Occupational Noise and Exposure | Health and Safety

Welcome to occupational noise exposure, overview 22 million workers are exposed to potentially damaging noise at work each year. Last year US business paid more than 1.5 million in penalties for not protecting workers from noise. While it’s impossible to put a number to the human toll of hearing loss, an estimated 242 million is spent annually on workers' compensation for hearing loss disability objectives. Today you will learn about occupational noise exposure and the risks associated with it. While on the job you will learn proper steps and procedures for hearing protection and what is required to protect yourself. You will see examples of proper hearing protection that you will use to help prevent occupational noise exposure.

What is the noise?

Noise and vibration are both fluctuations in the pressure of air which affect the human body vibrations that are detected by the human ear are classified as sound the term noise indicates unwanted sound. Noise is measured in units of sound pressure called decibels or dB. Exposure to high levels of noise can cause permanent hearing loss, neither surgery nor hearing aid can help correct this type of hearing loss. Short-term exposure to loud noise can also cause a temporary change in hearing. An example of this is tendinitis, while short-term exposure may go away with. Within minutes long-term exposure or repeated exposure to loud noise can lead to permanent effects you.

What can be done to reduce the hazard of noise?

Hearing protection devices such as earmuffs and plugs are considered an acceptable but less desirable option to control exposures to noise and are generally used during the time. It is necessary to implement engineering or administrative controls, when such controls are not feasible or when workers hearing tests indicate significant hearing damage. There are some hearing protection examples earmuffs foam insert earplug sand semi RL caps. OSHA standard to “Occupational noise exposure 9-CFR-1910.95” coverage protection beats the effects of noise exposure and what should be provided when the sound levels exceed.
Octave band sound pressure levels may be converted to the equivalent a weighted sound level by plugging in on the graph and noting the elevated sound level corresponding to the point of the highest penetration in sound level contours. This section deals with employees when they are subjected to sounds exceeding those listed in the table on the right in this case feasible administrative or engineering controls should be utilized. If such controls failed to reduce sound levels, personal protective equipment should be provided. We use two new symbols within the sound levels, the employer shall administer a continuing effective hearing and conservation program, whenever an employee’s noise exposure is equal or exceeds an 8-hour TWA sound level of 85 dB measured on the ACL or given a dose of 50%. A piece of information indicates that any employee exposure not equal or exceed an 8-hour TWA of 85 dB, employers shall develop and implement a monitoring program. Employers shall make hearing protectors available to all employees exposed to an 8-hour TWA of 85 dB or greater, at no cost to the employees hearing protectors shall be replaced as necessary. The employer shall ensure that hearing protectors are worn when they are required.

Reminder!

Always wear proper PPE, life is worth listening to wear hearing protection.

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
