or enrichment. -The typical causes of pressure system failure are: Poor equipment and or system design. Poor maintenance of equipment. An unsafe system of work. Operator error, poor training, and supervision. Poor installation: and Inadequate repairs or modification. St
