Hearing Protection Noise is an unwanted sound that can affect job performance, safety, and your health. Psychological effects of noise include annoyance and disruption of concentration. Physical effects include loss of hearing, pain, nausea, and interference with communications when the exposure is severe. Hearing protection is essential when noise exposures can't be controlled at their source. Both earplugs and earmuffs provide a physical barrier that reduces inner ear noise levels inner ear and prevents hearing loss from occurring. However, people often resist wearing these or use them incorrectly. Employees resist wearing hearing protection more than any other type of personal protective equipment. One...

Boiler Safety Workers that use, maintain, and service boilers know that they can be potentially dangerous. Boilers are gas-fired or electric closed vessels that heat water or other liquid to generate steam. The steam is superheated under pressure and used for power, heating or other industrial purposes. Though boilers are usually equipped with a pressure relief valve, if the boiler fails to contain the expansion pressure, the steam energy is released instantly. This combination of exploding metal and superheated steam can be extremely dangerous. Only trained and authorized workers should operate a boiler. Workers should be familiar with the boiler manufacturers operating...

Power Tool Safety Power tools get jobs done with efficiency and reduced effort. But with power comes responsibility. Power tools can cause injury and even death if they are not used properly. Appropriate training, safe work practices, and power tool maintenance are key to preventing accidents. Only trained workers should use power tools on the job. Training should include reviewing the instruction manual, how to inspect the tools before each use, and following the manufacturer’s maintenance schedule. When maintaining and inspecting power tools, keep the followings tips in mind: Use properly sized fittings and parts for the power tools. Keep tool cutting edges...

Aircraft Maintenance Safety Aircraft maintenance work includes inspection and repair of aircraft structures, coatings, and systems in hangars and on the air field. Good training and work practices ensure aircraft and worker safety. Tall, heavy aircraft make it hard to see people on the ground when maneuvering in the hangar or maintenance area. Watch and communicate with the aircraft operator to avoid caught/crush accidents (getting run over by a tire or colliding with a wing or tail). Never enter the ramp or flightline without permission from the air field controller. Work at a steady pace. Rushing your work increases aircraft turnaround and accidents....

Occupational Vibration Exposure Many workers do not think that their exposure to vibration could be a health hazard.  Vibration exposure is more than just a nuisance.  Constant exposure to vibration has been known to cause serious health problems such as back pain, carpal tunnel syndrome, and vascular disorders.  Vibration related injury is especially prevalent in occupations that require outdoor work, such as forestry, farming, transportation, shipping, and construction.  There are two classifications for vibration exposure:  whole-body vibration and hand and arm vibration.  These two types of vibration have different sources, affect different areas of the body, and produce different symptoms. Whole-body vibration...

Hearing Protection Devices Hearing protection devices (HPD) such as earmuffs and earplugs can be an effective measure to protect hearing in noisy work environments.  However, hearing protection devices are only effective if they are properly sized and carefully fitted into or over the ear.  The two common HPD categories are earplugs and earmuffs. There are several common types of hearing protection devices: Formable earplugs made of expandable foam.  One size fits most people. Premolded earplugs made from flexible plastics.  Often sold in different sizes, they should be selected to provide best fit for each ear. Semi-aural devices, or canal caps, consisting of...
