Safety Helmet Standards and Classes | Health and Safety


We’re going to be talking about Safety hard hat standards. OSHA standards state that a safety helmet must be worn when working in areas where there is potential for injury to the head from falling objects. There are two types of hard hats classified by ANSI standard, Z89.1-2014 for different levels of protection.
Safety Helmet Standards and Classes | Health and Safety

Type (1)-hard hats are designed to protect only from the top of your head.
Class C-hard hats are considered conductive and do not provide any electrical protection. 

These are typically vented and only protect workers from impact, this helmet becomes class-E compliant.-hard hats are designed to reduce force from lateral the impact such as an off-center impact, and side-impact, as well as top of the head.
These helmets have visible padding on the sides. The helmet sets the standard in type 1 protection. With a strong chin strap, vented holes, and a webbing suspension system, this helmet is the preferred choice for comfort and strength. Hard hats must also be worn in areas where there’s a risk of exposure to electrical conductors, thus requiring a further level of classification. 

Class C (Conductive)-

Hard hats are considered conductive and do not provide any electrical protection, these are typically vented and only protect workers from impact, this helmet becomes class-E compliant.

Class E (Electric)-

Hard hats offer protection from high voltage conductors up to 20,000 volts, and cannot have any vents in the design. 

Class G (General)-

Offers protection from low voltage conductors up to 2,200 volts, they must also be free of holes for ventilation. ANSI requires proper labeling of a hard hat that identifies the standards to which it was designed to meet. If the label is missing or no longer legible, the helmet must be replaced.

Hard Hats are not designed to last forever. Service life begins from the time it is put into service and that date should be properly labeled and documented. Suspension should be replaced after 12 months and the helmet should be replaced after no more than 5 years. If the hard hat sustains an impact, it must be retired immediately even if there is no visible damage. Proper inspection should be taken each time the helmet is worn. Suspension should be installed and worn as the manufacturer intended.

Exposure to paint and chemicals may damage the structure of the helmet, therefore steps must be taken to remove paint or chemicals after every use. Pressure-sensitive, non-metallic stickers and self-adhesive tape are typically accepted, however, I strongly recommend you refer to the manufacturer’s specifications before applying anything on the surface of the helmet.

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

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

The Respiratory System of Human Body

Image
  We are going to discuss about the respiratory system in this article. One of the most vital organ systems of our body is the respiratory system. We breathe about 16,000 to 24,000 times per day, which exchanges about 11,000 liters of air with the atmosphere in this process. The oxygen of the atmospheric air is delivered to the human body, which is then utilized by all the tissues, and the carbon dioxide which is produced by the human body is exported to the lungs and then exchanged with the atmospheric air, In this article we will first talk about the brief anatomy and physiology of the human respiratory system and then we will discuss how the gas transport to the alveoli occurs, we will talk about how the human respiratory system works together with the circulatory system and then we will talk about how the gas exchange happens in the alveoli.   So, first coming to the anatomy and physiology of the human respiratory system, the vocal cords present in the larynx divide the respira

Safeguarding of Machinery

Image
There are many types of guards we use in the industry to protect our people from injuries. As we know lots of incidents, we face on job site leading to loss of time, permanent disability to the injured person and loss of company reputation which can lead to loss of businesses in future. Here we shall discuss the types of fixed guards we see on the job site in detail to understand the use and benefits of them. Fixed Guards There are three types of fixed guard: 1. Fixed Enclosing Guards,  2. Perimeter Fences, and  3. Fixed Distance Guards. 1. Fixed Guards: Fixed guards have no moving parts and are fastened in a constant position relative to the danger zone. they are kept in place either permanently by welding, or by means of fasteners making removal/opening impossible without using tools. If by themselves, or in conjunction with the structure of the equipment, they enclose the dangerous parts, fixed guards meet the requirements of the first level of the hierarchy. Fix
